SQL Stored Procedure Question: How can I combine two stored procedures into one

I have two stored procedures running on Microsoft SQL Server 2000 and 2005. Both of them work fine and I am able to call them from my application.

I would like to combine the two SP into one. My app calls SP1 which returns a recordset. I eveluate the data in the recordset and then, if necessary, call SP2.

I am trying to figure out how to evaluate the output from the query in SP1 and if needed execute the query in SP2...but all from within one SP.

Here are the stored procedures:

SP!:

CREATE PROCEDURE [dbo].[CheckEditVersionStamp]

@strTableName nvarchar(255),
@strIDField nvarchar(255),
@strIDValue nvarchar(255)

AS


DECLARE @SQLStatement varchar(255)

SELECT @SQLStatement = 'SELECT EditVersionStamp, EditVersionTime' +
                                             ' FROM ' + @strTableName +
                                             ' WHERE ' + @strIDField + ' = "' + @strIDValue + '"'

EXEC(@SQLStatement)
GO

**********************************************************
SP2:

CREATE PROCEDURE [dbo].[SaveEditVersionStamp]

@strTableName nvarchar(255),
@UserID nvarchar(255),
@strUserIDField nvarchar(255),
@strUserIDValue nvarchar(255)


AS


DECLARE @Time nvarchar(255)

set @Time = CONVERT(nvarchar, GetDate())

DECLARE @SQLStatement varchar(255)


SELECT @SQLStatement = 'UPDATE ' + @strTableName +
                                             ' SET EditVersionStamp = "' + @UserID + '", EditVersionTime = "' + @Time + '"' +
                                             '  WHERE ' + @strUserIDField + ' = ' + '"' + @strUserIDValue + '"'

EXEC(@SQLStatement)
GO

Thanks.
