It is a bit complicated query but let me elaborate,
i have got multiple filter parameters in my procedure,
also a view named Vw1 and its regarded my main object in query that most of the filter parameters are filtered against this view that is located in another server,then i need to compare this view to another table and check two sides columns for possible conflict and then check if there is any conflict.
you can see my query below

due to performance issues i had to write it in dynamic way,But the problem is that i could not wrap my head around paging in this query, bacause as you see i should put paging line in the end of query because #HasConflict parameters exist and i cannot check it earlier,and in this way my paging seems pointless because i'm dealing with huge load of data ...
also i cannot use offset for paging because my sql version is too old ...
Here is a sample below, I want to update AvailableAmt column based on the amount entered on UI.
Requirement
Update the value from the last row to the first row,
If entered 500 on UI, then the table will be like
If entered 1000 on UI, then the table will be like
Thank you for your help in advance !
Can't test it on a Sybase somewhere.
But in theory something like this might work:
DECLARE #Group VARCHAR(8) = 'a';
DECLARE #Amount INT = 1100;
UPDATE t
SET t.AvailableAmt =
CASE
WHEN q.PrevRemain > 0 AND t.AvailableAmt <= q.PrevRemain THEN 0
WHEN q.PrevRemain > 0 THEN t.AvailableAmt - q.PrevRemain
ELSE t.AvailableAmt
END
FROM YourTable t
JOIN
(
select [Group], [Row],
#Amount-(SUM(AvailableAmt) OVER (PARTITION BY [Group] ORDER BY AvailableAmt, [Row] desc) - AvailableAmt) as PrevRemain
from YourTable
where AvailableAmt > 0
and [Group] = #Group
) AS q
ON (q.[Group] = t.[Group] and q.[Row] = t.[Row]);
For a Sybase flavor that doesn't support the window function of SUM, something like this might work.
DECLARE #Group VARCHAR(8) = 'a';
DECLARE #Amount INT = 1200;
UPDATE t
SET t.AvailableAmt =
CASE
WHEN q.PrevRemain > 0 AND t.AvailableAmt <= q.PrevRemain THEN 0
WHEN q.PrevRemain > 0 THEN t.AvailableAmt - q.PrevRemain
ELSE t.AvailableAmt
END
FROM YourTable t
JOIN
(
select t1.[Group], t1.[Row],
#Amount - (SUM(t2.AvailableAmt)-t1.AvailableAmt) as PrevRemain
from YourTable t1
left join YourTable t2 on (t2.[Group] = t1.[Group] and t2.AvailableAmt <= t1.AvailableAmt and t2.[Row] >= t1.[Row])
where t1.AvailableAmt > 0
and t1.[Group] = #Group
group by t1.[Group], t1.[Row], t1.AvailableAmt
) AS q
ON (q.[Group] = t.[Group] and q.[Row] = t.[Row]);
I have a query that is using a LEFT OUTER JOIN to merge 2 data sets. I know both data sets should return data because I ran the superquery and the subquery separately. For some reason, the query is returning zero results. Anyone know why?
Left data:
item FG_lots
447845 E2211
Right data:
candy_lot_check candy_item
L2211 835116
Intended result:
item FG_lots candy_lot_check candy_item

The result from my broken query (no results):
item FG_lots candy_lot_check candy_item

