Example #1 cubrid_lock_write() example
<?php$conn = cubrid_connect("localhost", 33000, "demodb", "dba");@cubrid_execute($conn, "DROP TABLE foo");cubrid_execute($conn, "CREATE TABLE foo(a int AUTO_INCREMENT, b set(int), c list(int), d char(10))");cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(1, {1,2,3}, {11,22,33,333}, 'a')");cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(2, {4,5,7}, {44,55,66,666}, 'b')");$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);$oid = cubrid_current_oid($req);cubrid_lock_write($conn, $oid);$attr = cubrid_col_get($conn, $oid, "b");var_dump($attr);cubrid_put($conn, $oid, "b", array(2, 4, 8));$attr = cubrid_col_get($conn, $oid, "b");var_dump($attr);cubrid_close_request($req);cubrid_disconnect($conn);?>
