I have this query :
Declare #t table ( StartDate datetime , ENDDate datetime)
Insert into #t values ('2020-02-05 15:00:00.000','2020-02-05 15:30:00.000')
Insert into #t values ('2020-02-05 15:10:00.000','2020-02-05 15:20:00.000')
Declare #time datetime ='2020-02-05 15:11:00.000'
select top 1 * from #t
where StartDate <= #time
order by StartDate desc
It gives me 2nd row as an output which is correct. Because time is 15:11:00.000.
Now If I pass
Declare #time datetime ='2020-02-05 15:31:00.000'
And I run the above query it still gives me the same output, But I want to show the 1st row as an output. What changes do I need to make to satisfy both the requirement with 1 query?
The reason I want to show the 1st row as an output: Because the enddate which is being passed is near to the end date of the 1st row, I can write the second query to fetch the data, But I need just 1 query wherin both the condition should be satisfied.
I tried this as well:
Declare #t table ( StartDate datetime , ENDDate datetime)
Insert into #t values ('2020-02-05 15:00:00.000','2020-02-05 15:30:00.000')
Insert into #t values ('2020-02-05 15:10:00.000','2020-02-05 15:20:00.000')
Declare #time datetime ='2020-02-05 15:11:00.000'
select *,DATEDIFF(MINUTE,ENDDate,#time) DTB from (
select top 1 * from #t
where StartDate <= #time
order by StartDate desc
) a
order by dtb
But I am still getting the same output.
Can you please try this below logic-
DEMO HERE
Declare #t table ( StartDate datetime , ENDDate datetime)
Insert into #t values ('2020-02-05 15:00:00.000','2020-02-05 15:30:00.000')
Insert into #t values ('2020-02-05 15:10:00.000','2020-02-05 15:20:00.000')
--Declare #time datetime ='2020-02-05 15:11:00.000'
Declare #time datetime ='2020-02-05 15:31:00.000'
select TOP 1 *
from #t
where StartDate <= #time
ORDER BY ABS(datediff(mi,ENDDate,#time))
** Your query only checking one condition StartDate <= #time, if you wanted to fetch the 1st record from your table which matches the condition then remove desc from your query.
select top 1 * from #t
where StartDate <= #time
order by StartDate
** if you want to sort the date and fetch based on date difference between StartDate and passing date #t the use DATEDIFF
select *,DATEDIFF(MINUTE, StartDate, #time) as dif from #t
where cast(StartDate as datetime) <= cast(#time as datetime)
ORDER BY DATEDIFF(MINUTE, StartDate, #time)
select top 1 * from #t
where cast(StartDate as datetime) <= cast(#time as datetime)
ORDER BY DATEDIFF(MINUTE, StartDate, #time)

