There are some users who use a SQL Server 2000 database strictly for data export using a DTS package. Data privileges are not an issue, but restricting their ability to view (and potentially copy) custom T-SQL code is a concern.
I'd like to lock them down to prevent them from viewing code (stored procedures, user-defined functions, triggers, etc.) while continuing to allow data access.
How can that restriction be set for a group/role in Enterprise Mgr?
Thanks in advance!

Stored procedures and possibly views and triggers can be created with an encryption option which would protect that code and therefore help hide your code.

Make sure to keep an uncompiled copy in a safe place.

Appreciate your input, Brian.

It sounds as though the options may be limited to (1) encrypting as you described, or (2) the user accomplishing the tasks without Enterprise Mgr as an interface.

Does that sound about right?

Just be aware that in SQL 2000 decrypting encrypted stored procedures was a fairly trivial operation.

There is a TSQL stored procedure:

sp_helptext [ @objname = ] 'name'

which displays the code unless there is an encryption option set.

So your option to deny Enterprise Mgr won't solve the problem.

As Gail said there may be easy ways to avoid the encryption in SQL 2000, and if you are that concerned about people getting the code, a re-design or move to SQL 2005 may be in order.
