Drop few columns before inserting into Oracle table

I am reading data from csv file before inserting the data into Oracle table,I want to delete or omit unnecessary columns. How to achieve this?Thanks in advance

If you put a mapper Snap in between, you can put the source fields in the source column, if you put no target for those fields, it will drop them in the data flow. Use the pass-through option to get all other fields passed to the output without having to put them all in the table

My coulmn datatype is DATE.
The timestamp snaplogic fetching : 2019-03-20T13:03:45+00:00
