XML Data Type & Namespace Problem
I have a problem with adding a namespace declaration to my XML query. As soon as I add the namespace declaration to the final XQuery most of my nodes disappear from the document. I've got a simplified version of it here so people can run it. If I remove the declare clause (in red) it works and you see all the nodes but then I don't have the namespace. So it seems to be that the subquery (in {}) isn't recognising the namespace declaration? declare @Tmp table (nodeValue int) insert into @Tmp (nodeValue) values (1) insert into @Tmp (nodeValue) values (2) insert into @Tmp (nodeValue) values (3) declare @x xml set @x = ( select nodeValue from @Tmp for xml path('node'), root('root'), type ) select @x.query('declare default element namespace "http://www.eqos.com/collaborator/data/"; <someOtherRoot> { for $node in /root/node return <proj class="something" key="{ data($node/nodeValue) }" /> } </someOtherRoot> ')

Why Do I Need Microsoft.SqlServer.Dts.Runtime.Wrapper Namespace
Hi, It states pretty clearly in the documentation for the Microsoft.SqlServer.Dts.Runtime.Wrapper namespace that "This assembly is a Primary Interop Assembly (PIA) for the namespace Microsoft.SqlServer.Dts.Runtime, which is the assembly Microsoft.SqlServer.ManagedDTS (in microsoft.sqlserver.manageddts.dll). The classes in this namespace should not be instantiated. Instead, use the classes found in the Microsoft.SqlServer.Dts.Runtime. " And yet as I have found out earlier today and talked about here, sometimes it is absolutely necassary to use Microsoft.SqlServer.Dts.Runtime.Wrapper. Why is this? Why is there no class in Microsoft.SqlServer.Dts.Runtime that allows me to access the specific connection managers rather than using the generic ConnectionManager class? -Jamie

Problem Sending 32KB Message Using ServiceBrokerInterface Example From Microsoft.Samples.SqlServer Namespace.
I have been using the ServiceBrokerInterface example for a project of mine and so far it has been very successfull. However , I recently attempted to use it to send a large-ish message (32K xml file from MS Word) to SQL. The message is recieved but the Body member of the message is null when I try to retrieve the data from within my stored procedure CLR method. The only differences I can see between the message that does not work and those that do are that the one that doesn't is large and it is XML data that I read from a .xml file produced by MS Word as opposed to internally generated strings in the other working messages. Does anybody have any suggestions as to why the body of the message is not being sent in this case? Is there something about the example code that precludes sending this type of message? This is the code that sends the message (extracted from Conversation.cs in ServiceBrokerExample) string query = "SEND ON CONVERSATION @ch MESSAGE TYPE @mt "; param = cmd.Parameters.Add("@ch", SqlDbType.UniqueIdentifier); param.Value = m_handle; param = cmd.Parameters.Add("@mt", SqlDbType.NVarChar, 255); param.Value = message.Type; if (message.Body != null) { query += " (@msg)"; param = cmd.Parameters.Add("@msg", SqlDbType.VarBinary); param.Value = new SqlBytes(message.Body); param.Size = -1; } cmd.CommandText = query; cmd.ExecuteNonQuery(); This is the code that reads the message from the SQL queue (extracted from Message.cs in ServiceBrokerExample) m_reader = reader; m_convGroupId = reader.GetGuid(0); m_conv = new Conversation(service, reader.GetGuid(1)); m_sequenceNumber = reader.GetInt64(2); m_serviceName = reader.GetString(3); m_contractName = reader.GetString(4); m_type = reader.GetString(5); m_validation = reader.GetString(6); if (!reader.IsDBNull(7)) { SqlBytes sb = reader.GetSqlBytes(7); Body = sb.Stream; } else Body = null; This is the MESSAGE TYPE used by this message. CREATE MESSAGE TYPE CreateReport_Command VALIDATION = None; Here is the code where msgReceived.Body == null in the SQL CLR method invoked by this message. [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Design", "CA1062:ValidateArgumentsOfPublicMethods"), System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Performance", "CA1822:MarkMembersAsStatic"), BrokerMethod("AssessmentContract", "CreateReport_Command")] public void CreateReport_Command( Message msgReceived, SqlConnection connection, SqlTransaction transaction) { StreamReader reader = null; try { reader = new StreamReader(msgReceived.Body); And finally here is the code snippet that creates the stream that gets loaded into the message to be sent. if (Report != null && ReportName != null) { MemoryStream ReportBody = new MemoryStream(); if (ReportID == null) { ReportID = Guid.NewGuid().ToString(); } ReportBody.Write(Encoding.ASCII.GetBytes(ReportID), 0, ReportID.Length); ReportBody.Write(Encoding.ASCII.GetBytes("|".ToCharArray()), 0, 1); ReportBody.Write(Encoding.ASCII.GetBytes(ReportName), 0, ReportName.Length); ReportBody.Write(Encoding.ASCII.GetBytes("|".ToCharArray()), 0, 1); ReportBody.Write(Encoding.ASCII.GetBytes(Report), 0, Report.Length); Microsoft.Samples.SqlServer.Message request = new Microsoft.Samples.SqlServer.Message("CreateAssessmentReport_Command", ReportBody); // Send the message to the service dialog.Send(request, conn, tran);

Where's The Namespace?
I'm trying to write my first sql server compact edition program. When I try to add a SqlCeConnection object to my .cs file, I need to add the namespace "using" reference. the online docs say it's System.Data.SqlServerCe, but my IDE won't find it. I've tried adding the reference, but neither System.Data.SqlServerCe nor system.data.sqlserverce.dll is on the .NET list. Where do I go from here?

The SQL Namespace Has Already Been Initialized.
I am trying to build a SQL Server 2000 (sp3) admin app in VB.NET that gives the users targeted access to EM functions without having to search through EM. At any rate, I cannot seem to re-initialize the SQL namespace, even after setting it to nothing (I want to enable a user to do work with one server, pop into another, etc). Here is a sample of what I am doing, stripped to its essentials. This code fails with the error in the subject line. Thanks in advance. Dim NS As New SQLNS.SQLNamespace, Str as String Str = "Server=SQLTEST;Trusted_Connection=Yes;" NS.Initialize("Application; ", SQLNS.SQLNSRootType.SQLNSRootType_Server, _ Str, Handle.ToInt32) NS = Nothing NS = New SQLNS.SQLNamespace Str = "Server=SQLPROXY;Trusted_Connection=Yes;" NS.Initialize("Application; ", SQLNS.SQLNSRootType.SQLNSRootType_Server, _ Str, Handle.ToInt32) NS = Nothing

Can You Rename A Namespace?
I recently restored an entire database hosted on a remote server onto my local PC. These are tables I created for an ASP.NET project I'm working on. Unfortunately, the tables are restored with a different namespace (I think that's what it's called). So, dbo.Authors restored as dbo19738468.Authors. The 19738468 is the customer number that was assigned to me by my Web host, where I backed up the data I restored. Is there anyway to rename the dbo19738468 to simply dbo?

Change Table From Namespace
I have a table like this : dbo.Table, and I recently create a namespace, and that table belongs there. So I want the table to be created on the new namespace, Namespace.Table, which is not big deal because I can script the table as a Create, and changes the [dbo].[table] to [Namespace].[Table]. But I need to import all the rows already on the old table. How can I achieve that? Thanks

