This will show you the table for chained rows, not sure if it covers migrated or not, anyone else?

 select owner, table_name, chain_cnt from dba_tables where chain_cnt > 0;


You can have it: Fast, Right or Cheap, pick 2 of the 3. Fast + Right is Expensive
Fast + Cheap will be incorrect.
Right + Cheap will take a while.

Row Migration/Rowchaining

In my database when I run the following query against v$sysstat, I find huge number of migrated/chained rows.

SQL> SELECT name, value

       FROM v$sysstat
       WHERE name = 'table fetch continued row';

NAME                               VALUE

---------------------------------- --------
table fetch continued row 2327441

How do I find to which table these migrated/chained rows belong?

Please help.
