The QUARTER function returns an integer between 1 and 4 that represents the quarter of the year in which the date resides. For example, any dates in January, February, or March will return the integer 1.
If expression is a character or graphic string, it must not be a CLOB or DBCLOB and its value must be a valid string representation of a date or timestamp. For the valid formats of string representations of dates and timestamps, see String representations of datetime values.
The result of the function is a large integer. If the argument can be null, the result can be null; if the argument is null, the result is the null value.
SELECT QUARTER(PRENDATE) INTO :QUART FROM PROJECT WHERE PROJNO = 'PL2100'Results in QUART being set to 3.
