Question

I’m saving a string from PHP to MySQL like this..

$groupid = "13, 14, 15, 16"
$write = mysql_query("INSERT INTO table VALUES ('','$groupid')");

I’m then trying to extract data from the table if $a = “15”

$extract = mysql_query("SELECT * FROM table WHERE ustaffid='$ustaffid' AND groupid='$a'");

How can I easily match what’s in $groupid to $a, while extracting it? Can I do that with MySQL?

Answer 1

You can use the find_in_set function here.

SELECT * 
    FROM table 
    WHERE ustaffid='$ustaffid' 
        AND FIND_IN_SET('$a', groupid) > 0
