Data Access :: MS Access ADODB Connection To Stored Procedure - Cannot Retrieve Data

Sep 22, 2015

I'm trying to re-write my database to de-couple the interface (MS Access) from the SQL Backend.  As a result, I'm going to write a number of Stored Procedures to replace the MS Access code.  My first attempt worked on a small sample, however, trying to move this on to a real table hasn't worked (I've amended the SP and code to try and get it to work on 2 fields, rather than the full 20 plus).It works in SQL Management console (supply a Client ID, it returns all the client details), but does not return anything (recordset closed) when trying to access via VBA code.The Stored procedure is:-

USE [VMSProd]
GO
/****** Object: StoredProcedure [Clients].[vms_Get_Specified_Client] Script Date: 22/09/2015 16:29:59 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

Difference Between Select Query And SelectCommand In Data Adapters

May 27, 2008

 

Can any one tell me the difference between Select Query and
SelectCommand in data adapters?

 

Using SelectCommand:

 

string selectSQL = "SELECT CustomerID, CompanyName FROM Customers WHERE Country = @Country AND City = @City"; SqlConnection nwindConn = new SqlConnection("Data Source=localhost;Integrated Security=SSPI;Initial Catalog=northwind");SqlDataAdapter custDA = new SqlDataAdapter();           SqlCommand selectCMD = new SqlCommand(selectSQL, nwindConn);custDA.SelectCommand = selectCMD; // Add parameters and set values.selectCMD.Parameters.Add("@Country", SqlDbType.NVarChar, 15).Value = "UK";selectCMD.Parameters.Add("@City", SqlDbType.NVarChar, 15).Value = "London"; DataSet custDS = new DataSet();custDA.Fill(custDS, "Customers");  Using Select Query: 

SqlDataAdapter
da = new SqlDataAdapter("select P_UID,P_EMIAL,P_NAME from p_users where p_email=@p_email
and p_pwd=@p_pwd", con);

            da.SelectCommand.Parameters.Add("@p_email", SqlDbType.VarChar, 50).Value
= etxt1.Text;

            da.SelectCommand.Parameters.Add("@p_pwd", SqlDbType.VarChar, 50).Value = pwdtex.Text;   Can you plz tell vat is the need for giving custDA.SelectCommand and adding parameters to that command instead of  directly giving Select Query in Data Adapter?  Similarly  Update Command: custDA.UpdateCommand.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID") custDA.UpdateCommand.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName")Dim myParm As SqlParameter = custDA.UpdateCommand.Parameters.Add("@OldCustomerID", _ SqlDbType.NChar, 5, "CustomerID")myParm.SourceVersion = DataRowVersion.Original[C#]custDA.UpdateCommand.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID"); custDA.UpdateCommand.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName"); SqlParameter myParm = custDA.UpdateCommand.Parameters.Add("@OldCustomerID", SqlDbType.NChar, 5, "CustomerID");myParm.SourceVersion = DataRowVersion.Original; instead of above process, y cant v do above method in below procedure? 

private void UpdateStudent(int
RollNo, string SName, string
Course, DateTime Doj, Decimal
FeePaid)

    {

        SqlConnection
conn = new SqlConnection("Data Source=UMASHANKAR\SQLSERVER2005;Initial
Catalog=employee;Persist Security Info=True;User ID=sa;pwd=sa1 ");

 

        SqlCommand
cmd = new SqlCommand("UPDATE Student SET SName='" + SName + "',Course='" + Course + "',Doj='" + Doj + "',FeePaid='" + FeePaid + "'
WHERE RollNo=" + RollNo, conn);

 

        try

        {

            if
(conn.State == ConnectionState.Closed)
conn.Open();

            cmd.ExecuteNonQuery();

        }

        catch {
}

        finally

        {

            cmd.Dispose();

            conn.Close();

            conn.Dispose();

        }

    }

 

PLZ TELL ME
THE DIFFERENCE OR ANY ADVANTAGES OF UPDATECOMMAND PROCESS AND QUERY METHOD

  IN this way I want difference OR ANY ADVANTAGES for InsertCommand, DeleteCommand also

SELECT Data: Stored Procedures Or View?

