SQLServer 数据库一些基本操作的脚本。

use master
go

create database TestDB
on primary

	filename='F:\DB\TestDB_log.mdf',--绝对路径
	size=10MB,--数据库初始大小
	filegrowth=5MB --数据文件增长量
	--上面四个文件缺一不可
)
log on

	filename='F:\DB\TestDB_log.ldf',
	size=5MB,
	filegrowth=2MB
)

go

use master
go

if exists(select * from sysdatabases where name = 'TestDB01') 
drop database TestDB01 --删除就不能恢复了，一般测试阶段数据库内没有数据的时候用。
