This course is designed for developers, analysts, and others who need to use Oracle’s SQL language to query or modify data, and to create basic objects in Oracle databases. It is an introductory course, so no prior SQL knowledge is required.
Students receive a comprehensive introduction to Oracle’s implementation of the SQL language. Students use common query tools such as SQL Developer, TOAD, SQL*Plus, etc. to do course workshops to reinforce all concepts. Primary emphasis is placed on generating efficient queries to extract data from the database. Hands-on workshops constitute approximately 50% of the class.
This class is given as either public or private classes. For private classes the course can be customized to meet your specific training requirements.
Technical Requirements
Nothing is required for labs (workshops). SkillBuilders will provide everything you need for all hands-on labs. Modest PC or Mac specs are required to connect to the online class. Detailed specs can be found here.
Also, we strongly recommend using two monitors for this class.
“No suggestions for improvement. I will be recommending SkillBuilders to other departments. Geoff is a great instructor!”
