1、在企业管理器里,在右边的树展开,找到你的库,展开,单击表,在左边的屏幕上就有库中所有的表,选择你要修改的表,右键,选择打开表/查询,在出现的SQL语句中补充完整条件,执行该语句,找到你要修改的记录,在下面结果窗口修改,修改完鼠标点击一下窗口其它地方,关闭即保存
2、在SQL查询分析器里写UPDATE set脚本语句来修改

可通过一下的存储过程来实现的。以下代码在SQL Server 2000 + SP4中调试通过。
if exists(select * from sysobjects where lower(name)=lower('up_AddCol4Obbr') and xtype='P')
drop procedure up_AddCol4Obbr
go
create procedure up_AddCol4Obbr
@strTable nvarchar(100),
@strColName nvarchar(100),
@strType nvarchar(100)
as
begin
declare @strSQL nvarchar(1000)
if not exists(select * from syscolumns where lower(name)=lower(@strColName) and id in (select id from sysobjects where lower(name)=lower(@strTable) ))
begin
select @strSQL = N'alter table ' + @strTable + ' add ' + @strColName + ' ' + @strType
exec sp_executesql @strSQL
end
else
begin
select @strSQL = N'alter table ' + @strTable + ' alter column ' + @strColName + ' ' + @strType
exec sp_executesql @strSQL
end
end
go
if exists(select * from sysobjects where lower(name)=lower('up_CheckCols4Obbr') and xtype='P')
drop procedure up_CheckCols4Obbr
go
create procedure up_CheckCols4Obbr

打开查询分析器,SQL的命令语句都在那里输入的
创建名字为student的表格,括号内为其列名:
create table student(Sno char(10),Sname char(2),Ssex char (2),Sage char (2),Sdept char(2))
在student表格中插入数据:
INSERT INTO Student(Sno,Sname,Ssex,Sage,Sdept) VALUES('200215121','李勇','男' ,19,'CS');
删除学号为200215121的学生记录:
delete from student where sno=200215121
修改表格名字:
sp_rename 'student','stu'
.....等等........还有很多很多~~~~自己在以后进一步学习中漫漫体会吧!

安装了SQL Server 2000 就可以使用界面化操作了。
很简单的。
