View 5 Replies View RelatedHi,
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?

Hello,
Where can I find the reference to Microsoft.SqlServer.Management.Smo in SQL Server 2005?
I currently have Microsoft SQL Server 2005, Microsoft SQL Native Client and Server VSS writer installed. (and ran the Service Pack 2 installer, but it doesn't want to update 'Database Services')
Thanks in advance,

View 2 Replies View RelatedI created a clr proc that gets the most recent file within a directory based on the creation time property, see code below.

Just wondering if someone could tell me why this is happening? I have the same namespaces that I have in the DAL in my BLL.Puzzled.
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
{

And finally here is the code snippet that creates the stream that gets loaded into the message to be sent.

{

I'm trying to write my first sql server compact edition program.

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?
I can't find the ReportingService's namespace... i see ReportingService inerhits from System.Web.Services.Protocols.SoapHttpClientProtoco but any code what i found its impossible to compile, i need the namespace...
View 3 Replies View RelatedI 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?

<Box>Blaff</Box>
<Door>Steal</Door>

I would like to remove the namespace - i.e.:

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?

SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = 186)
Can anybody tell me why this is?
And tell me a way to get the tableadapter working?

I have created a windows library control that accesses a local sql database
I tried the following strings for connecting
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"
I am not running the webpage in a virtual directory but in
C:Inetpubwwwrootusercontrol
and I have a simple index.html that tries to read from an sql db but throws
the error
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.
at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)
at System.Security.PermissionSet.Demand()
at System.Data.Common.DbConnectionOptions.DemandPermission()
at System.Data.SqlClient.SqlConnection.PermissionDemand()
at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,
etc etc
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:
Trusted
I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security
I think that a windows form connecting to a sql database running in a webpage should be simple
to configure what am I missing?
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
Hi,
I've written this code multiple times now. But for the first time i get an error at the line underlined. My procedure runs perfectly when i execute it through Sql Query analyzer.
plzz help.. Its urgent and am unable to find the reason for this error "A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in system.data.dll"
Thanks !SqlConnection conn = new SqlConnection(DbConnectionString);
conn.Open();
SqlCommand cmd = conn.CreateCommand();
cmd.CommandText = "dbo.rqryTradesPRR";
cmd.Parameters.Add("@COBDate",SqlDbType.DateTime).Value = "2002-10-31 00:00:00.000" ;
SqlDataReader reader = cmd.ExecuteReader();
while(reader.Read())
{
// have written something here
}
Thanks in advance !
hi i dont know how to do type casting.
this.Variables.ObjVariable this objVariables i have create in variable place below like this
Name:Variable datatype int32 values 0
Name: NumberofRowsdatatype int32 values 10000
Name: ObjVariable datatype Object
My code
public override void CreateNewOutputRows()
{
/*
Add rows by calling the AddRow method on the member variable named "<Output Name>Buffer".
For example, call MyOutputBuffer.AddRow() if your output was named "MyOutput".
*/
System.Data.OleDb.OleDbDataAdapter oLead = new System.Data.OleDb.OleDbDataAdapter();
//System.Data.Odbc.OdbcDataAdapter oLead = new System.Data.Odbc.OdbcDataAdapter();
//SqlDataAdapter oLead = new SqlDataAdapter();
System.Data.DataTable dt = new System.Data.DataTable();
DataSet ds = (DataSet)this.Variables.ObjVariable; // here i am getting error
ds.Tables.Add(dt);
ADODB.Record rs = new ADODB.Record();
oLead.Fill(ds, rs, "Variables");
foreach (DataRow row in dt.Rows)
{
{
Output0Buffer.AddRow();
Output0Buffer.Column = (int)row["Column"];
Output0Buffer.Column1 = row["Column1"].ToString();
Output0Buffer.Column2 = row["Column2"].ToString();
}
}
}
}
This is the error
Unable to cast object of type 'System.Object' to type 'System.Data.DataSet'.
at ScriptMain.CreateNewOutputRows()
at UserComponent.PrimeOutput(Int32 Outputs, Int32[] OutputIDs, PipelineBuffer[] Buffers)
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PrimeOutput(Int32 outputs, Int32[] outputIDs, PipelineBuffer[] buffers)
thanks
