DBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server::CuUser(Contributed Perl DocumDBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server::Cursor(3)NAME
DBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server::Cursor - Remove trailing NULLs in binary data and normalize GUIDs for MSSQL over ADO
DESCRIPTION
This class is for removing trailing "NULL"s from binary data and removing braces from GUIDs retrieved from Microsoft SQL Server over ADO.
You probably don't want to be here, see DBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server for information on the Microsoft SQL Server
driver for ADO and DBIx::Class::Storage::DBI::MSSQL for the Microsoft SQL Server driver base class.
Unfortunately when using DBD::ADO, binary data comes back padded with trailing "NULL"s and GUIDs come back wrapped in braces, the purpose
of this class is to remove the "NULL"s and braces. DBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server sets cursor_class to this class by
default. It is overridable via your connect_info.
You can use DBIx::Class::Cursor::Cached safely with this class and not lose the binary data normalizing functionality, ::Cursor::Cached
uses the underlying class data for the inner cursor class.
