To join tables from two different databases, we can use fully qualified names of the tables in this format [databasename].[owner].[tablename].
SELECT ac.AutoId, ac.FullName, pd.Age
FROM [IHaveBeenRenamed].[dbo].Accounts ac
[SqlHowTo].[dbo].PersonalDetails pd ON ac.AutoId = pd.PersonalDetailsId
In the above query, we are joining Accounts table of
IHaveBeenRenamed database table and PersonalDetails of
SqlHowTo table on AutoId of Accounts table and PersonalDetailsId of PersonalDetails table.
