SqlServer基础操作

先说创建表：

create table TblStudent(
tSid int identity(1,1) primary key,
tSName nvarchar(50),
tSGender nchar(1),
tSAddress nchar(500),
tSAge int,
tSClassId int,
tSBirthday datetime

)

create table TblClass(
tClass int identity(1,1) primary key,
tClassName nvarchar(50) not null
)

插入数据：

insert into 
TblStudent(tSName,tSGender,tSAddress,tSAge,tSClassId,tSBirthday)
values('成龙','男','中国香港','18','562214654','1970-11-12')

查看数据表：

select * from TblStudent

省略列名直接插入：

insert into TblStudent
values('刘德华','男','中国香港','18','1','1970-01-02')

向自动编号的列添加数据：

--向自动编号的表插入数据

set identity_insert TblClass on
insert into 
TblClass(tClass,tClassName)
values(500,'超级500班'
)
set identity_insert TblClass off

--更新语句 update 表名 set 列名1='值',列名2='值',... where 条件

update TblClass set tClassName = '二班' where tClass = 2
update TblClass set tClassName = '三班' where tClass = 3
update TblClass set tClassName = '四班' where tClass = 4

update TblStudent set tSName = tSName+'(男)' where tSGender = '男'

--删除delete from 表名 where 条件

delete from TblClass where tClass = 4
