Oracle Database 11g SQL

3 days
AO3 - Version:2
Description
This course provides the essential SQL skills that allow developers to write queries against single and multiple tables, manipulate data in tables, and create database objects. Students learn to execute queries, inserts, updates, and deletes against a database and create database tables, constraints, sequences, indexes, views, and users. Students learn to control privileges at the object and system level. Students learn to use the advanced features of SQL in order to query and manipulate data within the database and use the dictionary views to retrieve metadata. Students also learn about Oracle database’s built-in functions including date-time functions and the regular expression support in SQL.
Intended audience
The course is targeted for those interested in mastering the SQL language in Oracle environment
