I have a stored procedure that joins two tables of hotel booking data, however, the API that I pull my data from uses Unix time. I need to convert this to DateTime to match with my companies fields.
Currently, my conversion looks like this.
IIF([start] IS NOT NULL,
CONVERT(varchar(10), [start], 103),'') as 'ArrivalDate'
This just returns the value 1547310796 so no conversion has been done.
How do I convert the value to match 103 Date Time?
This should do it:
SELECT DATEADD(second, 1547310796 - DATEDIFF(second, GETDATE(), GETUTCDATE()), '1970-01-01')
The DATEDIFF(second, GETDATE(), GETUTCDATE()) part will give you how far behind you are from UTC time. You need to subtract that many seconds from the UTC timestamp to get the local time.
I just wanted to come back to this and add another answer in that works if you just want the date and not time.
SELECT cast(DATEADD(S,[start], '1970-01-01') as date) as 'ArrivalDate'
works on Oracle/Sql
select TO_date ('19700101000000','YYYYMMDDHH24MISS') + NUMTODSINTERVAL(<YOUR_COLUMN>+ decode (sessiontimezone, '+01:00', 3600, '+02:00', 7200, 0) , 'SECOND') as ArrivalDate

Not being that great at sql, i've reached my limit.
I have a date in the yyyy/mm/dd format and i need to get all records "from a week ago"
I think i need some conversion stuff to be done cause this
d.date_begin >= DATEADD(day,-7, GETDATE())
is not working :), i'm TERRIBLE at convert and data type..
This will work if you want records from 7 days ago up to and including today's records
CAST(d.date_begin AS DATE) >= CAST(DATEADD(day,-7, GETDATE()) AS DATE)
where DATEDIFF(month,Your_date_column,getdate()) < 3
SQL server 2012 onwards, if date_begin is of datatype date
where d.date_begin >= cast(DATEADD(day,-7, GETDATE()) as date)
This will get anything in the last 7 days, regardless of time
You should store date/time values using native formats. Ok, sometimes we cannot. But you can easily convert your values to the correct format:
where cast(replace(d.date_begin, '/', '') as date) >= DATEADD(day, -7, GETDATE())
I should note that SQL Server is pretty good about conversions, so your initial code should not generate any errors -- unless you have unusual internationalization settings.
Or, actually, a better way to do this is to convert the current value to a string:
where d.date_begin >= format(dateadd(day, -7, getdate()), 'yyyy/MM/dd')
This is better because it is "sargable", meaning that SQL Server can use an index on the column if available.
SELECT * FROM tbl_name
WHERE date >= curdate() - INTERVAL DAYOFWEEK(curdate())+6 DAY
AND date < curdate() - INTERVAL DAYOFWEEK(curdate())-1 DAY
Don't manipulate d.date_begin. Making calculation on a column while comparing can give bad performance. You should manipulate getdate() to get the same format as d.date_begin. In this case it works because the format is yyyy/MM/dd - the comparison will give the same result as if both columns were date columns.
WHERE
d.date_begin >= convert(char(10),DATEADD(day,-7, GETDATE()), 111)
I have SQL script that selects everything from current day.
SELECT [ClientID] from [logs] where Date > CONVERT (date, SYSDATETIME())
Date is type of DateTime.
How to get everything within last 3 days? I suppose I need subtract 3 days from function SYSDATETIME() result, but how?
SELECT [ClientID] from [logs] where Date > DATEADD(day, -3, CONVERT (date, SYSDATETIME()))
Use GETDATE() : Yes, it gets date from system!
Returns the current database system timestamp as a datetime value
without the database time zone offset. This value is derived from the
operating system of the computer on which the instance of SQL Server
is running.
Query:
SELECT [ClientID] from [logs] where ( Date > GETDATE() - 3)
More Reference:
GETDATE Detailed Documentation
For mysql use this:
SELECT DATE_ADD(CURRENT_DATE, INTERVAL - 3 DAY);
Use BETWEEN
SELECT ClientID
FROM logs
WHERE Date BETWEEN SYSDATETIME() AND SYSDATETIME() - 3
Using BETWEEN is nice. I also prefer the DATEADD function. But be aware of the fact that the SYSDATETIME function (or I would us GETDATE()) also includes the time which would mean that events before the current time but within the three day period may not be included. You may have to convert both sides to a date instead of datetime.
