- Please change the title to something more comprehensive and do not continue to post simpy error messages.
- Give a couple of details what you are actually trying to achieve.
- Possibly a short section of code may help to give others an understanding of your goal.

In addition to @koahnig said, looks like you are trying to open the DB connection from two places in your code. Hence getting into this issue.

@veera "How to fix the errors please explain me......."
please note that people in this forum are giving you the solution based on the problem statement you explain. Based on your error message I suggested possible condition. Without you sharing the code no body can help you to fix the problem. Your response to my suggestion looked harsh to me. Be polite & people are helping here based on their interest.

QtRPT
Almost any answer within this forum may be crytal ball reading to your problems. As also @dheerendra iterated and others including myself have asked for some code samples showing were your problem is. QtRPT is not Qt and simply using Qt libraries as many other software and tools. You might be lucky and there is a user of QtRPT in this forum, but your chances are much better to address your questions in the QtRPT forum.

yes it is a reporting design tool.....
