下面通过图文并茂的方式给大家详解Mysql学习心得之插入、更新、删除记录。
插入记录
Insert[]into] tb1_name[(col_name,…..)]
自动编号的字段，可以用values default
Default 可以赋予默认值
INSERT USERS VALUES(NULL,'TOM','123',25,1);
Notice: Undefined index: CMSdown in /data/webroot/gcms/lib/Api/Open/Article.php on line 161

可以同时插入多条记录
INSERT users VALUES(DEFAULT,'TOM','123',3*7-5,1),(NULL,'ROSE',MD5('123'),DEFAULT,0);
Notice: Undefined index: CMSdown in /data/webroot/gcms/lib/Api/Open/Article.php on line 161

方法2
INSERT users SET username='Ben',password='456'; (但只能插入单条记录）
Notice: Undefined index: CMSdown in /data/webroot/gcms/lib/Api/Open/Article.php on line 161

单表更新
UPDATE users SET age =age-id ,sex=0;
Notice: Undefined index: CMSdown in /data/webroot/gcms/lib/Api/Open/Article.php on line 161
img/2015/08/19/142117_55d4205d6b9f0.png" alt="查看图片" />
UPDATE users SET age=age+10 WHERE id%2=0;
Id%2=0 （id字段除以2的余数为0）
Notice: Undefined index: CMSdown in /data/webroot/gcms/lib/Api/Open/Article.php on line 161

删除字段 delete
DELETE FROM users WHERE id =5;

再插入一条新记录id自动编号为6，而不是已删除的5
