SYMPTOMS
========

The SQL Debugger may fail to stop at breakpoints that are set after a call to a
stored procedure from a database (other than the current one) is executed.

CAUSE
=====

The call to the stored procedure in the secondary database changes the context
of SQL Server to that database.

The SQL Debugger cannot find breakpoints that were set in the context of the
previous database and fails to break on them.

RESOLUTION
==========

Work around this by placing a call to a stored procedure that resides in the
same database as the stored procedure you were initially debugging.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This problem was corrected in Visual C++ version 6.0
for Windows.

Sample Code
-----------

     /* Sample SP which shows the problem */ 
     Create Procedure sp_MySP
     As
     SELECT * FROM employee

     /* Breakpoints set after this call will not be hit */ 
     EXEC OtherDB.dbo.sp_SomeSP

     SELECT * FROM Authors

     RETURN (0)

     -----------
     /* Sample SP with a workaround */ 
     /* Add one line of code */ 

     Create Procedure sp_MySP
     As
     SELECT * FROM EMPLOYEE

     EXEC OtherDB.dbo.sp_SomeSP

     /* This causes the database context to be changed back to original */ 
     /* Breakpoints will now be hit */ 
     EXEC sp_MySP2

     SELECT * FROM Authors

     RETURN (0)

     /* Stored procedure called from above */ 

     Create Procedure sp_MySP2
     As
     RETURN (0)
