Thanks, but ... 1) I want to hide this hint from users , which will use this function, it means I want keep hint in the body of function. 2) interesting point is that other hints, like NOLOCK, can be embedded in user-defined function without any problem. Thanks again ... |

You can use several table hints in same query (for each table, join, ect.) but only one OPTION clause. For example you can't create a view with OPTION clause. But you can create a view with several table hints. So a think it's the feature. OPTION hint(s) should be used throughout the entire query . So it's impossible that something in FROM Clause (inline UDF, view) already contains OPTION hint(s). ... |
