I am trying to call the mysql stored procedure from the php code given below

query($sql1);

while ($data1 = $query1->fetch_row())
{
echo $data1[0].”\n”;
$sql2 = “call getCapitals(\”".$data1[0].”\”)”;Deutschland

//SQL which does the same thing:
//$sql2 = “select concat(country, \”, capital: \”, capital) from countries where country like ‘”.$data1[0].”‘”;

$query2 = $mysqli->query($sql2);

while ($data2 = $query2->fetch_row())
{
echo $data2[0].”\n”;
}
$query2->free(); // unsuccessful attempt to clear the results and get the next SP going
}
?>

Once i Execute the code i am getting the following result

Result:

Deutschland

Fatal error: Call to a member function fetch_row() on a non-object in C:\wamp\www\SMS\Smart\Test\Test.php on line 27

I think the problem is that the stored procedure calling is occurring only once.

Could you please help me to solve this problem?

Thanks in advance
