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;

In SQL, I am going to write a query which insert all data between 2 dates and also I want to bring then in a 1000 batch but since the number of data between those days are more than my limitation I was going to write a loop which makes the smaller period to bring the data.
here is my code:
DECLARE #StartDate DATETIME = CAST('2021-06-02 01:00:00.000' AS DATETIME)
DECLARE #EndDate DATETIME = CAST('2021-06-23 01:00:00.000' AS DATETIME)
DECLARE #RealRowCount INT = (SELECT DISTINCT SUM(##ROWCOUNT) OVER() FROM GetReport (
#StartDate, #EndDate))
DECLARE #TransactionCount INT = (SELECT DISTINCT TransactionCount FROM GetReport (
#StartDate, #EndDate))
WHILE #RealRowCount < #TransactionCount
BEGIN
DECLARE #DiffDate INT = (SELECT DATEDIFF(DAY, #StartDate, #EndDate))
SET #EndDate = DATEADD(DAY, #DiffDate/2 ,#StartDate)
SELECT *,#StartDate, #EndDate FROM GetReport (#StartDate, #EndDate)
END
PS: I was thinking about find the middle of the period of date and then change them into the new EneDate and StartDate but there is problem here!
Your question is not very clear. Suppose you have 10,000 records between two dates and you do not want to retrieve more than a thousand records at a time. In this case, you can use pagination. Both in the program code and in SQL.
DECLARE #StartDate DATETIME = CAST('2021-06-02 01:00:00.000' AS DATETIME)
DECLARE #EndDate DATETIME = CAST('2021-06-23 01:00:00.000' AS DATETIME)
DECLARE #RealRowCount INT = (SELECT DISTINCT COUNT(*) FROM Products WHERE InsertDate BETWEEN #StartDate AND #EndDate)
DECLARE #Counter INT = 0
WHILE #Counter <= #RealRowCount
BEGIN
SELECT *
FROM Products
WHERE InsertDate BETWEEN #StartDate AND #EndDate
ORDER BY InsertDate
OFFSET #Counter ROWS -- skip #Counter rows
FETCH NEXT 1000 ROWS ONLY -- take 1000 rows
SET #Counter = #Counter + 1000
END
Or you can get the time difference between the two dates and add the start date each time in a specific step and retrieve the data of that date.
For example, the date difference is 20 days. Increase the start date by 5 steps each time to the start date with the end date
I create another table to put Dates and if this table has any rows I can get 'EndDate', but if it has not any records I simply just use the date that I specified.
AccSync is the table that I insert details of my records and AccTransformation is the table wich I want to insert all of my records.
DECLARE #Count INT = (SELECT COUNT(*) FROM [AccTransaction])
DECLARE #Flag BIT = (SELECT IIF(#Count > 1, 1, 0))
DECLARE #End DATETIME = GETDATE();
DECLARE #Start DATETIME
IF(#Flag = 0)
BEGIN
SET #Start = CAST('2021-03-08' AS DATETIME2);
SET #Flag = 1
END
ELSE IF(#Flag = 1)
BEGIN
SET #Start = (SELECT TOP 1 EndDate FROM (SELECT EndDate FROM [AccSync] ORDER BY ActionDate DESC OFFSET 0 ROW) AS TT);
END
DECLARE #RealRowCount INT = (SELECT DISTINCT SUM(##ROWCOUNT) FROM [GetReport] (#Start, #End));
DECLARE #TransactionCount INT = (SELECT DISTINCT TransactionCount FROM [GetReport] (#Start, #End));
----------------------------------------------------------------------------------------------
WHILE (#RealRowCount <> #TransactionCount)
BEGIN
DECLARE #DiffDate INT = (SELECT DATEDIFF(SECOND, #Start, #End))
SET #End = DATEADD(SECOND, (#DiffDate/2), #Start)
SET #RealRowCount = (SELECT DISTINCT SUM(##ROWCOUNT) FROM [GetReport] (#Start, #End))
SET #TransactionCount = (SELECT DISTINCT TransactionCount FROM [GetReport] (#Start, #End))
END
----------------------------------------------------------------------------------------------
INSERT INTO [AccTransaction]
SELECT *
FROM [GetReport](#Start, #End)
----------------------------------------------------------------------------------------------
INSERT INTO [AccSync]
VALUES(NEWID(), GETDATE(), #Start, #End, ISNULL(#TransactionCount,0), DATEDIFF(SECOND, #Start, #End))
I have a blank table that has two columns [ID] and [MyDate].
