We are using a simple perl script to connect to teiid and run a query, spitting out the results. Unfortunately we find that the perl client hangs forever when trying to execture/return a resultset > 512 rows, but 512 or less it runs fine
The code for a test script is as follows
#! /usr/bin/perl use strict; use warnings; use DBI; my $db_type = 'Pg'; my $db_name = 'EngVDBF'; my $db_host = 'vdb.engineering.redhat.com'; my $db_port = 35432; my $user = 'teiid'; my $pass = 'teiid'; my $attr = { AutoCommit => 0, RaiseError => 1 }; my $dsn = sprintf( "dbi:%s:dbname=%s;host=%s;port=%s", $db_type, $db_name, $db_host, $db_port ); my $dbh = DBI->connect( $dsn, $user, $pass, $attr ); my $limit = ( $ARGV[0] ) ? "limit $ARGV[0]" : ""; my $query = <<QUERY; select bugs.bug_id, bugs.priority, bugs.bug_severity from BugzillaS.bugs bugs $limit QUERY my $sth = $dbh->prepare($query); $sth->execute(); while ( my @row = $sth->fetchrow_array() ) { print join( ',', map {"\"$_\""} @row ) . "\n"; } $sth->finish(); $dbh->disconnect();
When running
./teiid.pl 512
Query runs fine, when we run
./teiid.pl 513
Client just sits there forever (the query actually has about 1800 odd rows returning).
