I 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.
Are there ways in SQL server to deny connecting to a instance? Basically i am looking for a way where data is accessed only through application , even the DBA's shouldn't have access to the data though they are sysadmins? Someone told me this is possible in SQL 2014? This is only for individual access, i know i can put some encryption in app layer.
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:
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
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?
I 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."
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.
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?
how to prevent the insertion of the same entry of an unique value into the database? assume that I have a primary key username " abc" in the database and then I insert the "abc" again ,the debuggging error msg pops out saying the primary key cannot be duplicated.. how can I do an if--else statement to check the database against this unintentional inputs of the same unique data " abc"???
We utilise SQL scripts, executed via sqlcmd.exe, to upgrade the schema and common data of our database(s) when we deploy new versions of our software to a production site. At the moment we simply wait until after hours to do the upgrade and ask nicely for all users to not use the system for a while.
Obviously, asking nicely doesn't always work, and there is also the issue of scheduled server tasks and web services / web sites that operate against the database 24/7.
What are our options for putting the entire server (or preferrably just one database) into a semi-offline state so that users and services cannot connect to it while our script connects and performs the upgrade? I imagine there may be several approaches each with their own pros and cons.
If you could point me in the right direction or perhaps mention what strategy has worked for you, it would be greatly appreciated. We perform these upgrades from hundreds of kilometers away via VPNs and Remote Desktop so we can't just unplug the network cable :).
Does anyone have a good strategy or technique for preventing database drops in SQL Server 2000? I know in 2005 DDL triggers rock, but in 2000 what can you do to audit who drops a database why keeping the same permissions intact.
A server I'm working on has a very unique situation, where user tables and production tables reside on the same database. Users update / create tables or populates these tables, so it can't be a table-specific trigger. However, they give a new meaning to "kamikaze pilots" as it's not uncommon for them to "accidentally" update / insert / delete 500,000,000 + records in a single statement. I've tried educating them to use batching, but to no avail, so now I'm forced to stop these statements BEFORE they execute, based on rowcount, as they fill up the database log so quickly that it goes into recovery mode (It has a 200GB log file - insane, I know).
I recon the mosts transactions allowed should be 1,000,000 records in a single statement. Looking for database trigger to stop them from executing statements with large records?
What I want is a trigger that is specific to my DB called "JunkStuff". I only want to block a servername from connect to my super dooper DB "JunkStuff".
vendor did a full backup for his database and put some folder not being backed up by TSM, he is the owner of the database, and delete his backup later. The backup is not copy only, all the differential and log backups taken are based on his FULL backup. so they cannot be restored.
QUESTION: To prevent this happen in the future, what is the normal practices? or any way to prevent db_owner to do the ad-hoc full backup? I am thinking of using DENY backup database, or write a policy  claiming no responsibility if vendor make it happen again.
I have an application in dotnet that uses sql express. This application will be deployed on the user computer and I have to find a way to prevent the user to be able to read the data and access the structure of the database.
Is there a way to do this ? Even if the user is a local administrator of the computer ?
We 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.
I represent a software development house and we have developed a client server system based on SQL Server. Most of our customers have already purchased Enterprise License of SQL Server, therefore they own the SA Login and Password. We are bound to attach our Database with their Server on their machine.
My question is how can we stop a System Administrator of SQL Server to view our Database Structure, Queries, Data installed on their SQL Server on their machine.
Our database structure is a trade secret and we cant reveal the structure to the client.
please answer this question by email to me at farhandotcom@gmail.com
I've built a simple Visual Basic .NET project containing the following code...
Imports System Imports System.Data Imports System.Data.SqlClient Imports System.Data.SqlTypes Imports Microsoft.SqlServer.Server
Partial Public Class StoredProcedures <Microsoft.SqlServer.Server.SqlProcedure()> _ Public Shared Sub WhoAmI() Using connection As New SqlConnection("context connection=true") connection.Open() Dim command As New SqlCommand("SELECT SUSER_SNAME()", connection) SqlContext.Pipe.ExecuteAndSend(command) End Using End Sub End Class
From Visual Studio, I want to encrypt the contents of this assembly, as a proof-of-concept. Even though assembly contents are stored as varbinary(MAX) in the database, converting to varchar(MAX) will expose the code.
However, the Dotfuscator Community Edition reports the following error: "Dotfuscator Community Edition cannot operate on SQL Server applications.... please try Standard or Professional Edition."
Has anyone tried encrypting a database assembly and deploying to the database?
A good test would be to issue the following TSQL script against the database holding the assembly...
-- Does the sample code above run? EXEC dbo.WhoAmI GO -- Is the code readable? SELECT * , Convert(varchar(MAX), content) FROM sys.assembly_files
Hi, I am not sure is this a proper place for my question. All we know that creating a database can be done as the following. 1) Create a project named DBExample 2) Click Add->New Item. 3) Select SQL Databse and type a name.(Ex: Database1.mdf) A database is added to the project 4) Then add table and input values. 5) Set the primary key.... My question is I parsed a text file to form a 2d string array x. How can I convert x into the database?
