I have a column of data with this date format mm/dd/yyyy. I would like to covert to this to the format yyyy-mm-dd for (SQLite usage). How could I achieve this?
UPDATE Table_Name
SET Column_Name = 'yyyy-mm-dd' format
I have tried substr, ltrim, rtrim (None of this work for my case).
My data are dynamic.
Sample
Column_Name
6/1/2004
06/25/2004
7/1/2003
6/1/2004
6/1/2004
09/19/2003
09/30/2003
09/30/2003
09/30/2003
09/30/2003
The Goal: Extract only month from this Column (Without displaying unnecessary stuff)
Thank you.
The syntax for extracting a specific date element from a date field is to use strftime.
SELECT strftime('%m', Column_Name) AS month which is your second question. For reconstituting the date data you could use (at least in JavaScript) substr to split the date out then format it as you require. Also see this post:Get month from DATETIME in sqlite

I need to query a cell that contains a datetime but its formatted by default when I import it to only show the date.
31/7/2020 19:18:58 (in reality it's like this)
31/7/2020 (but it shows this)
So when I run this query:
=QUERY(A5:R10, "select K")
It returns only the date no matter what I do:
31/07/2020
I've tried:
Options
Formatted like "yyyy-MM-dd HH:mm" it returns 00:00
Filter by datetime or timestamp
Used '"&Text(now(), "yyyy-mm-dd HH:mm"&"' or something like that
The question is:
Is there a way to do what I'm trying to do without reformatting the imported cells?
link to test it:
https://docs.google.com/spreadsheets/d/14rGPngGvFXGP8txMS2yFo1v4gPcI4K1oYWj_8yt2Uq8/edit?usp=sharing
when I select one cell with F2 it shows the time:
Thanks a lot for your time!
select column B and format it as date time
or without reformating it:
=ARRAYFORMULA(QUERY(1*(B2:B4&""), "format Col1 'yyyy-mm-dd hh:mm:ss'"))
or:
=ARRAYFORMULA(QUERY(TEXT(B2:B4, "yyy-mm-dd hh:mm:ss"), "select *"))
Just make sure your cells are formatted as Automatic
If not, even if you use the format clause of the query, the clause will be ignored
I have a sqlite table within a column type DATE. Why doesn't this query work? I save my date in this format: dd-MM-YYYY
SELECT * FROM scadenze where data < strftime ('%d-%m-%Y', '31-03-2017') ;
This is not one of the supported date formats. Better use yyyy-mm-dd.
I have an sqlite table with with 2 date columns (beginning & end). I am looking for a query that returns the date range a date falls in. e.g Checking range where 10-02-2016 falls given 2 records as follows
(01-02-2016 - 12-02-2016) & (13-02-2016 - 20-02-2016)
Clearly it falls in the first range but how do I do it in SQLITE. Please help?
I think the problem is next SQLite requires dates to be in format YYYY-MM-DD. With that format you could write a simple query:
select * from table where yourdate between begin and end
If you can't change your format you should look at next sqlite functions https://sqlite.org/lang_datefunc.html
Also you can try substr function to cotact date in needed format.
I cannot get date ranges to work properly in a query using SQLite3
Create And Populate Table:
create table dates(myDate DATE);
insert into dates values('2012-10-1');
insert into dates values('2012-10-2');
insert into dates values('2012-10-3');
insert into dates values('2012-10-4');
insert into dates values('2012-10-5');
insert into dates values('2012-10-6');
insert into dates values('2012-10-7');
insert into dates values('2012-10-8');
insert into dates values('2012-10-9');
insert into dates values('2012-10-10');
Query:
select * from dates where myDate >= '2012-10-1' and myDate < '2012-10-31';
Results:
2012-10-1
2012-10-2
2012-10-3
2012-10-10
Where are 10-4 - 10-9?
I get the same results if I use between:
select * from dates where myDate BETWEEN '2012-10-1' AND '2012-10-30';
If I change either of the queries to use '2012-11-1' as the end date, they work properly.
Any help would be greatly appreciated!
Date values must be in the format yyyy-mm-dd with fixed-width fields.
This is required because SQLite has no native date format; to compare date strings correctly, fields with the same meaning must always be at the same position in the string.
I want to show a date in DD-MM-YYYY format in a datagrid. By default, SQLite stores the data in date-time format. So how can I convert date-time format to date format in flex by using SQLite?
You can use strftime, from Date And Time Functions.
Example:
SELECT strftime('%d-%m-%Y', 'now')
output:
10-06-2010
Look up Java until Date. It has methods to convert and is supported in SQLite. However it is mostly deprecated and replaced with Calender.
