all i am trying to do is :  creating a SP in VS using managed code and then trying to execute it. But every time i get the above error.
 If you can tell me how to edit connection string in this that would be very helpful. At present i am using :   Using conn As New SqlConnection("context connection=true")
 
I tried to do "" ALTER ASSEMBLY SqlServerProject1 WITH PERMISSION_SET=EXTERNAL_ACCESS""
but i get this error
 
""  Msg 10327, Level 14, State 1, Line 1
ALTER ASSEMBLY for assembly 'SqlServerProject1' failed because assembly 'SqlServerProject1' is not authorized for PERMISSION_SET = EXTERNAL_ACCESS.  The assembly is authorized when either of the following is true: the database owner (DBO) has EXTERNAL ACCESS ASSEMBLY permission and the database has the TRUSTWORTHY database property on; or the assembly is signed with a certificate or an asymmetric key that has a corresponding login with EXTERNAL ACCESS ASSEMBLY permission. If you have restored or attached this database, make sure the database owner is mapped to the correct login on this server. If not, use sp_changedbowner to fix the problem."""

Sql Server 2005 A Fatal Error Occurred In .NET Framework Runtime

Oct 15, 2007

We've deployed an assembly to a new production sql server 2005 instance, and have been having periodic restarts of sql server. The sql server service appears to be stopping and restarting on it's own since the assembly was deployed.

We've narrowed it down to a decryption method. We haven't been able to produce the issue on a consistant basis. Even if we put a ton of load on the stored procedure calls.

The error is below we receive (I cut out some, so it would fit in the thread), we also have mdmp files, that I've attempted to debug with Visual Studio 2005 and Windbg with no success. I have all the symbols (I'm pretty sure), but I don't have much experience with WinDbg, so it's been slow going.

Here's a little about the environment.

Windows Server 2003 Enterprise x64 SP2
Microsoft SQL Server version 9.00.3042.00 SP2
16 MB physical memory
Quad 3.2 GHz Xeon
3 sets of raid drives.
c: OS
e: sql data
e: sql logs
All Sql and windows patches are up to date.

Only thing I can figure is this is something to do with the .NET libraries. When the assembly was compiled it was set to compile for any CPU. We even tried compiling on the 64 bit OS with no luck still.

If anyone has had a similar issue, it would be most helpful, thanks,
Byron

Is it possible to define your own function? If so could you give me an example.

Keep in mind that I said in SQL Server 2000. I want no CLR SQL Server 2005 solutions.

T-SQL And Visual Basic 2005 Codes That Execute A User-Defined Stored Procedure In Management Studio:How To Declare EXEC && Sp?

Jan 17, 2008

Hi all,

In my SQL Server Management Studio Express (SSMSE), I executed the following sql code suuccessfully:
--insertNewRocord.sql--

USE shcDB

GO

CREATE PROC sp_insertNewRecord @procPersonID int,

@procFirstName nvarchar(20),

@procLastName nvarchar(20),

@procAddress nvarchar(50),

@procCity nvarchar(20),

@procState nvarchar(20),

@procZipCode nvarchar(20),

@procEmail nvarchar(50)

AS INSERT INTO MyFriends

VALUES (@procPersonID, @procFirstName, @procLastName, @procAddress,

@procCity, @procState, @procZipCode, @procEmail)

GO

EXEC sp_insertNewRecord 7, 'Peter', 'Wang', '678 Old St', 'Detroit',

'Michigon', '67899', 'PeterWang@yahoo.com'

GO

=======================================================================
Now, I want to insert a new record into the dbo.Friends table of my shcDB by executing the following T-SQL and Visual Basic 2005 codes that are programmed in a VB2005 Express project "CallshcDBspWithAdoNet":
--Form1.vb--

Imports System.Data

Imports System.Data.SqlClient

Imports System.Data.SqlTypes

Public Class Form1

Public Sub InsertNewFriend()

Dim connectionString As String = "Integrated Security-SSPI;Persist Security Info=False;" + _

"Initial Catalog=shcDB;Data Source=.SQLEXPRESS"

Dim connection As SqlConnection = New SqlConnection(connectionString)

connection.Open()

