I'm having difficulty with ordering on a calculated field, the order
is just not doing what I expect. I'll post the query here, it is a
distance calculation based on lat and lng so it quite complex....
SELECT * , (
ACOS( LEAST( 1, COS( 0.898348891269513 ) * COS( -
0.00293599286770486 ) * COS( RADIANS( stations.lat ) ) * COS( RADIANS
( stations.lng ) ) + COS( 0.898348891269513 ) * SIN( -
0.00293599286770486 ) * COS( RADIANS( stations.lat ) ) * SIN( RADIANS
( stations.lng ) ) + SIN( 0.898348891269513 ) * SIN( RADIANS
( stations.lat ) ) ) ) * 3963.19
) AS distance
ORDER BY `distance` ASC
LIMIT 0 , 30
So basically distance is calculated then I just want to order on
this, however this is what I get out....
So I'm confused, what strange kind of ordering is that?
Any help much appreciated,
