=head1 NAME

DBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server::Cursor - Remove trailing
NULLs in binary data and normalize GUIDs for MSSQL over ADO

=head1 DESCRIPTION

This class is for removing trailing Cs from binary data and removing braces
from GUIDs retrieved from Microsoft SQL Server over ADO.

You probably don't want to be here, see
L for information on the
Microsoft SQL Server driver for ADO and L for
the Microsoft SQL Server driver base class.

Unfortunately when using L, binary data comes back padded with
trailing Cs and GUIDs come back wrapped in braces, the purpose of this
class is to remove the Cs and braces.
L sets
L to this class by
default. It is overridable via your
L.

You can use L safely with this class and not lose
the binary data normalizing functionality,
L<::Cursor::Cached|DBIx::Class::Cursor::Cached> uses the underlying class data
for the inner cursor class.
