速度比insert要快20倍。共享一下java程序操作。
package com.mysql.csv; import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.SQLException; public class Competition { static Connection conn = null; static String driver = "com.mysql.jdbc.Driver"; static String url = "jdbc:mysql://127.0.0.1:3306/nerd_1"; public static void main(String[] args) throws ClassNotFoundException, SQLException { Class.forName(driver); conn = DriverManager.getConnection(url, "root", "1234"); String sql = "LOAD DATA INFILE 'E://baidu//cp9.csv' REPLACE INTO TABLE baidu_34000_0_competition CHARACTER SET utf8 FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' ignore 1 lines"; PreparedStatement pstmt = conn.prepareStatement(sql); pstmt.execute(); conn.close(); } }批量插入需要条件具体可参考文档:http://dev.mysql.com/doc/refman/5.1/zh/sql-syntax.html#load-data |
