cubrid_col_get — Get contents of collection type column using OID
$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.
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.
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.
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)
