if you're running RC2, a lot of the model stuff has been reformed and the former items which only performed queries on 1 row handle everything now |

is it possible to get some kind of SQL out from a shell task? |

I thinked that del was only for one item |
| # |
Aug 9th 2008, 05:54 |
Howard`` |
yw :D |
| # |
Aug 9th 2008, 05:54 |
skua |
thank a lot ! |
| # |
Aug 9th 2008, 05:54 |
skua |
ah yeah that work's ! |
| # |
Aug 9th 2008, 05:54 |
Howard`` |
should delete those ids |
| # |
Aug 9th 2008, 05:54 |
Howard`` |
then just $this->Model->del |
| # |
Aug 9th 2008, 05:54 |
Howard`` |
well you can just set the model ID in cake with $this->Model->id = $ids |
| # |
Aug 9th 2008, 05:53 |
skua |
you mean Model->del($ids) ? |
| # |
Aug 9th 2008, 05:53 |
Howard`` |
you could just use $this->Model->del actually i think |
| # |
Aug 9th 2008, 05:53 |
Howard`` |
I've never done it with an array but i'd imagine it would work the same |
| # |
Aug 9th 2008, 05:53 |
Howard`` |
I think you can just save a headache and write $this->Model->id = $ids; then $this->Model->deleteAll |
| # |
Aug 9th 2008, 05:52 |
skua |
that should work not ? |
| # |
Aug 9th 2008, 05:51 |
skua |
$this->Model->deleteAll(array('id' => $ids) ); |
| # |
Aug 9th 2008, 05:51 |
skua |
$ids = array('2','3','4','5'); |

ok take care, AD7six |

Howard`` |
alright then |
| # |
Aug 9th 2008, 05:49 |
AD7six |
or rather make it work then make it work better.678 |

Howard``: if not don't over think - forget sharding, forget everything. make it owrk and then just add indexes - which make finding info (find all messages to this user) faster |
| # |
Aug 9th 2008, 05:48 |
Howard`` |
the idea can work i just need to figure out how to put everything together |
| # |
Aug 9th 2008, 05:48 |
Howard`` |
no it's really just me and a friend who helps me run servers |
| # |

Howard``: got a dba on the team? |
| # |
Aug 9th 2008, 05:47 |
Howard`` |
sorry i'm just a little bit over my head, trying to make sense of it all, databases aren't my strong suit |
| # |
Aug 9th 2008, 05:47 |
AD7six |
also I pointed out indexes and you asked about primary keys - indexes aren't primary keys |
| # |
Aug 9th 2008, 05:47 |
AD7six |
Howard``: I'm giving you examples and you're asking about app logic |
| # |
Aug 9th 2008, 05:46 |
Howard`` |
would sync occur on a cron or immediately? |
| # |
Aug 9th 2008, 05:45 |
AD7six |
well it doesn't matter so long as it's unique and can/will never change (don't use a username). uuids are useful to share info across dbs. i.e. allowing slaves to accept registrations to later sync with the master (if there is one) and other slaves. |
| # |

Howard`` |
I noticed virtual worlds tend to do the uuid |
| # |
Aug 9th 2008, 05:44 |
Howard`` |
what would you use for indexes on large databases? an auto_increment field, a username, or a uuid? |
| # |
Aug 9th 2008, 05:43 |
AD7six |
and it depends what you're doing and how you set it up (indexes!) |
| # |
Aug 9th 2008, 05:43 |
Howard`` |
oh ok |
| # |
Aug 9th 2008, 05:43 |
AD7six |
Howard``: a million rows isn't a lot |
| # |
Aug 9th 2008, 05:42 |
Howard`` |
isn't there a performance gain if you have 10 databases of 100k rows rather than 1 database of 1 million rows? |
| # |
Aug 9th 2008, 05:42 |
AD7six |
premature optimization otherwise. |
| # |
Aug 9th 2008, 05:42 |
AD7six |
Howard``: indexes -> dedicated db server -> clusters -> sharding. |
| # |
Aug 9th 2008, 05:41 |
AD7six |
Howard``: that's imo pretty much pointless. |

initially, after the first week or month i plan on spanning across a minimum of two servers |
