如果運行庫優化程序已禁用，則為 -
The query optimizer treats the view like a table with clustered index
查詢優化器將視圖當成包含聚集索引的表處理。 -
Access plan directives that force the optimizer to use the designated access method for data retrieval, either sequential scan or index scan
訪問計劃指示，強制優化器使用指定的訪問方法進行數據檢索，要麼是連續掃描，要麼是索引掃描。 -
Since summary data is precomputed in the mqts, db2 optimizer may rewrite a specific query to access an mqt instead of based tables because the optimizer can recognize if result sets can be derived from an mqt with less predicted cost
因為匯總數據在mqt中預先計算，所以db2優化器可以改寫特定查詢來訪問mqt ，而不是基礎表，因為優化器可以識別是否能以較少的預計成本從mqt得到結果集。 -
Because the sql server 2005 query optimizer typically selects the best execution plan for a query, we recommend that hints, including
由於sql server 2005查詢優化器通常為查詢選擇最優執行計劃，因此建議只將提示包括 -
Disabling automatic statistics recomputation can cause the query optimizer to choose a less optimal strategy for queries that involve the specified table
禁用自動統計信息重新計算會導致查詢優化器為涉及指定表的查詢選擇非最佳的策略。 -
Because the sql server 2005 query optimizer typically selects the best execution plan for a query, we recommend that hints, including query hint, be used only as a last resort by experienced developers and database administrators
由於sql server 2005查詢優化器通常為查詢選擇最優執行計劃，因此建議只將提示（包括< query _ hint > ）用作經驗豐富的開發人員和數據庫管理員的最終手段。 -
Because the sql server 2005 query optimizer typically selects the best execution plan for a query, we recommend that hints, including table hint, be used only as a last resort by experienced developers and database administrators
由於sql server 2005查詢優化器通常為查詢選擇最優執行計劃，因此我們建議，只有在萬般無奈的情況下才由經驗豐富的開發人員和數據庫管理員使用提示（包括< table _ hint > ） 。 -
Another way to influence the optimizer is to use query directives
影響優化器的另一種方式就是使用查詢命令。 -
Query directives are hints in sql queries that instruct the optimizer how to execute the query
