6 DBIx::Class::Storage::DBI::Oracle::WhereJoins - Oracle joins in WHERE
7 syntax support (instead of ANSI).
8
10 This module was originally written to support Oracle < 9i where ANSI
11 joins weren't supported at all, but became the module for Oracle >= 8
12 because Oracle's optimising of ANSI joins is horrible.
13
15 DBIx::Class should automagically detect Oracle and use this module with
16 no work from you.
17
19 This class implements Oracle's WhereJoin support. Instead of:
20
21 SELECT x FROM y JOIN z ON y.id = z.id
22
23 It will write:
24
25 SELECT x FROM y, z WHERE y.id = z.id
26
27 It should properly support left joins, and right joins. Full outer
28 joins are not possible due to the fact that Oracle requires the entire
29 query be written to union the results of a left and right join, and by
30 the time this module is called to create the where query and table
31 definition part of the SQL query, it's already too late.
32
34 See DBIx::Class::SQLAHacks::OracleJoins for implementation details.
35
37 Does not support full outer joins. Probably lots more.
