Hi, this is Abdul Halim, working as a Sr. Oracle DBA and PL/SQL developer in USA. I very much like to play with SQL, PL/SQL and scripting languages along with my DBA job. I got a recognition for PL/SQL. Please see here at 16th position(http://plsql-challenge.blogspot.com/2010/07/winners-of-first-plsql-challenge.html). I am maintaining this blog for helping myself while in work and sharing my knowledge with others. If you have any question please email me at firstname.lastname@example.org Thanks.
