I would like to implement generic code to access OLD and NEW context variables within a trigger.

So
A) can I derive the Tablename within a trigger

B) Can I access the context variables using an array or some other variable
e.g. I can derive the column names if I know the table name
Knowing the column name can I access its value e.g. ColName1.OLD

Ultimately I want to pass the Tablename and Primary key values from a Trigger to a Stored procedure

Peter
