Get the last entry from a database table

Let's say you got a table(Users) with 3 fields(ID, FirstName and LastName), you need to get the last ID entry in that table, in this case you can use this nice SQL function

SELECT MAX("ID") FROM "Users";

you can do same for any other field, let's say FirstName

SELECT MAX("FirstName") FROM "Users";

MAX - is a SQL function which returns the last entry in the specified table.
