NAME
Acrux::DBI - Database independent interface for Acrux applications
SYNOPSIS
use Acrux::DBI;
DESCRIPTION
Database independent interface for Acrux applications
new
my $dbi = Acrux::DBI->new( $db_url );
my $dbi = Acrux::DBI->new( $db_url, { ... options ... });
my $dbi = Acrux::DBI->new( $db_url, ... options ...);
Build new Acrux::DBI object
Options:
- autoclean
-
This options turns on auto disconnecting on DESTROY phase
See also list of default options in "options"
METHODS
This class implements the following methods
begin
$dbi->begin;
# ...
$dbi->commit; # ..or $dbi->rollback
This is a transaction method!
This method marks the starting point for the start of a transaction
eval {
$dbi->begin;
$db->query('insert into test values (?)', 'Foo');
$db->query('insert into test values (?)', 'Bar');
$dbi->commit;
};
die $@ if $@;
See slso "commit", "rollback"
cache
my $cache = $dbi->cache;
Returns the Mojo::Cache object
cachekey
my $cachekey = $dbi->cachekey;
Returns the key name of the cached connect (See "connect_cached")
cleanup
$dbi = $dbi->cleanup;
This internal method to cleanup database handler
commit
$dbi->begin;
# ...
$dbi->commit;
This is a transaction method!
This method accepts all changes to the database and marks the end point for the transaction to complete
See also "begin", "rollback"
connect
my $dbi = $dbi->connect;
die $dbi->error if $dbi->error;
This method makes a connection to the database
connect_cached
my $dbi = $dbi->connect_cached;
die $dbi->error if $dbi->error;
This method makes a cached connection to the database. See "connect_cached" in DBI for details
database
my $database = $dbi->database;
This method returns the database that will be used for generating the connection DSN This will be used as "path" in Mojo::URL
Default: none
dbh
my $dbh = $dbi->dbh;
Returns database handle used for all queries
disconnect
my $dbi = $dbi->disconnect;
This method disconnects from the database
driver
my $driver = $dbi->driver;
This is the "scheme" in Mojo::URL that will be used for generating the connection DSN
Default: sponge
dsn
my $dsn = $dbi->dsn;
This method generates the connection DSN and returns it or returns already generated earley.
err
my $err = $dbi->err;
This method just returns $DBI::err
value
errstr
my $errstr = $dbi->errstr;
This method just returns $DBI::errstr
value
error
my $error = $dbi->error;
Returns error string if occurred any errors while working with database
$dbi = $dbi->error( "error text" );
Sets new error message and returns object
host
my $host = $dbi->host;
This is the "host" in Mojo::URL that will be used for generating the connection DSN
Default: localhost
options
my $options = $dbi->options;
This method returns options that will be used for generating the connection DSN
Default: all passed options to constructor merged with system defaults:
RaiseError => 0,
PrintError => 0,
PrintWarn => 0,
password
my $password = $dbi->password;
This is the "password" in Mojo::URL that will be used for generating the connection DSN
default: none
ping
$dbi->ping ? 'OK' : 'Database session is expired';
Checks the connection to database
port
my $port = $dbi->port;
This is the "port" in Mojo::URL that will be used for generating the connection DSN
Default: none
query
my $res = $dbi->query('select * from test');
my $res = $dbi->query('insert into test values (?, ?)', @values);
Execute a blocking statement and return a Acrux::DBI::Res object with the results. You can also append a 'bind_callback' to perform binding value manually:
my $res = $dbi->query('insert into test values (?, ?)', {
bind_callback => sub {
my $sth = shift;
$sth->bind_param( ... );
}
});
reconnect
$dbi = $dbi->reconnect;
This method performs reconnecting to database and returns this object
rollback
$dbi->begin;
# ...
$dbi->rollback;
This is a transaction method!
This method discards all changes to the database and marks the end point for the transaction to complete
url
$dbi = $dbi->url('sqlite:///tmp/test.db?sqlite_unicode=1');
$dbi = $dbi->url('postgres://foo:pass@localhost/mydb?PrintError=1');
my $url = $dbi->url;
Database connect ur
The database connection URL from which all other attributes can be derived. "url"
must be specified before the first call to "connect"
is made, otherwise it will have no effect on setting the defaults.
Default: "sponge://"
transaction
my $tx = $dbi->transaction;
Begin transaction and return Acrux::DBI::Tx object, which will automatically roll back the transaction unless "commit" in Acrux::DBI::Tx has been called before it is destroyed
# Insert rows in a transaction
eval {
my $tx = $dbi->transaction;
$dbi->query( ... );
$dbi->query( ... );
$tx->commit;
};
say $@ if $@;
username
my $username = $dbi->username;
This is the "username" in Mojo::URL that will be used for generating the connection DSN
default: none
userinfo
my $userinfo = $dbi->userinfo;
This is the "userinfo" in Mojo::URL that will be used for generating the connection DSN
default: none
