SQLTablePrivileges Function

Conformance

Version Introduced: ODBC 1.0 Standards Compliance: ODBC

Summary

SQLTablePrivileges returns a list of tables and the privileges associated with each table. The driver returns the information as a result set on the specified statement.


SQLRETURN SQLTablePrivileges(
     SQLHSTMT      StatementHandle,
     SQLCHAR *     CatalogName,
     SQLSMALLINT   NameLength1,
     SQLCHAR *     SchemaName,
     SQLSMALLINT   NameLength2,
     SQLCHAR *     TableName,
     SQLSMALLINT   NameLength3);

StatementHandle

[Input] Statement handle.

CatalogName

[Input] Table catalog. If a driver supports catalogs for some tables but not for others, such as when the driver retrieves data from different DBMSs, an empty string ("") denotes those tables that do not have catalogs. CatalogName cannot contain a string search pattern.

If the SQL_ATTR_METADATA_ID statement attribute is set to SQL_TRUE, CatalogName is treated as an identifier and its case is not significant. If it is SQL_FALSE, CatalogName is an ordinary argument; it is treated literally, and its case is significant. For more information, see Arguments in Catalog Functions.

NameLength1

[Input] Length in characters of *CatalogName.

SchemaName

[Input] String search pattern for schema names. If a driver supports schemas for some tables but not for others, such as when the driver retrieves data from different DBMSs, an empty string ("") denotes those tables that do not have schemas.

If the SQL_ATTR_METADATA_ID statement attribute is set to SQL_TRUE, SchemaName is treated as an identifier and its case is not significant. If it is SQL_FALSE, SchemaName is a pattern value argument; it is treated literally, and its case is significant.

NameLength2

[Input] Length in characters of *SchemaName.

TableName

[Input] String search pattern for table names.

If the SQL_ATTR_METADATA_ID statement attribute is set to SQL_TRUE, TableName is treated as an identifier and its case is not significant. If it is SQL_FALSE, TableName is a pattern value argument; it is treated literally, and its case is significant.

NameLength3

[Input] Length in characters of *TableName.

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_STILL_EXECUTING, SQL_ERROR, or SQL_INVALID_HANDLE.

When SQLTablePrivileges returns SQL_ERROR or SQL_SUCCESS_WITH_INFO, an associated SQLSTATE value may be obtained by calling SQLGetDiagRec with a HandleType of SQL_HANDLE_STMT and a Handle of StatementHandle. The following table lists the SQLSTATE values commonly returned by SQLTablePrivileges and explains each one in the context of this function; the notation "(DM)" precedes the descriptions of SQLSTATEs returned by the Driver Manager. The return code associated with each SQLSTATE value is SQL_ERROR, unless noted otherwise.

SQLSTATE

Error

Description

01000

General warning

Driver-specific informational message. (Function returns SQL_SUCCESS_WITH_INFO.)

08S01

Communication link failure

The communication link between the driver and the data source to which the driver was connected failed before the function completed processing.

24000

Invalid cursor state

A cursor was open on the StatementHandle, and SQLFetch or SQLFetchScroll had been called. This error is returned by the Driver Manager if SQLFetch or SQLFetchScroll has not returned SQL_NO_DATA and is returned by the driver if SQLFetch or SQLFetchScroll has returned SQL_NO_DATA.

A cursor was open on the StatementHandle, but SQLFetch or SQLFetchScroll had not been called.

40001

Serialization failure

The transaction was rolled back due to a resource deadlock with another transaction.

40003

Statement completion unknown

The associated connection failed during the execution of this function, and the state of the transaction cannot be determined.

HY000

General error

An error occurred for which there was no specific SQLSTATE and for which no implementation-specific SQLSTATE was defined. The error message returned by SQLGetDiagRec in the *MessageText buffer describes the error and its cause.

HY001

Memory allocation error

The driver was unable to allocate memory required to support execution or completion of the function.

HY008

Operation canceled

Asynchronous processing was enabled for the StatementHandle. The SQLTablePrivileges function was called, and before it completed execution, SQLCancel or SQLCancelHandle was called on the StatementHandle. Then the SQLTablePrivileges function was called again on the StatementHandle.

The SQLTablePrivileges function was called, and before it completed execution, SQLCancel or SQLCancelHandle was called on the StatementHandle from a different thread in a multithread application.

HY009

Invalid use of null pointer

The SQL_ATTR_METADATA_ID statement attribute was set to SQL_TRUE, the CatalogName argument was a null pointer, and the SQL_CATALOG_NAME InfoType returns that catalog names are supported.

(DM) The SQL_ATTR_METADATA_ID statement attribute was set to SQL_TRUE, and the SchemaName or TableName argument was a null pointer.

HY010

Function sequence error

(DM) An asynchronously executing function was called for the connection handle that is associated with the StatementHandle. This asynchronous function was still executing when the SQLTablePrivileges function was called.

(DM) SQLExecute, SQLExecDirect, or SQLMoreResults was called for the StatementHandle and returned SQL_PARAM_DATA_AVAILABLE. This function was called before data was retrieved for all streamed parameters.

(DM) An asynchronously executing function (not this one) was called for the StatementHandle and was still executing when this function was called.

(DM) SQLExecute, SQLExecDirect, SQLBulkOperations, or SQLSetPos was called for the StatementHandle and returned SQL_NEED_DATA. This function was called before data was sent for all data-at-execution parameters or columns.

