The multi-part identifier "Transaction_tbl.locid" could not be bound while using join in case statement in sql server - sql

Question

I have a query like this:
select sum(status_receved) as Receved, sum(status_parked) as Parked,
sum(status_requested) as Requested,sum(status_requestedinprocess) as Requestinprocess,
sum(status_deliverd) as Deliverd
from (select case when (status = 0 ) then 1 else 0 end as status_receved,
case when (status = 2) then 1 else 0 end as status_parked,
case when (status = 3) then 1 else 0 end as status_requested,
case when(status=4) then 1 else 0 end as status_requestedinprocess,
case when(Status=5) then 1 else 0 end status_deliverd
from transaction_tbl where locid in(5) and status in (0,2,3,4)) a
this query is working fine. i am getting result like this:
Receved Parked Requested Requestinprocess Deliverd
----------- ----------- ----------- ---------------- -----------
1 37 0 3 0
I also have a location_master table, and I want to show the corresponding location name before. My locid=5 is Bur dubai. I tried to write a query something like this:
SELECT LocName ,
SUM(status_receved) AS Receved ,
SUM(status_parked) AS Parked ,
SUM(status_requested) AS Requested ,
SUM(status_requestedinprocess) AS Requestinprocess ,
SUM(status_deliverd) AS Deliverd
FROM ( SELECT l.LocName ,
CASE WHEN ( status = 0 ) THEN 1
ELSE 0
END AS status_receved ,
CASE WHEN ( status = 2 ) THEN 1
ELSE 0
END AS status_parked ,
CASE WHEN ( status = 3 ) THEN 1
ELSE 0
END AS status_requested ,
CASE WHEN ( status = 4 ) THEN 1
ELSE 0
END AS status_requestedinprocess ,
CASE WHEN ( Status = 5 ) THEN 1
ELSE 0
END status_deliverd
FROM transaction_tbl t
INNER JOIN Location_tbl l ON l.Locid = t.locid
WHERE t.Locid IN ( 5 )
AND status IN ( 0, 2, 3, 4 )
) a;
But I am getting this error:Column 'a.LocName' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
The result I would like to get is this:
Location Receved Parked Requested Requestinprocess Deliverd
--- ----------- ----------- ----------- ---------------- -----------
Burdubai 1 37 0 3 0

It seems that SQL Server was installed with case-sensitive option. You can check: execute sp_server_info and look at 18 COLLATION_SEQ on sort_order.
On my server it is set to nocase_iso that means if you already have Column A column in a table you can not add a column: they are the same if sort_order is set to nocase_iso.
If so then just change on l.Locid=t.locid to proper case on l.Locid=t.Locid
Also in your query you are selecting l.LocName from subquery that doesn't return LocName column. Rewrite as
SELECT LocName ,
SUM(status_receved) AS Receved ,
SUM(status_parked) AS Parked ,
SUM(status_requested) AS Requested ,
SUM(status_requestedinprocess) AS Requestinprocess ,
SUM(status_deliverd) AS Deliverd
FROM ( SELECT l.LocName ,
CASE WHEN ( status = 0 ) THEN 1
ELSE 0
END AS status_receved ,
CASE WHEN ( status = 2 ) THEN 1
ELSE 0
END AS status_parked ,
CASE WHEN ( status = 3 ) THEN 1
ELSE 0
END AS status_requested ,
CASE WHEN ( status = 4 ) THEN 1
ELSE 0
END AS status_requestedinprocess ,
CASE WHEN ( Status = 5 ) THEN 1
ELSE 0
END status_deliverd
FROM transaction_tbl t
INNER JOIN Location_tbl l ON l.Locid = t.locid
WHERE t.Locid IN ( 5 )
AND status IN ( 0, 2, 3, 4 )
) a
GROUP BY LocName;
