Retrieve Records within a Date Range in MySQL
To select data from a MySQL table between a specified date and the current date, utilize the BETWEEN operator. The syntax is as follows:
SELECT * FROM table_name WHERE datetime_column BETWEEN 'start_date' AND CURDATE()
For instance, to retrieve data from January 1, 2009, to the current date, execute the following query:
SELECT * FROM table_name WHERE datetime_column BETWEEN '2009-01-01' AND CURDATE()
Alternatively, you can use the >= and <= operators:
SELECT * FROM table_name WHERE datetime_column >= '2009-01-01' AND datetime_column <= CURDATE()</p> <p><strong>Retrieving Day-to-Day Data</strong></p> <p>If you wish to obtain day-to-day data from January 1, 2009, you can employ a combination of COUNT() and BETWEEN:</p> <pre class="brush:php;toolbar:false">SELECT DATE(datetime_column) AS day, COUNT(*) AS count FROM table_name WHERE datetime_column BETWEEN '2009-01-01' AND CURDATE() GROUP BY day
This query will group the results by day and provide the count of records for each day within the specified date range.
