Chapter 23: Hints

by Jonathan Gennick

  • Chapter
SQL Server T-SQL Recipes

Abstract

SQL Server’s query optimization process is responsible for producing a query execution plan when a SELECT query is executed. Typically, SQL Server will choose an efficient plan over an inefficient one. When this doesn’t happen, you will want to examine the query execution plan, table statistics, supporting indexes, and other factors that are discussed in more detail in Chapters 22 and 24. Ultimately, after researching the query’s performance, you may decide to override the decision-making process of the SQL Server query optimizer by using hints.
