Sum a union query

I'm using Microsoft SQL Svr Mgmt Studio 2008. I don't have access to create a temporary table (company restricts ability to create or modify tables) or I would use that to solve this problem.

I have successfully used a union query to combine the results of three select queries. Now I am trying to sum the results of the union.

When I execute the query below I receive:

Incorrect syntax near the keyword 'GROUP'

And then when I remove the group by I get:

Incorrect syntax near ')'

Here's my query so far:

Select Period, PCC, SUM(BasicHits), SUM(FareHits), S开发者_StackOverflow中文版UM(SearchHits)
From (

SELECT     AAAPeriod AS Period, 
AAAFromPCC AS PCC, 
- SUM(AAABasic) AS BasicHits,
- SUM(AAAFare) AS FareHits,
- SUM(AAASearch) AS SearchHits
FROM        HitsAaa
HAVING     (AAAPeriod = N'2010-10') 

UNION ALL

SELECT     AAAPeriod, 
AAAtoPCC,
SUM(AAABasic),
SUM(AAAFare),
SUM(AAASearch) 
FROM        HitsAaa
HAVING     (AAAPeriod = N'2010-10')

UNION ALL

SELECT      AgtPeriod, 
AgtPcc, 
SUM(AgtBasic),
SUM(AgtFare),
SUM(AgtSearch)
FROM          HitsAgent
HAVING      (AgtPeriod = N'2010-10')

)GROUP BY Period, PCC

I haven't been able to find a solution to this on any of the previous questions.

You need to alias your derived table, you must also use a group by with a having clause.

SELECT
  q1.Period, 
  q1.PCC, 
  SUM(q1.BasicHits), 
  SUM(q1.FareHits), 
  SUM(q1.SearchHits)
FROM (SELECT     
        AAAPeriod AS Period, 
        AAAFromPCC AS PCC, 
        - SUM(AAABasic) AS BasicHits,
        - SUM(AAAFare) AS FareHits,
        - SUM(AAASearch) AS SearchHits
      FROM HitsAaa
      GROUP BY 
        AAAPeriod, 
        AAAFromPCC
      HAVING (AAAPeriod = N'2010-10') 

      UNION ALL

      SELECT     
        AAAPeriod AS Period, 
        AAAtoPCC AS PCC,
        SUM(AAABasic) AS BasicHits,
        SUM(AAAFare) AS FareHits,
        SUM(AAASearch) AS SearchHits 
      FROM HitsAaa
      GROUP BY 
        AAAPeriod, 
        AAAtoPCC
      HAVING (AAAPeriod = N'2010-10')

      UNION ALL

      SELECT
        AgtPeriod AS Period, 
        AgtPcc AS PCC, 
        SUM(AgtBasic) AS BasicHits,
        SUM(AgtFare) AS FareHits,
        SUM(AgtSearch)  AS SearchHits
      FROM HitsAgent
      GROUP BY 
        AgtPeriod, 
        AgtPCC
      HAVING (AgtPeriod = N'2010-10')) q1 
GROUP BY 
  q1.Period, 
  q1.PCC

SQL Server requires that you define a table alias for a derived table/inline view:

SELECT x.period, x.pcc, SUM(x.BasicHits), SUM(x.FareHits), SUM(x.SearchHits)
  FROM (SELECT AAAPeriod AS Period, 
               AAAFromPCC AS PCC, 
               - SUM(AAABasic) AS BasicHits,
               - SUM(AAAFare) AS FareHits,
               - SUM(AAASearch) AS SearchHits
          FROM HitsAaa
         WHERE AAAPeriod = N'2010-10'
      GROUP BY aaaperiod, aaafrompcc
        UNION ALL
        SELECT AAAPeriod, 
               AAAtoPCC,
               SUM(AAABasic),
               SUM(AAAFare),
               SUM(AAASearch) 
          FROM HitsAaa
         WHERE AAAPeriod = N'2010-10'
      GROUP BY aaaperiod, aaafrompcc
        UNION ALL
        SELECT AgtPeriod, 
               AgtPcc, 
               SUM(AgtBasic),
               SUM(AgtFare),
               SUM(AgtSearch)
          FROM HitsAgent
         WHERE AgtPeriod = N'2010-10'
      GROUP BY agtperiod, agtpcc) AS x
GROUP BY x.period, x.pcc

I don't have access to create a temporary table (company restricts ability to create or modify tables) or I would use that to solve this problem.

