How Expensive Are Calls To Mysql?

Hi,

I would like to sharea design I am currently using and have you all tell me if it is an optimal way of doing things.

First, here is a table (named schedule) in my MySQL database:

game_ID Result
1 W
2 L
3 W
4 T

In my PHP code I want to get the number of wins (W), losses (L), and ties (T). Here is how I did it:

$wins_sql = "SELECT * FROM schedule WHERE result = 'W'";$loss_sql = "SELECT * FROM schedule WHERE result ='L'";$tie_sql = "SELECT * FROM schedule WHERE result ='T'";$num_loss = mysql_num_rows(mysql_query($loss_sql, $conn));$num_wins = mysql_num_rows(mysql_query($wins_sql, $conn));$num_tie = mysql_num_rows(mysql_query($tie_sql, $conn));echo "Overall Record: $num_wins - $num_loss - $num_tie\n";

Are using three different sql statements the best way to do this? If not, can you please provide an example of what would be better? Thanks!

I think you want to do something using GROUP BY:

select result, count(*) AS Numberfrom tableGROUP BY resultORDER BY Number;

You don't need Number as a field in your table - you're specifying another value to use in your SQL with the AS command.

Yeah!!! That works from a MySQL view point, but I'm not suer what to do with the returned resutlts from a PHP standpoint.
