SSIS执行SQL任务有效，但在执行报告中显示错误消息

Question

My Execute SQL Task executes a stored procedure. If it gets some records, then proceeds to a task to create a report. Otherwise, it goes to a script task to send out an email. The ResultSet is set to "Single row".

Everything works as expected. However, when stored procedure does not return any rows, it still sends out an email, but creates a failed message in SQL Execution report. The error message states:

An error occurred while assigning a value to variable "Variable": "Single Row result set is specified, but no rows were returned."

I cannot modify my stored procedure. What are my options to "fix" this error. (My package runs as expected.)

Answer 1

You have to add some validation to your Execute SQL Task to avoid Empty ResultSets

1. Insert result into a Temp Table
2. Check If the Temp Table contains Rows

3. If not Select an non significant Row

    CREATE #TempTable (Column0 Varchar(50), Column1 varchar(50), ....) INSERT INTO #TempTable EXEC Proc DECLARE @intCount INT SELECT @intCount = COUNT(*) FROM #TempTable IF @intCount > 0 SELECT TOP 1 * FROM #TempTable ELSE SELECT 0 

4. Add An expression on The Send Mail Task ( If Not Empty Row --> Send Mail )
