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.. Play computer means to figure out the results yourself by evaluating the data rather than running the query.

Some students have encountered problems in putty because something has expired. If you encounter a problem, send me an email and I will ask IT to fix it.

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 #15
Week of May 7th
Tues and Thurs will be an open lab to get caught up from 9:30AM to 3:30PMish. Please come if you need help because Lindsey and I will both be available. Note that homework is due on May 10th. I will take a few things late (over the weekend).
You have a week to do the final. It is due by Fri, May 18 by midnight and you are required to also pass in the status sheet. Please send to the regular email address you use for homework and to priscilla.grocer@bristolcc.edu for backup.

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 third 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!

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.
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. The goal here is to look at the SQL and analyze the logic and figure out what you thing the results will be.
Week #2
Week of January 29th
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 I will also be around for a while Thurs afternoon after my 12:30 class. If you want help, please let me know.
These are the notes for this week.
More on maintaining an SQL table
SQL functions
More SQL functions

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 and I suggest selecting copy if the other does not work. 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 @.
Notes on creating the emp table in putty in response to a question
Inclass if statements (since online this semester it is an assignment.) 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. This helps you to analyze the problem and understand what is happening - again - please do not run these in Oracle.
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 January 22nd
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!
