hi frnz, I have a problem with mysql group by... tired of looking on the google so finally posting it here... my table structure is as showing above. I am using the following query...

$sql2w=executeQuery("select * from logo group by cl  ");
    while($line2=mysql_fetch_array($sql2)){ 
    echo $line2['typ'];
}

I am getting 1 and 2 in the result, but I want the result in this format.. 1,4,7 and 2,4,8 in string or in array format...

I hope I am clear what I want...

I am only getting the first row values of "typ" column but I want all rows values in array after grouping the "cl" column..

Thanks in advance

Answer 1

Use GROUP_CONCAT() :

SELECT cl, GROUP_CONCAT(typ) FROM logo GROUP BY cl

See it on sqlfiddle .
