Hello, I'm working on an access 2000 db with classic asp pages (Jet.OLEDB.4.0), I'm trying to insert two times the same element into a table. the problem is that the db doesn't allow me to do this. How I can know if there are primary key or unique properties on one or more colums on a table?

p.s. I haven't MS Access on my pc.

Whats the error msg?

Thanks for Your answer, but now i decided to use another table to insert some kind of elements...

so If you know a web site or any kind of documentation where I can find the meaning of oledb - ado error codes, It would be very helpful for me.

When an error has occurred, the best way is to copy that err msg and paste in google.

You definitely find a solution for it.
