cubrid_col_get — Get contents of collection type column using OID

说明

cubrid_col_get(resource $conn_identifier, string $oid, string $attr_name): array

The cubrid_col_get() function is used to get contents of the elements of the collection type (set, multiset, sequence) attribute you requested as an array.

参数

conn_identifier: Connection identifier.
oid: OID of the instance that you want to read.
attr_name: Attribute name that you want to read from the instance.

返回值

Array (0-based numerical array) containing the elements you requested, when process is successful;

false (to distinguish the error from the situation of attribute having empty collection or NULL, in case of error, a warning message is shown; in such case you can check the error by using cubrid_error_code()), when process is unsuccessful.

范例

示例 #1 cubrid_col_get() 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);
?>

以上例程会输出：

array(3) {
  [0]=>
  string(1) "1"
  [1]=>
  string(1) "2"
  [2]=>
  string(1) "3"
}
int(3)
