10 | # FIXME |
11 | # This dialect has not been ported to the subquery-realiasing code |
12 | # that all other subquerying dialects are using. It is very possible |
13 | # that this dialect is entirely unnecessary - it is currently only |
14 | # used by ::Storage::DBI::ODBC::DB2_400_SQL which *should* be able to |
15 | # just subclass ::Storage::DBI::DB2 and use the already rewritten |
16 | # RowNumberOver. However nobody has access to this specific database |
17 | # engine, thus keeping legacy code as-is |
18 | # IF someone ever manages to test DB2-AS/400 with RNO, all the code |
19 | # in this block should go on to meet its maker |
