I want to do rolling sum of column. I have created following query
SET #FinancialIncremental:=0;
SELECT j.ErrorCategory,
COUNT(IF(j.ErrorType = 'P',j.ErrorType,NULL)) AS Financial,
COUNT(IF(j.ErrorType = 'NP',j.ErrorType,NULL)) AS Procedural,
SUM(j.OverPaymentAmount) AS 'Financial Over Paid Amount ($)',
(
SELECT
#FinancialIncremental := #FinancialIncremental + q1.c
FROM
(
(SELECT
COUNT(IF(ErrorType = 'P',ErrorType,NULL)) AS c
FROM DemoScheme.TestTable WHERE IsDeleted = 0 AND ErrorType IN ('P','NP')
GROUP BY ErrorCategory) AS q1
)
) AS 'Financial Incremental'
FROM DemoScheme.TestTable j WHERE IsDeleted = 0 AND ErrorType IN ('P','NP')
GROUP BY ErrorCategory;
But It is giving me an error. It giving me an error on 'Financial Incremental' subquery
Error Code: 1242. Subquery returns more than 1 row
Can anybody help me to solve this?
You have some repetitions in there which complicate things unnecessarily,try this query.You might also need to replace NULL with 0 when you add it.
SET #FinancialIncremental:=0;
SELECT j.ErrorCategory,
COUNT(IF(j.ErrorType = 'P',j.ErrorType,NULL)) AS Financial,
COUNT(IF(j.ErrorType = 'NP',j.ErrorType,NULL)) AS Procedural,
SUM(j.OverPaymentAmount) AS 'Financial Over Paid Amount ($)',
(#FinancialIncremental := #FinancialIncremental + COUNT(IF(j.ErrorType = 'P',j.ErrorType,0))
AS 'Financial Incremental'
FROM DemoScheme.TestTable j WHERE IsDeleted = 0 AND ErrorType IN ('P','NP')
GROUP BY ErrorCategory;

I"m trying to add a new col that shows the rank (or sequence) of row results by date.
I've written:
SELECT
#row_number:=(CASE
WHEN #member_id = lh.member_id and lc.ladder_advocacy is not null
THEN #row_number + 1
when #member_id = lh.member_id and lc.ladder_advocacy is null then "null"
ELSE 1 /* there is an error here - i need it to return a 1 if not null, then 2 for the 2nd instance, etc */
END) AS rank_advocacy,
#member_id:=lh.member_id AS member_id,
lh.ladder_change,
lc.name,
lc.ladder_advocacy,
lc.ladder_elected,
lc.ladder_policy,
lc.ladder_engagement,
lc.ladder_newventure,
lc.ladder_collective,
lc.is_trigger
FROM
leenk_ladder_history AS lh
LEFT JOIN
leeds_so.leenk_ladder_config AS lc ON lh.ladder_config_id = lc.id
WHERE
ladder_change = 1 AND trigger_active = 1
ORDER BY member_id, trigger_event_date DESC;
There is an error at row 4, and I'm not sure how to fix it. For the first result, I want to return 1. for the second results, I want to return #row_number + 1. Third result, #row_number+2 (etc).
How do I achieve this?
I don't understand how the condition lc.ladder_advocacy is not null is being used. However, the basic structure is:
SELECT (#row_number = IF(#member_id = lh.member_id, #row_number + 1
IF(#member_id := lh.member_id, 1, 1)
)
) as rank_advocacy,
lh.ladder_change,
. . .
Some really important points:
You need to assign #member_id and #row_number in the same expression. MySQL (as with all other databases) does not guarantee the order of evaluation of expressions.
In more recent versions of MySQL, I think the ORDER BY needs to go in a subquery, with the variable expressions in the outer query.
I have the following code written for a larger report that I have been working on. I have three columns resulting from subqueries: req_hrs, e_hrs, inprog_hrs. I need to add together the e_hrs and inprog_hrs, thus seeing whether that number is greater than or equal to req_hrs. If that is true, I need to return either an * or a null value.
