Question

我有这样的代码：

create trigger audit_trigg_Test After insert on LOG 
for each row when(new.j='PR' and new.ds='FB') execute procedure ABC()
     when(new.j='PR' and new.ds='LNK')  execute procedure XYZ()


create or replace function ABC() returns trigger as $$
begin
--Stuff
end

create or replace function XYZ() returns trigger as $$
begin
--Stuff
end

触发器应该基于条件

对存储过程起作用

when(new.j='PR' and new.ds='FB') execute procedure ABC()
         when(new.j='PR' and new.ds='LNK')  execute procedure XYZ()

我该怎么做？

Answer 1

为此，您需要定义两个单独的触发器：

CREATE TRIGGER audit_trigg_Test_ABC
AFTER INSERT ON log 
FOR EACH ROW WHEN (NEW.j = 'PR' AND NEW.ds = 'FB') EXECUTE PROCEDURE ABC();

CREATE TRIGGER audit_trigg_Test_XYZ
AFTER INSERT ON log 
FOR EACH ROW WHEN (NEW.j = 'PR' AND NEW.ds = 'LNK') EXECUTE PROCEDURE XYZ();

您可以使用WHEN子句来确定是否触发了触发器，但您无法有条件地选择要调用的触发器函数。

根据条件postgres执行存储过程
