It's quite weird, but maybe someone has already encountered the same problem.
The code, a service callback, is quite simple:
function myservice_service_search_products($query) {
$sql = "SELECT * FROM mv_products WHERE description LIKE '%". mysql_real_escape_string($query) ."%'";
$result = db_query($sql);
$products= array();
while ($product = db_fetch_object($result)) {
$products[] = $product;
}
return $products;
}When I call it first time with a parameter (let's say "red"), it returns correctly the set of data. On subsequent calls with different parameters ("black", "blue" or whatever) it returns an empty dataset. If I call again with the first parameter ("red") I receive back again the correct dataset.
I checked this on two different systems (one Mac and one Linux, with different PHP/Mysql combination) with same results. So the error is sure mine, but I can't find it...
It seems like a handle has not been released and any call to that table works on the first dataset only...
Or maybe it's not possible to use db_query within a web service?
Other hint: of course querying the database directly with the SQL produces always the correct dataset.
Any help is appreciated...
