    How to modify SP name in Alter Proc script ?

    Good question 🙂

    I was also thinking upon this. Instructions in the Question should have stated something like this:

    Right-click on the procedure name in the object explorer. Select "script procedure as" and Create to new query window. Change the procedure name to 'rename_by_alter'. Execute the script.

  • Fortunate enough to get this correct. But the question required lot of reading and thinking!

  • Instead of saying modify using alter script, Author could have said drop and recreate with new name. Luckily igot it correct.

    I thought the same thing ,and was looking for error ;

    so I assumed , it's drop and recreate.. that's one way of renaming too ..But, This would require reassigning the permissions on stored procedures afterwards.

    Wondering what I would do next , when I am done with this one :ermm:

  • Now right click on the procedure and select 'modify', get the alter proc script and change the procedure name to 'rename_by_alter'. Execute the script.

    How can we modify the stored procedure name using Alter window...

    It will always throw an error stating:

    Invalid Object Name 😉

  • As happens more often with a Question of the Day: Good idea, but badly executed.

    If you exactly follow the instructions, executing the 'alter proc' script after making the change will result in an error (because you are trying to alter a procedure that doesn't exist). And then the statements 3 and 4 will of course also return an error.

    Since that option was not available, I had to second-guess what happened when the author submitted the question. The most logical explanation was that he already had a stored procedure 'rename_by_alter' when he started creting this question, so instead of altering the proc he thought he changed, he altered that other already existing proc. I then picked my answers based on that assumption, and I got it right.

    Lessons learned:

    1. Using sp_rename to rename a programmability item does not change its definition in sys.sql_modules. That's why Books Online recommends to use DROP / CREATE instead.

    2. You can't use ALTER PROC to rename a procedure.

    3. Submitters of a Question of the Day should always test their questions on an empty database before submitting their question.

  • Nice question, but could have been worked out a little better.

  • I didn't even notice the conusion about the 'rename_by_alter' instructions. I was already aware of the behaviour of sp_rename/sp_helptext, so0 that ruled out the 1st option. 2 and 3 were ruled out because the third answer related to the first procedure, so couldn't possibly be correct for the completely unrelated second procedure. Which only left one answer 🙂

  • Knowing already that using sp_rename does not change its definition, and with there being no error scenario in the answers, I had to take the only possibly logical answer available. Thereby presuming a DROP/CREATE scenario, rather than ALTERing a "procedure that does not exist", was the intention of the author.

    Good question, just badly implemented.

    Thanks.
