Acabei enviando o e-mail errado e faltou informacões...
*Vamos lá novamente:*
Possuo duas tabelas:
*- users*
- code (Coluna)
*- companies*
- client_code_increment (Coluna)
A coluna users.code, recebe um código pelo cliente. Mas ele pode escolher
em não por nenhum dado lá.
Caso o cliente escolhe por não inserir nada na coluna, eu tenho que dar
para ele um número... um value....
O default é 1000
Por que adicionar um valor DEFAULT a users.code não é uma solucão?
>
Porque o cliente pode escolher em por algum outro dado nesta coluna. Então
um valor DEFAULT não é a saída
Qual é o default code?
>
O default é 1000.
O cliente pode por qualquer coisa no users.code, porém se lá estiver NULL,
se o cliente não puser nada, nós irá setar a próxima value... 1001, 1002,
1003 etc
>
> O que é increment_client_code?

É uma coluna onde armazena o último client_code usado:
ALTER TABLE public.companies ADD COLUMN client_code_increment integer;
ALTER TABLE public.companies ALTER COLUMN client_code_increment SET DEFAULT
1000;
*table users:*
> CREATE TABLE

*Table companies:*

> enable_job_share BOOLEAN DEFAULT true,

Como posso fazer isto acontecer? Como posso criar a funcao e o trigger para
tal?
Aqui está o que fiz até agora: (Mas não consigo seguir)
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"();
> CREATE OR REPLACE FUNCTION "public"."auto_generate_client_code_if_empty"
> () RETURNS "trigger"
> VOLATILE
> AS $dbvis$
> BEGIN
> END;
> $dbvis$ LANGUAGE plpgsql;
>
> CREATE TRIGGER "increment_client_code"
> BEFORE INSERT OR UPDATE ON users
> FOR EACH ROW
> EXECUTE PROCEDURE "auto_generate_client_code_if_empty"();
Obrigado. Lucas