Try

Dim command As SqlCommand = New SqlCommand("sp_InsertNewRecord", connection)

command.CommandType = CommandType.StoredProcedure


EXEC sp_insertNewRecord 6, 'Craig', 'Utley', '5577 Baltimore Ave',

'Ellicott City', 'MD', '21045', 'CraigUtley@yahoo.com'


Console.WriteLine("Row inserted: " + _

command.ExecuteNonQuery().ToString)

Catch ex As Exception

Console.WriteLine(ex.Message)

Throw

Finally

connection.Close()

End Try

End Sub

End Class

===========================================================
I ran the above project in VB 2005 Express and I got the following 5 errors:
1. Name 'EXEC' is not declared (in Line 16 of Form1.vb)
2. Method arguments must be enclosed in parentheses (in Line 16 of Form1.vb)
3. Name 'sd-insertNewRecord' is not declared. (in Line 16 of Form1.vb)
4.Comma, ')', or a valid expression continuation expected (in Line 16 of Form1.vb)
5. Expression expected (in Line 16 of Form1.vb)
============================================================
I know that "EXEC sp_insertNewRecord 6, 'Craig', 'Utley', '5577 Baltimore Ave',

'Ellicott City', 'MD', '21045', 'CraigUtley@yahoo.com' "in Line 16 of Form1.vb is grossly in error.
But I am new in doing the programming of T-SQL in VB 2005 Express and I am not able to change it.

Please help and advise me how to correct these problems.

Thanks in advance,
Scott Chang

Jan 23, 2008

Hi Jonathan Kehayias, Thanks for your valuable response.

I had a hard time to sumbit my reply in that original thread yesterday. So I created this new thread.

Here is my response to the last code/instruction you gave me:

I corrected a small mistake (on Integrated Security-SSPI and executed the last code you gave me.

I got the following debug error message:

1) A Box appeared and said: String or binary data would be truncated.

The statement has been terminated.

|OK|

2) After I clicked on the |OK| button, the following message appeared:

This "SqlException was unhandled

String or binary data would be truncated.

The statement has been terminated."

is pointing to the "Throw" code statement in the middle of

.......................................

Catch ex As Exception

MessageBox.Show(ex.Message)

Throw

Finally

..........

Please help and advise how to correct this problem in my project that is executed in my VB 2005 Express-SQL Server Management Studio Express PC.

[OT] User-Defined String Functions MS SQL Server 2005 Transact-SQL SQLCLR .Net

Feb 7, 2006

User-Defined string Functions MS SQL Server 2005 Transact-SQL SQLCLR (VB. Net, C#.Net, C++. Net)

Ladies and Gentlemen,

I am pleased to offer, free of charge, the following string functions MS SQL Server 2005 Transact-SQL SQLCLR (VB. Net, C#.Net, C++. Net):

AT(): Returns the beginning numeric position of the nth occurrence of a character expression within another character expression, counting from the leftmost character.
RAT(): Returns the numeric position of the last (rightmost) occurrence of a character string within another character string.
OCCURS(): Returns the number of times a character expression occurs within another character expression (including overlaps).
OCCURS2(): Returns the number of times a character expression occurs within another character expression (excluding overlaps).
PADL(): Returns a string from an expression, padded with spaces or characters to a specified length on the left side.
PADR(): Returns a string from an expression, padded with spaces or characters to a specified length on the right side.
PADC(): Returns a string from an expression, padded with spaces or characters to a specified length on the both sides.
CHRTRAN(): Replaces each character in a character expression that matches a character in a second character expression with the corresponding character in a third character expression.
STRTRAN(): Searches a character expression for occurrences of a second character expression, and then replaces each occurrence with a third character expression. Unlike a built-in function Replace, STRTRAN has three additional parameters.
STRFILTER(): Removes all characters from a string except those specified.
GETWORDCOUNT(): Counts the words in a string.
GETWORDNUM(): Returns a specified word from a string.
GETALLWORDS(): Inserts the words from a string into the table.
PROPER(): Returns from a character expression a string capitalized as appropriate for proper names.
RCHARINDEX(): Similar to the Transact-SQL function Charindex, with a Right search.
ARABTOROMAN(): Returns the character Roman numeral equivalent of a specified numeric expression (from 1 to 3999).
ROMANTOARAB(): Returns the number equivalent of a specified character Roman numeral expression (from I to MMMCMXCIX).

