正解:E
The requirements specify that the data type must support date arithmetic, store a specific period (up to 10 years in terms of days), and be used for day-level calculations. The appropriate data type is:
* A: Incorrect. TIMESTAMP WITH TIMEZONE stores date and time with time zone information, which is not specifically needed for arithmetic or interval storage.
* B: Incorrect. TIMESTAMP stores date and time without considering time zone or providing interval arithmetic functionality.
* C: Incorrect. TIMESTAMP WITH LOCAL TIMEZONE adjusts the time zone but does not inherently support interval arithmetic or storage.
* D: Incorrect. INTERVAL YEAR TO MONTH is used for storing periods in terms of years and months, not suitable for daily calculations.
* E: Correct. INTERVAL DAY TO SECOND allows storage of periods in terms of days, hours, minutes, and seconds, meeting all the given requirements for precision and functionality in date arithmetic related to daily calculations.
