Oracle Procedures to delete the parent child table rows with integrity constraints.

With some very hard work and innovative thinking we came up with the procedures (can be easily clubbed into package) to delete the parent child relationship row with any number of levels. Below code would find the child row of the parent row being deleted and delete it first , if the child row has its own child then that childs children are fetched and deleted so its basically a recursive algorithm There are not many situations where you would want to use this. We had a customer mstr record to be deleted which had 20 levels of child records held tight by (ORA-02292: integrity constraint   violated - child record found ) with their parent child constraints. Since this only was a delete for 1 Master record we went ahead and used this script. If you have more than 20 levels Wise course would be to disable constraints and really think why you want to delete such master record. Note of caution : BE CAREFUL using this on production environment. The procedures create the insert ...

It was fairly small 10 liner code which was astonishing. Curiously I never saw the function used anywhere. The function clob2file is from package dbms_xslprocessor. This one is available in oracle 11g so if you ever found yourself yearning to dump a clob object to file you should try using this. There was just a little problem I wante...
