How to use variable in target database name for insert statement?

Question

I want to declare a server name and use this name in an insert statement. So far all i got is an error message.

declare @machine nvarchar(6);
declare @bar nvarch         


        

Answer 1

I've had this problem before and the only work around I found is dynamic sql

declare @machine nvarchar(6)
declare @bar nvarchar(3)
declare @sql varchar(2000)
set @machine = 'Name00'
set @bar = 'foo'


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

--print (@sql)
exec (@sql)
