How many rows will be affected by ogg replicat in update/delete when KEYCOLS is in use? (Doc ID 1907881.1)

Oracle GoldenGate - Version and later
Information in this document applies to any platform.


We know that when PK/UI is in use, when replicat replicates update/delete, it will base on the key column values.

When there is no PK/UI, the update/delete will base on all the column, and 'and rownum=1' is added to make sure it affects only one row.

Now the question is if we use keycols in above 2 scenarios, will it affect if  'and rownum=1' will be added or not?
