Objectives of the training
To provide the knowledge and skills required to formulate queries and to update a database using the SQL language.Targeted audience
Developers (other than supervisors), Web specialists and those working in networking positions (other than security).Prerequisite
Knowledge of conceptual data modeling (Course BD101) would be an asset.Trainers
Course architecture
It is important to master SQL (Structured Query Language), as it is one of the most popular languages for querying relational databases. With this course, participants will be able to communicate with databases to manipulate the data they contain.
Introduction to Databases
In this module the participant will learn about the essential components of modern computer systems and the characteristics of persistent data.
- What is data and what are the types of data
- What is a database and what is a database management system (DBMS)
- Database schema and data definition language
- Data manipulation and query language: SELECT, INSERT, UPDATE, DELETE
- Client-server architecture
- Why is semantic integrity a priority?
- Definition and ownership of transaction management (COMMIT)

The SQL DDL language
In this module the participant will see the characteristics of SQL programming
- 4 subdivisions of the language: DDL/DML/DCL/TCL
- Create a table (CREATE TABLE)
- General syntax for creating a table
- SQL types (exact or approximate numeric)
- Strings of characters
- Date and time, etc.
- Deleting a table (DROP TABLE) with RESTRICT and CASCADE
- Modifying the schema of a table (ALTER TABLE)
- How to manage integrity constraints (static or dynamic)
- Virtual tables: implementation, update according to the ANSI standard and by query modification

- SQL IN to validate the value of a column (Syntax, conditions...)
- SQL LIKE for searches on specific formats
- The TOP clause to limit the number of rows returned
- The operators
- Mathematical functions
