1右键“数据库”点击“新建数据库”即可
2用sql语言创建此处以创建数据库DB_test为例代码如下
use master;go--检查在当前服务器系统中的所有数据里面是否有该数据库
IF EXISTS(SELECT * FROM sysdatabases WHERE NAMEDB_test)
--如果有删除该数据库DROP DATABASE DB_test
-- 创建该数据库CREATE DATABASE DB_test ---DB_Yun 数据名称ON PRIMARY(NAMEDB_test, --主数据文件的逻辑名FILENAMED:developsqldataDB_test.mdf, --主数据文件存储位置SIZE16MB, --主数据文件的初始大小FILEGROWTH8MB, --每次增容时增加的容量大小MAXSIZEUNLIMITED --增量速度 unlimited无限制)LOG ON( NAMEDB_test.LDF, --日志文件FILENAMED:developsqldataDB_test.ldf, --日志文件存储位置SIZE16MB, --日志文件初始大小FILEGROWTH8MB, --日志文件每次增加的容量大小MAXSIZEUNLIMITED3创建成功 2.进行数据的导入
