Question of the Week - 28/12/2013 - Question 2

Question:- Suppose we have a table named tbl_charactername have only one column say "charactername".
It contains 10 rows. First 5 rows contains "Vivek Johari" and the next 5 rows contains "Abhinav Golwalkar"

tbl_charactername
---------------------
Vivek Johari
Vivek Johari
Vivek Johari
Vivek Johari
Vivek Johari
Abhinav Golwalkar
Abhinav Golwalkar
Abhinav Golwalkar
Abhinav Golwalkar
Abhinav Golwalkar

Now we need a SQL Query which can return the result in the form

Desired Result:-

Vivek Johari
Abhinav Golwalkar
Vivek Johari
Abhinav Golwalkar
Vivek Johari
Abhinav Golwalkar
Vivek Johari
Abhinav Golwalkar
Vivek Johari
Abhinav Golwalkar

Query should work even if the table has 30 rows with first 15 contains "vivek johari" and next 15 contains "Abhinav Golwalkar" or 40 rows with first 20 contains "vivek johari" and next 20 contains "Abhinav Golwalkar" etc. But output should contains "Vivek Johari" and "Abhinav Golwalkar" in alternate rows.

Keep Answering.......:-)
