Based on current date, I need to set case in WHERE condition.
select
count(id)
from
table1
case
when (DAY(GETDATE())) between 1 and 15
Then created_date between (getdate()-DAY(GETDATE())+1) and (getdate()+15-DAY(GETDATE()))
else created_date between (getdate()+16-DAY(GETDATE())) and (getdate()+31-DAY(GETDATE()))
End
but it does not work for me.
For eg,
Table1:
Id App_Name Created_Date
1 app1 2016-12-05
2 app2 2016-12-10
3 app3 2016-12-16
4 app4 2016-12-25
5 app5 2016-12-28
Today date is 2016-12-15, So i need to take created_date between 2016-12-01 to 2016-12-15.
Expected output is "2"
You can try using a nested CASE expression along with conditional aggregation:
SELECT CASE WHEN DAY(GETDATE()) <= 15 THEN
SUM(CASE WHEN created_date BETWEEN (getdate()-DAY(GETDATE())+1) AND
(getdate()+15-DAY(GETDATE()))
THEN 1 ELSE 0 END)
ELSE
SUM(CASE WHEN created_date BETWEEN (getdate()+16-DAY(GETDATE())) AND
(getdate()+31-DAY(GETDATE()))
THEN 1 ELSE 0 END)
END AS summary
FROM table1
The simple way of doing it.Working perfectly.Try it once
SELECT CASE
WHEN (DAY(GETDATE())) < 16 THEN
(Select Count(1) from SEP_RetailStore WITH (NOLOCK) WHERE DAY(CreateDate) BETWEEN 1 and 15)
ELSE (Select Count(1) from SEP_RetailStore WITH (NOLOCK) WHERE DAY(CreateDate) >= 16)
END

