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: CODE
$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: CODE select result, count(*) AS Number
from table
GROUP BY result
ORDER 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.

The Only Reason I Choose Ms Sql Server Rather Than Mysql

in t-sql syntax, like query in query is not fully supported - Does not have today SQL features like
