>                 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
>            Priority: Major
>
> {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`.
