I tried to get a max value of a column with type date. The codes are like: Criteria crit = new Criteria(); crit.add(XXXXPeer.String, Object, Criteria.EQUAL); crit.addSelectColumn("MAX(" + XXXXPeer.aDate + ")"); crit.add(XXXXPeer.String, Object, Criteria.EQUAL); List result = XXXXPeer.doSelect(crit);
But it is not working. The exception says: Error: org.apache.torque.TorqueException: Illegal conversion: com.workingdogs.village.DataSetException: Invalid type for Integer Does it mean it is type related? Another question, what is the key difference between Criteria.add and Criteria.and? Thanks in advance.

Ther it is described how to select count(*) from a table.
