I am creating an ASP.NET Wiki for myself to track the knowlege I gain in C# and other language.
I have created a Stored Procedure to insert a category into a DB, the DB has two fields C_ID(int) and Category(varchar 25). In my ASP page, there is no field for C_ID, it increments automatically by IsIdentiy = true;
When I try to excute it, it fails. What is the best approach to handle this?
Code:
ALTER PROCEDURE dbo.InsertCategory
@ID int,
@CATEGORY varchar(25)
AS
INSERT INTO Wiki
(C_ID, C_Category)
Values (@ID, @CATEGORY)
/* SET NOCOUNT ON */
RETURN
Did I miss something to insert from the .aspx page?
try
{
//create a command object identifying the Stored Procedure
SqlCommand cmd = new SqlCommand("InsertCategory", conn);
//Set the command type
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("Category", txtAddCatagory));
cmd.ExecuteNonQuery();
I have a working controller for another stored procedure in the database, but I am trying to test another.
When I request the URL; http://host.com/Map?minLat=0&maxLat=50&minLng=0&maxLng=50
I get the following error message, which is understandable but I can't seem to find out why it occurs;
Procedure or function 'esp_GetPlacesWithinGeoSpan' expects parameter '@MinLat', which was not supplied.
This is the code I am using.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web; [code].....
I am goig to execute an oracle store procedure using C# through through ODP.NET. The store procedure executes succsfully but it does not return any value in the out parameter.
When I execute the same store procedure with the same input parameteres from within SQL*Plus. It does return values.
This is to be clearify here that in the oracle store procedure the data type for the out parameter is number and in the c# the variavle that will hold its value is Integer. I also tried using Long on the C# side but it is still not working. After the successfull execution of the store procedure the C# variable contains nulll value.
I have created a stored procedure shown below ,how will i call this from c# code behind to get the result and results are stored in dataset.
USE [Test]
GO
/****** Object: StoredProcedure [dbo].[tesproc] Script Date: 09/01/2010 13:00:54 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[tesproc]
-- Add the parameters for the stored procedure here
@a float, @b float, @c float,@d int
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
select Id, Name1,ZipCode,StreetName,StreetNumber,State1,Lat,Lng, ( 6371 * ACOS( COS( (@a/@b) ) * COS( (Lat/@b) ) * COS( ( Lng/@b ) - (@c/@b) ) + SIN( @a/@b ) * SIN( Lat/@b ) ) ) as distance from business_details where ( 6371 * ACOS( COS( (@a/@b) ) * COS( (Lat/@b) ) * COS( ( Lng/@b ) - (@c/@b) ) + SIN( @a/@b ) * SIN( Lat/@b ) ) )<@d
END
If i execute this stored procedure in sql server its working fine with this following call
exec dbo.tesproc 12.9216667 ,57.2958,77.591667,1
I have several store procedure to do different things. When user click submit button, call store_procedureOne, store_procedureTwo, store_procedureThree.
Here is my code.
protected void ButSubmit_Click(object sender, EventArgs e)
{
OleDbConnection myConnection = new OleDbConnection(connStr);
OleDbCommand myCommandUpdate = new OleDbCommand("store_procedureOne");
myCommandUpdate.Connection = myConnection;
myCommandUpdate.CommandType = CommandType.StoredProcedure;
myConnection.Open();
myCommandUpdate.ExecuteNonQuery();
myConnection.Close();
Server.Transfer("NextPage.aspx", true);
}
I do not know how to add store_procedureTwo and store_procedureThree at
OleDbCommand myCommandUpdate = new OleDbCommand("store_procedureOne");
I would like to know if there is a way to call Oracle stored procedure from inside code?

View 3 RepliesI have Asp.net application which I have created on the vista 32 using vs 2005.Which uses MSDAORA provider to connect to oracle,which works fine.ut when we are deploying on windows 2003 server 64bit it is giving the below error:Excetion: System.InvalidOperationException: The 'MSDAORA.1' provider is not registered on the local machine.I have search on the google for the solution and found that:switch the appication to 32 bit and use a 32 bit Oracle client'vider instead (Ie, Oracle's provider - ORAOLEDB.ORACLE)ORAOLEDB.ORACLE and it will work.

View 8 RepliesI'm using the ASP.NET SQL Membership Provider. So, there's an aspnet_Users table that has details of each of my users. (Actually, the aspnet_Membership table seems to contain most of the actual data). I now want to store some per-user information in my database, so I thought I'd just create a new table with a UserId (GUID) column and an FK relationship to aspnet_Users. However, I then discovered that I can't easily get access to the UserId since it's not exposed via the membership API. (I know I can access it via the ProviderUserKey, but it seems like the API is abstracting away the internal UserID in favor of the UserName, and I don't want to go too far against the grain).
So, I thought I should instead put a LoweredUserName column in my table, and create an FK relationship to aspnet_Users using that. Bzzzt. Wrong again, because while there is a unique index in aspnet_Users that includes the LoweredUserName, it also includes the ApplicationId - so in order to create my FK relationship, I'd need to have an ApplicationId column in my table too. At first I thought: fine, I'm only dealing with a single application, so I'll just add such a column and give it a default value. Then I realised that the ApplicationId is a GUID, so it'd be a pain to do this. Not hard exactly, but until I roll out my DB I can't predict what the GUID is going to be. I feel like I'm missing something, or going about things the wrong way. What am I supposed to do?
Initially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?
View 4 RepliesI'd like to connect my Oracle Server Database 11g (in another machine) with the default project of Microsoft Visual Web Developer 2010.
I did :
Start A new Project : ASP.NET Web Application
The design fit very well with my simple needs, so i've modified the css file and some apsx for my project, and i'm trying tu use Oracle instead of SQL-Server
I've downladed ODTwithODAC112012 from the Oracle website, and installed it. First problem i thought that it will recognize Visual Web Developer as a Visual Studio solution, but it doesn't ! so in the Project/Add Class i haven't Oracle.DataAccess
In fact i just want to use the authentification from Oracle to log my user, using my tnsnames.
What i should i do to get it, or do i need to use another way ?
In the Web.config file there's a lots of definition like "provider", that i don't know how to use !! is there a typical way to do with oracle ?
I have a excel sheet and I want to make the 2nd row my header column and read the data from the 3rd row, considering 2nd row is the Column name.
View 1 RepliesI am having the error stated above. The stack trace is as follows:

I have checked all forums and posts regarding this error. They mention that there are 2 versions of Oracle.DataAccess.Client on the server, I only have 1 version. This runs on VS2010, but when I publish the website the error above shows up. I checked my Oracle connection from the installer and connection test passed. I tried uninstalling Oracle and reinstall, but still the same. The query above I tried changing to 'select region_code, reg_rom, ...', still the same error..
I just downloaded and installed the most recent MySQL .net connector, 6.3.6 and it connects to the DB just fine. My problem is with the web.config settings I have set for it. It seems that theMinRequiredNonAlphanumericCharacters property is hard coded to '1'.I've changed this to 0, 5, or any other number. I even setup a web page to just display the properties of the provider. If I change the values in the web.config, the values update. It seems that MinRequiredNonAlphanumericCharacters won't change.
[Code]....
Again, the DB connection works just fine, reason I did not post the connection string. The min password length at 44 was just for testing.
[Code]....
Of the three I only tested, only MinRequiredNonAlphanumericCharacters stays at '1' no matter what I change it to in the web.config. I even changed it to 'abcd' and received no .NET runtime errors. Me thinks it is hard coded some where or I'm not using the right property name in the web.config. I copied the web.config value straight from the example in the documentation that came with the MySQL .net connector.
