Selecting MySQL Records with a Date Equal to Today
When working with a MySQL database, you may encounter the need to retrieve records based on a specific date, particularly when assessing data for the current day. This article provides a solution to accomplish this task.
To select records with a date column equal to today, where the data type is datetime, follow the steps below:
- Use the CURDATE() Function: Determine the current date using the CURDATE() function. This function returns a value representing today's date in the format 'YYYY-MM-DD'.
- Extract the Date Component: Extract the date component from the datetime column using the DATE() function. This function removes the time portion, leaving only the date.
- Compare the Date Components: Compose your SELECT statement to compare the date component of the datetime column to the current date obtained from CURDATE(). The following query will achieve this:
SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') FROM users WHERE DATE(users.signup_date) = CURDATE()
This query selects the id and formatted signup date for users whose signup date matches today's date. If you wish to select only the id, you can modify the query as follows:
SELECT id FROM users WHERE DATE(signup_date) = CURDATE()
By implementing these steps, you can efficiently retrieve records that meet the specified date criteria from your MySQL database. This technique can be applied to any table containing a datetime or date column where you need to filter data based on today's date.
The above is the detailed content of How to Select MySQL Records with a Date Equal to Today?. For more information, please follow other related articles on the PHP Chinese website!

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
