Subject [jira] [Created] (CAY-1951) Support ISO-8601 date/time Strings in Expressions
Date Tue, 02 Sep 2014 13:13:21 GMT
Andrus Adamchik created CAY-1951:

             Summary: Support ISO-8601 date/time Strings in Expressions
                 Key: CAY-1951
             Project: Cayenne
          Issue Type: Improvement
            Reporter: Andrus Adamchik
            Assignee: Andrus Adamchik

When creating Expression's from Strings, we only distinguish between numeric and String values.
So passing a date/time/datetime as a String is not possible. I think we can improve that...
If a left-hand side path of a binary expression is a property that is a java.util.Date , java.sql.Date,
java.sql.Time, java.sql.Timestamp, we should be able to parse a right-hand side value to the
corresponding object. 

The biggest caveat is that we can't do this transformation at the parse time. Base expressions
are abstract and have no notion of the path type. So only when expression is evaluated (either
translated to SQL or evaluated in-memory) can we make the assertion above.
