Is there some trick to getting the QueryTask to work on an ORACLE date field in the Silverlight API? Here's what I have tried so far in the Where string:
MyFieldName = TO_DATE('2010-04-19 00:00:00','YYYY-MM-DD HH24:MI:SS')
MyFieldName = TO_DATE('2010-04-19','YYYY-MM-DD')
MyFieldName = TO_DATE('12/19/2010','MM,DD,YYYY')
The error message I get from the API is "Unable to complete Query operation"
