Understanding the basic concepts of relational databases ensure refined code by developers. This course helps the participants to write subqueries, combine multiple queries into a single query using SET operators and report aggregated data using group functions. Controlling privileges at the object and system level are also dealt with in detail. This course covers creating indexes and constraints, and altering existing schema objects. Additionally, participants learn how to create and query external tables. In order to query and manipulate data within the database, to use the dictionary views to retrieve metadata and create reports about their schema objects, participants get to understand the advanced features of SQL. Some of the date-time functions available in the Oracle Database are also covered. This course also discusses how to use the regular expression support in SQL.
For this course, the main development tool used is Oracle SQL Developer. SQL*Plus is available as an optional development tool
After completing this course, students will be able to:
- Display data from multiple tables using the ANSI SQL 99 JOIN syntax.
- Identify the major structural components of the Oracle Database 11g.
- Create reports of aggregated data.
- Write SELECT statements that include queries.
- Retrieve row and column data from tables.
- Run data manipulation statements (DML) in Oracle Database 11g.
- Create tables to store data.
- Utilize views to display data.
- Control database access to specific objects.
- Manage schema objects.
- Manage objects with data dictionary views.
- Write multiple-column sub-queries.
- Employ SQL functions to retrieve customized data.
- Use scalar and correlated sub-queries.
