Re: SQL User Defined Function Not Found

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

This is the classic issue with functions & stored procedures - you 
defined the parameters as character but are passing literals. Literals 
are cast to varying char type by SQL, so the prototype does not match.

You can do something like char('L') or cast('L' as char(1)) - check the 
syntax there, I don't use cast very much - usually use the char function 
itself.

I also don't know if there is any benefit to the CONST - or even if 
those will work - i seem to remember something to the contrary.

You could define all the parameters as varying, too.
