adderek, jim mcnamara
I've get your opinion that the DBI is faster than the 'pipe'-solution and that the way to work in Oracle much more important than the way to bring the requests upt to Oracle.
I have considered the sql*loader as a good option.
Thank you for that!
Generally speaking, I've get that the difference of involve the Oracle considerable insignificant relatively to the way of processing the Oracle staff.
So, more convenient and easy to handle (from coding side) way is reasonably more appropriate!
(I am interested in all other 'funny staff', like 'exadata', tkprof, '..developer', TOAD and 'clustered tables' and even much expressed by so wide ... referred area!
I hope that for some readers it would be a good guideline to learn Oracle tools and market.
One of the smart ways to hide information is to provide it with tones of unrelated information. )
Anyway, thank you for participation and your advance opinions!

DBIx::Class::Storage::DBI::Oracle::WhereJoins(3pm) User Contributed Perl Documentation DBIx::Class::Storage::DBI::Oracle::WhereJoins(3pm) NAME
DBIx::Class::Storage::DBI::Oracle::WhereJoins - Oracle joins in WHERE syntax support (instead of ANSI). PURPOSE
This module is used with Oracle < 9.0 due to lack of support for standard ANSI join syntax. SYNOPSIS
DBIx::Class should automagically detect Oracle and use this module with no work from you. DESCRIPTION
This class implements Oracle's WhereJoin support. Instead of: SELECT x FROM y JOIN z ON y.id = z.id It will write: SELECT x FROM y, z WHERE y.id = z.id It should properly support left joins, and right joins. Full outer joins are not possible due to the fact that Oracle requires the entire query be written to union the results of a left and right join, and by the time this module is called to create the where query and table definition part of the SQL query, it's already too late. METHODS
See DBIx::Class::SQLMaker::OracleJoins for implementation details. BUGS
Does not support full outer joins. Probably lots more. SEE ALSO
