Detailed Description

Class SQLQuery This class is to MANAGE a query that is maybe more complex than a standard sql-query. You can easily add filters, joins and additional select-parts.

$query = SQLQuery::table("auth_user_md5") ->join("seminar_user", "seminar_user.user_id = auth_user_md5.user_id") ->join("seminar_inst", "seminar_inst.seminar_id = seminar_user.Seminar_id") ->where("seminar_inst.institut_id = :institut_id",array('institut_id' => $inst->getId())); if (Request::get("status") { $query->where("auth_user_md5.status = :status", array('status' => Request::get("status")); } if ($query->count() <= 500) { $user_data = $query->fetchAll(); } else { PageLayout::postInfo(_("Geben Sie mehr Filter ein.")); }

Parameters

$sorm_class_or_column

: column name, a class of SimpleORMap or null for associative array.

Returns

array of arrays or array of objects or array of values.

getPrimaryKey ( )
