Learn Oracle SQL prepare for Certified Associate 1Z0-071 Course


This course is the foundation of the Oracle Database SQL 1Z0-071 certification. It details the SELECT statement and the additional requirements for controlling user access. It is divided into 6 sessions, and each session requires one morning or afternoon to complete.

Jimmy said: “The course is designed in a way that people who don’t know Oracle can understand it. It’s a good study. Thank you very much for making such a good course.”

Henry said: “I want to thank the teacher for this amazing course. This course and other materials helped me pass the 1Z0-071 exam last Saturday.”

Section 1

We will install Oracle Express Edition and Oracle SQL Developer for free. Then we take a look at the 6 main clauses of the SELECT statement: SELECT, FROM, WHERE, GROUP BY, HAVING and ORDER BY.

Then we will start to create tables, but found that if we don’t understand the data types, we can’t go very far. Then we will study string, date, and number types and functions, as well as functions to convert between them.

Section 2

We will revisit the SELECT statement and introduce it in more detail. We will create tables and join them together. After completing this course, you should have a safe understanding of the 6 main clauses of the SELECT statement (the most important part of Oracle SQL).

Section 3

In Session 3, we will find the missing data and learn how to delete and update the data. We will study the difference between implicit and explicit transactions, as well as various constraints, including primary keys and foreign keys.

Section 4

We will start by saving our query in the view. Then we will combine the tables, instead of adding extra columns by using JOINS, but adding extra rows, such as Oracle SQL set operators such as UNION, INTERSECT, and MERGE. Then we will look at analysis functions that use the OVER clause.

Section 5

Add the total to our SELECT query at the beginning of Session 5. Then we will study subqueries and how to add them to the FROM, SELECT, and WHERE clauses, as well as to the WITH clause. Finally, we will look at Oracle SQL self-joins, which are useful when you have a hierarchy.

Section 6

Session 6 starts with two additional data types, TIME ZONE and INTERVAL data types and functions. Then we will look at SEQUENCE and INDEX and how they are displayed in the data dictionary. Then we will create new users and assign permissions and roles to them, and we will complete the last few requirements of the exam.

No prior knowledge is required-we will even install Oracle Database and Oracle SQL Developer on your computer for free!


Upon completion, you will learn how to manipulate numbers, strings, and dates, and how to create databases and tables, create tables, insert data, and create analyses, and learn how to use them in Oracle SQL.


  • You need to know how to use a computer and want to know how to use spreadsheets.
  • No prior knowledge of Oracle SQL database or any other database is required-although the more knowledge you have, the better.
  • The Oracle SQL database cannot be easily installed on Mac OS. If you want to install it on a Mac, you need to dual boot into Windows or run Parallel Desktop.
  • You don’t even need to install Oracle SQL Database-I will tell you you must install it on your computer for free!
