backup goes on a user's request
1. the code fetches up data from about 39 tables where new_backup = 0
which meanz the data iz new and has never been backed up before
2. after the data s fetched the code updates all new_backup = 1
through out the 39 tables
3. a file is saved on the local disk
(this waz the clients requirement they want the data to be backedup
on local machines as the internet connections are horrid in most
parts of the country where they ll be running the applicaiton n its
to be restored by the administrator in the headoffice when he gets
the file stored on a disk or sumthin)
4. the administrator then can retore the backup on the server
he ll have to run the script file brought in (the backup file)
creating a new dtabase on his server
4.i there are 9 prime key tables proj_unit(pu), union_council(uc),
supervizor(sup), village(vill), community-health-worker(chw),
family(fmly), mother(mo), child(chld),
other-family-memberz(othr-fmly)
4.i.a : fetch pu's from backup db
compare against pu in server db
if match found
get server db pu_ids
replace backup-db pu_idz by servers
else
get max(pu_id) from server db
inzert pu from backup db into server with its id==max(pu_id) from
server db
4.ii: loop 4.i for all 9 tables
5. now all the prime key tables have unique values
so i can move in to inzert the rest of the data from backup-db to
server db
n this is the problem
all my primary keyz are auto-increments
if i inzert the data as i picked it up from the local machine along
with its primary-keyz i get an error for duplicate entries
i guess the backup that i actually fetch otta be without these
primary keyz but then i need the primery keys of the 9 prime tables
what the fuck m i suppozed to do
im sorry fo soundin freeked out
but this thing is gonna b deployed in about 20 hours from now
:'(
can sum1 plz help
