Oracle Database SQL Introduction is the course in which students will learn how to write basic SQL statements to view data, insert data, update existing data and delete data in database. Following are topics which students will learn about this course:
The more which students will learn would be that Structured Query Language (SQL) is the set of statements with which all programs and users access data in an Oracle database. Application programs and Oracle tools often allow users access to the database without using SQL directly, but these applications in turn must use SQL when executing the user's request. This chapter provides background information on SQL as used by most database systems.
This course will help to write sub queries, combine multiple queries into single query SET operators and report aggregated data using group functions. It will help to understand the advanced features. Learning these features will help query and manipulate data within database, use the dictionary views to retrieve metadata and create reports about their scheme objects. Some of the date-time functions available in the Oracle Database will also be covered. It will discuss to use the regular expression support in SQL through expert instructions.
