I have a table that has 30 columns. I then have a SP that needs 25 columns. So I do:
CREATE PROCEDURE dbo.StudentSelectOne_sp
(
@StudentID int
)
AS
SET NOCOUNT ON;
SELECT col1,col2,col3,.....,col25
FROM tblStudents
WHERE StudentID=@StudentID
GO
Is there a shorter way to create the SP other than typing 25 column names (which can be error prone)?

If you search for "column gitter", you will find a few scripts that will do what you want. Given a tablename a series of column lists is generated (columns, declarations, variables, assignments) in Query Analyzer. Copy and paste the appropriate result in your sp.
The scripts can be changed to allow for more column manipulations.

In Query Analyzer press F8 for the object browser.
Drill down into the database of choice until you find the table you want to work with.
Right click, you'll be able to script a select from the table and you can paste this into your procedure, deleting those columns you don't want to select.
