srv_setutype (Extended Stored Procedure API)

Important

This feature will be removed in a future version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible. Use CLR integration instead.

Sets the user-defined data type for a column in a row.

Syntax


int srv_setutype (
SRV_PROC *
srvproc
,
int 
column
, 
DBINT
user_type 
);

Arguments

  • srvproc
    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.

  • column
    Indicates which column to set. Columns are numbered beginning with 1.

  • user_type
    Specifies the user-defined data type code.

Returns

SUCCEED or FAIL. Returns FAIL if the column does not exist.

Remarks

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.

Security noteSecurity Note

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.
