SELECT

    CCDMS_Container.ContainerID, CCDMS_Container.Price, 
    SUM(CASE WHEN CCDMS_Container.ContainerSize = 1
             THEN 1 ELSE 0 END) AS size1,
    SUM(CASE WHEN CCDMS_Container.ContainerSize = 2
             THEN 1 ELSE 0 END) AS size2,
    SUM(CASE WHEN CCDMS_Container.ContainerSize = 3
             THEN 1 ELSE 0 END) AS size3,
    SUM(CASE WHEN CCDMS_Container.ContainerSize = 4
             THEN 1 ELSE 0 END) AS size4,
    SUM(CASE WHEN CCDMS_Container.ContainerSize = 5
             THEN 1 ELSE 0 END) AS size5
FROM 
    CCDMS_Company
INNER JOIN 
    CCDMS_Container ON CCDMS_Container.Co_ID = CCDMS_Company.CompanyID
                    AND CCDMS_Company.CityID = 1
GROUP BY 
    CCDMS_Company.CompanyID, CCDMS_Company.CompanyName,
    CCDMS_Container.ContainerID, CCDMS_Container.Price
HAVING
    size1 >=2
    AND size2 >= 1
    AND size3 >= 1
    AND size4 >= 0
    AND size5 >= 1 ;

This is my query and I keep getting this error even when I use where .

I don't know what to do .

Incorrect syntax near the keyword 'having'.

Answer 1

You can not use alias in having. Use below instead, or use CTE for simplicity

select CCDMS_Company.CompanyID , CCDMS_Company.CompanyName ,
CCDMS_Container.ContainerID ,CCDMS_Container.Price , 
sum(case when CCDMS_Container.ContainerSize=1
 then 1 else 0 end)as size1,
sum(case when CCDMS_Container.ContainerSize=2
 then 1 else 0 end)as size2,
sum(case when CCDMS_Container.ContainerSize=3
 then 1 else 0 end)as size3,
sum(case when CCDMS_Container.ContainerSize=4
 then 1 else 0 end)as size4,
sum(case when CCDMS_Container.ContainerSize=5
 then 1 else 0 end)as size5
   from 
CCDMS_Company
 inner join
CCDMS_Container
on CCDMS_Container.Co_ID = CCDMS_Company.CompanyID
and 
CCDMS_Company.CityID = 1
group by 
CCDMS_Company.CompanyID,CCDMS_Company.CompanyName,CCDMS_Container.ContainerID,CCDMS_Container.Price

having
    sum(case when CCDMS_Container.ContainerSize=1 then 1 else 0 end) >=2
and sum(case when CCDMS_Container.ContainerSize=2 then 1 else 0 end) >= 1
and sum(case when CCDMS_Container.ContainerSize=3 then 1 else 0 end) >= 1
and sum(case when CCDMS_Container.ContainerSize=4 then 1 else 0 end) >= 0
and sum(case when CCDMS_Container.ContainerSize=5 then 1 else 0 end) >= 1

Answer 2

You can't reference the aliases from your select statement in the having statement. Try rebuilding your query using a subquery to filter it.
