SQL server 2008R2中怎么直接修改表内数据

Posted 2023-05-08

1、首先打开数据库查询语句，输入查询语句先查询一下数据表中的数据内容。

2、输入查询语句，:Select * from Student，输入完毕之后选择全部内容，选择执行按钮，执行SQL语句。

3、执行完毕之后，在Student表中的第四行数据（StudentName中的“崔”），这里需要把它修改为“亮亮”。

4、在你的数据表上，用鼠标右击选择里面的“编辑前200行”。

5、编辑完毕之后，可以在查询表中看到你的所有数据，如下图中红线内容。

6、这里直接选择里面的内容把它修改成“亮亮”。

7、修改完毕之后这里选择右击内容，选择里面的执行。

8、执行完毕之后，同样的方式，用数据查询语句查询数据，这里可以在如下图中看到已经成功的修改了数据内容。

参考技术A 在SQL Server Management Studio的对象管理器中，找到你要输入数据的表，按鼠标右键，选择“编辑TOP 200行（Edit Top 200 Rows）”,在右边的表格中可以直接编辑。
但如果需要编辑更多数据，例如1000行，此时可点击工具栏中sql调出sql窗口，其中显示select top 200....，可将200改为1000. 以此类推。本回答被提问者采纳 参考技术B 你用sqlserver management连上服务器，然后就可以改啦
