I am migrating reports from PRD 6.1 to PRD 8.0,for me singlevaluequery expression is not working in PRD 8.0, is it a bug or do i have to do any extra configuration?
If anybody has faced similar problem then your comments are appreciated.
I found the solution. It was due to the jar file version of mysql. Old version of mysql jdbc connector jar was not supporting advance function so i upgraded to latest version and now it is working fine.
