mysql設定某列資料自增1 及設定後insert寫法
+--------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------+--------------+------+-----+---------+----------------+ | no | int(11) | NO | PRI | NULL | | | name | varchar(50) | YES | | NULL | | | src | varchar(100) | YES | | NULL | | | goods | int(11) | YES | | 0 | | | clicks | int(11) | YES | | 0 | | | date | datetime | YES | | NULL | | | author | varchar(50) | YES | | NULL | | | intro | varchar(100) | YES | | NULL | | +--------+--------------+------+-----+---------+----------------+
如令no資料自增，則：
alter table pics modify no int AUTO_INCREMENT;
設定自增後insert寫法：自增列資料輸入0或null即可，如：
insert pics values(0,"wugui","pic/s",0,0,"2018-05-26","ss","ss");
insert pics values(null,"wugui","pic/s",0,0,"2018-05-26","ss","ss");
select * from pics;