Instead of a temporary table, try using a table variable:

declare @t table (id int primary key, col1 varchar(50))
insert @t (col1) values ('hello table variable')
select * from @t

A table variable can do most of the things a temporary table can.

Like Martin's (now deleted) answer suggests, consider giving the subquery an alias, like:

select  ... list of columns ...
from    (
        ... subquery ...
        ) as SubQueryAlias
group by
        col1

And in your subquery, the having should probably be a where:

...
FROM        HitsAaa
WHERE       (AAAPeriod = N'2010-10') 
...

Change your first line to

Select T.Period, T.PCC, SUM(T.BasicHits), SUM(T.FareHits), SUM(T.SearchHits)

and the last line to

) T GROUP BY T.Period, T.PCC

You need to define a table alias (in this case T) for inner tables

Also, you need to GROUP BY the inner queries

select R."Artigo", R."Dscription" as "Descricao", R."Codigo", R."Cliente", R."ItmsGrpCod", Sum(R."Qtd/Kg") as "Qtd/Kg", Sum(R."Valor") as "Valor", Sum(R."Valor")/Sum(R."Qtd/Kg") as "PMVL" from ( select T1."ItemCode" as "Artigo", T1."Dscription", T0."CardCode" as "Codigo", T0."CardName" as "Cliente", T3."ItmsGrpCod", Sum(T1."Quantity")-1 as "Qtd/Kg", Sum(T1."LineTotal")-1 as "Valor", ( Sum(T1."LineTotal") / Sum(T1."Quantity") ) as "PMVL" from ORIN T0 INNER JOIN RIN1 T1 ON T0."DocEntry" = T1."DocEntry" RIGHT JOIN OITM T3 ON T1."ItemCode" = T3."ItemCode" LEFT JOIN IBT1 T2 ON T0."DocEntry" = T2."BaseEntry" AND T1."ItemCode"=T2."ItemCode" and T2."BaseLinNum"=T1."LineNum" where T0."DocDate" >= ('2021-03-19') and T0."DocDate" <= ('2021-03-19') and T3."ItmsGrpCod" like '___' and T0.CANCELED = 'N' group by T1."ItemCode", T1."Dscription", T0."CardCode", T0."CardName", T3."ItmsGrpCod" union -- facturas

select T1."ItemCode" as "Artigo", T1."Dscription", T0."CardCode" as "Codigo", T0."CardName" as "Cliente", T3."ItmsGrpCod", Sum(T1."Quantity") as "Qtd/Kg", Sum(T1."LineTotal") as "Valor", ( Sum(T1."LineTotal") / Sum(T1."Quantity") ) as "PMVL" from OINV T0 INNER JOIN INV1 T1 ON T0."DocEntry" = T1."DocEntry" -- LEFT JOIN OITM T3 ON T1."ItemCode" = T3."CardCode" left JOIN OITM T3 ON T1."ItemCode" = T3."ItemCode" -- INNER JOIN OITM T3 ON T3."ItemCode" = T3."CardCode" LEFT JOIN IBT1 T2 ON T0."DocEntry" = T2."BaseEntry" AND T1."ItemCode"=T2."ItemCode" and T2."BaseLinNum"=t1."LineNum"

    where T0."DocDate"  >= ('2021-03-19') and T0."DocDate" <= ('2021-03-19') 
    and T3."ItmsGrpCod" like '___' 
    group by T1."ItemCode", T1."Dscription", T0."CardCode", T0."CardName",T3."ItmsGrpCod"
    ) as R
    group by R."Artigo", R."Dscription", R."Codigo", R."Cliente",R."ItmsGrpCod"
