I have a query for result show Now, I need sum m1, m2
Query is:
select metraj, fee, tedad, fee_tedad,
metraj * fee AS m1,
tedad * fee_tedad AS m2
from content
where id = 54
Do like this
select metraj, fee, tedad, fee_tedad,
metraj * fee AS m1,
tedad * fee_tedad AS m2,
metraj * fee+tedad * fee_tedad as sum
from content
where id = 54
select metraj, fee, tedad, fee_tedad, metraj * fee AS m1, tedad * fee_tedad AS m2, mtraj * fee + tedad * fee_tedad as m1_plus_m2 from content where id = 54
The following should work :
select metraj, fee, tedad, fee_tedad, (metraj * fee) + (tedad * fee_tedad) AS someVariable, from content where id = 54
If you need both m1 and m2 also then use the following :
select metraj, fee, tedad, fee_tedad, metraj * fee AS m1, tedad *fee_tedad AS m2, (metraj * fee) + (tedad * fee_tedad) AS someVariable from content where id = 54
