Trying to get all column names in a table

Question

I found this answer which says to do like this:

$columns = Schema::getColumnListing('users');

But it doesnt say what to use, but I suppose it should be:

use Illuminate\Database\Schema\Builder as Schema;

But when I try it it doesnt work:

$columns = Schema::getColumnListing("users");

I get error:

Non-static method Illuminate\Database\Schema\Builder::getColumnListing() should not be called statically, assuming $this from incompatible context

Answer 1

You can do:

$columns = DB::getSchemaBuilder()->getColumnListing('users');

And use DB; to import the needed dependencies.

Answer 2

为了解决最初的问题，它之所以不起作用，是因为你应该只使用它：

use Schema;

而不是：

use Illuminate\Database\Schema\Builder as Schema;
