Question

我遇到了正确过滤表格F0005的问题。我尝试过很多种不同的查询方法。我想要完成的是在加入之前对F0005进行过滤。

这就是我希望它被过滤的结果，结果在那张桌子上是完美的。

SELECT LTRIM(F0005.DRKY), F0005.DRDL01, F0005.DRRT, F0005.DRSY
    FROM
            SENCOM.F0005 F0005
            WHERE LTRIM(F0005.DRKY) != '' AND F0005.DRRT IN ('W1','08') AND F0005.DRSY NOT IN ('30','32','98')

这是我的整个查询以及我在加入表之前过滤表的尝试。

  ON
    ABAC15 = F0005Filtered.DRKY

当我尝试这个时，我得到列错误，SQL0205]列DRKY不在* N中的表F0005FILTERED中。

感谢您的帮助，我对此有点新鲜，并且没有想法！：）

非常感谢大家，我的问题是我的嵌套选择的格式化，但也有一些完全不同的东西。我加入了错误的字段，所以没有匹配，这就是为什么我得到了NULL！再次感谢!!

这是最终版本。我愿意接受一些优化建议。否则很高兴它完成了！

Answer 1

如果在函数中包装字段，则需要在之后命名。

将LTRIM(F0005.DRKY),更改为LTRIM(F0005.DRKY) AS DRKY,

Answer 2

在嵌套查询中，您缺少DRKY的别名：

SELECT
            LTRIM(F0005.DRKY) as DRKY,
            F0005.DRDL01,
            F0005.DRRT,
            F0005.DRSY
            FROM SENCOM.F0005 F0005
        WHERE LTRIM(F0005.DRKY) != ''
        AND F0005.DRRT IN ('W1',
                           '08')
        AND F0005.DRSY NOT IN ('30',
                               '32',
                               '98')) F0005Filtered

如果在没有返回LTRIM(F0005.DRKY)

的列名时没有别名

Answer 3

您需要在过滤后的表格中命名计算列。

SELECT LTRIM(F0005.DRKY) AS DRKY, F0005.DRDL01, F0005.DRRT, F0005.DRSY
FROM SENCOM.F0005 F0005
WHERE LTRIM(F0005.DRKY) != '' 
   AND F0005.DRRT IN ('W1','08') 
   AND F0005.DRSY NOT IN ('30','32','98')

请注意AS DRKY

Answer 4

你真的需要重新格式化你的问题，但我相信我知道你哪里出错了。

您的表别名F0005Filtered不是JDE用户定义代码表的别名。您已经创建了一个子选择，这是F0005Filtered实际代表的。

此外，在该子选择内，您没有名为DRKY的列。

您正在该字段上使用TRIM功能而未指定列名。

要修复，只需重新创建别名： -

LTRIM(F0005.DRKY) AS DRKY

修改

回应用户提问。

为什么不将IN语句作为JOIN条件的一部分？

LEFT OUTER JOIN SENCOM.F0005 UDC ON LTRIM(UDC.DRKY) != '' AND ABAC15 = TRIM(UDC.DRKY) AND UDC.DRRT IN ('W1','08') AND UDC.DRSY NOT IN ('30', '32','98')

用户定义的代码表往往不会那么大。我为一家大型跨国公司做了一些工作，我们的工作量大约为70K。

LEFT JOIN上的嵌套Select语句
