向数据库发送多条sql语句
create database batch
use batch
create table batch_table(
id int primary key auto_increment,
name varchar(20)
)
insert into batch_table values(null,”aaa”)
insert into batch_table values(null,”bbb”)
insert into batch_table values(null,”ccc”)
Statement方式执行批处理:
优点:可以执行多条不同结构的sql语句
缺点:没有使用预编译机制,效率低下
import java.sql.Connection; import java.sql.DriverManager; import java.sql.Statement; public class JDBCBatchTest { public static void main(String[] args) { try { // 注册数据库驱动 //DriverManager.registerDriver(new Driver()); //使用反射的方式 Class.forName("com.mysql.jdbc.Driver"); //获取数据库连接,导包的时候,注意要导java.sql下的,面向接口编程 Connection conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/java","root","root"); //获取传输器对象 Statement statement=conn.createStatement(); statement.addBatch("create database batch"); statement.addBatch("use batch"); statement.addBatch("create table batch_table(id int primary key auto_increment,name varchar(20))"); statement.addBatch("insert into batch_table values(null,'aaa')"); statement.addBatch("insert into batch_table values(null,'bbb')"); statement.addBatch("insert into batch_table values(null,'ccc')"); statement.executeBatch(); } catch (Exception e) { e.printStackTrace(); } } }