May 10, 2007

Hi, I'm developing a fresh SQL DB which is result of a deep analysis of an old Access DB. THe thing is, this old one had very complex consultations to the Access tables, and some consultations were using another consultations as way to select some specific data. THe ideia in SQL is to avoid that too, however, there are some data that may serve exactly the same to some bigger stored procedures. This way, I have three options I guess: 1. Create every stored procedure making select queries directly to the table and it's done!2. Create auxiliary stored procedures which will select the redundant data, and when it is needed, another stored procedures call this one and use its returned data. (is this possible anyway?).3. I create a view to this redundant data, and the greater depth stored procedures access this data of the view when needed. I've heard, however, that a select to a view is slower than directly to the table, once the view adds an extra query to the process.. What is your guess on this issue of mine?I'm almost sure that option 1 is the best, however, I'd love to hear from you guys your opinion on this. The greater issue above this all is just one - performance. Thanks a lot!

Data Warehousing :: Run Stored Procedures On PDW Via SSIS

Aug 4, 2015

How do you run a stored procedure on PDW via SSIS? I've tried Execute SQL Task and Execute T-SQL Task but in both cases the task will run and complete almost immediately. Task shows success, no errors, but nothing happens in PDW.   PDW admin console does not even register the query. Procedures run fine manually from SQL Server Object Explorer connection.

Using Stored Procedures To Insert And Pull Data From Database

Mar 21, 2008

I have my database: "RequestTrack"
My table (with its columns): "Request"RequestKey (automatically generated)..and the Primary KeyEntryDate  (datetime)Summary (nvarchar)RequestStatusCodeKey (bigint)EntryUserID   (nvarchar)EntryUserEmail (nvarchar)I am wanting to create a basic web form where my user interface has 3 text boxes and a Submit button:
txtUserID.TexttxtEmailAddress.TexttxtRequestSummary.Text
**After I hit the submit button the information will then be inserted into the database. Also the RequestStatusCodeKey will be MANUALLY typed in so that will not require the user to add that. Please please please help ! I've been searching online for days and looking at various websites and still havent found anything. I've found somethings but they went into too much depth with too much information. I am just wanting to stay basic but w/o using SQLDataSource Controls. I would like to be able to store a lot of data. Thanks for your help!!!

Stored Procedures Or C# Code For My Purpose (Data Synchronisation)

Jul 4, 2005

Hi all,

I am in the position where I have to transfer data from an old database
schema to a new database schema. During the transfer process alot of
logic has to be performed so that the old data gets inserted into the
new tables and are efficiently done so that all foreign keys are
remained and newly created keys (as the new schema is Normalised alot
more) are correct.

Is it best if I perform all this logic in a Stored Procedure or in C# code (where the queries will also be run)?

Array Data Type In SQL Server Stored Procedures?

Aug 17, 2000

Is there any array data type in SQL Server 7.0. I am using VB 6.0 with ADO 2.1. I am populating a MSFlexGrid with values that I pass to SQL Server one at a time and insert into the database. What I would like to do is pass the entire contents of the Grid at once to a stored procedure and let SQL do the processing so my routine is not going back and forth to the client. I did not find any documentation on any array data types in SQL. What is my best approach to this problem?
Thanks,
Dan Collins

But I still have problems withe sql command. You have an example in your article ('dynamic sql 2'), showing how to do a sql SELECTION using a table name and a local variable. But the sql command only use a local variable of varchar type. I'm trying to do INSERT with local variables with different data types. For example:

I guess I could change all the columns in the table to data type of varchar. But are there any other way to solve this problem?

Many thanks.

Stored Procedures - Insert Data Gathered From Sele

Mar 28, 2008

Hi,

I am trying to write a stored procedure, which does a couple of things.

First thing is it looks up a persons Location based on an ID number, which is passed from an external Script. This will return four Values from a table.

I want to insert those four values into another table, along with another ID passed to the procedure from the same script.

My question is, what do I do to the script below to get the four values out of the first look up, into the insert?

The Field names returned from the SELECT are, AREA1, AREA2, AREA3, AREA4

Thanks

David


CREATE PROCEDURE UserAssign_Location

@UserID Int, @AreaID Int
AS
BEGIN
SET NOCOUNT ON;

SELECT * From Locations Where EntryID = @AreaID

INSERT INTO Members_Locations (UserID, Location1, Location2, Location3, Location4, Active)
VALUES (@UserID, 'AREA1', 'AREA2', 'AREA3', 'AREA4', 1)

END
GO

SQL Data Access With App's Exe Stored On A UNC Path?

Aug 29, 2006

Hello, This might be a simple thing, but I'm not able to find out the solution.

