How to get raw sql query in yii or yii2 framework

how to get sql query from facade DB::table in laravel 5

Normally we fetch the data as below

$dataresult = DB::table(‘sometable’)
->select(‘sometable.column1’, ‘sometable.column2’, ‘sometable.column3’, ‘sometable.column4’, ‘sometable.column5’)
->get();

Now if we want to get the actaul query from $dataresult using $dataresult->toSql(); // it will not work

The solution for this is first prepare the query without the get() method and then call the toSql() method as below.

$dataQuery = DB::table(‘sometable’)
->select(‘sometable.column1’, ‘sometable.column2’, ‘sometable.column3’, ‘sometable.column4’, ‘sometable.column5’);

$dataQuery->toSql(); // this will give you the actual query

After that you can fetch the result as below.
$dataresult = $dataQuery->get();

Self join criteria in symfony

For Example :
SELECT tbl1.id FROM tbl1 a LEFT JOIN tbl1 b ON a.somecolumnname = b.somecolumn ORDER BY a.somecolumn DESC

The criteria would be as follow

$c=new Criteria();
$c->addAlias(‘a’, ‘tbl1’);
$c->addAlias(‘b’, ‘tbl1’);
$c->addSelectColumn(‘b.id’);
$c->addSelectColumn(‘a.tbl1_id’);
$c->addDescendingOrderByColumn(‘a.somecolumn’);
$c->addJoin(‘a.somecolumnname’,’b.somecolumn’,Criteria::LEFT_JOIN); // Specify your criteria LEFT, RIGHT or INNER
$rs = tbl1Peer::doSelect($c);

select multiple column from multiple table in cakePHP

$markers = $this->Post->find(‘all’, array( ‘joins’ => array(
array(
‘table’ => ‘cp_user’,
‘alias’ => ‘users’,
‘type’ => ‘left’,
‘foreignKey’ => false,
‘conditions’=> array(‘Post.postauthor = users.id’)
)
),
‘conditions’=>’Post.poststatus = 1’,
‘fields’=>array(‘Post.postid’,
‘Post.postdate’,
‘Post.posttitle’,
‘Post.postmessage’,
‘Post.poststatus’,
‘Post.commentstatus’,
‘Post.commenttotal’,
‘Users.id’,
‘Users.firstname’
)
)
);

$this->set(‘cp_post’,$markers);
