=head1 DESCRIPTION |
787
|
|
|
|
|
|
|
|
788
|
|
|
|
|
|
|
L<Rose::DB> blesses objects into a class derived from L<Rose::DB::Pg> when the L<driver|Rose::DB/driver> is "pg". This mapping of driver names to class names is configurable. See the documentation for L<Rose::DB>'s L<new()|Rose::DB/new> and L<driver_class()|Rose::DB/driver_class> methods for more information. |
789
|
|
|
|
|
|
|
|
790
|
|
|
|
|
|
|
This class cannot be used directly. You must use L<Rose::DB> and let its L<new()|Rose::DB/new> method return an object blessed into the appropriate class for you, according to its L<driver_class()|Rose::DB/driver_class> mappings. |
791
|
|
|
|
|
|
|
|
792
|
|
|
|
|
|
|
Only the methods that are new or have different behaviors than those in L<Rose::DB> are documented here. See the L<Rose::DB> documentation for the full list of methods. |

799
|
|
|
|
|
|
|
|
800
|
|
|
|
|
|
|
Get or set the boolean value that determines whether or not dates are assumed to be in european dd/mm/yyyy format. The default is to assume US mm/dd/yyyy format (because this is the default for PostgreSQL). |
801
|
|
|
|
|
|
|
|
802
|
|
|
|
|
|
|
This value will be passed to L<DateTime::Format::Pg> as the value of the C<european> parameter in the call to the constructor C<new()>. This L<DateTime::Format::Pg> object is used by L<Rose::DB::Pg> to parse and format date-related column values in methods like L<parse_date|Rose::DB/parse_date>, L<format_date|Rose::DB/format_date>, etc. |

805
|
|
|
|
|
|
|
|
806
|
|
|
|
|
|
|
Advance the sequence named SEQUENCE and return the new value. Returns undef if there was an error. |

|
|
|

|
|
|
|

|
|

809
|
|
|
|
|
|
|
|
810
|
|
|
|
|
|
|
Get or set the time zone used by the database server software. TZ should be a time zone name that is understood by L<DateTime::TimeZone>. The default value is "floating". |
811
|
|
|
|
|
|
|
|
812
|
|
|
|
|
|
|
This value will be passed to L<DateTime::Format::Pg> as the value of the C<server_tz> parameter in the call to the constructor C<new()>. This L<DateTime::Format::Pg> object is used by L<Rose::DB::Pg> to parse and format date-related column values in methods like L<parse_date|Rose::DB/parse_date>, L<format_date|Rose::DB/format_date>, etc. |
813
|
|
|
|
|
|
|
|
814
|
|
|
|
|
|
|
See the L<DateTime::TimeZone> documentation for acceptable values of TZ. |

817
|
|
|
|
|
|
|
|
818
|
|
|
|
|
|
|
Get or set the L<pg_enable_utf8|DBD::Pg/pg_enable_utf8> database handle attribute. This is set directly on the L<dbh|Rose::DB/dbh>, if one exists. Otherwise, it will be set when the L<dbh|Rose::DB/dbh> is created. If no value for this attribute is defined (the default) then it will not be set when the L<dbh|Rose::DB/dbh> is created, deferring instead to whatever default value L<DBD::Pg> chooses. |
819
|
|
|
|
|
|
|
|
820
|
|
|
|
|
|
|
Returns the value of this attribute in the L<dbh|Rose::DB/dbh>, if one exists, or the value that will be set when the L<dbh|Rose::DB/dbh> is next created. |
821
|
|
|
|
|

|
|
822
|
|
|

See the L<DBD::Pg|DBD::Pg/pg_enable_utf8> documentation to learn more about this attribute. |

825
|
|
|
|
|
|
|
|
826
|
|
|
|
|
|
|
Get or set the SSL mode of the connection. Valid values for MODE are C<disable>, C<allow>, C<prefer>, and C<require>. This attribute is used to build the L<DBI> L<dsn|Rose::DB/dsn>. Setting it has no effect until the next L<connect|Rose::DB/connect>ion. See the L<DBD::Pg|DBD::Pg/connect> documentation to learn more about this attribute. |

|
|
|
|
|
|
|
Given a reference to an array or a list of values, return a string formatted according to the rules of PostgreSQL's "ARRAY" column type. Undef is returned if ARRAYREF points to an empty array or if LIST is not passed. |

Given a L<DateTime::Duration> object, return a string formatted according to the rules of PostgreSQL's "INTERVAL" column type. If DURATION is undefined, a L<DateTime::Duration> object, a valid interval keyword (according to L<validate_interval_keyword|Rose::DB/validate_interval_keyword>), or if it looks like a function call (matches C</^\w+\(.*\)$/>) and L<keyword_function_calls|Rose::DB/keyword_function_calls> is true, then it is returned unmodified. |

843
|
|
|
|
|
|
|
|
844
|
|
|
|
|
|
|
Parse STRING and return a reference to an array. STRING should be formatted according to PostgreSQL's "ARRAY" data type. Undef is returned if STRING is undefined. |

|

|
|
|

|
|
|
|
|
|
|
Parse STRING and return a L<DateTime::Duration> object. STRING should be formatted according to the PostgreSQL native "interval" (years, months, days, hours, minutes, seconds) data type. |
849
|
|
|
|
|
|
|
|
850
|
|
|
|
|
|
|
If STRING is a L<DateTime::Duration> object, a valid interval keyword (according to L<validate_interval_keyword|Rose::DB/validate_interval_keyword>), or if it looks like a function call (matches C</^\w+\(.*\)$/>) and L<keyword_function_calls|Rose::DB/keyword_function_calls> is true, then it is returned unmodified. Otherwise, undef is returned if STRING could not be parsed as a valid "interval" value. |
