SQL Azure database to SQL Azure database communication supported?

Question

We have a requirement to perform SQL Azure to SQL Azure database communication for a client that we are working with. 

 

We believe that this is unsupported.  To prove this we setup two SQL Azure databases (1 + 2) under the same SQL Azure server.  When we try to query one from the other using a simple TSQL statement, for example:

 

SELECT * FROM "[e-mail]”.Database2.dbo.Orders

 

We get the following error:

 

Msg 40515, Level 16, State 1, Line 1

Reference to database and/or server name in 'XXXXX.database.windows.net.Database2.dbo.Orders' is not supported in this version of SQL Server.

 

We were wondering if this is feature is in the SQL Azure road map to be supported and if so when will this be?

Hello John,

This is not possibe, SQL Azure don't support three- and/or four part qualifier, you can' select data from a different database, only from that one you are connected to.