I have a table in SQL Server:
CREATE TABLE healthRegistration
(
ID uniqueidentifier PRIMARY KEY,
RegisterDateTime DateTime NOT NULL,
RUFeelingWell Bool NOT NULL
);
The RegisterDateTime is the date and time that the user created the register and RUFeelingWell is a boolean value.
I want to create a query that returns 3 columns: Register Date, Count of entries with RUFeelingWell = False on that date, Count of entries with RUFeelingWell = True on that date
How can I do this?
SELECT CAST(T.RegisterDateTime AS DATE)REGISTERDATE,
SUM
(
CASE
WHEN T.RUFeelingWell =1 THEN 1
ELSE 0
END
)AS TRUE_RECORDS,
SUM
( CASE
WHEN T.RUFeelingWell =0 THEN 1
ELSE 0
END
)AS FALSE_RECORDS
FROM healthRegistration AS T
GROUP BY CAST(T.RegisterDateTime AS DATE)
Try this query:
Select
Convert(char(8), RegisterDateTime, 112),
Sum(Case RUFeelingWell When 1 Then 1 Else 0 End) As wellnos,
Sum(Case RUFeelingWell When 0 Then 1 Else 0 End) As notwellnos
From healthRegistration
Group By Convert(char(8), RegisterDateTime, 112)
Order By Convert(char(8), RegisterDateTime, 112)
Here Convert(char(8), RegisterDateTime, 112) gives date in YYYYMMDD format so that entries for a day are summed together.
Boolean values are stored as 1 and 0 in the database
We have been keeping track of some changes in a History Table like this:
ChangeID EmployeeID PropertyName OldValue NewValue ModifiedDate
100 10 EmploymentStart Not Set 1 2013-01-01
101 10 SalaryValue Not Set 55000 2013-01-01
102 10 SalaryValue 55000 61500 2013-03-20
103 10 SalaryEffectiveDate 2013-01-01 2013-04-01 2013-03-20
104 11 EmploymentStart Not Set 1 2013-01-21
105 11 SalaryValue Not Set 43000 2013-01-21
106 10 SalaryValue 61500 72500 2013-09-20
107 10 SalaryEffectiveDate 2013-04-01 2013-10-01 2013-09-20
Basically if an Employee's Salary changes, we log two rows in the history table. One row for the Salary value itself and the other row for the salary effective date. So these two have identical Modification Date/Time and are kind safe to assume that are always after each other in the database. We can also assume that Salary Value is always logged first (so it is one record before the corresponding effective date
Now we are looking into creating reports based on a given date range into a table like this:
Annual Salary Change Report (2013)
EmployeeID Date1 Date2 Salary
10 2013-01-01 2013-04-01 55000
10 2013-04-01 2013-10-01 61500
10 2013-10-01 2013-12-31 72500
11 2013-03-21 2013-12-31 43000
I have done something similar in the past by joining the table to itself but in those cases the effective date and the new value where in the same row. Now I have to create each row of the output table by looking into a few rows of the existing history table. Is there an straightforward way of doing this whitout using cursors?
Edit #1:
Im reading on this and apparently its doable using PIVOTs
Thank you very much in advance.
You can use self join to get the result you want. The trick is to create a cte and add two rows for each EmployeeID as follows (I call the history table ht):
with cte1 as
(
select EmployeeID, PropertyName, OldValue, NewValue, ModifiedDate
from ht
union all
select t1.EmployeeID,
(case when t1.PropertyName = "EmploymentStart" then "SalaryEffectiveDate" else t1.PropertyName end),
(case when t1.PropertyName = "EmploymentStart" then t1.ModifiedDate else t1.NewValue end),
(case when t1.PropertyName = "SalaryValue" then t1.NewValue
when t1.PropertyName = "SalaryEffectiveDate" then "2013-12-31"
when t1.PropertyName = "EmploymentStart" then "2013-12-31" end),
"2013-12-31"
from ht t1
where t1.ModifiedDate = (select max(t2.ModifiedDate) from ht t2 where t1.EmployeeID = t2.EmployeeID)
)
select t3.EmployeeID, t4.OldValue Date1, t4.NewValue Date2, t3.OldValue Salary
from cte1 t3
inner join cte1 t4 on t3.EmployeeID = t4.EmployeeID
and t3.ModifiedDate = t4.ModifiedDate
where t3.PropertyName = "SalaryValue"
and t4.PropertyName = "SalaryEffectiveDate"
order by t3.EmployeeID, Date1
I hope this helps.
It is a little over kill to use pivot since you only need two properties. Use GROUP BY can also achieve this:
;WITH cte_salary_history(EmployeeID,SalaryEffectiveDate,SalaryValue)
AS
(
SELECT EmployeeID,
MAX(CASE WHEN PropertyName='SalaryEffectiveDate' THEN NewValue ELSE NULL END) AS SalaryEffectiveDate,
MAX(CASE WHEN PropertyName='SalaryValue' THEN NewValue ELSE NULL END) AS SalaryValue
FROM yourtable
GROUP BY EmployeeID,ModifiedDate
)
SELECT EmployeeID,SalaryEffectiveDate,
LEAD(SalaryEffectiveDate,1,'9999-12-31') OVER(PARTITION BY EmployeeID ORDER BY SalaryEffectiveDate) AS SalaryEndDate,
SalaryValue
FROM cte_salary_history
I'm struggling to find an effective, concise way without a loop to produce groups of active dates where activity (grant/rescind activity) is based on the Switch column which has values 0 off and 1 on and start and end dates.
