select - 如何从多个表中使用 LIKE 加入 IN SELECT？

Question

我正在尝试创建一个查询来搜索所有共享类似属性的记录，如下所示:

select * from table_A 
where fullname like in (select firstname from employees where X)

唯一的问题是这只是我的伪代码，我实际上正在对许多表进行排序，因此我目前的真实查询看起来像:

select * from devices 
where devicename like in (select X from X1 where T in (select T from T1 where Y in     (select Y from Y1 where Z in (select Z from Z1 where AreaName = '74';

我正在尝试使用 join 命令，但对如何将其应用于这种情况感到非常困惑。

Answer 1

尝试:

SELECT d.*
  FROM devices d
 INNER JOIN X1 ON d.devicename like '%'||x1.X||'%'
 INNER JOIN T1 ON x1.T = T1.T
 INNER JOIN Y1 ON T1.Y = Y1.Y
 INNER JOIN Z1 ON Y1.Z = Z1.Z
 WHERE Z1.AreaName = '74'
