Why doesn't MIN() work in SQL query?

Question

MySQL

I make a request:

SELECT MIN(PRICE) `table` where ARTICLE='123' AND BRAND='321';

Gives out:
23.00
but if you remove MIN then it gives out

23.00
5.00

Why doesn't it output "5" but outputs 23?

Answer 1

Problem solved - column was VARCHAR. Converted to DOUBLE - everything is ok.

Answer 2

So the record with the result "5.00" does not match the conditions "where ARTICLE='123' AND BRAND='321'"
