Hi Frank,

This is much too complex a design that easily leads to problems.
Generally, you should not make the fields do dual/triple use. I would
suggest you have two numeric fields, a ChurchID and a MemberID and make the
two of them your primary key. Keeping the ChurchID separate allows you to
create and enforce referential integrity between your Churches table (you do
have a Churches table don't you?) and other related tables such as Members.
Additionally, if you need the year of joining, make that a separate field
also. Create a combo box on your form from which the user picks the
appropriate church. This will eliminate the need to do any validation, or
other coding on the ChurchID. Populate your MemberID by using a "select
Max(MemberID) from Members where ChurchID = " & cbChurchID recordset in the
before insert event. For the addresses I presume that you are allowing for
multiple addresses per member. In which case use three columns, ChurchID,
MemberID and AddressID, which will be your primary key. You can then set the
AddressID in the address (sub)form's before insert event using the same type
of process as setting the MemberID. Now, if the actual combined
church/member number is needed, you can just blend them together in the
appropriate queries and/or reports.

There are other ways to do this, including making some of the ID fields
autonumber fields so you do not have to do any ID calculations.

Hope that helps,

Clifford Bass

Thanks Cliff for your response. Let me tell it you the back ground, that I
have finished desingning a database for our local church using memberID and
AddressID AutonumberPrimaryKey. Now I want to develop it to be able to used
by all churches of our denomination. The same software will be used by our
regional office to combine all church membership data. However the primary
key of both memberID and AddressID could duplicate and wil resut in a
confilct when combined in a regional office. So the idea is how to make it
always unique. Also to make it more practical when we are using a combo to
select the address of a member we prefer 1 field PK, because in this database
we can see the members per address to facilitate a pastor to visit that
household.

So since I want to keep these MemberID dan Address ID always Unique I make
the combination of these 2 PK into 1 PK. All the church ID will be alwasy
requested from me as a software developer.

So please help me how can we make these 2 PK into 1 PK.

Thanks in advance,

Frank

Hi Frank,

I understand your reasoning for wanting to make the church ID part of
the member ID and address ID, but I again strongly encourage you not to go
that route. Making your primary keys compound keys (keys that are made up of
more than one column) will solve the need for uniqueness. And, the issue of
a combo box is not really an issue. You can make the combo box contents
dependent on a church ID field on your form. Also, it is a mistake to say
that you have finished designing the database. Limiting yourself in that way
easily leads to poorly designed systems.

Regarding the need to show other people at the same address I would
change my recommendation to this: The addresses table will use a ChurchID
and an AddressID but not a MemberID. Create a fourth table that links
between the three tables maybe a MemberAddresses table that contains a
ChurchID, a MemberID and an AddressID. This will let you navigate back and
forth between a member, his addresses and anyone else living at his addresses
very easily. It also allows for multiple addresses per member such as a
winter address and a summer address. This of course presumes that no one is
a member of more than one church and that the addresses are specific to each
church. If you want to accomodate for multi-church membership situation and
avoid having duplicate data for the same people and addresses, it will
require some significant rethinking of member and address ID numbers; how to
make sure they are unique across all of the denomination, not just for each
church. Then you would eliminate the church ID from the members and
addresses tables. The MembersAddresses table would provide for the
connections between all of the tables.

However, if you still want to use the IDs as a single field where the
first four digits are the church ID and the second four are the member or
address ID I would suggest the following: Create an unbound combo box that
lists the available churches and defaults to the default church. Make your
member (or address) ID a locked field that is not modifiable by the user.
Then use one of the following select strings to get the new member number in
the before insert event.

This one assumes that you are storing the IDs as long integers:

strSQL = _
"SELECT " & Nz(cbChurchID, 9999) * 10000 & " + " & _
"Nz(Max([ChurchMemberID] Mod 10000), 0) + 1 AS NewMemberID " & _
"FROM tblMembers " & _
"WHERE Int([ChurchMemberID] / 10000) = " & Nz(cbChurchID, 9999)

Or, if you are using eight-character IDs use this:

strSQL = _
"SELECT " & Nz(cbChurchIDText, "9999") & " & " & _
"Format$(Nz(Max(Right$([ChurchMemberIDText], 4)), 0) + 1,
""0000"") AS " & _
"NewMemberIDText " & _
"FROM tblMembers " & _
"WHERE Left$([ChurchMemberIDText], 4) = """ & Nz(cbChurchIDText,
"9999") & """"

I think that I got those statements right. You will need to adjust the
combo box, table and field names as needed. It will always return the next
new member (or address) ID, including when there are not any for the selected
church or if there is no selected church. The only problem will be when a
church exceeds 9,999 members and/or addresses.

Hope that helps,

Clifford Bass
