Queries with Oracle SQL

In the course Queries with Oracle SQL from SpiralTrain participants learn the syntax and use of the query language SQL in the context of an Oracle database.

SQL Intro

After an introduction to relational databases and Oracle, the Oracle installation, environment and tooling, the basic aspects and backgrounds of SQL are discussed. Oracle, like other DBMS systems, has added extra features of its own to standard SQL and these are also discussed in the course.

Data Definition and Data Manipulation

In the first place the course covers how SQL statements can be created and executed in Oracle. Subsequently the various components of SQL are treated step by step, such as Data Definition Language with CREATE TABLE and Data Manipulation Language with INSERT and UPDATE.

SQL Select Queries

Next attention is paid to writing SELECT queries. The grouping of data by means of GROUP and HAVING clauses is also on the program of the course.

SQL Functions

The various functions in SQL are discussed. Among other things, the mathematical, conversion and aggregation functions for calculating sum and average are treated. Attention is also paid to features specific to Oracle.

Joins

Next the course covers how to combine data from different tables by means of joins. The various types of joins like inner and outer joins are discussed.

SET Operators

Finally attention is paid to the application of SET operators such as UNION and INTERSECT. The command line interface of SQL*Plus is also treated.
