问题 I want to generate a unique 4-6 char long AlphaNumeric string to save in db with each record(user). The db field has a unique index, so trying to save a pre-existing string generates an error. Right now I am generating a random string and using try-catch, so when adding a new record if it throws an exception, I generate another random string and attempt to save again, and the code keep trying until it adds a record successfully. This whole solution not only looks heavy but also ugly, so I

问题 I have a normalized database that stores locations of files on the internet. A file may have multiple locations spread across different sites. I am storing the urls in two parts (Site.UrlStart, FileLocation.UrlEnd). The UrlEnd is the part unique to that file (for the site). Simplified Db structure: http://img231.imageshack.us/img231/9134/dblayout.jpg I am using Zend_Db as my ORM (If it is that), with classes for the tables inheriting from Zend_Db_Table_Abstract. The issue is that retrieving

问题 This used to work but after some modifications by the other programmers it just fails to work. I have this code on my Bootstrap: protected function _initDatabase () { $resource = $this->getPluginResource('multidb'); $resource->init(); Zend_Registry::set('gtap', $resource->getDb('gtap')); Zend_Registry::set('phpbb', $resource->getDb('phpbb')); } Upon loading, this error shows up: Fatal error: Call to a member function init() on a non-object in /var/www/gamebowl3/application/Bootstrap.php on

问题 I'm using the zend framework to write an app and I'm having lots of problems getting my relational database models to work. I've read the quickstart and the docs several times and I'm still not sure how to do this. I post a picture of the relationships between the different tables involved to avoid having to explain everything since English is not my first language and I tend not to make myself clear when I try to explain...well complex things. The tables press_releases, social_networking,

问题 I'm trying to fetch the last inserted row Id of a Sqlite DB in my PHP application. I'm using Zend Framework's PDO Sqlite adapter for database handling. the lastInsertId() method is supposed to give me the results, but it wouldn't. In PDO documentation in php.net I read that the lastInsertId() might not work the same on all databases. but wouldn't it work on sqlite at all? I tried overwriting the lastInsertId() method of the adapter by this: // Zend_Db_Adapter_Pdo_Sqlite public function

问题 I'm dealing with database containing of many tables, with many field prefixes (two first letters of every table), so when I have users table I cannot use "name" property ($user->name) but I can use: $user->us_name. I's there a way to simplify things and set automagic prefix for every field of a table ? 回答1: You'd have to extend Zend_Db_Table_Row to accomplish this. Fortunately, ZF includes a _transformColumn() method expressly for this purpose. But I'm getting ahead of myself. First, set up

问题 Zend Framework beginner here. I'm trying to fetch all the Xbox titles of a video game database. One table contains games. Another table contains game types (ie. Xbox, Xbox Live Arcade, ...). I normally use the following query to get the Xbox titles. How can I execute the same query using Zend_Db? Thanks, SELECT titleGame FROM Game WHERE idGameType IN ( SELECT idGameType FROM GameType WHERE nameGameType = 'Xbox') 回答1: That could be rewritten in Zend Framework a few ways. Here is the way I

问题 My Atlas class performs a recursive data exploration given a non-contiguous but sequential set of col1 values, read from MySQL table1 beginning with $startingVal . Limit $totalVal is a throttle for work units during any given session. On each recursion, Atlas will retrieve between zero and eight (0-8) rows from a different table.
