Follow an exercise in paging results.
- [Instructor] In the previous video…we looked at ordering and limiting results…in order to prepare ourselves to actually do paging.…And paging is a construct within JBC…and really all database operations,…whereby we limit the amount of data…we return from the database in a given slice.…That way if we only need to see the first page,…we only see that.…But if we do need to see the 10th page…then we can slice through that data.…It provides a much more efficient mechanism…by getting data to the customer,…as opposed to giving them all the data at once.…
So let's take a look in Postgres how to implement paging.…So what I want you to do is jump back in your IDE.…Now I do want to reiterate here,…this is how you can do paging in Postgres.…There is more than one way to do paging,…and there's more than one way to do it across database.…This works for Postgres and this is a pattern…that I've utilized many times over.…So I'm going to show you my pattern for paging,…and you can expand on it as you wish.…The idea and concepts, however, will still be the same.…
