cubrid_col_get

(PECL CUBRID >= 8.3.0)

cubrid_col_getGet contents of collection type column using OID

说明

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

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)
