CREATE PROCEDURE

SQL Server 2000

  Topic last updated -- June 2007

Creates a stored procedure, which is a saved collection of Transact-SQL statements that can take and return user-supplied parameters.

Procedures can be created for permanent use or for temporary use within a session (local temporary procedure) or for temporary use within all sessions (global temporary procedure).

Stored procedures can also be created to run automatically when Microsoft® SQL Server™ starts.

Syntax

CREATE PROC [ EDURE ] [ owner. ] procedure_name [ ; number ]
    [ { @parameter data_type }
        
[ VARYING ] [ = default ] [ OUTPUT ]
    
] [ ,...n ]

[ WITH
    { RECOMPILE | ENCRYPTION | RECOMPILE , ENCRYPTION } ]

[ FOR REPLICATION ]

AS sql_statement [ ...n ]

Arguments

owner

Is the name of the user ID that owns the stored procedure. owner must be either the name of the current user or the name of a role that a current user is a member of.

procedure_name

Is the name of the new stored procedure. Procedure names must conform to the rules for identifiers and must be unique within the database and its owner. For more information, see Using Identifiers.

Local or global temporary procedures can be created by preceding the procedure_name with a single number sign (#procedure_name) for local temporary procedures and a double number sign (##procedure_name) for global temporary procedures. The complete name, including # or ##, cannot exceed 128 characters. Specifying the procedure owner name is optional.

;number

Is an optional integer used to group procedures of the same name so they can be dropped together with a single DROP PROCEDURE statement. For example, the procedures used with an application called orders may be named orderproc;1, orderproc;2, and so on. The statement DROP PROCEDURE orderproc drops the entire group. If the name contains delimited identifiers, the number should not be included as part of the identifier; use the appropriate delimiter around procedure_name only.

@parameter

Is a parameter in the procedure. One or more parameters can be declared in a CREATE PROCEDURE statement. The value of each declared parameter must be supplied by the user when the procedure is executed (unless a default for the parameter is defined or the value is set to equal another parameter). A stored procedure can have a maximum of 2,100 parameters.

Specify a parameter name using an at sign (@) as the first character. The parameter name must conform to the rules for identifiers. Parameters are local to the procedure; the same parameter names can be used in other procedures. By default, parameters can take the place only of constants; they cannot be used in place of table names, column names, or the names of other database objects. For more information, see EXECUTE.

data_type

Is the parameter data type. All data types, except the table data type, can be used as a parameter for a stored procedure. However, the cursor data type can be used only on OUTPUT parameters. When you specify a data type of cursor, the VARYING and OUTPUT keywords must also be specified. For more information about SQL Server - supplied data types and their syntax, see Data Types.

Note  There is no limit on the maximum number of output parameters that can be of cursor data type.

VARYING

Specifies the result set supported as an output parameter (constructed dynamically by the stored procedure and whose contents can vary). Applies only to cursor parameters.

default

Is a default value for the parameter. If a default is defined, the procedure can be executed without specifying a value for that parameter. The default must be a constant or it can be NULL. It can include wildcard characters (%, _, [], and [^]) if the procedure uses the parameter with the LIKE keyword.

OUTPUT

Indicates that the parameter is a return parameter. The value of this option can be returned to EXEC[UTE]. Use OUTPUT parameters to return information to the calling procedure. Text, ntext, and image parameters can be used as OUTPUT parameters. An output parameter using the OUTPUT keyword can be a cursor placeholder.

n

Is a placeholder indicating that a maximum of 2,100 parameters can be specified.

{RECOMPILE | ENCRYPTION | RECOMPILE, ENCRYPTION}

RECOMPILE indicates that SQL Server does not cache a plan for this procedure and the procedure is recompiled at run time. Use the RECOMPILE option when using atypical or temporary values without overriding the execution plan cached in memory.

ENCRYPTION indicates that SQL Server converts the original text of the CREATE PROCEDURE statement to an obfuscated format. Note that obfuscated stored procedures can be reverse engineered because SQL Server must de-obfuscate procedures for execution. In SQL Server 2000, the obfuscated text is visible in the syscomments system table and may be susceptible to de-obfuscation attempts.

Using ENCRYPTION prevents the procedure from being published as part of SQL Server replication.

Note  During an upgrade, SQL Server uses the obfuscated comments stored in syscomments to re-create obfuscated procedures.

