Transact SQL Programming (TSQL)

Duration: 3 Days

Objectives

This course is aimed at SQL Server database developers, administrators and analysts who need a little bit more than SQL can do alone. SQL Server provides a powerful scripting language called Transact SQL, which enables developers to extend the capabilities of the SQL language. Using Transact SQL (TSQL) powerful scripts, stored procedures, functions and triggers can be produced to enable extracted information to be processed further, or to enable complex transformations of data prior to, during or after an insert, update or delete, or to implement automated updates and audit trails. Covers SQL Server 2005 through to SQL Server 2016.

Pre-requisites

Delegates should have SQL Server SQL language experience to the level of our Advanced Querying of SQL Server Databases course.

Course includes

A comprehensive set of reference notes covering course topics and follow-up telephone support.
