Hi,
I created a method in the webservice which will take productid as input parameter and return the product number, productname, and vendor account number and vendor name. I was able to run the web service successfully. And also created the assemblies and sp using these assembly.
At the final execution i am getting some security exception
The following is the exception I am getting….
CREATE PROCEDURE GetProductVendorDetails(@.ProductID int)
AS
EXTERNAL NAME GetProductVendorAssembly.StoredProcedures.CallWebService
GO
EXECUTE GetProductVendorDetails 2
Msg 6522, Level 16, State 1, Procedure GetProductVendorDetails, Line 0

My Web Service Method ….
[WebMethod]
private void GetProductDetails(int ProductID)
{
// String ProductVendorDetail="";
//Set the connection string for the database
string connectionstring = "Server=PC013584;Database=AdventureWorks;User=Raj;Password=password";
//Create Connection and open it
SqlConnection conn = new SqlConnection(connectionstring);
conn.Open();
//Create the command object
SqlCommand comm = new SqlCommand();
comm.Connection = conn;
comm.CommandText = "SELECT P.ProductID as ProductID,P.Name as ProductName,P.ProductNumber as ProductNumber,V.AccountNumber as VendorAccountNumber,V.Name VendorName"
+ " FROM Production.Product P "
+ " INNER JOIN Purchasing.ProductVendor PV ON (PV.ProductID = P.ProductID) "
+ " INNER JOIN Purchasing.Vendor V ON(V.VendorID = PV.VendorID) "
+ " WHERE P.ProductID =" + ProductID.ToString();
SqlDataReader thisReader = comm.ExecuteReader();
while (thisReader.Read())
{
//Console.WriteLine(myReader["Column1"].ToString());
//Console.WriteLine(myReader["Column2"].ToString());
pvinfo.ProductID = Int32.Parse(thisReader["ProductID"].ToString());
pvinfo.ProductName = thisReader["ProductName"].ToString();
pvinfo.ProductNumber = thisReader["ProductNumber"].ToString();
pvinfo.VendorAccountNumber = thisReader["VendorAccountNumber"].ToString();
pvinfo.VendorName = thisReader["VendorName"].ToString(); ;
}
thisReader.Close();
conn.Close();
}
[WebMethod]
public ProductVendorInfo GetProductVendorDetails(int ProductID)
{
GetProductDetails(ProductID);
ProductVendorInfo pvi = new ProductVendorInfo();
pvi.ProductID = pvinfo.ProductID;
pvi.ProductName = pvinfo.ProductName;
pvi.ProductNumber = pvinfo.ProductNumber;
pvi.VendorAccountNumber = pvinfo.VendorAccountNumber;
pvi.VendorName = pvinfo.VendorName;
return pvi;
}
My CLR Procedure code is as follows….
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using CLRWebServiceProject.LocalWebService;
public partial class StoredProcedures
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void CallWebService(int ProductID)
{
// Put your code here
ProductVendorInfoService S = new ProductVendorInfoService();
S.UseDefaultCredentials = true;
ProductVendorInfo pvi = new ProductVendorInfo();
pvi = S.GetProductVendorDetails(ProductID);
String PN = pvi.ProductName;
String PNum = pvi.ProductNumber;
String VANum = pvi.VendorAccountNumber;
String VN = pvi.VendorName;
using (SqlConnection cn = new SqlConnection("context connection=true"))
{
string query = "INSERT INTO dbo.ProductVendorDetail(ProdcutID,ProductName,ProductNumber,VendorAcccountNumber,VendorName)"
+" VALUES ('"+ProductID+","+PN+","+PNum+","+VANum+","+VN+"')";
using (SqlCommand insertCommand = new SqlCommand(query, cn))
{
cn.Open();
insertCommand.ExecuteNonQuery();
cn.Close();
}
}
}
};
Can you help what exactly this error relates/ pointing to? Am i doing any mistake while creating the procedure?
Thanks
Raj
Is your sgen:ed assembly strongly named, by any chance? If so, sign your clr assembly with the same key.
Actually, try and sign your sqlclr assmembly anyway.

