Introduction to Transact-SQL

Alert Me

Description

In this course, you’ll master the skills needed to write Transact-SQL SELECT statements accessing one or more tables. You’ll also learn the various techniques for combining data, filtering the results and how to control and format the statement output.

You’ll gain a foundation understanding of a SQL Server database and use the tools available to discover the database definition, submit queries and view results.

We teach students how to write a query the same way that SQL Server processes a SQL statement – following a step-by-step process for creating SQL queries from business requirements. This approach uses the natural way of breaking down a problem into logical steps. Each step can be validated before moving to the next step. This differs from most courses, which present SQL as a set of features.

Class lectures highlight and explain Transact-SQL concepts which are reinforced with extensive follow-along demonstrations and hands-on labs.

What You Will Learn
  • Use the SQL Server Management Studio tool to browse the definition of the database, find necessary object names, create database diagrams, and execute a SQL query to return data rows.
  • Write a simple SELECT statement, returning all the columns and rows and formulate meaningful join strategy to bring together all necessary data.
  • Write a WHERE clause to filter the rows based on equality, a list of values, a range of values and a wildcard character condition.
  • Understand the impact on filtering based on implicit data conversions using data type precedence and how to create a proper search argument.
  • Control the display of data in a SQL SELECT including renaming columns, using simple expressions with function to change output values, conditionally change the output values using CASE expressions, sort the result set, eliminate duplicate rows and control the number of rows returned.
  • Write Transact-SQL queries that aggregate values across rows based a group and filter the result set based on aggregated values.
