NAME
DBIx::Poggy::DBI - DBI subclass
DESCRIPTION
Overrides several methods in DBI. All queries are marked as async. See list of supported methods below:
METHODS
supported
These are supported: "selectrow_array" in DBI, "selectrow_arrayref" in DBI, "selectrow_hashref" in DBI, "selectall_arrayref" in DBI, "selectall_hashref" in DBI and "do" in DBI.
For example:
$pool->take->selectrow_array(
"SELECT * FROM test LIMIT 1",
)->then(sub {
my @row = @_;
...
});
See "Transactions" to learn about "begin_work", "commit" and "rollback".
not supported
These are not supported, but will be when I need them or somebody will write a patch: "selectcol_arrayref" in DBI
You don't use prepare
, bind*
, execute
or fetch*
. I have some ideas of making these work, but don't think there is urgent need to pursue.
Transactions
This module wraps "begin_work", "commit" and "rollback" methods to help handle transactions.
NOTE that behaviour is not yet defined when commiting or rolling back a transaction with active query. I just havn't decided what to do in this case. Now it's your job to make sure commit/rollback happens after all queries on the handle.
begin_work
Returns a Promise that will be resolved once transaction is committed or rejected on rollback or failed attempt to start the transaction.
commit
Takes resolution value of the transaction, commits and resolves the promise returned by "begin_work".
rollback
Takes rollback value of the transaction, commits and rejects the promise returned by "begin_work".