Can someone please explain to me how I can add the two subquery results (e_hrs and inprog_hrs) together, and then compare that result to req_hrs thus returning said * or NVL? Code is below, Thank you:

Compare the sum of the union of the two sources with the required amount.
In simplified form:
select somekey, sum(hrs) worked_hrs, sum(req_hrs) required_hrs
from (
select
somekey,
e_hrs hrs
from e_hrs_table
where ...
union all -- the "all" is important to leave in!
select
somekey,
inprog_hrs
from inprog_hrs_table
where ...
) x
join req_hrs_table on req_hrs_table.somekey = x.somekey
where ... -- add req_hrs_table conditions here
group by somekey
You can add
having sum(hrs) < sum(req_hrs)
if you want only those rows that did not meet the quota.
Hello I have this query that i am trying to execute and i keep getting this error "Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.", Kindly help please.
DECLARE #NUMCOUNT BIT
Select #NUMCOUNT = (SELECT
CASE WHEN
(SELECT COUNT(R5REQUISLINES.RQL_REQ)
WHERE R5REQUISLINES.RQL_STATUS IN ('A')
) IN
(SELECT COUNT(R5REQUISLINES.RQL_REQ)
WHERE R5REQUISLINES.RQL_STATUS IN ( 'A','C') ) THEN 1 else 0 END AS NUMCOUNT1
FROM R5REQUISLINES JOIN
R5REQUISITIONS ON R5REQUISLINES.RQL_REQ = R5REQUISITIONS.REQ_CODE
GROUP BY R5REQUISLINES.RQL_REQ, R5REQUISITIONS.REQ_CODE,R5REQUISLINES.RQL_STATUS
)
IF #NUMCOUNT = '1'
begin
UPDATE R5REQUISITIONS
SET R5REQUISITIONS.REQ_STATUS = 'CP'
end
Ok, it sounds like what you actually want to do is update R5REQUISITIONS when there is no RQL_STATUS = 'C' in R5REQUISLINES, since you said you want to count the records where the RQL_STATUS is A and where it's A or C, and then do the update if the counts are the same.. You can greatly simplify this task with the following query:
UPDATE r5
SET r5.REQ_STATUS = 'CP'
FROM R5REQUISITIONS r5
WHERE NOT EXISTS (SELECT 1 FROM R5REQUISLINES r5q WHERE r5q.RQL_REQ = r5.REQ_CODE AND r5q.RQL_STATUS = 'C')
Your 'SELECT CASE' is returning more than 1 record, so it can't be assigned to #NUMBER. Either fix the sub-query to only return the record your looking for or hack it to return only 1 with a 'LIMIT 1' qualification.
I don't know what your data looks like so I can't tell you why your case subquery returns more records than you think it should.
Try running this and see what it returns, that will probably tell you wall you need to know:
SELECT
CASE WHEN
(SELECT COUNT(R5REQUISLINES.RQL_REQ)
WHERE R5REQUISLINES.RQL_STATUS IN ('A')
) IN
(SELECT COUNT(R5REQUISLINES.RQL_REQ)
WHERE R5REQUISLINES.RQL_STATUS IN ( 'A','C')
)
THEN 1
ELSE 0
END AS NUMCOUNT1
FROM R5REQUISLINES JOIN
R5REQUISITIONS ON R5REQUISLINES.RQL_REQ = R5REQUISITIONS.REQ_CODE
GROUP BY R5REQUISLINES.RQL_REQ, R5REQUISITIONS.REQ_CODE,R5REQUISLINES.RQL_STATUS
If there is more than 1 row returned, that's where your problem is.
table
create table tst(locationId int,
scheduleCount tinyint(1) DEFAULT 0,
displayFlag tinyint(1) DEFAULT 0);
INSERT INTO tst(locationId,scheduleCount)
values(5,0),(2,0),(5,1),(5,2),(2,1),(2,2);
I update multiple rows and multiple columns with one query, but want to change the one of the columns only for the first row and keep the other things the same for that column.
