我有以下查询，它获取每个月从三个不同表中获取数据的总数：

--DROP TABLE [database].[dbo].[finaltable]

我在这里用虚拟表格问我原来的问题：Stackoverflow Question Link

很多人帮助我使用虚拟桌子。现在我试图用我真实的表做同样的事情，但它给了我上面列出的所有错误。

如何解决错误，所以它就像使用虚拟表一样工作？

问题出在这一部分：

SELECT [Date], [APSURGICALTOTAL], [APDERMTOTAL], [GYNNONGYNTOTAL], [CYTOHPV], [INHOUSE], [HEMOTOLOGY], [CHEMISTRY], [BLOODBANK], [REFLAB], [URINALYSIS], [SEROLOGY], [MICROBIOLOGY]
    FROM [database].[dbo].[weeklytable]
    UNION ALL
    SELECT CONVERT(VARCHAR(10), [Date], 101), [LastWeekEMROrders], [LastWeekAccLabOrders], [LastWeekLabResults], NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL
    FROM [database].[dbo].[dailytable]
    UNION ALL
    SELECT CONVERT(VARCHAR(10), [Date], 101), [RAD EMR ORDERS], [EMR ORDERS], [ACCESSIONED LAB ORDERS], [RAD RESULTED], [LAB_RESULT], [RAD ACCESSIONED], [PENDING FOR PROCESSING], NULL, NULL, NULL, NULL, NULL
    FROM [database].[dbo].[othertable]

问题列未显示在原始选择中。当您使用UNION ALL时，第一个选择的列应与以下查询匹配。

您需要确保UNION ALL语句中的列“排队”。更容易看出是否将列名放在所有列中 - 如下所示：

您需要确保日期列是日期或日期时间类型。如果您存储字符串然后转换它们 - 尝试对字符串进行日期比较是一个糟糕的计划 - 使用日期并让服务器将苹果与苹果进行比较。
