Binary and varbinary. How they compare to DB2's blob I don't know.|||Binary and varbinary are "fixed length" in the same sense as char and
varchar. If you want to store a large amount of binary data, you
probably want the "image" type.|||i just checked the sql server docs.
it seems image type is DB2 blobs equivalent|||(causacn@.gmail.com) writes:

The "classic" answer in this regard is the image data type, with its
cousins text and ntext for character data.

But in the new version of SQL Server, SQL 2005, just recently released,
there is a new data type: varbinary(MAX) as well as varchar(MAX) and
nvarchar(MAX). If you are on SQL 2005, you should use the MAX data types,
as they are lot easier to deal with than image/text/ntext.
