Hi,
I couldnt check the whole proc, I was in a hurry. But I can tell u the reason why this error comes. It comes whe you try to insert a value in a variable which is greater than its size. E.g if variable x is varchar2(3), then this sentence will give the PL/SQL numeric error :
x := 'Amit';

And the other reason is when u try to enter alphanumeric character into a number variable.

Thanks
Amit

You'll kick yourself! -- You've defined c_test as VARCHAR2(50), but the fixed-string part of the SQL statement is 47 characters before you add the owner and table name. If you redefine c_test as, say, VARCHAR2(500) it should work properly.

The result of coding on a friday, I guess.
