Microsoft SQL Server/Database manipulation

創建數據庫

創建的每個數據庫都會創建相應的文件：

• Master Database File (.mdf)
• Log Database File (.ldf)

CREATE DATABASE [MyDB] ON  PRIMARY 
( NAME = N'MyDB', FILENAME = N'D:\DATASQL\MSSQL10.MSSQLSERVER\MSSQL\DATA\MyDB.mdf' , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N'MyDB_log', FILENAME = N'D:\DATASQL\MSSQL10.MSSQLSERVER\MSSQL\DATA\MyDB_log.ldf' , MAXSIZE = 2048GB , FILEGROWTH = 10%)
GO

讀取

顯式指明數據庫:

USE MyDB;
SELECT * FROM MyTable;

或使用全路徑:

SELECT * FROM [MyDB].[dbo].[MyTable];

恢復

RESTORE DATABASE MyDB
FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.SQLEXPRESS\MSSQL\Backup\2016-02-16-MyDB.bak'
WITH REPLACE
