Remove multiple columns from writing into a file
i’m looking for an approach where i can remove multiple columns from writing into a file. The catch here is I don’t want to hardcode the column names (at source column) and passing null (in target column). I want to identify the unwanted column based on the prefix (say Join_) and remove all those columns from writing into a file. Say Im getting column A B C D Join_A Join_B I don’t want to write Join_A and Join_B in file. I can’t hardcode the column names because I’m not sure how many such columns with that prefix i will get. Any pointers would be appreciated. tia2.2KViews0likes1Comment
