Quick Info: Latest update: 10/23/2017More than 220 LecturesVery Comprehensive with extra lectures on Database AdministrationMay help in obtaining Oracle Database 12c SQL Certification. With FULL Subtitles for all the video lessons About This Course: Welcome to the course, The Complete Oracle SQL Course. This course introduces SQL, which is an acronym for 'Structured Query Language', to its students. This is based on Oracle's SQL implementation for Oracle Databases. The lessons are based on Oracle 12c Database and SQL Developer Tools running in Windows 10. This course may help you in taking a step towards.. in becoming an 'Oracle SQL Developer'in achieving 'Oracle SQL Certification' About the Name of this Course: When I started out to create this course, I wanted to create a Beginner Level Oracle SQL course. So I named it as 'SQL Development for Beginners'. However as I progressed, I decided to make it much more comprehensive and cover most of the topics in the curriculum of Oracle SQL exam 1Z0-071. And so I renamed it to, The Complete Oracle SQL Course. So, this course starts with Beginner Level lessons and progresses into next levels. About SQL: SQL is used to interact with Database Systems. As per ANSI (American National Standards Institute), SQL is the standard language for Relational Database Management Systems. SQL has been the prominent language to interact with various Database Systems for many decades. While many languages that existed two decades ago are extinct now, SQL has always maintained its supremacy in the RDBMS world. Over the time, it has only advanced with new features and standards. And it seems to stay that way for years to come. About Oracle Database: Oracle Database is one of the prominent Database Systems in the RDBMS (Relational Database Management Systems) segment. Some of the other prominent Database Systems are Microsoft SQL ServerMySQLSybase ASE. They also use SQL to interact with their Database Systems. While there are subtle differences between each of their SQL implementations, a SQL as a whole, is generally very standard. So a person with SQL knowledge in one platform such as Oracle, may find it easier to learn and code for other Database Systems such as Microsoft SQL or MySQL.  The point is, once you learn SQL, then your reach into the job market is very wide. About the Curriculum: The curriculum has been carefully designed to introduce the Oracle RDBMS environment first. Then it moves on to various types of SQL Statements such as DDL, DML and TCL. And next, it goes to the depths of various SQL Statements, Conditions, Sorting, Functions, Grouping etc.. It also gives Database Administration tips, as needed. It is also covers most of the topics from the Oracle SQL Certification Exam 1Z0-071 Oracle Certification: Oracle awards certain certifications that are recognized globallyOne such certification is Oracle Database 12c SQL Certified AssociateThe exam for that certification is (currently as of May 2016), 1Z0-071. The topics in this course covers most of the topics for that exam. Oracle Certification - Declarations  While this course covers most of the topics for that exam, this course is not a sole material for that exam. Additional materials such as Oracle's recommended Books may be needed. This course is NOT an official course from Oracle Corporation. This course has been developed individually by its author. About the Instructor: The instructor of this course, Mr. Sam Dhanasekaran, has more than 20 years of IT experience. It predominantly includes Database Support, IT Support and Recruiting. About Previews: More lessons have been opened for public previews than the required amount. Please take your time to go through all of them. This will give you an idea about the instructor's presentation style, technical knowledge etc. Subtitles/Closed Captions: All the video based lectures contain subtitles or closed-captions.

11. The Ultimate Oracle SQL Course: SQL Made Practical

(4,410)

