Openbravo开发-开发篇 为字段填加触发器

也在数据库端实现，必须填写正确的前缀。
提供软开关（IF AD_isTriggerEnabled()='N），可以停掉或打开所有的触发器
CREATE OR REPLACE FUNCTION ht_salary_trg()
   RETURNS TRIGGER AS
$BODY$ DECLARE

DECLARE
    v_IsEmployee CHAR(1);

BEGIN

   IF AD_isTriggerEnabled()='N' THEN IF TG_OP = 'DELETE' THEN RETURN OLD; ELSE RETURN NEW; END IF;
   END IF;

   SELECT IsEmployee
     INTO v_IsEmployee
     FROM C_BPartner
    WHERE C_BPartner_ID = NEW.C_BPartner_ID;
  
    IF v_IsEmployee = 'N' THEN
      RAISE EXCEPTION '%', 'Partner is not employee';
    END IF;

    IF TG_OP = 'DELETE' THEN RETURN OLD; ELSE RETURN NEW; END IF;

END;
$BODY$ LANGUAGE plpgsql;

CREATE TRIGGER ht_salary_trg AFTER INSERT OR UPDATE ON ht_salary
     FOR EACH ROW EXECUTE PROCEDURE ht_salary_trg();
需要导出数据库
ant export.database
