DBIx::Class::Storage::DBI::ODBC::ACCESS(3)

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

WARNING
I am not a DBI, DBIx::Class or MS Access guru. Use this module with that in mind.

This module is currently considered alpha software and can change without notice.

DESCRIPTION
This class implements support specific to Microsoft Access over ODBC.

It is loaded automatically by by DBIx::Class::Storage::DBI::ODBC when it detects a MS Access back-end.

SUPPORTED VERSIONS
This module have currently only been tested on MS Access 2003 using the Jet 4.0 engine.

As far as my knowledge it should work on MS Access 2000 or later, but that have not been tested. Information about support for different version of MS Access is welcome.

IMPLEMENTATION NOTES
MS Access supports the @@IDENTITY function for retrieving the id of the latest inserted row. @@IDENTITY is global to the connection, so to support the possibility of getting the last inserted id for different tables, the insert() function stores the inserted id on a per table basis. last_insert_id() then just returns the stored value.

KNOWN ACCESS PROBLEMS

Invalid precision value
    This error message is received when trying to store more than 255 characters in a MEMO field. The problem is (to my knowledge) an error in the MS Access ODBC driver. The problem is fixed by setting the "data_type" of the column to "SQL_LONGVARCHAR" in "add_columns". "SQL_LONGVARCHAR" is a constant in the "DBI" module.

IMPLEMENTED FUNCTIONS

  bind_attribute_by_data_type
This function currently supports the SQL_LONGVARCHAR column type.

  insert

  last_insert_id

  sqlt_type

BUGS
Most likely. Bug reports are welcome.
