I have written a T-SQL script that migrates some data from one database to another.
At the moment I am doing that by use of dynamic sql.

For example see the following code:

Declare @sqlquery nvarchar(4000)
SET @sqlquery = N'SELECT * from ' + @LinkServerName + @SourceDatabaseName + '.dbo.Table'
EXEC @sqlquery

In this example @LinkServerName is a nvarchar variable that stores the name of the linked server for the SQL Server that contains the source database. @SourceDatabaseName is a nvarchar variable that stores the name of the source database.

I don´t like that way. I would prefer the following code:

SELECT * from @SourceDatabase.dbo.Table

Is that possible?

Thank you in advance.

    Second approach is incorrect, first one is the correct one. For more information check this other question here at stackoverflow how-to-use-variable-for-database-name-in-t-sql
