SQL错误[42972]：[SQL0338]JOIN谓词或MERGE ON子句无效

我试图运行下面的查询，但表DB170P中的联接中出现错误。你能帮我吗

SELECT ACBAC AS "CBUYER"

DB170PDB170P中的左外连接SELECT*语法非常奇怪。。。 左外接DP170P是您真正需要的

在连接到DB170P的过程中，尝试转换为日期数据类型时可能会出现错误

您是否在作业日志中查看了其他错误信息

我建议

从嵌套表表达式NTE移动到通用表表达式CTE 构建一个用户定义的函数UDF来处理日期转换或下载开源 在CTEs中通过自定义项进行日期转换 使用显式联接 通常最好不要使用SELECT*，即使您确实需要所有列 以下是一个CTE版本开始时的样子

with AAAA as (SELECT trim(IHPLST) as lastInvNbr
             FROM IC090P 
             UNION 
             SELECT trim(IHPLST) 
             FROM IC090B)
 , X as (SELECT trim(PIIVNO) as InvNbr 
         FROM PC090P 
         join PC100P 
           on PIBLNO=PHBLNO
         )
select * 
from aaaa join X on aaaa.lastInvNbr = x.InvNo

---

除了可重用之外，CTE还可以很容易地从mycte中删除SELECT*，以便在构建语句时可以看到中间结果。

错误消息是针对DB2的，因此MySQL标记不合适。显式连接链在隐式、逗号分隔的连接之前进行计算。范围问题？最好的编程实践是限定所有列，至少当涉及多个表时。HCRCD属于哪个表？它属于IC010P表。
