This should be simple but I can't seem to figure it out. I can place data in my MySQL DB but can't figure out how to get the info back out and loaded into useable variables.

For this example my table is called "testtable" and it has been loaded with these simple records "id", "username", and "email". I want to check "testtable" for the existence of a particular email address, and if found I want the corresponding "username" to be loaded into a variable that I can use elsewhere in the program. If I use this SELECT command:

$sth = $dbh->do("SELECT username FROM testtable WHERE email = 'myname@mydomain.com'");

and then print $sth it returns "1". This apears to represent the number of matches. If no match is found it returns "0E0"; I don't know what OEO is but assume it means something like NULL. Printing "$username" returns nothing.

How do I get the username into a variable that I can use?

Thanks! :thumbsup:

After I posted I continued to search the web for the answer and found some terrific tutorials at Perl Monks. I know I'm not the only newbie and others may benefit from this info so here is a link to my answer.
