Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {

    String driverName = "com.jnetdirect.jsql.JSQLDriver";
    Class.forName(driverName);//from   w w  w .  j  ava 2s.c  om

    String serverName = "127.0.0.1";
    String portNumber = "1433";
    String mydatabase = serverName + ":" + portNumber;
    String url = "jdbc:JSQLConnect://" + mydatabase;
    String username = "username";
    String password = "password";

    Connection connection = DriverManager.getConnection(url, username, password);

    // Get the fetch size of a statement
    Statement stmt = connection.createStatement();
    int fetchSize = stmt.getFetchSize();

    // Set the fetch size on the statement
    stmt.setFetchSize(100);

    // Create a result set
    ResultSet resultSet = stmt.executeQuery("SELECT * FROM my_table");

    // Change the fetch size on the result set
    resultSet.setFetchSize(100);
