srv_setcoldata

SQL Server 2000

Specifies the current address for a column's data.

Syntax

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 ODS Library uses to manage communication and data between the Open Data Services server 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 srv_senddone is called.

Returns

SUCCEED or FAIL.

Remarks

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.
