I need to find upcoming birthday from database table name users and column name u_bday where u_bday is in varchar format.
i tried this but not work for me help.
$sql=" SELECT `f_name`,`u_bday` FROM `users`
WHERE DATE_ADD(`u_bday`, INTERVAL YEAR(CURDATE())-YEAR(`u_bday`)+
IF(DAYOFYEAR(CURDATE()) > DAYOFYEAR(u_bday),1,0) YEAR)
BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 7 DAY)";
what should i do???
use this function to convert your varcher column to date format
str_to_date( fieldname, '%Y-%m-%d')
You can use date_diff function and query could be somthing like below
SELECT `f_name`,`u_bday` FROM `users`
WHERE DATE_DIFF(`u_bday`, now()) > 1
ORDER BY u_bday asc;

I have tried to filter records but with the use of now function as given below
select * from table where date>= DATE_SUB( NOW( ) ,INTERVAL 90 DAY )
What I need is a select statement that can filter its records for a week or month from the current date but without using NOW() function
if you are using java you could make use of the following code
String timeStamp = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(Calendar.getInstance().getTime());
or you could use curdate() of mysql
Since I found it hard to understand the question I provide the following possibilities:
Try for all dates in a week from now:
SELECT * FROM table
WHERE date BETWEEN CURDATE() AND DATE_ADD(CURDATE() ,INTERVAL 1 WEEK)
and for all dates in a month from now:
SELECT * FROM table
WHERE date BETWEEN CURDATE() AND DATE_ADD(CURDATE() ,INTERVAL 1 MONTH)
If you are looking for all dates of the current month use
SELECT * FROM table
WHERE MONTH(date)=MONTH(CURDATE()) AND YEAR(date)=YEAR(CURDATE())
or for all dates of the current week use
SELECT * FROM table
WHERE WEEK(date)=WEEK(CURDATE()) AND YEAR(date)=YEAR(CURDATE())
I want to fetch data of last 1 hour from mySQL database. I can certainly do it in java after results have been fetched but i don't want to unnecessarily put load on application. Please help.
select * from tb_data
where createdtime > ADDDATE(NOW(), INTERVAL -1 HOUR)
If the column is of type DATE you can use the DATE_SUB function, which substracts a given time interval from a DATE.
SELECT * FROM [table] WHERE [date_column] > DATE_SUB(NOW(), INTERVAL 1 HOUR)
Documentation
select * from yourtable where created_at between NOW() and date_sub(NOW() , interval 1 HOUR)
I am trying to only show records where "DateDue" is within the last year. The trouble is my date is in the format of Varchar(10) as a result of my data feeds coming into my database on intervals from a vendor. Obviously, the dates are not being filtered properly using this query. Is it possible to convert this (temporarily for sake of comparing the date range) to the proper date data type for use in the query, but not permanently alter the type for that column?
SELECT `DocNum`, `DateDue`
FROM `prod_po_list`
WHERE `DateDue` BETWEEN (DATE_FORMAT(curdate( ) - INTERVAL 365 DAY , '%m/%d/%Y' ))
AND DATE_FORMAT( CURDATE( ) , '%m/%d/%Y' )
Are you looking for something like this?
SELECT DocNum, DateDue
FROM prod_po_list
WHERE STR_TO_DATE(DateDue, '%m/%d/%Y')
BETWEEN DATE_SUB(CURDATE(), INTERVAL 365 DAY)
AND CURDATE()
If you have index on date column this will be helpful
SELECT DocNum, DateDue
FROM prod_po_list
WHERE DateDue >= DATE_SUB(CURDATE(), INTERVAL 365 DAY)
AND DateDue <= CURDATE()
I would like to rows that have only been entered in the last 1 day.
I have a date column which stores YYYY-MM-DD, and I allow the user to send a date that they want to look at in this format yyymmdd how can I use this data to limit it to the previous day only?
I would imagine it is something to do with the BETWEEN keyword but I cant figure it out.
SELECT * from TABLE_NAME WHERE ROW_DATE BETWEEN '2011-03-20' AND '2011-03-21'
This query:
SELECT *
FROM mytable
WHERE mydate >= STR_TO_DATE('110321', '%y%m%d') - INTERVAL 1 DAY
AND mydate < STR_TO_DATE('110321', '%y%m%d')
will return all records for Mar 20, 2011
From the MySQL manual (here):
SELECT something FROM tbl_name WHERE DATE_SUB(CURDATE(), INTERVAL 1 DAY) <= date_col;
SELECT * FROM YourTable WHERE date_column = DATE_ADD(CURDATE(), INTERVAL -1 DAY)
This returns all rows for today and yesterday.
I keep a record of logins in a table. I have columns for id, ip, date and time. From that record of logins I wanna fetch logins made only in the last hour.
I'm sweeping through the MySQL docs on time and date functions, but I just can't seem to combine them correctly.
Can somebody help me?
Make use of the DATE_SUB() and NOW() functions:
select count(*) as cnt
from log
where date >= DATE_SUB(NOW(),INTERVAL 1 HOUR);
Hope it helps you : )
If you want to implement this into a cronjob, you need to specify the start and end.
For example, at 2pm, if you want to get the data for the past hour from 13:00:00 until 13:59:59, here's how to do it:
dateField BETWEEN
DATE_FORMAT(DATE_SUB(NOW(), INTERVAL 1 HOUR), '%Y-%m-%d %H:00:00')
AND
DATE_FORMAT(DATE_SUB(NOW(), INTERVAL 1 HOUR), '%Y-%m-%d %H:59:59')
it can be done easily using
select count(*) from logins where datetime>= NOW()- INTERVAL 1 HOUR
I recommend have one datetime column instead of date and time columns.
Suppose you have a datetime column called last_login:
SELECT id, ip_address, last_login
FROM mytable
WHERE last_login >= DATE_SUB(NOW(), interval 1 hour);
without the specifics, I think Date_Add() would work.. by adding to your where clause an add of NOW negative hours
(or Date_Sub() )
You can also use CURDATE()function
SELECT
count(*) AS TotalCount
FROM
tblName
WHERE
datetime >= DATE_SUB(CURDATE(), INTERVAL 1 HOUR)
