Vous pouvez le faire avec AND et OR tant que vous utilisez suffisamment de parenthèses.
Aussi, je suppose que activities.OrderBy peut être nul. Si ce n'est pas le cas, vous pouvez supprimer la vérification nulle :
SELECT activities.*,
activitytypes.orderby
FROM activities
LEFT OUTER JOIN activitytypes
ON activities.typeid = activitytypes.typeid
WHERE activities.userid = 86
AND activities.typeid NOT IN ( 5, 10, 11, 12, 19 )
AND ( ( activities.orderby = 1
AND activities.starttime >= '2013-08-26 04:00:00'
AND activities.endtime <= '2013-08-27 04:00:00' )
OR ( ( activities.orderby IS NULL
OR activities.orderby != 1 )
AND activities.activitydate = '2013-08-26' ) )
ORDER BY activitytypes.orderby,
activities.starttime
Sinon, si vous souhaitez toujours utiliser CASE , il vous suffit de fermer votre CASE instruction utilisant END , comme ceci :
SELECT activities.*,
activitytypes.orderby
FROM activities
LEFT OUTER JOIN activitytypes
ON activities.typeid = activitytypes.typeid
WHERE activities.userid = 86
AND activities.typeid NOT IN ( 5, 10, 11, 12, 19 )
AND (
CASE
WHEN activities.orderby = 1 THEN
activities.starttime >= '2013-08-26 04:00:00' AND activities.endtime <= '2013-08-27 04:00:00'
ELSE
activities.activitydate = '2013-08-26'
END
)
ORDER BY activitytypes.orderby,
activities.starttime