FOR REPLICATION

Specifies that stored procedures created for replication cannot be executed on the Subscriber. A stored procedure created with the FOR REPLICATION option is used as a stored procedure filter and only executed during replication. This option cannot be used with the WITH RECOMPILE option.

AS

Specifies the actions the procedure is to take.

sql_statement

Is any number and type of Transact-SQL statements to be included in the procedure. Some limitations apply.

n

Is a placeholder that indicates multiple Transact-SQL statements may be included in this procedure.

Remarks

The maximum size of a stored procedure is 128 MB.

A user-defined stored procedure can be created only in the current database (except for temporary procedures, which are always created in tempdb). The CREATE PROCEDURE statement cannot be combined with other Transact-SQL statements in a single batch.

Parameters are nullable by default. If a NULL parameter value is passed and that parameter is used in a CREATE or ALTER TABLE statement in which the column referenced does not allow NULLs, SQL Server generates an error. To prevent passing a NULL parameter value to a column that does not allow NULLs, add programming logic to the procedure or use a default value (with the DEFAULT keyword of CREATE or ALTER TABLE) for the column.

Security Note  Validate all user input. Do not concatenate user input before validating it. Never execute a command constructed from unvalidated user input. For more information, see Validating User Input.

It is recommended that you explicitly specify NULL or NOT NULL for each column in any CREATE TABLE or ALTER TABLE statement in a stored procedure, such as when creating a temporary table. The ANSI_DFLT_ON and ANSI_DFLT_OFF options control the way SQL Server assigns the NULL or NOT NULL attributes to columns if not specified in a CREATE TABLE or ALTER TABLE statement. If a connection executes a stored procedure with different settings for these options than the connection that created the procedure, the columns of the table created for the second connection can have different nullability and exhibit different behaviors. If NULL or NOT NULL is explicitly stated for each column, the temporary tables are created with the same nullability for all connections that execute the stored procedure.

SQL Server saves the settings of both SET QUOTED_IDENTIFIER and SET ANSI_NULLS when a stored procedure is created or altered. These original settings are used when the stored procedure is executed. Therefore, any client session settings for SET QUOTED_IDENTIFIER and SET ANSI_NULLS are ignored during stored procedure execution. SET QUOTED_IDENTIFIER and SET ANSI_NULLS statements that occur within the stored procedure do not affect the functionality of the stored procedure.

Other SET options, such as SET ARITHABORT, SET ANSI_WARNINGS, or SET ANSI_PADDINGS are not saved when a stored procedure is created or altered. If the logic of the stored procedure is dependent on a particular setting, include a SET statement at the start of the procedure to ensure the proper setting. When a SET statement is executed from a stored procedure, the setting remains in effect only until the stored procedure completes. The setting is then restored to the value it had when the stored procedure was called. This allows individual clients to set the options wanted without affecting the logic of the stored procedure.

Note  Whether SQL Server interprets an empty string as either a single space or as a true empty string is controlled by the compatibility level setting. If the compatibility level is less than or equal to 65, SQL Server interprets empty strings as single spaces. If the compatibility level is equal to 70, SQL Server interprets empty strings as empty strings. For more information, see sp_dbcmptlevel.

Getting Information About Stored Procedures

To display the text used to create the procedure, execute sp_helptext in the database in which the procedure exists with the procedure name as the parameter.

Note  Stored procedures created with the ENCRYPTION option cannot be viewed with sp_helptext.

For a report on the objects referenced by a procedure, use sp_depends.

To rename a procedure, use sp_rename.

Referencing Objects

SQL Server allows the creation of stored procedures that reference tables that do not yet exist. At creation time, only syntax checking is done. The stored procedure is compiled to generate an execution plan when executed if a valid plan does not already exist in the cache. Only during compilation are all objects referenced in the stored procedure resolved. Thus, a syntactically correct stored procedure that references tables that do not exist can be created successfully; however, the store procedure will fail at run time if the referenced tables do not exist. For more information, see Deferred Name Resolution and Compilation.

Deferred Name Resolution and Compatibility Level

SQL Server allows Transact-SQL stored procedures to refer to tables that do not exist at creation time. This ability is called deferred name resolution. An error message is returned at run time if the table or column referenced does not exist. If the Transact-SQL stored procedure refers to a table defined within the stored procedure, a warning is issued at creation time if the compatibility level setting (set by executing sp_dbcmptlevel) is 65. For more information, see sp_dbcmptlevel and Deferred Name Resolution and Compilation.

