Microsoft SQL Server/Database manipulation

Creation

To create a database, its files have to be defined:

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

Reading

Then to select it, it's either possible to set it at the beginning of the script:

USE MyDB;
SELECT * FROM MyTable;

or to call all the objects with their full path. Eg:

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

Backup

Restoration

If the database to restore doesn't exist on the destination server, it's necessary to create it empty first. In SSMS, with a right click on Databases, New database.

The process is a right click on the database to restore, and Restore the database, select the .bak.

Otherwise in SQL it gives:

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