-sub _is_case_sensitive {
- my $self = shift;
+Most MSSQL databases use C<CI> (case-insensitive) collation, for this reason
+generated column names are lower-cased as this makes them easier to work with
+in L<DBIx::Class>.
- return $self->case_sensitive_collation ? 1 : 0;
-}
+We attempt to detect the database collation at startup, and set the column
+lowercasing behavior accordingly, as lower-cased column names do not work on
+case-sensitive databases.
+
+To manually control case-sensitive mode, put:
+
+ preserve_case => 1|0
+
+in your Loader options.
+
+See L<preserve_case|DBIx::Class::Schema::Loader::Base/preserve_case>.
+
+B<NOTE:> this option used to be called C<case_sensitive_collation>, but has
+been renamed to a more generic option.
