MySQL使用AND组合两个SELECT语句

Question

我已经尝试将这两个陈述合并两周，但无济于事。我尝试过使用UNION，但它会生成＆＃34;列数不同＆＃34;错误。现在我希望使用AND子句来组合这些语句。在此先感谢：）

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

这是你正在尝试做的事情吗？：

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