I would like to populate that table with all of the days of the current year MINUS weekends.
Is there a way to do this with a SQL query?
In this case I am using MSSQL T-SQL
I do not have any example code, as I am at a loss on where to get started for this scenario.
Using a numbers (Tally) table helps you to avoid using loops.
If you don't already have a numbers table, you can use this script to create it:
SELECT TOP 10000 IDENTITY(int,0,1) AS Number
INTO Tally
FROM sys.objects s1
CROSS JOIN sys.objects s2
ALTER TABLE Tally ADD CONSTRAINT PK_NumbersTest PRIMARY KEY CLUSTERED (Number)
For more information about the creation of a numbers table, read this SO post.
Now that you have a numbers table, you can use a cte to generate the dates you want. I've used DATEFROMPARTS and GETDATE() to get Jauary 1st of the current year, if you are using a version of sql server below 2012 you need to use other methods for that:
DECLARE #StartDate Date,
#EndDate Date
SELECT #StartDate = DATEFROMPARTS(YEAR(GetDate()), 1, 1)
SELECT #EndDate = DATEADD(Year, 1, #StartDate)
Now, create a CTE to get the dates required using the numbers table, and insert the records from the cte to the table:
;WITH CTE AS
(
SELECT DATEADD(Day, Number, #StartDate) As TheDate
FROM Tally
WHERE DATEADD(Day, Number, #StartDate) < #EndDate
)
INSERT INTO WeekDays
SELECT TheDate
FROM CTE
WHERE DATEPART(WeekDay, TheDate) BETWEEN 2 AND 6
See a live demo on rextester.
This will do it. Here the 1 and the 7 represents Sunday and Saturday
CREATE TABLE T (
ID INT NOT NULL IDENTITY(1,1),
MyDate DATE NOT NULL)
DECLARE #Start DATE
DECLARE #End DATE
SET #Start = '20170101'
SET #End = '20171231'
WHILE #Start <= #End
BEGIN
IF (DATEPART(DW, #Start) NOT IN (1,7))
BEGIN
INSERT INTO T (MyDate) VALUES (#Start)
END
SET #Start = DATEADD(DAY, 1, #Start)
END
SELECT * FROM T
Here's my quick attempt at your problem. Just use your table instead
select
CAST('2017-03-15' as datetime) as datestuff
into #test
Delete from #test
DECLARE #Y datetime = CAST('2017-12-31' AS DATE)
while #y != '2017-01-01'
begin
if DATENAME(DW, #y) not IN ('SUNDAY', 'SATURDAY')
BEGIN
INSERT INTO #test
SELECT #y
END
SET #Y = DATEADD(DD, -1, #Y)
end
select * from #test
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()
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)
I wish to create a temp table with 1 datetime column and then fill it with date(30 days before today). I wish to do all these in a select-from statement.
I could do it with a "WITH" loop as below prior to the select-from statement. However, I wish to do it within a select-from statement.
declare #endDate datetime
set #endDate = dateadd(day,-30,getdate())
with CTE_Table (
Select dataDate = dateadd(day,-1,getdate()) from CTE_Table
where datediff(day,dataDate,#endDate) < 0
)
select * from CTE_Table
Please help... :....(
You can use SELECT ... INTO.
BTW Your recursive CTE is invalid. A fixed version is below
DECLARE #endDate DATETIME
SET #endDate = dateadd(day, -30, getdate());
WITH CTE_Table(dataDate)
AS (SELECT dateadd(day, -1, getdate())
UNION ALL
SELECT dateadd(day, -1, dataDate)
FROM CTE_Table
WHERE datediff(day, dataDate, #endDate) < 0)
SELECT dataDate
INTO #T
FROM CTE_Table
You could do:
CREATE TABLE #temptable
(
DateColumn DATETIME
)
INSERT INTO #temptable
SELECT dataDate FROM CTE_Table
What is the easiest way to populate a temp table with dates including and between 2 date parameters. I only need the 1st day of the month dates.
