From 6e599ee099ce9beeddfc938574225b943c144bd8 Mon Sep 17 00:00:00 2001 From: Ryuta Kamizono Date: Fri, 22 Feb 2019 06:14:33 +0900 Subject: Fix `pluck` and `select` with `from` if `from` has original table name This is caused by 0ee96d1. Since #18744, `select` columns doesn't be qualified by table name if using `from`. 0ee96d1 follows that for `pluck` as well. But people depends that `pluck` columns are qualified even if using `from`. So I've fixed that to be qualified if `from` has the original table name to keep the behavior as much as before.
