I'm stuck:
The tables:
grouptable (groupID, groupname)
usertable (userID, otheruserinformation)
groupusertable (groupID, userID)
Given the userID, how do I get a list of groups that the user is not in?
This will return all the groups that the user is in:
SELECT DISTINCT grouptable.groupID, grouptable.groupname
FROM grouptable LEFT OUTER JOIN groupusertable
ON (grouptable.groupID = groupusertable.groupID) and
(groupusertable.userID = #userID#)
This will return all groups the user is not in, but some other user is:
SELECT DISTINCT grouptable.groupID, grouptable.groupname
FROM grouptable LEFT OUTER JOIN groupusertable
ON (grouptable.groupID = groupusertable.groupID) and
not (groupusertable.userID = #userID#)
Any help, would be appreciated. Thanks
