Question

I need to have 3 columns in a table called prize
Fields are: Event_id, Place, Place

I need to find the square root of the prize money divided by 2, round to a whole number and then display this in a column called New_Money with the 3 other columns (Event_id, Place, Money) without actually storing the New_Money data in a table. Oh, I also have to use the power function.

I started testing with:

SELECT ROUND(money*money/2) AS New_Money
FROM prize;

This gave me a column called New_Money with the correct data, but no other columns.
I couldn’t work out how to get the other columns to display in the same string, AND this isn’t using the Pow() function anyway.

I tested:

 SELECT pow(money,money) AS New_Money
 FROM prize;

But gave an error and is still “fetching” 5 minutes later….

Any ideas?

Answer 1

You are using POW in a wrong way. Try this

SELECT  Event_id, Place, Money,pow(money,2)/2 AS New_Money FROM prize;
