Creates a Statement object that will generate ResultSet objects with the given type and concurrency.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    String driverName = "com.jnetdirect.jsql.JSQLDriver";
    Class.forName(driverName);/* w  ww  .j a  va  2  s.c  o m*/

    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);
    // Create a statement that will return updatable result sets
    Statement stmt = connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);

    // Primary key must be specified so that the result set is updatable
    ResultSet resultSet = stmt.executeQuery("SELECT col_string FROM my_table");

    int concurrency = resultSet.getConcurrency();

    if (concurrency == ResultSet.CONCUR_UPDATABLE) {
        System.out.println("Result set is updatable");
    } else {
        System.out.println("Result set is not updatable");
    }
