MySQL SYSDATE () returns the current date and time in YYYY-MM-DD HH:MM:SS or YYYYMMDDHHMMSS. SYSDATE() returns the time at which it executes. TIME_FORMAT() MySQL TIME_FORMAT() converts a time in a formatted string using the format specifiers. The SYSDATE function is used to retrieve the current database system time in Oracle and MySQL.
