Example #1 cubrid_seq_drop() 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 sequence(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 , "c" );
var_dump ( $attr );
cubrid_seq_drop ( $conn , $oid , "c" , 4 );
$attr = cubrid_col_get ( $conn , $oid , "c" );
var_dump ( $attr );
cubrid_close_request ( $req );
cubrid_disconnect ( $conn );
?>
以上例程会输出:
array(4) { [0]=> string(2) "11" [1]=> string(2) "22" [2]=> string(2) "33" [3]=> string(3) "333" } array(3) { [0]=> string(2) "11" [1]=> string(2) "22" [2]=> string(2) "33" }
