Question

我正在使用Laravel 5.2。我想用两个部分写一个查询：

$getData =  DB::table($table)
            ->where($where);
$getData->first();

return $getData;

但它不适合我。它没有向我提供正确的数据。

它给出了：

Array ( [aggregate] => [columns] => [distinct] => [from] => countries [joins] => [wheres] => Array ( [0] => Array ( [type] => Nested [query] => Array ( [aggregate] => [columns] => [distinct] => [from] => countries [joins] => [wheres] => Array ( [0] => Array ( [type] => Basic [column] => country_name [operator] => = [value] => India [boolean] => and ) ) [groups] => [havings] => [orders] => [limit] => [offset] => [unions] => [unionLimit] => [unionOffset] => [unionOrders] => [lock] => ) [boolean] => and ) ) [groups] => [havings] => [orders] => [limit] => 1 [offset] => [unions] => [unionLimit] => [unionOffset] => [unionOrders] => [lock] => )

但是当我这样打电话时它能正常工作：

$getData =  DB::table($table)
                ->where($where)->first();
return $getData;

我们不能在laravel中分两部分调用查询。

Answer 1

您必须从$getData->first();

取回返回的数据

$getData =  DB::table($table)
              ->where($where);
$getData = $getData->first(); // <----

return $getData;

如何分两部分编写Laravel Query
