Sample Chapter from Murach's SQL Server 2008 for Developers

  • Article

Chapter 3 from Murach’s SQL Server 2008 for Developers shows you how to retrieve data from a database table. In the process, you’ll master the basic skills that you’ll use in coding almost any SELECT statement, no matter how complex. At that point, you’ll be ready to learn how to code joins, summary queries, subqueries, and action queries, and then move on to working with server-side features like cursors and stored procedures.

Question of the Day

Query Plan Regressions --

For the Question of the day, I am going to go deep, but try to be more clear, as I feel like I didn't give enough info last time, leading folks to guess the wrong answer... :) For today's question:  You’re troubleshooting a performance issue on a critical stored procedure. You notice that a previously efficient query now performs a full table scan instead of an index seek. Upon investigating, you find that an NVARCHAR parameter is being compared to a VARCHAR column in the WHERE clause. What is the most likely cause of the query plan regression?
