I have case entity in that I need to get how many cases created in last 7 days and closed in last 7 days. this I need to show it on chart every day for last 7days how many closed and created.
Can some one help on this. I have written SQL query to fetch but it is not working or should I have to go for expression?
This will produce the last 7 days even if there is no data by using a calendar table.

I suspect that the below part might be slowing it up. Can someone advise what can be done here?

Even though Visual Explain (VE) doesn't advise any indexes ... it can still be used to see how long various parts of your query are taking.
If the
SELECT
SOORD STOPORDER
, COUNT(*) STOPSREMAIN
, MIN(SOSTP#) NEXTSTOP
, MAX(SOAPPR) APPTREQ
Turns out to really be any issue, I'd look at using an Encoded Vector Index (EVI) with aggregate values to speed that up.
I'd suggest breaking it down and building back up while using VE to see where the issues lie.
The only magic wand I might suggest is putting code into a user defined table function (UDTF); assuming you currently plan to use the view like so:
select *
from myview
where something = 'somevalue';
A UDTF would allow for you to explicitly push the selection into the query
select *
from table ( myudtf('somevalue'));

I have a table called tbl_points with the following columns:
[key] identity
[fkey] int -> forign key from other table
[points] int -> number
[inputdate] datetime -> getdate()
And values like:
key,fkey,points,inputdate
1,23,5,20170731
2,23,2,20170801
3,23,4,20170801
4,25,2,20170801
5,25,2,20170802
6,23,5,20170803
7,25,3,20170803
8,23,5,20170804
I am executing a query like this:
select fkey,sum(points) points,month(inputdate) mnd,year(inputdate) yy
from tbl_points
group by fkey,month(inputdate) mnd,year(inputdate)
order by year(inputdate),month(inputdate) mnd,points
Which gives as result:
fkey,points,mnd,yy
23,14,8,2017
25,7,8,2017
25,5,7,2017
So far so good. Now I want only the top 1 of each month, so
23,14,8,2017
25,5,7,2017
I can do this in the code, or in the stored procedure with a temporary table or cursor.
But perhaps there is is simpler solution. Any ideas? Or a better approach?
DECLARE #tbl_points TABLE
(
[key] INT ,
[fkey] INT ,
[points] INT ,
[inputdate] DATETIME
);
INSERT INTO #tbl_points

/* Your query */
SELECT fkey ,
SUM(points) points ,
YEAR(inputdate) [year] ,
MONTH(inputdate) [month]
FROM #tbl_points
GROUP BY fkey ,

ORDER BY YEAR(inputdate) ,

/* Query you want */
SELECT s.fkey ,
s.points ,

s.[month]
FROM ( SELECT fkey ,
SUM(points) points ,

Result:
I have a table which has 3 columns: Product, Date, Status
I want to rank in this manner:
for each product order by Date, and Rank if Status = FALSE then 0, if it's TRUE then start ranking by 1, continue ranking by the same value if previous Status is TRUE.
In this ordered set if FALSE comes assign to it 0, and for the next coming TRUE status for same product assign x+1 (x here is previous rank value for status TRUE).
I hope picture makes it more clear
This code uses SS2008R2 features which do not include LEAD/LAG. A better solution is certainly possible with more modern versions of SQL Server.

Note that the sample data was extracted from an image using a Mark I Eyeball. Had the OP taken heed of advice here it would have been somewhat easier.
Tip: Using column names that don't happen to match data types and keywords makes life somewhat simpler.
Try this query,
SELECT a.Product ,
a.Date ,
a.Status ,
CASE WHEN a.Status = 'FALSE' THEN 0
ELSE 1
END [Rank]
FROM ( SELECT Product ,
Date ,
Status ,
ROW_NUMBER() OVER ( PARTITION BY Product ORDER BY DATE, Status ) RNK
FROM TableProduct
) a
ORDER BY Product, a.RNK
I need a example of a cursor for my meter system, where the system reads the meter every month.
The cursor needs to check, that every meter has a reading registered in the current year. For meters with missing readings, an estimated value is added, such that the daily consumption is like the daily comsumption in the previous period plus 15%. In no previous period exiss, the above Kwh value is used.
How about something like this. (The MonthSeed table could become a real table in your database)
declare #MonthSeed table (MonthNumber int)
insert into #MonthSeed values (1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12)
-- assumes declared table "Reading" with fields ( Id int, [Date] datetime, MeterNo varchar(50), Consumption int )
select
m.MeterNo,
r.Date,
calculatedConsumption = isnull(r.Consumption, -- read consumption
isnull((select max(r2.Consumption) Consumption from Reading r2 where datepart(month, r2.Date) = (m.MonthNumber - 1) and r2.MeterNo = m.MeterNo) * 1.15, -- previous consumption + 15%
9999)) -- default consumption
from
(select distinct
MeterNo,
MonthNumber
from
Reading, #MonthSeed) m
left join
Reading r on r.MeterNo = m.MeterNo and datepart(month, r.Date) = m.monthNumber
EDIT FOLLOWING COMMENTS - EXAMPLE OF ADDING MISSING READINGS
As commented need to include an insert before the select insert into Reading (MeterNo, Date, Consumption) and making use of the left join to the reading table include a check for the reading id to be null ie missing where r.Id is null.
I noticed that this would result in null date entries when inserting into the reading table. So I included a date aggregate in the main sub-select Date = dateadd(month, monthnumber, #seeddate); the main select was amended to show a date for missing entries isnull(r.Date, m.Date),
I've calculated the #SeedDate to be the 1st of the current month one year ago but you may want to pass in an earlier date.
declare #MonthSeed table (MonthNumber int)
insert into #MonthSeed values (1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12)
-- assumes declared table "Reading" with fields ( Id int, [Date] datetime, MeterNo varchar(50), Consumption int )
declare #SeedDate datetime = (select dateadd(month, datediff(month, 0, getdate())-12, 0)) -- this month, last year
insert into Reading (MeterNo, Date, Consumption)
select
m.MeterNo,
isnull(r.Date, m.Date),
calculatedConsumption =
isnull(r.Consumption, -- read consumption
isnull(1.15 * (select max(r2.Consumption) Consumption
from Reading r2
where datepart(month, r2.Date) = (m.MonthNumber - 1)
and r2.MeterNo = m.MeterNo), -- previous consumption + 15%
9999)) -- default consumption
