Re: Function PostgreSQL 9.2

1 - The customer can add any value into users.code column

2 - The customer can chose between add or not add the value on users.code column

3 - If users.code is null (because the customer's chosen not to add any value in there), a trigger/function has to do the job.

4 - the function/trigger add the next available value, which the default is 1000 and it's stored on companies.client_code_increment

why don't you use a SEQUENCE for this?

    ... DEFAULT nextval('sequencename') ...

initialize the sequence to 1000.

done.

still sounds pretty sketchy.
