i have a stored procedure like this:
ALTER procedure [dbo].[startandenddtime]
#startdate nvarchar(100)
as begin
declare #date3 nvarchar(100) = cast(CONVERT(varchar(100), #startdate + ' 16:59:59', 120) as datetime)
select date3 as startdate
end
If i pass my startdate as 2013-05-08 i am getting out put as :
but i want to get out put as 2013-05-08 16:59:59.000..so how i can convert this format
is this date time i can store in nvarchar varibale
Try like this
DECLARE #StartDate NVARCHAR(100)='2013-05-08'
SELECT CONVERT(VARCHAR,#StartDate+'16:59:59', 121)

SQL Fiddle
try this
ALTER procedure [dbo].[startandenddtime]
#startdate nvarchar(100)
as begin
declare #date3 nvarchar(100) = cast(CONVERT(VARCHAR(24),#startdate ,121)) as datetime)
select date3 as startdate
end
For more in details see this, http://technet.microsoft.com/en-us/library/ms187928.aspx
try this
Select cast(CONVERT(varchar(100), #startdate + ' 16:59:59') as date)
Or
Select cast(CONVERT(varchar(100), #startdate + ' 16:59:59') as datetime)
Try this :
Declare #dt varchar(20);
Declare #startdate varchar(20)='2013-05-08';
SET #dt= CONVERT(VARCHAR(20), CONVERT(datetime,#startdate+' 16:59:59'), 100)
Select #dt;
Just don't cast varchar value to datetime
edit: If you don't get what i meant in my comment:
convert(varchar, convert(datetime, #startdate + ' 16:59:59', 120), 120)

In SQL Server, I want to get days from date to date. Example: from 2015/12/28 to 2016/01/02, the result as
2015/12/28
2015/12/29
2015/12/30
2015/12/31
2016/01/01
2016/01/02
DECLARE #STARTDATE DATETIME = '2015-12-28'
DECLARE #ENDDATE DATETIME = '2016-01-02'
SELECT BETWEEN #STARTDATE AND #ENDDATE AS DAYS
Use CTE
DECLARE #STARTDATE DATE = '2015-12-28'
DECLARE #ENDDATE DATE = '2016-01-02'
;WITH CTE AS
(
SELECT #STARTDATE As dt
UNION ALL
SELECT DATEADD(D,1,dt) AS dt
FROM CTE
WHERE dt < #ENDDATE
)
SELECT * FROM CTE
You could build a calendar table, which would probably come in handy down the road. Or you could use a loop.
DECLARE #ENDDATE DATETIME = '2016-01-02'
DECLARE #DAY DATETIME = '2015-12-28'
WHILE #Day <= #ENDDATE
BEGIN
SELECT #DAY
SET #DAY = DATEADD(DD,1,#DAY)
END
Or for all of the days in one result set:
DECLARE #ENDDATE DATETIME = '2016-01-02'
DECLARE #DAY DATETIME = '2015-12-28'
DECLARE #TABLE TABLE (DATE DATETIME)
WHILE #Day <= #ENDDATE
BEGIN
INSERT #TABLE
VALUES (#DAY)
SET #DAY = DATEADD(DD,1,#DAY)
END
SELECT *
FROM #TABLE
You can specify the dates in your WHERE clause. For example, WHERE date >=#STARTDATE AND date <=#ENDDATE. That should return the full date in your results.
using Numbers table
select dateadd(day,n,startdate)
from numbers
where dateadd(day,n,startdate)<=enddate
order by n
Given:
CREATE PROCEDURE [dbo].[sp_func]
#StartDate DATE
, #EndDate DATE
AS
select * from [TRANS] where
(#StartDate IS NULL OR [TransDate] >= #StartDate) AND (#EndDate IS NULL OR [TransDate] <= #EndDate)
Both this:
declare #StartDate DATE = '2015-01-01'
declare #EndDate DATE = '2015-12-31'
exec dbo.sp_func #StartDate, #EndDate
And this:
declare #StartDate DATE = NULL
declare #EndDate DATE = NULL
exec dbo.sp_func #StartDate, #EndDate
...return rows as expected.
However, both of these calls return 0 rows:
exec dbo.sp_func '2015-01-01', '2015-12-31'
exec dbo.sp_func NULL, NULL
Am I fundamentally misunderstanding something here? As far as I can recall, I’ve always called sp’s passing dates like 'YYYY-MM-DD' with absolutely no issues.
Possibly related...this:
select CAST('2015-01-01' AS DATE), CAST('2015-12-31' AS DATE)
returns:
2015-01-01 2015-12-31
Whereas this:
exec dbo.sp_func CAST('2015-01-01' AS DATE), CAST('2015-12-31' AS DATE)
returns:
Incorrect syntax near '2015-01-01'.
I feel like I'm taking crazy pills.
I discovered the problem, it was stupidity.
Not shown in the example, I had other parameters in my production code, one of which was:
#JobClass VARCHAR(10) = 'PRODUCTION'
What I had been doing wrong in my test code was passing NULL to this, and incorrectly thinking that a passed NULL to this would instead default to 'PRODUCTION', whereas this defaulting only happens when the parameter is not passed at all. Which I knew of course. One of those days.
