MySQL結合了兩個SELECT語句，使用AND

Question

我一直試圖將這兩個聲明合併兩個星期，但無濟於事。我試過使用UNION，但它產生「列數不同」的錯誤。現在我希望使用AND子句來組合這些語句。感謝提前:)

SELECT te_events.eventTitle, 
     te_category.catDesc 
FROM te_events 
JOIN te_category ON te_events.catID=te_category.catID 
ORDER BY te_events.eventTitle 

SELECT eventStartDate, 
     eventEndDate, 
     eventPrice, 
     eventDescription 
FROM te_events 

Answer 1

SELECT e.eventStartDate, 
     e.eventEndDate, 
     e.eventPrice, 
     e.eventDescriptio, 
     e.eventTitle, 
     c.catDesc 
FROM te_events AS e 
LEFT JOIN te_category AS c ON e.catID=c.catID 
ORDER BY e.eventTitle 

Answer 2

這是你想要做的？：

SELECT te_events.eventTitle, 
     te_events.eventStartDate, 
     te_events.eventEndDate, 
     te_events.eventPrice, 
     te_events.eventDescription, 
     te_category.catDesc 
FROM te_events 
JOIN te_category ON te_events.catID=te_category.catID 
ORDER BY te_events.eventTitle
