Subject: check DBD::ODBC version when disabling array ops
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=11f7049f71cd5d6b891e8addd3c0d9cd2a27c3e8;p=dbsrgits%2FDBIx-Class-Historic.git

check DBD::ODBC version when disabling array ops

After 1.35 DBD::ODBC will disable array operations for execute_for_fetch
by default, and the $dbh attribute is changing from
'odbc_disable_array_operations' to 'odbc_array_operations', but we still
set the new attribute to 0 just in case.

Put the version checks and the setting of the appropriate attribute in
_disable_odbc_array_ops in ODBC.pm, and call it from the 3 drivers where
we currently need to disable them.
