Script to fetch all fields from a table which is not inherited

HI All,

I have a table which is extended from CMDB CI. There are also many custom fields created in the child table.

Does anyone have a way to fetch the list all the custom fields from the child table via script?. it should only give results of non extended fields belonging to the child. It a huge table so I cannot check fields one by one.

I have done this before but somehow unable to get hold of the script again.

Thanks
