[SPARK-13976][SQL] do not remove sub-queries added by user when generate SQL ## What changes were proposed in this pull request? We haven't figured out the corrected logical to add sub-queries yet, so we should not clear all sub-queries before generate SQL. This PR changed the logic to only remove sub-queries above table relation. TODO: for long term, we should find a way to add sub-queries correctly, so that arbitrary logical plans can be converted to SQL string. ## How was this patch tested? `LogicalPlanToSQLSuite` You can merge this pull request into a Git repository by running: $ git pull https://github.com/cloud-fan/spark bug-fix Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/11786.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #11786 ---- commit ee5a43739b895708c054558c62263a6a59aa4b1e Author: Wenchen Fan <wenc...@databricks.com> Date: 2016-03-17T16:08:16Z do not remove sub-queries added by user when generate SQL ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
