Thank you for all those attended my sessions during Collaborate 2010. Two of the sessions I presented were not mine; but that of Riyaj Shamsuddin.

For questions on those sessions, please reach out to Riyaj directly.

ops$tkyte%ORA10GR2> insert into t values ( 1 );
1 row created.
and you update a row in that table:
ops$tkyte%ORA10GR2> update t set x = x+1;
1 row updated.
