sp_helpconstraint (Transact-SQL)

SQL Server 2005

Updated: 14 April 2006

Returns a list of all constraint types, their user-defined or system-supplied name, the columns on which they have been defined, and the expression that defines the constraint (for DEFAULT and CHECK constraints only).

Topic link icon Transact-SQL Syntax Conventions


sp_helpconstraint [ @objname = ] 'table' 
     [ , [ @nomsg = ] 'no_message' ]

[ @objname = ] 'table': Is the table about which constraint information is returned. The table specified must be local to the current database. table is nvarchar(776), with no default.

[ @nomsg =] 'no_message': Is an optional parameter that prints the table name. no_message is varchar(5), with a default of msg. nomsg suppresses the printing.

Return Code Values

0 (success) or 1 (failure)

sp_helpconstraint displays a descending indexed column if it participated in primary keys. The descending indexed column will be listed in the result set with a minus sign (-) following its name. The default, an ascending indexed column, will be listed by its name alone.

Executing sp_help table reports all information about the specified table. To see only the constraint information, use sp_helpconstraint.

Requires membership in the public role.

The following example shows all constraints for the Product table.

USE AdventureWorks;
GO
EXEC sp_helpconstraint 'Production.Product';