You've got two 't' aliases, try altering it.
It seems you could rewrite it to make it more readable (joinwise, not indentwise), it could be that something's not right in the logic as well
I have a stored procedure that returns an integer 1 or 0 depending on specific criteria. It currently uses three select statements and it will be used heavily by multiple users across multiple locations. There has to be a more efficient way of doing this.
In short the query checks first to see if all checklist items on an order are completed (a separate table), then it checks to see if a field named BreakOutGuest (a bit field) is a 1 or 0. Depending on that result it checks to see if the total guest count is greater than 0 and the order total is zero. It returns the one or zero on all this criteria. Is there a more efficient way to do this? A temp table so I only have to hit the actual tables once? Below is the code.
#ORDERID INT
AS
BEGIN
DECLARE #AUTO_CLOSE INT
SET NOCOUNT ON;
--If all checklist items are marked complete move on, if not set #AUTO_CLOSE=0
IF NOT EXISTS(SELECT ORDERID FROM dbo.orderchecklistitems WHERE OrderID=#ORDERID AND CompletedON IS NULL)
BEGIN
--if BreakOutGuestFees is 1 only sum Guest_Count_1 + Guest_Count_2
IF EXISTS(SELECT * FROM dbo.Orders WHERE (GuestCount_1 + GuestCount_2)>1 AND OrderTotal=0 AND BreakoutGuestFees=1)
BEGIN
SET #AUTO_CLOSE=1
END
ELSE
SET #AUTO_CLOSE=0
--if BreakOutGuestFees is 0 only consider Guest_Count_1
IF EXISTS(SELECT * FROM dbo.Orders WHERE (GuestCount_1)>1 AND OrderTotal=0 AND BreakoutGuestFees=0)
BEGIN
SET #AUTO_CLOSE=1
END
ELSE
SET #AUTO_CLOSE=0
END
ELSE
SET #AUTO_CLOSE=0
END
If am not wrong you can combine two if clause into single if clause by using AND , OR logic. Try this.
IF NOT EXISTS(SELECT ORDERID
FROM dbo.orderchecklistitems
WHERE OrderID = #ORDERID
AND CompletedON IS NULL)
BEGIN
IF EXISTS(SELECT *
FROM dbo.Orders
WHERE ( ( GuestCount_1 + GuestCount_2 > 1
AND BreakoutGuestFees = 1 )
OR ( BreakoutGuestFees = 0
AND GuestCount_1 > 1 ) )
AND OrderTotal = 0
AND OrderID = #ORDERID)
SET #AUTO_CLOSE=1
ELSE
SET #AUTO_CLOSE=0
END
ELSE
SET #AUTO_CLOSE=0
You can perform your selection check with only one query
SELECT
(SELECT sum(1) FROM dual WHERE EXISTS (SELECT ORDERID FROM dbo.orderchecklistitems WHERE OrderID=#ORDERID AND CompletedON IS NULL)),
(SELECT sum(1) FROM dual WHERE EXISTS (SELECT 1 FROM dbo.Orders WHERE (GuestCount_1 + GuestCount_2)>1 AND OrderTotal=0 AND BreakoutGuestFees=1)),
(SELECT sum(1) FROM dual WHERE EXISTS (SELECT 1 FROM dbo.Orders WHERE (GuestCount_1)>1 AND OrderTotal=0 AND BreakoutGuestFees=0))
INTO
result1, result2, result3
from dual
then check results
DELCARE #AUTO_CLOSE INT = 0
IF NOT EXISTS(SELECT ORDERID
FROM dbo.orderchecklistitems
WHERE OrderID = #ORDERID
AND CompletedON IS NULL)
BEGIN
SET #AUTO_CLOSE =
(
SELECT
CASE
WHEN (GuestCount_1 + GuestCount_2 > 1) AND BreakoutGuestFees = 0 THEN 1
WHEN (GuestCount_1 > 1 ) AND BreakoutGuestFees = 1 THEN 1
ELSE 0 END
FROM dbo.orders
WHERE OrderTotal = 0 AND OrderID = #orderID

I am unable to update the data using record by record below scenario.
Required output: patient will able to Admit/Re-admit multiple times in hospital, if a patient readmitted multiple times in hospital after the first visit, first visit record will get Re-admission=0 and Index=1. This visit should cal Index_Admission of that patient. using this index_admission should calculate the 30-day readmission.
Current Output:
Calculation:
From index_admission discharge date to next admit_visit date,
1) if the diff is having less than 30 days, readmission=1 and Index=0
else readmission=0 and Index=1 should be update.
For checking this every time should check using the latest index_admission discharge_date.
To get this result i written below logic, but it's updating readmission=0 and Index=1 after 30-day post discharge of using first index admission.
UPDATE Readmission
SET Index_AMI = (CASE
WHEN DATEDIFF(DD, (SELECT
Sub.Max_Index_Dis
FROM (SELECT
Patient_ID,
MAX(Discharge_Date_Time) Max_Index_Dis
FROM Readmission
WHERE Index_AMI = 1 AND FPR.Patient_ID = Patient_ID
GROUP BY Patient_ID) Sub), FPR.Admit_Date_Time) <= 31 THEN 0 ELSE 1
END),
Is_AMI_Readmission = (CASE
WHEN DATEDIFF(DD, (SELECT
Sub.Max_Index_Dis
FROM (SELECT
Patient_ID,
MAX(Discharge_Date_Time) Max_Index_Dis
FROM Readmission
WHERE Index_AMI = 1 AND FPR.Patient_ID = Patient_ID
GROUP BY Patient_ID) Sub)
, FPR.Admit_Date_Time) <= 31 THEN 1 ELSE 0
END)
FROM Readmission FPR
WHERE fpr.index_ami IS NULL
Expected Result:
Please help me to resolve the issue.

Thank you all for trying to help.
I some how managed to solve it using temporary tables.
If there is any issues, especially performance, with this approach please feel free to comment/criticize.
