AutoNumber on PK
Hello, quick question for you all
Is their any way to use referiential interigty with autonumber fields? I can't use Autonumber with assoative entities, since Access does not allow two AutoNumber fields. I can't create a relationship with ref. integrity unless both fields are AutoNumber ....seems like a catch .22 here! Thanks, Eric

Normally you use an AutoNumber on one side of the relationship and a LongInteger on the other. There is no requirement that both be an AutoNumber (especially since that would almost never work). -- I don't check the Email account attached to this message. Send instead to...

Ah, I was just using "Number"--and Access said it has to be "the same type"
I'm used to the MySQL world, where you just add AUTO INCREMENT to any integer data types (smallint, int, etc) Thanks! (knew it was something simple!) "Rick Brandt" wrote in message . ..