Executing Stored Procedures

When a CREATE PROCEDURE statement is executed successfully, the procedure name is stored in the sysobjects system table and the text of the CREATE PROCEDURE statement is stored in syscomments. When executed for the first time, the procedure is compiled to determine an optimal access plan to retrieve the data.

Parameters Using the cursor Data Type

Stored procedures can use the cursor data type only for OUTPUT parameters. If the cursor data type is specified for a parameter, both the VARYING and OUTPUT parameters are required. If the VARYING keyword is specified for a parameter, the data type must be cursor and the OUTPUT keyword must be specified.

Note  The cursor data type cannot be bound to application variables through the database APIs such as OLE DB, ODBC, ADO, and DB-Library. Because OUTPUT parameters must be bound before an application can execute a stored procedure, stored procedures with cursor OUTPUT parameters cannot be called from the database APIs. These procedures can be called from Transact-SQL batches, stored procedures, or triggers only when the cursor OUTPUT variable is assigned to a Transact-SQL local cursor variable.

Cursor Output Parameters

The following rules pertain to cursor output parameters when the procedure is executed:

  • For a forward-only cursor, the rows returned in the cursor's result set are only those rows at and beyond the position of the cursor at the conclusion of the stored procedure executed, for example:
    • A nonscrollable cursor is opened in a procedure on a result set named RS of 100 rows.

    • The procedure fetches the first 5 rows of result set RS.

    • The procedure returns to its caller.

    • The result set RS returned to the caller consists of rows from 6 through 100 of RS, and the cursor in the caller is positioned before the first row of RS.
  • For a forward-only cursor, if the cursor is positioned before the first row upon completion of the stored procedure, the entire result set is returned to the calling batch, stored procedure, or trigger. When returned, the cursor position is set before the first row.

  • For a forward-only cursor, if the cursor is positioned beyond the end of the last row upon completion of the stored procedure, an empty result set is returned to the calling batch, stored procedure, or trigger.

    Note  An empty result set is not the same as a null value.

  • For a scrollable cursor, all the rows in the result set are returned to the calling batch, stored procedure, or trigger at the conclusion of the execution of the stored procedure. When returned, the cursor position is left at the position of the last fetch executed in the procedure.

  • For any type of cursor, if the cursor is closed, then a null value is passed back to the calling batch, stored procedure, or trigger. This will also be the case if a cursor is assigned to a parameter, but that cursor is never opened.

Note  The closed state matters only at return time. For example, it is valid to close a cursor part way through the procedure, to open it again later in the procedure, and return that cursor's result set to the calling batch, stored procedure, or trigger.

Temporary Stored Procedures

SQL Server supports two types of temporary procedures: local and global. A local temporary procedure is visible only to the connection that created it. A global temporary procedure is available to all connections. Local temporary procedures are automatically dropped at the end of the current session. Global temporary procedures are dropped at the end of the last session using the procedure. Usually, this is when the session that created the procedure ends.

Temporary procedures named with # and ## can be created by any user. When the procedure is created, the owner of the local procedure is the only one who can use it. Permission to execute a local temporary procedure cannot be granted for other users. If a global temporary procedure is created, all users can access it; permissions cannot be revoked explicitly. Explicitly creating a temporary procedure in tempdb (naming without a number sign) can be performed only by those with explicit CREATE PROCEDURE permission in the tempdb database. Permission can be granted and revoked from these procedures.

Note  Heavy use of temporary stored procedures can create contention on the system tables in tempdb and adversely affect performance. It is recommended that sp_executesql be used instead. sp_executesql does not store data in the system tables and therefore avoids the problem.

Automatically Executing Stored Procedures

One or more stored procedures can execute automatically when SQL Server starts. The stored procedures must be created by the system administrator and executed under the sysadmin fixed server role as a background process. The procedure(s) cannot have any input parameters.

There is no limit to the number of startup procedures you can have, but be aware that each consumes one connection while executing. If you must execute multiple procedures at startup but do not need to execute them in parallel, make one procedure the startup procedure and have that procedure call the other procedures. This uses only one connection.