AT, PADL, PADR, CHRTRAN, PROPER: Similar to the Oracle functions PL/SQL INSTR, LPAD, RPAD, TRANSLATE, INITCAP.

Plus, there are CHM files in English, French, Spanish, German and Russian.

Plus, there are versions for MS SQL SERVER, SYBASE ASA, DB2, Oracle.

More than 8000 people have already downloaded my functions. I hope you will find them useful as well.

For more information about string UDFs MS SQL Server 2005 Transact-SQL SQLCLR (VB. Net, C#.Net, C++. Net) please visit the

Using User Defined Data Type (UDT) In A Sql Server 2005 Database + Window Application.

Feb 18, 2006

Hi,

I am using VS2005 C# + sql server 2005 Express edition.

I need to using a database that uses my own defined data types to define its tables columns.

I already have designed a Database projact and create the new UDT as follows:



Create a new Database project in the Visual C# language nodes.


Add a reference to the SQL Server 2005 database that will contain the UDT.


Add a User-Defined Type class.


Write code to implement the UDT.


Select Deploy from the Build menu.

Now I need to ask some quistions:

1- When I try to add a new query to a table that contains my new data type in its columns,if I try to exexute the query the next message appears:

'Execution of user code in the .Net framework is disabled. Enable "clr enabled" configuration option'.

How can I doing that??

2- I need to use that database - which has the new data type - in a traditional ' Visual C# Windows Application' instead of 'Database', but:

when I try to add a new Data Source that contains the tables that have the new data types in its definitions, the next message appears:

'<AyaDatabase.dbo.MyNewUDTTable>

User-defined types(UDTs)are not supported in the Dataset Designer.'

So, how can I resolve that problem??

please help me.

Thanks in advance for any help.

Aya.

User Defined Aggregate Problem

Feb 22, 2008

I am trying to get a random value from a select statement. The only way I thought to do this would be to make a User Defined Aggregate Function at returns one of the rows at random. For example MIN(column) return the minimum value of that column, MAX(column) returns the maximum. I would like something like RANDOM(column) to return one of the values at random.

For example: select RANDOM(Name) from Names

So I went and created a user defined aggregate function:




Code Snippet

Imports System

Imports System.Data

Imports System.Data.SqlClient

Imports System.Data.SqlTypes

Imports Microsoft.SqlServer.Server



<Serializable()> _

<Microsoft.SqlServer.Server.SqlUserDefinedAggregate(Format.Native)> _

Public Structure GetRandom

Public s As SqlString

Public x As Integer

Public Sub Init()

x = 0

Randomize()

End Sub

Public Sub Accumulate(ByVal value As SqlString)

s = New SqlString(s.ToString & "|" & value.ToString)

x = x + 1

End Sub

Public Sub Merge(ByVal value As GetRandom)

End Sub

Public Function Terminate() As SqlString

Dim d() As String = {"|"}

Return New SqlString(s.ToString.Split(d, StringSplitOptions.RemoveEmptyEntries)(Rnd() * x))

End Function

End Structure



The problem is that it wont deploy to the SQL Server because the varible "s" is not serilizable. Here is the error message:

Type "GetRandomFunction.GetRandom.GetRandom" is marked for native serialization, but field "s" of type "GetRandomFunction.GetRandom.GetRandom" is not valid for native serialization.

Can any help me with this? Is there any other way of storing the strings that will work?

Thanks,
Stuart Fox

CLR User Defined Aggregate Function

I am trying to modify the C# example given in the "Invoking CLR User-Defined Aggregate Functions" in SQL Server 2005 Books Online.

2005: Creating Aggregate Function From .NET Assembly

Jul 17, 2006

Hello,I am learning SQL Server 2005. I have (correctly) written in .NETassembly DemoSQLServer with aggregate function AvgNoMinMax in classDemo and I have added assembly to database DemoSQLServer. Now I needto create aggregate in SQL Server. I tried this way:CREATE AGGREGATE AvgNoMinMax(@v float) RETURNS float EXTERNAL NAME[DemoSQLServer].[DemoSQLServer.Demo].[AvgNoMinMax]Unfortunately I have error:Incorrect syntax near '.'.I don't know what's wrong. Please help.Thank you very much!/RAM/

Like A User Defined Aggregate Function For Concate

May 8, 2008

Hi,

I have a table T1 with two fields. Field1 has repeated values and Field2 has unique values for any given Field1 value. F1 can have maybe 1000 different values while F2 maybe 20.

