1.Oracle存储过程实例 /*不带任何参数存储过程(输出系统日期)*/ CREATE OR REPLACE PROCEDURE output_date IS BEGIN DBMS_OUTPUT.PUT_LINE(SYSDATE); END output_date; /*带参数in和out的存储过程*/ CREATE OR REPLACE PROCEDURE get_username(v_id IN NUMBER,v_username OUT VARCHAR2) AS BEGIN SELECT
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
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
