How To Hide An Alias Column In Mysql Edited
I know this is a replica of some question asked already, but i need some suggestion. I know basics of MySQL, i have a query to calculate distance between latitude and longitude and
Solution 1:
You would want to use a subquery:
select wp_id
from (select cl.wp_id,( 3959*acos( cos( radians(12.91841) ) *cos( radians( y(gproperty) ) ) *cos( radians( x(gproperty)) - radians(77.58631) ) +sin( radians(12.91841) ) *sin( radians(y(gproperty) ) ) ) ) AS distance
from db1.geofeature gf join
db2.c_loc cl
on gf.o_type =256and cl.c_info_id =146and gf.o_id = cl.wp_id
) t
where distance <10orderby distance
limit 10;
Notice that I also fixed the join syntax to use explicit joins.
