I am very new to USQL and wondering how to cast a "datetime" to "date" in a select statement. Also, how do i get rid of the millisecond and am/pm? I'd really appreciate any help on this. Thank you all.
Below is the code that works.Notice the parenthesis.
#date =
SELECT (datevalue).ToString("MM-dd-yyyy") AS date
FROM #datetime;
You can use inline C# to do that.
#rowset = SELECT dateTimeColumn.Date AS dateOnly FROM #anotherrowset;
To get rid of values you can use the dateTime.ToString(format), e.g. dateTime.ToString("mm/dd/yy hh:mm).
Interesting, I couldn't get the .Date working either, will look into it. In the meantime, using the .ToShortDateString() works. .ToString works as well.
E.g. code
#datetime =
SELECT *
FROM(
VALUES
(
DateTime.Now
),
(
new DateTime(2016, 05,31)
),
(
new DateTime(2015, 01, 01)
)) AS v(datevalue);
OUTPUT #datetime
TO "/output/datetime.txt"
USING Outputters.Text();
#date =
SELECT datevalue.ToShortDateString() AS date
FROM #datetime;
OUTPUT #date
TO "/output/date.txt"
USING Outputters.Text();
Alternate:
#date =
SELECT datevalue.ToString("MM-dd-yyyy") AS date
FROM #datetime;

I have value of column
datecolumn -> 2021-04-22T00:00:00.000
I want select using condition where like below:
SELECT * FROM 'tblDOISOAT' where datecolumn = strftime('%Y-%m-%d %H:%M:%S','2021-04-22 00:00:00')
I not get được value and i me met error 'Error: near "=": syntax error'. please help me
You have a typo, but your code works.
--------
dt
--------
2021-04-22T00:00:00.000
2021-04-23T01:00:00.000
--------
select strftime('%Y-%m-%dT%H:%M:%S.000', '2021-04-22 00:00:00') as 'datecode'
returns 2021-04-22T00:00:00.000
The query:
select dt from 't' where dt= strftime('%Y-%m-%dT%H:%M:%S.000', '2021-04-22 00:00:00')
returns the expected result: 2021-04-22T00:00:00.000
You forgot to include the correct formatting including T and .000 at the end.
remember that SQLite does not have a datetime data structure by default. You can read about SQLite data types here
If you are storing date/times as ISO-8601 text, you don't need to call strftime() to make comparisons. Just compare the 2 values:
select * from t1 where datecol = '2021-04-22T00:00:00.000';
The whole point of ISO-8601 strings is to make sure that date/time values compare lexicographically the same as temporally.
This is OrientDb 2.1.4.
The following query works fine:
select from SyncableHist where history_date <= date('2016-04-12 21:25:17','yyyy-MM-dd HH:mm:ss')
and returns as expected three records and each records has the value of history_date = '2016-04-12 21:25:17'. The history_date is a DATETIME type.
However this does not return any records:
select from SyncableHist where history_date = date('2016-04-12 21:25:17','yyyy-MM-dd HH:mm:ss')
Any ideas???
Thanks!
Format your date to string before compare. Not sure why, but probably have something extra like miliseconds or your database can't compare both this way.
select from SyncableHist where history_date.format('yyyy-MM-dd HH:mm:ss') = '2016-04-12 21:25:17'
When I write this query
SELECT Convert(datetime,Convert(varchar,CAST(GETUTCDATE() AS DATE))+' '+
CONVERT(varchar, cast(meas_pain.datetime AS time))) FROM meas_pain
it works for me but when I use the same part in WHERE clause it gives error 'Conversion failed when converting date and/or time from character string.'
SELECT schedules.id
FROM meas_pain LEFT JOIN schedules ON schedules.id=meas_pain.schd_id
WHERE meas_pain.schd_id=9150 AND
Convert(datetime,(Convert(varchar,CAST(GETUTCDATE() AS DATE))+' '+
CONVERT(varchar, cast(meas_pain.datetime AS time)))) <
CONVERT(datetime,DATEADD(Minute,0,getutcdate()))
can anybody explain??
I am not sure why this error does not appear in your select statement, since I can reproduce the error using just
SET DATEFORMAT DMY;
SELECT CONVERT(DATETIME, CONVERT(VARCHAR,CAST(GETUTCDATE() AS DATE)))
Example of Error
You are relying on localised conversion settings, you should use explicit conversion, e.g.
SET DATEFORMAT DMY;
SELECT CONVERT(DATETIME, CONVERT(VARCHAR, CAST(GETUTCDATE() AS DATE), 111), 111)
By explicitly defining the date format to convert both to varchar and from varchar (111) you can avoid any implied conversions.
