(Oracle only) This is where you
specify whether the records retrieved by the selected Query object
should be referenced by means of their ROWIDs. If not, for example
because the table is an RDBMS view, you can set this property to
No.
Also, you must set this
property to No if you have changed the underlying query to
something like:
SELECT DISTINCT <non-key column>
FROM <mytable>
Otherwise the DISTINCT clause
will apply to the (implicitly used) ROWID instead of the non-key
column. The "same" data might then appear to be displayed more than
once.
