Thanks in advance

I want to insert each comma separated value in a table column…my output look like this:

COLUMN
1
2
3
45
6
7
8

I created a dll (SqlWcfServiceLibrary1.dll) using .net frammework 2008. My code has a reference of another assemble (WcfServiceLibrary1.dll) also. I want to create assemble in sql and use that assemble in a procedure.

I am getting error that “Error while referencing external assembly“.

I am pasting all code that I used….

.cs page code –

namespace SqlWcfServiceLibrary1
{
public class SqlService1
{
void SendToSql(string message)
{
SqlMetaData[] table = new SqlMetaData[1];
table[0] = new SqlMetaData(“Message”, SqlDbType.VarChar, 1000);

SqlDataRecord row = new SqlDataRecord(table);
row.SetValue(0, message);

SqlPipe pipe = SqlContext.Pipe;
pipe.SendResultsStart(row);
pipe.SendResultsRow(row);
pipe.SendResultsEnd();
}

public static void GetMessage(SqlString name)
{
Assembly assembly = LoadAssembly(“D:\\OutCast\\WcfServiceLibrary1\\WcfServiceLibrary1\\bin\\Debug\\WcfServiceLibrary1.dll”, true);

Type type = LoadType(assembly, “WcfServiceLibrary1.Service1″, true);

String message = “”;
using (ServiceHost host = new ServiceHost(type))
{
host.Open();
IService1 service1 = InitChannel();
message = service1.GetMessage(name.ToString());
host.Close();
}
}

static IService1 InitChannel()
{
Uri address = new Uri(“net.tcp://localhost:8731/Design_Time_Addresses/WcfServiceLibrary1/Service1/”);

ChannelFactory<IService1> factory = new ChannelFactory<IService1>(new NetTcpBinding(), new EndpointAddress(address));
return factory.CreateChannel();
}

static Assembly LoadAssembly(String assemblyName, bool throwOnError)
{
Assembly assembly = null;

try { assembly = Assembly.LoadFrom(assemblyName); }
catch { }

if (assembly == null && throwOnError)
throw new Exception(“Hello Sujeet, Error while referencing external assembly.\r\n \r\nAssembly ‘” + assemblyName + “‘ doesn’t exist.”);

return assembly;
}

static Type LoadType(Assembly assembly, String typeName, bool throwOnError)
{
Type type = null;

try { type = assembly.GetType(typeName, false, true); }
catch { }

if (type == null && throwOnError)
throw new Exception(“Error while loading type.\r\n \r\nType ‘” + typeName + “‘ doesn’t exist.”);

return type;
}
}

[ServiceContract]
public interface IService1
{
[OperationContract]
string GetMessage(string name);
}
}

using above code I created a dll and using it in sql.

SQL Code –

– create assembly
CREATE ASSEMBLY SqlWcfServiceLibrary1 FROM
‘D:\OutCast\SqlWcfServiceLibrary1\SqlWcfServiceLibrary1\bin\Debug\SqlWcfServiceLibrary1.dll’
WITH PERMISSION_SET = EXTERNAL_ACCESS
GO

–create procedure
– external name is composed by CREATE PROCEDURE GetMessage ( @name nvarchar(max) )
AS EXTERNAL NAME SqlWcfServiceLibrary1.[SqlWcfServiceLibrary1.SqlService1].GetMessage

–Execute
exec GetMessage ‘Sujeet’

I am able to create assemble, procedure but when I am EXECUTING procedure, it is giving error…..

Msg 6522, Level 16, State 1, Procedure GetMessage, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate ‘GetMessage’:
System.Exception: Hello Sujeet, Error while referencing external assembly.

Assembly ‘D:\OutCast\WcfServiceLibrary1\WcfServiceLibrary1\bin\Debug\WcfServiceLibrary1.dll’ doesn’t exist.
System.Exception:
at SqlWcfServiceLibrary1.SqlService1.LoadAssembly(String assemblyName, Boolean throwOnError)
at SqlWcfServiceLibrary1.SqlService1.GetMessage(SqlString name)

Please provide me solution on this.

Thanks in advance.
