This class implements support specific to Microsoft Access over ODBC.
It is a subclass of DBIx::Class::Storage::DBI::ODBC and
DBIx::Class::Storage::DBI::ACCESS, see those classes for more
It is loaded automatically by DBIx::Class::Storage::DBI::ODBC when it
detects a MS Access back-end.
This driver implements workarounds for IMAGE and MEMO columns, and
DBIx::Class::InflateColumn::DateTime support for DATETIME columns.
Avoid using TEXT columns as they will be truncated to 255 bytes. Some other
drivers (like ADO) will automatically
convert TEXT columns to MEMO, but the ODBC driver does not.
IMAGE columns work correctly, but the statements for inserting or updating an
IMAGE column will not be cached, due to a bug in the
Access ODBC driver.
MEMO columns work correctly as well, but you must take care to set
LongReadLen to $max_memo_size * 2 + 1. This is done for
you automatically if you pass LongReadLen in your
connect_info; but if you set this
attribute directly on the $dbh, keep this limitation in mind.
