范例
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);?>
以上例程会输出：
--- 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]=>
