Synopsis

Transact-SQL (or T-SQL) is Microsoft’s proprietary extension to SQL. This Transact-SQL programming training course will introduce you to the programming features of the language, using Microsoft SQL Server. With prior knowledge of SQL assumed, this course looks at the procedural programming language capabilities of T-SQL, such as local variables, flow control constructs, error handling and built-in functions. You will learn how to write your own functions to be used in SQL Server just in the way you use built in functions such as UPPER and GETDATE. You will also learn to write procedures, allowing you to execute any number of commands in a single database call. You'll write triggers, which automatically fire in response to a predefined database event - for example allowing you to automatically archive changed or deleted records. You'll find out how to get information from the database, such as whether there is an existing open transaction. All in all your capacity to work with SQL Server will massively increase over just using plain old SQL

FAQs

  • What are the course times?
    • Most course days run from 9.30am to around 4pm, however as we are currently only offering one on one remote courses during the current crisis, we can be quite flexible if you would like to do different hours.

  • Do I need anything?
    • For our live remote one on one courses you only need a computer with the Chrome browser, and speakers or headphones to hear the instructor. When it comes time to do an exercises you can either connect to our computer to do them, or do them on your own computer. We will advise for your specific course what software you would need to do them on your own computer but don't worry, you can connect to ours if you prefer.
