The two methods which you describe above for dereferencing a hashref structure are correct as per perlref and should work.

A couple of other debugging points which you may want to consider:

• Are you sure that you are actually getting a return value for the DBI database query issued? If there are no matching rows or an error occurs, then fetchrow_hashref will return undef - After calling fetchrow_hashref, you should check $sth->err to ensure that the undef returned is not the result of DBI error. Alternatively, you can confirm that you are indeed having a hashref structure returned by calling ref( $myref ), the result of which should be HASH.
• If you have no luck with examining the actual data structure returned by fetchrow_hashref as described above, you may want to paste a little bit more of your surrounding code with some comments on arguments and database structure.

 

perl -e 's&&rob@cowsnet.com.au&&&split/[@.]/&&s&.com.&_&&&print'
