How to run raw SQL Query with Zend Framework 2

Question

Is there a way to execute a SQL String as a query in Zend Framework 2?

I have a string like that:

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


        

Answer 1

Just pass the sql string to your db adapter like this:

$resultSet = $adapter->query($sql, \Zend\Db\Adapter\Adapter::QUERY_MODE_EXECUTE);

And if you want to pass parameters:

$sql = "SELECT * FROM testTable WHERE myColumn = ?";
$resultSet = $adapter->query($sql, array(5));

EDIT: Please note that the query method does not always returns a resultset. When its a resultset producing query(SELECT) it returns a \Zend\Db\ResultSet\ResultSet otherwise(INSERT, UPDATE, DELETE, ...) it will return a \Zend\Db\Adapter\Driver\ResultInterface.

And when you leave the second Parameter empty you will get a \Zend\Db\Adapter\Driver\StatementInterface which you can execute.
