varbinary

I'm trying to serve image data stored in a VARBINARY(MAX) field in the database using ASP.Net. Right now, the code is filling a data table, then pulling the byte array out of the DataRow and pushing the byte array into the response. I'm wondering if there's a way to more-or-less stream the data from the SQL Server into the response without having to marshal around these huge byte arrays (since the images are large, they cause OutOfMemoryExceptions). Is there a class/mechanism for that? The current code looks more or less like: DataTable table = new DataTable(); SqlDataAdapter adapter = new

I have some varbinary data stored in a table in MS Sql Server 2005. Does anyone have SQL code that takes a query as input (lets say the query guarantees that a single column of varbinary is returned) and outputs the bytes to disk (one file per row?) I'm sure this has been asked a thousand times before, but Googling comes up with mostly .net solutions. I want an SQL solution. The BCP approach does not work for me. The bytes it writes to disk cannot be deserialized back to the .net objects I stored. This means that the bytes on disk aren't equivalent to what's stored. Perhaps BCP is writing some

I want to do conversion in T-SQL from a varbinary type to string type Here is an example : First I got this varbinary 0x21232F297A57A5A743894A0E4A801FC3 And then I want to convert it to 21232f297a57a5a743894a0e4a801fc3 How to do this? Try: DECLARE @varbinaryField varbinary(max); SET @varbinaryField = 0x21232F297A57A5A743894A0E4A801FC3; SELECT CONVERT(varchar(max),@varbinaryField,2), @varbinaryField UPDATED: For SQL Server 2008 I know this is an old question, but here is an alternative approach that I have found more useful in some situations. I believe the master.dbo.fn_varbintohexstr function
