CLR WebService Access

I need to access a billing webservice from SQL. I createde a new c# class project and made a web refrence to the web service "ProdBilling".

Here is the code of my assembly

using System.Data;
using Microsoft.SqlServer.Server;
using System.Data.SqlTypes;
namespace PaymentProc
{
public class PaymentProc
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void ChargeCard(int account, int amount)
{
string Response;
ProdBilling.Service serv = new ProdBilling.Service();
Response = serv.ChargeCard(account, amount);
SqlContext.Pipe.Send(Response);
}
}
}

I then ran WSDL

wsdl /o:PaymentProc.cs /n:PaymentProc http://ProdWeb1/PaymentProc/PaymentProc.asmx

Then compliled

csc /target:library PaymentProc.cs

and added the assembly
CREATE ASSEMBLY PaymentProc from 'D:\ProdCode\PaymentProc.dll' WITH
PERMISSION_SET = UNSAFE

I cannot figure out how to refrence the chargecard method

I have tried

CREATE PROCEDURE PaymentProc
@Account int,
@Amount int
AS
EXTERNAL NAME PaymentProc.[PaymentProc.PaymentProc].ChargeCard

It seems wsdl.exe put all this serialization code

namespace PaymentProc {
using System.Diagnostics;
using System.Web.Services;
using System.ComponentModel;
using System.Web.Services.Protocols;
using System;
using System.Xml.Serialization;

/// <remarks>
[System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42")]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Web.Services.WebServiceBindingAttribute(Name="ServiceSoap", Namespace="http://ProdWeb1/PaymentProc")]
public partial class PaymentProc : System.Web.Services.Protocols.SoapHttpClientProtocol {

private System.Threading.SendOrPostCallback ChargeCardOperationCompleted;

/// <remarks>
public PaymentProc()
{
this.Url = "http://ProdWeb1/PaymentProc/PaymentProc.asmx";
}

/// <remarks>
public event ChargeCardCompletedEventHandler ChargeCardCompleted;

/// <remarks>
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://ProdWeb1/PaymentProc/ChargeCard", RequestNamespace="http://ProdWeb1/PaymentProc", ResponseNamespace="http://ProdWeb1/PaymentProc", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
public string ChargeCard(int account, int amount) {
object[] results = this.Invoke("ChargeCard", new object[] {
account,
amount});
return ((string)(results[0]));
}
.................

When I run

CREATE PROCEDURE PaymentProc
@Account int,
@Amount int
AS
EXTERNAL NAME PaymentProc.[PaymentProc.PaymentProc].ChargeCard

Method, property or field 'ChargeCard' of class 'PaymentProc.PaymentProc' in assembly 'PaymentProc' is not static.

Any ideas?

Unexpected existing transaction --> error

Hi,

My code worked fine before i placed "SqlTransaction" command in my code. After placing "SqlTransaction" command in my code it is showing "Unexpected existing transaction." Please tell me where I am going wrong.

My Code:
protected void Page_Load(object sender, EventArgs e)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["Mfund_String"].ConnectionString))
{
con.Open();
using (SqlConnection destinationConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["Mfund_String"].ConnectionString))
{
destinationConnection.Open();
using (SqlTransaction transaction = destinationConnection.BeginTransaction())
{
SqlCommand DelCmd = new SqlCommand("delete from mfund_data", con);
DelCmd.ExecuteNonQuery();
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(destinationConnection))
{
bulkCopy.DestinationTableName = "mfund_data";
try
{
bulkCopy.WriteToServer(CreateDataTableFromFile());
transaction.Commit();
}
catch (Exception ex)
{
transaction.Rollback();
Response.Write(ex.Message);
}
}
}
destinationConnection.Close();
}
con.Close();
}
}

Regards,
Jagadeesh

Hi Jagadeesh

According to this[^], you need to pass your SqlTransaction object into the SqlBulkCopy constructor.

Thank you Andy,

Your link helped me a lot in fixing the issue. Actually while googling in the morning i came accross this page but I ignored the crytical part of it.