Execution of the stored procedures starts when the last database is recovered at startup. To skip launching these stored procedures, specify trace flag 4022 as a startup parameter. If you start SQL Server with minimal configuration (using the -f flag), the startup stored procedures are not executed. For more information, see Trace Flags.

To create a startup stored procedure, you must be logged in as a member of the sysadmin fixed server role and create the stored procedure in the master database.

Use sp_procoption to:

  • Designate an existing stored procedure as a startup procedure.

  • Stop a procedure from executing at SQL Server startup.
Stored Procedure Nesting

Stored procedures can be nested; that is one stored procedure calling another. The nesting level is incremented when the called procedure starts execution, and decremented when the called procedure finishes execution. Exceeding the maximum levels of nesting causes the whole calling procedure chain to fail. The current nesting level is returned by the @@NESTLEVEL function.

To estimate the size of a compiled stored procedure, use these Performance Monitor Counters.

Performance Monitor object name Performance Monitor Counter name
SQLServer: Buffer Manager Procedure Cache Pages
SQLServer: Cache Manager Cache Hit Ratio
  Cache Pages
  Cache Object Counts*

* These counters are available for various categories of cache objects including adhoc sql, prepared sql, procedures, triggers, and so on.

For more information, see SQL Server: Buffer Manager Object and SQL Server: Cache Manager Object.

sql_statement Limitations

Any SET statement can be specified inside a stored procedure except SET SHOWPLAN_TEXT and SET SHOWPLAN_ALL, which must be the only statements in the batch. The SET option chosen remains in effect during the execution of the stored procedure and then reverts to its former setting.

Inside a stored procedure, object names used with certain statements must be qualified with the name of the object owner if other users are to use the stored procedure. The statements are:

  • ALTER TABLE

  • CREATE INDEX

  • CREATE TABLE

  • All DBCC statements

  • DROP TABLE

  • DROP INDEX

  • TRUNCATE TABLE

  • UPDATE STATISTICS
Permissions

CREATE PROCEDURE permissions default to members of the sysadmin fixed server role, and the db_owner and db_ddladmin fixed database roles. Members of the sysadmin fixed server role and the db_owner fixed database role can transfer CREATE PROCEDURE permissions to other users. Permission to execute a stored procedure is given to the procedure owner, who can then set execution permission for other database users.

Examples
A. Use a simple procedure with a complex SELECT

This stored procedure returns all authors (first and last names supplied), their titles, and their publishers from a four-table join. This stored procedure does not use any parameters.

USE pubs
IF EXISTS (SELECT name FROM sysobjects 
         WHERE name = 'au_info_all' AND type = 'P')
   DROP PROCEDURE au_info_all
GO
CREATE PROCEDURE au_info_all
AS
SELECT au_lname, au_fname, title, pub_name
   FROM authors a INNER JOIN titleauthor ta
      ON a.au_id = ta.au_id INNER JOIN titles t
      ON t.title_id = ta.title_id INNER JOIN publishers p
      ON t.pub_id = p.pub_id
GO

The au_info_all stored procedure can be executed in these ways:

EXECUTE au_info_all
-- Or
EXEC au_info_all

Or, if this procedure is the first statement within the batch:

au_info_all
B. Use a simple procedure with parameters

This stored procedure returns only the specified authors (first and last names supplied), their titles, and their publishers from a four-table join. This stored procedure accepts exact matches for the parameters passed.

USE pubs
IF EXISTS (SELECT name FROM sysobjects 
         WHERE name = 'au_info' AND type = 'P')
   DROP PROCEDURE au_info
GO
USE pubs
GO
CREATE PROCEDURE au_info 
   @lastname varchar(40), 
   @firstname varchar(20) 
AS 
SELECT au_lname, au_fname, title, pub_name
   FROM authors a INNER JOIN titleauthor ta
      ON a.au_id = ta.au_id INNER JOIN titles t
      ON t.title_id = ta.title_id INNER JOIN publishers p
      ON t.pub_id = p.pub_id
   WHERE  au_fname = @firstname
      AND au_lname = @lastname
GO

The au_info stored procedure can be executed in these ways:

EXECUTE au_info 'Dull', 'Ann'
-- Or
EXECUTE au_info @lastname = 'Dull', @firstname = 'Ann'
-- Or
EXECUTE au_info @firstname = 'Ann', @lastname = 'Dull'
-- Or
EXEC au_info 'Dull', 'Ann'
-- Or
EXEC au_info @lastname = 'Dull', @firstname = 'Ann'
-- Or
EXEC au_info @firstname = 'Ann', @lastname = 'Dull'

