大家好，我是考100分的小小码 ，祝大家学习进步，加薪顺利呀。今天说一说oracle创建触发器（例：当有操作x_yonghu表指定字段并且字段有修改时，插入日志表）,希望您对编程的造诣更进一步.
最近总发现用户表一些数据被删了，找不到原因，后面通过创建触发器来排查，当有操作x_yonghu表时，记录下来插入日志表中。
create or replace trigger trg_x_yonghu_log_aft_modify after update OF shouji, zigezhenghao,zidianshurufa,shurufa on x_yonghu for each row declare pri_sqlcode varchar2(100); pri_sqlerrm varchar2(4000); pri_username varchar2(50); pri_ip varchar2(100); pri_host varchar2(200); pri_type varchar2(100); begin pri_username := sys_context("userenv", "session_user"); pri_ip := sys_context("userenv", "ip_address"); pri_host := sys_context("userenv", "host"); pri_type := "update"; case when updating("shouji") or updating("zidianshurufa") or updating("shurufa") then if :new.shouji != :old.shouji or :new.zidianshurufa != :old.zidianshurufa or :new.shurufa != :old.shurufa then insert into x_yonghu_log (yonghuid_old, yiyuanid_old, zidianshurufa_old, shurufa_old, shouji_old, zigezhenghao_old, yonghuid_new, yiyuanid_new, zidianshurufa_new, shurufa_new, shouji_new, zigezhenghao_new, modify_host, modify_ip, modify_username, modify_type) values (:old.yonghuid, :old.yiyuanid, :old.zidianshurufa, :old.shurufa, :old.shouji, :old.zigezhenghao, :new.yonghuid, :new.yiyuanid, :new.zidianshurufa, :new.shurufa, :new.shouji, :new.zigezhenghao, pri_host, pri_ip, pri_username, pri_type); end if; end case; exception when others then begin pri_sqlcode := sqlcode; pri_sqlerrm := sqlerrm; insert into x_yonghu_log (modify_username, modify_ip, modify_host, modify_type, errormsg_sqlcode, errormsg_sqlerrm) values (pri_username, pri_ip, pri_host, pri_type, pri_sqlcode, pri_sqlerrm); end; end;
