這裡其實並不需要其它的什麼函數來支持，只需要使用MySQL提供的一些SQL語句就可以了。
這裡為了簡單起見，以MySQL的系統表USER為例，取出SELECT_PRIV這一列的所有可能值。
方法：SHOW COLUMNS FROM table_name LIKE enum_column_name
小寫的部分需要根據你的情況改變。
程序：
//By SonyMusic([email protected])
//HomePage(PHPcode.yeah.Net)
$connect_hostname="localhost";
$dbn下面是利用SQL語句創建數據庫、表、存儲過程、視圖、索引、規則、修改表、查看數據等的方法。所要增加的控件如下：
