Document

Creates a FileInputStream by using the file descriptor fdObj, which represents an existing connection to an actual file in the file system.

Usage

From source file:Main.java

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();//from  w ww  . jav  a2s.  c  om

    ResultSet rs = stmt.executeQuery("SELECT * FROM survey");
    while (rs.next()) {
        System.out.print(rs.getString(1));
    }

    rs.close();
    stmt.close();
    conn.close();
