SQL Server 2000 Extended SP Built Using .NET 1.1 (Is It Possible?)
May 20, 2008
Hello Pros,
I have a .NET 1.1 component that I want to use as an extended stored procedure in SQL Server 2000. Is this possible? FYI, I read in many sources (e.g. MSDN blogs) that creating extended stored procedures can only be done using a low level language such as C/C++.
I am wondering if it's possible to expose this component as a COM component using the .NET interop library, then register it with SQL Server 2000, and finally be able to consume it from TSQL?
Help please,
Yousef

Extended Memory For SQL7 On Advanced Server 2000
Jan 24, 2002Could anyone inform me how much the conventional memory SQL7 Enterprise on Advanced Server 2000 can have?
The SQL is on an active/active cluster. Currently each runs at 2GB of memory, with available memory for failover. I am planning to add another 2GB to each SQL node. Is this possible? Are there any configurations I need to do? Do I need to set AWE enabled? and How much?
Your help is greatly appreciate.

Performance Of Extended Stored Procedures In SQL Server 2000
Jul 23, 2005What is the overhead of using extended stored procedures?I created a table with 500,000 rows.1) I ran a select on two columns and it runs in about 5 seconds.2) I ran a select on one column and called an UDF (it returns aconstant string) and it takes 10 seconds.3) I ran a select on one column and called a UDF that calls an extendedstored procedure that returns a string and it takes 65 seconds.I also tried running test 3 with 4 concurrent clients and each clienttakes about 120 seconds.

Nov 17, 2007Dear All,
We have a DB on sql server 2000 64 bit and the build is 2187.
The database consisted of two transaction log files and several data files at the time we took backup. However, the backup taken was a cold backup (backup of files through OS). In this backupset, one transaction log file was skipped due to some error...... Now I want to restore the database for referring to some history data. Will I be able to attach the database with all MDF and one of the transaction log files.??
I heard this kind of recovery is not possible. If anybody can post some solution , I would be grateful...!!

Can't Re-attach Database To Sql Server 2000
Dec 25, 2006Hi,
My last post was terminated without the error message. To recap, I am unable to re-attach a database to a SQL server 2000 server after I detached it and attached it to a 2005 Server. When I detached it from the 2005 server and tried to re-attach it to the 2000 server I got the following error message:
" Error 5123: CREATE FILE encountered operating system error 5(Access denied) while attempting to create the physical file ..."
I tried using both the 2005 Server Management Studio and the 2000 Enterprise manager to do the re-attachement but got the same error message.
Any ideas on how I can reattach the files?
Thanks for your help.

Attach/restore Databases In SQL Server 2000
Jun 19, 2007Hi,
I've got a question regarding attaching/restoring of DBs and wonder if anyone could help me out.
Does SQL Server 2000 provide a functionality to attach/restore DB automatically? ie, some kind of polling service to attach/restore DB that were detached previously?
Thanks

Msg 6573 Method, Property Or Field In Assembly Is Not Static. VB.Net Assembly In SQL Server Problem
Feb 29, 2008
I am trying to get a function I created in VB 5 for Access and Excel to work in SQL 2005. I was able to update the old VB code to work in VB 2005. I compiled and made a .dll, and I was able to register the new Assembly in SQL Server. When I try to create the Function, I get an error:
CREATE FUNCTION dbo.Temperature(@FluidName char, @InpCode Char, @Units Char, @Prop1 varchar, @Prop2 varChar)
RETURNS VarChar
AS EXTERNAL NAME FluidProps.[FluidProps.FluidProperties.Fluids].Temperature
Error returned:
Msg 6573, Level 16, State 1, Procedure Temperature, Line 21
Method, property or field 'Temperature' of class 'FluidProps.FluidProperties.Fluids' in assembly 'FluidProps' is not static.
Here is the code (part of it) in the VB class:
Header:
Imports Microsoft.SqlServer.Server
Imports System.Data.SqlClient
Imports System.Runtime.InteropServices
Imports System.Security
Imports System.Security.Permissions
Namespace FluidProperties
'Option Strict Off
'Option Explicit On
Public Partial Class Fluids
Function:
Function Temperature(ByRef FluidName As Object, ByRef InpCode As Object, ByRef Units As Object, ByRef Prop1 As Object, Optional ByRef Prop2 As Object = Nothing) As Object
Call CalcProp(FluidName, InpCode, Units, Prop1, Prop2)
Temperature = ConvertUnits("-T", Units, T, 0)
End Function
If I change the Function Temperature to Static, I get an error that functions cannot be Static. Its been a long time since I created the code and am having a hard time in my older age of getting the cobwebs out to make it work.
I have no problem getting the function to work if I call it from a VB form....so what do I need to do to get it to work on data in my SQL server?
Thanks

