DBIx::Class::Storage::User:ContributDBIx::Class::Storage::DBI::ODBC::ACCESS(3)NAMEDBIx::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 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.
