Sql 获取要跨所有行显示的大小写表达式

我正在设置一个查询，需要在所有列中包含所有case表达式，而不是创建新行

我尝试添加case表达式，如代码所示。我还尝试在case表达式之前添加SUM

SELECT
  sum(Property.user_assignable) AS total_NASF,
  sum(Property.user_gross) AS total_GSF,
 Region.description As Region,
(CASE 
  WHEN UDF.Custom005 = 'Educational'
  Then SUM(Property.user_assignable)
  End) As Educational_NASF,
(CASE 
  WHEN UDF.Custom005 = 'Educational'
  Then sum(Property.user_gross)
  End) As Educational_GSF,
(CASE 
  WHEN UDF.Custom005 = 'Residence Hall'
  Then sum(Property.user_assignable)
  End) As Residential_NASF,
(CASE 
  WHEN UDF.Custom005 = 'Residence Hall'
  Then sum(Property.user_gross)
  End) As Residential_GSF,
(CASE 
  WHEN UDF.Custom005 = 'Hospital'
  Then sum(Property.user_assignable)
  End) As Hospital_NASF,
(CASE 
  WHEN UDF.Custom005 = 'Hospital'
  Then sum(Property.user_gross)
  End) As Hospital_GSF

FROM
  ae_s_bld_c Property
  Inner JOIN dbo.ae_s_bld_c_udf UDF ON (Property.multitenant_id = 
UDF.multitenant_id)
  AND (Property.bldg = UDF.bldg)
  AND (Property.fac_id = UDF.fac_id)
  AND (Property.region_code = UDF.region_code)
  Inner Join ae_b_reg_e Region ON Property.multitenant_id = 
region.multitenant_id
  AND Property.region_code = Region.region_code

WHERE
  (Property.bldg_status = 'ACTIVE' OR
  Property.bldg_status = 'VACANT' OR
  Property.bldg_status = 'CONSTRUCTION') AND
  Property.owned_leased = 'Y' AND
  Property.prop_type = 'BUILDING' AND
  Property.bldg_class <> 'Parking Struct' AND
  Property.region_code LIKE '28%'

  Group By
Region.description,
UDF.Custom005

---

预期结果（35行）

尝试将列从

CASE…SUM（）

更改为

SUM（CASE…

；例如改变：

(
  CASE 
    WHEN UDF.Custom005 = 'Educational'
    THEN SUM(Property.user_assignable)
  END
) AS Educational_NASF

确保您也从

分组依据

表达式中删除了字段

UDF.Custom005

。

这应该适用于您尝试执行的操作。 将

大小写

放入

总和

中，

真

部分返回列，

假

部分返回0

...
SUM(
  CASE
    WHEN UDF.Custom005 = 'Educational' Then Property.user_assignable
    ELSE 0
  End
) As Educational_NASF,
...

---

在本例中，所有行都被求和，但如果

时的
条件不匹配（即，当它不是
'Educational'
时），列值将被调零，因此求和结果只包含您想要的行。
简化您的问题！这是哪个数据库？Oracle？Microsoft SQL Server感谢Gents！！成功了。

SUM(
  CASE
    WHEN UDF.Custom005 = 'Educational' Then Property.user_assignable
    ELSE 0
  End
) As Educational_NASF,
