Hi, all. I have a ZSQL insert function that requires an optional parameter. The variables are coming from an HTML form, and one of the variables is a checkbox. Apparently, if the checkbox is unchecked, the variable doesn't appear. As a small example, let's say there were two strings and a checkbox, labelled str1, str2 and cb. I need this: insert into mytable(col1, col2, col3) values (str1, str2, cb) as well as insert into mytable(col1, col2) values (str1, str2) if cb is None. I can't find any examples of optional insert variables, just optional join parameters. Also - is there a comprehensive ZSQL document anywhere?