HY013

Memory management error

The function call could not be processed because the underlying memory objects could not be accessed, possibly because of low memory conditions.

HY090

Invalid string or buffer length

(DM) The value of one of the name length arguments was less than 0 but not equal to SQL_NTS.

The value of one of the name length arguments exceeded the maximum length value for the corresponding qualifier or name.

HY117

Connection is suspended due to unknown transaction state. Only disconnect and read-only functions are allowed.

(DM) For more information about the suspended state, see SQLEndTran Function.

HYC00

Optional feature not implemented

A catalog was specified, and the driver or data source does not support catalogs.

A schema was specified, and the driver or data source does not support schemas.

A string search pattern was specified for the table schema, table name, or column name, and the data source does not support search patterns for one or more of those arguments.

The combination of the current settings of the SQL_ATTR_CONCURRENCY and SQL_ATTR_CURSOR_TYPE statement attributes was not supported by the driver or data source.

The SQL_ATTR_USE_BOOKMARKS statement attribute was set to SQL_UB_VARIABLE, and the SQL_ATTR_CURSOR_TYPE statement attribute was set to a cursor type for which the driver does not support bookmarks.

HYT00

Timeout expired

The query timeout period expired before the data source returned the result set. The timeout period is set through SQLSetStmtAttr, SQL_ATTR_QUERY_TIMEOUT.

HYT01

Connection timeout expired

The connection timeout period expired before the data source responded to the request. The connection timeout period is set through SQLSetConnectAttr, SQL_ATTR_CONNECTION_TIMEOUT.

IM001

Driver does not support this function

(DM) The driver associated with the StatementHandle does not support the function.

IM017

Polling is disabled in asynchronous notification mode

Whenever the notification model is used, polling is disabled.

IM018

SQLCompleteAsync has not been called to complete the previous asynchronous operation on this handle.

If the previous function call on the handle returns SQL_STILL_EXECUTING and if notification mode is enabled, SQLCompleteAsync must be called on the handle to do post-processing and complete the operation.

The SchemaName and TableName arguments accept search patterns. For more information about valid search patterns, see Pattern Value Arguments.

SQLTablePrivileges returns the results as a standard result set, ordered by TABLE_CAT, TABLE_SCHEM, TABLE_NAME, PRIVILEGE, and GRANTEE.

To determine the actual lengths of the TABLE_CAT, TABLE_SCHEM, and TABLE_NAME columns, an application can call SQLGetInfo with the SQL_MAX_CATALOG_NAME_LEN, SQL_MAX_SCHEMA_NAME_LEN, and SQL_MAX_TABLE_NAME_LEN options.

Note Note

For more information about the general use, arguments, and returned data of ODBC catalog functions, see Catalog Functions.

The following columns have been renamed for ODBC 3.x. The column name changes do not affect backward compatibility because applications bind by column number.

ODBC 2.0 column

ODBC 3.x column

TABLE_QUALIFIER

TABLE_CAT

TABLE_OWNER

TABLE_SCHEM

The following table lists the columns in the result set. Additional columns beyond column 7 (IS_GRANTABLE) can be defined by the driver. An application should gain access to driver-specific columns by counting down from the end of the result set rather than specifying an explicit ordinal position. For more information, see Data Returned by Catalog Functions.

Column name

Column number

Data type

Comments

TABLE_CAT (ODBC 1.0)

1

Varchar

Catalog name; NULL if not applicable to the data source. If a driver supports catalogs for some tables but not for others, such as when the driver retrieves data from different DBMSs, it returns an empty string ("") for those tables that do not have catalogs.

TABLE_SCHEM (ODBC 1.0)

2

Varchar

Schema name; NULL if not applicable to the data source. If a driver supports schemas for some tables but not for others, such as when the driver retrieves data from different DBMSs, it returns an empty string ("") for those tables that do not have schemas.

TABLE_NAME (ODBC 1.0)

3

Varchar not NULL

Table name.

GRANTOR (ODBC 1.0)

4

Varchar

Name of the user who granted the privilege; NULL if not applicable to the data source.

For all rows in which the value in the GRANTEE column is the owner of the object, the GRANTOR column will be "_SYSTEM".

GRANTEE (ODBC 1.0)

5

Varchar not NULL

Name of the user to whom the privilege was granted.

PRIVILEGE (ODBC 1.0)

6

Varchar not NULL

The table privilege. May be one of the following or a data source–specific privilege.

SELECT: The grantee is permitted to retrieve data for one or more columns of the table.

INSERT: The grantee is permitted to insert new rows containing data for one or more columns into the table.

UPDATE: The grantee is permitted to update the data in one or more columns of the table.

DELETE: The grantee is permitted to delete rows of data from the table.

REFERENCES: The grantee is permitted to refer to one or more columns of the table within a constraint (for example, a unique, referential, or table check constraint).

The scope of action permitted the grantee by a given table privilege is data source–dependent. For example, the UPDATE privilege might permit the grantee to update all columns in a table on one data source and only those columns for which the grantor has the UPDATE privilege on another data source.

IS_GRANTABLE (ODBC 1.0)

7

Varchar

Indicates whether the grantee is permitted to grant the privilege to other users; "YES", "NO", or NULL if unknown or not applicable to the data source.

A privilege is either grantable or not grantable but not both. The result set returned by SQLColumnPrivileges will never contain two rows for which all columns except the IS_GRANTABLE column contain the same value.

For a code example of a similar function, see SQLColumns.
