在数据库中触发插入

Question

CREATE OR REPLACE TRIGGER no8 BEFORE INSERT ON pegawai FOR EACH ROW 
   BEGIN 
     IF :NEW."gaji" BETWEEN '1000000' AND '3000000' THEN 
         insert into pegawai
              ("no_ktp", "nama", "jenis_kel", "alamat", 
              "tgl_lahir", "gaji", "no_dep")  
         values (:new."no_ktp", :new."nama", :new."jenis_kel", :new."alamat",
                  :new."tgl_lahir", :new."gaji", :new."no_dep"); 
     END IF; 
   END;

我尝试插入此查询，

插入 pegawai 值 ('20104490002','NELA','2','SIDOARJO','14-AUG-1975','900000','5')

但它给了我这个错误：

ORA-04098: trigger 'SYSTEM.VALIDASI' is invalid and failed
re-validation

请帮帮我..

您不能对作为触发器对象的表在触发器上使用插入语句。主要不是BEFORE。它可能会陷入无限循环。

如果您尝试更改要在表格中插入的值，您只需更改 :new.FIELD_NAME 上的字段值

举个例子：

IF :NEW."gaji" BETWEEN '1000000' AND '3000000' THEN
    --say that you need to change the value of :new."nama" just do:
    :new."nama":= 'new Value';
end if;
