Creating a database

Creating a database without specifying files

CREATE DATABASE mytest

Creating a database that specifies the data and transaction log files

CREATE DATABASE Sales
ON
( NAME = Sales_dat,
FILENAME = '''+ @data_path + 'saledat.mdf'',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 5 )
LOG ON
( NAME = Sales_log,
FILENAME = '''+ @data_path + 'salelog.ldf'',
SIZE = 5MB,
MAXSIZE = 25MB,
FILEGROWTH = 5MB )'
);
GO

Creating a database by specifying multiple data and transaction log files

'CREATE DATABASE Archive
ON
PRIMARY
(NAME = Arch1,
FILENAME = '''+ @data_path + 'archdat1.mdf'',
SIZE = 100MB,
MAXSIZE = 200,
FILEGROWTH = 20),
( NAME = Arch2,
FILENAME = '''+ @data_path + 'archdat2.ndf'',
SIZE = 100MB,
MAXSIZE = 200,
FILEGROWTH = 20),
( NAME = Arch3,
FILENAME = '''+ @data_path + 'archdat3.ndf'',
SIZE = 100MB,
MAXSIZE = 200,
FILEGROWTH = 20)
LOG ON
(NAME = Archlog1,
FILENAME = '''+ @data_path + 'archlog1.ldf'',
SIZE = 100MB,
MAXSIZE = 200,
FILEGROWTH = 20),
(NAME = Archlog2,
FILENAME = '''+ @data_path + 'archlog2.ldf'',
SIZE = 100MB,
MAXSIZE = 200,
FILEGROWTH = 20)'
);
GO
 
Creating a database that has filegroups

CREATE DATABASE Sales
ON PRIMARY
( NAME = SPri1_dat,
FILENAME = '''+ @data_path + 'SPri1dat.mdf'',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 15% ),
( NAME = SPri2_dat,
FILENAME = '''+ @data_path + 'SPri2dt.ndf'',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 15% ),
FILEGROUP SalesGroup1
( NAME = SGrp1Fi1_dat,
FILENAME = '''+ @data_path + 'SG1Fi1dt.ndf'',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 5 ),
( NAME = SGrp1Fi2_dat,
FILENAME = '''+ @data_path + 'SG1Fi2dt.ndf'',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 5 ),
FILEGROUP SalesGroup2
( NAME = SGrp2Fi1_dat,
FILENAME = '''+ @data_path + 'SG2Fi1dt.ndf'',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 5 ),
( NAME = SGrp2Fi2_dat,
FILENAME = '''+ @data_path + 'SG2Fi2dt.ndf'',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 5 )
LOG ON
( NAME = Sales_log,
FILENAME = '''+ @data_path + 'salelog.ldf'',
SIZE = 5MB,
MAXSIZE = 25MB,
FILEGROWTH = 5MB )'
);

Attaching a database

'CREATE DATABASE Archive
ON (FILENAME = '''+ @data_path + 'archdat1.mdf'')
FOR ATTACH');
GO

create function

create function myfuns(@x int) returns char(10)
as
begin
declare @xx char(10)
select @xx = nam from Table_1 where id= @x
return @xx
end

create stored procedure

create proc myproc
