SQL Schema And Managed Code (SQL-CLR)
Nov 20, 2006I have a SQL Server project in Visual Studio 2005 which deploys an assembly to SQL Server 2005 containing various stored procedures user defined functions. Is there any way to tell Visual Studio to drop/create the stored procedures in a schema other than dbo?
ie: User.ChangePassword instead of dbo.ChangePassword.
Database Trigger To Run Managed C# Code
Aug 24, 2007Hi there,
Values in my database need to updated periodically. The code, upon starting the application, queries the database and stores the values in the Application collection. This is to avoid making a database call everytime the values are needed (increases performance). The drawback is that changes to the database values are not updated in the code.
How can I create a database trigger that will update the C# Application colllection whenever a table value is updated?
Managed Code Memory Issues
Apr 19, 2007There is an interesting article from MSDN Magazine titled "Identify and Prevent Memory Leaks in Managed Code"
http://msdn.microsoft.com/msdnmag/issues/07/01/ManagedLeaks/default.aspx
Are there any additional documents or utilities that people would suggest for monitoring and managing CLR impact on SQL server resources and performance?
Config Files For .Net Code In Managed Sprocs
Oct 3, 2006I have been attempting to create a managed stored procedure which calls a web service using WSE 3.0 for security.
It appears that the WSE-generated config file (or possibly the app.config file) is not accessible to the .Net code.
Is there a method for using config files with CLR managed sprocs?
Thanks,

RCW Proxy Is Not Be Able To Provide Messages To My Managed Code
Jan 10, 2007Hi everyone,
Primary platform is Framework 2.0
Our current service throws on-demand .DTSX and now we'd like that will throw old ETL 2000 too.
I'd like to know if success or not success when calling dtspkg.dll from my managed code (vb).
Is it possible or not? I only capture errors for the sake of TRY..END TRY but I don't know how the hell to know
if the dts execution was successful.
Execute method not returns anything.
Currently my schema is the following:
paquete = New DTS.Package2
paquete.LoadFromSQLServer("SRVDESA1", , , DTS.DTSSQLServerStorageFlags.DTSSQLStgFlag_UseTrustedConnection, _
, , , "pruebaenric")
paquete.FailOnError = True
Try
paquete.Execute()
Catch ex As Exception
' stuff
End Try
paquete = Nothing
I've tried to use WITHEVENTS but it's useless at all from there.
Events are not fired. I though that RCW created for this could be able to call them...
Private Withevents paquete as dts.package2
Private paquete_OnError()
stuff
Private paquete_OnProgress()
stuff
Thanks for any input related with,

Dynamic Creation Of Temp Tables Using Managed Code
Jan 23, 2008
Hi,
I have a requirement to create #Temp table in database and insert values to it.
I use following code:
DbCommand dbCreateTable;
dbCreateTable = provider.CreateCommand();
dbCreateTable.Connection = conn;
dbCreateTable.CommandText ="Create table #MyTemp (Id varchar(10))";
dbCreateTable.ExecuteNonQuery();
string[] insertValues = {"Insert into #Mytemp values ('TestString1')",
"Insert into #Mytemp values ('TestString2')"};
DbCommand dbInsertData = provider.CreateCommand();
dbInsertData.Connection = conn;
foreach (String insertStr in insertValues)
{
dbInsertData.CommandText = insertStr;
dbInsertData.ExecuteNonQuery();
}
Code creates the Temp table but when it comes to insert statement, it throws error saying "Temp table not found".
Reason can be Create and Insert statement gets executed as 2 different sessions.
How to get the above requirement work fine?
Thank you.

Store The Output Of Sp_executesql - Solved With Managed Code
Apr 18, 2006hi
I am trying to store the output of sp-executesql into a variable to implement it as a user defined function later
The function is
ALTER function [dbo].[UnitsAvailable] (@id int)
returns int
as
begin
declare @sql nvarchar(100)
declare @params nvarchar(500)
declare @count nvarchar(10)
set @sql = N'Select count(*) from units where projectid=' + convert(varchar,@id) + 'and sold=0 and displayunit=1'
set @params = N'@countOUT nvarchar(10) OUTPUT';
exec sp_executesql @sql, @params, @countOUT=@count OUTPUT;
return @count
end
The result is that I am able to parameterize the sql end execute with the right result. The only problem is that the value is not stored in the variable @count. I could get to the same result using managed code in sql 2005 but still I am curious to find out where the problem is ....
Can you please help?
Thanks Alex
Managed Code In SQL Server 2005 And Stored Procedure Name Qualification
Mar 11, 2008All --
Please help.
I am using managed code in SQL Server 2005 and have a question about stored procedure name qualification.
With a VS.NET 2005 Pro Database project, when I use >Build, >DeploySolution, it works great but my stored procedures are named with qualification using my domainusername.ProcName convention, something like this...
XYZ_TECHKamoskiM.GetData
...when I want them to be named with the dbo.ProcName convention, something like this...
dbo.GetData
...and I cannot see where this can be changed.
Do you happen to know?
Please advise.
(BTW, I have tried going to this setting >Project, >Properties, >Database, >AssemblyOwner, and putting in the value "dbo" but that does not do what I want.)
(BTW, as a workaround, I have simply scripted the procedures, so that I can drop them and then add them back with the right names-- but, that is a bit tedious and wasted effort, IMHO.)
Thank you.

