  • Doctrine_Query update with float value

    - by YS-PRO
    I need to increment User's balance, so I do: Doctrine_Query::create()->from('User')->update('balance', 'balance + 0.15')->execute(); And I got an error "Unknown component alias 0". I think its because of 0.15 So how can I update (using DQL) balance without additional SELECT queries to User's table to fetch his balance, calculate new balance and do query like Doctrine_Query::create()->from('User')->update('balance', '?', $new_balance)->execute();

    PDO apparently has no means to count the number of rows returned from a select query (mysqli has the num_rows variable). Is there a way to do this, short of using count($results->fetchAll()) ?

  • Cleansing string / input in Coldfusion 9

    - by Jakub
    I have been working with Coldfusion 9 lately (background in PHP primarily) and I am scratching my head trying to figure out how to 'clean/sanitize' input / string that is user submitted. I want to make it HTMLSAFE, eliminate any javascript, or SQL query injection, the usual. I am hoping I've overlooked some kind of function that already comes with CF9. Can someone point me in the proper direction?

  • Where can I find an ADOExpress tutorial?

    - by mawg
    I'm using Delphi 7, totally new to database programming, and need ODBC. I am told that ADOExpress is a good way to go, and that seems fair enough as it comes with Delphi 7. I need to programatically create, populate, modify and query a database (currently MySql, but that might change, hence ODBC). Can anyone recommend a good tutorial? Thanks.

  • How to round down a DateTime value

    - by timpone
    I have a Location that can have Events. I want to have an upcoming_events method but want it to round down such that if someone looks at 10pm at night, it will show todays events. I have this: def upcoming_events d=Time.new d.strftime("%m-%d-%Y") l=Event.where('location_id=? and start_datetime>?',self.id, d) end I gets converted down correctly but in d.strftime but the query is: SELECT `events`.* FROM `events` WHERE (location_id=301 and start_datetime>'2012-06-20 02:49:23') Any idea how to just get it to do '2012-06-20'?

  • Selecting all but one field?

    - by gsquare567
    instead of SELECT * FROM mytable, i would like to select all fields EXCEPT one (namely, the 'serialized' field, which stores a serialized object). this is because i think that losing that field will speed up my query by a lot. however, i have so many fields and am quite the lazy guy. is there a way to say... `SELECT ALL_ROWS_EXCEPT(serialized) FROM mytable` ? thanks!
