Question

here is my data,

Table 1:

             STORAGE    HANDLING    TOTAL BILLING 
             -------------------------------------- 
                 1300    10900     
                    0    10950     
                     0    6000     
                     0    5950     

Table 2:

 LINER REVENUE 
--------------- 
       1300 
        250 
       3000 
        200 

I need to calculate Total Billing:

I tried with this code.

UPDATE [dbo].[FCLOverall] SET [Total Revenue] = SELECT SUM([STORAGE]),      SUM([HANDLING]), SUM([LINER Revenue])
FROM (SELECT [STORAGE], [HANDLING],[Container No]
       FROM [dbo].[FCLOverall]
      UNION ALL
     SELECT [Container No],[LINER Revenue]
       FROM [dbo].[FCL_Child]) 

It is throwing some error missing brackets and invalid keyword select. is the query is right or wrong?

Can someone guide a query how to calculate on this?

Answer 1

does you find something below

 UPDATE [dbo].[FCLOverall]
    SET [Total Revenue] = 
   (SELECT SUM([STORAGE])+ SUM([HANDLING]) + SUM([LINER Revenue] ) as s
    FROM  (
        SELECT [Container No],[STORAGE], [HANDLING],0
           FROM [dbo].[FCLOverall]
          UNION ALL
         SELECT [Container No],0,0,[LINER Revenue]
           FROM [dbo].[FCL_Child]
             ) t ) 

Answer 2

Give this a try based on the assumption that Container No is key field.

UPDATE U
SET U.[Total Revenue] = COALESCE(U.Storage,0) + COALESCE(U.Handling,0) + COALESCE(FCLC.[Liner Revenue],0)
FROM dbo.FCLOverall AS U
INNER JOIN dbo.FCL_Child AS FCLC
  ON U.[Container No] = FCLC.[Container No]

Answer 3

Try this:

UPDATE FO 
SET [FO.Total Revenue] = ISNULL(FO.[STORAGE], 0) + ISNULL(FO.[HANDLING], 0) + ISNULL(FC.[LINER Revenue],0)
    FROM [dbo].[FCLOverall] AS FO
    INNER JOIN [dbo].[FCL_Child] FC on FO.[FO.Container No] = FC.[Container No]
