Translating a query to use Zend_Db_Select

由 怎甘沉沦 提交于 2020-01-12 03:49:05
问题 I'm having some problems translating this query to use ZF's Zend_Db_Select : SELECT b.id, b.title, b.description FROM memberships AS m JOIN blogs AS b ON b.id = m.blog_id WHERE m.user_id = ? ORDER BY m.created LIMIT 0, 30 (this query works and returns results) Memberships is a link table between blogs and users . It's a simple | id | blog_id | user_id | affair. Here's what I have so far: // $table = Zend_Db_Table instance, $id = a user id $select = $table->select() ->from(array('m' =>

setIntegrityCheck in Zend Selects with joins

由 落爺英雄遲暮 提交于 2020-01-01 02:33:05
问题 I was looking at some questions that ask how to do joins in Zend Framework queries, but the answer is always something like "just do setIntegrityCheck(FALSE) ". My question is: why do I need to do this? It seems to me disabling "integrity checks" is not the proper way of making this work. In my particular case, I'm using a MySQL database with some InnoDB tables with foreign keys, so for example: CREATE TABLE IF NOT EXISTS `tableA` ( `id` CHAR(6), `name` VARCHAR(255), PRIMARY KEY (`id`) )

Zend 2: SQLSRV: $prepareParams is not being set

由 老子叫甜甜 提交于 2019-12-20 04:26:14
问题 Can somebody explain me where the ->setPrepareParams(array $prepareParams) is called in Zend\Db\Adapter\Driver\Sqlsrv\Statement.php? Specifically, when I used this: $this->tableGateway->select(array("Personalnummer = $personalnumber")); It worked. But when I used this: $this->tableGateway->select(array("Personalnummer" => $personalnumber)); It did not work. I tried to debug this and found that the params were not being set with my second method. 回答1: It is a public method so it is up to the

Issue with quoting of IS, NULL, NOT, !, and other reserved strings in ON conditions of JOIN clauses in Zend Framework 2

问题 I have an SQL statement, that selets sport classes/courses ( courses ) with their trainers ( trainers ) over an association table ( courses_trainers ). Since some courses have multiple trainers, I use the GROUP_CONCAT(...) function to get the trainer names into one field. Some trainers rows are empty or NULL , so I add a trainers.name IS NOT NULL and a trainers.name != "" condition to the ON clause of the trainers JOIN : SQL statement SELECT courses.id AS id, GROUP_CONCAT(DISTINCT trainers

Zend Framework: Re-use WHERE clause returned from Zend_Db_Select::getPart()

由 人走茶凉 提交于 2019-12-10 19:59:57
问题 I have a SELECT object which contains a WHERE. I can return the WHERE using getPart(Zend_Db_Select::WHERE) , this returns something like this: array 0 => string "(clienttype = 'agent')" 1 => string "AND (nextpayment < (NOW() - INTERVAL 1 DAY))" This array seems pretty useless as I cannot do this with it $client->update(array("paymentstatus" => "lapsed"), $where); Or even put it into another SELECT object. Is there a way of getting a more useful representation of the WHERE statement from the
