Final answer:
In MySQL, the NOW() function is used to retrieve the current date and time. For the current date alone, use CURRENT_DATE or CURDATE(), and for the current time alone, use CURRENT_TIME or CURTIME().
Step-by-step explanation:
In MySQL, to find the current time or date, the function you would use is NOW(). This function returns the current date and time as a 'YYYY-MM-DD HH:MM:SS' format. For example, if you want to retrieve the current date and time, you would run the following SQL query: SELECT NOW();
If you are looking for only the current date, you would use the CURRENT_DATE or CURDATE() functions, and for the current time, you would use the CURRENT_TIME or CURTIME() functions.
