COMMIT TRANSACTION請求沒有相應的BEGIN TRANSACTION

這段代碼有什麼問題。COMMIT TRANSACTION請求沒有相應的BEGIN TRANSACTION

當過程中出現一些異常時，會發出此錯誤The COMMIT TRANSACTION request has no corresponding BEGIN TRANSACTION.。我該如何解決它？

BEGIN

    OPEN @Cursor_TradeFlow 
    FETCH NEXT FROM @Cursor_TradeFlow INTO @Id, @Month, @Year, @CountryofExport, @CountryofOrigin, @HSCode,@Quantity, @Unit, @CustomValue, @Type

請出示所有相關的代碼。你的代碼不包含'COMMIT TRANSACTION' –

你已經在幾個地方使用了Try/Catch，有什麼理由不使用它而不是@@ Error？例如，圍繞整個循環進行的全局try/catch（而不是當前的@@錯誤檢查）對於您的問題將是一個簡單的解決方案 - 任何意外問題都會使整個事情回滾。 – Tao

爲什麼你使用遊標？ – HLGEM

有：

IF @@ERROR <> 0 
BEGIN 
    ROLLBACK 
END

遊標循環中是一個不好的徵兆 - 你回滾事務，然後繼續進入下一個迭代。當循環最終完成時，您嘗試提交併且 - 糟糕 - 不再有任何打開的事務，並且回滾之後的每個操作都已保留。

您可能想要在回滾後使用GOTO退出循環，或者以不同的方式處理錯誤。說出最好的策略可能太難了。

你可以使用命名事務：

- 在一開始大交易
BEGIN TRANSACTION BIG_TRANSACTION
-- your code here 

-- a transaction for each fetched item 
BEGIN TRANSACTION FETCH_TRANSACTION 
-- your code here 
if OK 
    COMMIT TRANSACTION FETCH_TRANSACTION 
else 
    ROLLBACK TRANSACTION FETCH_TRANSACTION 
COMMIT/ROLLBACK TRANSACTION BIG_TRANSACTION
