Update 语句用于修改表中的数据。
UPDATE 表名称 SET 列名称 = 新值 WHERE 列名称 = 某值
| LastName | FirstName | Address | City |
|---|---|---|---|
| Gates | Bill | Xuanwumen 10 | Beijing |
| Wilson | Champs-Elysees |
我们为 lastname 是 "Wilson" 的人添加 firstname：
UPDATE Person SET FirstName = ‘Fred‘ WHERE LastName = ‘Wilson‘
| LastName | FirstName | Address | City |
|---|---|---|---|
| Gates | Bill | Xuanwumen 10 | Beijing |
| Wilson | Fred | Champs-Elysees |
我们会修改地址（address），并添加城市名称（city）：
UPDATE Person SET Address = ‘Zhongshan 23‘, City = ‘Nanjing‘ WHERE LastName = ‘Wilson‘
| LastName | FirstName | Address | City |
|---|---|---|---|
| Gates | Bill | Xuanwumen 10 | Beijing |
| Wilson | Fred | Zhongshan 23 | Nanjing |
