Binary Large Objects (BLOB) data can be a graphical image, a pdf document, a music file or any of a wide range of data types, which can generally be saved into a SQL Server database.
As part of a series of investigations I’m currently performing within SQL Server, I have looked at how BLOB data can be saved and retrieved.
Saving the data is reasonably simple. Retrieving it, less so….

Continuing my series of XML articles I’m going to move from XML RAW to XML AUTO with a handful of examples that share features between the two. Continue reading
Introduction
Most systems that I have worked with make use of the XML data type. I don’t find it to be the most intuitive data type to work with but most aspects of it can be built upon from a few basic examples. This will be part of a developing series that will cover XML and JSON. Continue reading
