dbQueryGetLastErrorNum#

Purpose#

Returns error information about the last error that occurred (if any) with the last executed query.

Format#

err_num = dbQueryGetLastErrorNum()#

Returns:: err_num (scalar) – number of last error.

Remarks#

Because a failed query will not have a valid handle (id), this function retrieves stored error information about the last executed query.

Examples#

// Execute a query
qid = dbExecQuery(db_id, "SELECT * FROM nonexistent_table");

// Check for a query error
err_num = dbQueryGetLastErrorNum();

if err_num != 0;
    print (err_num);
endif;
