### 示例

示例 #1 List Privileges for a Column

`<?php
$conn = odbc_connect($dsn, $user, $pass);
$privileges = odbc_columnprivileges($conn, 'TutorialDB', 'dbo', 'test', 'id');
while (($row = odbc_fetch_array($privileges))) {
print_r($row);
break; // further rows omitted for brevity
}
?>`

以上示例的输出类似于：

    Array
    (
        [TABLE_CAT] => TutorialDB
        [TABLE_SCHEM] => dbo
        [TABLE_NAME] => test
        [COLUMN_NAME] => id
        [GRANTOR] => dbo
        [GRANTEE] => dbo
        [PRIVILEGE] => INSERT
        [IS_GRANTABLE] => YES
    )