So for example if #StartDate = '2011-01-01' and #EndDate = '2011-08-01'
Then I want this returned in the table
2011-01-01
2011-02-01
2011-03-01
2011-04-01
2011-05-01
2011-06-01
2011-07-01
2011-08-01
This works even if the #StartDate is not the first of the month. I'm assuming that if it's not the start of the month, you want to begin with the first of the next month. Otherwise remove the +1.:
;WITH cte AS (
SELECT CASE WHEN DATEPART(Day,#StartDate) = 1 THEN #StartDate
ELSE DATEADD(Month,DATEDIFF(Month,0,#StartDate)+1,0) END AS myDate
UNION ALL
SELECT DATEADD(Month,1,myDate)
FROM cte
WHERE DATEADD(Month,1,myDate) <= #EndDate
)
SELECT myDate
FROM cte
OPTION (MAXRECURSION 0)
declare #StartDate date = '2014-01-01';
declare #EndDate date = '2014-05-05';
;WITH cte AS (
SELECT #StartDate AS myDate
UNION ALL
SELECT DATEADD(day,1,myDate) as myDate
FROM cte
WHERE DATEADD(day,1,myDate) <= #EndDate
)
SELECT myDate
FROM cte
OPTION (MAXRECURSION 0)
declare #StartDate datetime
declare #EndDate datetime
select #StartDate = '2011-01-01' , #EndDate = '2011-08-01'
select #StartDate= #StartDate-(DATEPART(DD,#StartDate)-1)
declare #temp table
(
TheDate datetime
)
while (#StartDate<=#EndDate)
begin
insert into #temp
values (#StartDate )
select #StartDate=DATEADD(MM,1,#StartDate)
end
select * from #temp
Works even if the #StartDate is not the first day of the month by going back to the initial day of the month of StartDate
this is tested in SQL 2008 R2
Declare #StartDate datetime = '2015-03-01'
Declare #EndDate datetime = '2015-03-31'
declare #temp Table
(
DayDate datetime
);
WHILE #StartDate <= #EndDate
begin
INSERT INTO #temp (DayDate) VALUES (#StartDate);
SET #StartDate = Dateadd(Day,1, #StartDate);
end ;
select * from #temp
Result:
DayDate
-----------------------
2015-03-01 00:00:00.000
2015-03-02 00:00:00.000
2015-03-03 00:00:00.000
2015-03-04 00:00:00.000

Interestingly, it is faster to create from enumerated data as per this article.
DECLARE #StartDate DATE = '10001201';
DECLARE #EndDate DATE = '20000101';
DECLARE #dim TABLE ([date] DATE)
INSERT #dim([date])
SELECT d
FROM
(
SELECT
d = DATEADD(DAY, rn - 1, #StartDate)
FROM
(
SELECT TOP (DATEDIFF(DAY, #StartDate, #EndDate))
rn = ROW_NUMBER() OVER (ORDER BY s1.[object_id])
FROM
sys.all_objects AS s1
CROSS JOIN
sys.all_objects AS s2
ORDER BY
s1.[object_id]
) AS x
) AS y;
On my machine, it's around 60% faster with large date ranges. The recursion method can populate 2000 years worth of data in around 3 seconds though, and looks a lot nicer, so I don't really recommend this method just for incrementing days.
Correction for null dates:
IF OBJECT_ID('tempdb..#dim') IS NOT NULL
DROP TABLE #dim
CREATE TABLE #dim ([date] DATE)
if not #Begin_Date is null and not #End_Date is null
begin
INSERT #dim([date])
SELECT d
FROM(
SELECT
d = DATEADD(DAY, rn - 1, #Begin_Date)
FROM
(
SELECT TOP (DATEDIFF(DAY, #Begin_Date, #End_Date))
rn = ROW_NUMBER() OVER (ORDER BY s1.[object_id])
FROM
sys.all_objects AS s1
CROSS JOIN
sys.all_objects AS s2
ORDER BY
s1.[object_id]
) AS x
) AS y;
end
CREATE TABLE #t (d DATE)
INSERT INTO #t SELECT GETDATE()
GO
INSERT #t SELECT DATEADD(DAY, -1, MIN(d)) FROM #t
