Try this by removing the e
from ORDER BY clause since you are using the UNION statement:
ORDER BY id
instead of
ORDER BY e.id
题
I have a query like this -
SELECT e.id FROM event e WHERE e.startdatetime<NOW() AND e.isEventDeleted=FALSE AND e.isNeighborlyInvited=TRUE AND e.organized_by!=49 AND e.event_address IN (SELECT id FROM address a WHERE latitude!='' AND longitude!='' AND IFNULL(( 3959 * ACOS( COS( RADIANS(22.6979425) ) * COS( RADIANS( latitude ) ) * COS( RADIANS( longitude ) - RADIANS(75.8597305) ) + SIN( RADIANS(22.6979425) ) * SIN( RADIANS( latitude ) ))),0)<100) AND e.id NOT IN (SELECT eventid FROM event_interest WHERE approvalStatus!='InterestExpressed' AND interested_user=49) AND e.id NOT IN (SELECT eventid FROM event_invite WHERE invited_user=49 )
UNION
SELECT e.id FROM event e WHERE e.isEventDeleted=FALSE AND e.isNeighborlyInvited=TRUE AND e.organized_by!=49 AND EXISTS (SELECT id FROM address a WHERE latitude!='' AND longitude!='' AND e.event_address=id AND IFNULL(( 3959 * ACOS( COS( RADIANS(22.6979425) ) * COS( RADIANS( latitude ) ) * COS( RADIANS( longitude ) - RADIANS(75.8597305) ) + SIN( RADIANS(22.6979425) ) * SIN( RADIANS( latitude ) ))),0)<100) AND NOT EXISTS (SELECT eventid FROM event_interest WHERE e.id =eventid AND approvalStatus!='InterestExpressed' AND interested_user=49) AND NOT EXISTS (SELECT eventid FROM event_invite WHERE eventid=e.id AND invited_user=49 )
ORDER BY e.id,((SELECT AVG(avgr.abc) AS VALUE FROM ( SELECT YEAR(NOW())-YEAR(dob) AS abc FROM user_detail WHERE userid=(SELECT interested_user FROM event_interest WHERE eventid=477 AND approvalStatus='Approve') UNION SELECT YEAR(NOW())-YEAR(dob) AS abc FROM user_detail WHERE userid=(SELECT invited_user FROM event_invite WHERE eventid=477 AND acceptance='Accept')) AS avgr)+(SELECT IFNULL(( 3959 * ACOS( COS( RADIANS(22.6979425) ) * COS( RADIANS( latitude ) ) * COS( RADIANS( longitude ) - RADIANS(75.8597305) ) + SIN( RADIANS(22.6979425) ) * SIN( RADIANS( latitude ) ))),0) FROM address a WHERE latitude!='' AND longitude!='' AND e.event_address=id));
This one is giving me error 1054 unknown column e.id in order clause.
I was checking on google every where its naming mistake, but i am not getting how it is naming mistake please let me know if i am doing any thing wrong.

其他提示
Your original question has been answered. e.id is no more available after UNION. Only id is.
However there is some things I would like to add:
.
select a, b, c
from
(
select a, b, c, d
... -- complete query here
)
order by d;
