"""
         .description

             This read-only attribute is a sequence of 7-item
             sequences.  Each of these sequences contains information
             describing one result column: (name, type_code,
             display_size, internal_size, precision, scale,
             null_ok). The first two items (name and type_code) are
             mandatory, the other five are optional and must be set to
             None if meaningfull values are not provided.
