Hi,
Is there a command to Insert a record If It does not exists and a update if
It exists?
I do not want to do a select before a insert or update.
I mean the postgres should test if a record exist before insert and if It
exist then the postgres must do an update instead an insert.
Thanks,
WMiro.

Not a single command, but a solution:
