Oracle and SQL (CIS150/50)

Weekly Schedule

Essentially there are three ways for you to be able to work with Oracle:
1) Download the full version of Oracle and install it on your computer and work locally - that is what I have done
2) Work in the BCC labs with the BCC server installed Oracle
3) Access the BCC server installed Oracle from home using putty - there are instructions for that by Eric at my site.

Remember, all assignments including inclass assignments must be done by everyone - that includes online students and students who missed the class..

Schedule by weekInformation to cover
  Note that the audio and Smartboard presentations for each class are posted within a couple of days.
Please check the weekly schedule multiple times a week, I sometimes add things during the course of the week. You need to pass in the code you write and the output that is produced unless you are told otherwise. Sometimes this involves showing data that was written to a file/table. Please keep copies of all work you submit until you receive your final grade at the end of the semester.
Comment on how I want the assignment: You should take the commands you do in SQL and the results and paste them into a word document. It should be similiar to the way I prepared the notes. You then send me the word document. I do not want you to show the screen itself - they are really hard to read!
Week #12
Week of November 20th
Erik will be available Monday from 2 to 3 in K101 and Tuesday from 2 to 3:30 in K101 as well. I will be around some but mostly doing advisement. If you have not signed up for advisement, you should.
We will go back for a look at a few problems in the constraints assignment and then move on.
Catch up week!
Week #11
Week of November 13th
I will be out on Monday and Tuesday of this week. Erik will be available Monday from 11:30 to 2:30 in K101, Tuesday from 9:30 to 3:30 in K101 and Thursday from 4:00 to 6:00 in K105. These are open labs that anyone can attend.
We will go over exceptions and some of the things I skipped on Thursday.
Assignments:
Cursor/exception assignment
Week #10
Week of November 6th
Erik is available Tuesday, 2 - 3:30 in K101 and Thurs 2 - 5:30 starting in K101 and moving at some point to K105. I will be around doing advisement etc. Note that next week I will not be in on Monday or Tuesday so we are setting up open lab hours during the times I have classes and beyond. Everyone is invited to attend those labs.
We will continue with cursors and then back up to see some the the things under Notes and handouts that we did not cover yet.
Introduction to Cursors
Example 1 using cursors
Continuing example 1 using cursors
Another set of cursor examples
Covers: Cursors in PL/SQL, cursor example and continuation of first cursor example
      Separate speaker notes for Cursors in PL/SQL, cursor example and continuation of first cursor example
Covers: Another set of cursor exampes
      Separate speaker notes for Another set of cursor examples
If we get through these, we will go and check on some of the things we skilled over.
Woops... I pasted under week #11 rather than here under week #10. It is correct now!
Examples we are going over in class:
payprog.sql
data.txt Data layout for studentchk.sql
studentchk.sql
createdonor.sql Script to create donor
donorcursor1.sql
donorcursor2.sql
donorcursor3.sql
decodecursor1.sql
Assignments:
Use cursors to solve these problems.
First Problem:Write a PL/SQL program to accomplish the following: Using the sample emp database, give everyone in dept 10 a 5% raise, everyone in dept 20 a 7.5% raise, everyone in department dept 30 a 10% raise. Do this using a simple IF...ELSE and a loop.
Second Problem:Modify the problem in #1 to meet the following criteria: IF dept is 10 and the salary is greater than 2000 give a 6% raise otherwise give a 7% raise. IF dept is 20 and the salary is greater than 2500 give a 5% raise otherwise give a 5.5% raise. IF dept is 30 and the salary is greater than 1000 give a 7% raise otherwise give a 6.5% raise.
Third Problem: Set up an inventory table and a transaction table that has sales, returns, and purchases (the transaction table should have a code with S for sales, R for returns and P for purchases). Create scripts to create and insert data into these tables.
Fourth Problem: Using the tables you created in the fourth problem, process the transactions and determine the impact on inventory. Display information that gives the original inventory and the inventory after the sales, returns and purchases have been processed. You need to use cursors. Check back!
Week #9
Week of October 30th
Erik is available Monday 2-3 in K101, Tues 2 - 3:30 in K101 and Thurs 4-6 in K105.
We will continue with the PL/SQL that is listed under last week and then... Check back!
Assignments:
Oracle Loop Assignment
Oracle PL/SQL Intro Quiz - Start in class
In class we will start a cursor program. I want you to write a script that will handle the inven table and the department table. The script should accumulate the onhand for departments and write to a new table where you will store the dept, the department name and the total of the onhand. I would also like you to use the dbms lines to show the processing that happens. Everyone needs to turn in this script including the dbms output and a listing of what is on the new table. Please pass in by Tuesday since I am going over it in class.
Week #8
Week of October 23rd
Erik is available in K101 Monday 2-3, Tues 2:3:30 and Thurs 4-6 (in K105). I will be in and out.
We will wind up SQL this week and start PL/SQL, so please check back!
This week, I am going to look at The Introduction to PL/SQL (the beginning part), skip for a while the More examples of input/output procedures (we will go back to them) and work on Introduction to IF statements. The things below will probably be partially done and the rest we will look at next week.

