Visual editor Where clause

Hello,
There he is once more.
On the Visual editor page, I want to limit one option.

I do this by using the Login as determinator.

More closely

And in code

Now this data comes from a SQL View, might that cause an issue?
The Tables in the view are Soort_product and Login.
Thanks for the help once more <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=8948&image=3&table=forumtopics' class='bbc_emoticon' alt=':rolleyes:' />