I want to show all dates between two dates when there is any date data missing then its should show zero in val column .
declare #temp table (
id int identity(1,1) not null,
CDate smalldatetime ,
val int
)
INSERT STATEMENT FOR DATA TO CHECK
insert into #temp select '10/2/2012',1
insert into #temp select '10/3/2012',1
insert into #temp select '10/5/2012',1
insert into #temp select '10/7/2012',2
insert into #temp select '10/9/2012',2
insert into #temp select '10/10/2012',2
insert into #temp select '10/13/2012',2
insert into #temp select '10/15/2012',2
Retrieve records between first day of month and today
select * from #temp where CDate between '10/01/2012' AND '10/15/2012'
As i run this query its show me all data between these two dates but i want to also include missing dates with val=0
SQL FIDDLE WITH SAMPLE DATA
;with d(date) as (
select cast('10/01/2012' as datetime)
union all
select date+1
from d
where date < '10/15/2012'
)
select t.ID, d.date CDate, isnull(t.val, 0) val
from d
left join temp t
on t.CDate = d.date
order by d.date
OPTION (MAXRECURSION 0) -- use this if your dates are >99 days apart
You need to make up the dates, so I've use a recursive common table expression here.
SQL Fiddle
MAXRECURSION number
Specifies the maximum number of recursions allowed for this query. number is a nonnegative
integer between 0 and 32767. When 0 is specified, no limit is applied. If this option is
not specified, the default limit for the server is 100.
When the specified or default number for MAXRECURSION limit is reached during query
execution, the query is ended and an error is returned.
This will work as long as there are less than 2047 days between from and to dates
declare #from smalldatetime = '10/01/2012'
declare #to smalldatetime = '10/15/2012'
select t.id, dateadd(day, number,#from), isnull(val, 0) val from #temp t
right join master..spt_values s
on dateadd(d, s.number, #from) = t.CDate
where
datediff(day, #from, #to ) > s.number
and s.type = 'P'
I think the best way to do this is to create your own table with dates (you can also use master.dbo.spt_values, but I personally don't like that solution)
declare #Temp_Dates table (CDate datetime)
declare #Date datetime
select #Date = (select min(CDate) from temp)
while #Date <= (select max(CDate) from temp)
begin
insert into #Temp_Dates (CDate)
select #Date
select #Date = dateadd(dd, 1, #Date)
end
select D.CDate, isnull(T.id, 0) as id
from #Temp_Dates as D
left outer join temp as T on T.CDate = D.CDate
you can also use recursive solution with CTE
DECLARE #min DATETIME,
#max DATETIME,
#val INT
SELECT #min = Min(CDATE),
#max = Max(CDATE)
FROM TEMP
DECLARE #temp TABLE
(
CDATE SMALLDATETIME,
VAL INT
)
WHILE #min < #max
BEGIN
SELECT #val = VAL
FROM TEMP
WHERE CDATE = #min
INSERT #temp
VALUES (#min,
#val)
SET #min = Dateadd(D, 1, #min)
SET #val = 0
END
SELECT *

insert into #temp select '10/10/2012',2
insert into #temp select '10/13/2012',2
insert into #temp select '10/15/2012',2
DECLARE #startDate DATE= '10/01/2012'
DECLARE #endDate DATE= '10/15/2012'
SELECT t.Id, X.[Date],Val = COALESCE(t.val,0)
FROM
(SELECT [Date] = DATEADD(Day,Number,#startDate)
FROM master..spt_values
WHERE Type='P'
AND DATEADD(day,Number,#startDate) <= #endDate)X
LEFT JOIN #temp t
ON X.[Date] = t.CDate
using a recursive cte with min and max
declare #T table (id int identity(1,1) primary key, dt date not null, val int not null);

