How about trying to itrate this from Front-End and thereby updating the column in the DB accordingly?

I thought of using asp.net with vb script. But I think then also we need to write appropriate sql statements only.

What you are looking for is a cursor (at least if you are using sql server).
cursors allow you to iterate through a set of results returned by a select statement and perform any number of sql actions on each iteration. Be careful though as SQL is designed for Set based actions not iterative procedures so the performance overhead against a properly designed query (if one would be possible for what you want to do) is huge.
Just google for 'SQL Cursor' and you should find what you want.

I dont know whether i have to use cursor or simply a stored prcedure.
This is FIFO inventory system. Recieved and Issue items will be in different table say, RECIEVE & ISSUE. Each item may be recieved and issued many times. Each time may be with different rate,quantiy and date. For example let us considere the following tables,
RECIEVE TABLE
PARTNO RDATE RRATE/UNIT rQUANTITY
A 10/10/2006 15 20
A 10/10/2007 20 50
A 1/11/2006 18 10
B 10/12/2006 15 30
B 13/2/2007 25 15
ISSUE TABLE
PARTNO IDATE IRATE/UNIT iQUANTITY
A 10/5/2007 18 18
A 1/12/2007 20 45
A 13/2/2007 20 15
B 13/2/2007 20 20
B 1/5/2007 20 25
Ultimately i have to get the following table
PARTNO IDATE IRATE/UNIT iQUANTITY ShortTerm LongTerm
Here I want to find the LongTerm Value and Shorttem value depending on the difference in date between idate and rdate of each item. This is to find the gain or loss of the item in that particular date. The formula is iquatity(irate)+iquatity(irate-rRate),if the date difference between recieve and issue is >365 day then the calculated value should be place in LongTerm value column else in the Short term value column
First we take A, the first issue quanitity is 18, but the no of quantity recieved was 20 so the value will be 18(18)+18(18-15). Now the remaining no of items present in first recieved is 2.The difference between issue date 10/5 /2007 and recieve date 10/10/2006 is less than 365 days so has to be placed in ShortTerm column.
So when calculating the amount of second issue first we have issue remaining 2, then go for second recieve. Here issue quantity is 45. so, the value must be (2(20)+2(20-15)). The difference between issue date 1/12/2007 and recieve date 10/10/2006 is more than 365 days so has to be placed in LongTerm column. Then remaining 43 items, the value has to be (43(20)+(43(20-20). The difference between issue date 1/12/2007 and recieve date 1/12/2007 is less than 365 days so has to be placed in ShortTerm column. Now the remaining items in Recieve table for A item is 7+10.
Now we have to calculate the next A item as we did for second. i.e. first issuing 7 items from the remaining RECIEVE and then another 8. So we are left with 2 recieved items which will be there until next issue.
This has to be repeated for the Item B and so on.

I have written following sqlstatements to update a column based on the no of days between two dates. but it is giving the error,
Server: Msg 512, Level 16, State 1, Line 2
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
In what other way i can get the expected result
if (select datediff(dd,transactiondate, Issuedate) from receipt)>365
begin
update receipt set longvalue=datediff(dd,transactiondate, Issuedate)
end
else
begin
update receipt set shortvalue=datediff(dd,transactiondate, Issuedate)
end

Use a WHERE in the UPDATE
UPDATE receipt set longvalue=datediff(dd,transactiondate, Issuedate)
WHERE datediff(dd,transactiondate, Issuedate) >365
UPDATE receipt set shortvalue=datediff(dd,transactiondate, Issuedate)
WHERE datediff(dd,transactiondate, Issuedate) <= 365

Hi,
I want to find the date difference of date1 and date2. But these two colums are present in different tables. I have used joins but not getting proper results because the no of rows i am getting is the cartesian product of the two tables. I am includeing two tables and the result i have got after using joins. Please tell the right way to do this.

Hallo
for the overview I only copied the code wich is necessary to, I hope, solve my problem.
1. With the following command line "retError = dbExtDel.DeleteSQL(sql)" I am deleting one recordset from my table. [Succsessful]
2. With the following command line "arrMedExtension = ReadExtensions(retError)" I import the data from my table with the before deleted record again. [Unuccsessful]
Even the record has been deleted in the first step, in the second step I still can see the deleted record. If I insert the command line " System.Threading.Thread.Sleep(1000)" an wait for a litle while sometimes it is Succsessful but not ever. It seems that it is a timing problem but I cant find the cause. Can anybody assist me to solve my problem ?
Thanks in advance.

