Same as any normal procedure, just make sure you add the output parameter and give it a Direction of Output (or InputOutput)
SqlParameter outParam = new SqlParameter("@myOutParam",SqlDbType.Int);<br />
outParam.Direction = ParameterDirection.Output;<br />
myCmd.Parameters.Add(outParam);

You have to use the cmd.ExecuteReader() and not the cmd.ExecuteNonQuery() - the last method return an int of numbers of rows affected, usually used with insert query or update query (also useful with select count...).
Try this:
SqlDataReader reader = cmd.ExecuteReader();
reader.Close();
string result = reader["ResultRS"].ToString();
|
|
|
|
|
it is showinf error like "Procedure or function has too many arguments specified".
i am using "paramNbr.SqlDbType = SqlDbType.Variant;" in case out parameter sqldbtype is that fine..

SqlConnection conn = new SqlConnection("CONNECTION HERE");
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "sp_abc";
//Create the first parameter
SqlParameter firstParam = new SqlParameter("P_Id", SqlDbType.Int);
firstParam.Value = 0; //Place your variable
firstParam.Direction = ParameterDirection.Input;
cmd.Parameters.Add(firstParam); //Parameter 1
//Create the second parameter
SqlParameter secondParam = new SqlParameter("ResultRS", SqlDbType.Variant);
secondParam.Direction = ParameterDirection.Output;
cmd.Parameters.Add(secondParam); //Parameter 2
int count = cmd.ExecuteNonQuery();
Console.WriteLine(secondParam.Value.ToString());
This is correct now, secondParam.Value and you read the value

I'm using an Access database in Visual C# - how can I delete a record from the database permanently? When I use .RemoveAt(int pos) it removes it only from the dataset, but when I reload the program the record is back.
|

|
|
|
You need to write delete query and execute it.

How I could get Last day of the current month in SQL Server?
I want to get records with respect to Date that lies with in the Current month or later. Please help me out.
|
|
|
|
|
AFAIK, there is no inbuilt functions available. Use Month() for comparing using month.
|
|
|
|
|
Please post this in the SQL forum. This forum is for C#.
|
|
|
|

I knocked this solution up for you:
select
dateadd(d,-1,
cast(cast(datepart(month,dateadd(m,1,getdate())) as varchar(2))+
'/'+
'1/'+
cast(datepart(year,dateadd(m,1,getdate()))as char(4))as datetime))
The way the query works is to calculate the first day of the next month then to subtract one day from this.
Regards
Guy
You always pass failure on the way to success.

Hi friends,
I have a homework, i worked for days but I got stuck in a point. I can't go out of this point.
I am very glad if you can help me.
I make effort to get a query from from northwind database sample. I want max sales of employees according to product.
There are 9 employees(sales persons). There are 77 products type. Salespersons sell this products. I want ,which product was sold maximumly according to sales turnover. The result must be like below
salesperson product sales amount
salesperson1 product a x
salesperson2 product b y
. .
. . .
.
salesperson9 product h w.
I tryed below script, I can find max sales of each salespersons but I can't add productname column to this query.
select t.firstname,t.lastname,max(t.sales) as sales
from (select employees.Firstname,employees.lastname,products.productname,
sum("order details".unitprice*quantity*(1-discount)) as Sales from ((Employees inner join orders on employees.employeeID=orders.employeeID) inner join "order details" on orders.orderID="order details".orderID) inner join products on products.productID="order details".productID
group by employees.lastname,employees.firstname,products.productname
) as t
group by t.firstname,t.lastname
order by t.firstname
Note: I got answer from Jacob Sebastian like below, bu i didn't understand exactly that response. It works but I didn't understand, especially top1 clause. The result consists of 9 row but top1 gives one row according to I know and link between a and b is very complex.
SELECT
FirstName,
LastName,
(SELECT TOP 1 ProductName FROM (SELECT
e.FirstName,
e.LastName,
p.ProductName,
SUM(od.UnitPrice * od.Quantity*(1-Discount)) AS Sales
FROM Orders oh
INNER JOIN [Order Details] od ON oh.OrderID = od.OrderID
INNER JOIN Products p ON p.ProductID = od.ProductID
INNER JOIN Employees e ON e.EmployeeID = oh.EmployeeID
GROUP BY e.FirstName, e.LastName, p.ProductName ) b
WHERE a.FirstName = b.FirstName AND a.LastName = b.LastName
ORDER BY Sales DESC
) AS ProductName,
MAX(Sales)
FROM (
SELECT
e.FirstName,
e.LastName,
p.ProductName,
SUM(od.UnitPrice * od.Quantity*(1-Discount)) AS Sales
FROM Orders oh
INNER JOIN [Order Details] od ON oh.OrderID = od.OrderID
INNER JOIN Products p ON p.ProductID = od.ProductID
INNER JOIN Employees e ON e.EmployeeID = oh.EmployeeID
GROUP BY e.FirstName, e.LastName, p.ProductName
) a
GROUP BY FirstName, LastName
ORDER BY FirstName, LastName

Please post this on the SQL forum, especially as you have had this answered before. It's only polite to continue this on the original thread.

That's an abuse of the forum system. How do I find an answer to a problem in future if it's not in a logical area? Why not ask a C# question in the C++ forum because the syntax is a little bit similar? There's a reason why these forums are organised the way they are, and it's not to provide a shortcut for somebody who's too lazy or incompetent to use the appropriate forum.

Ok the following is a lambda:
Func<..> func = i => i * 3;
And this is an anonymous delegate
Func<..> func = delegate (int i) {return i * 3; ) ;
But what about this?:
Func<..> func = (int i) => { return i * 3;}
Is this considered a lambda, due to the fact it uses the lambda syntax..
Or is it considered an anonymous delegate due to the fact that it can not be converted to an linq.expression
Im I right if I say that it is infact an anonymous delegate and that only the "one line" forumulas w/o any { } body are real lambdas?
If it is considered a lambda, since it uses the lambda syntax after all. and it also benefits from type deduction and all that.
Is there any word or way to make a difference between one line lambdas that can be turned into linq.expressions and those that only can fill the role of plain old delegates?
