| Schedule by week | Information 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. Play computer means to figure out the results yourself by evaluating the data rather than running the query. 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! | |
| HELP schedule | To contact Joe use moocowoftech@gmail.com. He will be available from 9-2 on Mon thru Fri for open labs at this address:
Collaborate For hours outside of that he will be using Microsoft Teams which is available to you through Office 365. Send him an email from your bcc account with the classes you want to connect to and you will get a link to join. Here is a brief run down on how it works and what to expect: Microsoft Teams overview There is access to WiFi from your car under the solar canopies on the Fall River Campus. |
| Final | Final Exam Due Thursday, May 14, 2020 This is an open notes/open book final. The only person you should ask questions of is me. The final will take more than 2 hours so you should plan accordingly. Essentially you will have to do research, look up answers and problem solve during the week you are taking the final as opposed to studying for the final and then taking it. The status sheet posted below is a requirement. I do not correct finals unless I have a status sheet. The status sheet is my way of making sure that your records match with my records. If I do not have something you say you passed in and it will effect your grade, I will contact you. |
| Week #15 Week of May 4th |
Catch up week! I will be posting information about the final this week. You will have a week to do it. Required status sheet |

| Week #10 Week of March 30th |
I will give extra credit to anyone who goes to the Collaborate site (see link in HELP above) and either works with Joe on something
they need help with or shows him something they have done for the course. Send me an email and let me know what you did. Actually this
applies to doing something with Joe using Teams app as well. Continuing with cursor information we started last week. 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. Continuing example 1 using cursors Another set of cursor examples Covers: Another set of cursor exampes Separate speaker notes for Another set of cursor examples Examples we are going over in class: payprog.sql payprog1.sql payprog2.sql data.txt Data layout for studentchk.sql studentchk.sql createdonor.sql Script to create donor donorcursor1.sql donorcursor2.sql donorcursor3.sql decodecursor1.sql The plan for Thursday was: Assignments: To get used to cursors, I want you to start with this 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. Next assignment: 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. Fifth Problem: I want you to redo this program so that the EXIT does not come in the middle of code but rather at the bottom. Do the second version of the program on this example sheet: Example |
| Week #9 Week of March 23rd |
Officially there are no classes and no assignments this week. However, I decided to post this weeks work anyway so you can get
started on it if you choose to. I feel that choosing to do the work this week will spread the work out better and make the end of
the semester easier no matter how it is handled. I will keep putting out the work for each week as originally planned to give you
more flexibility. Late points will not be taken. Again, it is your choice whether you do the work this week or leave it for next week. We will look at the loops and data manipulation in PL/SQL that are listed under last week. Then we will continue on with PL/SQL. Returned to finish this handout: Introduction to PL/SQL Note the accompanying Powerpoint is listed on week #8. Joe's introduction to loops again Then started cursors: Introduction to Cursors Example 1 using cursors 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 Assignments: Oracle Loop Assignment Oracle PL/SQL Intro Quiz |
| Week #8 Week of March 9th |
I will not be on campus Thursday, March 12th. The group
advising session is also cancelled, we will reschedule if possible. We will start PL/SQL this week. Joe's introduction to loops 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. Introduction to PL/SQL Introduction to IF statements More on PL/SQL IF statements Introduction to loops Data manipulation in PL/SQL - introduction With the accompanying PowerPoint presentations: Introduction to PL/SQL Separate speaker notes for Introduction to PL/SQL PL/SQL - Using IF statements Separate speaker notes for PL/SQL - Using IF statements More on PL/SQL IF statements Separate speaker notes for More on PL/SQL IF statements Introduction to loops Introduction to loops Separate speaker notes for Introduction to loops Data manipulation in PL/SQL - introduction Separate speaker notes on Data manipulation in PL/SQL - introduction Assignments: IF assignment |

Examples
Solution A few more examples And still more examples We will also start to look at constraints, keys, indexes. First we will look at a practical example of working with keys and constraints. Then we will look at other things you can do and at the theory. Third normal form Keys and constraints example Indexes in Oracle - An introduction Also please look at the accompanying presentations: Indexes in Oracle - An Introduction Separate speaker notes for Indexes in Oracle - An Introduction Assignments: Oracle Key Example(this is a check off assignment) I want you to go through this example and do what I did so you follow and understand the concepts. Check back! |
