I have a question. How do we define date output parameters for a stored procedure?
before you answer,I should mention that I am not referring to the sql syntax definition ,which is @mydate datetime output.
This is ok,what i am asking is HOW DO I SPECIFY IT IN LINQ WHEN I NEED TO CALL THE STORED PROCEDURE IN THE SERVER SIDE CODE. I am repeating that I do I am not referring to the sql definition .
I have a stored procedure that works fine for classic asp, but how can I get my output parameters data back from in /MVC 2 / linq/ entities framework model . I have inported the function also, but when i try to code it i dont get results ...i know this is a matter of lack of / knowledge or exmple because i have been scouring the web for it and cannnot find into that accually works.
here is the stored proc.
[Code]....
Here was the one of the few tries I did:
[Code]....
but it executes fine does not give me an error, but also does not return the info i need to the viewmodel
I keep seeing stuff about "ref" on the net but "ref" shows " arbument # should not be passed with the ref keyword.
So i am not sure if there is a problem with the model, or with my understanding this, Now for your info I can do the same step with returning a dataset from a stored procedure fine, but I dont want a data set I just want excatly the data in the output parameters from the stored procedure.
I have never used stored proc ouput parameters i want to know what is the use of using output parameters?If possible provide me some code.
View 10 Repliesi had a stored proc: How can i get the final select statement in the code behind.

From this below stored Procudure, using VB.Net code can i get the Values like "Number of Rows Affected" and "Yes / No" Value from "Select"Stored Procudure:ALTER PROCEDURE [dbo].[lookup] @week_date datetimeAS

IF @week_date = '10/14/2010'

UPDATE dbo.work_status SET ob_flag = 0, ob_update_date = NULL WHERE dbo.work_tatus.week_date ='10/14/2010'
SELECT 'YES'
END
ELSE
SELECT 'NO'
RETURN 0
I have several VB.NET functions which pass and receive values from executed stored procedures using parameters. However, the latest method I am using seems to be a little too specific on the datatype and data length of the parameters for my liking (i.e.
LogActivityCommand.Parameters.Add("@strErrSource", SqlDbType.NVarChar, 300).Value = strErrSource). For example:
[code]....
If I end up changing the datatype and data length properties of the variables in my SQL stored procedures in the future, I am going to have to re-visit my VB code too and alter the parameter settings here as well.
how do I add an output parameter to a Stored Procedure that returns a code or string to the calling app
View 1 RepliesI am having some trouble with the below code snippet. It is a stored procedure which executes on load that has an output parameter which should display in a label. Familiar which Vb however not so much in C#.
View 2 RepliesI am calling a stored procedure, that exists in a SQL Server 2005 database, using ADO.NET, in which I instantiate a sql command object.
The stored procedure has an ouput variable like '@packageCode VARCHAR(100) = NULL OUTPUT'.
Can I set it's value when creating the sql command object? Or I can never set a value for an output type variable in a stored procedure?
I have a stored procedure with the following structure:
[Code]....
I've modified an existing strored procedure. It originally had one ouput parameter in the stored proc and it was set up as follows in the c# code that called it:
cmd.Parameters.Add("@Var1Param", SqlDbType.BigInt);
if (Var1 == 0)
cmd.Parameters["@Var1"].Value = DBNull.Value;
else
cmd.Parameters["@Var"].Value = Var1;
cmd.Parameters["@Var1"].Direction = ParameterDirection.InputOutput;
cmd.ExecuteNonQuery();
// Get Var1
Var1= dataMorph.ToInt64(cmd.Parameters["@Var1"].Value.ToString());
Just to clarify, this parameter was declared as OUTPUT in the stored proc but as inputoutput in the C# code. This worked fine. I have added another parameter to the same stored procedure and I want to retrieve both from the C# code. The C# code now is as follows:.................................

