MySQL Connector/NET Developer Guide
      One common use for MySQL is the storage of binary data in
      BLOB columns. MySQL supports four
      different BLOB data types: TINYBLOB,
      BLOB, MEDIUMBLOB, and
      LONGBLOB, all described in
      The BLOB and TEXT Types and Data Type Storage Requirements.
    
      Data stored in a BLOB column can be accessed
      using MySQL Connector/NET and manipulated using client-side code. There are no
      special requirements for using Connector/NET with BLOB
      data.
    
      Simple code examples will be presented within this section, and a
      full sample application can be found in the
      Samples directory of the Connector/NET installation.
