Question

This is a doubt on mysql select query
let me axplain my doubt with a simple example
consider this is my query
SELECT dbCountry from tableCountry

tableCountry has fields dbCuntryId, dbCountry and dbState
I have the result as

dbCountry 
india 
america 
england
kenya 
pakisthan

I need the result as

1  india 
2  america 
3  england
4  kenya 
5  pakisthan

the numbers 12345 must be generated with the increase in data and it is not an autoincrement id.
How can i get it
is it something like loop

Answer 1

You can try this:

SELECT dbCountry,
(SELECT COUNT(*) FROM tableCountry t2 WHERE t2.dbCountry <= t1.dbCountry) 
AS RowNum
FROM tableCountry t1
ORDER BY dbCountry
