How to write a query using the enrollment table to display the student number, section number, enroll date and final grade for all students with a created date of 14 December 1999.
This is what I think:
Select student_id, section_id, TO-CHAR(enroll_date, “dd-mon-yyyy hh24:mi;ss”)
FROM enrollment
Where trunc (create_date) = To_date (‘14-December-1999’, ‘dd-mon-yyyy’)
It does not work for me. Can someone assist me.
Thanks
Nazma

Your date formats should be in single quotes. Also, the data and the date format must match. So, either use December and Month or use dec and mon or use Dec and Mon. As well as specifying either the full or partial month name, both must also be upper case or lower case or initcap. See corrected code below:
SELECT student_id,
section_id,
TO-CHAR (enroll_date, 'dd-mon-yyyy hh24:mi:ss')
FROM enrollment
WHERE TRUNC (create_date) = TO_DATE ('14-Dec-1999', 'dd-Mon-yyyy')
/
In the future, please provide your table structure. For example, do this:
SQL> DESCRIBE enrollment
and copy the results onto your post. It would also help if you would provide the error message that you are receiving. It is important for you to start learning to figure out what the problem is, based on the error message, so that you can correct it yourself.
