achieve 1000W of data, it will take some time. The following methods can be used to further improve the speed:First create a table with the same table structure:CREATE TABLE fortest_2 like fortest;Then insert 5W data according to the Fortest tableINSERT intofortest_2 (ip,oid) SELECT Ip,round (RAND () * + 1) from Fortest;The above statement performs exceptionally fast and inserts 5W of data in an instant. You can write a script execution:#!/bin/bashi=

This article will introduce iBATIS batch data insertion to the database. I hope this article will help you. Using callback interfaces in the iBATIS framework also enables batch data operations to reduce the number of accesses to the database and improve performance. The following is an example of batch data insertion into an Oracle database using the iBATIS framework: Batch Data insertion: The Code is as follows: Copy code /*** Ibatis