Does Sql Server 2005 Enterprise Edition Support Managed Code ?
Aug 4, 2006
Dear friends,
please help,
let me tell you what happens,
1) first i installed Sql Server 2005 Enterprise Edition, everything was working fine except i was not able to create managed objects from BI, like stored procedures, triggers, UDT, etc etc.
2) so i installed VS.net 2005 complete + Sql Server 2005 Express Edition
now i was able to create stored procedures, triggers, etc etc, i'm talking about the CLR objects, ok, i.e. the managed code, but........ i was only able to do this from Sql Server 2005 Express Edition.
whenever i try to create managed objects CLR like stored procedures and stuff from the Sql Server 2005 Enterprise edition it gives me the following error :
"The Sql Server supplied by these connection properties, does not support managed code, please choose a different server"
please help meeeee.. please please, tell me what's the problem ?
below i'm attaching a screenshot of the error....
Making Managed Code Calls Inside SQL Server In Context Of The Client
Aug 17, 2006Dear all,
I am very new to the subject of writing CLR code inside SQL Server, so I apologise if my questions seem naive.
I have a requirement to populate an asp.net 2.0 GridView control with data columns, some of which are directly from a SQL Server 2005 database, but some of which are calculated by calling CLR methods passing the values from the database columns to those methods.
However, the methods I need to call only make sense in the process context of the client web site which is calling the stored procedure which I want to write to return the data columns.
In effect, I want to be able to make a remote procedure call from within the SQL Server CLR code to the methods available in the client process.
Is this possible? If so, could someone please refer me to an example of how to do it.
If it can be done, it opens up lots of very cool possibilities!
Thanks.
Problem With Managed Code Simple Example Target String Size Is Too Small To Represent The XML Instance
Feb 10, 2006
I am trying to understand creating SQL Server projects and managed code. So I created a C# SQL Server Database project and named it "CSharpSqlServerProject1" and followed the steps in the following "How to: " from the Help files:
"How to: Create and Run a CLR SQL Server Stored Procedure "
I used the exact code in this "How to: " for creating a SQL Server managed code stored procedure (see below) in C#. However it didn't even compile! When I went to build the code I got the following error message:
"Error 1 Target string size is too small to represent the XML instance CSharpSqlServerProject1"
It does not give a line number or any further information! Since this is a Microsoft example I'm following I figure others must have run into this too. I can't figure out how to fix it!
Here's the code as copied directly from the howto:
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
public partial class StoredProcedures
{
[SqlProcedure()]
public static void InsertCurrency_CS(
SqlString currencyCode, SqlString name)
{
using (SqlConnection conn = new SqlConnection("context connection=true"))
{
SqlCommand InsertCurrencyCommand = new SqlCommand();
InsertCurrencyCommand.CommandText =
"insert Sales.Currency (CurrencyCode, Name, ModifiedDate)" +
" values('" + currencyCode.ToString() +
"', '" + name.ToString() +
"', '" + System.DateTime.Now.ToString() + "')";
InsertCurrencyCommand.Connection = conn;
conn.Open();
InsertCurrencyCommand.ExecuteNonQuery();
conn.Close();
}
}
}
Thanks for any help you can give!

Managed Trigger And New Threads
Mar 12, 2007SQL Server 2005 gives you a possibility to create managed triggers. In a managed trigger I can create a new thread and process trigger event in various ways. My question is that are there any reasons why I should NOT start new threads in database triggers? The following code shows how I could create new threads. Do you see that this could cause any errors or problems in SQL Server functionality? My goal is to minimize the trigger effects in a database overall performance.
'This handles database updates of AdventureWorks Person.Contact table.
<Microsoft.SqlServer.Server.SqlTrigger(Name:="UpdateContact_Trigger", Target:="Person.Contact", Event:="FOR UPDATE")> _
Public Shared Sub UpdateContact_Trigger()

Dim triggContext As SqlTriggerContext = SqlContext.TriggerContext()
'Ensure that it was update:
If triggContext.TriggerAction = TriggerAction.Update Then
'Open a connection:
Using conn As New SqlConnection("context connection=true")
conn.Open()
'Fetch some information about the update:
Using sqlComm As New SqlCommand
sqlComm.Connection = conn
sqlComm.CommandText = "SELECT ContactID, FirstName, LastName from INSERTED"
Using rdr As SqlDataReader = sqlComm.ExecuteReader
If rdr.Read Then
'Process the data in a separate thread. The thread could send a message to MSMQ about the change
'or process if differently. The purpose of using separate thread is avoid performance hit
'in the application / database operation.

How Are Device Cals Managed And Assigned.
Aug 21, 2007Hello all,
This seems like a simple question but I still haven't been able to get an answer from Microsoft Canada. We're looking at buying 75 device cals to connect to a single instance of SQL Server Standard Edition. Our question is on how those licenses are assigned and/or activated.
Do we need to manually do something for each station or is it an automated process done the first time a station connects to the server? We also wat to understand what happens when a workstation dies and is replaced by another one. Do you have to do something on the server to transfer the license to the new station ?
In other words, when using device cals (and/or user cals), do you have to do any type of license management or is it all transparent ?
XML Source, Created From Managed DTS, Getting An Error
Oct 19, 2007Hi,
I am stepping into the world of developing SSIS packages as part of a project I am working on, and I am kicking the tires at the moment, and I am having a couple of problems.
First, is there a really good source of 'how-to's in terms of developing against SSIS. There is plenty of documentation on MSDN/Technet, but there are NO books which cover managed DTS in ANY kind of depth.
Secondly, I am looking at bringing in an XML file programatcially, and linking in the columns I need. Works fine using the BI tools, but I get an error when I do it from visual studio.
The following code :
Code Block
IDTSComponentMetaData90 xmlinputfile;
Package package = CreatePackage("SSISPackage", "Test Package");
MainPipe pipe = AddDataFlowTask(package);
pipelineEvents = new ComponentEvents();
xmlinputfile = pipe.ComponentMetaDataCollection.New();
// configure it up...
xmlinputfile.ComponentClassID = "Microsoft.SqlServer.Dts.Pipeline.XmlSourceAdapter, Microsoft.SqlServer.XmlSrc, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91";
xmlinputfile.Name = "XML Source";
xmlinputfile.Description = "Source data in the data flow...";
CManagedComponentWrapper instance = xmlinputfile.Instantiate();
instance.ProvideComponentProperties();
// At this point you would normally associate with the runtime connection manager,
// but as it is an xml file, we do not need to do that
// We need to set the appropriate properties to look at our xml file...
instance.SetComponentProperty("XMLData", @"C:filechangedtoprotecttheinnocent.xml");
instance.SetComponentProperty("XMLSchemaDefinition", @"C:filechangedtoprotecttheinnocent.xsd");
instance.SetComponentProperty("AccessMode", 0);
instance.SetComponentProperty("UseInlineSchema", false);
// We need to set output connections....
instance.AcquireConnections(null);
instance.ReinitializeMetaData();
instance.ReleaseConnections();
IDTSVirtualInput90 vInput = xmlinputfile.InputCollection[0].GetVirtualInput();
// Iterate through the virtual input column collection.
foreach (IDTSVirtualInputColumn90 vColumn in vInput.VirtualInputColumnCollection)
{
}
When I go anywhere near the InputCollection[0], watch throws an exception, and the call to GetVirutalInput() throws the same exception which is :
System.Runtime.InteropServices.COMException was unhandled by user code
Message="Exception from HRESULT: 0xC0048004"

Does anyone have any kind of clue as to what is going on. I have seen comments on here from other people in regards to errors with input columns?? The XML files work fine in the editor as I said, and the XSD was generated by the editor using the Generate XSD option.
Error Deploying Managed Stored Proc

Access To The ADO.net Managed Provider 'SqlClientFactory' Was Denied
Apr 12, 2006In a previous post in Installation and Setup I was having problems just getting an ASP.NET 2.0 app to run on my web server. Now I'm having some different weird security issues.
I'm getting this message when just trying to open a database and put its contents into a gridview.
Access to the ADO.net Managed Provider 'SqlClientFactory' was denied in the data source with ID 'sqlEmployees' because of security settings.
I think this may have to do with our web server and our SQL server being separate machines. That always gives us issues. But I have impersonation=true in my web.config along with windows authentication and I have SQL Server configured with Windows and SQL authentication so things should be right, I'm thinking.
Any ideas??

