This one-day course provides an introduction to the MS Transact-SQL query language and detailed, hands-on experience writing SELECT queries. This course should be attended by those who are in a position to write or understand / modify existing SELECT queries. We will use MS SQL Server 2008, but the concepts apply to all relational databases. Attendees will learn about the structure of the Transact-SQL query language; the ways that queries may be issued to MS SQL Server; how to write and troubleshoot SELECT queries; how to work with date, time and string character data formats; how to group data and perform statistical summarizations; how to construct sub-queries to break down complex queries; and how to use standard table joins to retrieve data from multiple tables.