A couple of things , I would re-write the whole proc as below:
Procedure Definition
CREATE PROCEDURE [dbo].[usp_Proc] --<-- do not use sp_
#StartDate DATE = NULL
, #EndDate DATE = NULL
AS
BEGIN
SET NOCOUNT ON;
DECLARE #sql NVARCHAR(MAX);
SET #sql = N' select * from [TRANS] where 1 = 1 '
+ CASE WHEN #StartDate IS NOT NULL
THEN N' AND [TransDate] >= #StartDate' ELSE N' ' END
+ CASE WHEN #EndDate IS NOT NULL
THEN N' AND [TransDate] <= #EndDate ' ELSE N' ' END
Execute sp_executesql #sql
,N'#StartDate DATE,#EndDate DATE '
,#StartDate
,#EndDate
END
Execute Procedure
exec dbo.usp_Proc '20150101', '20151231' --<-- Pass date in ANSI format 'YYYYMMDD'
How about specifying the variable names and values like this:
EXECUTE dbo.sp_func #StartDate='2015-01-01',#EndDate='2015-12-31'
Works on my machine... :)
In SQL, I can use wildcard '%' on string and Select statement will show all the records like
select * from tablea where title like '%'
My question is what if both the start and end date are empty in the BETWEEN & AND function in Select statement.
Example
`select * from table where inputdate between '2014-01-01'` and '2014-01-31'
It works fine in this statement because there are start and end date.
What if there isn't any start and end date, and I want to show all the records?
select * from table where inputdate between '%' and '%' <--- not working.
Many thanks.
You can write your query in a way that inputdate column is evaluated against the value passed or if the no value is passed to #StartDate variable just pick earliest possible date,
I have select 1900-01-01 as the earliest date but depending on your column type you can pick a more appropriate substitute start and end dates.
DECLARE #StartDate DATE = '2014-01-01'
DECLARE #EndDate DATE = '2014-01-31'
select * from table
where inputdate >= COALESCE(#StartDate, '19000101')
and inputdate <= COALESCE(#EndDate , '99991231')
Dynamic SQL
Another better way of handling this kind of query with optional parameters will be using dynamic sql something like this...
DECLARE #StartDate DATE = '2014-01-01'
DECLARE #EndDate DATE = '2014-01-31'
DECLARE #Sql NVARCHAR(MAX);
SET #Sql = N'SELECT * FROM Table 1 = 1 '
+ CASE WHEN #StartDate IS NOT NULL THEN
N' AND inputdate >= #StartDate ' ELSE N' ' END
+ CASE WHEN #EndDate IS NOT NULL THEN
N' AND inputdate <= #EndDate ' ELSE N' ' END
Execute sp_executesql #Sql
,N'#StartDate DATE, #EndDate DATE'
,#StartDate
,#EndDate
wildcard can only be used on string, But since you mentioned the column is Date, you can do something better. Date min/max has been defined in almost all DBMS, IDK about the max but the min is usually January 1, 1753. so you can try between ' January 1, 1753' and 'date max'
SELECT * FROM table t
WHERE t.Date >= IIF(#FromDate IS NULL, t.Date, #FromDate)
AND t.Date <= IIF(#ToDate IS NULL, t.Date, #ToDate)
works fine.
How to convert given date format to MM/dd/yyyy HH:mm:ss
I tried this one below but not achieved. Can anyone help me?
SELECT CONVERT(VARCHAR(20), GETDATE(), 120)
Supported by SQL Server 2005 and later versions
SELECT CONVERT(VARCHAR(10), GETDATE(), 101)
+ ' ' + CONVERT(VARCHAR(8), GETDATE(), 108)
* See Microsoft's documentation to understand what the 101 and 108 style codes above mean.
Supported by SQL Server 2012 and later versions
SELECT FORMAT(GETDATE() , 'MM/dd/yyyy HH:mm:ss')
Result
Both of the above methods will return:
10/16/2013 17:00:20
Try below:
SELECT CONVERT(VARCHAR(20), GETDATE(), 101)
use
select convert(varchar(10),GETDATE(), 103) +
' '+
right(convert(varchar(32),GETDATE(),108),8) AS Date_Time
It will Produce:
Date_Time 30/03/2015 11:51:40
Declare #month as char(2)
Declare #date as char(2)
Declare #year as char(4)
declare #time as char(8)
declare #customdate as varchar(20)
set #month = MONTH(GetDate());
set #date = Day(GetDate());
set #year = year(GetDate());
set #customdate= #month+'/'+#date+'/'+#year+' '+ CONVERT(varchar(8), GETDATE(),108);
print(#customdate)
I want to select from table where date with between
but problem is that in database there is not datetime column there is separated dateTime year, month and day
does it possible to create new variable inside stored procedure something like that?
checkin = new DateTime(year, month, day)
this year month and day are columns in datatable
You can convert string to DateTime using the function below:
convert(datetime, '02/15/2012', 101) -- mm/dd/yyyy
You could try something like:
-- dateadd formula borrowed from
-- http://weblogs.sqlteam.com/jeffs/archive/2007/01/02/56079.aspx
with includeDate as (
select column1,
column2,
column3,
dateadd(month,(([year]-1900)*12)+[month]-1,[day]-1) as date
from yourTable
)
select *
from includeDate
where date between #startDate and #endDate
Of course in your stored procedure, you would populate the query with the values from your table, the code below is an example of converting the separate date fields into one datetime value.
I don't know the data type of your day, month and year fields but the following should work if you have an int value:
declare #day int
declare #month int
declare #year int
declare #fulldate smalldatetime
set #day = '1'
set #month = '9'
set #year = '2012'
SELECT #fulldate = Convert(smalldatetime, Cast(#month as varchar(2)) + '/'
+ Cast(#day as varchar(2)) + '/' + Cast(#year as varchar(4)), 101)
select Convert(varchar(10), #fulldate, 101)
If the values are stored as a string:
declare #day varchar(2)
declare #month varchar(2)
declare #year varchar(4)
declare #fulldate smalldatetime
set #day = '1'
set #month = '9'
set #year = '2012'
SELECT #fulldate = Convert(smalldatetime, #month + '/'
+ #day + '/' + #year, 101)
select Convert(varchar(10), #fulldate, 101)
