第一个错误是因为在两个主SELECT语句（联合在一起）中，您有不同的列名-因此视图不知道如何称呼它们，并要求您显式命名它们，例如，每个语句中的第一列：

SELECT a.orodr# orodr_ ...
SELECT d.orodr# as ordddd ...

对于第二个错误，ORPTIM列的数据类型是什么

我猜这种类型的构造导致了这个问题：

CASE orptim
        WHEN 0
            THEN Varchar(0)
            ELSE CONCAT(CONCAT(SUBSTRING(orptim, 1, 2), ':'), SUBSTRING(orptim, 3, 4))

---

如果orptim是一个数字/小数，那么“WHEN 0”将起作用，但“SUBSTRING（orptim，1，2）”将不起作用-因为您不能将数字作为子字符串。如果orptim是一个字符串，那么“WHEN 0”w=可能会引起问题。

谢谢，我理解了有关列标题的部分。由于Orptim是一个十进制数，将char typecaset添加到代码中会解决这个问题吗？例如：CASE orptim WHEN 0然后Varchar（0）ELSE CONCAT（CONCAT（SUBSTRING（char（orptim），1，2），“：”），SUBSTRING（char（orptim），3，4））可能会工作，但前提是十进制值始终包含至少4位数字。如果没有，那么您需要格式化这些值，以便您的子字符串返回您需要的值，例如，用零填充值，非常感谢您的帮助！！因此，问题是orptim是一个长度为4的字符，它似乎包含转换为字符的数字数据类型。所以0应该是0000。再次感谢。如果没有你的帮助，我永远不会明白。
