User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_1) AppleWebKit/534.48.3 (KHTML, like Gecko) Version/5.1 Safari/534.48.3
Build Identifier:

When requesting database tables information through a database handle:

$dbh->table_info('', '%', '%)

The DBD::monetdb::db::monetdb_table_info subroutine issues an incorrect query to list schemas and tables (resulting in an error an no results)

I found the query to be:

==========
select cast( null as varchar( 128 ) ) as table_cat
, s."name" as table_schem
, t."name" as table_name
, case
when t."istable" = true and t."system" = false and t."temporary" = 0 then cast('TABLE' as varchar( 254 ) )
when t."istable" = true and t."system" = true and t."temporary" = 0 then cast('SYSTEM TABLE' as varchar( 254 ) )
when t."istable" = true and t."system" = false and t."temporary" = 1 then cast('LOCAL TEMPORARY' as varchar( 254 ) )
when t."istable" = false then cast('VIEW' as varchar( 254 ) )
else cast('INTERNAL TABLE TYPE' as varchar( 254 ) )
end as table_type
, cast( null as varchar( 254 ) ) as remarks
from sys."schemas" s
, sys."tables" t
where t."schema_id" = s."id"

This query fails because there's no (more) column "istable" in "sys.tables".

Reproducible: Always

Steps to Reproduce:

The following snippet will reproduce the error:

===========
!/usr/bin/env perl

use strict;
use warnings;

$|++;

use DBI();

my $dbh = DBI->connect('dbi:monetdb:database=testdb', 'monetdb', 'monetdb');

my $sth = $dbh->table_info('', '%', '%');

Actual Results:

DBD::monetdb::db table_info failed: SELECT: no such column 't.istable' at /opt/local/lib/perl5/vendor_perl/5.12.3/darwin-thread-multi-2level/MonetDB/CLI/MapiPP.pm line 120

Expected Results:

Table and schemas information as per DBI specs.
