Does anyone know if there is another language or set of commands beside SQL for talking with databases?

I’m working on a project and am doing some research thanks

Give it a shot on a test SP. Shoot me an email if you have questions. Cheers.

Got the script. I’m wishing I had some encrypted sp’s on sql 2005 to use it on. It’s in my utility belt now so i’ll have it if i need it in the future. Thanks.

Sent the script, to your email, that creates a SP that decrypts a SP that has been encrypted CREATED or ALTERED “with encryption” in SQL Server 2005. I found it on Google Groups and it seems to only do SP’s. I am going to try to alter it to do Views also. Let me know if you didnt get it.

I didn’t try the script with sql 2005 so it’s probably the factor. What did you do to get it working? If you wouldn’t mind, email it to shawn@tubejumper.com, I’d love to take a look.

Ok, I got it to work. Decrypting that is. I think (but not sure) that the problem I had was I was using a SQL 2005 database. Further Google searches revealed this thread:

For now, this works good for me. My sprocs arent greater then 4K.

Thanks for putting up with me! :-)

Hello Shawn, I see…. I am logging in with “sa” and have full rights. Its a development DB and I am the only developer on this (now) as the other developer has left, and left me with encrypted sprocs.

I will restore and then try to run this script once, halting it where it has decrypted the sproc and hopefully I can see what its about to replace (on that delete and create step).

It might be do to the rights given to the id your connecting to sql with. If it doesn’t have the right to create sp’s then these tools will not work.

There is no function in sql that will unencrypt the sp’s. What the tools do is decrypt them in memory and then recreate them again by deleting and running the create sp comand with the contents unencrypted.

Hope that makes sense and not circular.

Didnt work. :-( The script simply deleted all of the stored procedures, those the messages seemed to indicate that it ran OK.

spACCOUNT_Delete – Decrypted
spACCOUNT_Update – Decrypted
spACCOUNT_Insert – Decrypted
spACCOUNT_Copy – Decrypted

and so on.. 150+ SP’s deleted.

I will have to restore. Why would it delete them. There were no signs of them anywhere, just the sp_decrypt_sp that was being called to decrypt…

Oh well. Almost every solution I’ve tried simply deletes the SP and doesnt decrypt them.

OK, cool. I will give this a try. Thanks so much!
