I have a table that has dates stored as text and not as a date_time. I want to select rows that happened today. I can hard code the date, but obvious I want to do it dynamically.
SELECT * FROM view WHERE anniversary LIKE '%09-07'
SELECT * FROM view WHERE anniversary LIKE '%' + DATE_FORMAT(now(), "%m-%d")
First, you should be storing dates as dates, not as strings.
But, if they are stored as strings, you can use a comparison like this:
where right(anniversary_datestring, 5) = str_to_date(curdate(), '%m-%d')
But, I recommend fixing your data. If the values are in the format YYYY-MM-DD, simply do:
alter table t modify column anniversary date;
The month and day operators can be used:
SELECT * from view WHERE MONTH(anniversary) = MONTH(NOW()) AND DAY(anniversary) = DAY(NOW())
if the column is of type varchar the STR_TO_DATE function can be used to turn it into a date:
SELECT * from view WHERE MONTH(STR_TO_DATE(anniversary,'%Y-%m-%d')) = MONTH(NOW()) AND DAY(STR_TO_DATE(anniversary,'%Y-%m-%d')) = DAY(NOW())
This should work,
convert string to date and check in where clause
SELECT * FROM view WHERE STR_TO_DATE(anniversary, '%d-%m-%Y') = CURDATE()

In Oracle I can query like:
Select * from Orders where trunc(createdDate) = trunc(sysdate)
and I get all orders created today.
How to do the same in MySql?
So far I can only find like currentdate() = '07-05-2017', I don't want to hard code the date.
Thank you,

The date() function returns the date part of any datetime value and curdate() function returns the current date, so no need to truncate its result:
... date(createdDate)=curdate()
I think a bit faster
Select *
FROM Orders
WHERE createdDate >= curdate();
Yes, you can use MySQL's DATE() function (along with NOW() function to get the current date). Here's the documentation.
Extracts the date part of the date or datetime expression expr.
Your query would be:
Select *
FROM Orders
WHERE DATE(createdDate) = DATE(NOW())
Update
As suggested by #Rahul, we can replace DATE(NOW()) with CURDATE() as it returns date without timestamp, e.g.:
Select *
FROM Orders
WHERE DATE(createdDate) = CURDATE()
I need to only SELECT data where the date field is yesterdays date. The only problem I'm having is that the data in the date field looks like the following 20160412 062815.000
I don't really care about the time, I just want to search dynamically for anything with yesterdays date. I've tried a multitude of CURDATE() -1 but I'm unsure how to just search the first 8 digits of the field.
Assuming the date value is stored as a string, and the first 8 characters are always the date in YYYYMMDD format, then you can use a query like this:
select *
from your_table
where your_column like concat(date_format(current_date() - interval 1 day,'%Y%m%d'),'%')
One advantage of this query is that it can leverage an index on your date field, unlike the other answers so far.
Format yesterday's date to a number and convert the date string also to a number.
select * from your_table
where date_format(curdate() - interval 1 day, '%Y%m%d') * 1 = date_col * 1

*1 is a math operation that forces MySQL to convert strings to a number.
you can use subdate(currentDate, 1)
select * from your_table
where subdate(currentDate, 1) = DATE(your_date)
I would like to ask if my Mysql statement is correct or not.. When I run this under mysql it does not return any error but I cannot retrieve the row for it. Here's my statement:
SELECT * FROM timekeeping WHERE createddate = NOW()
Here's what my table looks like
MySQL compare now() (only date, not time) with a datetime field
Try this:
SELECT * FROM timekeeping WHERE DATE(createddate) = DATE(NOW());
Most likely the createddate = NOW() is an exact time comparison , you are probably only interested in the year, month, day being the the same.
See here for details on how to do what you are trying to do:
http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html
Probably you want to search for today date.
Try this:
SELECT * FROM timekeeping WHERE DATE(createddate) = DATE(NOW());
now() includes the time. Given that your fields contain date AND time values, you'll only ever get a match if the date AND time are exact matches. You need to compare dates only:
... WHERE DATE(createddate) = CUR_DATE()
'2014-05-02' = '2014-05-02'
v.s.
... WHERE createddate = now()
'2014-05-02 22:14:00' = '2014-05-02 01:02:03'
My guess is that this isn't exactly what you want: NOW() function will return the exact timestamp for when the query is run, which means you are asking it for any records created at that exact moment in time.
You may want to try something more like:
SELECT * FROM timekeeping WHERE createddate = YOUR_DATE_CRITERIA
I have stored in the database in a varchar column the birthdays like this
dd/mm/YYYY
How can I select the birthday people from the current month directly from MySQL query??
And show using PHP
Thanks
First, do not store dates as a VARCHAR. Convert it to a DATE.
Once that's fixed, use one of the many MySQL date time functions:
SELECT * FROM users WHERE MONTH(birthday) = MONTH(NOW());
SELECT
*
FROM
yourtable
WHERE
MONTH(STR_TO_DATE(yourdatefield, '%d/%m/%Y')) = MONTH(NOW())
Assuming date is stored in %m/%d/%Y this format you can change this format according to your need.
and %m we are selecting only the month and comparing it to the current month MONTH(NOW()).
Replace DOB by your column and table by your table name
select * from table
where date_format(str_to_date(DOB, '%m/%d/%Y'), '%m') = MONTH(NOW());;
You should change your column type to DATE. e.g.
ALTER TABLE `people` CHANGE `dob` `dob` DATE NOT NULL;
By doing so you can then use the MySQL query date functions to filter the results.
SELECT * FROM people WHERE MONTH(dob) = MONTH(CURDATE()) AND YEAR(dob) = YEAR(CURDATE())
For Get User list whose birthday in current month in mysql if field datatype is date
$Toaday = '%'.date('-m-').'%';
$query = " select * from client where birth_date LIKE '$Toaday' ";
In your case declare $Today = '%'.date('/m/').'%';
As you used a VARCHAR field instead a DATE field,
you have to cast the value and then use the normal date functions. like
SELECT *
FROM table_name
WHERE MONTH(CAST(col_name AS DATE)) = MONTH(NOW());
I have store dates as a timestamp in tables so I create a query like this. and it's working fine.
don't use varchar for a date.
select first_name, last_name, date_format(FROM_UNIXTIME(`dateofbirth`), '%m/%d/%Y') as dob from users where date_format(FROM_UNIXTIME(`dateofbirth`), '%m') = MONTH(NOW())
I store standard date ( with this format: ('Y-m-d H:i:s') ) in mysql database, now i want to select records that match this standard date with current date, in other word i want to select the rows where standard_date field demonstrate today's date.
use DATE() to strip off time in the datetime column. CURDATE() returns the current date.
SELECT *
FROM tableName
WHERE DATE(standard_date) = CURDATE()
SQLFiddle Demo (DATE() vs without DATE())
Just use:
select * from mytable where date(standard_date) = curdate();
select * from tablename where date = CURDATE()
CURDATE() returns the current date.
If you use DATE type, use CURDATE() function -
SELECT * FROM table WHERE date_field = CURDATE()
If you use DATETIME type, use CURDATE() function and DATE() function to get date part from datetime value -
SELECT * FROM table WHERE DATE(date_time_field) = CURDATE()
