轻松接触几个SQL Server数据库的简单示例

create table teachers(id int primary key not 
null identity(10000,100),tea_name varchar(50),
tea_age int default 20)
create procedure insert1000teachers
as
 declare @tea_name varchar(50)
 declare @tea_age int
 declare @index int
 declare @count int
 set @index=1
 set @count=100
while @index<@count
begin
 set @tea_age=30*rand()
 set @tea_name='teacher'
 set @tea_name=@tea_name+convert(varchar,@index)
 insert into teachers(tea_name,tea_age)
 values(@tea_name,@tea_age)
 set @index=@index+1
end

create database test1

add 
file

)

alter database test1
add 
filegroup filegroup1

alter database test1
add file

to filegroup filegroup1

更改字段名：sp_rename 'teachers.tea_name','tea_name1','column'
更改表名：sp_rename 'dbo.teachers','teachers1'