We have an application that accesses data from a SQL database. This works as long as the exe is located on the local drive of the user, however if the exe is stored on a unc path, we get the following execption thrown:

"System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

The action that failed was:
Demand
The type of the first permission that failed was:
System.Data.SqlClient.SqlClientPermission
The Zone of the assembly that failed was:
Intranet"

On our developer machines we have a control panel for .net 2.0 configuration and can get it to work by setting the intranet zone to full trust. However the users don't have this control panel. 2 questions:

a) Is there a way to get this control panel on the users station?

and

b) Is there a beter way to make this work?

Thanks, any help would be appreciated.

Using Return X In A Stored Procedure Doesn't Work With Table Adapters

Mar 9, 2007

Hi,

I was trying to create a simple SP that return a single value as follows:CREATE PROCEDURE IsListingSaved@MemberID INT,@ListingID INTASIF EXISTS (SELECT [Member_ID] FROM [Member_Listing_Link] WHERE [Member_ID] = @MemberID AND [Listing_ID] = @ListingID)    Return 1ELSE    Return 0GOWhen I try it out in the Tableadapter's preview table, I get the correct result (1, where the entries exist). However, in the BLL, I tried to get the value as:Dim intResult as IntegerintResult = CType(Adapter.IsListingSaved(intMemberID, intListingID), Integer). However, this always returns 0 (when it should be returning 1). P.S. Curiously, breakpoints skipped the VS generated code for the adapter. What could be the problem? Thanks,Wild Thing

Problem In Data Access Though SQL Server Stored Procedure

Apr 17, 2008

I have two database SOP and CRM. Both supports windows authentication and SOP suports sql authentication too. Now i have to write a SP in SOP database with identity impersonation (with superadmin authentication) which will do some work with this impersonated id on SOP database but needs to fetch some values from CRM with the current user account - not impersonated account.Lets clear... I want to show the orders generated by all users and in the display grid there is a column like "IsMyCustomer?" which will show the order is to a customer which i have access. In CRM (MS) if i select from FilteredCustomer view i will get the customersid of those under me. And if i left outer join with FilteredOrder view in SOP (with Super Admin windows credentials)  which returns orders by current user i will get the desired result.Now the problem is i can't sent two connection credentials to a SP. So what i want is to connect SOP with user's windows credentials (not with impersonation) and from the SP we will Select data with Admin's account. But i don't know is there any way to connect to a linked server with a different credentials. Like when i am selecting from CRM server it will use different credentials.Remember i am using SQL server 2000 and everything should be done through a single SP.I know i can do this easily with two different select from Data access layer. But i am looking for some performance effectinve way. My PM wants this idea to be implemented. I have no chice guys....

Data Access :: Management Studio To Access Data On Laptop?

Jun 30, 2015

I have a client who has SSMS installed on her laptop.  She is able to connect to the SQL server via SSMS in the office and query data on the server.

She needs to be out of site often and doesn't have internet access.  She asks if the data tables can be "backed up" or saved on her laptop, so she can look at them without worrying connecting to the server.  I am not sure if this can be achieved, as SSMS is built for accessing a server, not a desktop.  Myself never have this need.  If I really need it, I would go to Microsoft Access and create an ODBC connection to the datatables. But this client thinks that Microsoft Access is beneath her.

Restricting Access To Stored Procedures

Oct 5, 2005

I'm going through the SQLSecurity Checklist I found at sqlsecurity.com. One of the points it says to "Restrict to sysadmins-only access to stored procedures and extended stored procedures that you believe could pose a threat." It also lists a bunch of stored procs and extended stored procs that you should consider restricting to sysadmins only. I was wondering if someone could give me some pointers on how to do this? I would like to write a script that I could run on every sql server 2000 install that would do this. How could I ensure that every user does not have access except the sysadmins?

Thanks,
Chris

Can't Access Properties On Stored Procedures

Hi. I have set up an instance of SQL 2005 on my local computer. I use MS SQL Server Management Studio to login into my 2005 instance via Windows login. When I expand "Stored Procedures" under "Programmability" of the Database I want and go to a stored procedure and right click, I don't see the "properities" selection.

I know it's there because I can get to it on other instances but I can't get to it on my local instance. I added my windows user to my Logins and then to my database users but it didn't help.

Can anyone please tell me what I need to do so I can access the properties of the stored procedures?



Thanks
