使用SqlServer进行硬查询（使用When和else）

时间：2018-02-20 10:12:03

标签： sql-server

我有一个查询，但我不知道为什么它是坏的。 错误是：SQL（4104）：无效的列名'CUSTOMDATA2'多部分标识符“PCO.QUALIFICATIONCODE.code”无法绑定，但我不了解它的位置和原因。

我对这个问题很遗憾：/，我可以帮助一些查理大师吗？ 编辑查询不要伤害别人。 提前谢谢。

你的问题出在小组中。

你正在屏蔽你的领域＆＃34; ActividadesActivas。[CUSTOMDATA2]＆＃34;使用＆＃34; CUSTOMDATA2＆＃34; 

CASE
    WHEN (ActividadesActivas.[CUSTOMDATA2] IS NULL)
    THEN
      (SELECT Description
      FROM PCO_QUALIFICATIONCODE BIS
      WHERE SERVICEID = 1
      AND BIS.CODE    = SUBSTRING(CAST(PCO_QUALIFICATIONCODE.CODE AS VARCHAR), 1, 3)
      )
    ELSE ActividadesActivas.[CUSTOMDATA2]
  END CUSTOMDATA2,

所以，在小组中，你只能使用＆＃34; CUSTOMDATA2＆＃34;而不是＆＃34; ActividadesActivas。[CUSTOMDATA2]＆＃34; 

GROUP BY PCO_QUALIFICATIONCODE.CODE,
  ActividadesActivas.CUSTOMDATA2,
  ActividadesActivas.CUSTOMDATA3,
  Totales.TOTAL

PS：同样的规则应适用于剩余的字段。

编辑：我不确定这是否是您查询的唯一问题，但这就是您的问题＆＃34;无效的列名称＆＃39; CUSTOMDATA2＆＃39;＆＃34; < / p>
