Just a question which came into my mind by reading at this email. It has been said that JSPs allow separation of roles between the web and the business developers so that, ideally, the former should work independently by the latter. Then, because prior to Struts-el :) some java code was mungled within the JSP code, then Struts-el came out. I am wondering whether an <sql:update> element as the one below, would actually separate the front-end developer by the business developer. At the end, hasn't Struts been invented to exhibit an handful MVC framework for web applications?

I have a form <form> .... <input type="text" name="time" /> <input type="submit" name="submit" /> </form> and then a nice sql update to catch the form <sql:update> INSERT INTO myTable VALUES ( ? ) <sql:param value="${param.time}" /> </sql:update> The problem comes when the form parameter is empty. Since the actual database field is a mySQL TIME field, there is a very big difference between an empty string and a null. Empty strings will be converted into '00:00:00' in the database but nulls will just stay null (nulls are allowed and no defaults are specified). The sql:param tag will never return a null if there is a "time" key in the params. Since the form always posts the parameter, I'll always have '&time=&somethingelse=' in my request. <sql:param> sees this as an empty string "", which becomes '00:00:00' in my database. This however, works: <sql:param><c:out value="${param.time}" /></sql:param> I am assuming that this is an intentional thing, but I'm not sure and I'd like to know why. Anyone?
