It can calculate the number of days, hours, minutes, seconds, etc. between two dates. The syntax of the DATEDIFF function is as follows:<\/p>\n<pre class=\"post-pre\">DATEDIFF(unit,&nbsp;start_date,&nbsp;end_date)<\/pre>\n<p>The unit parameter specifies the time interval unit to be calculated, which can be one of the following values: year, quarter, month, day, hour, minute, second. The start_date and end_date parameters specify the start and end dates for the calculation. For example, to calculate the number of days between two dates, you can use the following statement:<\/p>\n<pre class=\"post-pre\">SELECT&nbsp;DATEDIFF(day,&nbsp;'2021-01-01',&nbsp;'2021-01-10');<\/pre>\n<p>This will return 9, indicating that there are 9 days between January 1, 2021 and January 10, 2021.
