61 This class implements base Oracle support. The subclass
62 DBIx::Class::Storage::DBI::Oracle::WhereJoins is for "(+)" joins in
63 Oracle versions before 9.0.
64
66 get_autoinc_seq
67 Returns the sequence name for an autoincrement column
68 datetime_parser_type
70 This sets the proper DateTime::Format module for use with
71 DBIx::Class::InflateColumn::DateTime.
72 connect_call_datetime_setup
74 Used as:
75 on_connect_call => 'datetime_setup'
77 In connect_info to set the session nls date, and timestamp values for
79 use with DBIx::Class::InflateColumn::DateTime and the necessary
80 environment variables for DateTime::Format::Oracle, which is used by
81 it.
82 Maximum allowable precision is used, unless the environment variables
84 have already been set.
85 These are the defaults used:
87 $ENV{NLS_DATE_FORMAT} ||= 'YYYY-MM-DD HH24:MI:SS';
89 $ENV{NLS_TIMESTAMP_FORMAT} ||= 'YYYY-MM-DD HH24:MI:SS.FF';
90 $ENV{NLS_TIMESTAMP_TZ_FORMAT} ||= 'YYYY-MM-DD HH24:MI:SS.FF TZHTZM';
91 To get more than second precision with
93 DBIx::Class::InflateColumn::DateTime for your timestamps, use something
94 like this:
95 use Time::HiRes 'time';
97 my $ts = DateTime->from_epoch(epoch => time);
98 relname_to_table_alias
100 DBIx::Class uses DBIx::Class::Relationship names as table aliases in
101 queries.
102 Unfortunately, Oracle doesn't support identifiers over 30 chars in
104 length, so the DBIx::Class::Relationship name is shortened and appended
105 with half of an MD5 hash.
106 See "relname_to_table_alias" in DBIx::Class::Storage::DBI.
108 with_deferred_fk_checks
110 Runs a coderef between:
111 alter session set constraints = deferred
113 ...
114 alter session set constraints = immediate
115 to defer foreign key checks.
117 Constraints must be declared "DEFERRABLE" for this to work.
119
121 Following additional attributes can be used in resultsets.
122 connect_by or connect_by_nocycle
124 Value: \%connect_by
125 A hashref of conditions used to specify the relationship between parent
127 rows and child rows of the hierarchy.
128 connect_by => { parentid => 'prior personid' }
130 # adds a connect by statement to the query:
132 # SELECT
133 # me.persionid me.firstname, me.lastname, me.parentid
134 # FROM
135 # person me
136 # CONNECT BY
137 # parentid = prior persionid
138 connect_by_nocycle => { parentid => 'prior personid' }
141 # adds a connect by statement to the query:
143 # SELECT
144 # me.persionid me.firstname, me.lastname, me.parentid
145 # FROM
146 # person me
147 # CONNECT BY NOCYCLE
148 # parentid = prior persionid
149 start_with
151 Value: \%condition
152 A hashref of conditions which specify the root row(s) of the hierarchy.
154 It uses the same syntax as "search" in DBIx::Class::ResultSet
156 start_with => { firstname => 'Foo', lastname => 'Bar' }
158 # SELECT
160 # me.persionid me.firstname, me.lastname, me.parentid
161 # FROM
162 # person me
163 # START WITH
164 # firstname = 'foo' and lastname = 'bar'
165 # CONNECT BY
166 # parentid = prior persionid
167 order_siblings_by
169 Value: ($order_siblings_by | \@order_siblings_by)
170 Which column(s) to order the siblings by.
172 It uses the same syntax as "order_by" in DBIx::Class::ResultSet
174 'order_siblings_by' => 'firstname ASC'
176 # SELECT
178 # me.persionid me.firstname, me.lastname, me.parentid
179 # FROM
180 # person me
181 # CONNECT BY
182 # parentid = prior persionid
183 # ORDER SIBLINGS BY
184 # firstname ASC
