Indexing Myths and Best Practices,In the past few chapters, indexes have been introduced along with how they are structured. In the upcoming chapters, strategies will be discussed to build indexes and ensure that they behave as expected. In this chapter, some common myths will be dispelled while a foundation is built for creating effective indexes.小平面 发表于 2025-3-28 19:02:20
Index Maintenance,Like anything in life, indexes require maintenance. Over time, the performance benefits of indexes can wane or, through data modifications, their sizes and the underlying statistics can drift and bloat. To prevent these issues, indexes must be maintained. Doing so will help ensure that a database will remain a lean, mean query-running machine!爱好 发表于 2025-3-29 01:22:56
Index Fundamentals,be introduced. This will lead to a discussion of how data is stored in indexes, focusing on clustered, non-clustered, and columnstore indexes. We will also explore heaps. Indexing is a key component in any database, whether it is stored on premises or in Azure (or another cloud service).钉牢 发表于 2025-3-29 05:19:30
Index Metadata and Statistics,atistics provide insight into how SQL Server manages and uses indexes. It also provides the information needed to determine why an index may or may not be selected and how it is behaving. This chapter will provide a deeper understanding about where and how this information is collected. Some additio落叶剂 发表于 2025-3-29 11:13:37

Full-Text Indexing,has been the . length used with variable-length character data types . and .. This means you can store up to 2 GB worth of character information within a single column. While SQL Server can store this information, the 1,700-byte limit for non-clustered indexes and 900-byte limit on clustered indexes拥挤前 发表于 2025-3-30 02:48:12
