Hi there,
I am wondering if it would be possible to get the amount of different values
in one sql command.
E.g.:
field age: 0,3,5,5,2,3
Sql querry should return how often 3 occurs. Which would be 2. And as well
the other values... 1 for agestructure 2 becuase it occures only once.
I wrote following querry
$stmt="
SELECT COUNT(*) AS c
FROM $T5
WHERE age = 4
";
$row = db_get_row2($stmt);
$age_4 = $row->c;
This returns only the value for 4. To get all values (10 different ones) I
would have to make 10 querrys, right?
Is there a faster way?
Thanx for any help,
Andy
