srv_setutype (Extended Stored Procedure API)
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use CLR integration instead.
Sets the user-defined data type for a column in a row.
int srv_setutype ( SRV_PROC * srvproc , int column , DBINT user_type );
Is a pointer to the SRV_PROC structure that is the handle for a particular client connection. The structure contains information the Extended Stored Procedure API library uses to manage communication and data between the application and the client.
Indicates which column to set. Columns are numbered beginning with 1.
Specifies the user-defined data type code.
SUCCEED or FAIL. Returns FAIL if the column does not exist.
A column has two data types: its actual data type and its user-defined data type. The user-defined data type is used by Microsoft SQL Server to store the actual user-defined data type of the column, if any, and column description information, such as nullability and updatability, for the column.
The srv_setutype function can be called any time that column has been defined with srv_describe and before the last row has been sent.
You should thoroughly review the source code of extended stored procedures, and you should test the compiled DLLs before you install them on a production server. For information about security review and testing, see this Microsoft Web site.