Or, if this procedure is the first statement within the batch:

au_info 'Dull', 'Ann'
-- Or
au_info @lastname = 'Dull', @firstname = 'Ann'
-- Or
au_info @firstname = 'Ann', @lastname = 'Dull'
C. Use a simple procedure with wildcard parameters

This stored procedure returns only the specified authors (first and last names supplied), their titles, and their publishers from a four-table join. This stored procedure pattern matches the parameters passed or, if not supplied, uses the preset defaults.

USE pubs
IF EXISTS (SELECT name FROM sysobjects 
      WHERE name = 'au_info2' AND type = 'P')
   DROP PROCEDURE au_info2
GO
USE pubs
GO
CREATE PROCEDURE au_info2
   @lastname varchar(30) = 'D%',
   @firstname varchar(18) = '%'
AS 
SELECT au_lname, au_fname, title, pub_name
FROM authors a INNER JOIN titleauthor ta
   ON a.au_id = ta.au_id INNER JOIN titles t
   ON t.title_id = ta.title_id INNER JOIN publishers p
   ON t.pub_id = p.pub_id
WHERE au_fname LIKE @firstname
   AND au_lname LIKE @lastname
GO

The au_info2 stored procedure can be executed in many combinations. Only a few combinations are shown here:

EXECUTE au_info2
-- Or
EXECUTE au_info2 'Wh%'
-- Or
EXECUTE au_info2 @firstname = 'A%'
-- Or
EXECUTE au_info2 '[CK]ars[OE]n'
-- Or
EXECUTE au_info2 'Hunter', 'Sheryl'
-- Or
EXECUTE au_info2 'H%', 'S%'
D. Use OUTPUT parameters

OUTPUT parameters allow an external procedure, a batch, or more than one Transact-SQL statements to access a value set during the procedure execution. In this example, a stored procedure (titles_sum) is created and allows one optional input parameter and one output parameter.

First, create the procedure:

USE pubs
GO
IF EXISTS(SELECT name FROM sysobjects
      WHERE name = 'titles_sum' AND type = 'P')
   DROP PROCEDURE titles_sum
GO
USE pubs
GO
CREATE PROCEDURE titles_sum @TITLE varchar(40) = '%', @SUM money OUTPUT
AS
SELECT 'Title Name' = title
FROM titles 
WHERE title LIKE @TITLE 
SELECT @SUM = SUM(price)
FROM titles
WHERE title LIKE @TITLE
GO

Next, use the OUTPUT parameter with control-of-flow language.

Note  The OUTPUT variable must be defined during the table creation as well as during use of the variable.

The parameter name and variable name do not have to match; however, the data type and parameter positioning must match (unless @SUM = variable is used).

DECLARE @TOTALCOST money
EXECUTE titles_sum 'The%', @TOTALCOST OUTPUT
IF @TOTALCOST < 200 
BEGIN
   PRINT ' '
   PRINT 'All of these titles can be purchased for less than $200.'
END
ELSE
   SELECT 'The total cost of these titles is $' 
         + RTRIM(CAST(@TOTALCOST AS varchar(20)))

Here is the result set:

Title Name                                                               
------------------------------------------------------------------------ 
The Busy Executive's Database Guide
The Gourmet Microwave
The Psychology of Computer Cooking

(3 row(s) affected)

Warning, null value eliminated from aggregate.
 
All of these titles can be purchased for less than $200.
E. Use an OUTPUT cursor parameter

OUTPUT cursor parameters are used to pass a cursor that is local to a stored procedure back to the calling batch, stored procedure, or trigger.

First, create the procedure that declares and then opens a cursor on the titles table:

USE pubs
IF EXISTS (SELECT name FROM sysobjects 
      WHERE name = 'titles_cursor' and type = 'P')
DROP PROCEDURE titles_cursor
GO
CREATE PROCEDURE titles_cursor @titles_cursor CURSOR VARYING OUTPUT
AS
SET @titles_cursor = CURSOR
FORWARD_ONLY STATIC FOR
SELECT *
FROM titles

OPEN @titles_cursor
GO

Next, execute a batch that declares a local cursor variable, executes the procedure to assign the cursor to the local variable, and then fetches the rows from the cursor.

