How to test an stored procedure that calls another stored procedure

May 5, 2011 at 12:43 PM

Let's say WeeklySales sproc (stored procedure) calls in its implementation DailySales sproc.

If I create a test sproc SQLTest_WeeklySales that calls WeeklySales sproc I got an error because you cannot invoke an sproc that already invokes another sproc.

How do I test WeeklySales sproc ?

I have tested stored procedures that call other stored procedures and the only time I have hit a problem is if multiple stored procedures in the call stack are doing an INSERT INTO ... EXECUTE ... to put the results of a stored procedure into a table. That can't be nested. This is a limitation of SQL Server, not TST. In cases like that, I've had to rethink the problem and try to solve it in a different way.


Can you post the exact error message?

 I got error "Error: 8164, An INSERT EXEC statement cannot be nested." when excuting following code :
 WHILE @StartDay <= @EndDay
  INSERT INTO @WeeklySalesTable 
   EXEC [FCS].[dbo].[DailySales] @StartDay
  SET @StartDay = DATEADD(DAY,1,@StartDay)

Does [FCS].[dbo].[DailySales] do an INSERT INTO ... EXECUTE ... inside of it.Or does the code calling the code you posted do that? If so, that is you problem.


Does the code work fine outside of the TST testing?

 John thanks for your quick response and assistance.

[FCS].[dbo].[WeeklySales] does not do an INSERT INTO ... EXECUTE but the SQLTest_WeeklySales does as you can see below:

 -- This code is executed in SQLTest_WeeklySales stored procedure
 -- Store the actual data in #ExpectedResult
 INSERT INTO #ActualResult 
  EXEC [FCS].[dbo].[WeeklySales] @WeekEndingDate = '2011-05-03'

Do you know a workaround ?

Do you need to have [FCS].[dbo].[DailySales] as a stored procedure or can you do it in a table value function? Or can [FCS].[dbo].[DailySales] pass back a table parameter?

I found following workaround:

I replaced  

INSERT INTO #ActualResult
EXEC [FCS].[dbo].[WeeklySales] @WeekEndingDate = '2011-05-03'


 Insert Into #ActualResult
 FROM OPENROWSET('SQLNCLI', 'Server=7JFMMN1\POSExpress;Trusted_Connection=yes;',
 'EXEC [bos].[Central].[WeeklySales] @WeekEndingDate = ''2011-05-03''') AS a;

And it works !!
