Laravel DB::table 已提交更新

Question

我有这个问题

DB::table('pro_orders_has_passengers')
    ->where('title_name','MR.')
    ->update([
        'title_name' => 'mr',
    ]);
DB::table('pro_orders_has_passengers')
    ->where('title_name','MRS.')
    ->update([
        'title_name' => 'mrs',
    ]);
DB::table('pro_orders_has_passengers')
    ->where('title_name','Miss')
    ->update([
        'title_name' => 'ms',
    ]);
DB::table('pro_orders_has_passengers')
    ->where('title_name','Girl')
    ->update([
        'title_name' => 'girl',
    ]);
DB::table('pro_orders_has_passengers')
    ->where('title_name','Boy')
    ->update([
        'title_name' => 'boy',
    ]);

我得到了正确的结果。但我希望在一个查询中得到这个结果。

像这样：

$titlename = ['MR.','MRS.','Miss','Girl','Boy'];

DB::table('pro_orders_has_passengers')
    ->where('title_name',$titlename)
    ->update([
        ........
    ]);

我该怎么做？

Answer 1

    $titlename = ['mr' => 'MR.','mrs' => 'MRS.','ms' => 'Miss','girl' => 'Girl', 'boy' => 'Boy'];

    $update_query = "UPDATE pro_orders_has_passengers SET title_name = CASE";
    foreach ($titlename  as $new_title => $title) {
       $update_query = $update_query . " WHEN title_name = '$title'  THEN  '$new_title'";
    }
    $update_query = $update_query . " END WHERE title_name IN ('".implode(array_values($titlename), '\',\'')."')";
    \DB::statement($update_query);

试试这个方法。它将帮助您进行批量更新。

最终输出将是

UPDATE pro_orders_has_passengers SET title_name = CASE WHEN title_name = 'MR.' THEN 'mr' WHEN title_name = 'MRS.' THEN 'mrs' WHEN title_name = 'Miss' THEN 'ms' WHEN title_name = 'Girl' THEN 'girl' WHEN title_name = 'Boy' THEN 'boy' WHERE END title_name IN ('MR.','MRS.','Miss','Girl','Boy')

Answer 2

我认为这样你可以实现你正在寻找的东西

$titlename = ['MR.','MRS.','Miss','Girl','Boy'];
for($i=0; $i < count($titlename);$i++) {
DB::table('pro_orders_has_passengers')
            ->where('title_name',$titlename[$i])
            ->update(['title_name' => strtolower(str_replace('.', '' , $titlename[$i]))]);
}

或者使用 foreach 循环，以提高代码的可读性：

$titlenames = ['MR.','MRS.','Miss','Girl','Boy'];
foreach($titlenames as $titlename) {
DB::table('pro_orders_has_passengers')
            ->where('title_name',$titlename)
            ->update(['title_name' => strtolower(str_replace('.', '' , $titlename))]);
}

                    //-------Others cases-----//
                    ELSE LASTNAME
                END 
      WHERE title_name IN ('Mr.', 'Mrs.', .....)
);

Answer 4

您可以更新它：

DB::table('table_1')
                ->join("table_2", "table_1.foreign_id", "=", "table_2.id")
                ->where("table_1.fied_test", "=", "a_condition")
                ->where("table_2.user_id", "=", auth()->id())
                ->update(["table_2.status_test" => "EN_COURS"]);
