INSERT INTO 语句用于向表格中插入新的行。
语法
<strong><code style="padding:0px; font-family:Monaco,'Andale Mono','Courier New',monospace; font-size:12px; color:inherit; background-color:transparent; border:0px">INSERT INTO 表名称 VALUES (值1, 值2,....)</code></strong>
我们也可以指定所要插入数据的列：
<strong><code style="padding:0px; font-family:Monaco,'Andale Mono','Courier New',monospace; font-size:12px; color:inherit; background-color:transparent; border:0px">INSERT INTO table_name (列1, 列2,...) VALUES (值1, 值2,....)</code></strong>
Update 语句用于修改表中的数据。
语法：
<strong><code style="padding:0px; font-family:Monaco,'Andale Mono','Courier New',monospace; font-size:12px; color:inherit; background-color:transparent; border:0px">UPDATE 表名称 SET 列名称 = 新值 WHERE 列名称 = 某值</code></strong>
DELETE 语句用于删除表中的行。
语法
<strong><code style="padding:0px; font-family:Monaco,'Andale Mono','Courier New',monospace; font-size:12px; color:inherit; background-color:transparent; border:0px">DELETE FROM 表名称 WHERE 列名称 = 值</code></strong>
删除某行
"Fred Wilson" 会被删除：
<strong><code style="padding:0px; font-family:Monaco,'Andale Mono','Courier New',monospace; font-size:12px; color:inherit; background-color:transparent; border:0px">DELETE FROM Person WHERE LastName = 'Wilson' </code></strong>
删除所有行
可以在不删除表的情况下删除所有的行。这意味着表的结构、属性和索引都是完整的：
<code style="padding:0px; font-family:Monaco,'Andale Mono','Courier New',monospace; font-size:12px; color:inherit; background-color:transparent; border:0px"><strong>DELETE FROM table_name</strong>或者：<strong>DELETE * FROM table_name</strong></code>
