SQL Training

Course Overview:

This SQL training course is designed for students new to writing SQL queries. A typical student will need to learn SQL to build applications or to generate business reports. For the most part, the SQL learned in the course is applicable to all major databases. In the few cases in which there are differences between the databases, these differences will be pointed out. They also can Understand how relational databases work, Learn to use SQL to output reports, Learn to write queries getting data from multiple tables.
