Description

The following code shows how to insert text file using binary stream to database.

Example


//  w  w w . j av a2 s  .  c  o  m
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;

public class Main {
  public static void main(String[] args) throws Exception {
    Connection conn = getConnection();
    Statement stmt = conn.createStatement();


    stmt.executeUpdate("create table survey (id int, name BINARY );");

    String sql = "INSERT INTO survey (name) VALUES(?)";
    PreparedStatement pstmt = conn.prepareStatement(sql);

    // prepare small binary stream
    File smallFile = new File("yourFileName.txt");
    int smallFileLength = (int) smallFile.length();
    InputStream smallStream = (InputStream) new FileInputStream(smallFile);

    pstmt.setBinaryStream(2, smallStream, smallFileLength);
    
    // insert the data
    pstmt.executeUpdate();
    
    ResultSet rs = stmt.executeQuery("SELECT * FROM survey");
    while (rs.next()) {
        System.out.print(rs.getString(1));
    }
    
    
    rs.close();
    stmt.close();
    conn.close();
  }

  private static Connection getConnection() throws Exception {
    Class.forName("org.hsqldb.jdbcDriver");
    String url = "jdbc:hsqldb:mem:data/tutorial";

    return DriverManager.getConnection(url, "sa", "");
  }