ALTER ASSEMBLY Error Msg 6509 An Error Occurred While Gathering Metadata From Assembly ‘&&<Assembly Name&&>’ With HRESULT 0x1.
Feb 22, 2008I work with February CTP of SqlServer 2008.
I have an Assembly with several UDTs inside. Version of assembly is 1.0.*
I use CREATE ASSEMBLY statement to register this assembly, and it runs without any errors. Then I rebuild CLR solution without doing any changes in source code. In that case the only difference between new and old assemblies is version (difference in fourth part of version).
Then I try to update assembly in SqlServer. I use
ALTER ASSEMBLY <name>
FROM <path>
WITH PERMISSION_SET = UNSAFE, UNCHECKED DATA
statement for this. Statement runs with error:
Msg 6509An error occurred while gathering metadata from assembly €˜<Assembly name>€™ with HRESULT 0x1.
I found the list of condition for ALTER ASSEMBLY in MSDN:
ALTER ASSEMBLY statement cannot be used to change the following:
· The signatures of CLR functions, aggregate functions, stored procedures, and triggers in an instance of SQL Server that reference the assembly. ALTER ASSEMBLY fails when SQL Server cannot rebind .NET Framework database objects in SQL Server with the new version of the assembly.
· The signatures of methods in the assembly that are called from other assemblies.
· The list of assemblies that depend on the assembly, as referenced in the DependentList property of the assembly.
· The indexability of a method, unless there are no indexes or persisted computed columns depending on that method, either directly or indirectly.
· The FillRow method name attribute for CLR table-valued functions.
· The Accumulate and Terminate method signature for user-defined aggregates.
· System assemblies.
· Assembly ownership. Use ALTER AUTHORIZATION (Transact-SQL) instead.
Additionally, for assemblies that implement user-defined types, ALTER ASSEMBLY can be used for making only the following changes:
· Modifying public methods of the user-defined type class, as long as signatures or attributes are not changed.
· Adding new public methods.
· Modifying private methods in any way.
But I haven€™t done any changes in source code, so new version of assembly satisfies all this conditions.
What could be the reason for such behavior?
P.S. I€™ve got the same error, if I add or change any method in assembly before rebuilding.

Attach SQL 7.0 DB To A SQL 2000 Machine
Aug 5, 2002I need to move a DB that's on a SQL 7.0 box to a SQL 2000 box for consolidation. I cannot upgrade the 7.0 box to 2000 at this time. I tried reattaching it on the 2000 box and it gave me some errors about versions mismatched. Would DTS be the best way to pull it over? If not, what's the recommended operation?