I have start date, end date and name of days. How can fetch all dates between those two dates of that specific days in sql?
example data:
start_date:4/11/2018
end_date: 5/11/2018
days: monday, thursday
expected output: all dates between start and end date which comes on monday and thursday and store them in table
updated
my present code(not working)
; WITH CTE(dt)
AS
(
SELECT #P_FROM_DATE
UNION ALL
SELECT DATEADD(dw, 1, dt) FROM CTE
WHERE dt < #P_TO_DATE
)
INSERT INTO Table_name
(
ID
,DATE_TIME
,STATUS
,CREATED_DATE
,CREATED_BY
)
SELECT #P_ID
,(SELECT dt FROM CTE WHERE DATENAME(dw, dt) In ('tuesday','friday',null))
,'NOT SENT'
,CAST(GETDATE() AS DATE)
,#USER_ID
Another approach for generating dates between ranges can be like following query. This will be faster compared to CTE or WHILE loop.
DECLARE #StartDate DATETIME = '2018-04-11'
DECLARE #EndDate DATETIME = '2018-05-15'
SELECT #StartDate + RN AS DATE FROM
(
SELECT (ROW_NUMBER() OVER (ORDER BY (SELECT NULL)))-1 RN
FROM master..[spt_values] T1
) T
WHERE RN <= DATEDIFF(DAY,#StartDate,#EndDate)
AND DATENAME(dw,#StartDate + RN) IN('Monday','Thursday')
Note:
If the row count present in master..[spt_values] is not sufficient for the provided range, you can make a cross join with the same to get a bigger range like following.
SELECT (ROW_NUMBER() OVER (ORDER BY (SELECT NULL)))-1 RN
FROM master..[spt_values] T1
CROSS JOIN master..[spt_values] T2
By this you will be able to generate date between a range with gap of 6436369 days.
You can use a recursive common table expression (CTE) to generate a list of days. With datepart(dw, ...) you can filter for specific days of the week.
An example that creates a list of Mondays and Thursdays between March 1st and today:
create table ListOfDates (dt date);
with cte as
(
select cast('2018-03-01' as date) as dt -- First day of interval
union all
select dateadd(day, 1, dt)
from cte
where dt < getdate() -- Last day of interval
)
insert into ListOfDates
(dt)
select dt
from cte
where datepart(dw, dt) in (2, 5) -- 2=Monday and 5=Thursday
option (maxrecursion 0)
See it working at SQL Fiddle.
This will work for you:
DECLARE #table TABLE(
ID INT IDENTITY(1,1),
Date DATETIME,
Day VARCHAR(50)
)
DECLARE #Days TABLE(
ID INT IDENTITY(1,1),
Day VARCHAR(50)
)
INSERT INTO #Days VALUES ('Monday')
INSERT INTO #Days VALUES ('Thursday')
DECLARE #StartDate DATETIME='2018-01-01';
DECLARE #EndDate DATETIME=GETDATE();
DECLARE #Day VARCHAR(50)='Friday';
DECLARE #TempDate DATETIME=#StartDate;
WHILE CAST(#TempDate AS DATE)<=CAST(#EndDate AS DATE)
BEGIN
IF EXISTS (SELECT 1 FROM #Days WHERE DAY IN (DATENAME(dw,#TempDate)))
BEGIN
INSERT INTO #table
VALUES (
#TempDate, -- Date - datetime
DATENAME(dw,#TempDate) -- Day - varchar(50)
)
END
SET #TempDate=DATEADD(DAY,1,#TempDate)
END
SELECT * FROM #table
INSERT INTO TargetTab(dateCOL)
SELECT dateCOL
FROM tab
WHERE dateCOL >= startdate AND dateCOL <= enddate
AND (DATENAME(dw,dateCOL) ='Thursday' OR DATENAME(dw,dateCOL) = 'Monday')
Try this query to get your result.
Use a recursive CTE to generate your dates, then filter by week day.
SET DATEFIRST 1 -- 1: Monday, 7 Sunday
DECLARE #StartDate DATE = '2018-04-11'
DECLARE #EndDate DATE = '2018-05-15'
DECLARE #WeekDays TABLE (WeekDayNumber INT)
INSERT INTO #WeekDays (
WeekDayNumber)
VALUES
(1), -- Monday
(4) -- Thursday
;WITH GeneratingDates AS
(
SELECT
GeneratedDate = #StartDate,
WeekDay = DATEPART(WEEKDAY, #StartDate)
UNION ALL
SELECT
GeneratedDate = DATEADD(DAY, 1, G.GeneratedDate),
WeekDay = DATEPART(WEEKDAY, DATEADD(DAY, 1, G.GeneratedDate))
FROM
GeneratingDates AS G -- Notice that we are referencing a CTE that we are also declaring
WHERE
G.GeneratedDate < #EndDate
)
SELECT
G.GeneratedDate

GeneratingDates AS G
INNER JOIN #WeekDays AS W ON G.WeekDay = W.WeekDayNumber
OPTION

Try this:
declare #start date = '04-11-2018'
declare #end date = '05-11-2018'

