从同一个表中获取两个不同值的post id

Question

我有两张桌子：

tabel1
id name address
1  ss    aaaa
2  ee    wwww

tabel2
id tid key value
1  1   rr   ggg
2  1   ww   ttt
3  2   rr   ggg
4  2   ww   ttt

我想获取tabel1的值，其中“key”是（rr AND ww），值是（ggg AND ttt）。 我正在使用这个：

SELECT t1.* FROM tabel1 t1 JOIN tabel2 t2 ON  t1.id = t2.tid WHERE (t2.key = 'rr' AND t2.value ='ggg') OR (t2.key='ww' AND t2.value = 'ttt')

但我只得到这个： tabel1

  id name address
   1  ss    aaaa

Answer 1

SELECT t1.*,t2.* FROM tabel1 t1 JOIN tabel2 t2 ON  t1.id = t2.tid WHERE (t2.key = 'rr' AND t2.value ='ggg') OR (t2.key='ww' AND t2.value = 'ttt')
