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;
joe

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.
Thanks,
Rao
