Hi, ZSQL methods can have two types of string argument, string and required, where required is a non-empty string and a string is (one assumes) a potentially empty string. Although does not say in the ZSQL users guide, it would be nice if strings were also not required to exist as arguments, which to my mind is the logical progression of allowing an empty string. The reason I want to do this is that I am writing sql methods which build queries based on the existence of certain arguments. Obviously I can code the logic to test for empty strings, but it would be neater and simpler to be able to simply have <dtml-if myarg> ... The other reason this would be a neater solution is that it would avoid the need to set up lots of empty arguments in the dtml which calls the sql method. Comments?
