ROUTINES

SQL Server 2000

Contains one row for each stored procedure and function accessible to the current user in the current database. The columns that describe the return value apply only to functions. For stored procedures, these columns will be NULL.

The INFORMATION_SCHEMA.ROUTINES view is based on the sysobjects and syscolumns system tables.

To retrieve information from these views, specify the fully qualified name of INFORMATION_SCHEMA view_name.

Note  The ROUTINE_DEFINITION column contains the source statements that created the function, stored procedure, or trigger. These source statements are likely to contain embedded carriage returns. If you are returning this column to an application that is displaying the results in a text format, the embedded carriage returns in the ROUTINE_DEFINITION results may affect the formatting of the overall result set. If you select the ROUTINE_DEFINITION column, you must adjust for the embedded carriage returns; for example, by returning the result set into a grid or returning ROUTINE_DEFINITION into its own text box.
