I have a FB2.5 table with a generator and trigger to increment a PK. In IBExpert, the table increments correctly when I add a record. However, when I try to do it using code in Delphi XE with IBObjects (TIBOTable). I get an error that says the primary key field must have a value.

This is the code I use:

tableGIS_Config.Open;
tableGIS_Config.Insert;
tableGIS_ConfigUSER.Value := User;
tableGIS_Config.Post;
