Oracle触发器更新同一张表
我有一个触发器,我试图用它来更新它监听的同一个表.
I have a trigger which I'm trying to use to update the same table it listens to.
但是,在提交创建或更新时,我收到以下错误:
However, upon submitting a create or update, I get the following errors:
ORA-04091: table [username].ADDRESSES is mutating, trigger/function may not see it ORA-06512: at "[username].ADDRESSES_T1", line 9 ORA-04088: error during execution of trigger '[username].ADDRESSES_T1'
感谢您的帮助!
推荐答案
您正在更新编写触发器的同一个表.你需要这样的东西:
You're updating the same table the trigger is written. You need something like this:
create or replace trigger "ADDRESSES_T1"
BEFORE
insert or update on "ADDRESSES"
for each row
begin
DECLARE
l_lat NUMBER;
l_lng NUMBER;
l_postcode VARCHAR2(8) := :NEW.POSTCODE;
BEGIN
brian.POSTCODE_TO_LAT_LNG_GM_API (l_postcode, l_lat, l_lng);
:new.location = SDO_GEOMETRY(2001, --SDO_GTYPE
8307, --SDO_SRID
SDO_POINT_TYPE(l_lng, --X lng
l_lat, --Y lat
null), --Z
null, --SDO_ELEM_INFO_ARRAY
null);
END;
