Is it possible to add a case using a column from other tables than first in the from section?
I can't use anything like C.code or Y.anything in the SELECT part:
SELECT
fromTableA, fromTableA, fromTableA,
CASE
WHEN fromTableA = anyValue THEN 'is_ok'
WHEN B.fromTableB = anyValue THEN 'couldnt.be.bound'
WHEN fromTableB = anyValue THEN 'invalid.column.name'
END AS X
FROM
(SELECT fromTableA,
SUM(fromTableA),
CASE WHEN A.fromTableA = 'anything' THEN 'still ok'
WHEN C.fromTableC = 'allowed' THEN 'no problem'
FROM tableA A
JOIN tableB B ON A.id = B.id
JOIN tableC C ON C.id = B.id
Having SUM(fromTableA) > 0
) AS Y
Edit: What I need is to use columns from table B or C in the outer Select ( I just can't remove the inner select because i would lost cases and aggregation operations there are in the inner select).
The following should be all you need, a derived table here doesn't accomplish anything.
select A.Cols...,
case
when A.col1 = anyValue then 'is_ok'
when B.Col1 = anyValue then 'couldnt.be.bound'
when B.Col2 = anyValue then 'invalid.column.name'
end as X
from tableA A
join tableB B on A.id = B.id
join tableC C on C.id = B.id;

My Query IS
SELECT TblPharmacyBillingDetails.UPBNo, TblMasterBillingData.IPDNo, InPatRegistration.PatTitle+PatientName, TblPharmacyBillingDetails.InvoiceNo, TblPharmacyBillingDetails.InvoiceDateTime, TblPharmacyBillingDetails.BillingAmount
FROM TblPharmacyBillingDetails
INNER JOIN TblMasterBillingData ON TblPharmacyBillingDetails.UPBNo = TblMasterBillingData.UPBNo
INNER JOIN InPatRegistration ON TblMasterBillingData.IPDNo = InPatRegistration.IPDNo
but if TblMasterBillingData.IPDNo value is NULL select Data From TblMasterBillingData.OPDNo and
INNER JOIN OutPatRegistration ON TblMasterBillingData.OPDNo = OutPatRegistration.IPDNo
Method #1: Using UNION
SELECT * FROm
(
SELECT TblPharmacyBillingDetails.UPBNo,
TblMasterBillingData.IPDNo,
InPatRegistration.PatTitle+PatientName,
TblPharmacyBillingDetails.InvoiceNo,
TblPharmacyBillingDetails.InvoiceDateTime,
TblPharmacyBillingDetails.BillingAmount
FROM TblPharmacyBillingDetails
INNER JOIN TblMasterBillingData ON TblPharmacyBillingDetails.UPBNo = TblMasterBillingData.UPBNo
INNER JOIN InPatRegistration ON TblMasterBillingData.IPDNo = InPatRegistration.IPDNo
WHERE TblMasterBillingData.IPDNo IS NOT NULL
UNION ALL
SELECT TblPharmacyBillingDetails.UPBNo,
TblMasterBillingData.OPDNo,
OutPatRegistration .PatTitle + PatientName,
TblPharmacyBillingDetails.InvoiceNo,
TblPharmacyBillingDetails.InvoiceDateTime,
TblPharmacyBillingDetails.BillingAmount
FROM TblPharmacyBillingDetails
INNER JOIN TblMasterBillingData ON TblPharmacyBillingDetails.UPBNo = TblMasterBillingData.UPBNo
INNER JOIN OutPatRegistration ON TblMasterBillingData.OPDNo = OutPatRegistration.OPDNo
WHERE TblMasterBillingData.OPDNo IS NOT NULL
)Tmp
ORDER BY TblPharmacyBillingDetails.UPBNo
Method #2 Using ISNULL and LEFT JOIN
SELECT TblPharmacyBillingDetails.UPBNo,
ISNULL(TblMasterBillingData.IPDNo,TblMasterBillingData.OPDNo),
ISNULL(IP.PatTitle + IP.PatientName, OP.PatTitle + OP.PatientName),
TblPharmacyBillingDetails.InvoiceNo,
TblPharmacyBillingDetails.InvoiceDateTime,
TblPharmacyBillingDetails.BillingAmount
FROM TblPharmacyBillingDetails
INNER JOIN TblMasterBillingData ON TblPharmacyBillingDetails.UPBNo = TblMasterBillingData.UPBNo
LEFT JOIN InPatRegistration IP ON TblMasterBillingData.IPDNo = IP.IPDNo
LEFT JOIN outPatRegistration OP ON TblMasterBillingData.OPDNo = OP.OPDNo
ORDER BY TblPharmacyBillingDetails.UPBNo
You can write either case statement or ISNULL() function as shown below in the demo query.
