I feel your frustration on my previous question, I apologize for that. English is my second language and perhaps I didn't describe the question clearly in my post. What I am curiously to find out is why after I added the option "WITH ENCRYPTION" to the fast working script (1 second ) will cause it halted (keep querying for hours). I was trying to point out where the option is added by the sample only, not to seek for help to rectify the script.
Together, we can make wonders!
