數據存儲優化

Question

我有一個表格，其中可以通過單擊添加/刪除按鈕來動態添加/刪除新行。

當我嘗試將新添加/刪除的行保存回數據庫時，我的問題就開始了。我設法使用jQuery的Ajax來保存數據，所以我沒有使用post var，而是「收集」每個輸入的所有數據。我設法將所有這些數據，並將它們發送到我的store.php存儲它們。

我的問題是，我怎麼能救我的還真沒有幾個查詢的變化，我的意思是，這是什麼store.php被髮送到我的MySQL服務器的輸出：

UPDATE transport SET transporttype = "3" WHERE id = 1 
UPDATE transport SET transporttype = "2" WHERE id = 6 
UPDATE transport SET transporttype = "1" WHERE id = 7

UPDATE transport SET transportindemnisationmontant = "600" WHERE id = 1 
UPDATE transport SET transportindemnisationmontant = "600 €" WHERE id = 6 
UPDATE transport SET transportindemnisationmontant = "600" WHERE id = 7 
UPDATE transport SET transportindemnisationmoyen = "1" WHERE id = 1 
UPDATE transport SET transportindemnisationmoyen = "1" WHERE id = 6 
UPDATE transport SET transportindemnisationmoyen = "1" WHERE id = 7 
UPDATE transport SET transportreclamationobservation = "Non pas d'observation" WHERE id = 1 
UPDATE transport SET transportreclamationobservation = "non plus" WHERE id = 6 
UPDATE transport SET transportreclamationobservation = "encore moins" WHERE id = 7 

沒有必要告訴你這個速度太慢了，像5秒鐘一樣存儲所有數據。

Answer 1

你可以利用ON DUPLICATE KEY UPDATE：

INSERT INTO table (id,Col1,Col2) VALUES (1,1,1),(2,2,3),(3,9,3),(4,10,12) 
ON DUPLICATE KEY UPDATE Col1=VALUES(Col1),Col2=VALUES(Col2); 

是做什麼的小總結：

如果你指定ON DUPLICATE KEY UPDATE，行插入該 會導致重複值在一個唯一索引或PRIMARY KEY中，一個 執行舊行的UPDATE。

如果您正在從PHP腳本運行這些查詢，則應確保您使用的是預準備語句（mysqli或PDO）。如果你使用的是普通的mysql擴展，那麼你將使用每個查詢往返數據庫服務器。但是，通過準備好的語句，可以將類似的查詢分組到一個準備好的語句中，並使用不同的數據多次執行它。
