如何加入3表而不重复id？

Question

我有3个表：te_event，te_venue，te_category。

te_event表包含列：categoryID, venueID, event description, title, date, price.

te_venue表包含列：venueID, venueName and location.

te_category包含列：catID and catDesc.

这是我的查询

SELECT *
FROM   te_events
INNER JOIN te_venue
        ON te_events.venueid = te_venue.venueid
INNER JOIN te_category
        ON te_events.catid = te_category.catid  

但它通过重新编写ID

来显示

eventID | eventTitle | eventDescription |venueID | catID| eventStartDate |eventEndDate |eventPrice | venueID | venueName | location| catID | catDesc

Answer 1

SELECT e.event_description, e.title,e.date,e.price,v.venueName,v.location,c.catDesc
     FROM te_events e 
     INNER JOIN te_venue v ON e.venueID  = v.venueID 
     INNER JOIN te_category c ON e.catID = c.catID

请参阅下面的结果

Answer 2

  

为什么不选择您需要的列？例如：

     SELECT  E.eventID, E.eventTitle, E.eventDescription,
             E.eventStartDate, E.eventEndDate, E.eventPrice
             E.catID, V.venueID, V.venueName, V.location
             FROM te_events AS E
             INNER JOIN te_venue AS V ON E.venueID = V.venueID 
             INNER JOIN te_category AS C ON E.catID = C.catID

它可能会长一点，但它可能仍然很可能会给你你期望的结果。

干杯＆amp;好运。

Answer 3

SELECT DISTINCT t1.categoryID,t1.venueID,t1.eventDescription,t1.title,t1.date,t1.price,t2.venueName, t2.location, t3.catDesc FROM te_events AS t1
                 INNER JOIN te_venue AS t2 ON te_events.venueID = te_venue.venueID 
                 INNER JOIN te_category AS t3 ON te_events.catID = te_category.catID
