What does the NEXT_DAY(date, 'DAY') function return?

The NEXT_DAY(date, 'DAY') function returns the date of the specified day of the week that occurs after the input date. This function is particularly useful when you need to find the next occurrence of a certain day, such as the next Monday after a given date. For instance, if the date given is a Wednesday, and you use NEXT_DAY with 'Monday', the function will return the following Monday's date. This ability to reference specific days of the week enhances scheduling and planning functionalities within systems like NetSuite, allowing users to effectively manage their databases based on temporal data.

In contrast to other options, the function does not return the previous occurrence of the day, the first occurrence of the day in the month, or the last occurrence of that day in the month, which clarifies why the chosen answer is the correct interpretation of the function's output.
