my $string = Foo::Bar->dsn;
The dsn accessor returns the dbi connection string used to connect to the SQLite database as a string.
my $handle = Foo::Bar->dbh;
To reliably prevent potential SQLite deadlocks resulting from multiple connections in a single process, each ORLite package will only ever maintain a single connection to the database.
During a transaction, this will be the same (cached) database handle.
Although in most situations you should not need a direct DBI connection handle, the dbh method provides a method for getting a direct connection in a way that is compatible with ORLite's connection management.
Please note that these connections should be short-lived, you should never hold onto a connection beyond the immediate scope.
The transaction system in ORLite is specifically designed so that code using the database should never have to know whether or not it is in a transation.
Because of this, you should never call the ->disconnect method on the database handles yourself, as the handle may be that of a currently running transaction.
Further, you should do your own transaction management on a handle provided by the <dbh> method.
In cases where there are extreme needs, and you absolutely have to violate these connection handling rules, you should create your own completely manual DBI->connect call to the database, using the connect string provided by the dsn method.
The dbh method returns a DBI::db object, or throws an exception on error.
The selectall_arrayref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.
It takes the same parameters and has the same return values and error behaviour.
The selectall_hashref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.
It takes the same parameters and has the same return values and error behaviour.
The selectcol_arrayref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.
It takes the same parameters and has the same return values and error behaviour.
The selectrow_array method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.
It takes the same parameters and has the same return values and error behaviour.
The selectrow_arrayref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.
It takes the same parameters and has the same return values and error behaviour.
The selectrow_hashref method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction.
It takes the same parameters and has the same return values and error behaviour.
The prepare method is a direct wrapper around the equivalent DBI method, but applied to the appropriate locally-provided connection or transaction
It takes the same parameters and has the same return values and error behaviour.
In general though, you should try to avoid the use of your own prepared statements if possible, although this is only a recommendation and by no means prohibited.
# Get the user_version for the schema
my $version = Foo::Bar->pragma('user_version');
The pragma method provides a convenient method for fetching a pragma for a datase. See the SQLite documentation for more details.
ORDB::CPANTS is based on ORLite 1.18.
Documentation created by ORLite::Pod 0.06.