SELECT
Orders.OrderID,
Case when Customers1.CustomerName is null then Customers2.CustomerName else Customers1.CustomerName
end as CustomerName, --way 1
ISNULL(Customers1.CustomerName, Customers2.CustomerName) as Customer, --way 2
Orders.OrderDate
FROM Orders
INNER JOIN Customers1 ON Orders.CustomerID = Customers1.CustomerID
INNER JOIN Customers2 ON Orders.CustomerID = Customers2.CustomerID
-- where your condition here
-- order by your column name
You can also check whether data is available or not in the table and join the table accordingly using if exists as shown below.
if exists(select 1 from tablename where columnname = <your values>)
I have a query as follows:
select --this select should always give me 1 record
tbl1.Id, tbl1.Name, tbl1.Address, tbl2.relNo,
CASE WHEN tbl3.Comments IS NOT NULL THEN 1 ELSE 0 END AS 'Required'
from
table1 tbl1
inner join
table2 tbl2 on tbl2.Id = tbl1.Id
left join -- This left join table gives me 5 records for one instance
(select
R.Id, C.Comments
from
tblC C
inner join
tblR R on R.Id = C.id) tbl3 on tbl3.Id = tbl2.Id
I want to write a CASE statement on the rows my left join is giving to check for null value as above and my final select query always return only 1 row. Is there a way to check if all five Comments Column values from my left join be checked for NULLs in the above query?
I would take a shortcut an use a COUNT() OVER PARTITION
CASE WHEN COUNT(*) OVER (PARTITION BY tbl3.Id) =0 THEN 0 ELSE 1 END AS 'Required'
You would have to DISTINCT your output above. Another option would be to GROUP BY and filter in the HAVING clause.
select --this select should always give me 1 record
tbl1.Id, tbl1.Name, tbl1.Address, tbl2.relNo
From table1 tbl1
inner join table2 tbl2 on tbl2.Id = tbl1.Id
left join (-- This left join table gives me 5 records for one instance
SELECT R.Id,
C.Comments
FROM tblC C
INNER JOIN tblR R on R.Id = C.id
) tbl3 on tbl3.Id = tbl2.Id
GROUP BY
Id, Name, Address, relNo
HAVING
COUNT(*) = 5
Is this what you're looking for?
(CASE WHEN (select count(tbl3.id) FROM tbl3 WHERE tbl3.Comments IS NULL) then 1 else 0 end) as 'RequiredVal'
select --this select should always give me 1 record
tbl1.Id, tbl1.Name, tbl1.Address, tbl2.relNo,
CASE WHEN tbl3.Comments IS NOT NULL THEN 1 ELSE 0 END AS 'Required'
, (CASE WHEN (select count(tbl3.id) FROM tbl3 WHERE tbl3.Comments IS NULL) then 1 else 0 end) as 'RequiredVal'
From table1 tbl1
inner join table2 tbl2 on tbl2.Id = tbl1.Id
left join (-- This left join table gives me 5 records for one instance
SELECT R.Id,
C.Comments
FROM tblC C
INNER JOIN tblR R on R.Id = C.id
) tbl3 on tbl3.Id = tbl2.Id
I have two tables with same columns.
Table A have ID, Name, Des, Status and
Table B have ID, Name, Des, Status.
I want to compare data any field of Table B with Table A, except column ID because same.
As same picture above, when FETCH data of Table B, detect data of ID ID001 and ID003 not same, idea of my mind same
IF (SELECT COUNT (SELECT * FROM TABLE A RIGHT JOIN TABLE B ON A.ID = B.ID) != 0)
BEGIN
PRINT 'BLAH BLAH, NOT SAME'
END
If you have idea or solution, share for me, Thank you so much.
