Обсуждение: problem with serial data type and access
I know it's not fully IT with the list, but maybe somebody can help me. I'm dealing with this scenario: access 97 is connected through odbc to a postgresql server. All tables are saved in postgresql and access is used only to generated the program interface. Everything works fines, but I'm having problems with the serial data type. I know a serial is an integer having as default the next value of a sequence. Since it is an integer, access does not recognize it as an autoincrement value, and it asks for is value. Did anyone of you already have this problem? Thanks... -- Non c'e' piu' forza nella normalita', c'e' solo monotonia.

Can you feed it a value of DEFAULT???

I'd like to, but I don't think I could do it. The fact is that the serial data type is in pratice an integer, and when I also try to connect with pgadminIII I see an integer data type and not a serial. I think that since it sees an integer, it does not understand that it is a serial, and access does not recognize it as autoincrement. I'm stuck at this point... -- Non c'e' piu' forza nella normalita', c'e' solo monotonia.

Did you mark this field as the primary key when you linked the table? -- Adrian Klaver aklaver@comcast.net

Back when I was using V95, I remember having this problem and finding
a simple way to get around it. The only problem is that I can't
remember what it was. MS-Access 2003 doesn't seem to suffer from this
problem.
One brute-force method to get around it is to create a function that
uses an ADO connection to call the PostgreSQL back-end for
nextval('sequence_name'). Next using the Before_insert() event in
access, you could manually set the new id for your primary key and
complete the record insertion.
