I know this question has probably been asked but I cant for the life of me figure out what is wrong with my datetime value that mysql doesnt seem to like.
In my situation, I am appending 'explain ' in front of every query to see what the explain plan looks like. This is done BEFORE the actual query is run. The problem is mysql doesnt like the date format in the explain but the regular query runs fine.
This is the error I recieve:
SQL Error: 1292, SQLState: 22007
Incorrect datetime value: '11/19/2015 19:49:34.076' for column 'createdTime' at row 1
Query is:
explain delete from LoggableActivity where createdTime<'11/19/2015 19:49:34.076'
What is wrong with this format? it looks good to me...
And why only the query appended with explain isn't working?
Some more info:
I am using an entity manager in java to create and execute the queries and the date being generated is a result of Java's 'new Date(milliseconds)'.
Thanks
MONTH/DAY/YEAR is not (repeat not) the best sequence in the world
YEAR/MONTH/DAY is much better
try this:
explain
select from LoggableActivity
where createdTime<'2015-11-19 19:49:34.076'
Consider this article at wikipedia
https://en.wikipedia.org/wiki/Date_format_by_country
Look at how many people in the world use either a "big endian" (yyyy-mm-dd) or "little endian" (dd-mm-yyyy) date format. It is far wiser to treat date strings as "big endian". In particular starting a date string by year reduces possible confusion with dates where the day number is less than 13.

I have a large dataset with employees' time entries. The current date format is MM/dd/yyyy. However, I need to convert all the dates into yyyy-MM-dd format.
I have tried the following:
Update human_resources.timekeeping
Set Actual_Date = str_to_date(Actual_Date,'%d-%m-%Y');
Got the errror messsage Error Code: 1411. Incorrect datetime value: '' for function str_to_date.
My SQL version is 5.7.18-log.
I tried to view SQL mode using SELECT ##sql_mode; and I got NO ENGINE SUBSTITUTION.
I have tried to retrieve the value like shown below and it was working fine.
Converting varchar mm/dd/yy to date format yyyy-mm-dd
However, updating the data would not work. I need to update the actual records, not insert new records.
Hope someone can help me regarding this. Thank you in advance!
EDIT: The data type for Actual_Date is VARCHAR.
Apologies if my explanation may be a bit confusing. But I am using this data set to display and filter time entries in a gridview. When I am filtering dates, say for example (01/15/2022-01/25/2022), data from 2021 is also being displayed. When I tried to manually change the format of some of my data in sql to yyyy-MM-dd, my code seemed to be working fine. The problem is there are a lot of data in this table, which is why manually updating the format is impossible. What is the first thing that I need to do? I'm sorry this is all still a bit confusing for me.
My apologies if you have already taken the following things into consideration but I thought them worth mentioning.
Given that you say this is a "large dataset" I assume this is a table that is currently in use. Does the existing application rely on the Actual_Date being in that string format? Does it rely on a fixed number of columns in the table? Some poorly written applications can be very brittle when it comes to changing underlying data structure.
You may want to consider creating a copy of the current table, modifying the structure of the copy, and replacing the original with a view with the same columns and formats as the original. This way you get improved data but reduce risk to existing application.
In the title and first line of your question you state that the current format is MM/dd/yyyy
Update human_resources.timekeeping Set Actual_Date = str_to_date(Actual_Date,'%m/%d/%Y');
Your separator is / not -
%d-%m-%Y >> %d/%m/%Y
I'm trying to query this API, filtering by the RptDt field, which is type esriFieldTypeDate.
The basic query looks like this:
https://dhsgis.wi.gov/server/rest/services/DHS_COVID19/COVID19_WI_V2/MapServer/11/query?where=1%3D1&outFields=*&outSR=4326&f=json
It's easy to filter a numeric variable like POS_CUM_SUM like so:
"https://dhsgis.wi.gov/server/rest/services/DHS_COVID19/COVID19_WI_V2/MapServer/11/query?where=%20(POS_CUM_CP%20%3D%200%20OR%20POS_CUM_CP%20%3D%2010)%20&outFields=*&outSR=4326&f=json"
I can't figure out how to format the minimum and maximum arguments for the date field RptDt.
because the attributes of RptDt are formatted as unix timestamps: 1642255200000, 1642428000000. But that returns error code 400.
https://dhsgis.wi.gov/server/rest/services/DHS_COVID19/COVID19_WI_V2/MapServer/11/query?where=%20(RptDt%20%3D%20'1642255200000'%20OR%20RptDt%20%3D%20'1642428000000')%20&outFields=*&outSR=4326&f=json
Then, I noticed that the field length for RptDt is 8, so I tried rounding the unix timestamp to 8 digits (16422552, 16424280), but that also gives error code 400.
I tried using YYYYMMDD format (20210101 to 20211231), this didn't give an error, but the response has no features. Most of the dates do fall this period.
https://dhsgis.wi.gov/server/rest/services/DHS_COVID19/COVID19_WI_V2/MapServer/11/query?where=%20(RptDt%20%3D%20%2720210101%27%20OR%20RptDt%20%3D%20%2720211231%27)%20&outFields=*&outSR=4326&f=json
I haven't been able to find a solution in the ArcGIS REST APIs documentation. Does anyone understand what's missing from my queries?
The correct format is 'YYYY-MM-DD'. This query works. The relevant bit is where=RptDt>'2022-01-01'.
https://dhsgis.wi.gov/server/rest/services/DHS_COVID19/COVID19_WI_V2/MapServer/11/query?where=RptDt>'2022-01-01'&outFields=*&outSR=4326&f=json
Thanks to JamieKelly1 at the Esri Community Forum for answering this question.
