Background
It was possible for virtual tables to have missing table comments in Exasol metadata views when the virtual schema adapter defined a table comment. This issue occurred when the adapter provided a comment for a virtual table. In this situation, the comment was not exposed through EXA_DBA_TABLES.
As a result, queries against Exasol metadata views could return empty table comments for virtual tables, even when a comment was defined by the virtual schema adapter.
Improvement
Table comments provided by virtual schema adapters are now correctly exposed through EXA_DBA_TABLES. Queries against Exasol metadata views now return the table comments defined by the virtual schema adapter.
