    hello community

    Can anybody kindly explain to me this statement:

    "In Access, user cannot use an AutoNumber data field to enforce referential
    integrity between tables"

    however

    when I created two tables, and both tables I allow Access created the
    Primary keys for me.

    Thereafter, I use the 1st column, which is the Autonumber, I created a Link
    between the two tables and I also able to Enforce Integrity ?

    why is that so that I can use AutoNumber to enforce integrity ?

    I am using Access 2003

    thanks community

    I guess this must be understood as:
    You cannot use an Autonumber *at both sides* of the relation.

    You definitively *can* use an autonumer (and a long integer at the other side) to enable RI.

Since you're here... we have a small favor to ask...

More people are visiting & reading SPN than ever but far fewer are paying to sustain it. Advertising revenues across the online media have fallen fast. So you can see why we need to ask for your help. Donating to SPN's is vote for free speech, for diversity of opinions, for the right of the people to stand up to religious bigotry. Without any affiliation to any organization, this constant struggle takes a lot of hard work to sustain as we entirely depend on the contributions of our esteemed writers/readers. We do it because we believe our perspective matters – because it might well be your perspective, too... Fund our efforts and together we can keep the world informed about the real Sikh Sikhi Sikhism. If everyone who writes or reads our content, who likes it, helps us to pay for it, our future would be much more secure. Every Contribution Matters, Contribute Generously!
