Description:
------------
As expected, after an SQLite3Result has been fully processed,
SQLite3Result::columnType() returns FALSE. If the result is
reset by calling SQLite3Result::reset(), ::columnType() yields
the expected results again; however, if the statement is reset by
calling SQLite3Stmt::reset(), ::columnType() keeps returning
FALSE.
In other words, whenever SQLite3Result::fetchArray() succeeds
(i.e. does not return FALSE), I expect SQLite3Result::columType()
to succeed (i.e. not to return FALSE). However, that does not
necessarily happen after calling SQLite3Stmt::reset().
Test script:
---------------
<?php
$db = new SQLite3(':memory:');
$db->exec("CREATE TABLE foo (bar INT)");
$db->exec("INSERT INTO foo VALUES (1)");
$stmt = $db->prepare("SELECT * FROM foo");
$res = $stmt->execute();
var_dump($res->fetchArray() !== false);
var_dump($res->columnType(0));
var_dump($res->fetchArray() !== false);
var_dump($res->columnType(0));
$stmt->reset();
var_dump($res->fetchArray() !== false);
var_dump($res->columnType(0));
$res->reset();
var_dump($res->fetchArray() !== false);
var_dump($res->columnType(0));
?>
Expected result:
----------------
bool(true)
int(1)
bool(false)
bool(false)
bool(true)
int(1)
bool(true)
int(1)
Actual result:
--------------
bool(true)
int(1)
bool(false)
bool(false)
bool(true)
bool(false)
bool(true)
int(1)
