I may have discovered an issue with the postgres ODBC Driver.
Postgres ODBC Driver version:
perl -MDBI -le 'my $h = DBI->connect; print $h->get_info(7);'
09.00.0310
Platform: Linux, Ubuntu
I maintain Perl DBD::ODBC and the test suite shows a problem because when calling SQLGetTypeInfo some types return
'CREATE_PARAMS' => 'max. length'
but then the COLUMN_SIZE is missing. e.g.:
$VAR1 = {
'UNSIGNED_ATTRIBUTE' => undef,
'MAXIMUM_SCALE' => undef,
'INTERVAL_PRECISION' => '0',
'CREATE_PARAMS' => 'max. length',
'NUM_PREC_RADIX' => undef,
'PRECISION' => 255,
'SEARCHABLE' => '3',
'MONEY' => '0',
'AUTO_INCREMENT' => undef,
'LOCAL_TYPE_NAME' => undef,
'LITERAL_PREFIX' => '\'',
'MINIMUM_SCALE' => undef,
'TYPE_NAME' => 'varchar',
'NULLABLE' => '1',
'DATA_TYPE' => 12,
'SQL_DATA_TYPE' => '12',
'LITERAL_SUFFIX' => '\'',
'CASE_SENSITIVE' => '1',
'SQL_DATETIME_SUB' => undef
};
See http://msdn.microsoft.com/en-us/library/ms714632%28v=vs.85%29.aspx where COLUMN_SIZE was introduced in ODBC 2
(decadesago) and should exist in the columns returned. Without it, the application cannot know what to put in varchar
(size_here)after a column in a create table.
I've put in a special case for now to work around this problem but it issues a warning too. If you need anything
furtherfrom me please let me know.
