Dynamic update of cursor records when table gets updated

Question

Hi,
I am having a table with 4 columns as mentioned below
For a particular prod the value greater less than 5 should be rounded to 5 and value greater than 5 should be rounded to 10. And the rounded quantity should be adjusted with in a product starting with orderby of rank with in a prod else leave it
Table1
Col1     prod     value1     rank
1     A     2     1          
2     A     6     2
3     A     5     3
4     B     6     1
5     B     3     2
6     B     7     3
7     C     4     1
8     C     2     2
9     C     1     3
10     C     7     4
Output
Col1     prod     value1     rank
1     A     5     1          
2     A     5     2
3     A     3     3
4     B     10     1
5     B     0     2
6     B     6     3
7     C     5     1
8     C     5     2
9     C     0     3
10     C     4     4
I have taken all the records in to a cursor. Once after rounding the request of 1st rank and adjusting the values of next rank is done. Trying to round the value for 2nd rank as done for 1st rank. Its not taking the recently updated value(i,e adjusted value in rounding of 1st rank).
This is becoz of using a cursor having a value which is of old value.
Is there any way to handle such scenario's where cursor records gets dynamically updated when a table record is updated.
Any help really appreciated.
Thanks in Advance

Answer 1

Hi,
Below is the scenario. Which I am looking for.
ITEM_ID(A)
ITEM_ID Value Date
A          3     D1     
A          5     D2
A          3     D3     
A          5     D4
A          3     D5     
A          5     D6
Rounding for Item A has to be done for the rows less then D2 and rounding value is
x and value adjustment to be done from very next row.
--For record D1 rounding to be done and value adjustment is to be done from D2 to till the end untill the adjustment value is 0.
--For record D2 (updated value has to be taken from rounding which updated in D1 row rounding) and the adjustment has to be done from very next row D3 to till the end or adjustment value is o.
--For D3 row onwards no rounding has to be done.
ITEM_ID(B)
B          7     D1     
B          8     D2
B          9     D3     
B          5     D4
B          4     D5     
B          3     D6
Rounding for Item has to be done for the rows less then D3 and rounding value is
y and value adjustment to be done from very next row.
--For record D1 rounding to be done and value adjustment is to be done from D2 to till the end untill the adjustment value is 0.
--For record D2 (updated value has to be taken from rounding which updated in D1 row rounding) and the adjustment has to be done from very next row D3 to till the end or adjustment value is o.
--For record D3 (updated value has to be taken from rounding which updated in D2 row rounding) and the adjustment has to be done from very next row D4 to till the end or adjustment value is o.
--For D4 row onwards no rounding has to be done.
Thanks in Advance
