Ich muss ALLE mehrere Tabellen UNION. Ich erstelle eine Abfrage über PHP und läuft erfolgreich ohne UNION ALL-Tabellen. Aber wenn ich ALLE 2 Tabellen VERBINDE, scheint es, dass die Abfrage nie auf der PHP-Seite endet, auch ich habe in pgAdmin mit dem gleichen Ergebnis getestet. Ich habe als Ergebnis eine CSV-Datei über die Shell generiert, um die Daten zu erhalten, die ich auswählen wollte, aber die Abfrage endet auch nie. Ich werde Ihre Kommentare zu schätzen wissen. Danke im Voraus.

Dies ist die Abfrage, die ALLE mehrere Tabellen UNION. Die Anzahl der Tabellen, die UNION ALL sein können, hängt von einem DateRangePicker ab. Es gibt also eine Tabelle pro Tag, zum Beispiel: F_UCell_1_170123, F_UCell_1_170124, F_UCell_1_170125, F_UCell_1_170126, etc...
