Can anybody please tell me how to add a yesterday time stamp whenever my table get updated? Currently, it giving me today date instead yesterday date. Please see below picture.
I tired adding (CURRENT_TIMESTAMP, -1) on default/Expression. Did not work.

Thank you so much
You can use SUBDATE(CURRENT_DATE, INTERVAL 1 DAY) to subtract one day from today's date. For example:
SELECT *
FROM table_name
WHERE DATE(Date) = SUBDATE(CURRENT_DATE(), INTERVAL 1 DAY)
UPDATE
To update the value in the database, you can do the following:
UPDATE table_name
SET date = SUBDATE(CURRENT_DATE(), INTERVAL 1 DAY)
WHERE column = 'value'
I also needed the same, to update yesterday date whenever my table gets data. I have scheduled the following query, which worked perfectly for me.
I hope it will work for you also:
sql_yesterday_date = 'UPDATE tbl_dailytrade SET Date = subdate(current_date, 1) WHERE Date(date) = CURDATE()'

This is probably easy to do but I can't seem to get my head around it. I have a user table that has a next_payment DATETIME column which gets update every month. I would like a query to get all the users where their next_payment DATETIME is in one day from the current datetime.
I tried something like this but it also gets me users where their next_payment is due in like 15 minutes. Not good
SELECT * FROM users WHERE next_payment >= NOW() AND next_payment <= NOW() + INTERVAL 1 DAY
I also tried something like this but this doesn't work either as it gives me all users that had next_payment datetime like 2 or 3 months ago (Not good).
SELECT * FROM users WHERE next_payment <= NOW() + INTERVAL 1 DAY
Thanks in advance for any help
Need to Cast the datetime field to date so you can include all data within the period and use between
SELECT * FROM
users
WHERE
cast(next_payment as date)
between cast(NOW() as date)
AND cast(NOW() + INTERVAL 1 DAY as date)
DATEDIFF works fine in MySQL:
SELECT
*
FROM
users
WHERE
DATEDIFF(next_payment, NOW()) = 1
SQL Fiddle for this example.
I would use:
SELECT * FROM users
WHERE TIMESTAMPDIFF(HOUR,NOW(),next_payment) <= 24
I have a table 'schedule' and column 'travel_date'.
travel_date is having 'a predefined date' in that.
I want to alter that column with '5days' more.
like
UPDATE Schedule SET travel_date=''+5days ;
I used
UPDATE schedule SET travel_date = (travel_date+5);
It worked how ?
In MySQL you can do that with
UPDATE customer
SET register_date = DATE_ADD(register_date, INTERVAL 5 DAY)
Why would you want to add 5 days to every customers register date???
Are you sure this is what you want to do?
UPDATE customer SET [register_date] = DATE_ADD([register_date], INTERVAL 5 DAY)
If it is a datetime column, use the DATE_ADD() function:
UPDATE customer SET register_date = DATE_ADD(register_date, INTERVAL 5 DAY)
Using DATE_ADD()
You can use the DATE_ADD() function to handle adding a given interval (e.g. days, minutes, hours, etc.) to an existing date column:
UPDATE customer
SET register_date = DATE_ADD(register_date, INTERVAL 5 DAY)
Using Date Arithmetic
Alternatively, you can simply use date arithmetic as well, which is similar to your previous example:
UPDATE customer
SET register_date = register_date + INTERVAL 5 DAY
So, I need to reset the expiration dates for a bunch of coupon codes in our database. Our expirations dates are field "to_date" and are displayed as the following: to_date = '2013-04-14'
I need to set the to_date as 28 days after the from_date. So basically, something like this:
UPDATE salesrule
SET name = 'New coupon code', to_date = 'from_date + 28 days'
I know this would work for a simple int value, but I'm not sure how to do this give that the data displays as an actual date. I have no control over how the date itself displays, that's a built in Magento functionality.
I'm a big noob when it comes to MySQL, but I've done some research and I've found the format function: FORMAT(Now(),'YYYY-MM-DD') I have a feeling this may be the key... can someone point me in the right direction it terms of formatting or writing this command correctly? Thank you!
UPDATE salesrule
SET name = 'New coupon code', to_date = DATE_ADD(from_date, INTERVAL 28 DAY);
More info about the DATE_ADD() function here:
https://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_date-add
to_date = DATE_ADD(from_date, INTERVAL 28 DAY)
Check this question out, it does what you want.
You can use the DATE_ADD() function:
... WHERE DATE(DATE_ADD(eventdate, INTERVAL -1 DAY)) = CURRENT_DATE
It can also be used in the SELECT statement:
SELECT DATE_ADD('2010-05-11', INTERVAL 1 DAY) AS Tomorrow;
I have table tbl_dtcount. In that table there is one column for date.
Now I need to reduce one day for each and every rows in that date field. The date is beginning from 2012-05-19 to 2012-07-03. What is the MySQL update statement to perform this?
How about this.
Update tbl_dtcount
set mydate = DATE_SUB(mydate, INTERVAL 1 DAY)
where <conditions>;
UPDATE table_name
SET date_column = DATE_SUB('1998-01-02', INTERVAL 1 DAY)
....
see detail MySQL DATE_SUB
I can normally do this but it appears my brain is not functioning well right now and I'm missing something.
Every day via a cron job that is run at 1am, I want to get a count of rows that were inserted yesterday, and the date.
ie
SELECT DATE(added) as date, COUNT(*) FROM bookings WHERE added = DATE_SUB(NOW(), INTERVAL 1 DAY) GROUP BY date
'added' contains a timestamp ie '2011-04-18 12:31:31'
What am I getting wrong here? I know there are many rows added yesterday but my query is returning 0 results and no mysql_errors :(
Any ideas?
Please try
SELECT DATE(added) as yesterday, COUNT(*) FROM bookings WHERE DATE(added) = DATE(DATE_SUB(NOW(), INTERVAL 1 DAY)) GROUP BY yesterday
or perhaps
SELECT DATE(added) as yesterday, COUNT(*) FROM bookings WHERE DATE(added) = DATE_SUB(CURDATE(), INTERVAL 1 DAY) GROUP BY yesterday
Updated
Corrected the WHERE part.
well whatever NOW() is will return the time portion and unless they were added at exactly that time the day before they wont be counted.
So either use BETWEEN and specify time range, or format the date in your query to only match on the day month year components and not time
WHERE added = does only match exact NOW() - 1 DAY, you should select by a range instead.
