如何在zend 2中查询以下内容
select * from states st where TRIM(LOWER(st.state_name))='noida'
任何帮助表示赞赏。谢谢
/* DB Adapter get and SQL object create */
$adapter = GlobalAdapterFeature::getStaticAdapter();
$sql = new \Zend\Db\Sql\Sql($adapter);
/* Select object create */
$select = new \Zend\Db\Sql\Select();
$select->from('states');
$select->where->addPredicate(
new \Zend\Db\Sql\Predicate\Expression(
'TRIM(LOWER(state_name)) = ?',
'noida'
)
);
/* Select object convert to string and execute */
$queryString = $sql->getSqlStringForSqlObject($select);
$result = $adapter->query($queryString, Adapter::QUERY_MODE_EXECUTE);
