records are available in my database table joining.
Searching and Deliting queries are working but only UPDATE is not working.

I think records not available in your Joining Table. check it from your database.

The UPDATE command will not generate errors if it cannot find any rows to update.

Get the concatenated string from your Debug windows and run it in the database directly. You database will tell you how many rows (if any) were updated. Your JOINS or WHERE clause might be the problem.
