Answer 1

Welcome bro, you can not do it like that, when you select two columns then it will back in your query , on (where) command or sql you can search by any one of the columns , but you can select the columns that you want to see in the result .

this is example for sql query :

SELECT real_easte.category, real_easte.yard FROM `real_easte` WHERE number_of_floor = 2

where is select this two columns ( real_easte.category, real_easte.yard ) and search by (number_of_floor)

i hope that clear idea for you
