Let’s see how we can perform batch insert in Java using JDBC APIs. Although you might already knew this, I will try to explain the basic to a bit complex scenarios. In this note, we will see how we can use JDBC APIs likeStatementandPreparedStatementto insert data in any database in ...

int executeUpdate(String sqlString):用于执行 DML(INSERT、UPDATE 或 DELETE等)语句以及 DDL(CREATE、DROP等); boolean execute(String sqlString):用于执行返回多个结果集、多个更新计数或二者组合的语句。多数程序员不会需要该高级功能。 具体实现的代码: ...
1.在Java语言中,使用Statement对象的executeUpdate()方法,来完成数据库的数据处理操作。executeUpdate()方法是用于执行给定的SQL语句,如INSERT、UPDATE或DELETE语句,该方法的返回值是一个整数,该整数代表的意思是数据库受到影响的行数。 2.操作数据库实现的基本步骤,如下所示: ...
INSERT INTO `student` VALUES (6, '魏红', 23, 46); CREATE DATABASE `test` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; CREATE TABLE `student` ( `id` INT NOT NULL AUTO_INCREMENT , `name` VARCHAR(20) NOT NULL , `age` INT NOT NULL , `score` DOUBLE NOT NULL , PRIMARY KEY...
