Whether you're trying to calculate the number of days in a month or just need to know when the month ends, the solution is to use the LAST_DAY() function. This function takes a single argument, which is the date you want to find the last day of the month for.
For example, if you wanted to find the last day of the month for the date 2020-04-15, you would use the following query:
This query would return the result 2020-04-30, which is the last day of the month for the given date.
Let's look at a few examples of how this function can be used. Suppose you have a table called orders with the following data:
If you wanted to find the last day of the month for each of these dates, you would use the following query:
This query would return the results 2020-04-30, 2020-05-31, 2020-05-31, and 2020-06-30, which are the last days of the month for each of the given dates.
The LAST_DAY() function is supported by most major databases, including MySQL, PostgreSQL, and SQL Server. However, the syntax may vary slightly depending on the database you are using. For more information, check out the documentation for your particular database. 🤓
