Project Information
- Term Project Descriptions:
PDF
- Testing Environment:
The Java version on Pitt's unixs machine is "1.6.0_37". We will test
your projects only on pitt unixs machine. Although you are free to
develop your project in a different environment, you should make sure
your code works in the Pitt unixs environment before submitting your
project.
- Demo Program
To help you started, see Recitation 8. You can also downlod and execute the following demo Java program:
JavaDemo.java. The JavaDemo has all
the code and an example embedded in it. You can use this program as a skeleton
for your project.
- dayofweek
Unfortunatelly, dayofweek() is not working as advertised in the
latest version of the Oracle manual. This applies to both sqlplus
and Embedded SQL. Instead please use "to_char()". You can read
the Oracle SQL Reference manual for details (pg 3-52).
Here's a quick overview:
select to_char(mydate, 'DY') from .....
--> returns "sun", "mon", "tue", "wed", "thu", "fri", or "sat".
select to_char(mydate, 'D') from .....
--> returns 1-7 (with 1 being sunday)
* mydate must be a date attribute from a relation.
If instead of a date type, you have a string that you want to figure
out which day of the week it falls on, you need to also use to_date().
For example:
select to_char(to_date('19-apr-2003'), 'DY') from .....
--> returns "sat"
select to_char(to_date('19-apr-2003'), 'D') from .....
--> returns 7
