Php SQL：不改变where子句的含糊不清的列解析

我有以下SQL查询：

SELECT call_type FROM INCOMING_CALLS, LIVE_CALLS 

WHERE LIVE_CALLS.status='INCALL' and INCOMING_CALLS.callerid = LIVE_CALLS.callerid

AND pbl_id in ('111','190','121','111','-','111','121','303','6730','-');

表、LIVE_CALLS和INCOMING_CALLS都有pbl_id列。这显然会导致以下错误：

ERROR 1052 (23000): Column 'pbl_id' in where clause is ambiguous

我理解通过改变来解决这个问题是非常简单的

pbl_id in (

到

及

但我不能这样做，因为下面的部分是动态构建的，我无法控制它

AND pbl_id in ('111','190','121','111','-','111','121','303','6730','-');

---

我需要匹配两个表的pbl_id。有什么提示吗？如果您添加以下语句：

INCOMING_CALLS.pbl_id = LIVE_CALLS.pbl_id

然后将其中一个与in语句进行比较

AND INCOMING_CALLS.pbl_id in ('111','190','121','111','-','111','121','303','6730','-');

再想一想，你为什么不加入我们的行列呢

SELECT call_type FROM INCOMING_CALLS
LEFT JOIN LIVE_CALLS ON LIVE_CALLS.pbl_id = INCOMING_CALLS.pbl_id
WHERE LIVE_CALLS.status='INCALL' and INCOMING_CALLS.callerid = LIVE_CALLS.callerid
AND pbl_id in ('111','190','121','111','-','111','121','303','6730','-');

---

您可以使用子查询：

select call_type
from INCOMING_CALLS ic
inner join (select distinct callerid from LIVE_CALLS
            where LIVE_CALLS.status='INCALL') lc
    on ic.callerid = lc.callerid
where 1 = 1
AND pbl_id in ('111','190','121','111','-','111','121','303','6730','-');

---

请看。

动态查询部分是如何构建的？一种返回带有该字符串的变量的方法。顺便问一下，这有关系吗？和传入的呼叫。pbl_id in（'111'，'190'，'121'，'111'，'111'，'121'，'303'，'6730'，'-'）；如问题中所述，我无法预先设置传入电话tp pbl_id，因为我无法控制它。谢谢你无法控制它。。。我想知道这在代码中是如何实现的。我刚刚读了你的另一条评论，为什么不在pbl_id上使用str_替换并为表添加前缀呢？这在团队协作时在代码中是可以实现的。谢谢你的帮助。加入表格是解决方案。工作起来很有魅力！谢谢
