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 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')");

cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(2, {4,5,7}, {44,55,66,666}, 'b')");

 

$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);

 

cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);

$oid = cubrid_current_oid($req);

 

printf("--- Before Drop: --- ");

$attr = cubrid_get($conn, $oid);

var_dump($attr);

 

if (cubrid_drop($conn, $oid)) {

    cubrid_commit($conn);

} else {

    cubrid_rollback($conn);

}

 

cubrid_close_request($req);

 

$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);

 

cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);

$oid = cubrid_current_oid($req);

 

printf(" --- After Drop: --- ");

$attr = cubrid_get($conn, $oid);

var_dump($attr);

 

cubrid_close_request($req);

cubrid_disconnect($conn);

?>

 

The above example will output:

 

--- Before Drop: ---

array(4) {

  ["a"]=>

  string(1) "1"

  ["b"]=>

  array(3) {

    [0]=>

    string(1) "1"

    [1]=>

    string(1) "2"

    [2]=>

    string(1) "3"

  }

  ["c"]=>

  array(4) {

    [0]=>

    string(2) "11"

    [1]=>

    string(2) "22"

    [2]=>

    string(2) "33"

    [3]=>

    string(3) "333"

  }

  ["d"]=>

  string(10) "a         "

}

 

--- After Drop: ---

array(4) {

  ["a"]=>

  string(1) "2"

  ["b"]=>

  array(3) {

    [0]=>

    string(1) "4"

    [1]=>

    string(1) "5"

    [2]=>

    string(1) "7"

  }

  ["c"]=>

  array(4) {

    [0]=>

    string(2) "44"

    [1]=>

    string(2) "55"

    [2]=>

    string(2) "66"

    [3]=>

    string(3) "666"

  }

  ["d"]=>

  string(10) "b         "

}