I would like to create a T2 table where Field1 has unique values and Field2 contains the concatenation of T1.Field1 values for each Field1 value.

T1
F1F2
1a
1b
2a
2c
2d

T2
F1F2
1ab
2acd

It is like a user defined aggregate function for concatenation. Any idea?

Managed C++ User-defined Aggregate Function

Mar 16, 2007

Hi 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,

CLR User-defined Aggregate Support Java/J#?

May 18, 2006

I want to write a Java User-defined aggregate (UDA). Shall I use J#?

I converted the C# example given in books online to J#. I am getting this error (as well as whole bunch of warning when I create the assembly.)

Msg 6558, Level 16, State 1, Line 1

CREATE AGGREGATE failed because type 'Concatenate' does not conform to UDAGG specification due to method 'Init'.

Msg 6597, Level 16, State 2, Line 1

CREATE AGGREGATE failed.

btw, I have the use unsafe assembly options when creating the assembly otherwise I get this error:

Msg 6265, Level 16, State 1, Line 1

CREATE ASSEMBLY failed because type "com.ms.vjsharp.cor.COMUtils" in safe assembly "vjscor" has a pinvokeimpl method. P/Invoke is not allowed in safe assemblies.

Warning: The Microsoft .Net frameworks assembly 'vjscor, version=2.0.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a, processorarchitecture=x86.' you are registering is not fully tested in SQL Server hosted environment.

From the warning, I can tell the J# UDA is not tested.

Can someone confirm whether J# UDA is supported or not?

Thanks!

Error Msg: Login Failed For A User . For VS 2005 Websites With SQL Server 2005

May 30, 2008

Just installed SQL Server 2005 and tested my old VS 2005 ASPnet websites, which were connected toSQL Server 2000 databases before.  All my websites were created for local HTTP applications, coded with a connection string with User ID and Password.   The SQL Server 2000 was configured as mixed authentication (i.e. with User ID and Password).  These websites worked very well with SQL Server 2000 database server.Testing my old VS 2005 websites with SQL Server 2005 database, showed a 'Login failed for a User ''.' error msgalthough the 'Test Connection' on VS 2005 design showed a perfect query for e.g. a GridView control.  I have assured that the UserID/Password were correct for Management Studio Security object'slogin and Database Security's user.  The server instance was configured with mixed authentication mode.  One thing I am not sure of is, when clicking the Management Studio icon, a Connection dialog showed up, asking for a Windows or MIxed authentication?  I just stayed with the Windows authentication.  What does the authenticationmode have anything to do with the VS 2005 website connection?  Should I change to mixed authetnication mode?TIA,Jeffrey

A Transport-level Error Has Occurred When Receiving Results From The Server. - After Installing New Instance Of SQL Server 2005 W/NO App Changes

Sep 27, 2006

We've devoted a resource to this today, but I have to believe it's something easy that we're overlooking.  The scneario is that we have a production Web application that until last weekend had a SQL 2000 back end.  This weekend we installed a new instance of SQL 2005 and everything works (we tested in a sandbox environment, but someone must not have load tested enough) and never saw these exceptions.   So, after the upgrade we now receive 100's of thexe SQL excptions per day:A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)Does anyone know what we've overlooked that's causing this issue?Thanks for any help!

SQL Server 2005: Question About Creating A User For A Database

Dec 12, 2005

I'm not a DBA, so I don't know where to look for information on this.

In SQL Server 2005, I can simply no longer create a user for the database I created. It asks that the user be associated with a login. That login is found in the Security folder of the database instance.

The question is: what is this instance security folder for? I don't recall having to do this in SQL Server 2000.

Any elaboration or links to such information would be appreciated.

