HAS_DBACCESS (Transact-SQL)

SQL Server 2005

傳回使用者是否具有指定資料庫存取權的相關資訊。

主題連結圖示 Transact-SQL 語法慣例

複製 

HAS_DBACCESS ( 'database_name' )
'database_name'

這是使用者需要存取資訊的資料庫名稱。database_name 是 sysname。

如果使用者有資料庫的存取權，HAS_DBACCESS 會傳回 1；如果沒有存取權，則會傳回 0；如果資料庫名稱無效，則會傳回 NULL。

需要 public 角色中的成員資格。

下列範例會測試目前使用者是否具有 AdventureWorks 資料庫的存取權。

複製 
SELECT HAS_DBACCESS('AdventureWorks');
