Answer / praveen n h
SQL server will execute the query in following way...
Select All top 5 rows which are created in the table from
the time it is created.
reason: newid is the key given to each row regardless of
the values that goes into the row of the table.
For example.
if you have created a table temp
and inserted 10 rows, Only fives rows which are created
first will be listed.
