Specifies the current data length in bytes of a variable-length column or a column that allows NULL values.
구문
int srv_setcollen (
SRV_PROC *
srvproc
,
int
column
,
int
len
);
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 for which the data length is being specified. Columns are numbered beginning with 1.
- len
Indicates the length, in bytes, of the column data. A length of 0 means the column data value is null.
Returns
SUCCEED or FAIL.
주의
Each column of the row must first be defined with srv_describe. The column data length is set by the last call to srv_describe or srv_setcollen. If variable-length data (null-terminated data) changes for a row, srv_setcollen must be used to set it to the new length before calling srv_sendrow. For a column that allows null values, srv_describe must have been called with desttype set to a data type that allows nulls (like SRVINTN) and null data is specified by calling srv_setcollen with len set to 0. Zero length data cannot be specified using the Extended Stored Procedure API.
Note that when the data type of the column is variable-length, len is not checked. This function returns FAIL if called for a fixed-length column.

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. |
