Answer 1

You will have to use dynamic sql for this. Try the following:

declare @machine nvarchar(6);
declare @bar nvarchar(3);
declare @query nvarchar(4000)


set @machine = 'Name00';
set @bar = 'foo'

set @query = 'insert into ' + @machine + '.dbname.dbo.table (column1, column2) select (column1, column2) from table where column1 = ''' + @bar + ''''

execute dbo.sp_executesql @query
