Hello all!

I've been assigned to deconstruct and document a rather large Stored Procedure (SQL 2008). This procedure simply declared about a dozen of other procedures with I will need to anaylize and document. I'm coming into an environment where a handleful of other developers wrote, programmed, and left and not a damn thing was documented. So, I along with the help of someone else, are decontructing it all and documenting it.

Anyway, the SP starts off like this:


ALTER PROCEDURE [dbo].[The Name of this very SP]
(@Dummy varchar(20))
as

Exec [SP #1] 1
Exec [SP #2] 1

...and so on.

I have two questions.

1) What does @Dummy do?

2) What do the "1" indicate after firing off each SP?

Thanks in advance for your help!!

Can't tell for sure, since you only posted part of the code, but the @Dummy parameter does nothing in the code you posted. Perhaps it's used elsewhere.

The 1 after the procedure calls is a parameter value, like
exec sp_help 'Test'

Thanks for helping. Here is is all cleaned up:


USE [Database name]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[THIS SP NAME](
@Dummy varchar(20)
)
as


Exec [SP #1] 1
Exec [SP #2]
Exec [SP #3] 1
Exec [SP #4] 1

...an so on...


That's it.


If I peak into SP #1, I see this:


ALTER PROCEDURE [dbo].[SP #1](
@Test int
)
AS
Truncate table [Table Name]


Thoughts?

The parameters are meaningless and never used.

Total WAG...but I have seen things like this where the developers were informed (for whatever reason) that stored procedures require a parameter and therefore they built everything with a parameter whether or not it was used.

I have also seen similar development methods used when the developers built a generic utility in code and that utility required all stored procedures to have a parameter - because if it didn't, their nice little generic utility would break.
