Example #1 cubrid_drop 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: ---\n");
$attr = cubrid_get($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("\n--- After Drop: ---\n");
$attr = cubrid_get($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         "
}
