Well.. will try ONE more time then.


1 - The customer can add any value into users.code column
2 - The customer can chose between *add or no**t* 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

In addition to what John and David said, from your original post:

"DROP FUNCTION IF EXISTS client_code_increment_count();
CREATE OR REPLACE FUNCTION "public"."client_code_increment_count" () RETURNS TABLE("code" INT) AS
$BODY$
SELECT MAX(CAST(users.code AS INT)) FROM users WHERE users.code ~ '^\d+$' AND company_id = 2
$BODY$
LANGUAGE sql;
SELECT * FROM "client_code_increment_count"();"

If I am following, this duplicates the information in companies.client_code_increment, in that they both return the last non-user code. Of course this assumes, as David mentioned, that the client is not using a numeric code system. Then you are left trying to figure whether a number is 'your' number or 'their' number?
