創(chuàng)建table：
1.create table tbmeetmgrinfo(
2. id number primary key, /*主鍵，自動增加 */
3. huiyishi number, /*會議室編號 */
4. STARTTIME varchar2(30), /*會議開始時間 */
5. ENDTIME varchar2(30), /*會議結(jié)束時間 */
6. CREATETIME varchar2(30), /*會議創(chuàng)建日期 */
7. STOPTIME varchar2(30), /*會議起止日期*/
8. xunhuaimoshi number /*會議循環(huán)模式1為單周、3為每月、4為每季度 、0為一次性會議*/
9.);
10.
11.--創(chuàng)建自動增長序列
12.create sequence tbmeetmgrinfo_tb_sequence
13. minvalue 1 --最小值
14. maxvalue 9999999999999999999999999 --最大值
15. increment by 1 --增加量為1
16. start with 1 /* 從1開始 */
17.
18. insert into tbmeetmgrinfo values(tbmeetmgrinfo_tb_sequence.nextval,2,'12:00','13:00','2011-05-10','2011-05-11',1)
19.
20. select * from tbmeetmgrinfo
創(chuàng)建觸發(fā)器：
1.create or replace trigger biufer_tbmeetmgr_CHANGETIME
2. before insert or update or delete
3. of CHANGETIME
4. on tbmeetmgr
5. for each row
6.begin
7. -- 調(diào)用存儲過程
8. hzwmeetmgr;
