(PECL CUBRID >= 8.3.0)

cubrid_col_getGet 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

Example #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)
