Stored procedure or function expects parameter which is not supplied
- by user2920046
I am trying to insert data into a SQL Server database by calling a stored procedure, but I am getting the error
Procedure or function 'SHOWuser' expects parameter '@userID', which was not supplied.
My stored procedure is called "SHOWuser". I have checked it thoroughly and no parameters is missing.
My code is:
public void SHOWuser(string userName, string password, string emailAddress, List preferences)
{
SqlConnection dbcon = new SqlConnection(conn);
try
{
SqlCommand cmd = new SqlCommand();
cmd.Connection = dbcon;
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "SHOWuser";
cmd.Parameters.AddWithValue("@userName", userName);
cmd.Parameters.AddWithValue("@password", password);
cmd.Parameters.AddWithValue("@emailAddress", emailAddress);
dbcon.Open();
int i = Convert.ToInt32(cmd.ExecuteScalar());
cmd.Parameters.Clear();
cmd.CommandText = "tbl_pref";
foreach (int preference in preferences)
{
cmd.Parameters.Clear();
cmd.Parameters.AddWithValue("@userID", Convert.ToInt32(i));
cmd.Parameters.AddWithValue("@preferenceID", Convert.ToInt32(preference));
cmd.ExecuteNonQuery();
}
}
catch (Exception)
{
throw;
}
finally
{
dbcon.Close();
}
and the stored procedure is:
ALTER PROCEDURE [dbo].[SHOWuser]
-- Add the parameters for the stored procedure here
(
@userName varchar(50),
@password nvarchar(50),
@emailAddress nvarchar(50)
)
AS
BEGIN
INSERT INTO tbl_user(userName,password,emailAddress) values(@userName,@password,@emailAddress)
select tbl_user.userID,tbl_user.userName,tbl_user.password,tbl_user.emailAddress,
stuff((select ',' + preferenceName from tbl_pref_master
inner join tbl_preferences on tbl_pref_master.preferenceID = tbl_preferences.preferenceID
where tbl_preferences.userID=tbl_user.userID
FOR XML PATH ('')),1,1,' ' )
AS Preferences
from tbl_user
SELECT SCOPE_IDENTITY();
END
Pls help, Thankx in advance...
