bool cubrid_seq_drop(resource $conn_identifier, string $oid, string $attr_name, int $index)

  • conn_identifier : Connection identifier
  • oid : OID of the desired instance
  • attr_name : Name of the desired attribute of the instance
  • index : Index of the element to be dropped. The default value is 1.

Example

<?php

$conn = cubrid_connect("localhost", 33000, "demodb");

 

@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);

?>

 

The above example will output:

 

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"

}