However, If your dates/times are stored as such there should be no need for all the conversion to and from varchar, this is just more chance for things to go wrong, and unnecessary work, you can simply add a time to a datetime. e.g.
DECLARE #Date1 DATETIME = DATEADD(HOUR, 1, GETUTCDATE()),
#Date2 DATETIME = DATEADD(DAY, 1, GETUTCDATE());
SELECT [Date1] = #Date1,
[Date2] = #Date2,
[Date1/Time2] = CAST(CAST(#Date1 AS DATE) AS DATETIME) +
CAST(#Date2 AS TIME);
From what I can gather from your query you are just trying to get results where the time of meas_pain.datetime is less that the current UTC time, regardless of date. So you should be able to simplify your query to just:
SELECT schedules.id
FROM meas_pain
LEFT JOIN schedules
ON schedules.id = meas_pain.schd_id
WHERE meas_pain.schd_id = 9150
AND CAST(meas_pain.[DateTime] AS TIME) < CAST(GETUTCDATE() AS TIME);
And remove further redundant conversions.
Simplified example on SQL Fiddle
ADENDUM
Apparently this time comparison is not what you are after (although it is what the query you have posted is doing), so I am assuming GETUTCDATE() is just for demonstration.
The conversion you are trying to perform is equivalent to this:
CAST(CAST(GETUTCDATE() AS DATE) AS DATETIME) + CAST(meas_pain.[DateTime] AS TIME)
Another example on SQL Fiddle using the above conversion
I am stuck at a place where i am able to proceed with a sqlite SELECT query. My query is like this. I dont know if it tis correct or wrong. Please help me.
NSString *querySQL = [NSString stringWithFormat: #"SELECT * FROM CLAIMS WHERE DATE = \"%#\" AND TIME = \"%#\"",splitdate,splittime];
Any help is appreciated.
Thanks
SQL uses ' for strings, so at the very least your query should look like:
SELECT * FROM CLAIMS WHERE DATE = '%#' AND TIME = '%#'
A further step would be to make those things parameters:
SELECT * FROM CLAIMS WHERE DATE = #date AND TIME = #time
And a further improvement is to use the SQL type datetime for the field so you'll only need one instead of 2:
SELECT * FROM CLAIMS WHERE DATE = #date
Hi all I have the following Query made using the Query Builder in Visual Studio.
SELECT Schd_ID, Schd_Date, Schd_Avaliable, Schd_Nights, Schd_Price, Accom_ID
FROM Schedule
WHERE (Schd_Avaliable = 'Yes') AND (Accom_ID = Accom_ID)
I want to add another WHERE statement which adds where Schd_Date is after todays date, any ideas?
Assuming SQL Server, the GETDATE() function returns the date and time the statement was run at:
WHERE Schd_Date > GETDATE()
Use the following for finding dates greater than the current date at midnight:
WHERE Schd_Date > DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))
However, CURRENT_TIMESTAMP is the ANSI means of getting the current date and time in a database. Beyond that, date functionality is not consistent between databases so you'd have to tell us what you are dealing with for better answers.
If this is SQL Server you could use the GETDATE() function to return the current date and compare against it:
SELECT
Schd_ID, Schd_Date, Schd_Avaliable, Schd_Nights, Schd_Price, Accom_ID
FROM
Schedule
WHERE
(Schd_Avaliable = 'Yes')
AND
(Accom_ID = Accom_ID)
AND
(Schd_Date > GETDATE())
SELECT Schd_ID, Schd_Date, Schd_Avaliable, Schd_Nights, Schd_Price, Accom_ID
FROM Schedule
WHERE (Schd_Avaliable = 'Yes') AND (Accom_ID = Accom_ID) AND (GETDATE() < Schd_Date)
This should work
I guess this expression can be used as a date representing the current date on the format yyyy-mm-dd (without the hours,minutes and seconds).
(Datepart('yyyy',getdate())+ '-' +Datepart('m',getdate())+ '-' + Datepart('d',getdate()))
therefore
SELECT Schd_ID, Schd_Date, Schd_Avaliable, Schd_Nights, Schd_Price, Accom_ID
FROM Schedule
WHERE (Schd_Avaliable = 'Yes') AND (Accom_ID = Accom_ID) AND
(Schd_Date >= (Datepart('yyyy',getdate())+ '-' +
Datepart('m',getdate())+ '-' +
Datepart('d',getdate())))
