I am not very much efficient in SQL Query so wanted to know how to fetch last N records or rows from a table using query in SQL Server.
Like, we can do using TOP keyword in SQL Server to fetch first 10 results as below
This is more of a big data question(GFS related). I'm not getting how checkpointing help? Can you share 1 example(which could be DBMS example).
Say these are the operations on the database.
