创建Users表并且插入10000条数据,script如下:
use DBDemo go -- 判断如果Users表已经存在,则drop Users表 if exists(select * from sysobjects where name='Users') drop table Users -- 创建Users表 create table Users ( Id int primary key identity(1,1), Username varchar(8000) not null, Password varchar(10) not null ) --插入数据 declare @id int, @username varchar(100), @password varchar(10) set @id=0 set @username='user' set @password='abc123_' while @id<10000 begin insert into Users(Username,Password) values (@username+convert(varchar(100),@id),@password) -- int转string也可以用cast(@id as varchar(100) set @id=@id + 1 end
