To remove duplicate rows from a data table is like cleaning up a list so that each item is unique. Here’s a simple way to understand it:
- Look at Your List:
- Imagine you have a list of items, like fruits.
- Find Duplicates:
- Check if there are any fruits that are listed more than once.
- Keep Only One:
- If you see a fruit more than once, just keep one of them. Remove the extra copies.
- Your List is Clean:
- Now, your list has only unique fruits. No duplicates!
In terms of a data table, it’s like making sure each row has different information. You don’t want the same information repeated, so you clean it up by keeping only one of each.
