You will have to do some more reading of the DBI docs.
They say about selectall_arrayref:
This utility method combines "prepare", "execute" and "fetchall_arrayref" into a single call. It returns a reference to an array containing a reference to an array (...snip...) for each row of data fetched.As your SQL never returns more than one row with one field, you are probably rather looking for selectrow_array:
This utility method combines "prepare", "execute" and "fetchrow_array" into a single call. If called in a list context, it returns the first row of data from the statement.So you code becomes:
How you link the first part of your code to the second part is a profond mystery to me, so I abstain from commenting.
