I am trying to execute a simple query but i get hilarious error. I really don’t know how to resolve this. Have someone encountered something similar?

PreparedStatement stmt;

if (userId == null) {
  stmt = DatabaseConnection.getConnection().prepareStatement(
    "UPDATE USERS SET IS_LOGGED = ?");
  stmt.setBoolean(1, isLogged);
} else {
  stmt = DatabaseConnection.getConnection().prepareStatement(
    "UPDATE USERS SET IS_LOGGED = ? WHERE USER_ID = ?");
    stmt.setBoolean(1, isLogged);
    stmt.setInt(2, userId);
}

CommonInterface.LOGGER.info(stmt.toString());
stmt.executeUpdate();

INFO: prep1022: UPDATE USERS SET IS_LOGGED = ? WHERE USER_ID = ? {1: FALSE, 2: 1}
org.h2.jdbc.JdbcSQLDataException: Parameter "#3" is not set [90012-224]

It happens everytime I try to execute this query, can it be a problem because of not closing the statements?
