DBIx::Handler - fork-safe and easy transaction handling DBI handler


  use DBIx::Handler;
  my $handler = DBIx::Handler->new($dsn, $user, $pass, $opts);
  my $dbh = $handler->dbh;


DBIx::Handler is fork-safe and easy transaction handling DBI handler.

DBIx::Hanler provide scope base transaction, fork safe dbh handling, simple.


my $handler = DBIx::Handler->new($dsn, $user, $pass, $opts);

get database handling instance.

my $handler = DBIx::Handler->connect($dsn, $user, $pass, $opts);

connect method is new methos alias.

my $dbh = $handler->dbh;

get fork safe DBI handle.


disconnect current database handle.

my $txn_guard = $handler->txn_scope

Creates a new transaction scope guard object.

    do {
        my $txn_guard = $handler->txn_scope;
            # some process

If an exception occurs, or the guard object otherwise leaves the scope before $txn->commit is called, the transaction will be rolled back by an explicit "txn_rollback" call. In essence this is akin to using a "txn_begin"/"txn_commit" pair, without having to worry about calling "txn_rollback" at the right places. Note that since there is no defined code closure, there will be no retries and other magic upon database disconnection.

$txn_manager = $handler->txn_manager

Get the DBIx::TransactionManager instance.


start new transaction.


commit transaction.


rollback transaction.


are you in transaction?

my @result = $handler->txn($coderef);

execute $coderef in auto transaction scope.

begin transaction before $coderef execute, do $coderef with database handle, after commit or rollback transaciont.

  $handler->txn(sub {
      my $dbh = shift;

equals to:

      my $dbh = $handler->dbh;
my @result = $handler->run($coderef);

exexute $coderef.

  my $rs = $handler->run(sub {
      my $dbh = shift;


  my @result = $handler->run(sub {
      my $dbh = shift;
my $sth = $handler->query($sql, [\@bind | \%bind]);

exexute query. return database statement handler.


set result_class package name.

this result_class use to be create query method response object.


inject sql comment when trace_query is true.
