srv_setcoldata (Extended Stored Procedure API)

重要事項：
未來的 Microsoft SQL Server 發行版本將不再提供此功能。請勿在新的開發工作中使用此功能，並且儘速修改使用此功能的應用程式。 Use CLR integration instead.

Specifies the current address for a column's data.

語法

int srv_setcoldata (
SRV_PROC *
srvproc
,
int 
column
,
void *
data 
);

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 the number of the column the address is being specified for. Columns are numbered beginning with 1.

• data
  Is a pointer for a column's data. Memory allocated for data should not be freed until the column data is replaced by another call to srv_setcoldata, or until srv_senddone is called.

Returns

SUCCEED or FAIL.

備註

Each column of the row must be defined first with srv_describe. Column data addresses are initially set with srv_describe. If the address of the column data changes, srv_setcoldata must be called to specify the new address of the data and srv_setcoldata must be called separately for each changed column.

Null data is represented by setting the column's length to 0 with srv_setcollen. The data address is then ignored.

安全性注意事項：
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.
