php - Why do i get this result? -

- 

select *  afspraken user_id =  '2' , datum >  '2012-06-05' or ( user_id =  '2' , datum =  '2012-06-05' , begintijd >=  '22:47' ) order datum desc , begintijd asc

this above query.. , while should 0 result still 1 is:

id  user_id     datum      begintijd    opmerking 114 2         2012-06-05    9:30        deze afspraak online gemaakt.

now if have correctly, query has 2 options give results.. is: user_id must same , date has higher 2012-06-05.. since same date won't give result..

now second option when user_id same, date same , when beginningtime same or higher.. time in query shown 22:47.. time in database 9:30 morning.. how 9:30 morning higher or equal 22:47??

    id  int(10)                                  user_id int(10)      datum   date         begintijd   varchar(5)     opmerking   varchar(8000)     reminder    int(10)

the idea cast time columns , values time:

select cast('20:05' time) > cast('9:06' time) #returns 1 (compares times - want)  select '20:05' > '9:06' #returns 0 (compares strings - not want)

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...
