Mysql-connector-java-3.1.10 is a JDBC connector for MYSQL database. MYSQL provides LOAD DATA INFILE utility to import data from files like csv, txt or xls into database tables.

The example below imports data from .txt file into table.

temp.txt file is a tab separated file:

"1 string"      100
"2 string"      102
"3 string"      104
"4 string"      106
testtable structure
CREATE TABLE testtable
(id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
text varchar(45) NOT NULL,
price integer not null);
 import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;
import java.sql.ResultSet;
import java.sql.SQLException;

public class automateImport
{
    public static void main(String[] args) 
    {
        DBase db = new DBase();
        Connection conn = db.connect(
    "jdbc:mysql://localhost:3306/test","root","caspian");
        db.importData(conn,args[0]);
    }

}

class DBase
{
    public DBase()
    {
    }

    public Connection connect(String db_connect_str, 
  String db_userid, String db_password)
    {
        Connection conn;
        try 
        {
            Class.forName(  
    "com.mysql.jdbc.Driver").newInstance();

            conn = DriverManager.getConnection(db_connect_str, 
    db_userid, db_password);
        
        }
        catch(Exception e)
        {
            e.printStackTrace();
            conn = null;
        }

        return conn;    
    }
    
    public void importData(Connection conn,String filename)
    {
        Statement stmt;
        String query;

        try
        {
            stmt = conn.createStatement(
    ResultSet.TYPE_SCROLL_SENSITIVE,
    ResultSet.CONCUR_UPDATABLE);

            query = "LOAD DATA INFILE '"+filename+
    "' INTO TABLE testtable (text,price);";

            stmt.executeUpdate(query);
                
        }
        catch(Exception e)
        {
            e.printStackTrace();
            stmt = null;
        }
    }
};

If you want to import a CSV file, you can use the following query:

query = "LOAD DATA INFILE '"+filename+"' INTO TABLE testtable  FIELDS
 TERMINATED BY ',' (text,price)";