I want to update all the rows with some location id and change displayFlag to 1 and increment scheduleCount of only the top entry with 1 , rest would remain the same
**Query **
update tst,(select #rownum:=0) r,
set tst.displayFlag =1,
scheduleCount = (CASE WHEN #rownum=0
then scheduleCount+1
ELSE scheduleCount
END),
#rownum:=1 where locationId = 5
But it gives error and does not set the user defined variable rownum, I am able to join the tables in a select and change the value of the rownum, is there any other way to update the values.
I'm not sure this is the correct way of doing such a thing, but it is possible to include the user variable logic in the CASE condition:
UPDATE tst
JOIN (SELECT #first_row := 1) r
SET tst.displayFlag = 1,
scheduleCount = CASE
WHEN #first_row = 1 AND ((#first_row := 0) OR TRUE) THEN scheduleCount+1
ELSE scheduleCount
END
WHERE locationId = 5;
I have used a #first_row flag as this is more inline with your initial attempt.
The CASE works as follows:
On the first row #first_row = 1 so the second part of the WHEN after AND is processed, setting #first_row := 0. Unfortunately for us, the assignment returns 0, hence the OR TRUE to ensure the condition as a whole is TRUE. Thus scheduleCount + 1 is used.
On the second row #first_row != 1 so the condition is FALSE, the second part of the WHEN after AND is not processed and the ELSE scheduleCount is used.
You can see it working in this SQL Fiddle. Note; I have had to set the column types to TINYINT(3) to get the correct results.
N.B. Without an ORDER BY there is no guarantee as to what the '1st' row will be; not even that it will be the 1st as returned by a SELECT * FROM tst.
UPDATE
Unfortunately one cannot add an ORDER BY if there is a join.. so you have a choice:
Initialise #first_row outside the query and remove the JOIN.
Otherwise you are probably better off rewriting the query to something similar to:
UPDATE tst
JOIN (
SELECT locationId,
scheduleCount,
displayFlag,
#row_number := #row_number + 1 AS row_number
FROM tst
JOIN (SELECT #row_number := 0) init
WHERE locationId = 5
ORDER BY scheduleCount DESC
) tst2
ON tst2.locationId = tst.locationId
AND tst2.scheduleCount = tst.scheduleCount
AND tst2.displayFlag = tst.displayFlag
SET tst.displayFlag = 1,
tst.scheduleCount = CASE
WHEN tst2.row_number = 1 THEN tst.scheduleCount+1
ELSE tst.scheduleCount
END;
Or write two queries:
UPDATE tst
SET displayFlag = 1
WHERE locationId = 5;
UPDATE tst
SET scheduleCount = scheduleCount + 1
WHERE locationId = 5
ORDER BY scheduleCount DESC
LIMIT 1;
I am using function to update to one column , like
DetailedStatus = dbo.fn_GetProcessStageWiseStatus(PR.ProcessID, PR.ProcessRunID, getdate())
Here 500,000 records are continuously UPDATED in this line. Its like like a loop
So using this function for few records its executing fast but when its 500,000 records executing it becomes very slow...
What can I do to make this execute faster using many records?
Any measures to be taken or any split to be used?

Thanks in advance.
Seems like you have a change in execution plan when you try to update 500k rows.
You can try and set forceseek hint on the from clause to force using seeks instead of scans.
Also, WHILE (#iRowCount > #iLoopCount) should be replaced with if exists, because you basically check for certain conditions on the results table and you need to return as early as possible.
I see that you use nolock hint everywhere to allow dirty reads, you can set isolation level read uncommitted in the calling stored procedure and remove all of those; or consider to change the database to set read_committed_snapshot on to avoid locks.
By the way, scalar function calls in SQL Server are very expensive, so if you have some massive updates/selects happening in a loop where you call a function you have to avoid using functions as much as possible.
