Hi,
This question might be already on forum But I couldn't find anything regarding it.
My question is: How to debug table function.
For Example I have function in package
Function Get_States (P_Parameter_1 In Number , P_Parameter_2 In Number ) Return Collection_type Pipelined ;
And Inside the function I have some row piping algorithm lets say some calculations. When I try to debug it it gives me Error.

Please guide me how to debug such Function.
