我重組了您的查詢，希望能夠提供顯着的性能改進時間。通過使用STRAIGHT_JOIN告訴MySQL按照你所說的順序（或者我在這裏調整過）來完成。最內層的第一個查詢「PreQuery」別名按照您的導入包和通用導入條件啓動，導入到帳戶的帳戶中...通過在那裏預先應用WHERE子句（以及您將要測試的內容，添加您的限制條款在這裏）你正在預先加入這些表格，並且在浪費任何時間試圖獲得客戶，地址等信息之前，將它們排除在外。在查詢中，我調整了連接/左連接以更好地顯示底層鏈接表的關係（主要針對其他人閱讀）。
正如另一個人指出的，我在PREQUERY中所做的工作可能是用於瀏覽和提供頁面的主查詢列表中的「Account.ID」記錄的基礎。我會很好奇你的現有表現，特別是在10,000限制範圍內。
PREQUERY獲得獨特的元素（包括下游，銀行，月份，年份和類別使用的帳戶ID），因此這些表不必在加入過程的其餘部分重新加入。

老兄，你真的想要從SQL查詢中的字段中刪除銀行的名稱。 – smci 2011-11-23 00:00:29
你有三個很好的答案值得選擇。你從來沒有回答Karelzarath的關鍵問題**'必須查詢真的返回215個字段中的每一個字段，並使用29個連接嗎？'**爲什麼不拿出一個簡單的30個字段的查詢，然後至少你可以測量每增加一個連接，性能都會下降。此外，您在STRAIGHT_JOIN DRapp上的表現數字是什麼給了你的？ – smci 2011-11-23 00:10:04