By going through the same page aging now @ mid night helped me very much Smile | :)

The mistake was here
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(destinationConnection, SqlBulkCopyOptions.KeepIdentity, transaction))

Thanks again for support,
I am Smile | :)

how to generate autonumber in ceratin sequence

i have a table in sqlserver2005 named emp.

where the coloumns of the emp table are as follows.
empid int,
empname varchar(20),
empaddrs varchar(20),
empDOB dateandtime,
empsex char(1),

i want to genertae empid as autogenertaed sequencitial number.
where the format of the auto genertaed number for empid will be -yyyy-sex-nnnn

where 1st for places are the year of his dob.
5th place would be the first letter of his/her sex
and last 4 place that is from 6th to 10th would be number (means 0001 ,0002)

example of auto generated number are-1983M001,1985F0002,2005M0003...and so on..
can u tel me how i wil do it in SQLSERVER2005.

(i know only how to generate auto num.by setting its identity to true.but dont know what to write in the formula filed so that i can genrate the above type of auto generated number)

Hi,

I need some help. I have a DB layout like this:

Table FirstNames
Table LastNames
Table Users

Table firstnames and Lastnames are linked to Table Users. What I need to do is the following. If someone adds his/her FirstName and LastName the ID from those tables gets inserted into the Users. The ID's are auto incremented.

Table FirstNames
1 Fritz

Table LastNames
1 Blignaut

Table Users
1
1

If someone adds his name and it's the same as Fritz than the ID "1" should be added to the Users Table.

Thanks!

After you insert values in Table FirstNames and LastNames then insert max id into users table.

Example

declare @FNID as int<br />
set @FNID = (select max(ID) from firstnames)<br />
declare @LID as int<br />
set @LNID = (select max(ID) from lastnames)<br />
<br />
Insert into users (firstnameID,LastNameID) values (@FNID,@LNID)

or use triggers

One way to do this would be:

DECLARE @FID INT
DECLARE @LID INT

SET NOCOUNT ON

SELECT @FID = [ID] FROM FirstNames WHERE FirstName = 'Fritz'

IF @FID IS NULL
BEGIN
  INSERT INTO FirstNames(FirstName) VALUES ('Fritz')
  SET @FID = Scope_Identity()
END

SELECT @LID = [ID] FROM LastNames WHERE LastName = 'Blignaut'

IF @LID IS NULL
BEGIN
  INSERT INTO LastNames(LastName) VALUES ('Blignaut')
  SET @LID = Scope_Identity()
END

INSERT INTO Users VALUES (@FID, @LID)

Are you sure that you really want to normalize down to this level? You are going to be doing an awful lot of looking up on information which is going to be wasteful in system processing terms.

Map one table to another in MSSQL

12-Aug-07 11:25

Hi all,

I have two ASP.NET modules that have been built at different times that I want to use together. there are only 4 tables that need to be merged, but both modules use stored procedures and Crystal reports extensively - so I am looking as to whether it is possible in MSSQL 2005 to map or alias the fields in one table to another, and so avoid a rather painful refactoring task. I have listed the tables and the corresponding fields below for greater clarity - the order and orderItems tables are the one's I need to keep.

orders(table) ==> cart(table)
OrderID(int PK identity) ==> CartID(int PK identity)
EntryDate(DateTime) ==> SaleDate(DateTime)
userID(uniqueidentifier) ==> CustomerName(varchar)
PartnerID(int) ==> PartnerID(int)
TransactionID(varchar) ==> ReceiptNo(varchar)
(no corresponding field) ==> CustomerEmail(varchar)

orderItems(table) ==> CartItem(table)
ItemID(int PK identity) ==> CartItemID(int PK identity)
OrderID(int) ==> CartID(int)
ProductID(int) ==> ProductID(int)
SellPrice(money) ==> SalePrice(money)

Many thanks in advance,
Nigel

Thanks for the reply Colin,

Must admit a limited understanding of table views - so I am not sure.

If I used a view, wouldn't I still have to refactor all the stored procedures and reports that use the cart and cartitems tables to use the view instead??

If I have to do that I am still in the same predicament.

Or is it possible to create a table view with the exact name of the original table (deleting the tables of course) and the SP's and reports will still pick up the data?

Cheers,
Nigel

If you are renaming the original tables and create views with the original table names then it should work. You may have to recompile the stored procedures to get it to pick up the changes.

thanks Colin - the views worked a charm!!

Still had some tidy up work as one module was built in the US and the other here in Australia - so the date formats were different, but otherwise a simple solution to what was potentially a nightmare.

Oh the joys of contract programming... Laugh | :laugh:
