I’ve got a SQL Function which has 3 parameters. The 3rd parameter has a default value of NULL. However, I cannot just write:

dbo.myFunction(Param1, Param2)

I get the error:

An insufficient number of arguments were supplied for the procedure or function dbo.myFunction.

Therefore I’ve got to write:

dbo.myFunction(Param1, Param2, NULL)
dbo.myFunction(Param1, Param2, default)

Is there a way I can just write dbo.myFunction(Param1, Param2)? I think this is a lot cleaner (and saves me having to modify an existing function which I’ve added a new param to!)

    They are default parameters as opposed to optional parameters & must always be passed in the call with a value or default.

    If you wanted to you could make your existing dbo.myFunction(Param1, Param2) call dbo.myFunctionEx(Param1, Param2, default)
