I do not know how to use MERGE and did not find much information on it. But I looked into modifying it and once again, it compiles in this case but when I run it using the debugger, no code is inserted into the table at all. And it exits with a row number = 0 at line
RETURN L_rowcount;
Is there something about running procedures on Oracle that I seem to be missing here please??? I went ahead and included information on my table as well.
