How can I alias sql select columns in laravel query builder?-CodePudding

I have a query like this where I am not sure how to alias the select columns for each table. Could you help me with that?

$columns = array_merge(json_decode($data->columns), json_decode($data->columns2));

$result = DB::table($data->type)
                    ->select($columns)
                    ->join('tabs', 'data.id', '=', 'tabs.app_bundles_id')
                    ->get();

To answer your question, you add AS newColumnName as you would in SQL:

->select(['name AS title', 'email AS emailAddress']).

Additionally, you really really don't want to pass table names and column names unsanitized to your query like this. They are NOT sanitized by Laravel and are a potential vulnerability. More info can be found in the callout box at https://laravel.com/docs/8.x/queries#where-clauses

From the comments I concluded you want to select the columns from $data->columns and alias them like they're in $data->columns2. I don't know the data structure for neither, but I think you mean something like this:

$select = array_map(
    function($column, $alias) {
        return "{$column} AS {$alias}";
    }, 
    $data->columns,
    $data->columns2
);

var_dump($select);
