创建table：

create table tbmeetmgrinfo(

id number primary key, /*主键，自动增加 */

huiyishi number, /*会议室编号 */

STARTTIME varchar2(30), /*会议开始时间 */

ENDTIME varchar2(30), /*会议结束时间 */

CREATETIME varchar2(30), /*会议创建日期 */

STOPTIME varchar2(30), /*会议起止日期*/

xunhuaimoshi number /*会议循环模式1为单周、3为每月、4为每季度 、0为一次性会议*/

);

--创建自动增长序列

create sequence tbmeetmgrinfo_tb_sequence

minvalue 1 --最小值

maxvalue 9999999999999999999999999 --最大值

increment by 1 --增加量为1

start with 1 /* 从1开始 */

insert into tbmeetmgrinfo values(tbmeetmgrinfo_tb_sequence.nextval,2,'12:00','13:00','2011-05-10','2011-05-11',1)

select * from tbmeetmgrinfo

创建触发器：

create or replace trigger biufer_tbmeetmgr_CHANGETIME

before insert or update or delete

of CHANGETIME

on tbmeetmgr

for each row

begin

-- 调用存储过程

hzwmeetmgr;

end;

存储过程：

CREATE OR REPLACE PROCEDURE hzwmeetMgr is

meetId number; --会议室编号

strSta varchar2(30); --会议开始时间

strEnd varchar2(30); --会议结束时间

strCreate varchar2(30); --会议创建日期

strOver varchar2(30); --会议终止日期(循环终止时期)

strOverSql varchar2(30); --存入临时表中的终止日期

varInt number; --会议创建日期到终止日期相差天数

varSubTime varchar2(30); --循环日期

varMonths number;

TYPE c_time IS REF CURSOR; --创建游离标记

vrec c_time;

yearY varchar2(10); --日期年部分

monthsM varchar2(10);--日期月部分(终止入库时间)
