The pull request attached to this bug report will introduce another error when
the another statement is issued without fetching ALL the previous results:
SQLSTATE[HY000]: General error: 20019 Attempt to initiate a new Adaptive Server
operation with results pending [20019] (severity 7) [select 1+1 as result1]
The last statement should be able to be flushed using dbcancel(), but for some
reason this is not working as documented. I also tried dbcanquery(). Both
render
the statement not re-useable, but weirdly enough the column metatdata is
repopulated with the new column names and types
code: print_r($pdo->getColumnMeta(0))

Sorry, I commented without properly testing, just compiled 5.4.15 and tested
with $statement = null; and it was possible to keep using the connection, even
with transactions.
Also works with unset($statement);
Test script:
---------------
$db->exec('create table #test ( id int not null )');
$db->exec('begin transaction test1');
$db->exec('insert into #test (id) values (100)');
$db->exec('insert into #test (id) values (200)');
$db->exec('insert into #test (id) values (300)');
$db->exec('commit transaction test1');
$stmt = $db->query('select * from #test');
var_dump($stmt->fetchAll(PDO::FETCH_NUM));
$stmt->closeCursor();
unset($stmt);
$db->exec('drop table #test');
Expected result:
----------------
array(3) {
[0]=>
array(1) {
[0]=>
string(3) "100"
}
[1]=>
array(1) {
[0]=>
string(3) "200"
}
[2]=>
array(1) {
[0]=>
string(3) "300"
}
}

using $statement = null; would make it impossible to use transactions and some
stored procedures.
This was introduced back in late
2011(https://github.com/php/php-src/commit/3a069e814fe01b36812b5c768dd52ccdea3ed098)
but only on PHP 5.4+ (5.3- worked as expected).
I compiled PHP 5.4.13 with the pull request applied and it worked as expected.
