Note down two things for your success as a tester in life................................First, when you are doing testing, you have a problem, you need not to why application is behaving like this.This is the case only when you are doing compatibily testing.,...................................second , whenever ask any question , define it completely, how you phase the problem , what you think about the problem. ok.To isolate the bug, fill the bug report with steps you followed, when problem occur.attach the screen shot as well, for better explanation.

Here we have to verify the two things,
Is it the application error or database error. To verify this Disconnect the datbase  and follow the stpes to reproduce this error. In this scenario if error is not coming then problem with Backend (database) and if error is still coming then there is problem with frontend (Application)

In my attempt to isolate the problem, I would:

1) consider the nature of the error that is generated.  This should tell me a great deal about the source of the error.

2) consider the nature of testing I had been conducting when the error was generated.  For example, if I had been performing boundary value analysis on a text box, this will lead me down a different path than if I had been testing the constraints on a database or the edge capacity to use resources.

3) consider anything that interacts with the application which may be causing the error.  this could be another program on the local computer, a remote server, a web service, a printer, or database.  If there are multiple dependencies, I would remove one at a time to determine whether any of them (and possibly a combination of them) are causing the error. 

4) retest with the same data to determine whether or not the issue is reproducible.

5) enter radically different data to determine whether this breaks the functionality as well.

6) enter similar data.  For example, if the original number was 'n', I would enter n+1 and n-1 and observe results.
