• How to save a Stored Procedure ?

  - by Richard77

  Hello, I've been playing today with stored procedures. I'm stoned that I picked the basic of it up so easily. (I'll also try triggers very soon). Now, I'd like to know how to save my SPROC under the stored procedure folder (Programmability - Stored Procedure) so that I can access it by name (eventually from my C# application).

• I need to programmatically remove a batch of unique constraints that I don't know the names of.

  - by Bill

  I maintain a product that is installed at multiple locations which as been haphazardly upgraded. Unique constraints were added to a number of tables, but I have no idea what the names are at any particular instance. What I do know is the table/columnname pair that has the unique constraints and I would like to write a script to delete any unique constraint on these column/table combinations. This is MSSQL 2000 and later. Something that works on 2000/2005/2008 would be best!