SP2 XmlRendering Bug? Unused XML Namespace Inserted
Background: After upgrading to SP2 for our ReportServer boxes, we began noticing discrepancies with our reports that were exported to XML (using the "Microsoft.ReportingServices.XmlRendering.dll") that were not present in SP1. A discrepancy of particular consequence was the insertion of a new XML namespace in the root element: xmlns: p1="http://www.w3.org/2001/XMLSchema-instance" ^ (added a space before "p1" to avoid an emoticon) Now, it would be one thing is something actually used that "p1" prefix later in the XML, but that is not that case! The only thing that uses that "p1" namespace is an attribute that was automatically inserted at the root element level (p1: schemaLocation="..."), which also seems unimportant. Nonetheless, this has caused us unexpected XPath query issues as we were not acknowledging the new namespace in our .NET code. Questions: 1. Was this done for a reason, such as complying with new W3C standards? 2. As this is a breaking change for XPaths without a proper NamespaceManager, was this difference noted in any release documentation or white papers? 3. Is there any way to configure RS2005 SP2 such that unused namespaces such as this one are not inserted upon XmlRender? Please let me know. Thank you! Sincerely, James Greene

Setup Failing Due To Security Issue With WMI Namespace
I'm installing SQL Server Express SP1 on a new Windows XP Pro SP2 laptop that is part of a corporate network. The last item in the Setup Progress dialog box says: Workstation Components, Books Online and Development Tools....Setup failed. Refer to log file. C:Program FilesMicrosoft SQL Server90Setup BootstrapLOGSummary.txt looks fine except for the last few lines: -------------------------------------------------------------------------------- Machine : ROVER Product : Microsoft SQL Server 2005 Tools Product Version : 9.1.2047.00 Install : Failed Log File : c:Program FilesMicrosoft SQL Server90Setup BootstrapLOGFilesSQLSetup0004_ROVER_Tools.log Last Action : InstallFinalize Error String : SQL Server Setup failed to modify security permissions on WMI namespace \. ootMicrosoftSqlServerComputerManagement. To proceed, verify that the account and domain running SQL Server Setup exist, that the account running SQL Server Setup has administrator privileges, and that the WMI namespace exists on the destination drive. Error Number : 29516 Is this a common error when installing on a PC that is part of a corporate network? I didn't dig too far into SQLSetup0004_ROVER_Tools.log; however, it contains a few references to "SOFTWARE RESTRICTION POLICY". Other than this error, SQL Server Express seems to be working ok. Is this anything to be concerned about?

I created a .net console application within which I connect to a sql server (not local) as follows, string conn_str = "Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=QuantEquitySql;Data Source=server name"; SqlConnection conn = new SqlConnection(conn_str); conn.Open(); . Everything works fine when I run it from my computer. When I try to run it from a network share I get the following error, Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I am using Visual Studio 2005 and .Net framwork v2.0.50727. Does anybody know a fix to this problem? Thanks

Unable To Cast Object Of Type 'System.DBNull' To Type 'System.Byte[]'.
Hi, I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ? Thanks a lot in advance.

System.Data.SqlClient.SqlException: SQL Server Does Not Exist Or Access Denied.
Hi all Please help me. I have an asp.net 1.1 (vb.net) application which accesses data from a sql server 2000. I published this application on http://test.autenmas.co.za and the database I access is on 196.23.156.196. I am getting this error message when I run the application from this site: System.Data.SqlClient.SqlException: SQL Server does not exist or access denied. But it's working fine on my local, development machine. I am using the following connection string in my connections: "Data source=196.23.56.193; Initial Catalog=Autenmas; User Id=xxxx; password=yyyy" Is there anything wrong with my code, is there anything that must be done on the web/database server or any other configurations for that matter, what really is the problem?????? Thanks in advance.

Cannot Pass Params (data Type System.guid) To Subreport?
Hello experts, I am trying to create a report including a subreport in VS.2003 Reporting services. The subreport itself runs properly, if I give it a parameter, but when I try to run the main (parent) report, I get the obvious message Subreport could not be shown. The output windows returns a message: The value expression used in textbox €˜AccountID€™ returned a data type that is not valid. The AccountID field is a system.guid. I tried to "cast" it as a text, but I got another error message that the system.guid cannot be explicitly converted. Does anyone know how to get around this? Thank you very much. Ravie.
