Transfer SQL 2005 Query result

Hi All,

In my web application (VS2008), I have to transfer result of a query in MS SQL 2005 from one MS SQL instance to another using a portable memory device (both servers are in different networks). The query results include images stored in varbinary(max) fields and varchar fields.

I looked at saving the query results in XML Files, Excel, and even Access 2007. Typical issue is handling of varbinary data. My research suggest that there is conversion issue between varbinary(max) in SQL 2005 and OLE Object in Access.

What would be the best way here? If any one has worked on this before, can you please share experience/code snippets?

How about converting the VARBINARY(Max) as a Base64 string and saving as string in other OLEDB databases?

As I understand, you are suggesting a loop through the dataset populated by the query to fetch each varbinary value and convert it to Base64 string and save it in the OLEDB database. I also convert this back to the varbinary, when I upload this to SQL Server. Is it possible for you to give an example?

Well, I just got the SQL way of encoding varbinary(max) to / from base64 string. Thanks for the suggesting this approach..... Intends to get the query result as base64 string instead of varbinary and they save is as xml file through a datatable..........
