Chained rows

Hello Friends,

By chance do you folks have any scripts to find out the chainded and the migrated rows in the table?

Also please clarify the difference between Chainded rows Vs. Migrated rows.

Thanks,

If a row grows too big to fit in it's current block because there are others rows in the block, it gets migrated to a block that has space.

If the row is too big to fit in any single block, it gets chained across multiple blocks.

The dba_tables column "chain_cnt" is the sum of both of these I believe.
