Patch Set 20: > There is still one thing that is not clear to me. Why is it allowed > to do an ALTER TABLE with an empty SORT BY clause but not a CREATE > TABLE? The easiest way to specify an empty list of sort by columns during CREATE TABLE is to omit the SORT BY clause altogether. To keep things simple I did not add additional support for an empty SORT BY () clause. For ALTER TABLE there needs to be a way to specify an empty list of columns, but since SORT BY is used to identify the command, the most simple form seemed to be an empty column list(). Do you think we should allow CREATE TABLE SORT BY() in addition to specify an empty set of column? -- To view, visit http://gerrit.cloudera.org:8080/6495 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: I08834f38a941786ab45a4381c2732d929a934f75 Gerrit-PatchSet: 20 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Lars Volker <l...@cloudera.com> Gerrit-Reviewer: Alex Behm <alex.b...@cloudera.com> Gerrit-Reviewer: Dimitris Tsirogiannis <dtsirogian...@cloudera.com> Gerrit-Reviewer: Lars Volker <l...@cloudera.com> Gerrit-Reviewer: Marcel Kornacker <mar...@cloudera.com> Gerrit-Reviewer: Thomas Tauber-Marshall <tmarsh...@cloudera.com> Gerrit-HasComments: No
