商品描述
Every action in SQL Server - queries, updates, whatever - leaves a set of tiny footprints; SQL Server records all that valuable data and makes it visible through Dynamic Management Views, or DMVs. A DBA or developer can use this incredibly detailed information to significantly improve the performance of queries and better understand what's really going on inside a SQL Server system
SQL Server DMVs in Action is a practical guide that shows how to obtain, interpret, and act on the information captured by DMVs to keep SQL Server in top shape. The 100+ samples provided in this book will help readers master DMVs and also give them a tested, working, and instantly reusable SQL code library.
商品描述(中文翻譯)
每個在 SQL Server 中的操作 - 查詢、更新等等 - 都會留下微小的足跡;SQL Server 記錄了所有這些寶貴的數據,並通過動態管理視圖(Dynamic Management Views,簡稱 DMVs)使其可見。資料庫管理員(DBA)或開發人員可以利用這些極其詳細的信息來顯著改善查詢性能,並更好地理解 SQL Server 系統內部實際發生的情況。
《SQL Server DMVs in Action》是一本實用指南,展示如何獲取、解釋和利用 DMVs 捕獲的信息,以保持 SQL Server 的最佳狀態。本書提供的 100 多個範例將幫助讀者掌握 DMVs,並為他們提供一個經過測試、可用且即時可重用的 SQL 代碼庫。
