Hi monks,

Maybe it's slightly OT. The website I'm building in Catalyst has many query pages. I create a query sub to handle these all. Now I noticed this sub is more and more longer, and the structure of the code is much similar:

#pseudo code
my @calauses;
my $dbh = $c->model("TEST_DBI")->dbh()
my $sth;
if ($query_name = a){
......
# build query statement and where clauses;
......
}
  
elsif( $query_name == b)
{
.....
#ditto
.....
}
....
....
else{
#do nothing
}

$sth->prepare($statement)
........
#forward to view
.......

Any idea to make it more short and elegant? As in my brain, a database class including query method might be solve this problem. But where it be put? In model or in Controller? or even create a plugin?(though I don't even know how to create a plugin). Since I seldom(almost zero) read real(production) website code in Catalyst, there is no another idea in the brain. I hope monks could enlighten me!

Besides, would any monks tell me what advantage DBIx::Class(ORM) has? I had used it firstly as monks recommand, quickly I found it has high learning curve, and is hard to use in many join context.

now I switched to DBI, but I hope monks could point its advantage out and let me know spending much time to learning it is worthwhile.

Thanks!

UPDATE:

Thank Your Mother, SQL::Abstract is really what I want.
