( #3333=superdoc: print w/replies, xml ) Need Help??

As it looks as though you are using Oracle, you should go and get the latest release candidate (1.24 RC4) which can be found here as it contains fixes for retrieving multiple rows at a time. Also see Bug #46763 for DBD-Oracle: RowCacheSize is being ignored slowing and Bug #46998 for DBD-Oracle: Why is RowCacheSize limited to 128.

    [Corion]: Meh. I have a very simple mechanism to scrape+track prices, and even to send me mail if something changes (via cron), but SQLite doesn't support window functions, so my simple SQL to determine a price change won't work :-( Maybe I should store the DB ...
    [Corion]: ... in Pg, but that would mean that I'd have to deal with credentials and stuff :)
    [Corion]: In fact, the whole thing is just four simple programs, one App::scrape, another being DBIx::RunSQL, and one some glue to convert a JSON object into an SQL INSERT statement (+DBI connect/execute), so it would be an incredibly simple solution...
    [Corion]: ... but that simplicity falls down due to SQLite letting me down and me being too lazy to move to a real DB. Maybe DBD::CSV can handle window functions...
    [hippo]: Pg has the "trust" mechanism if you don't fancy using credentials for a trivial db.
    [Corion]: hippo: Oooh, that sounds quite nice - let me read the documentation on that :)
    [hippo]: https://www. postgresql.org/ docs/current/ static/auth- methods.html#AUTH- TRUST
    [erix]: or compile & run an instance as yourself (not user 'postgres')
