试过了不行。触发器主体如下：其中表名和关键字冲突的是“interface”Declare
ls_menuid VarChar2(32);
ls_windowid VarChar2(32);--角色菜单删除的同时删除角色菜单按钮。
Begin
ls_menuid := :old.menuid;
select interfaceid
into ls_windowid
from "interface"
where menuid = ls_menuid;
delete from role_button
where windowid = ls_menuid;
End;
ls_menuid VarChar2(32);
ls_windowid VarChar2(32);--角色菜单删除的同时删除角色菜单按钮。
Begin
ls_menuid := :old.menuid;
select interfaceid
into ls_windowid
from "interface"
where menuid = ls_menuid;
delete from role_button
where windowid = ls_menuid;
End;
ls_menuid VarChar2(32);
ls_windowid VarChar2(32);--角色菜单删除的同时删除角色菜单按钮。
Begin
ls_menuid := :old.menuid;
select interfaceid
into ls_windowid
from "interface"
where menuid = ls_menuid;
delete from role_button
where windowid = ls_windowid;
End;
