I've been trying to compare a date (yyyy-mm-dd) to sequelize.literal('CURRENT_TIMESTAMP') as shown below:
dataagendado: {
[Op.gte]: sequelize.literal('CURRENT_TIMESTAMP')
}
This works for greater than cases but not when the value of dataagendado is equal to today's date. I believe I need to format the CURRENT_TIMESTAMP data. I've been trying to find an answer but all I get are formatting for when a column is created, which doesn't seem to be applicable inside a SELECT query. I've also tried sequelize.fn('NOW') and formatting it but got no luck.
Am I even on the right track? Any help would be greatly appreciated.
Disclaimer: I'm assuming you are using Postgres as the underlying database. If it's not the case, please post your database engine.
You are using sequelize.literal('CURRENT_TIMESTAMP') which resolves in Postgres to NOW(). The NOW() function returns the timestamp with the current time. If you are comparing your date without the timestamp against a date with a timestamp that shouldn't work.
You could use something like this:
dataagendado: {
[Op.gte]: sequelize.literal('now()::Date')
}
In SQL the following happens:
SELECT NOW() => 2021-03-31T07:39:24.518Z
SELECT NOW()::Date => 2021-03-31T00:00:00.000Z
Thanks to staaar's answer I got enough insight to realize that I should be looking for a function in the database's documentation and not in Sequelize's documentation or threads. I'm using MySql as the database so the current date function I should be using looks like this:
dataagendado: {
[Op.lte]: sequelize.literal('CURDATE()')
}
Here's the official documentation, maybe look for something similar in your database's documentation. Best of luck!
Thanks again to user staaar!

I have a database table containing dates
(`date` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00').
I'm using MySQL. From the program sometimes data is passed without the date to the database. So, the date value is auto assigned to 0000-00-00 00:00:00
when the table data is called with the date column it gives error
...'0000-00-00 00:00:00' can not be represented as java.sql.Timestamp.......
I tried to pass null value to the date when inserting data, but it gets assign to the current time.
Is there any way I can get the ResultSet without changing the table structure?
You can use this JDBC URL directly in your data source configuration:
jdbc:mysql://yourserver:3306/yourdatabase?zeroDateTimeBehavior=convertToNull
Whether or not the "date" '0000-00-00" is a valid "date" is irrelevant to the question.
"Just change the database" is seldom a viable solution.
Facts:
MySQL allows a date with the value of zeros.
This "feature" enjoys widespread use with other languages.
So, if I "just change the database", thousands of lines of PHP code will break.
Java programmers need to accept the MySQL zero-date and they need to put a zero date back into the database, when other languages rely on this "feature".
A programmer connecting to MySQL needs to handle null and 0000-00-00 as well as valid dates. Changing 0000-00-00 to null is not a viable option, because then you can no longer determine if the date was expected to be 0000-00-00 for writing back to the database.
For 0000-00-00, I suggest checking the date value as a string, then changing it to ("y",1), or ("yyyy-MM-dd",0001-01-01), or into any invalid MySQL date (less than year 1000, iirc). MySQL has another "feature": low dates are automatically converted to 0000-00-00.
I realize my suggestion is a kludge. But so is MySQL's date handling.
And two kludges don't make it right. The fact of the matter is, many programmers will have to handle MySQL zero-dates forever.
Append the following statement to the JDBC-mysql protocol:
?zeroDateTimeBehavior=convertToNull&autoReconnect=true&characterEncoding=UTF-8&characterSetResults=UTF-8
for example:
jdbc:mysql://localhost/infra?zeroDateTimeBehavior=convertToNull&autoReconnect=true&characterEncoding=UTF-8&characterSetResults=UTF-8
Instead of using fake dates like 0000-00-00 00:00:00 or 0001-01-01 00:00:00 (the latter should be accepted as it is a valid date), change your database schema, to allow NULL values.
ALTER TABLE table_name MODIFY COLUMN date TIMESTAMP NULL
As an exteme turnaround, when you cannot do an alter to your date column or to update the values, or while these modifications take place, you can do a select using a case/when.
SELECT CASE ModificationDate WHEN '0000-00-00 00:00:00' THEN '1970-01-01 01:00:00' ELSE ModificationDate END AS ModificationDate FROM Project WHERE projectId=1;
you can try like This
ArrayList<String> dtlst = new ArrayList<String>();
String qry1 = "select dt_tracker from gs";
Statement prepst = conn.createStatement();
ResultSet rst = prepst.executeQuery(qry1);
while(rst.next())
{
String dt = "";
try
{
dt = rst.getDate("dt_tracker")+" "+rst.getTime("dt_tracker");
}
catch(Exception e)
{
dt = "0000-00-00 00:00:00";
}
dtlst.add(dt);
}
I wrestled with this problem and implemented the URL concatenation solution contributed by #Kushan in the accepted answer above. It worked in my local MySql instance. But when I deployed my Play/Scala app to Heroku it no longer would work. Heroku also concatenates several args to the DB URL that they provide users, and this solution, because of Heroku's use concatenation of "?" before their own set of args, will not work. However I found a different solution which seems to work equally well.
