Class::DBI, Class::DBI::AbstractSearch, and Oracle to_date
I'm trying to produce the following SQL using CDBI:
select * from mytable
where ref = "foo"
and to_date(received_date, 'DD-MM-YYYY') < to_date('01-04-2011', 'DD-MM-YYYY')
The closest syntax I can think of is:
mycdbi->search_where({
ref => 'foo',
received_date => { '<' => ["to_date(?, 'DD-MM-YYYY')", '01-04-2011'] }
});
However that's not converting the column mytable.received_date using Oracle function to_date.
So what's the correct way to do it?
Ps: please don't say use DBIC as the code needs to stay i开发者_Go百科n CDBI.
thanks!
Might be easiest to just use retrieve_from_sql
and do it by hand:
my @things = mycdbi->retrieve_from_sql(qq{
ref = 'foo'
AND to_date(received_date, 'DD-MM-YYYY') < to_date('01-04-2011', 'DD-MM-YYYY')
});
I usually end up pushing the ORMs out of the way for any instantiation more complicated than my $thing = Thing->retrieve(x)
, I already know SQL so I don't need to learn yet another API that tries to implement SQL and usually does so rather poorly.
