Developing SQL Queries for SQL Server®: Hands-On

 
Course: 534   Duration: 4 Days
 
 

You Will Learn How To

  • Develop complex and robust SQL queries for SQL Server 2008, 2005 and 2000
  • Query multiple tables with inner joins, outer joins and self joins
  • Transform data with built-in functions
  • Summarise data using aggregation and grouping
  • Execute analytic functions to calculate ranks
  • Build simple and correlated subqueries

Course Benefits

Microsoft's Transact-SQL is the cornerstone of all SQL Server database operations. In this hands-on course, you learn to exploit the full potential of the SELECT statement to write robust queries using the best query method for your application, test your queries, and avoid common errors and pitfalls.

Who Should Attend

Those who are developing systems using SQL Server databases, or who are using SQL to extract and analyse data from SQL Server databases. Knowledge of SQL Server at the level of Course 137, "SQL Server 2008 Comprehensive Introduction", or Course 925, "SQL Programming Language Introduction", is assumed.

Hands-On Training

Learn by doing as you use Transact-SQL to solve problems and maximise performance. Instructor-led exercises include:
  • Handling NULL values in expressions and conditions
  • Coding inner and outer joins
  • Implementing self joins
  • Computing aggregate results
  • Adding subtotals and grand totals to aggregate results
  • Employing ranking and analytic functions
  • Reusing subqueries as common table expressions
  • Analysing query plans and tuning queries
