send a empty string.

>>From you description my assumption is you are not getting this error all the time but are getting disconnected. I have a connection object that I use to handle this situation. When I get an error like this I first test the existing connection to see if it is valid. If it is not valid then I will connect again to the database and try the query again. If the connection is valid then I assume that there is a problem with the query and report the error.
