Hm, should have checked this link first...
Still I am not yet convinced, or at least a little confused:
Given a table "a" with columns "cola" and "colrestricted".
User "Test" only has access to column "cola", but not to "colrestricted".
Then I execute the following queries:
SELECT * FROM sys.objects WHERE EXISTS(SELECT cola FROM a)
SELECT * FROM sys.objects WHERE EXISTS(SELECT 1 FROM a)
SELECT * FROM sys.objects WHERE EXISTS(SELECT * FROM a)
Now I get an error from both the 2nd and the 3rd query! (Permission denied on colrestricted)
Why is query 2 (SELECT 1... ) giving me an error?
Thought Id ask you first instead of addressing this to Conor directly. There is probably a simple explanation...
Thanks!
