What about using a server-side function for doing your insert? This function can simply return the id of the inserted line, and on  the client-side, you open it? This is a very useful method for doing inserts. It allows you to do all kinds of initializations and sanity checks server-side.

Objet : [ODBC] Bound column and serial datatype question


I have a table like this:

  ID serial NOT NULL,
  CustomerNr serial NOT NULL,
  Name CHAR(100),

Using bound columns in a form to show the customer data I don´t like to let the user updating the CustomerNr field. This is because, a normal data field is not autogenerated, but these 'serial' data fields.

But I like to show the CustomerNr field in the form. Therefore, I simply made the field readonly in the form. But if I insert a new row, the fields data (defaults to 0) would be used as the new value in the table.

How to avoid this ?
