我有一个名为“radacct”的 mysql 数据库表，其中包含从 2016-01-01(一月)到 2016-06-29(六月)的数据。由于某种原因，从 2016-06-20 到 2016-06-25 的数据丢失了。我启用了 bin-log，所以我使用“mysqlbinlog”将 bin 文件导出到 .sql 文件，这些 sql 文件包含来自一月、二月、三月的旧数据。以及在 2016-06-20 到 2016-06-25 丢失的数据。如何在不丢失当前数据的情况下恢复丢失的数据。
我正在考虑选择包含缺失数据的 .sql 文件(我使用日期字段来识别缺失数据)并将 INSERT INTO 替换为 替换成。
这是sql文件的样子

最佳答案
你可以使用mysqlbinlog --start-datetime="2016-01-01 00:00:00" --stop-datetime="2016-06-29 23:59:59" <log file> > <sql file path>
