@@CONNECTIONS (Transact-SQL)

SQL Server 2005

傳回 SQL Server 上次啟動之後所嘗試的連接次數，成功和失敗都包括在內。

主題連結圖示 Transact-SQL 語法慣例

複製 

@@CONNECTIONS

integer

連接次數並不等於使用者數目。例如，當沒有觀察連接的使用者時，應用程式仍可以開啟多個通往 SQL Server 的連接。

若要顯示包含多項 SQL Server 統計資料的報表，其中包括連接嘗試次數，請執行 sp_monitor。

@@MAX_CONNECTIONS 是伺服器能夠同時接受的最大連接數目。@@CONNECTIONS 會隨著每次的登入嘗試而遞增，因此，@@CONNECTIONS 可能大於 @@MAX_CONNECTIONS。

下列範例會顯示傳回迄今 (到目前的日期和時間為止) 的登入嘗試次數。

SELECT GETDATE() AS 'Today''s Date and Time', 
@@CONNECTIONS AS 'Login Attempts'
