Laravel - 使用单个查询组合多个查询来更新两个表的数据

Question

In one of my Laravel project, I have to update two table's data within a same scope of a function. At first query, I am trying to update data of a table using following query -

        DB::table('parameters')
        ->where($where)
        ->update($data);

In second and third query I am adding and subtracting two column's of another table -

DB::table('categories')
            ->where(['id' => $data['category_id']])
            ->increment('parameters');

DB::table('categories')
            ->where(['id' => $previous_category_id])
            ->decrement('parameters');

Everything is working fine. But, now I want to do all these operations within one query execution.

As far as I understand this there is no way to do this with one query.

What you are basically doing with the DB:table facade is runnig a MySQL UPDATE statement like: UPDATE <table_name> SET <field_name>=<value> WHERE condition

As you can see an UPDATE query is pointed to exactly one table, not more. So for updating multiple tables you need to run multiple UPDATE queries.
