> *DataNucleus(DN): (Tested both mysql and postgres)*
> Upgrading to 6.0.0-release causes an issue when executing the hive-schema
> file.
>
> {code:java}
> Error: Error while compiling statement: FAILED: Execution Error, return code
> 40000 from org.apache.hadoop.hive.ql.ddl.DDLTask.
> MetaException(message:JDOUserException: Table ""PARTITION_KEYS"" has been

> not found in the table. Please check your <primary-key> column specification.
> [2024-04-11T21:28:16.977Z] Root cause:
> org.datanucleus.exceptions.NucleusUserException: Table ""PARTITION_KEYS"" has
> been specified with a primary-key to include column ""TBL_ID"" but this
> column is not found in the table. Please check your <primary-key> column
> specification.) (state=08S01,code=40000) {code}

>
> *Root Cause:* enclosing the primary key column name with quotes causes
> comparison problem and gives us that there is no column found even though it
> is present.
> *Commit which introduced the issue:*

> case values supported by DN are * uppercase

> "`PARTITION_KEYS`" has been specified with a primary-key to include column
> "`TBL_ID`" but this column is not found in the table. Please check your
> <primary-key> column specification.

> present (show databases has sys in it).

> *workaround solutions:* # Patched datanucleus-rdbms jar with modifying the
> required file.
> *Permanent solution:*
> Make the fix in datanucleus-rdbms repo. Requires a mini scale reproduction of
> this issue in a code to raise an issue in DN.
