if you need to access a table from another database use the full naming


select *
from   db2.dbo.table

Remember that if you do use this approach

set @mysqlcmd = 'USE ' + @DBNameWithSimpleLog
EXEC (@mysqlcmd)

Then the context is only changed for the duration of the EXEC, not for anything after that.
