开启binlog
在my.ini中添加以下两行代码：
log-bin=mysql-bin
server-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,matches
set regex=new regExp
regex.pattern=patern
regex.IgnoreCase=true
regex.global=true
matches=regex.replace(str,tagstr)
replaceregex=matches
end function
'Mysql binlog DELETE转INSERT==========
'VBS打开文本文件
Set oldStream = CreateObject("ADODB.Stream")
oldStream.CharSet = "utf-8"
oldStream.Open
oldStream.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 object
newStream.WriteText newText
newStream.SaveToFile "hsb_insert.sql", 2 'DELETE转成INSERT以后的新的SQL文件名
newStream.Close
