Question

我有一个输出列的存储过程。它运行没有问题。

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

但是当我将过程输出插入临时表时，

create table #resultSeqIDs
(
    SeqID int not null
)

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

错误弹出"The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction."

提前致谢。

程序的查询在这里：

Answer 1

您在存储过程结束时正在执行以下语句：

select SeqID from #Subset

drop table #Subset

尝试将其更改为

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

然后从执行语句的地方删除INSERT命令。

由于#resultSeqIDs Temp表仍在范围内，因此它将包含您需要的所有值。

如果您使用的是SQL Server 2008及更高版本，则可以返回表变量 - 这是#temp表的一个更好的替代方法。

如果程序运行正常，但是没有将记录插入临时表，那么我将检查运行记录插入的用户的角色。错误消息指出只读访问。
