How to query records whose date and time are greater than or equal to today in MySQL?
Comparing a datetime to the current date is a common operation in MySQL. A common scenario is to retrieve records where a specific datetime field is greater than or equal to today.
Query records greater than or equal to today’s date and time
To do this, you can use the CURDATE()
function, which returns the current date. The following query demonstrates how:
<code class="language-sql">SELECT * FROM users WHERE created >= CURDATE();</code>
Explanation
This query selects all records from the users
table where the created
field (a datetime field) is greater than or equal to the current date.
Attention
It should be noted that this example assumes that the created
field only represents a date and does not contain any time component. If your datetime field contains both date and time, you may need to modify your query accordingly.
Other notes
Keep in mind that date-time comparisons can be complex. For example, if your created
field contains a timestamp that has both date and time information, you may experience different behavior when comparing it to the current date. In this case, you may want to consider using specific datetime functions or additional conditions to ensure accurate results.
