I have a table with some columns (see the pic below):
My Table:
I'd like to count values in that columns (how many "ok" and "no" I have in column over05, over15, etc etc) using some filters (ie best_bets between 1.20 and 1.50) and show them using php
Now I can do a count just for a column using code below:
$result=mysql_query("SELECT count(over15) as total from risultati WHERE over15 = 'OK' AND best_bets >= 1.15 AND best_bets <= 1.50");
$data=mysql_fetch_assoc($result);
echo $data['total'];
but I'd like to do it for more columns
Regards
EDIT:I tried in this way, but it's not working:
$result=mysql_query("SELECT SUM(CASE WHEN over05 = 'OK' THEN 1 ELSE 0 END) AS OK_05,
SUM(CASE WHEN over15 = 'OK' THEN 1 ELSE 0 END) AS OK_15,
SUM(CASE WHEN over25 = 'OK' THEN 1 ELSE 0 END) AS OK_25,
SUM(CASE WHEN over35 = 'OK' THEN 1 ELSE 0 END) AS OK_35,
SUM(CASE WHEN over45 = 'OK' THEN 1 ELSE 0 END) AS OK_45
FROM risultati
WHERE best_bets BETWEEN 1.15 AND 1.5O");
$data=mysql_fetch_assoc($result);
echo $data['OK_15'];
echo $data['OK_25'];
echo $data['OK_35'];
echo $data['OK_45'];
edit2: I also tried in another way, but nothing:
$result=mysql_query("SELECT SUM(CASE WHEN over05 = 'OK' THEN 1 ELSE 0 END) AS OK_05,
SUM(CASE WHEN over15 = 'OK' THEN 1 ELSE 0 END) AS OK_15,
SUM(CASE WHEN over25 = 'OK' THEN 1 ELSE 0 END) AS OK_25,
SUM(CASE WHEN over35 = 'OK' THEN 1 ELSE 0 END) AS OK_35,
SUM(CASE WHEN over45 = 'OK' THEN 1 ELSE 0 END) AS OK_45
FROM risultati
WHERE best_bets BETWEEN 1.15 AND 1.5O");
while ($row = mysql_fetch_assoc($result))
{
echo $row['OK_05'];
echo $row['OK_15'];
echo $row['OK_25'];
echo $row['OK_35'];
echo $row['OK_45'];
}
Use condtional aggregation:
SELECT SUM(CASE WHEN over05 = 'OK' THEN 1 ELSE 0 END) AS OK_05,
SUM(CASE WHEN over15 = 'OK' THEN 1 ELSE 0 END) AS OK_15,
SUM(CASE WHEN over25 = 'OK' THEN 1 ELSE 0 END) AS OK_25,
SUM(CASE WHEN over35 = 'OK' THEN 1 ELSE 0 END) AS OK_35,
SUM(CASE WHEN over45 = 'OK' THEN 1 ELSE 0 END) AS OK_45
FROM risultati
WHERE best_bets BETWEEN 1.15 AND 1.5O -- or whatever restrictions you want
This approach allows you to gather stats for all your age columns in a single query, whereas putting the column check for 'OK' limits to a single column in one query.
