Unique Constraint Error on variable.add()

Hi Guys,

i search already in all related documents (Docu, Forum, web) but can't find the correct way how to check if a unique entry in database already existed.

So, how can i avoid the unique constraint error when the value is already in the database and check this before in a multithreading environment?

I hope my question is clear and you can point me in the right direction - thanks!

Re: Unique Constraint Error on variable.add()

Why not call first TSQLRest.Retrieve() ?
