I have an automated service that runs 3 stored procedure namely sp_1, sp_2, sp_3. When I was running SQL Trace, it displayed the following results
EXEC sp_1
EXEC sp_1
EXEC sp_2
EXEC sp_2
EXEC sp_4
EXEC sp_4
EXEC sp_2
EXEC sp_2
I don't know where the sp_4 came from. It doesn't exist in my automated service nor database.
