how can I use like operator with query task in silverlight
can any one help
Some time ago I asked a similar question and I am guessing the same answer applies to you.
Can 10.2 answer Oracle where clause?
Statements with LIKE operator are not standardized queries and they are disabled in 10.2+ by default.
ArcGIS Help (10.2, 10.2.1, and 10.2.2)
Hope this explains the issues you are having.
