@@TEXTSIZE (Transact-SQL)

SQL Server 2005

傳回 SET 陳述式的 TEXTSIZE 選項的目前值。這個值可以指定 SELECT 陳述式傳回的 varchar(max)、nvarchar(max)、varbinary(max)、text 或 image 資料的最大長度 (以位元組為單位)。

主題連結圖示 Transact-SQL 語法慣例

複製 

@@TEXTSIZE

integer

預設大小為 4096 位元組。@@TEXTSIZE 傳回的大小上限是 2^31-1 位元組。

下列範例會利用 SELECT 來顯示在被 SET TEXTSIZE 陳述式變更前後的 @@TEXTSIZE 值。

複製 
SELECT @@TEXTSIZE AS 'Text Size'
SET TEXTSIZE 2048
SELECT @@TEXTSIZE AS 'Text Size'

以下為結果集：