* Covers Oracle Database 11g, Oracle 12c, Oracle 18c, and Oracle 19cOracle is currently the most popular relational database management system in the world. It is used by thousands of big companies who are usually willing to pay good salaries to the right people, which includes those with practical Oracle SQL knowledge that is based on best practices and experience.                     Most SQL courses give you theoretical SQL knowledge. In this course, you will learn by actually writing code. Learn Oracle SQL in a practical and smart way and jump-start your career as an Oracle SQL developer: Get comfortable writing code using Oracle SQL Developer. Learn how to read, filter, and sort information from database tables. Learn how to use all types of operators in Oracle SQL. Learn how to use numeric, text, date, conversion, aggregate, analytic, and other types of Oracle SQL functions. Learn how to add, modify, and delete information from Oracle databases using SQL. Learn how to use SQL to create and use tables, constraints, sequences, indexes, and views. Learn all SQL basics plus intermediate and advanced features and techniques. Get tips and knowledge that is usually only learned through years of SQL experience. Much more. Carlos created this course because most courses, if not all, focus too much on "telling" or "demonstrating" how to do things, but don't give you, as a student, the opportunity to test and practice what is being taught. Some of them tell you to practice or to do things along with the instructor, but unfortunately, such an approach doesn't really work. Seeing how things are done or just copying or repeating what you see on the screen is not going to help you learn SQL. You might feel that you are learning, but when the time comes for you to write a command on your own, you are most likely not going to feel very confident. Here you will learn and practice much more than just SQL basics. Content and Overview: This course was designed with beginners in mind, but if you have some previous SQL knowledge, you will still learn a lot.  After setting the learning environment, it starts with the most basic concepts about databases in general and a very short introduction to Oracle and the SQL language. You will start learning about the simplest SQL statements, and before you even notice it, you will have covered all the SQL basics and will be gradually progressing to more advanced concepts. The course includes several topics that some people, including experienced developers and other instructors, consider advanced, such as Analytic Functions, Hierarchical Queries, Pivot and Unpivot features, and many more. It does not include demonstration lectures because the whole course is a coding demonstration. In 90% of the video lectures, you will be watching the instructor's computer screen while he types, explains, and runs Oracle SQL code. It does not include labs at the end of each section because practically every lesson has a coding task for you to practice what you are learning. Please note that PL/SQL (Oracle's procedural language) is not covered in this course. The instructor will not only teach you SQL. He will share his decades of Oracle experience with you through what he calls "experience tips". Those tips can really help you differentiate and stand out. Final words from the instructor: You could enjoy being seen as an experienced and knowledgeable SQL developer by your friends, peers, and potential employers in a very short time, but you have to take action. If you want my help, you've got it.-Carlos, founder of the Standout-Dev Academy...

Go ahead and click the enroll button, and I'll see you in lesson 1! CheersStart-Tech AcademyFAQ'sWhy learn SQL?SQL is the most universal and commonly used database language. It powers the most commonly used database engines like PostgreSQL, SQL Server, SQLite, and Oracle SQL. Simply put, If you want to access databases then yes, you need to know SQL. It is not really difficult to learn SQL. SQL is not a programming language, it's a query language. The primary objective where SQL was created was to give the possibility to common people to get interesting data from the database. It is also an English-like language so anyone who can use English at a basic level can write SQL queries easily. SQL is one of the most sought-after skills by hiring employers. You can earn good moneyHow much time does it take to learn SQL?SQL is easy but no one can determine the learning time it takes. It totally depends on you. The method we adopted to help you learn SQL quickly starts from the basics and takes you to advanced level within hours. You can follow the same, but remember you can learn nothing without practicing it. Practice is the only way to learn SQL quickly. What's the difference between SQL and PostgreSQL?SQL is a language. Specifically, the Structured Query LanguagePostgreSQL is one of several database systems, or RDMS (Relational Database Management System). PostgresSQL is one of several RDMS's, others of which are Oracle, Informix, MySQL, and MSQL. All of these RDMSs use SQL as their language. Each of them has minor variations in the dialect of SQL that they use, but it's all still SQL. Which is better, PostgreSQL or Oracle SQL?Both are excellent products with unique strengths, and the choice is often a matter of personal preference. PostgreSQL offers overall features for traditional database applications, it is open source and offers great support. Oracle Database has decades of experience and high levels of development expertise. It not only provides more transactions per second than PostgreSQL, but also arguably provides higher levels of security. However, many of Oracle's security features come at an added cost. Oracle is secure and ensures that user data is not tampered with through prompt updates. Both dialects are very popular today, but PostgreSQL has gained market share recently and is trending upwards because (some have claimed) it has features more suited to today's dynamic development requirements.. Who uses these databases?Here are a few examples of companies that use PostgreSQL: Apple, BioPharm, Etsy, IMDB, Macworld, Debian, Fujitsu, Red Hat, Sun Microsystem, Cisco, Skype. Companies that use Oracle SQL: Gartner, Nike, Costco, Airbnb, eBay etc...
