In Exasol, CLOB is an alias for VARCHAR. When querying a foreign table with a CLOB column defined as
ObjectValue clob OPTIONS (NATIVE_TYPE 'varchar(4000)', NAMEINSOURCE 'objectvalue'))
,
an exception is logged in the server output for each row.
The query itself finishes successfully and the returned results are correct.
