Php: I want tot call the procedure and store the 4 returned objects into 4variables
if ($res = $mysqli->query( 'CALL getCdpc(1321,@co,@di,@pr,@ci);SELECT @co,@di,@pr,@ci'))<br>
{<br>
while($row = $res->fetch_object())<br>
{<br>
print($row);<br>
}<br>
$res->close();<br>
}<br>
else<br>
{<br>
print "<br> no result given <br>";<br>
}<br>
<br>
Result:<br>
-------<br>
I always get zero rows back
<br>
<br>
More info:<br>
----------<br>
in mysql sql the results get returned when I do:<br>
->call xoffercommon.getCdpc(1321,@co,@di,@pr,@ci);<br>
->select @co,@di,@pr,@ci;<br>
=> @co @di @pr @ci<br>
1 2 3 4<br>
<br>
Question:<br>
---------<br>
Do I have to run 2 queries, a call to the procedure and a select on that result?
Is there a way to run it in one line?
... please help I've nowhere found a solution to my problem, already tried return in the procedure, but this is only allowed in functions. already 2weeks gone... learned a lot by reading/trial and error ;-), but nothing cracked this case....
Not sure why you want to be passing out 4 variables when you could simply return a resultset. This would also avoid you having to change the sproc interface everytime you want to extend the data you output.

It would also be worth your while cleaning up your schema so you have more appropriate integer datatypes for your keys (not everything is a signed integer 4 bytes) and avoid the mix of fieldnames you seem to have chosen for the same thing ie Id, ID, City_Id, City_ID etc. which will avoid all that unnecessary aliasing !

Hope this helps :)
use multi_query function
$mysqli->multi_query($query)
look on example
PHP + MySql + Stored Procedures, how do I get access an "out" value?
