Controls whether table and column descriptions are returned via the platform metadata APIs and sys_tables / sys_views / sys_tablecolumns.

解説

By default table and column descriptions are not shown, since the Oracle OCI requires an extra join in meta-query beyond what is usually required to read system views describing the object comments.

Enabling this option will show table and column descriptions. This can slow down metadata operations on large datasets.