You can use CHECKSUM or BINARY_CHECKSUM:
SELECT a.*, b.*
FROM TableA a INNER JOIN TableB b ON b.ID = a.ID
WHERE CHECKSUM(b.Name, b.Des, b.Status) <> CHECKSUM(a.Name, a.Des, a.Status)
See also this link. It should be faster then multiple OR conditions.
IF (SELECT COUNT(*)
FROM TableA a INNER JOIN TableB b ON b.ID = a.ID
WHERE BINARY_CHECKSUM(b.Name, b.Des, b.Status)
<> BINARY_CHECKSUM(a.Name, a.Des, a.Status)
>0
PRINT 'Not the same.'
Since it is not too much clear how do you want to show your differences, this is one approach:
SELECT A.ID,
(CASE WHEN A.Name <> B.Name THEN 'Diff Name' ELSE '') NameCompare,
(CASE WHEN A.Des <> B.Des THEN 'Diff Des' ELSE '') DESCompare,
(CASE WHEN A.Status <> B.Status THEN 'Diff Status' ELSE '') StatusCompare
FROM A
INNER JOIN B
ON A.ID = B.ID
This is a simple join
To get all different rows, you can say:
select a.*, b.*
from TableA a inner join TableB b on b.ID = a.ID
where b.Name <> a.Name or b.Des <> a.Des or b.Status <> a.Status
I have 2 tables on which join is there.
for second table TableB i am fetching both id and post.
SELECT a.id,
a.NAME,
b.id,
b.post
FROM tableA a
INNER JOIN tableB b
ON a.bid = b.id
But in one case b.id=3 i have post ='manager' but i have to show post='associate manager'. i cannot change table values but only query.
I am currently using replace .
SELECT a.id,
a.NAME,
b.id,
replace(b.post, 'manager', 'associate manager')
FROM tableA a
INNER JOIN tableB b
ON a.bid = b.id
Should i switch to case or this is correct.
Regards,
Use Case Statement
SELECT a.id,
a.NAME,
b.id,
CASE
WHEN b.id = 3 THEN 'associate manager'
ELSE post
END
FROM tableA a
INNER JOIN tableB b
ON a.bid = b.id
I want to show/display if the product is found each transaction.

I tried, INNER JOIN, FULL OUTER JOIN, LEFT JOIN and RIGHT JOIN but I don't get the exact data I need.
Here are the queries I test.
SELECT * FROM tblProducts a INNER JOIN tblTransactions b ON a.PRODCODE = b.PRODCODE
SELECT * FROM tblProducts a FULL OUTER JOIN tblTransactions b ON a.PRODCODE = b.PRODCODE
SELECT * FROM tblProducts a LEFT JOIN tblTransactions b ON a.PRODCODE = b.PRODCODE
SELECT * FROM tblProducts a RIGHT JOIN tblTransactions b ON a.PRODCODE = b.PRODCODE
I'm pretty sure this works - SQLFiddle here: http://sqlfiddle.com/#!3/65eb1/23
WITH AllVals AS
(SELECT a.PRODCODE, b.TCODE
FROM tblProducts a
CROSS JOIN tblTransactions b)
SELECT DISTINCT c.PRODCODE,
c.TCODE,
CASE WHEN d.PRODCODE IS NULL THEN 'NO' ELSE 'YES' END AS FOUND
FROM AllVals c
LEFT OUTER JOIN tblTransactions d
ON c.PRODCODE = d.PRODCODE
AND c.TCODE = d.TCODE
http://sqlfiddle.com/#!3/65eb1/24
select DT.TCODE, DT.PRODCODE, case when (Tr2.TCODE IS null and Tr2.PRODCODE IS null) then 'No' else 'Yes' END as FOUND
from tblTransactions Tr2 right join
(
select distinct Tr.TCODE, p.PRODCODE
from tblProducts p cross join tblTransactions Tr
) DT
on DT.PRODCODE = Tr2.PRODCODE and DT.TCODE = Tr2.TCODE;
