Attachment: HIVE-23128.1.patch
> SHOW CREATE TABLE Creates Incorrect Syntax When Database Specified
> ------------------------------------------------------------------
>
> Key: HIVE-23128
> URL: https://issues.apache.org/jira/browse/HIVE-23128
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.4.0, 3.1.2
> Reporter: David Mollitor
> Assignee: David Mollitor
> Priority: Major
> Attachments: HIVE-23128.1.patch
>
>
> {code:sql}
> show create table `sample_07`;
> show create table `default`.`sample_07`;
> show create table `default.sample_07`;
> {code}
> {code:none|title=Results}
> CREATE TABLE `sample_07`(...)
> CREATE TABLE `default.sample_07`(...)
> CREATE TABLE `default.sample_07`(...);
> {code}
> All three queries complete in Hive 2.x (not sure about 3.x) but the results
> are consistent in both versions. The first result is correct because it does
> not include the database name, however, the subsequent two results are
> invalid: each field must be quoted individually.
> {quote}
> If any components of a multiple-part name require quoting, quote them
> individually rather than quoting the name as a whole. For example, write
> `my-table`.`my-column`, not `my-table.my-column`.
