How to Select Data from Today's Date Using the `signup_date` DateTime Field in MySQL?

MySQL Query to Select Data from Today Based on Datetime

In MySQL, you can retrieve data from a specific date by utilizing the DATE() and CURDATE() functions. The DATE() function extracts the date component from a datetime value, while CURDATE() returns the current system date.

Problem

A user needs to select data from a table where the datetime field signup_date matches today's date, but their initial query using CURDATE() and DATE_FORMAT() is not working.

Solution

To correctly compare a datetime value to today's date, you should use:

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE DATE(users.signup_date) = CURDATE()

In the modified query:

• DATE(users.signup_date) extracts only the date part of the signup_date datetime value.
• CURDATE() provides the current system date.

By comparing the date components of signup_date and CURDATE(), you can filter out records that do not match today's date.
