How to get row count using ResultSet in Java?

Question

I\'m trying to create a simple method that receives a ResultSet as a parameter and returns an int that contains the row count of the ResultSet. Is this a valid way of doing

Answer 1

Following two options worked for me:

1) A function that returns the number of rows in your ResultSet.

private int resultSetCount(ResultSet resultSet) throws SQLException{
    try{
        int i = 0;
        while (resultSet.next()) {
            i++;
        }
        return i;
    } catch (Exception e){
       System.out.println("Error getting row count");
       e.printStackTrace();
    }
    return 0;
}

2) Create a second SQL statement with the COUNT option.
