schema: The schema ('owner' in ODBC 2 parlance). 此参数接受下列查询模式："%" 来匹配零到多个字符，"_" 来匹配单个字符。
table_name: The table name. 此参数接受下列查询模式："%" 来匹配零到多个字符，"_" 来匹配单个字符。
column_name: The column name. 此参数接受下列查询模式："%" 来匹配零到多个字符，"_" 来匹配单个字符。

返回值

The result set has the following columns:

TABLE_CAT
TABLE_SCHEM
TABLE_NAME
COLUMN_NAME
GRANTOR
GRANTEE
PRIVILEGE
IS_GRANTABLE

Drivers can report additional columns.

范例

Example #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
}
?>

以上例程的输出类似于：

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