TransactionDate EffectiveDate TerminationDate Switch
-------------------------------------------------------------------
2013-06-14 2013-05-29 NULL 1
2013-06-14 2013-06-05 2013-06-05 0
2013-10-03 2013-05-29 2013-05-29 0
2013-10-12 2013-05-29 NULL 1
2013-10-12 2013-06-06 2013-06-06 0
The final output should be but one row:
2013-05-29 to 2013-06-06
The output is one row because the the last two transactions were switch on for 5/29/2013 and the last switch off was for 2013-06-06, which becomes the end date for the span.
Even more, the dates should also be grouped by active spans. If there were another year record in here it would need to be on a separate row.
Can I please get some help with a query to solve this issue?
Is this what you want?
select max(case when switch = 1 then effective_date end) as on_date,
(case when max(case when switch = 1 then effective_date end) <
max(case when switch = 0 then effective_date end)
then max(case when switch = 0 then effective_date end)
end) as off_date -- if any
from t;
This gets the last date the switch is on. And then the last date after that it is off.
Let's start with a sample of the data I'm working with:
Policy No | start date
1 | 2/15/2006
1 | 2/15/2009
1 | 2/15/2012
2 | 3/15/2006
3 | 3/19/2006
3 | 3/19/2012
4 | 3/31/2006
4 | 3/31/2009
I'm trying to write code in SQL Server 2008 that counts a few things. The principle is that the policyholder's earliest start date is when the policy began. Every three years an increase is offered to the client. If they agree to the increase, the start date is refreshed with the same date as the original, three years later. If they decline, nothing is added to the database at all.
I'm trying to not only count the number of times a customer accepted the offer (or increased the start date by three years), but separate it out by first offer or second offer. Taking the original start date and dividing the number of days between now and then by 1095 gets me the total number of offers, so I've gotten that far. What I really want it to do is compare each policy number to the one before it to see if it's the same (it's already ordered by policy number), then count the date change in a new "accepted" column and count the times it didn't change but could have as "declined".
Is this a case where I would need to self-join the table to itself to compare the dates? Or is there an easier way?
are you looking for this :-
Set Nocount On;
Declare #Test Table
(
PolicyNo Int
,StartDate Date
)
Declare #PolicyWithInc Table
(
RowId Int Identity(1,1) Primary Key
,PolicyNo Int
,StartDate Date
)
Insert Into #Test(PolicyNo,StartDate) Values
(1,'2/15/2006')
,(1,'2/15/2009')
,(1,'2/15/2012')
,(2,'3/15/2006')
,(3,'3/19/2006')
,(3,'3/19/2012')
,(4,'3/31/2006')
,(4,'3/31/2009')
Insert Into #PolicyWithInc(PolicyNo,StartDate)
Select t.PolicyNo
,t.StartDate
From #Test As t
Select pw.PolicyNo
,Sum(Case When Datediff(Year,t.StartDate, pw.StartDate) = 3 Then 1 Else 0 End) As DateArrived
,Sum(Case When Datediff(Year,t.StartDate, pw.StartDate) > 3 Then 1 Else 0 End) As DateNotArrived
,Sum(Case When Isnull(Datediff(Year,t.StartDate,pw.StartDate),0) = 3 Then 1 Else 0 End) As Years3IncrementCount
From #PolicyWithInc As pw
Left Join #PolicyWithInc As t On pw.PolicyNo = t.PolicyNo And pw.RowId = (t.RowId + 1)
Group By pw.PolicyNo
Probably below could help:

I have a query in MS SQL Server asking for name and some date-related information, depending on two dates, a start- and an enddate.
The problem is, I´m not always getting the same performance. Whenever I request something between the dates;
2010-07-01 00:00:00.000 and
2011-07-21 23:59:59.999
the performance is excellent. I get my result within mseconds. When I request something between these dates, for example,
2011-07-01 00:00:00.000 and
2011-07-21 23:59:59.999
the performance is.. less than good, taking between 20-28 seconds for each query. Do note how the dates giving good performance is more than a year between, while the latter is 20 days.
Is there any particular reason (maybe related to how DATETIME work) for this?
EDIT: The query,
SELECT ENAME,
SUM(CASE DATE WHEN 0 THEN 1 ELSE 0 END) AS U2,
SUM(CASE DATE WHEN 1 THEN 1 ELSE 0 END) AS B_2_4,

(parts of) The tables:

-date (case created at this date)

-Date (can be multiple, MAX(status.date) gives us date when
status was last changed)
I would have thought a statistics issue.
When you are only selecting the most recent dates these may be unrepresented in the statistics yet as the threshold has not yet been reached that would trigger auto updating.
See this blog post for an example.