USE pubs
GO
DECLARE @MyCursor CURSOR
EXEC titles_cursor @titles_cursor = @MyCursor OUTPUT
WHILE (@@FETCH_STATUS = 0)
BEGIN
   FETCH NEXT FROM @MyCursor
END
CLOSE @MyCursor
DEALLOCATE @MyCursor
GO
F. Use the WITH RECOMPILE option

The WITH RECOMPILE clause is helpful when the parameters supplied to the procedure will not be typical, and when a new execution plan should not be cached or stored in memory.

USE pubs
IF EXISTS (SELECT name FROM sysobjects
      WHERE name = 'titles_by_author' AND type = 'P')
   DROP PROCEDURE titles_by_author
GO
CREATE PROCEDURE titles_by_author @LNAME_PATTERN varchar(30) = '%'
WITH RECOMPILE
AS
SELECT RTRIM(au_fname) + ' ' + RTRIM(au_lname) AS 'Authors full name',
   title AS Title
FROM authors a INNER JOIN titleauthor ta 
   ON a.au_id = ta.au_id INNER JOIN titles t
   ON ta.title_id = t.title_id
WHERE au_lname LIKE @LNAME_PATTERN
GO
G. Use the WITH ENCRYPTION option

The WITH ENCRYPTION clause obfuscates the text of a stored procedure. This example creates an obfuscated procedure, uses the sp_helptext system stored procedure to get information on that obfuscated procedure, and then attempts to get information on that procedure directly from the syscomments table.

IF EXISTS (SELECT name FROM sysobjects
      WHERE name = 'encrypt_this' AND type = 'P')
   DROP PROCEDURE encrypt_this
GO
USE pubs
GO
CREATE PROCEDURE encrypt_this
WITH ENCRYPTION
AS
SELECT * 
FROM authors
GO

EXEC sp_helptext encrypt_this

Here is the result set:

The object's comments have been encrypted.

Next, select the identification number and text of the obfuscated stored procedure contents.

SELECT c.id, c.text 
FROM syscomments c INNER JOIN sysobjects o
   ON c.id = o.id
WHERE o.name = 'encrypt_this'

Here is the result set:

Note  The text column output is shown on a separate line. When executed, this information appears on the same line as the id column information.

id         text                                                        
---------- ------------------------------------------------------------
1413580074 ?????????????????????????????????e??????????????????????????????????????????????????????????????????????????

(1 row(s) affected)
H. Create a user-defined system stored procedure

This example creates a procedure to display all the tables and their corresponding indexes with a table name beginning with the string emp. If not specified, this procedure returns all tables (and indexes) with a table name beginning with sys.

IF EXISTS (SELECT name FROM sysobjects
      WHERE name = 'sp_showindexes' AND type = 'P')
   DROP PROCEDURE sp_showindexes
GO
USE master
GO
CREATE PROCEDURE sp_showindexes
   @TABLE varchar(30) = 'sys%'
AS 
SELECT o.name AS TABLE_NAME,
   i.name AS INDEX_NAME, 
   indid AS INDEX_ID
FROM sysindexes i INNER JOIN sysobjects o
   ON o.id = i.id 
WHERE o.name LIKE @TABLE
GO         
USE pubs
EXEC sp_showindexes 'emp%'
GO

Here is the result set:

TABLE_NAME       INDEX_NAME       INDEX_ID 
---------------- ---------------- ----------------
employee         employee_ind     1
employee         PK_emp_id        2

(2 row(s) affected)
I. Use deferred name resolution

This example shows a procedure that uses deferred name resolution. The stored procedure is created although the table that is referenced does not exist at compile time. The table must exist, however, at the time the procedure is executed.

USE master
GO
IF EXISTS (SELECT name FROM sysobjects
      WHERE name = 'proc1' AND type = 'P')
   DROP PROCEDURE proc1
GO
-- Create a procedure on a nonexistent table.
USE pubs
GO
CREATE PROCEDURE proc1
AS
   SELECT *
   FROM does_not_exist
GO  
-- This statement returns the text of the procedure proc1.
SELECT o.id, c.text
FROM sysobjects o INNER JOIN syscomments c 
   ON o.id = c.id
WHERE o.type = 'P' AND o.name = 'proc1'
GO
