Cecelia did a fine job in presenting the material and backing it up with examples. The assignments and questions on the quizzes were also appropriate. Enjoyed it!
I really wanted to thank Ms. Allison for conducting this course. I have tried to take an SQL course before but had to quit as the instructor taught so far above my head I could not understand the subject matter. This course was broken down into small bites and the quizzes and assignments helped to bring the concept home! I have enjoyed this course and would consider taking another course like this. I have already recommended this course to a friend who has also taken it. We both are very happy with the results. Thanks Again.
It made me feel good to know that Cecelia Allison is an expert on this subject. I bought both of her books and I have learned a lot. Her style of teaching makes learning easy and fun. I feel very fortunate to have learned from such an expert in the field.
It was a great class! It not only gave me the knowledge of SQL, but it also improved my abilities in other applications such as MS Access and MS Excel. The instructor presented the subject matter in a perfect balance of technical and practical. It was evident to me she has educational and in-the-field expert experience. She is also personable and helpful.
The course gave me a 'challenging' introduction to SQL. It introduced two types of databases that I had not previously used:Microsoft Access and SQL Query 7. The examples and assignments reinforced what had been taught in previous lessons. Thank you. I not only learned a great deal but had a good time.
Very nice introduction to SQL. This helped me gain a better basic understanding of things I'd been tampering with for several years. I could probably have saved myself many frustrating hours having taken a course like this a couple years back.
I really enjoyed Cecelia's writing style, and would like to comment on her excellent use of English and attention to detail/proofreading. Too many programmers, including instructors, don't seem to care how their messages are written as long as someone, somewhere can decipher the meaning. When an instructor cares enough to write well, I respect his/her knowledge and authority on the subject. I feel that this is very important when learning, as it is the instructor's job to make material more efficient to absorb. Thanks, Cecelia!
I was impressed with this class. After reading one of the discussion responses that I was actually doing intermediate to advanced work with SQL and understanding it, is a huge compliment to the instructor. I have never been on Access or done any work with any other databases before either. I have since gone onto my home computer and done a lot of work setting up databases with the help of this course. Thank you and I will definitely be taking more and taking the instructor’s advice on what to take in the future. Thank you again for a great class. After being unemployed for a year it is great to have something to make me feel good!
When I started this course I really didn't know anything about SQL. This course has helped me a lot in learning the basics about SQL. I feel more comfortable using it at work now. Cecelia's book was also a great help and I recommend it to those who are just starting to learn this course. I'm so glad I found this course, and I look forward for the next intermediate class that Cecelia is going to offer.
Course Code: sql
Explore the basic structure and history of relational databases and discover what SQL is and how it's used with a relational database. Then, you'll learn how to use SQL to filter and retrieve data from tables.
Learn how to use SQL to filter retrieved data using the ORDER BY clause and additional query terms that will help you customize your queries. Then, learn how to reformat retrieved data with calculated fields and functions.
Discover how to gather significant statistics from data using aggregate functions and learn how to use the GROUP BY clause in conjunction with an aggregate function to gather important statistics from a table as well as the HAVING clause in conjunction with an aggregate function to filter groups of data from a table. Then, learn how to extract data from multiple tables simultaneously, how to use calculated fields in subqueries, how to use the DATEPART () function in subqueries, and how to use aggregate functions in subqueries.
Learn how to use joins to gather information from two or more tables simultaneously. Then, discover how to manipulate data using the INSERT, UPDATE, and DELETE statements.
Find out how you can use SQL to create and maintain tables. You'll learn how to use the CREATE TABLE keywords to create a table, then we'll discuss how to use the ALTER TABLE, DROP TABLE, ADD COLUMN, and DROP COLUMN keywords to manipulate the tables themselves. You'll also learn how and why views are used in SQL.
Learn how transaction processing, constraints, and indexes are implemented in SQL. Finally, you'll find out how stored procedures, triggers, and cursors are implemented in SQL.
