it fixes the issue First, let me blame your intention.
"To do something in one line" (implying "using some syntax tricks") is not the way to go.

getting "mysqli num_rows Commands out of sync; you can't run this command now" error in mysql query

getting "mysqli num_rows Commands out of sync; you can't run this command now" error in mysql query

hope this fix your issue I'm having a problem with the a mysqli query I'm calling from a php script. I've rewritten it many times and keep getting the error: "mysqli num_rows Commands out of sync; you can't run this command now" This is the first attempt to access the database from this page. I was previously binding the parameters and then calling: $checkAcct->num_rows() and getting the same problem. I also tried what someone suggested in a different post on this site: do { $checkAcct->use_result(); } while( $checkAcct->next_result() ); but this didn't work either and I got the same error. After I make sure a user with these details isn't in the db I execute another query to insert the user's info into the site but the error message I get pertains to this query here. Let me know if it would help to see the other query also. , Can you change the above code like this and see what you are getting
code :
$checkAcct = $dbConn->stmt_init();
$existingAcct = array();

if ($checkAcct->prepare("select usrName, eAddy from usr where usrName = ? OR eAddy = ?"))
{
    $checkAcct->bind_param("ss", $usr, $eml);
    $checkAcct->execute();
    $checkAcct->store_result();
    printf("Number of rows: %d.\n", $stmt->num_rows);
    $checkAcct->free_result();
    $checkAcct->close();
}

Does that help Since you are working with a resource it has a pointer. Once you get to the end you can't use it anymore. I think you can reset it but why not mix the new with the old?
I don't think you're going to have too much overhead, any that matters anyway, to do something like this:
code :
$settings = array();
$query = $mysqli->query("SELECT * FROM `settings`");
while ($current_setting = $query->fetch_object()) {
     $settings[$current_setting->setting] = $current_setting->value;
}
$settings = new stdClass();
$query = $mysqli->query("SELECT * FROM `settings`");
while ($current_setting = $query->fetch_object()) {
     $settings->{$current_setting->setting} = $current_setting->value;
}

should help you out title is implemented like the staticmethod descriptor, so it will work on both the str class and any of it's instance. But when it's called from str class, it needs one addition parameter -- the string to operate on.
In your case, you've made first_method an unbound function that can only be called as a class attribute. It can't be called from instance, as once you do instance.first_method() Python implicitly pass the instance (self in the usual term) as the first argument at runtime, but the function does not take any argument hence the error.
code :
class NewList():
    @staticmethod
    def first_method(cls):
        print("hello")

Does that help I would like to know if it is possible to do a query in which two different tables will be checked and as a result the number of rows will return or even true/false. , Try below:

With these it helps At any time your queryDict has only one element; the only time that GetQuery() doesn't log an error message and doesn't return null is when you pass 1 to it. as a consequence Read(1) returns a list of all Drivers, otherwise throws a NullReferenceException because, well, query is null.
You should use something like this:
