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.
The sql string I used
sql = "DELETE Audio_Extension.ID, Audio_Extension.AudioExtension FROM " + _
"Audio_Extension WHERE (((Audio_Extension.AudioExtension)='" + ExtDel + "'));"

If diagReceive = 2 Then
retError = dbExtDel.DeleteSQL(sql)

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,

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.

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.

Hello, i have some visual foxpro tables and i try to insert data into them using ole db. I have the following command:
INSERT INTO comanda_a (comanda, data, agent, sofer, client, magazin, discount)
VALUES ('2', '07/20/2007', 104, 1, '10016705', 2, 30)
the comanda_a table looks like this:
---------------------------
comanda | OleDbType.Char
data | OleDbType.DBDate
agent | OleDbType.Integer
sofer | OleDbType.Integer
client | OleDbType.Char
magazin | OleDbType.Integer
discount| OleDbType.Double
---------------------------
After the insert i get a data type mismatch error, i dont know which column.
I never used ole db before, (but i know the sql commands,) if u know some links or tutorials please post them also.
In the meantime i have found a way to insert rows using parameters(in c#).
any help would be greatly appreciated.

Using parameters would be the recommendation in any case, since this is a generally more robust solution and avoids the likelihood of sql injection attacks by malicious users. It is most likely the date column that is complaining, or the double column (need a .0?). Parameters solve this by providing a more explicit opportunity for the data conversion, and they encapsulate the variables in the query, minimizing chances for SQL injection from the UI.

i have string of ids which i am passing as an string like 11,33,454,34,...
now i want to separate this string n do
IF EXISTS (SELECT DISTINCT chRoleId
FROM Users WHERE chRoleId=@RoleIDs)
like this stuff.
that is i need to split the comma separated string . can anyone help me to do it in the stored procedure.
thanks in advance.

Well, you can use the CHARINDEX, SUBSTRING, LENGTH and LEFT commands to achieve this effect. In pseudo code, you need to do the following:
Create in-memory table
While length of your string > 0
Get the first part of the string (up to the ,) and insert this into your in-memory table.
Remove the first part of the string from the string (including the comma)
End while
select from your table where the users are in the in-memory table.

You really have to use better names for things. Lable5 and TextBox3 really don't help anyone understand your code.

Also, why are you puttin String.Empty inside quotes. This will display the string value "String.Empty", rather than the empty string ""...
