SQL查询帮助：从存储过程插入到临时表中时出错

Question

我有一个存储过程，它输出一列。它运行没有问题。

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

但是当我插入的过程输出到一个临时表，

create table #resultSeqIDs 
(
    SeqID int not null 
) 

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

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

感谢。

程序的查询是在这里：

Alter Proc dbo.sp_SelectAlignmentSubset 
    @AlnID int, 
    @ParentTaxID int, 
    @SeqTypeID int, 
    @LocationID int,

    @SimilarityThreshold float, 
    @SimilarityTable nvarchar(255), 
    @AnchorSeqID int = null

    declare @sql nvarchar(4000), @param nvarchar(2000), @subsetActualSize int, @lastSeqID int, @meanSimilarity float

如果程序运行正常，但插入一条记录到一个临时表没有，那么我会检查用户的角色运行记录插入。该错误消息指出只读访问。

Answer 2

你在你的存储过程的结束做以下语句：

select SeqID from #Subset 

drop table #Subset 

尝试改变，要

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

然后从那里执行SQL语句的INSERT命令。

由于您的#resultSeqIDs临时表仍将处于作用域中，它将保存您需要的所有值。

如果您使用的是SQL Server 2008及更高版本，则可以返回一个表变量 - 一个比#temp表更好的替代方法。
