问题 Ok, the problem is that there's a merger or join that needs to be done on 2 tables. One has file content stored as an [image] type or varbinary(max), the other has the file content stored as a hex string. if I upload the same content into both tables the content as string (bytearray to string) would look like like this...

I have an application where I allow users to upload files, mainly PDF and Word documents. These files are stored in a varbinary field in the database. For what it is worth, I need to have these files available regardless of how the user is accessing the application, via Web or Windows Forms application or any other Presentation layer. Is there a way to search the raw text contents of these fields? For example, if I upload a resume, I would like the user to be able to search C# and be able to look in the contents of varbinary field for the specified text. Also, if there is a better strategy for

I was reading on internet these statements about SQL Server data types: VARBINARY(MAX) - Binary strings with a variable length can store up to 2^31-1 bytes. IMAGE - Binary strings with a variable length up to 2^31-1 (2,147,483,647) bytes. Is there a really big technical difference between VARBINARY(MAX) and IMAGE data types? If there is a difference: do we have to customize how ADO.NET inserts and updates image data field in SQL Server? gbn They store the same data: this is as far as it goes. " image " is deprecated and has a limited set of features and operations that work with it. varbinary

I am saving files (any type ) in a SQL table, using a varbinary(max) , I find out that the max usage of this datatype is 8000, but what does the 8000 mean? The online documentation says that is 8000 bytes. Does that mean that the maximum size of the file to be save there is 8000/1024 = 7.8125 KB? I start testing and the maximum file that I can store is 29.9 MB. If I choose a larger file a get a SQLException. String or binary data would be truncated. The statement has been terminated.

A while ago I asked a question about hierarchy/version number sorting in SQL Server. ( How Can I Sort A 'Version Number' Column Generically Using a SQL Server Query ). Among the answers that were submitted was this link to a TSQL Coding challenge with much the same puzzle . In the SQL2000 solution the author demonstrated a two variations, one using and returning a varchar and the other varbinary. The author explains THAT he is doing this without explaining WHY. So, my question is really, what main differences/advantages (if any) of the difference in approach? I.e. why use a varbinary instead

How can I get fluent nhibernate to create a varbinary field in a sql server 2005 table that uses a field size of varbinary(max)?
