我有從2016-01-01(Jan)到2016-06-29(June)數據的名爲「radacct」的mysql數據庫表。由於某些原因,2016年6月20日至2016年6月25日的數據丟失。我有bin-log enabled
,所以我用「mysqlbinlog
」將bin文件導出到.sql文件,這些sql文件包含了從1月,2月,3月的舊數據......以及2016-06-20到2016-06丟失的數據-25。如何在不丟失當前數據的情況下恢復丟失的數據。使用mysqlbinlog從mysql數據庫表中的特定日期恢復數據
我正在考慮選擇包含缺失數據的文件(我使用日期字段來標識缺失的數據),並用REPLACE INTO
替換INSERT INTO
。
繼承人的SQL文件是什麼樣子

創建MySQL的二進制日誌文件測試,但它也將包括舊數據中已經存在。 –
從某種意義上講,較早的數據是在01年1月1日至16日和6月30日之間? –
是的,它也有數據在2016-01-01 00:00:00之前插入 –
