 [2005-04-29 02:45 UTC] sales at girderboot dot com
Description:
------------
After executing a query using a stored procedure that returns a result set, no futher queries can be executed.

SProc's that don't return a result set, or embedded SQL queries are not affected (but even they still cannot run after a SP with a result set is run.)

MySQL and PHP both version 5.0.4

Reproduce code:
---------------
$db = new mysqli('localhost','xxx','xxx','campnet');
	
if (!$exec = $db->query("CALL Acct_Bal(1)"))
		echo $db->error;
	$balance = $exec->fetch_row();
	
	$exec->close();
	
	echo $balance[0];
	echo "<BR>";
// Second Time
	if (!$exec = $db->query("CALL Acct_Bal(1)"))
		echo $db->error;
	$balance = $exec->fetch_row();
	
	$exec->close();
	
		echo $balance[0];

Expected result:
----------------
Should Output the same result Twice (In this case, the accout balance):


0.00
0.00

Actual result:
--------------
0.00
Lost connection to MySQL server during query
Fatal error: Call to a member function fetch_row() on a non-object in C:\Program Files\Apache Group\Apache2\htdocs\driver.php on line 40

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Stored procedures can return more than one resultset, e.g. 
 
CREATE PROCEDURE foo() 
BEGIN 
  SELECT 'foo' FROM DUAL; 
  SELECT 'bar' FROM DUAL; 
END 
 
therefore you should handle resultsets like in 
mysqli_multi_query (calling mysqli_next_result to clear 
remaining data on socket).
