Mysql query in zend framework 2 - php

Question

$dbAdapter = $this->adapter;
$sql = new Sql($dbAdapter);
$sQuery = $sql->select()
->from(array('c' => 'company'), array('name', 'jobtitle', 'experience', 'skill'))
->joinInner(array('j' => 'jobpost'), 'c.cid = j.cid');
In this query, I am getting error:
PHP Fatal error: Call to undefined method Zend\Db\Sql\Select::joinInner().
And classes i used in this :
use Zend\Db\Adapter\Adapter;
use Zend\Db\Sql\Sql;
use Zend\Db\TableGateway\AbstractTableGateway;

Answer 1

You should remove joinInner and add join
$dbAdapter = $this->adapter;
$sql = new Sql($dbAdapter);
$sQuery = $sql->select()
->from(array('c' => 'company'), array('name', 'jobtitle', 'experience', 'skill'))
->join(array('j' => 'jobpost'), 'c.cid = j.cid');
By default it will do an Inner join. If you want to specify the join then the documentation example from zend
should make it clear.
$select->join(
'foo' // table name,
'id = bar.id', // expression to join on (will be quoted by platform object before insertion),
array('bar', 'baz'), // (optional) list of columns, same requiremetns as columns() above
$select::JOIN_OUTER // (optional), one of inner, outer, left, right also represtned by constants in the API
);
You will also need the two lines Hary added in his answer,
$statement = $sql->prepareStatementForSqlObject($sQuery);
$result = $statement->execute();
and the you can return your result
return $result->toArray();

Answer 2

use Zend\Db\Sql\Sql;
use Zend\Db\Adapter\Adapter;
$dbAdapterConfig = array(
'driver' => 'Mysqli',
'database' => 'dbname',
'username' => 'dbusername',
'password' => 'dbuserpassword'
);
$dbAdapter = new Adapter($dbAdapterConfig);
$sql = new Sql($dbAdapter);
$sQuery = $sql->select();
$sQuery->from(array('c' => 'company'), array('name', 'jobtitle', 'experience', 'skill'));
$sQuery->joinInner(array('j' => 'jobpost'), 'c.cid = j.cid');
$statement = $sql->prepareStatementForSqlObject($sQuery);
$result = $statement->execute();