"Audio_Extension WHERE (((Audio_Extension.AudioExtension)='" + ExtDel + "'));"

Hii,
I have a MSDE or SQL sever, it is logging the data from an instrument continuously. I want to genarate an Report on Excel sheet on daily basis and separate Monthly basis, which should happen automatically.
In this case,
For, Daily report,each hour data has to be reported in MS-Excel sheet by row wise in the perticular column. 00:00 hrs to 24:00 hrs data should be updated frm SQL sever or MSDE to Excel sheet. In another column of Excel, 01:00-00:00(subtraction) hr data should be updated as a subtracted result, 02:00-00:00 hr data likewise for 24:00 hr, 24:00-00:00 hr data to be updated (From each hour 00:00 hr's data to be subtract), and below side of the excel sheet, all these 24 subtracted result should be added and this is the Result. All this things happen automatically.This is the daily report.
In the monthly Reoprt, all the result of the daily report update in another excel sheet row wise for each day and after the complition of month, all data's to be added and it will be the result in that report.
So please give me the solution regarding this. This Reports should genarate automatically.
With regards,
Ravisubrahmnaya

Sounds like you have the start of a nice spec for a reporting application including a scheduler. It could be implemented in C# using the System.Data.SqlClient classes to read the SQL data and System.Data.Oledb classes to write the Excel spreadsheet.
Another alternative would be to use SQL Server reporting services, since this could also provide the scheduling aspect.

Hii,
Pls, help me to restore MSDE sever data in to SQL server database.

Since MSDE IS SQL Server, just back up your MDE data nad then use SQL Server to restore it to an SQL database.

Every thing is going well.Above procedure show report properly.i show all of my report using procedure similar to above procedure.in each procedure only binding source & report name & dataset is changed.
when i run my application then reportviewer control show some of my report.if i again restart my application then it show also remaining report. so i am sure there is no error in my procedure.
my problem is that reportviewer control does not show all report.some of report is generated properly while some of report show message "Report is being Generated". This message is appear until i do not close form related to reportviewer. However next time it show this report(mean when i restart my application).i don't know where i am wrong
Please guide me where i am wrong ? or provide some link.

Hi
I want to select records from last two days, the following query does not return any record.
select * from tablename where datefield = dateadd(day,-2,Getdate())
Any help will be appreciated.

The = sign is your problem. Try >=, otherwise you're only asking for records that have exactly the same time as today, but two days ago.

Try the following solutions:
1) use the abbreviations 'd' OR 'dd' inplace of day in your syntax.
2) Check out your table. Are you storing your data alongiwth the time in the database. If yes then this query will never return any result

i have th followwing qury and i need to show only one record for the customer that is last transiction that he done.
i have three tables and i write the query
SELECT cust_order.order_id AS order_id, customers.fname AS fname, customers.lname AS lname, cust_order.order_date AS order_date, cust_order.order_status AS order_status
FROM cust_order, customers WHERE cust_order.customer_id=customers.customer_id cust_order.order_id In (SELECT DISTINCT order_id
FROM cust_debit WHERE amount>=2000) AND cust_order.customer_id=customers.customer_id and cust_order.customer_id in ( SELECT DISTINCT customer_id FROM cust_order
WHERE order_id IN ( SELECT DISTINCT order_id
FROM cust_debit WHERE amount>=2000);
in which i get the distinct customers from the
SELECT DISTINCT customer_id FROM cust_order
WHERE order_id IN ( SELECT DISTINCT order_id
FROM cust_debit WHERE amount>=2000
when i run the query individually i get distinct(one record for the customer) but when i run the above whole query i got all order which the customer place.
plz its urgant i need ur help

Please stop using text speak. Read the forum guidelines. Also, we don't care if it is urgent or not.

I know this was urgent for you, but I didn't see you offer to pay for a solution, so I wasn't sure just how urgent it really was. Nevertheless, I did take a few minutes and try to read your select statement. I'm really blind about these things so I took the liberty of reformatting it a bit so I could see what was going on:
SELECT cust_order.order_id AS order_id
, customers.fname AS fname
, customers.lname AS lname
, cust_order.order_date AS order_date
, cust_order.order_status AS order_status
FROM cust_order, customers
WHERE cust_order.customer_id=customers.customer_id
? cust_order.order_id IN (SELECT DISTINCT order_id
FROM cust_debit
WHERE amount>=2000)
AND cust_order.customer_id=customers.customer_id
AND cust_order.customer_id IN (SELECT DISTINCT customer_id
FROM cust_order
WHERE order_id IN (SELECT DISTINCT order_id
FROM cust_debit
WHERE amount>=2000)?;
Apart from putting in spaces, carriage returns, and changing case on a couple of reserved words, I've also placed two '?' marks where I don't understand the query. The first one SEEMS to have a missing operator. The next one SEEMS to have a missing ')'. You said you are running this query and getting results, so I guess I don't understand the dialect you are using. Would it be possible for you to re-write the intention of the query in a dialect I could understand, and re-post it? If so, I might be able to look at it a couple of minutes and POSSIBLY offer some suggestions.
