如何獲取SQL Server 2008查詢中的行數

Question

如何獲取SQL查詢的行數？

我嘗試這樣做：

SET @Records = count(*) SELECT * FROM [INVENTORY].[TBL_RECEIPTS] 
       WHERE Field_Tag = '1234' 

但它給一，什麼是錯的與上面的代碼？

其實沒有行，它應該給輸出0

當我執行這個

SELECT * FROM [INVENTORY].[TBL_RECEIPTS] 
WHERE Field_Tag = '1234' 

它給結果0

Answer 1

使用

SET @Records = (SELECT count(*) 
        FROM [INVENTORY].[TBL_RECEIPTS] 
       WHERE Field_Tag = '1234') 

Answer 2

SELECT @Records = COUNT(*) FROM INVENTORY.TBL_RECEIPTS 
    WHERE Field_Tag = '1234'; 

Answer 3

做這些 - 要麼sh烏爾德工作，但我更喜歡第二個代碼

SET @Records = (SELECT Count(*) FROM [INVENTORY].[TBL_RECEIPTS] 
       WHERE Field_Tag = '1234') 

OR

SELECT @Records = Count(*) FROM [INVENTORY].[TBL_RECEIPTS] 
       WHERE Field_Tag = '1234'
