sql - sql查询中如何对一个字段中的多个字段求和？

Question

我在输入中得到了很多代码，这段代码有一个父级

SELECT [fromAccCode]= 
CASE WHEN [fromAccCode] IN (201010, 201020, 201442, 201521, 201611,201612,209050,
209060,209090,209110,213040,213163,213165,213166,213190) THEN r1
WHEN [fromAccCode] IN (201040, 201048, 201050, 201090, 201120, 201150
,201155) THEN r2
WHEN [fromAccCode] IN (201443,206020,207010,207040,207100,207130,209612
) THEN r3

我用这段代码设置了输入

SELECT [fromAccCode] FROM [dbo].[source_table] WHERE ','+'201010, 
201020,259861,754265,213040,213163,213165,201040,
201048, 201050,201443,206020'+',' like '%,'+cast([fromAccCode] 
AS varchar(10))+',%'

我希望你有 3 记录 1,2,3 形式 sum 的值 (r1),值的总和(r2) 和值的总和(r3) 并且这个字段有值

Answer 1

首先:添加一个字段来设置案例数

  select  [fromAccCode], --your code
field_name=  --add this code
          CASE 
      WHEN [fromAccCode] IN (201010,201020,201442,201521,201611,201612,209050,209060,209090,209110,213040,213163,213165,213166,213190) THEN 'r1         
      WHEN [fromAccCode] IN (201040,201048,201050,201090,201120,201150,201155) THEN r2
      WHEN [fromAccCode] IN (201443,206020,207010,207040,207100,207130,209612) THEN r3     
               ELSE null
          END   

您不需要此代码段:

WHERE ',' + '201010,201020,259861,754265,213040,213163,213165,201040,201048,201050,201443,206020' + ',' 
  LIKE CONCAT('%,', [fromAccCode], ',%')

因为你有 fromAccCode 值

第二个:

 select [fromAccCode ]
  ,[field_name]
  ,sum([value])
   from #result_table  group by [fromAccCode ]
  ,[field_name]
  ,[value]
