mySQL Fehlermeldung

[black79]

hallo, hier mein SQL Code in PHP

Code:

$result = $link->query("SELECT COUNT(*) AS id FROM TelegramStorage
                          JOIN TelegramDescription WHERE LEFT (TelegramDescription.bosmon = 1)");
  $TelegramStorage_Count = $result->fetch_all(MYSQLI_ASSOC);
  $total = $TelegramStorage_Count[0]['id']

sobald ich die zweite Tabelle mit der Bedingung ( JOIN TelegramDescription WHERE LEFT ...) eingebe kommt es zur Fehlermeldung!

Fatal error: Uncaught Error: Call to a member function fetch_all() on bool in /volume1/web/oesoft/monitorOESoft.php on line 7 Error: Call to a member function fetch_all() on bool in /volume1/web/oesoft/monitorOESoft.php on line 7 Call Stack: 0.0006 361416 1. {main}() /volume1/web/oesoft/monitorOESoft.php:0
