fetch_array() Erhaltung ORDER BY nicht aus Abfrage

dies ist mein Code:

die Tabelle wie folgt aussieht:

well_id  int(11) 

well_name varchar(50) 

last_pull datetime 

hrs_to_fill datetime 

, die durch nicht bestellt Datetime-Feld wie es sein sollte. Ausführen der Abfrage auf PHPMyadmin funktioniert gut, aber dieser Code ist nicht ... Irgendwelche Gedanken?

Danke,

Luis

Answer 1

Ihre Daten tatsächlich bestellt ist; Wenn Sie genau hinsehen, werden Sie sehen, dass es für jede Bohrung nach Datum/Uhrzeit sortiert wird. Der Grund dafür ist, dass Sie zwei Schleifen haben, die innere Schleife wird dreimal durchlaufen, eine für jede Vertiefung.

Möglicherweise müssen Sie die innere Schleife nach der äußeren Schleife verschieben, so dass Sie die temp_wells Tabelle in der ersten Schleife auffüllen und in der zweiten abfragen.