Failed To Load Expression Host Assembly. Details: StrongName Cannot Have An Empty String For The Assembly Name.
Jan 12, 2006I previously had an ASP.NET 1.1 site running on my IIS 6.0 server (not the default website) with Reporting Services running in a subdirectory of that website. I recently upgraded to ASP.NET 2.0 for my website and was greeted with an error when trying to view a report. The error was very non-descript, but when I checked the server logs, it recorded the details as "It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process."
First of all, I could not figure out where and how to do this. Secondly, I decided to try to also change the Reporting Services folders to run ASP.NET 2.0 and when I did, I was greeted with the following message when attempting to view a report:
"Failed to load expression host assembly. Details: StrongName cannot have an empty string for the assembly name."
Please help.
Creating A System.Management Assembly In Order For My Own Assembly To Work?
Aug 2, 2006Hi
I am a bit paranoid about what I just did to my SQL Server 2005 with this CLR experiment.
I created a Class Lib in C# called inLineLib that has a class Queue which represents an object with an ID field.
in another separate namespace called inLineCLRsql, I created a class called test which will hold the function to be accessed from DB, I referenced and created an instances of the Queue class, and retrieve it's ID in a function called PrintMessage.
namespace inlineCLRsql{
public static class test{
public static void PrintMessage(){
inLineLib.Queue q = new inLineLib.Queue();
int i = q.queueId ;
Microsoft.SqlServer.Server.SqlContext.Pipe.Send(i.ToString());
}
}
}
to access this from the db, I attempted to create an assembley referencing inLineCLRsql.dll. This didn't work as it complained about inLineLib assembly not existing in the db. I then attempted to create an assembley for inLineLib but it barfed saying System.Management assembly not created.
so what I did is (and this is where I need to know if I just ruined sql server or not):
1- ALTER DATABASE myDB SET TRUSTWORTHY ON;.
2- CREATE ASSEMBLY SystemManagement
FROM 'C:WINDOWSMicrosoft.NETFrameworkv2.0.50727System.Management.dll'
WITH PERMISSION_SET = UNSAFE
3- CREATE ASSEMBLY inLineLibMaster
FROM 'D:inLineServerinLineLibinDebuginLineLib.dll'
WITH PERMISSION_SET = unsafe
4- and finally
CREATE ASSEMBLY inLineLib
FROM 'D:inLineServerCLRSQLinlineCLRsqlinDebuginlineCLRsql.dll'
WITH PERMISSION_SET = SAFE
Everything works after those steps (which took some trial and error). I can create a sproc like:
CREATE PROC sp_test AS
EXTERNAL NAME inLineLib.[inlineCLRsql.test].PrintMessage
and it returns the Queue ID
Is there anything unadvisable about the steps above?
Thanks for your help

Backup/Restore Vs Attach/Detach 2000 Database To 2005
Jul 15, 2006I'm trying to see the differences between Backup/Restore and Attach/Detach. I backup and detach a database from SQL Server 2000 SP3 and then attach and restore it to SQL Server 2005 SP1.
The differences I noticed are:
1. The restored database has a much larger initial size (database size is same) for data and log.
2. The attached database has a last backup date
3. If the backup is restored over a database, the restored database is showing owned by the database owner of the database restored over but syslogins and sysusers do not match.
I don't understand why #1 happens.
Are there any other differences between Backup/Restore and Attach/Detach?
Thanks,
Peter

Error Registering Assembly Using CREATE ASSEMBLY
May 1, 2008We have written a test CRL stored procedure to test replacing one of our complex stored procedures but can€™t get it deployed to our SQL server that hosts a mirrored configuration of our production database (very locked down). It works fine on our development instances (not very locked down). It only references the default assemblies that were added when we created the project. All it does is use Context Connection=true to get data, loops though some records and returns the data using SQLContext. CLR is enabled on SQL server, the assembly is strongly signed, and we tried deploy using the binary string with the SAFE setting.
CREATE ASSEMBLY for assembly 'SQLCLRTest2' failed because assembly 'SQLCLRTest2' failed verification. Check if the referenced assemblies are up-to-date and trusted (for external_access or unsafe) to execute in the database. CLR Verifier error messages if any will follow this message
[ : SQLCLRTest2.StoredProcedures::GetLift][mdToken=0x600001e] Type load failed.
[token 0x02000008] Type load failed.
Error: CREATE ASSEMBLY For Assembly
May 31, 2007I am trying to deploy a Database Project with Visual Studio 2005 and SQL Server 2005 Standard.
I import €œSystem.IO€? and have therefore set the permission levels to EXTERNAL_ACCESS.
I am receiving the same error message that many folks have received.
CREATE ASSEMBLY for assembly 'Images' failed because assembly 'Images' 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. Images.
My CLR access is €œon€?
I have tried
1) From master run: GRANT EXTERNAL ACCESS ASSEMBLY to [BuiltinAdministrators].
2) From master run: GRANT EXTERNAL ACCESS ASSEMBLY to €œMy Windows Authentication ID€?.
3) Run ALTER DATABASE MYDATABASE SET TRUSTWORTHY ON
4) In Visual Studio .NET 2005 Set the permission levels to €˜external€™
5) Tried BuiltinAdministrators and my SQL Server Windows Authenticated Login ID for the ASSEMBLY OWNER.
I can compile BUT NOT DEPLOY
Any help would be greatly appreciated.

