Compare 2 dates MySQL Query

To compare two dates in MySQL , you can utilize comparison operators. These operators allow you to assess if one date is equal to, greater than, or less than another date. This comparison can be useful for filtering or sorting data based on date values, assisting in tasks like finding records within a specific date range or determining which date is earlier or later in your database.

In this example:

We first create two variables @date1 and @date2 and assign them the date values '2023-10-10' and '2023-10-10', respectively.
Then, we use a CASE statement to compare these variables.
The first WHEN condition checks if @date1 is equal to @date2.
The second WHEN condition checks if @date1 is greater than @date2.
The third WHEN condition checks if @date1 is smaller than @date2.
The ELSE condition is optional and provides a fall back in case none of the above conditions are met.
This query will return a result set with a column called comparison_result that contains 'Equal', 'Greater', 'Smaller', or 'Unknown' based on the comparison of the two date variables @date1 and @date2.