It is already have strong key name...
I added "Integrated Security=true" in the connection string then the security exception was solved..
Still i am getting the exception:
Msg 6522, Level 16, State 1, Procedure GetProductVendorDetails, Line 0
A .NET Framework error occurred during execution of user-defined routine or aggregate "GetProductVendorDetails":
System.InvalidCastException: Unable to cast object of type 'System.Data.SqlTypes.SqlInt32' to type 'System.IConvertible'.

using (SqlCommand insertCommand = new SqlCommand(query, cn))
{
cn.Open();
insertCommand.ExecuteNonQuery();
cn.Close();
}
}
}
};
the exeception seems to be related to conversion..... :-(
|||In your call to Convert.ToInt32 you send in ProductId, which is of type SqlInt32. ToInt32 does not take SqlInt32. I don't really understand why you call ToInt32 in this scenario. Why don't you just do:
int ProdId = ProductId.Value;
All SqlTypes do have a Value property which gives you back the underlying CLR type. Just make sure that ProductId is not NULL before you do this.

hi,
The following is the CLR code and i was able to compile and create the sp from the assembly
CREATE PROCEDURE GetProductSuppliersDetails(@.Product int)
AS
EXTERNAL NAME GetProductSupplierAssembly.StoredProcedures.GetSuppliers
GO
and on execution
EXECUTE GetProductSuppliersDetails 1
i am getting the following exception
Msg 6522, Level 16, State 1, Procedure GetProductSuppliersDetails, Line 0
A .NET Framework error occurred during execution of user-defined routine or aggregate "GetProductSuppliersDetails":
System.NullReferenceException: Object reference not set to an instance of an object.
System.NullReferenceException:
at StoredProcedures.GetSuppliers(Int32 ProductID)
.
Is there any thing wrong in the code ....
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using TestProject.ProductSupplier;
public partial class StoredProcedures
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void GetSuppliers(int ProductID)
{
// Put your code here
Service S = new Service();
S.UseDefaultCredentials = true;
DataSet ds = new DataSet();
ds = S.GetProductSupplier(ProductID);
DataTable dt = new DataTable();
dt = ds.Tables["ProductSuppliers"];
using (SqlConnection cn = new SqlConnection("context connection=true"))
{
foreach (DataRow row in dt.Rows)
{
string query = "INSERT INTO dbo.ProductSupplier(ProdcutID,ProductName,CompanyName,ContactName,ContactTitle,Address,City)"
+ " VALUES ('";
int cCount = 0;
foreach (DataColumn col in dt.Columns)
{
if (dt.Columns.Count < cCount)
{
query += row[col.ColumnName].ToString() + ",";
}
else
{
query += row[col.ColumnName].ToString() + "')";
}
cCount++;
}
using (SqlCommand insertCommand = new SqlCommand(query, cn))
{
cn.Open();
// Console.WriteLine(row[col]);
insertCommand.ExecuteNonQuery();
cn.Close();
}
}
};
Thanks in Advance...
|||Well, that error message is really hard to interpret, can't you debug into the CLR method and see where the exception happens? Alternatively, you could refactor the code into a console application and just check and see what happens.
I would look closer at where you assign the data table to a table from the dataset, are you sure there exists a table in the DataSet called "ProductSuppliers"?

Issue solved . I got it corrected.
public static void GetSuppliers(int ProductID)
{
// Put your code here
Service objService = new Service();
objService.UseDefaultCredentials = true;
DataSet dsProdSupply = objService.GetProductSupplier(ProductID);
//using (SqlConnection cn = new SqlConnection("Server=PC013584;Database=NorthWing;User=Raj;Password=password;Integrated Security=SSPI"))
using (SqlConnection cn = new SqlConnection("context connection=true"))
{
if (dsProdSupply != null)
{
if (dsProdSupply.Tables[0] != null)
{
foreach (DataRow drProdSupply in dsProdSupply.Tables[0].Rows)
{
string query = "INSERT INTO dbo.ProductSupplier(ProductName,CompanyName,ContactName,ContactTitle,Address,City)"
+ " VALUES ('" + drProdSupply["ProductName"].ToString() + "','" + drProdSupply["CompanyName"].ToString() + "','" + drProdSupply["ContactName"].ToString() + "','" + drProdSupply["ContactTitle"].ToString() + "','" + drProdSupply["Address"].ToString() + "','" + drProdSupply["City"].ToString() + "')";
/*
int cCount = 0;
foreach (DataColumn dcProdSupply in dsProdSupply.Tables[0].Columns)
{
if (dsProdSupply.Tables[0].Columns.Count < cCount)
{
query += "'" + drProdSupply[dcProdSupply.ColumnName].ToString() + ",";
}
else
{
query += "'" + drProdSupply[dcProdSupply.ColumnName].ToString() + "')";
}
cCount++;
}* */
using (SqlCommand insertCommand = new SqlCommand(query, cn))
{
cn.Open();
// Console.WriteLine(row[col]);
insertCommand.ExecuteNonQuery();
cn.Close();
}
}
}
}
}
Thanks To Karthik Who helped me in correcting the issue...