For anyone else stumbling upon this one after getting the -2147220985 (which btw means bad SQL query), the full url I used had to contain Date before the actual date like so Date'2015-02-02' not just '2015-02-02'. Also, you cannot use epoch timestamp in miliseconds in the query builder (at least not for open data dc).
Example url:
https://maps2.dcgis.dc.gov/dcgis/rest/services/DCGIS_DATA/ServiceRequests/MapServer/6/query?where=%20(ADDDATE%20%3D%20Date'2015-02-02'%20OR%20ADDDATE%20%3D%20Date'2015-02-03')%20&outFields=*&outSR=4326&f=json
To search between two dates:
https://maps2.dcgis.dc.gov/dcgis/rest/services/DCGIS_DATA/ServiceRequests/MapServer/6/query?where=ADDDATE BETWEEN DATE '2015-01-09 00:00:00' AND DATE '2015-01-09 12:00:00'&outFields=*&outSR=4326&f=json
I'm having trouble building a query in Access 2013. The database isn't mine and the only thing I really have control over is this query. There is a table, I'm pulling 7 fields from it and eventually adding an 8th field to the query to do some string manipulation.
However, I keep getting getting "Syntax error in date in query expression 'fieldname'." error whenever I click on the arrow to sort the fields. The odd thing is these errors pop up when sorting non-date fields. When sorting the date field I get "Syntax error (missing operator) in query expression 'Release Date'."
This happens after a fresh build. I have no WHERE conditions, just SELECT and FROM. Ideas?
Here's the sql query, though I'm mainly working in the query design view:
SELECT Transmissions.[Job#], Transmissions.[Part#], Transmissions.TransmissionSN, Transmissions.Status, Transmissions.[Release Date], Transmissions.[Build Book Printed], Transmissions.[ID Tags Required]
FROM Transmissions;
Well... it seems you are the lucky inheritor of a poorly designed database.
Using special characters in a field name is just asking for trouble. And you've found what that trouble is.
Access uses the # sign to designate a Date type for query comparisons. Such as:
dtSomeDate = #2/20/2017#
You surround the date with the # signs.
In your case, the query thinks [Job#] and [Part#] are trying to wrap dates. But of course, that's not the case and thus it fails.
You can try a couple of work arounds. (I leave it to you to experiment.)
1) You can try to rename the problem fields within your query. So that:
Transmissions.[Job#] becomes Transmissions.[Job#] as JobNum
and
Transmissions.[Part#] becomes Transmissions.[Part#] as PartNum
2) You can try to copy the [Transmissions] table to a new table that you create
that does not have the naming problems.
3) Export the [Transmissions] table to a CSV file and re-import it to a new
table (or possibly new database) without the naming problems.
Here is a link to a microsoft article that tells you why to avoid special characters in Access:
Big Bad Special Chars.
Hope that puts you on the right track. :)
Typically, this means that the field names are missing or misspelled.
Try running this to see:
SELECT * FROM Transmissions;
I've got this as the select part of my query:
SELECT cast(cast(exp_channel_titles.edit_date as char(14)) as datetime) AS Edit_Date
That takes data from a db in this format 20130501092128 and returns it in this format 2013-05-01 09:21:28
I can only assume it is some kind of magic as i don't fully understand how this works tbh.
But, i need to change the format of the date that it spits out to this format: %d/%m/%Y %k:%i:%s
I can honestly say i have no idea how to do this in that query, i've tried adding it as a param to datetime (is that even a mysql function?!?) but no joy and many other poor attempts that i wont go into.
If anyone can help, i'd be hugely grateful!
MySql automatically converts 20130501092128 to a date and time field, even if it is a VARCHAR or a INT, and you can just use this:
SELECT DATE_FORMAT(exp_channel_titles.edit_date, '%d/%m/%Y %k:%i:%s')
Please see fiddle here.
You can change output format using DATE_FORMAT() function from MySQL. Here is the documentation post about it.
https://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_date-format
You can change the output format into whatever format you want, but if you recieve that data into an application, modifies it and return that data to server (editing a row for example). Remember to reformat it into a valid date for MySQL.
If you dont know how to do it, just have to do this into your query:
SELECT DATE_FORMAT(cast(cast(exp_channel_titles.edit_date as char(14))
as datetime), '%e/%m/%Y %k:%i:%s') AS Edit_Date
In MySQL, I am trying to get difference between two timestamp value and storing the result in time column. But sometimes the result comes in 'hhh:mm:ss' format. While trying to access that column in Java using Result.getTime(), it is throwing error saying 'Bad format for time in column x'.
To get better idea, store the result of following query in time column and try to access this value in Java.
SELECT SEC_TO_TIME(ABS(TIMESTAMPDIFF(SECOND,'2013-01-26 19:03:48','2013-02-15 06:59:36'))) as 'RESULT';
What should I do to get result even if it has 'hhh:mm:ss' format (without any error)?
Thanks in advance.
I assume you run query and result set contain the result
String hourMinSec=resultset.getString("RESULT");
String[]result=hourMinSec.split(":");
int hour=Integer.parseInt(result[0]);
int min=Integer.parseInt(result[1]);
int second=Integer.parseInt(result[2]);
Expressing difference between two dates as date is meaningless i think. Just to answer your question if you want to create time you can use following
Time time =new Time(hour, min, second);
But i feel its meaningless.
You can't express the difference between two dates as another date. For example if you will got 31 days difference you can't say if it is 1 month or 1 month and 1 day.
You should create your own object to storage this data.
