DBIx::Class::Storage::DBI::ODBC::ACCESS \- Support specific to MS Access over ODBC
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class implements support specific to Microsoft Access over \s-1ODBC.\s0
.PP
It is a subclass of DBIx::Class::Storage::DBI::ODBC and
DBIx::Class::Storage::DBI::ACCESS, see those classes for more
information.
.PP
It is loaded automatically by DBIx::Class::Storage::DBI::ODBC when it
detects a \s-1MS\s0 Access back-end.
.PP
This driver implements workarounds for \f(CW\*(C`IMAGE\*(C'\fR and \f(CW\*(C`MEMO\*(C'\fR columns, and
DBIx::Class::InflateColumn::DateTime support for \f(CW\*(C`DATETIME\*(C'\fR columns.

.SH "TEXT/IMAGE/MEMO COLUMNS"
.IX Header "TEXT/IMAGE/MEMO COLUMNS"
Avoid using \f(CW\*(C`TEXT\*(C'\fR columns as they will be truncated to 255 bytes. Some other
drivers (like \s-1ADO\s0) will automatically
convert \f(CW\*(C`TEXT\*(C'\fR columns to \f(CW\*(C`MEMO\*(C'\fR, but the \s-1ODBC\s0 driver does not.
.PP
\&\f(CW\*(C`IMAGE\*(C'\fR columns work correctly, but the statements for inserting or updating an
\&\f(CW\*(C`IMAGE\*(C'\fR column will not be cached, due to a bug in the
Access \s-1ODBC\s0 driver.
.PP
\&\f(CW\*(C`MEMO\*(C'\fR columns work correctly as well, but you must take care to set
LongReadLen to \f(CW\*(C`$max_memo_size * 2 + 1\*(C'\fR. This is done for
you automatically if you pass LongReadLen in your
connect_info; but if you set this
attribute directly on the \f(CW$dbh\fR, keep this limitation in mind.
