It was always said that bulk INSERT and update efficiency is higher than non-bulk, but has not used the bulk processing of data, and now because the project needs to deal with a large amount of data, so the use of bulk processing features, Java code is as follows:1.java implements BULK INSERT data:Connection Conn; Try{class.forname ("Com.mysql.jdbc.Driver"); Conn
