Solution 2

I want to add an extend to this question.
Let's say there is a table which will map the column names with actual names eg. in this case.

250 | emp1 |
251 | emp2 |
251 | Johny |
252 | Harry | and so on.

And the column names should be (emp1,emp2,John,...) and not (250,251,252,....).

Is there an elegant solution for this?
