[Zope] ZSQL arguments

[Stephen Harrison]

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?

Cheers,
Stephen
