Have you ever wondered why a T-SQL query that usually runs quickly suddenly slows down to a miserable crawl? Maybe there has been a change to the query, but maybe not. Unlike procedural code – where you tell the computer what to do – querying a database is different. You tell the database engine what you want, and the optimizer must figure out how to do it. Luckily, SQL Server provides a tool called the graphical execution plan to help you see what is going on under the covers. Does your query scan a billion row table to find one row? Does it take advantage of an index but then make thousands of trips to the actual table to grab one column? Attend this session to learn how to use graphical execution plans to understand how to make your queries more efficient.
