它已經一段時間，因為我看著oscommerce的軟件包。 這是一個偉大的平台，為構建一個網上商店在線。
然而，當他們問，如果你是上面的“MYSQL \ V5”或低於它開始讓我緊張。 很顯然，我並不孤單InnoDB的存儲引擎的選擇應該是與關注。
所以，我決定挖多一點......
我假設您運行的是更多更新的MySQL，或者最起碼，你打算做很快。

如果您運行的是一家店，客戶數據，然後在你選擇的數據庫，穩定性應該是一個重要的因素。我想更新這些InnoDB的輕鬆。
>SELECT
CONCAT('ALTER TABLE ',TABLE_SCHEMA,'.',TABLE_NAME,' ENGINE=InnoDB;') as query
INTO OUTFILE '/tmp/update_oscommerce.sql'
FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA NOT IN ('mysql', 'INFORMATION_SCHEMA') AND ENGINE IS NOT NULL AND TABLE_SCHEMA = 'oscommerce'
GROUP BY TABLE_SCHEMA, TABLE_NAME;
此查詢創建一個簡單的ALTER TABLE所有osCommerce的表。 如果您已設置你的表前綴與其他表到數據庫中，你可以調整相應的查詢。
mysql -p < /tmp/update_oscommerce.sql
所以沒有工作？ 是，你必須要知道，你會看到一個不同的大小和索引大小。

管理網站，以及購物車測試快速測試顯示一切工作得很好，到目前為止。 一個簡單的辦法，這將取決於表的大小，速度有多快，它為你做。 這個例子是一個全新的安裝。
如果你已經複製，然後能夠關閉的奴隸和更新的表上的奴隸，首先將是一個良好的開端。 然後旋轉高手，除非你能承受的停機時間。
如果你沒有複製.. 那麼你應該看看它。 你也應該，我希望你做什麼，它備份至少每天。