View 2 Replies View RelatedCan A Managed Udf Contain A Static Dictionary&&<&&>? Is This A Wise Idea?
May 17, 2007I currently have a udf written in T-SQL that's getting way too logically complicated!
It€™s typically accessed like this:
SELECT PartNumber,dbo.PartPrice(Manufacturer, Model, AssemblageInfo, Version, CustomerDiscountLevel) FROM WorkOrders where OrderNumber=123456
The udf does some complicated manipulations on the parameters and eventually does a SELECT on a lookup table and returns the result.
If I make this a managed code udf, the logic gets much simpler to write (great!).
But, my question is:
Can I take the lookup table and embed it in the udf--so the udf doesn't have to go to the database to do the lookup?
Would I do that in a STATIC dictionary<>?
Is it wise to keep the info statically?
The lookup table consists of 3600(+/-) elements and changes exactly once a month.
The SELECT statement using the udf typically returns several thousand rows.
The SELECT is done often.

Sp_sproc_columns Does Not Seem To Work On Managed Stored Procedures
Jul 10, 2007Hi,
I have written a stored procedure using C#.NET. I deployed it to SQL Server, and everything works fine.
However, an Third-Party app needs to see what parameters it can use for this SP by executing sp_sproc_columns <SP name>
sp_sproc_columns
Seems to work on normal SP's written in T-SQL, but not on Managed SP's. On my SP, sp_sproc_columns does not seem to work. It does not return the parameters. On normal SP's, it does.
Anyone have an idea why this is?

Login Without Connect Permission Somehow Managed To Become Db_owner!?
Jan 9, 2007I tried asking the same question in other forum but couldn't get an answer.
I used exactly the following SQL to create a login with sa account in SQL2k5 Management Studio:
Create Login yy With Password='yy123Z'
Without granting any permission, straight away, i log out sa and login as yy in management studio, yy somehow can access one of my ApplicationDatabase! So i check with the following SQL in my ApplicationDatabase:
IS_MEMBER('db_owner')
and it returns me 1, meaning yy is db_owner. I then quickly login as sa and double check on the security|login|yy|properties|User Mapping, NONE of the database is mapped! and i also ensure "Guest account enabled for: ApplicationDatabase" is unchecked.
What could be the problem i am facing? the purpose i create yy is to ONLY allow it to have connect permission on my SQL Endpoint. Please HELP!!
Managed C++ User-defined Aggregate Function
Mar 16, 2007Hi all,
I'm attempting to write an aggregate function in C++ to compare performance with the equivalent function in C#.
However, I'm having problems getting SQL Server to see the function in the assembly. It allows me to load the assembly into the database, but I can't see the type in it.
Here's my code:
// CPPTest.h
#pragma once
using namespace System;
using namespace Microsoft::SqlServer::Server;
using namespace System::Data::SqlTypes;
using namespace System::Data::SqlClient;
namespace CPPTest {
[Serializable]
[Microsoft::SqlServer::Server::SqlUserDefinedAggregate(
Format::Native,
Name="AGG_CPP_OR")]
public ref struct AGG_CPP_OR
{
public:
void Init();
void Accumulate(SqlInt32 Value);
void Merge(AGG_CPP_OR^ Group);
SqlInt32 Terminate();
private:
SqlInt32 m_accum;
};
}
// CPPTest.cpp
#include "stdafx.h"
#include "CPPTest.h"
void CPPTest::AGG_CPP_OR::Init()
{
m_accum = 0;
}
void CPPTest::AGG_CPP_OR::Accumulate(SqlInt32 Value)
{
m_accum = m_accum | Value;
}
void CPPTest::AGG_CPP_OR::Merge(CPPTest::AGG_CPP_OR^ Group)
{
m_accum = m_accum | Group->m_accum;
}
SqlInt32 CPPTest::AGG_CPP_OR::Terminate()
{
return m_accum;
}
Compile it with /clr:safe option and it can be loaded as an assembly into SQL Server 2005 (9.0.1399), but the AGG_CPP_OR type is not seen as an aggregate function. I've also tried implementing IBinarySerialize and setting Format to Format::UserDefined (and putting in MaxByteSize) but it makes no difference.
Does anyone know what I'm missing here?
Many thanks,
