Hey,
I'm using a PDO-MySQL in a class of my Accounting-Framework. The problem: if
I call my function query(), see below, multiple times, I get the error:
Array ( [0] => HY000 [1] => 2014 [2] => Cannot execute queries while other
unbuffered queries are active. Consider using PDOStatement::fetchAll().
Alternatively, if your code is only ever going to run against mysql, you may
enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY
attribute. ) 1
protected function query($query) {
try {
if (preg_match("@^select@is", $query)) {
$sth = $this->link->prepare($query) or
die(print_r($this->link->errorInfo()));
$sth->execute();
// Get RowCount
$rc = 0;
while($count = $sth->fetch(PDO::FETCH_ASSOC)) $rc++;
$this->count[(string)$sth] = $rc;
$sth->execute();
return $sth;
} else {
$this->link->query($query);
return true;
}
} catch (Exception $e) {
$dbh->rollBack();
echo "DATABASE OPERATION FAILED: " . $e->getMessage();
exit;
}
}
The Solution described in the official manual is:
$db->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY, true);
My Connection function (which also includes the solution):
private function connect() {
$this->link = new
PDO('mysql:host=localhost;dbname=micronax_mymicronax', "mymicronax",
"l{7kD01eG-B[");
$this->link->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY, true);
return true;
}
$link is defined as: protected $link = false;
But I still get the damn error-message. What's going wrong here?
Other possibilities, ex. Adding the MYSQL_ATTR_USE_BUFFERED_QUERY to "new
PDO()" or adding it to "prepare($query)" doesn't show affect.
Please help me,
Greetings from Germany and happy easter,