More information on joins
Some interesting examples
Questions about work with SQL on a home installed version. To highlight, copy and paste SQL commands and output when you are using a window that works like a command prompt window. Right click on the top border around the command window, select edit and then mark to highlight. Do the same right click edit and select copy. Then you can paste in a document.
Assignments:
Function assignment
In problem #1 just to be clear, I want you to take a name that has been written with the slash separator in the format last/first m and flip it so it has first m last using Oracle functions. Specifically it can be done using substr and instr.
We will start this quiz in class.
Oracle quiz I am interested in having you play computer - I do not want you to use the computer to get the results. You can check your results if you want to, but please do it on your own.
Week #2
Week of September 11th
Please do not change any of the passwords we have given you. I need to be able to get to your site as does the IT staff if there is a problem. I will be available for help Monday at 10:00 in my office K112 and Erik will have lab time at 2 on Tuesday and Thursday in K101. I will try to be there at least part of the time.
We will review the conditions note from last Thursday.
These are the notes that I will attempt to get through this week.
More on maintaining an SQL table
SQL functions
More SQL functions
Group SQL functions
I may go further, so do check back.
You should also look at the accompanying PowerPoint presentations:
More on maintaining an SQL table

Always check back and see how we are doing!
Assignments:
Here is a script to create the emp table:
Script to create emp table (createemp.sql)
You can enter edit createemp.sql or another name at the SQL prompt. It will go into the editor and ask if you want to create a new script. Enter yes and paste the script in and save it. Return to the prompt and enter @ createemp.sql and it should run and create the table for you.
If you are using putty, remember to have the script text in notepad and highlight it. When you go into the editor the right click will paste it or you can uses shift + ins to paste. You can then write and exit. Back at the SQL prompt is where you run it with the @.
Inclass if statements (must be passed in by everyone) I want you to play computer and show me the output you think would be generated as opposed to running the query and letting Oracle give you the answer.
Second SQL assignment
Quiz 1
I am hoping your have already created a table that you can use for this quiz. If not you need to create one. I would suggest you create one that you can use with assignments from week 1 or week 2. Note that you need to show me the SQL and the results on all of the quiz questions.
Check back!
Week #1
Week of September 4th
I am available after 2 on Tuesday or Thursday at 1:45 if you have questions. Check my office K-112 or the classroom K-101 or the central K Buildign lab.
I recommend one of the text books in the syllabus, but a textbook is not required. There is enough material on the web and in my notes that I decided to make the book a recommendation. Please note that many students have found it useful to have a copy of the text. I do recommend that you get one of these books or another book dealing with Oracle SQL (we are using version 11g or 12c this semester) as a reference. We will not do chapter by chapter coverage, the text gives you additional information on topics and a reference if you have questions.
ional database information
LOGIN information:
You need to decide if you want to download Oracle, use the BCC labs or login from home using Putty.
Note that there is a reference to help you download and instal under Using Oracle: Installation and login.
Downloading Be very careful when you install, Oracle leaves a lot of footprints that makes reinstalling very difficult.
You should have received the login information you need for this course. If not, let me know.
PuTTY is available in the labs. Two sites that can be used to download PuTTY are:
PuTTY
PuTTY
Using Putty (copy and paste)
Basic steps to login to putty and get to Oracle:
1) Start putty and put in the hostname as cisweb.bristolcc.edu
2) At the login screen enter your username and your Linux password.
3) When you see that you are at cisweb, enter sqlplus12c.sh
4) You then connect to Oracle and need to enter your username and Oracle password
5) You should see the SQL prompt
Now you can create a table. Note that after you create tables, to see existing tables select table_name from user_tables.
Accompanying step-by-step notes
First we will focus on getting into Oracle and then these are the notes that we will start to cover this week:
Introduction to SQL in Oracle
Create a table in SQL
SQL Conditions
These are the accompanying presentations:
Presentations:
Introduction to SQL in Oracle
      Separate speaker notes for Introduction to SQL in Oracle
Create a table in SQL
      Separate speaker notes for Create a table in SQL
SQL Conditions
      Separate speaker notes for SQL Conditions
NOTES: Note: You can use the committ command to make sure your work gets saved.
Copy from SQLPlus so you can paste it onto the document you are submitting as your assignent
Assignments:
I strongly urge you to do the COMMIT; after the table is created.
Oracle assignment on introductory material (html)
Oracle assignment on introductory material (doc)
Comment on how I want the assignment: You should take the commands you do in SQL and the results and paste them into a word document. It should be similiar to the way I prepared the notes. You then send me the word document. I do not want you to show the screen itself or pictures of the screen - they are really hard to read!