CREATE ASSEMBLY Using Assembly Binary?!?!
Mar 8, 2006I was trying to understand how VS.NET2005 was deploying .NET CLR assemblies to SQL2005 so I ran a trace and found some interesting results.
VS.NET creates some SQL that looks pretty interesting:
CREATE ASSEMBLY [AssemblyNameHere]
FROM 0x4D5A90000300000004000000FFFF000......<continue binary data>
WITH PERMISSION_SET = EXTERNAL_ACCESS
Boy howdy!
I have tried to reproduce this and create my own deployment application but I cant figure out how they create this binary stream. The info in BOL is not much help and I have not found any samples anywhere on how to create this stream in c#.
Anyone out there been able to get this to work?

SQL Server Is Not Releasing Extended SP DLL
Nov 3, 2006During a Wise Installation upgrade of our software, we are renaming a
directory that contains our ExtendedSP DLL. We issue a
DBCC TSWSQLXP(Free) call before doing the rename, yet SQL Server,
still "holds on" to that DLL. We install a new version, and the ListDLLs
utility (from sysinternals) lists the new DLL in the correct directory.
However, when trying to remove the renamed directory, it won't let us
remove the old DLL because it says it is in use. We can delete the NEW
DLL in the NEW directory with no problem.
I have run the DBCC call numerous times and SQL Server STILL won't
release the DLL for deletion. The only way to delete the OLD DLL is to
stop the SQL Server, delete the DLL, and then restart SQL Server. We
do NOT want to do this because there may be other processes running in
SQL Server.
Any help here would be greatly appreciated.
Sql Server 2005 Extended Procedures
Dec 11, 2006Hi,
I am trying to run a stored procedure in SQL 2005 which calls a registry value using the RegRead stored procedure which in conjunction executes a line of code. This stored procedure has previously worked in both Sql 7/2000.
However, I am getting the following error when trying to run it in SQL 2005:
Msg 22001, Level 16, State 1, Line 0
xp_regread() returned error 5, 'Access is denied.'
Does anyone know if Extended Stored Procedures are supported in SQL 2005?
Thanks,

SQL Server 2012 :: Right Way To Query Extended Events Session?
Jun 4, 2015I use this code in a utility procedure (for performance testing) but it is really slow.
For example, a session with three events is taking 5 seconds to complete this query:
DECLARE @xml xml=
(
SELECT CAST(xet.target_data AS xml)
FROM sys.dm_xe_session_targets AS xet
JOIN sys.dm_xe_sessions AS xe
ON (xe.address = xet.event_session_address)
WHERE xe.name = @name
);
with data as
(
select
convert(varchar(128),convert(varbinary(128),'0x'+n.value('(action[@name="context_info"]/value/text())[1]','varchar(128)'),1)) context
, n.value('(data[@name="duration"]/value/text())[1]','int')/1000.0 duration
, n.value('(data[@name="cpu_time"]/value/text())[1]','bigint')/1000.0 cpu_time
, n.value('(data[@name="physical_reads"]/value/text())[1]','bigint') physical_reads
[code].....
So, I was wondering (considering the buffer is usually only holding a few hundred events)
1. Is this the wrong way to query data from a ring buffer?
2. Is there any way to make this code quicker?
3. Is it better to target a file store rather than a ring buffer for this?
select geometry::STGeomFromWKB(0x0106000000020000000103000000010000000B0000001000000000000840000000000000003D

This is not the first time I see this behavior.I do not want to kill the sessions (I guess the sessions won't die anyway) neither restart the sql service
