To answer this question, we need to understand the different DATETIME data types that can be used when specifying column definitions. Let's go through each option to understand which ones are correct:
Option A) TIMESTAMP - This option is correct. TIMESTAMP is a DATETIME data type that represents a date and time value.
Option B) INTERVAL MONTH TO DAY - This option is incorrect. INTERVAL MONTH TO DAY is not a DATETIME data type. It is a data type used to represent an interval of time in terms of months and days.
Option C) INTERVAL DAY TO SECOND - This option is correct. INTERVAL DAY TO SECOND is a DATETIME data type used to represent an interval of time in terms of days, hours, minutes, and seconds.
Option D) INTERVAL YEAR TO MONTH - This option is correct. INTERVAL YEAR TO MONTH is a DATETIME data type used to represent an interval of time in terms of years and months.
Option E) TIMESTAMP WITH DATABASE TIMEZONE - This option is incorrect. TIMESTAMP WITH DATABASE TIMEZONE is not a DATETIME data type. It is a TIMESTAMP data type that includes the database time zone.
The correct answers are A) TIMESTAMP, C) INTERVAL DAY TO SECOND, and D) INTERVAL YEAR TO MONTH. These three options are correct because they are DATETIME data types that can be used when specifying column definitions.
