Database names within an instance must be unique.

Different instance names with same database name on same machine is possible with different database file locations.

Or different instances with same file location but same database file names.;-)

You cant host 2 DB's with the same name in the same SQL instance, even if you have different filenames.
Each DB name has to be unique.

thanks everyone ...i know i cant have two dbs with same name under same instance...i was looking is there a way setup some alias..or something else..

Reminds me of the Monty Python "Is your name not Bruce" skit, where everyone was named Bruce, and they renamed newcomers to avoid confusion. Can't have a "Michael" running around in the middle of a bunch of Bruces...might cause some confusion.
I'd like to hear exactly why you think you need multiple databases named the same; i'm having trouble visualizing any need for it.
as an example, all my applications get the db info from a connection string built from values in a .config file, or an ini file, or from some registry entry.
they do not care about the name of the database the connect to, just that they have a valid connection.
why would you need to have a specific db name?

They aren't the same same. "SSISDB" and "SSSISDB"; there's an extra S.
SQL Server is quite happy to accept "stupid" names for objects. For example, if I run the following:USE master;
GO
DECLARE @sql nvarchar(MAX);
SET @sql = N'CREATE DATABASE [Foolishness] ON
PRIMARY (NAME = ''Foolishness'', FILENAME = N''C:\Program Files\Microsoft SQL Server\MSSQL11.SANDBOX\MSSQL\DATA\Foolish1.mdf'')
LOG ON (NAME = N''Foolishness_log'', FILENAME = N''C:\Program Files\Microsoft SQL Server\MSSQL11.SANDBOX\MSSQL\DATA\Foolish1_log.ldf'');';
EXEC sp_executesql @sql;
SET @sql = N'CREATE DATABASE [Foolish' + NCHAR(10) + N'ness] ON
PRIMARY (NAME = ''Foolishness'', FILENAME = N''C:\Program Files\Microsoft SQL Server\MSSQL11.SANDBOX\MSSQL\DATA\Foolish2.mdf'')
LOG ON (NAME = N''Foolishness_log'', FILENAME = N''C:\Program Files\Microsoft SQL Server\MSSQL11.SANDBOX\MSSQL\DATA\Foolish2_log.ldf'')';
EXEC sp_executesql @sql;
GO
If you then refresh the Object Explorer, you'll see 2 "same" named databases:
Of course, they are not the same, as one has a line break in it.--Clean up
DECLARE @sql nvarchar(MAX);
SET @sql = N'DROP DATABASE Foolishness;'
EXEC sp_executesql @sql;
SET @sql = N'DROP DATABASE [Foolish' + NCHAR(10) + N'ness];'
EXEC sp_executesql @sql;

I suspect one of those databases has a special character in there. I bet if you ran the following SQL you would get different value for BinaryName:
SELECT [Name], CONVERT(varbinary,[name]) AS BinaryName
FROM sys.databases;SQL Server is quite happy to accept "stupid" names for objects. For example, if I run the following:
USE master;
GODECLARE @sql nvarchar(MAX);
SET @sql = N'CREATE DATABASE [Foolishness] ON PRIMARY (NAME = ''Foolishness'', FILENAME = N''C:\Program Files\Microsoft SQL Server\MSSQL11.SANDBOX\MSSQL\DATA\Foolish1.mdf'')
LOG ON
(NAME = N''Foolishness_log'', FILENAME = N''C:\Program Files\Microsoft SQL Server\MSSQL11.SANDBOX\MSSQL\DATA\Foolish1_log.ldf'');';
EXEC sp_executesql @sql;SET @sql = N'CREATE DATABASE [Foolish' + NCHAR(10) + N'ness]
ON PRIMARY (NAME = ''Foolishness'', FILENAME = N''C:\Program Files\Microsoft SQL Server\MSSQL11.SANDBOX\MSSQL\DATA\Foolish2.mdf'')
LOG ON
( NAME = N''Foolishness_log'', FILENAME = N''C:\Program Files\Microsoft SQL Server\MSSQL11.SANDBOX\MSSQL\DATA\Foolish2_log.ldf'')';

Hi
ran suggested query and found binary name is different. how can i understand correct differences.

I've editted my post since then, as I didn't initially notice. There's an extra S there.
