i started this writeup earlier when i was at work ... but couldn't get it finished ( the lull in the day came to an abrupt end ).

i've been looking into easier, faster ways of generating some of my SQL queries. ( faster on the coding time, at least ). i've poked around a bit in the Class::DBI perldoc, but it looks like using it for more complicated joins ( like LEFT JOINs when they're needed ) would be almost more of a hassle than a help ...

the first place i've been looking to replace some of my SQL is actually in my INSERT/UPDATE queries. i tend to do this a lot: 

sub storeData {
   my $self = shift;
 
   my @fields = qw/ foo bar baz quid quux /;

   my $insStmt = "INSERT INTO table 
                  VALUES ( " ; 
   $insStmt .= "? " x ( scalar( @fields ) +1 );
   $insStmt .= " ) ";

   my $updStmt = "UPDATE table 
                  SET " . join( "$_ = ?, ", @fields;
   $updStmt .= "WHERE id = ? ";

    $useSql = ( $id ? $updStmt : $insStmt );

then run through all the usual prepare, execute, bind_params, etc. as needed ( working off the @fields array.

it's fairly maintainable. adding an element to @fields gets the column added to the ins/upd statements, but I'm starting to wonder how much easier it could get.

would Class::DBI be an appropriate solution?
