DBIx::Class::Storage::DBI::ODBC::ACCESS - Support specific to MS Access over ODBC

Description

       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 information.

       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.

Example Dsn

         dbi:ODBC:driver={Microsoft Access Driver (*.mdb, *.accdb)};dbq=C:\Users\rkitover\Documents\access_sample.accdb

Text/Image/Memo 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.
