Create database

Create NORTHWIND database

1> use master
2> go
1> create database [NORTHWIND]
2>     on ( name        = N'NORTHWIND_dat',
3>          filename    = N'C:\\mssql\\data\\iDEFAULT\\NORTHWIND\\NORTHWIND_01.mdf' ,
4>          size        = 10,
5>          filegrowth  = 1,
6>          maxsize     = 1024
7>        )
8> log on ( name        = N'NORTHWIND_log',
9>          filename    = N'C:\\mssql\\tlog\\iDEFAULT\\NORTHWIND\\NORTHWIND_01.ldf' ,
10>         size        = 10,
11>         filegrowth  = 1,
12>         maxsize     = 1024
13>        )

1> select dbid, left( name, 10) name
2>   from sysdatabases
3>  where name = 'NORTHWIND'
