...

# Set max length of varchar columns used to emulate the array data type
Rose::DB::MariaDB->max_array_characters(128);

$db = Rose::DB->new; # $db is really a Rose::DB::MariaDB-derived object
...

DESCRIPTION

Rose::DB blesses objects into a class derived from Rose::DB::MariaDB when the driver is "mariadb". This mapping of driver names to class names is configurable. See the documentation for Rose::DB's new() and driver_class() methods for more information.

This class cannot be used directly. You must use Rose::DB and let its new() method return an object blessed into the appropriate class for you, according to its driver_class() mappings.

Only the methods that are new or have different behaviors than those in Rose::DB are documented here. See the Rose::DB documentation for the full list of methods.

CLASS METHODS

coerce_autoincrement_to_serial [BOOL]

Get or set a boolean value that indicates whether or not "auto-increment" columns will be considered to have the column type "serial." If true, "integer" columns are coerced to the "serial" column type, and "bigint" columns use the "bigserial" column type. The default value is true.

This setting comes into play when Rose::DB::Object::Loader is used to auto-create column metadata based on an existing database schema.

max_array_characters [INT]

Get or set the maximum length of varchar columns used to emulate the array data type. The default value is 255.

MariaDB does not have a native "ARRAY" data type, but this data type can be emulated using a "VARCHAR" column and a specially formatted string. The formatting and parsing of this string is handled by the format_array and parse_array object methods. The maximum length limit is honored by the format_array object method.

max_interval_characters [INT]

Get or set the maximum length of varchar columns used to emulate the interval data type. The default value is 255.

MariaDB does not have a native "interval" data type, but this data type can be emulated using a "VARCHAR" column and a specially formatted string. The formatting and parsing of this string is handled by the format_interval and parse_interval object methods. The maximum length limit is honored by the format_interval object method.

OBJECT METHODS

mariadb_auto_reconnect [BOOL]

Get or set the mariadb_auto_reconnect database handle attribute. This is set directly on the dbh, if one exists. Otherwise, it will be set when the dbh is created. If no value for this attribute is defined (the default) then it will not be set when the dbh is created, deferring instead to whatever default value DBD::MariaDB chooses.

Returns the value of this attribute in the dbh, if one exists, or the value that will be set when the dbh is next created.