SELECT [ClientID] from [logs] where Date > DATEADD(day, -3, SYSDATETIME())
In my case:
select * from Table where row > now() - INTERVAL 3 day;
So you can fetch all of 3 days ago!
I have dates stored in a sql server database as nvarchar but I need to create a report and pull out data from the last day base on the date.
I use this when the data type is a DateTime:
SELECT *
FROM [table]
WHERE timein >= DateAdd(hh, -24, GETDATE())
I think I need to convert the GETDATE() -24 to a string to compare it to the db
The format needs to be like this:
April-30-15
Can anyone help me create a query that will select records for the past 24 hours using this date format?
Convert your timeIn string to a date and compare using dates not strings. If you replace the hyphens with spaces it will be able to cast to a date. I assume you want values since the start of previous day (ignoring the current time) so I cast that to a date also.
SELECT *
FROM [table]
WHERE cast(replace(timein, '-', ' ') as date) >= cast(DateAdd(dd, -1, GETDATE()) as date)
I am trying to get tomorrows date in a sql statement for a date comparison but it is not working.
Below is my code:
select *
from tblcalendarentries
where convert(varchar,tblcalendarentries.[Start Time],101)
= convert(varchar, GETDATE() +1, 101)
To get tomorrows date you can use the below code that will add 1 day to the current system date:
SELECT DATEADD(day, 1, GETDATE())
GETDATE()
Returns the current database system timestamp as a datetime value without the database time zone offset. This value is derived from the operating system of the computer on which the instance of SQL Server is running.
DATEADD(datepart , number , date)
Returns a specified date with the specified number interval (signed integer) added to a specified datepart of that date.
So adding this to your code in the WHERE clause:
WHERE CONVERT(VARCHAR, tblcalendarentries.[Start Time], 101) =
CONVERT(VARCHAR, DATEADD(DAY, 1, GETDATE()), 101);
First off, GETDATE() will get you today's date in the following format:
2013-04-16 10:10:02.047
Then using DATEADD(), allows you to add (or subtract if required) a date or time interval from a specified date. So the interval could be: year, month, day, hour, minute etc.
Working with Timezones?
If you are working with systems that cross timezones, you may also want to consider using GETUTCDATE():
GETUTCDATE()
Returns the current database system timestamp as a datetime value. The database time zone offset is not included. This value represents the current UTC time (Coordinated Universal Time). This value is derived from the operating system of the computer on which the instance of SQL Server is running.
Try the below:
SELECT GETDATE() + 1
This adds one day to current date
Specify size of varchar in convert()
where convert(varchar(11),tblcalendarentries.[Start Time],101) = convert(varchar(11), GETDATE() +1, 101)
I would write:
where
DATEADD(day,DATEDIFF(day,0,tblcalendarentries.[Start Time]),0) =
DATEADD(day,DATEDIFF(day,0,GETDATE()),1)
This avoids converting dates to strings entirely, whilst also removing the time portion from both values.
I have a field in a table Event.EventDate and it's of the data type DATE rather than DATETIME and then I have a view that has the following WHERE clause:
WHERE e.EventDate >= CAST(CONVERT(VARCHAR(MAX), GETDATE(), 101) AS DATETIME)
As you can see, I'm just trying to get all events >= today's date. The above code works, but it's ugly. I tried this ...
WHERE e.EventDate >= CONVERT(VARCHAR(MAX), GETDATE(), 101)
... and this ...
WHERE e.EventDate >= CONVERT(DATETIME, GETDATE(), 101)
... but those didn't work, they gave me every event > today's date. However, even if the above worked, it's still ugly.
Isn't there a better way?
Try:
WHERE e.EventDate >= cast(getdate() as date)
To cast getdate() into a date time. It's a clean way in SQL Server 2008 and up to strip out the time portion of a datetime type.
Using Shan Plourde's method is certainly cleaner and quicker, but for the more general case when you want to round a datetime to a particular time interval, I use
dateadd(dd,datediff(dd,0,[datetime column]),0)
where dd stands for day, and can be replaced with mm (month), hh (hour), mi (minute), and probably others.
If you want to get fancy and round to, say, 15 minute intervals, you can use
dateadd(mi,
-datepart(mi,[datetime column])%15,
dateadd(mi,datediff(mi,0,[datetime column]),0)
)
where % is the modulo operator. You'll get wacky results for this if you don't use an interval that divides 60 evenly.
