solution 1:
update table_name set
salary = isnull(salary,0) + 100
solution 2:
update table_name set
salary = case when
salary is null then 100
else salary + 100
end

If there exist a index on the table, and we then make a
view on that table (include the indexed column from base
table) than why do we require indexing on view?Doesnt it
create an overhead?
could you please reply for these question:
1.About Use Apply?
2.Avoid cursors - When we have a situation that we can not
avoid the use of cursor than what is the alternate solution?
is there anything we can use instead of cursor to perform
the desired task? which optiomize the peroformance too.
3.What is computed columns?
Thanks in advance.

I have a huge amount of data which is displayed in a
report. The data is viewed every day. Every day the data is
displayed in 30 secs but suddenly today it is giving an
timeout message today. Data has not been changed. The
situation is same as yesterday. What might be the reason???
Please Answer.