| Week #5 Week of February 17th |
I am going to look at subqueries a little more after you have tried the assignment from last week. So, we are going to move on
and cycle back as needed. Realistically I think what I have posted will carry over into next week, but we will see. This is an example that you might find helpful (repeated week 6): Examples Solution A few more examples We started looking at variables and got through Using Input Variables and some of more on variables. Using input variables More on variables with Oracle's SQL*Plus Table maintenance revisited (again) Continuation of table maintenance revisited (again) Using Input Variables Separate speaker notes for Using Input Variables More on variables with Oracle's SQL*Plus Separate speaker notes for More on variables with Oracle's SQL*Plus Table maintenance revisited (again) Separate speaker notes for Table maintenance revisted (again) Continuation of table maintenance revisited (again) Separate speaker notes for Continuation of table maintenance revisted (again) There was a qusestion about equijoin and looking at my notes, I could have done better. Try these! Equijoin notes Nonequijoin notes Now we are going to move on to views and reports and more on scripts. Introduction to views Introduction to reports Introduction to views Separate speaker notes for Introduction to views Introduction to Reports Separate speaker notes for Introduction to reports Resource on reports Scripts: To create a script use edit and the name of the script (.sql is added) and to run use @ scriptname. createdonor.sql Script to create donor Insert data into maintain table Insert data into maintain table ver 2 Assignments: Views and Reports Check back! |
| Week #4 Week of February 10th |
This is Enrollment Verification week and I have to verify you are in the class. If you have not passed in work or the email a week
verifying you are in the class, then you need to contact me now to make sure you are not withdrawn from the class. My husband
is recovering from open heart surgery so I will not be on campus. If you have questions, email me or contact my SI, Joe
Fletcher. We will start looking at subqueries. Subqueries More on subqueries You should also look at the presentation on these topics especially the one that accompanies More on subqueries. Subqueries Separate speaker notes for subqueries More on Subqueries Separate speaker notes for More on subqueries Zipped subqueries Assignments: Subquery Quiz Note that the reference in 6 and 7 should have been to the data in problem 5 rather than problem 4 Subquery assignment |
| Week #3 Week of February 3rd |
My husband is having emergency surgery this week so I am behind in getting back to you. We are going to start looking at the design of a database and the theory of relational databases. Please read information about third normal form and relational databases. I have put a variety of links to sources on the Web on the site under links and links to my site are listed below. For example: Normalization Please read the handout on definitions: Normalization definitions Please read the two examples - the first two postings under notes. Also view the slide presentation on normalization information about relational databases: Normalization - information on third normal form Separate speaker notes for normalization presentation Relational database information - information on 1 to 1, 1 to M, and M to M Separate speaker notes for relational database information Next we are going to start looking at relating tables: Introduction to multiple tables (relational) - joins Example of non-equijoin: nonequijoin Relational database examples Relational database notes and examples Goes with notes Introduction to multiple tables (relational) - joins - uses donor, donations and drive tables Separate speaker notes for relational database presentation Using join Join and where Information on join: www.sqlbook.com and then look up the kind of query you want: inner join for example. 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: 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. 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. |
| Week #2 Week of January 27th |
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.
See the help times above. These are the notes that you should 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 Separate speaker notes for More on maintaining an SQL table SQL functions - part 1 character Separate speaker notes for SQL functions - part 1 characters SQL functions - part 2 numeric & date Separate speaker notes for SQL functions - part 2 numeric & date More SQL functions (includes DECODE, ways to edit SQL code and nested functions) Separate speaker notes for more SQL functions Group functions Separate speaker notes for group 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. 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 January 20th |
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 download PuTTY download 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 and the port as 220 2) At the login screen enter your username and your Linux password. 3) When you see that you are at cisweb, enter sqlplus19c.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: Our first class is Jan 23rd (Thursday), so the first assignment is due Jan 30th (Thursday). 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! |
