=head1 NAME
SQL::Translator::Producer::Oracle - Oracle SQL producer
This option remove the primary key and other key constraints from the
CREATE TABLE statement and adds ALTER TABLEs at the end with it.
+=item quote_field_names
+
+Controls whether quotes are being used around column names in generated DDL.
+
+=item quote_table_names
+
+Controls whether quotes are being used around table, sequence and trigger names in
+generated DDL.

+=head1 NOTES
+
+=head2 Autoincremental primary keys
+
+This producer uses sequences and triggers to autoincrement primary key
+columns, if necessary. SQLPlus and DBI expect a slightly different syntax
+of CREATE TRIGGER statement. You might have noticed that this
+producer returns a scalar containing all statements concatenated by
+newlines or an array of single statements depending on the context
+(scalar, array) it has been called in.
+
+SQLPlus expects following trigger syntax:
+
+ CREATE OR REPLACE TRIGGER ai_person_id
+ BEFORE INSERT ON person
+ FOR EACH ROW WHEN (
+ new.id IS NULL OR new.id = 0
+ )
+ BEGIN
+ SELECT sq_person_id.nextval
+ INTO :new.id
+ FROM dual;
+ END;
+ /
+
+Whereas if you want to create the same trigger using L<DBI/do>, you need
+to omit the last slash:
+
+ my $dbh = DBI->connect('dbi:Oracle:mysid', 'scott', 'tiger');
+ $dbh->do("
+ CREATE OR REPLACE TRIGGER ai_person_id
+ BEFORE INSERT ON person
+ FOR EACH ROW WHEN (
+ new.id IS NULL OR new.id = 0
+ )
+ BEGIN
+ SELECT sq_person_id.nextval
+ INTO :new.id
+ FROM dual;
+ END;
+ ");
+
+If you call this producer in array context, we expect you want to process
+the returned array of statements using L<DBI> like
+L<DBIx::Class::Schema/deploy> does.
+
+To get this working we removed the slash in those statements in version
+0.09002 of L<SQL::Translator> when called in array context. In scalar
+context the slash will be still there to ensure compatibility with SQLPlus.
