Sie machen im Grunde eine Vereinigung von LEFT und RIGHT JOIN.
Sie haben tatsächlich eine interessante Falte, da Sie auch die Zeilen auf 3 begrenzen möchten. Um dies zu lösen, müssen Sie
- Limitiere sowohl die "linke" als auch die "rechte" Auswahl um 3
- Verwenden Sie dann das Ergebnis der UNION in einer Inline-Ansicht
- begrenzen Sie dann die Vereinigung wieder auf 3
AKTUALISIEREN Wenn ich mich nicht irre, können Sie dies leider nicht direkt in einer UNION tun, also müssen Sie vor der UNION eine weitere Ebene von Inline-Ansichten hinzufügen
Die LIMITS innerhalb der UNION bieten einige Leistungsvorteile und die Grenze danach liefert Ihnen die richtigen Ergebnisse.

AKTUALISIEREN Unter Verwendung der Vorschläge von spencer7593 und ypercube ist hier ein alternativer Ansatz mit zwei UNION ALL-Anweisungen und ohne Inline-Ansichten.
