Filtering MySQL Records Based on Today's Date
This guide demonstrates how to retrieve MySQL database records created today or in the future. We'll focus on efficient querying using the created
datetime field.
Optimal Query:
The most efficient method leverages the CURDATE()
function:
SELECT * FROM users WHERE created >= CURDATE();
Explanation:
CURDATE()
returns the current date without the time component. The query thus selects all records where the created
datetime value is on or after today's date, regardless of the time of creation.
Further Considerations:
To retrieve records created before today, use this query:
SELECT * FROM users WHERE created < CURDATE();
Note: MySQL's implicit type conversion allows for direct comparison between DATETIME
and DATE
values. For example:
SELECT NOW();
