SQL查詢幫助：從存儲過程插入到臨時表中時出錯

Question

我有一個存儲過程，它輸出一列。它運行沒有問題。

exec dbo.sp_SelectAlignmentSubset 
    @AlnID 
    ,@ParentTaxID 
    ,@SeqTypeID 
    ,@LocationID 
    ,@SubsetSize 
    ,@SimilarityThreshold 
    ,@SimilarityTable 
    ,@AnchorSeqID 

但是當我插入的過程輸出到一個臨時表，

create table #resultSeqIDs 
(
    SeqID int not null 
) 

Insert into #resultSeqIDs 
exec dbo.sp_SelectAlignmentSubset 
    @AlnID 
    ,@ParentTaxID 
    ,@SeqTypeID 
    ,@LocationID 
    ,@SubsetSize 
    ,@SimilarityThreshold 
    ,@SimilarityTable 
    ,@AnchorSeqID 

錯誤提前跳出"The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction."

感謝。

程序的查詢是在這裏：

Alter Proc dbo.sp_SelectAlignmentSubset 
    @AlnID int, 
    @ParentTaxID int, 
    @SeqTypeID int, 
    @LocationID int, 
    @SubsetSize int, 
    @SimilarityThreshold float, 
    @SimilarityTable nvarchar(255), 
    @AnchorSeqID int = null 
As 
    declare @sql nvarchar(4000), @param nvarchar(2000), @subsetActualSize int, @lastSeqID int, @meanSimilarity float

如果程序運行正常，但插入一條記錄到一個臨時表沒有，那麼我會檢查用戶的角色運行記錄插入。該錯誤消息指出只讀訪問。

Answer 2

你在你的存儲過程的結束做以下語句：

select SeqID from #Subset 

drop table #Subset 

嘗試改變，要

Insert Into #resultSeqIDs select SeqID from #Subset 
drop table #Subset 

然後從那裏執行SQL語句的INSERT命令。

由於您的#resultSeqIDs臨時表仍將處於作用域中，它將保存您需要的所有值。

如果您使用的是SQL Server 2008及更高版本，則可以返回一個表變量 - 一個比#temp表更好的替代方法。
