ADO.NET :: Stored Proc With Output Parameters / Data In The Output Parameters From The Stored Procedure?
Mar 30, 2011
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'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:.................................

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 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.

I have a GridView sourced by a SQL Server stored procedure with several databound fields, including a money column for item values. My stored proc returns the data through a SELECT and everything looks good. The stored proc also has a single output parameter that sums the total value of the displayed data, and this value is displayed in a label above the GridView.

I am having a strange problem with using stored proc in CTP5.I am calling a stored proc in my function like this:
private List<Test> GetDatat(Test pTest)
{
using(var staticDB=new StaticDB()) [code]...
But I am getting error that parameters not found. Looking at the sql trace I can see that CTP5 is sending "default" value if any of my parameters is null instead of the null value.

I 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?

When I want to get the output values its okay but I also want returning a table as a result data.But Datareader has no rows.is it possible if I want a returning query result and multiple output values togather ?I wrote a test above.I can get output values as sqlparameters. But Datareader attached to a Gridview is empty.can you detect whats wrong here and it doesnt return a query result.So stored procedure is not standart or ı am doing something wrong.this doesnt raise any exception.but not returning any data.

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')

The update option is using a stored procedure. There are no parameters fro the SP but the error message is saying that parameters are expected. If executed as SQL string then it works OK. I need to use a SP as other updates are required. Code: THIS WORKS

ConnectionString="<%$ ConnectionStrings:appConnectionString%>"
ProviderName = "<%$ ConnectionStrings:appConnectionString.ProviderName %>"
SelectCommand = "SELECT * FROM [qryNewManifestSub] where manifestid = 6855"

[RouteId], [VehicleType], [ManifestType])
VALUES (@LocationId,
CONVERT(DATETIME,@ManifestDate,103), @RouteId, @VehicleType, @ManifestType)"
UpdateCommand = "INSERT INTO dbo.tbl_DEBUG

I am building a WCF Web Service that has a Business Logic layer (that implements all validation logic and other business rules) and a Data Access Layer that makes calls to Stored Procedures in my database.
I would like to be able to validate the length of data passed against that of the length of the parameters in the Stored Procedures without having to explicitly define the parameter lengths in my WCF Web Service.
Eg:
Person Object
Person.Name = "John Dhoe"
Person.Age = 37
SQL Stored Procedure
SavePerson
FullName Varchar(15)
Age Int
In my BLL or DAL, I would like to be able to do something like :
If(Person.Name.length == SavePerson.Parameters["FullName"].Length)
{
Return true;
}
else
{
Return false;
}
Has anyone tried this out before? Is this even possible?

I'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?