Creating Databases Under MS SQL 2005 Server (SP-2): Dbo User Role

Jun 9, 2007

Good Day,



I am having a problem with creating databases in MS SQL 2005 Server. When I attempt to assign an User Mapping for my SQL user account to the newly created database, the "dbo" user and schema is already assigned. When I try to drop this user in favor of my own, I receive an error message: Cannot alter the user "dbo" (Microsoft SQL Server, Error: 15150). I am connected to my database engine through the "sa" account.

An Error Has Occurred While Establishing A Connection To The Server. When Connecting To SQL Server 2005, This Failure May Be Caused By The Fact That Under The Default Settings SQL Server Does Not Allow Remote Connections.

Jan 22, 2008

My site works fine in VWD2008 express, but I get this error when I try to use it on my live website.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. 
According to this article: http://support.microsoft.com/kb/914277  I am supposed to:




1.
Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
Ok, there is no such program in this folder.  The only thing in there is "SQL Server Error and Usage Reporting"...
 The other thing I am greatly concerned with is this:  All is want is for my webpages to be able to access my database for user authentication.  I DO NOT want to grant the internet rights to remote connect to my database.

.NET Framework :: Error In Creating CLR Functions Saying Server Is Information Protection Configured

Aug 17, 2011

We have few C# binaries that contains definition of CLR functions, and one stored procedure to install / create them in our database. Recently when dropping and recreating the CLR function using our stored procedure, it failed with below error:

Error/info returned: [Microsoft][ODBC SQL Server Driver][SQL Server]This server is Information Protection configured. Only the sql server web application can be used for this function. ([URL])[Microsoft][ODBC SQL Server Driver][SQL Server]The transaction ended in the trigger. The batch has been aborted.

Basically our stored procedure has standard steps to create asymmetric key for each of our C# binary and create login for that key and then grant unsafe assembly permissions to those logins.

It sets show advanced options, clr enabled, and ole automation procedures options. It then using create assembly (for each c# binary with permission_set = unsafe) and create function constructs to create clr functions in SQL server.

Execution Time Anomaly In Stored Procedures In SQL Server 2005

Dec 3, 2006

Background: We have SQL Server 2005 x64 running on a quad-core (dual dual-core) machine with 16GB of RAM. The database is about 10GB in size and we execute around a million stored procedures a day on it. Our application uses about 1000 different stored procedures on this machine. The application is a transactional B2B web-app with about 2000 users.
The problem we have is a really odd one that I can't seem to find much information on. We have a small number (3-4) of stored procedures that's exibiting this problem.
The stored proc in question takes on average 100ms CPU time to execute. It's a fairly complex stored proc, about 300 lines long, 6-7 select statements and it uses temp tables. No updates / inserts except for on the temp tables. It's executed about 5000 times per day. About once a week, though, execution times will suddenly jump up to 3000 ms average. This happens randomly during the day, although it seems to happen more often on Monday mornings (the DB is mostly unutilized over the weekend)
To fix this, I force the DB to recalculate the execution plan by adding / removing (depending what I did last time around) the line 'set arithabort on' at the top of the stored procedure. I have no idea why this works, but it does. Within seconds of changing it, the stored proc execution time will go back to it's normal range of 60-150ms.
I've tried setting the execution plan of the stored procedure but I can't get it to work - the execution plan is very long and I don't know how to debug the error I get.
What is happening? This happens with a couple of stored procedures - usually the more complex ones. Has anyone seen anything like this?

How To Drop A User Defined Database Role In 2005?

I am quite annoyed because the "owned schema" is db_owner, which can not be unselected. Quite an innovation. How do I drop this relationship?

I get the following error and have been trying to figure out why I keep getting it.  Initially, I had placed my project under wwwroot folder and ran it under IIS and it gave this error.  Then I moved it to my local C drive and same thing.  I am sharing this project with two other co-workers and all our config files and code files are same...they don't get this error but I do.  I checked that SQL Server Client Network Utility has TCP/IP and the 'Named Pipes' enabled.  I thought maybe I have setting in the Visual Studio 2005 that I'm not aware of that's causing this problem...it can't be the server since my co-workers aren't having this error and can't be anything in the code since all of us are sharing this project through vss.  I dont' think using different version of .net framework can create this error.  I changed the version from 2.0 to use 1.1x and it gave same error... Any help would be greatly appreciated.  Thanks in advance.
 
Server Error in '/RBOdev' Application.
