------------------------------------
Summary: Support ISO-8601 date/time Strings in Expressions
Key: CAY-1951
URL: https://issues.apache.org/jira/browse/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.