I have an SQL Statement which accepts a parameter #EndDate as DateTime. I want to be able to pass several values for #EndDate one by one and then Union the results of all the Queries. I have tried using CTE for this but it is of no use. I want to pass several Dates for #EndDate. Any help would be greatly appreciated.
My Query is:
DECLARE #EndDate as DateTime
SET #EndDate = '2018/02/25'
SELECT
CONVERT(VARCHAR, #EndDate, 101) [R_Date]
,[Name]
[Type]
FROM [dbo].[S_Table]
This is Sample query how u can loop through multiple dates. A while loop should select all rows into one table, do not need to perform union all
DECLARE #table TABLE (
day INT
,Month INT
,DATE DATE
)
DECLARE #startdate DATE = '2018/02/25'
DECLARE #enddate DATE = cast(getdate() AS DATE)
WHILE #startdate <= #enddate
BEGIN
SELECT #startdate = dateadd(dd, 1, #startdate)
INSERT #table (
day
,Month
,DATE
)
SELECT day(#startdate)
,MONTH(#startdate)
,#startdate
END
SELECT *
FROM #table;
In your logic for passing multiple values into query , you can store result set into temporal table, which holds looped records
DECLARE #table TABLE (
[R_Date] DATE
,Name VARCHAR(155)
,Value VARCHAR(155)
)
DECLARE #enddate DATE = '2018/02/25'
DECLARE #enddate1 DATE = cast(getdate() AS DATE)
WHILE #enddate <= #enddate1
BEGIN
SELECT #enddate = dateadd(dd, 1, #enddate)
INSERT #table (
R_Date
,Name
,Value
)
SELECT CONVERT(VARCHAR, #EndDate, 101) [R_Date]
,[Name] [Type]
FROM [dbo].[S_Table]
WHERE DATE = #enddate
-------More filters
END
SELECT *
FROM #table;
I currently have a table with a creation date and a expiry date. I currently have a sql command to get the number of valid items for a given date.
select
count(id) ,CONVERT(date, getdate())
from
table
where
createDate < getdate() and expDate > getdate()
This returns the count and current date.
Is it possible to wrote a sql query that will return the result for a range of dates, say I if wanted to plot the number of valid items over a range of 15 days?
Thanks!
Try this:
create table #datelist (ValidDateCheck date, ValidResults int)
declare #startdate date = '1/1/2015'
declare #enddate date = '2/1/2015'
declare #interval int = 1 --Use 1 if you want every day between your dates, use 2 if you want every other day, etc.
declare #datecounter date = #startdate
declare #count int
while #datecounter <= #enddate
begin
set #count =
(select count(*)
from Table
where CrtDt <= #datecounter and ExpDt > #datecounter)
insert into #datelist values (#datecounter, #count)
set #datecounter = dateadd(dd, #interval, #datecounter)
end
select * from #datelist order by 1
It loops through all the dates in your range, counting valid results for each one.
Check this,
DECLARE #StartDate DATETIME,
#EndDate DATETIME;
SELECT #StartDate = '20110501'
,#EndDate = '20110801';
SELECT
DATEADD(d, x.number, #StartDate) AS MonthName1
,
x.number
FROM master.dbo.spt_values x
WHERE x.type = 'P'
AND x.number <= DATEDIFF(MONTH, #StartDate, #EndDate);
The above query give the list of dates between 2 dates.
As per your table and question, check this also.
declare #table table(id int,frdt datetime, todt datetime)
insert into #table values (1,GETDATE()-20, GETDATE()-19)
,(2,GETDATE()-9, GETDATE()-8)
,(3,GETDATE()+20, GETDATE()+18)
,(4,GETDATE(), GETDATE()-1)
,(5,GETDATE()-20, GETDATE())
,(6,GETDATE()-10, GETDATE()+10 )
select * from #table
declare #frdt datetime = null , #todt datetime = getdate()-10
select #frdt, #todt,* from #table
where
(#frdt is null or #frdt between frdt and todt)
and
(#todt is null or #todt between frdt and todt)
select #frdt = GETDATE()-15 , #todt = GETDATE()

MAXRECURSION number
Specifies the maximum number of recursions allowed for this query. number is a nonnegative
integer between 0 and 32767. When 0 is specified, no limit is applied. If this option is
not specified, the default limit for the server is 100.
When the specified or default number for MAXRECURSION limit is reached during query
execution, the query is ended and an error is returned.
This will work as long as there are less than 2047 days between from and to dates
declare #from smalldatetime = '10/01/2012'

and s.type = 'P'
I think the best way to do this is to create your own table with dates (you can also use master.dbo.spt_values, but I personally don't like that solution)
declare #Temp_Dates table (CDate datetime)

end
select D.CDate, isnull(T.id, 0) as id
from #Temp_Dates as D
left outer join temp as T on T.CDate = D.CDate
you can also use recursive solution with CTE
