[..] What You could do (which does not speedy the thing at all ;-) still improves a situation from a user point of view, assuming the application is under Your control) is to run this as a job (or even few jobs if You are able to divide a work between few processes) and provide in some table a status to read - user is able to get the control almost immediately, and do other things. And another thought (if You have partitioning option) is to partition by user which approves transactions - everything one needs would be to exchange partition into another name (possibly twice if You want to have it within another "more general" table) Regards Remigiusz -- Pole nakazi ---------------------------------------------------------------------- Remigiusz Sokolowski <remigiusz.sokolowski@xxxxxxxxxx> pos : DBA at DIiUSI addr : Nordea Bank Polska SA, Luzycka 6A Street, 81-537 Gdynia, Poland phone : +48 58 667 17 43 mobile: +48 602 42 42 77 Nordea Bank Polska S.A. z siedziba w Gdyni, ul.
