开启binlog

在my.ini中添加以下两行代码：

log-bin=mysql-binserver-id=1

注意要写在[mysqld]范围内才会生效

查看binlog存放日志文件目录

show variables like '%datadir%';

查看binlog文件名

show master logs;

将binlog转换成sql

mysqlbinlog --no-defaults --base64-output=decode-rows --base64-output=decode-rows -v --database=test --start-datetime="2023-07-26 16:30:00" --stop-datetime="2023-07-26 17:00:00" D:\phpstudy_pro\Extensions\MySQL5.7.26\data\mysql-bin.000001 > D:\phpstudy_pro\Extensions\MySQL5.7.26\data\hsb.sql

创建test.vbs将binlog的delete转换成insert

function replaceregex(patern,str,tagstr)dim regex,matchesset regex=new regExpregex.pattern=paternregex.IgnoreCase=trueregex.global=truematches=regex.replace(str,tagstr)replaceregex=matchesend function'Mysql binlog DELETE转INSERT=========='VBS打开文本文件Set oldStream = CreateObject("ADODB.Stream")oldStream.CharSet = "utf-8"oldStream.OpenoldStream.LoadFromFile("hsb.sql") 'binLog生成的DELETE原日志文件oldText = oldStream.ReadText()newText=replace(oldText,"### DELETE FROM", ";INSERT INTO")newText=replace(newText,"### WHERE", "SELECT")newText=replace(newText,"###", "")newText=replace(newText,"@1=", "")newText=replaceregex("@[1-9]=",newText, ",")newText=replaceregex("@[1-9][0-9]=",newText, ",")oldStream.Close'VBS保存文件Set newStream = CreateObject("ADODB.Stream")newStream.Type = 2 'Specify stream type - we want To save text/string data.newStream.Charset = "utf-8" 'Specify charset For the source text data.newStream.Open 'Open the stream And write binary data To the objectnewStream.WriteText newTextnewStream.SaveToFile "hsb_insert.sql", 2 'DELETE转成INSERT以后的新的SQL文件名newStream.Close

双击执行test.vbs生成hsb_insert.sql

找到insert语句并执行
