例1 cubrid_col_size() 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')");
$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);
cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);
$oid = cubrid_current_oid($req);
$attr = cubrid_col_get($conn, $oid, "b");
var_dump($attr);
$size = cubrid_col_size($conn, $oid, "b");
var_dump($size);
cubrid_close_request($req);
cubrid_disconnect($conn);
?>
上の例の出力は以下となります。
array(3) { [0]=> string(1) "1" [1]=> string(1) "2" [2]=> string(1) "3" } int(3)
