oracle触发器加条件判断,如果某个字段,isnode=0,那么不执行下面的方法,数据如下: create or replace trigger tr_basestation_insert_emp before insert on BJLT.BASESTATION REFERENCING NEW AS new_val OLD AS old_val --在这里设置名字,然后可引用新值,旧值 for each row ) declare --local variables here begin i
因为项目需要,有一个已经写好的Java程序,想要在Oracle某个表的触发器中调用,以使得每次数据更新时,调用这个JAVA程序,来修改后台某个数据. 现将过程记录如下: 1.编写JAVA程序 public class Main { public static void modify(String statTime) { String datas = "/var/spool/cron/oracle"; File data = new File(datas); StringBuffer b
create or replace trigger TRI_FC83_INSERT before insert ON FC83 FOR EACH ROW declare PRAGMA AUTONOMOUS_TRANSACTION; BEGIN :'; delete from fc83 where afc001 = :new.afc001 and afa031 = :new.afa031 and afc210 = :new.afc210; commit; END TRI_FC83_INSERT;
连续创建多个Oracle触发器失败,单个创建才成功的解决方法 1.当我连续执行创建多个触发器时,总是报编译通过,但存在警告或错误.如下: create or replace trigger tr_advert before insert on jcms_advert for each row begin select seq_advert.nextval into :new.id from dual; end; create or replace trigger tr_adv
SQL Server 1创建触发器 GO BEGIN IF (object_id('WMY', 'tr') is not null) DROP trigger WMY END; GO CREATE TRIGGER WMY ON Student Instead of INSERT AS BEGIN INSERT INTO Student (number,name) VALUES (1205,'角色2'); END; --Begin 与end相当于{},是一个语句块,可有可无此处为演示所用 --ON
oracle触发器中增删改查本表 (1)只有before insert触发器中才可以查询或更新本表 create or replace trigger tri_test_ins before insert on test for each row declare v_cnt integer; begin select count(*) into v_cnt from test; dbms_output.put_line('test count:'||to_char(v_cnt)); u
