Prefix your parameter names with @ symbols.
BTW, you should consider not using inline SQL statements. Use stored procedures instead.

i thought about using stored procedures only i don't know exactly how to do this.(oracle fan) and by the way....even with the @ symbol in front of the parametername i still get the exact same error.

You don't need to do any string concaternation here.
You should still really consider using stored procedures instead - you wouldn't have these problems if you did.

ALTER PROCEDURE [dbo].[uspGetBirthdayFriends]
@CRK INT
@BDATE SMALLDATETIME
AS
begin
select * from Friends where UserID=@CRK and FBirthday =@BDATE
RETURN
end
same error
incorrect sintax near '@BDATE'
must declare scalar variable "@crk"

You have made a syntax error. Each parameter declaration should be separated by a comma.

Thank you. That worked. But now i get another error and i can't seem to determine the cause
after i invoke
adapt.Fill(ds);
/*This is the code of the procedure*/
ALTER PROCEDURE dbo.uspGetBirthdayFriends
@CRK INT,
@BDATE SMALLDATETIME
AS
begin
declare @ID int
declare @BDATE smalldatetime
select * from Friends where UserID=@ID and FBirthday =@BDATE
end
RETURN
i get the following error "Procedure uspGetBirthdayFriends has no parameters and arguments were supplied."
Thank you

You've declared @BDATE twice in your SP - once as a parameter and secondly as a variable. This code won't complile - remove your variable declaration.

You should really pass @ID in. Change it to:
dbo.uspGetBirthdayFriends
@ID INT,
@BDATE SMALLDATETIME
AS
begin
select * from Friends where UserID=@ID and FBirthday =@BDATE
end
RETURN From what I saw of your earlier post, you also seem to have a problem with the way you are handling your parameter. When you add in the SqlParameter, you need to put the parameter in with an @ in front of the name, e.g. command.Parameters.Add(new SqlParameter("@ID", SqlDbType.Int));

Thank you very much. Both of you. I finaly solved the problem.

Check your query. Does it return any data if you run it through Access?

Look at Mike's reply[^]. What he says is correct. You are using the SQL Server classes when you should be using the OleDb classes.

That's an OLE DB connection string to use the Jet database engine in-process. It won't work for SQL Server.
If you want to connect to SQL Server, use a SQL Server connection string. If you want to use Jet with that connection string, use OleDbConnection.

i cant solve this problem 
adding with this cmd ;
cmdInsert.Parameters.AddWithValue("@RECORD_DATE", DateTime.Today.ToString("dd/MM/yyyy"));
Gettin' this error.
Arithmetic overflow error converting expression to data type datetime.
|
|
|
|
|
What's wrong with:
<br />
cmdInsert.Parameters.AddWithValue("@RECORD_DATE", DateTime.Today);
What data type is record_date?
|
|
|
|
|
oops i found problem.. Problem is my sql command . i was changing datetime.today to string and getting error. thanx for help Paddy Boys .
|
|
|
|
|
there is one small thing
cmd.CommandText = "SELECT KODU,CDISMI,CDTURU,CDADET,ACIKLAMA FROM TBL_PS_2" +
" WHERE RECORD_DATE BETWEEN '" + txtDate1.Text + "' AND '" + txtDate2.Text + "' ";
but getting error about datatype char conversion to datetime bla bla.

Be careful to send the DateTime-value to the Sql-Server in the right format. If your database-language is set to English(US), maybe you should try to convert the DataTime to this format with a CultureInfo-object.
<br />
CultureInfo ci = new CultureInfo("en-US");<br />
DateTime begin = DateTime.Parse(txtDate1.Text, ci);<br />
DateTime end = DateTime.Parse(txtDate2.Text, ci);<br />
Your SQL-command should then look like this:
cmd.CommandText = "SELECT KODU,CDISMI,CDTURU,CDADET,ACIKLAMA FROM TBL_PS_2" +
" WHERE RECORD_DATE BETWEEN '" + begin.ToString() + "' AND '" + end.ToString() + "' ";
Maybe this solves your problems.

cmd.CommandText = "SELECT KODU,CDISMI,CDTURU,CDADET,ACIKLAMA FROM TBL_PS_2" +<br />
" WHERE RECORD_DATE BETWEEN '" + txtDate1.Text + "' AND '" + txtDate2.Text + "' ";<br />
Just for your info, that would be subject to dangerous sql injection attacks.

Hello Forum!
Here is my problem: I have a table called TblArticle (artnr, comment) and a table called TblArticlemoves (autoid, artnr, quantity, date). Now I need a report that looks like the following example:
artnr ....|01.11.07 | 02.11.07 | 03.11.07 | 04.11.07 | 05.11.07 | ...
A ........| 20 ........| 20 .........| 35.......... | 45 ........| .........15 | ...
B........ | 5 ..........| 15......... |.25 ..........| 5 ......... | ..........20 | ...
.
.
.
The main thing is I need to display each day of a month, but I 'm not having an entry for each day of a month in my table TblArticlemoves. Therefore i need to calculate the stock quantity for each day of the month. How can i do this?
regards adyck
