Обсуждение: INSERT OR UPDATE WITHOUT SELECT

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:
