RAW SQL Query with Zend Framework

问题:

Is there a way to execute a SQL String as a query in Zend Framework?

I have a string like that:

$sql = "SELECT * FROM testTable WHERE myColumn = 5"

now I want to execute this string directly withput parsing it and creating a Zend_Db_Table_Select object from it "by hand". Or if thats possible create a Zend_Db_Table_Select object from this string, to execute that object.

How can I do that? I didn't find a solution for this in the Zend doc.

If you're creating a Zend_DB object at the start you can create a query using that. Have a look at this entry in the manual : http://framework.zend.com/manual/en/zend.db.statement.html

$stmt = $db->query(
            'SELECT * FROM bugs WHERE reported_by = ? AND bug_status = ?',
            array('goofy', 'FIXED')
        );

Or

$sql = 'SELECT * FROM bugs WHERE reported_by = ? AND bug_status = ?';
$stmt = new Zend_Db_Statement_Mysqli($db, $sql);

If you are using tableGateway, you can run your raw SQL query using this statement,

$this->tableGateway->getAdapter()->driver->getConnection()->execute($sql);

where $sql pertains to your raw query. This can be useful for queries that do not have native ZF2 counterpart like TRUNCATE / INSERT SELECT statements.

You can use the same query in Zend format as

$select = db->select()->from(array('t' => 'testTable'))
                     ->$where= $this->getAdapter()->quoteInto('myColumn = ?', $s);
$stmt = $select->query();
$result = $stmt->fetchAll();

Here is an example for ZF1:

$db =Zend_Db_Table_Abstract::getDefaultAdapter();
$sql =    "select * from user"
$stmt = $db->query($sql);
$users =  $stmt->fetchAll();
