NAME ORDB::CPANRT - An ORLite-based ORM database for rt.cpan.org DESCRIPTION ORDB::CPANRT is a light weight ORM module that gives you direct access to an official exported copy of the most important ticket properties of all bugs reported in . It automatically updates as needed as the export files on the RT website are updated. METHODS dsn my $string = ORDB::CPANRT->dsn; The "dsn" accessor returns the DBI connection string used to connect to the SQLite database as a string. dbh my $handle = ORDB::CPANRT->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 connection management in ORLite. Please note that these connections should be short-lived, you should never hold onto a connection beyond your 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 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. begin ORDB::CPANRT->begin; The "begin" method indicates the start of a transaction. In the same way that ORLite allows only a single connection, likewise it allows only a single application-wide transaction. No indication is given as to whether you are currently in a transaction or not, all code should be written neutrally so that it works either way or doesn't need to care. Returns true or throws an exception on error. rollback The "rollback" method rolls back the current transaction. If called outside of a current transaction, it is accepted and treated as a null operation. Once the rollback has been completed, the database connection falls back into auto-commit state. If you wish to immediately start another transaction, you will need to issue a separate ->begin call. If a transaction exists at END-time as the process exits, it will be automatically rolled back. Returns true or throws an exception on error. do ORDB::CPANRT->do( 'insert into table ( foo, bar ) values ( ?, ? )', {}, \$foo_value, \$bar_value, ); The "do" 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. selectall_arrayref 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. selectall_hashref 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. selectcol_arrayref 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. selectrow_array 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. selectrow_arrayref 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. selectrow_hashref 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. prepare 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. pragma # Get the user_version for the schema my $version = ORDB::CPANRT->pragma('user_version'); The "pragma" method provides a convenient method for fetching a pragma for a datase.
