zend-db-table

There's this constant war going on in my thoughts when I work on a Zend Framework project -- good application design mandates that the number of database queries be minimized. Each query is expensive in terms of both latency and RDBMS calculation time. And Zend_Db_Table encourages you to make lots of queries -- there's no built in way to JOIN with other Zend_Db_Tables, for example. And there's no way to extract the name of the underlying table given an instance of Zend_Db_Table, which makes writing Zend_Db_Select queries in terms of Zend_Db_Table difficult. In a sense, Zend_Db_Table encourages

I am new to zend. I have been asked to redevelop a website that was once written in plain PHP and put it into the zend framework. I am having a lot of trouble with database relationships, I cant seem to get my head round defining and querying relationships. I would like to find a Category. From that Category I would like to be able to find all the CategoryInfo associated with it, and be able to query/sort/limit that dataset. Here are my models. Categorys.php <?php class Default_Model_Categorys extends Zend_Db_Table_Abstract { protected $_name = 'Categorys'; protected $_primary = 'id';

Using Zend Framework, I've created a Model to insert a record into a database. My question is, after $this->insert($data) how can I switch the active table so that I can insert a record into another table? Here's my code so far: class Model_DbTable_Foo extends Zend_Db_Table_Abstract { protected $_name = 'foo'; public function addFoo($params) { $data = array( 'foo' => $params['foo'], ); $this->insert($data); $foo_id = $this->getAdapter()->lastInsertId(); $data2 = array( 'bar' => $params['bar'] ); // I need to change the Db Table name here. $this->insert($data2); $bar_id = $this->getAdapter()-

I am using this to retrieve the database connection atm. $db = Zend_Db_Table::getDefaultAdapter(); I do set this up in my config like this: resources.db.adapter = pdo_mysql resources.db.isDefaultTableAdapter = true resources.db.params.host = localhost resources.db.params.username = root resources.db.params.password = password resources.db.params.dbname = db resources.db.params.profiler.enabled = true resources.db.params.profiler.class = Zend_Db_Profiler I would like to output everything to a sql.log for example. Is this possible to apply on the default adapter? for example through the settings

I am creating a web site using php, mysql and zend framework. When I try to run any sql query, page generation jumps to around 0.5 seconds. That's too high. If i turn of sql, page generation is 0.001. The amount of queries I run, doesn't really affect the page generation time (1-10 queries tested). Stays at 0.5 seconds I can't figure out, what I am doing wrong. I connect to sql in bootstrap: protected function _initDatabase () { try { $config = new Zend_Config_Ini( APPLICATION_PATH . '/configs/application.ini', APPLICATION_ENV ); $db = Zend_Db::factory( $config -> database); Zend_DB_Table

In terms of project scale, doctrine vs zend-db-table speed and performance, when should I use doctrine inside Zend project, and when zend-db-table? Any ORM framework gives you benefit for development productivity, not runtime efficiency. Doctrine is no different from Zend_Db_Table in this regard. If you are choosing between Doctrine and Zend_Db_Table, choose based on the features that make it easier or faster to write the code. No ORM framework can automatically make database queries faster in the general case. If you need high-performance database queries, you should learn to code SQL queries

Extended Question: Why should I use data mapper / Db_Table_Row, where as DbTable is capable of handling most of the basic tasks for data manipulation. I am currently learning ZF v1.11 For Database manipulation, I created DbTable for each tables. For example, "users" table is represented by Application_Model_DbTable_Users with no additional codes in there. When manipulating data, I can use: <?php $uTable = new Application_Model_DbTable_Users(); $newUid = $uTable->insert(array('name'=>'Old Name', 'email'=>'')); $user = $uTable->find($newUid)->current(); // Then I can use $user which is instance

i am using Join query in zend.. like $select = $table->select() ->from(array('e' => 'EducationHistory'), array('status_DataDictionary_id')) ->join(array('r' => 'ReportOrder'), 'e.id = r.EducationHistory_id', array('reportOrderStatusId' => 'r.status_DataDictionary_id')) ->where('r.orderBy_Organization_id = ?', 4) ->where('r.orderBy_Person_id = ?', 1) ->group('e.enrollno'); and to do that i take help from http://framework.zend.com/manual/en/zend.db.select.html but when i try to run that query an error occurs which say me that Select query cannot join with another could any one help me.? Thanks
