Java JDBC connection status

Question

I am (successfully) connecting to a database using the following:

java.sql.Connection connect = DriverManager.getConnection(
  \"jdbc:mysql://localhost/some_         


        

Answer 1

If you are using MySQL

public static boolean isDbConnected() {
    final String CHECK_SQL_QUERY = "SELECT 1";
    boolean isConnected = false;
    try {
        final PreparedStatement statement = db.prepareStatement(CHECK_SQL_QUERY);
        isConnected = true;
    } catch (SQLException | NullPointerException e) {
        // handle SQL error here!
    }
    return isConnected;
}

I have not tested with other databases. Hope this is helpful.
