  [font="Verdana"]Hi,

  i am writing the sp for sales report

  i have doubts

  create table #temp

  (

  slno int,

  sale_order Nchar(15),

  order_value numeric(13,8),

  budget Nchar(15),

  budget_amt numeric(13,8),

  budget_balance numeric(13,8)

  )

  insert into #temp values

  (1,'ESA-01/08',150.00,'CAP-A/08',1500.00,0.00)

  go

  insert into #temp values

  (2,'ESA-02/08',300.00,'CAP-A/08',1500.00,0.00)

  go

  insert into #temp values

  (3,'ESA-05/08',450.00,'CAP-B/08',1500.00,0.00)

  but i am using the updates like

  update #temp

  set budget_balance = case when slno = 1 then budget_amt-order_value

  when slno <> 1 and budget in (select budget from #temp where slno = slno - 1)then (select budget_balance from #temp where slno = slno - 1) - order_value

  when slno <> 1 and budget not in (select budget from #temp where slno = slno - 1)then budget_amt - order_value

  end

  but it's not work

  help how to do without while/cursor to get result with simple

  There are many articles on this forum that solves the running total problems....

  Here is one of the article by Jeff Moden on Solving the "Running Total" & "Ordinal Rank" Problems in SS 2k/2k5[/url], though this article is under the process of re-write (as Jeff found some corrections to be made to 2K5 solutions), it has a SQL 2K solution for it.

  I don't think you have read the entire article, it clearly has an example of running totals with pre-available scripts. Please spare some time in reading the article & understanding the logic behind it. From that, you try to modify the query to suit your requirements and if in case you have problems in it, then we are here to help you on that.

  Hi,

  Thanks Ramesh,

  I already understood this concept,

  I too wrote this update statement, see the earily,

  All I need is how I solve this without using while.

  Arun,

  You did a great job by including the table creation script and insert statements to populate it.

  I have seen too many times a question asked without making the effort. You stand out amongst these.

  Here is a solution, based on the article everyone mentioned and is also listed below in my signature block.

  create clustered index IX_RunningBal on #temp (

  budget asc,

  slno asc

  )

  select * from #temp

  declare @bbal numeric(13,8),

  @bud Nchar(15);

  set @bud = '';

  update #temp set

  @bbal = [budget_balance] = case when @bud <> [budget] then [budget_amt] else @bbal end - [order_value],

  @bud = [budget]

  from

  #temp with (index(IX_RunningBal));

  select * from #temp

  ARUN SAS

  Absolutely. And, since you can't use an index by name in the from clause that is created in the same script, you need to modify Lynn's code as follows...

  update #temp set

  @bbal = [budget_balance] = case when @bud <> [budget] then [budget_amt] else @bbal end - [order_value],

  @bud = [budget]

  from

  #temp with (index(0));

  I would not have known that, and not that I don't believe Jeff, I am going to have to test it out for myself. When I wrote the code earlier, I did it in pieces which may explain why it worked for me at the time.

  Jeff, I'm not sure if you are right or wrong still. I ran the following and everything ran fine. Can you suggest any other tests I may want to try?

  create table #temp

  (

  slno int,

  sale_order Nchar(15),

  order_value numeric(13,8),

  budget Nchar(15),

  budget_amt numeric(13,8),

  budget_balance numeric(13,8)

  );

  insert into #temp values

  (1,'ESA-01/08',150.00,'CAP-A/08',1500.00,0.00);

  insert into #temp values

  (2,'ESA-02/08',300.00,'CAP-A/08',1500.00,0.00);

  insert into #temp values

  (3,'ESA-05/08',450.00,'CAP-B/08',1500.00,0.00) ;

  insert into #temp values

  (4,'ESA-06/08',500.00,'CAP-B/08',1500.00,0.00);

  insert into #temp values

  (5,'ESA-07/08',600.00,'CAP-B/08',1500.00,0.00);

  insert into #temp values

  (6,'ESA-10/08',50.00,'CAP-C/08',1500.00,0.00);

  insert into #temp values

  (7,'ESA-11/08',150.00,'CAP-C/08',1500.00,0.00);

  insert into #temp values

  (8,'ESA-12/08',250.00,'CAP-C/08',1500.00,0.00);

  create clustered index IX_RunningBal on #temp (

  budget asc,

  slno asc

  );

  select * from #temp;

  declare @bbal numeric(13,8),

  @bud Nchar(15);

  set @bud = '';

  update #temp set

  @bbal = [budget_balance] = case when @bud <> [budget] then [budget_amt] else @bbal end - [order_value],

  @bud = [budget]

  from

  #temp with (index(IX_RunningBal));

  select * from #temp;

  drop table #temp;

  My bad, Lynn... the problem I mentioned only exists in versions prior to 2k5. I still do a lot of testing in 2k to make sure the solutions I provide still work there and here's the error you'll get if you run it in 2k...

  [font="Courier New"]Server: Msg 308, Level 16, State 1, Line 39

  Index 'IX_RunningBal' on table '#temp' (specified in the FROM clause) does not exist.[/font]
