Extracting binary data from SQL Server
In this recipe, we will extract the binary content from SQL Server and save it back to individual files in the filesystem.

In addition to our
SampleBLOB table, we will create an empty table with a single
VARBINARY(MAX) table. We will use this to facilitate the creation of a format file we need to export binary data out of SQL Server using bcp:
USE SampleDB GO IF OBJECT_ID('EmptyBLOB') IS NOT NULL DROP TABLE EmptyBLOB GO CREATE TABLE EmptyBLOB ...