SET sql_mode = 'NO_ZERO_DATE';
I put this in my table descriptions and it solved the problem of
'0000-00-00 00:00:00' can not be represented as java.sql.Timestamp
There was no year 0000 and there is no month 00 or day 00. I suggest you try
0001-01-01 00:00:00
While a year 0 has been defined in some standards, it is more likely to be confusing than useful IMHO.
just cast the field as char
Eg: cast(updatedate) as char as updatedate
I know this is going to be a late answer, however here is the most correct answer.
In MySQL database, change your timestamp default value into CURRENT_TIMESTAMP. If you have old records with the fake value, you will have to manually fix them.
You can remove the "not null" property from your column in mysql table if not necessary. when you remove "not null" property no need for "0000-00-00 00:00:00" conversion and problem is gone.
At least worked for me.
I believe this is help full for who are getting this below Exception on to pumping data through logstash

I have a table that includes dates, I'm trying to check if a date I have falls between the dates in the table. My query is working, but it doesn't return anything. This seems like it should be very simple, but I can't wrap my head around it.
SQL query looks like this:
SELECT id FROM table
WHERE
(this_date) between (beginning_date_from_table) and (end_date_from_table)
The dates are generated dynamically in my script so I can ascertain if what I'm passing into it falls between the beginning and end dates in my table. I don't need any specific data from the table, just a boolean telling me whether the date is between the beginning and end dates or not.
You are looking for EXISTS:
SELECT
EXISTS(
SELECT id FROM table
WHERE
(this_date) between (beginning_date_from_table) and (end_date_from_table)
) AS hasValue
Hope this helps,
Check your MySQL server's date format and your generated date format.
MySQL date format is like that: '2019-01-30 18:19:52'
Also you can try change
(beginning_date_from_table) and (end_date_from_table)
to
(end_date_from_table) and (beginning_date_from_table)
Check: How do I query between two dates using MySQL?
I phrased the question slightly wrong, in that I was trying to return the result of a conditional. Once I realised how to ask google the right thing, I quickly came up with this solution:
SELECT (CASE WHEN this_date BETWEEN beginning_date AND end_date THEN 1 ELSE 0 END) AS date_result
Thanks to the other people who answered, your input put my thinking on the right track.
I want to see the working of MySQL functions FROM_UNIXTIME() and UNIX_TIMESTAMP() by providing the parameters to them myself in CLI, something like this:
SELECT UNIX_TIMESTAMP(1459460268);
without having to insert these custom values in a table first and then selecting them to see the output.
Thank you for your time :)
UNIX_TIMESTAMP function accepts a date and you are giving it UNIX TIMESTAMP. You can simply run this in MySQL CLI and get the results:
SELECT UNIX_TIMESTAMP("2016-04-01 03:07:48");
SELECT FROM_UNIXTIME(1459460268);
SELECT UNIX_TIMESTAMP();
The last one will return you the current UNIX TIMESTAMP.
Happy coding!
I need help on calculating my time difference. I search on the forum but not what I need. Here is the code I am using:-
(convert(varchar(10),([RT_Phase_Time])-(convert(time,'00:30:00'))))
So I [RT_Phase_Time] is in this format 'hh:mm:ss'. I am trying to get the difference between ([RT_Phase_Time] - '00:30:00'). Please help!
In MySQL you can easily do that with TIMEDIFF().
TIMEDIFF('22:00:00','00:30:00');
-- Returns '21:30:00'
http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_timediff
Try something like this, check the BOL for datediff to convert to other values:
declare #rt_phase_time time
set #rt_phase_time = '12:30:30'
select datediff(ss,cast('00:30:00' as time),#rt_phase_time)
In my application am using JPA entity manager to persist data/fetch data.
em.executeQuery("select * from file_calender_mapping where start_date between :start and :end");
em.setParameter("start",startDate)//startDate is an date object
em.setParameter("end",endDate)//endDate is an date object
List fmlist=em.execute();
The proble is just like this,
"select * from file_calender_mapping where start_date between start and end"
when am passing some date as start= "2011-08-03 05:08:00",and end="2011-08-04 06:08:00"
then the mysql return one row having the start time ="2011-08-03 05:30:00",its good,But
when my application executing such query it dose not returning any row.Actually what i have seen that my application returning value for two different date,but not for same date different time,thats the main problem.
One another thing is my "start" field for Table "file_calender_mapping" datatype is "timestamp".
So what i was thinking that ther may be some problem on JPA/Hibernate
You can try to specify the exact types of parameters as follows:
em.setParameter("start", startDate, TemporalType.TIMESTAMP);
em.setParameter("end",endDate, TemporalType.TIMESTAMP);
I have the strong feeling that you're confusing EntityManager.createQuery() with EntityManager.createNativeQuery() and you're somehow capturing all the exceptions, which somehow makes you don't receive anything back.
I'm assuming that, because I don't think you have a class named file_calender_mapping.
edit
The documentation will explain it better than I do, but a JPA QL query is transformed to the navite sql of the DB using the mapping, while a native query is send as it's to the DB.
Again, I suggest you to read the documentation, it's quite useful.