We had a simple Gridview that displayed a column list as Linkbuttons but we now need to display three columns as one, so I wrote a simple stored procedure to do it. However, the output in the Gridview shows duplicates and is not in order even though I specifySELECT DISTINCT in the result select as shown below.
ALTER PROCEDURE [dbo].[GetGeneralAction]
Add the parameters for the stored procedure here
AS
BEGIN
SET NOCOUNT ON;
CREATE TABLE #TempTbl (GeneralAction varchar(300) )
INSERT INTO #TempTbl (GeneralAction)
SELECT [General Action]
FROM [dbo].[Formulary2011]
INSERT INTO #TempTbl (GeneralAction)
SELECT [General Action2]
FROM [dbo].[Formulary2011]

here my code-
using (SqlDataReader sqlDataReader = ExecuteReader(CommandType.StoredProcedure, StoredProcedures.AuthenticateUser, sqlParameter))
{
isAuthenticated = Convert.ToBoolean(sqlParameter[2].Value);
if (isAuthenticated)
{
if (sqlDataReader.Read())
{
User = new UserEntity();
DbHelper.GetEntity(sqlDataReader, User);
}
}
}
I always get isAuthenticated as false because sqlParameter[2].Value is null all the time but when I execute my query with ExecuteNonQuery it gives me the value but in that case I can not fill the entity.
I have stored procedure that increments a number. I am supposed to use the newly generated number and insert it into a table. My question is how do I execute the stored procedure, with a hardcoded value of 3 that it expects as a paramter, receive the number it generates as the output parameter and use it in the insert statement.
Here is the stored procedure code:
CREATE PROCEDURE [dbo].[Generate]
@myid int,
@next_no int output
AS
update mytable
set mynumber=mynumber + 1, @next_no = number
where myid=@myid
RETURN
Here is my insert statement, that I tried and it failed:
EXEC @GetNo = Generate '3'
Insert into customers (custid, name, phone ) values
( @GetNo, 'MSFT', '800-345-5678')
I am creating a nightly process using a stored procedure to check for expiring records and emailing myself and the folks that need to see the information.

View 5 RepliesI'm having trouble figuring this error out. I have a grid on an ASPX page that displays data from a stored procedure in an SQL Server 2008 database. When the page loads, I get the following error:
"Procedure or function <sp_name> has too many arguments specified."
Here is the code for the grid and the datasource:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" ShowFooter="True" OnRowDataBound="GridView1_RowDataBound"
AllowSorting="True">
[code]....
Here's the code from the stored procedure:
ALTER PROCEDURE [dbo].[sp_GatewayMerchants]
-- Add the parameters for the stored procedure here
@StartDate DateTime,
[code].....
The datasource is passing 4 parameters, and the stored procedure is accepting 4, but when the page displays I get the error mentioned above.
EDIT: Here's the code behind for the template column. But I'm not sure how this could be causing extra parameters to the SP.
protected void Command_Click(object sender, EventArgs e)
{
var merchantID = Convert.ToInt32(((LinkButton)sender).CommandArgument);
[code].....
If I remove the ASP:LINKBUTTON the code works. So why would a LINKBUTTON be causing this?
I need to update a table with values from a listbox. I am trying to create as many parameters as there are items in the list, my code below, but how do i name them differently? so that they dont' overwrite each other?
For Each item As ListItem In ris
Dim pID As New SqlParameter("@userid", SqlDbType.Int)
pID.Value = objFormat.CheckSQL(item.Value)
myCommand.Parameters.Add(pID)
Next
and on the SQL side, is it possible to write an update statement, that will take a dynamic number of parameters?
so for example, i need to update multiple users with the same value in the "active" field...

i have a stored procedure to update a table. not all fields are required and some can be blank.for example, title is not required, but when it's blank i get an error

myCommand.Parameters.Add(ptitle)
ex {"Procedure or Function 'sp_UpdateUser' expects parameter '@title', which was not supplied."} System.Exception
how can i fix it so that it allows for nulls if the data field is blank?
