Simple SEARCH BUILD query = This Group but Not that Group
March 11, 2008, 12:12:35 am
If I want to find people who are in one group (groupID=42) and not in another(groupID=44) can I presume that the following will work
Indiv >> Group >> = 42
Indiv >> Group >> != 44

I am expecting the answer to be yes, at which point I would say .... but it didn't work.
# in 42 is 531
# in 44 is 299
# returned for 42 NOT 44 is 139 and definitely includes people who are on both lists.

Any pointers?

can u get chris to check the generated sql and see what the problem is

i think the issue might be that sql semantics != set semantics for our data model

A person is in a group if there is a group_contact record with a status of Added for that group
A person is NOT in a group if there is no group_contact record OR there is a group_contact record with the status NOT Added for that group

The NOT case is a bit more tricky since it involves an OR clause and i suspect the sql we generate does not account for it
