Fellow Monastians:

As I pull in records from a flat, tab-delimited file, I parse it into an AoH, one array element for each record (I have to go through this preliminary step because I have to test a few of the hash values for legitimacy).

In the end, I loop through the array and copy each of the hashes into a single hash for insertion into my DB table.

I thought I could do this in just one step:

for ( 0 .. $#fields) {
   %sql_data = $fields[$_];
  ... insert into DB ...
}

but even with Data Dumping I couldn't figure out why it wasn't working. So, as a work-around until I could post it here, I did a very convoluted:

for ( 0 .. $#fields) {
   $sql_data{'description'}   = $fields[$_]{'description'};
   $sql_data{'billing_code'}  = $fields[$_]{'billing_code'};
   $sql_data{'user_id'}       = $fields[$_]{'user_id'};
   $sql_data{'project_id'}    = $fields[$_]{'project_id'};
   $sql_data{'bad_proj'}      = $fields[$_]{'bad_proj'};
   $sql_data{'bad_bill'}      = $fields[$_]{'bad_bill'};
   $sql_data{'bad_user'}      = $fields[$_]{'bad_user'};

   $stmt = qq/INSERT INTO temp_sheet (/ . join(',', keys %sql_data ) .
+ qq/) 
               VALUES (/ . join(',', ('?') x keys %sql_data ) . qq/)/;
+   

   $sth = $dbh->prepare($stmt);
   $sth->execute(values %sql_data );
}

I know this could be better, but I just can't make it work. What am I totally not seeing. Thanks in advance.

Yes, I'm using strict.
