如何聯接兩個表

Question

我有兩個表，分別是EventTable和VenueTable

我將彼此的prinamrykey用作外鍵。 表結構如下;

EventID|VenueID|EventName 
    1  |    1  | Event1 
    2  |    1  | Event2 
    3  |    2  | Event3 


VenueId|EnevtID|VenueNAme
   1   |   1   | Venue1 
   2   |   2   | Venue2 

我想要的結果如下;

VenueID | VenueName | EventID | EventName
   1    | Venue1    |  1      | Event1 
   1    | Venue1    |  2      | Event2 
   2    | Venue2    |  2      | Event2
   2    | Venue2    |  3      | Event3

我已使用內部聯接執行此操作。但是無法獲得預期的結果。

這個怎么做 ？

謝謝..

Answer 1

嘗試這個：

SELECT
    v.VenueID,
    v.VenueName,
    v.EventID,
    e.EventName
FROM
    VenueTable v
INNER JOIN
    EventTable e 
    ON (v.EventId = e.EventId)

UNION

SELECT
    v.VenueID,
    v.VenueName,
    v.EventID,
    e.EventName
FROM
    VenueTable v
INNER JOIN
    EventTable e 
    ON (v.VenueID = e.VenueID)

這模擬了MySQL中的FULL OUTER JOIN

Answer 2

這應該可以解決問題：

 select VenueID, VenueName, EventID, EventName
    from EventTable, VenueTable
    where EventTable.VenueID = VenueTable.VenueID

記住mysql的分隔符

Answer 3

SELECT v.VenueID, v.VenueName, v.EventID, e.EventName
FROM VenueTable v
INNER JOIN EventTable e  ON (v.EventId = e.EventId)

甚至

SELECT v.VenueID, v.VenueName, v.EventID, e.EventName
FROM VenueTable v, EventTable e 
WHERE v.EventId = e.EventId