Hello... I want to develop a web site having two features 1. Online Shopping2. Forums Im using SQL Server, ASP.NET and C#. Now the problem is that how do I configure the Databases. Whether I create new database for each or I marge the both things into one database. if i create saperate databases for each of the feature then users have to register for two times, first for forums and second for shopping. I dont want to do this...! I want users to register just for once. ____________Thanks in advNauman Ahmed
I downloaded the sample database AdventureWorks from microsoft . When I run the download it created the data and log files under data folder in MSQLalong with other data and log files of master databases etc. However I do not see this database in SQLserver management studio. Can some one help me how to fix this so that I will be able to see this database in management studio.
I am downloading this for SQL server reporting purpose
if i open the management studio express and trying to create a database by right clicking the server name and trying in the new query window,im getting error as
CREATE DATABASE permission denied in database 'master'.
I tried finding any info regarding this approach and I can't find any, so here I am (again!).
I'm trying to create a database using SMO on a freshly installed SQL Server Express (not going through the advanced install, not going through the surface area configuration, so a lot of things are "wrong").
I get an error
- use SMO to try and create a database; this is the pseudo-code combo used:
1. create new Smo.Database object;
2. create new primary file group and data file for that database (using Smo.FileGroup and Smo.DataFile); add them to the database.
3. invoke Create(). catch exception with the following details:
Exception details:
Microsoft.SqlServer.Management.Smo.FailedOperationException was caught HelpLink="http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=9.00.2047.00&EvtSrc=Microsoft.SqlServer.Management.Smo.ExceptionTemplates.FailedOperationExceptionText&EvtID=Create+Database&LinkId=20476" Message="Create failed for Database 'NewDatabase'.

InnerException:
{"Directory lookup for the file "C:\Documents and Settings\[...]\NewDatabase.mdf" failed with the operating system error 5(Access is denied.). CREATE DATABASE failed. Some file names listed could not be created. Check related errors."}
Seems like user rights error.
Long story short, the only way the creation step works is if I change the Log on for the SQL Express service from the default Network Service to Local System (either through code or not).
Now, I know LocalSystem is not a wise idea, but it seems to be the only way.
I know it's probably something stupid, but what am I missing?
I am attempting to load an assembly that has been stored in a table as a byte array. I have created a c# class called AssemblyLoader that takes in 2 parameters, the assembly name and the parameters for the assembly (just a query string).
From this it returns the assembly byte array using a simple sql statement within the class using the assembly name to select the assembly bytes to return from the database.
The returned byte array of the assembly is loaded using:
Assembly assembly = Assembly.Load(assemblyBytes);
This seems to be the line that SQL Server 2005 is erroring on. Do I need to add some extra assemblies to the database and if so which ones.
Error: Msg 6522, Level 16, State 1, Procedure ClientInterface, Line 0 A .NET Framework error occurred during execution of user defined routine or aggregate 'ClientInterface': System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.

Hi All, I have a web site where the user can select from a list of databases (they're actually all the same structure, but have data unique to each client). Each database is a SQL 2005 database held in the App_Data folder. This all works a treat. Each database is simply named after the client it is holding data for, and the connection string for each is stored in a database that is accessed However, what I need is a form where a database name can be entered, and I can then create a new database with the same structure as the others - including tables, indexes and stored-procedures. I know I can use the copy database wizard in the Management Studio, but that isn't an option to the users of this system (it's to be used on an intranet, and the page I'm trying to create will only be used by project managers - but these people won't have a clue when it comes to configuring databases themselves). I have scripted a database, but have no idea on how I can actually use this script from within Visual Studio and more importantly, don't know how to configue it to have the database name as a parameter. I've also seen some examples that suggest using SQL-DMO, but haven't been able to work out how to use it and according to Microsoft it shouldn't be used for new developments (http://msdn2.microsoft.com/en-us/library/ms132924.aspx). Anyway, I really hope someone is able to offer some assistance on this one as I've spent a whole day trawling forums and various web-sites trying to find a solution to this. Thanks & regards, Paul
I would like to know the sql command to generate all the scripts of a database so that I can replicate the same database for testing purpose. For instance, I need those scripts to help me re-create the database itself and indexes, triggers, and stored procedures of it if possible. I remember there was a command to display all these scripts in Sql but I forgot it. If someone knows it, please help. Thanks in advance. blumonde
I've never scripted a creation of a database and it's schema,I have started to put the script together and wondered if the following two scenarios were possible and if so could the following be possible and if so could you show me.
Scenario 1: Before the script runs it checks to see if a database of the same name exists. In this example the database name is "database1". If it does the script will stop and display a message along the lines of "You are trying to create a database, which name already exists. Please either drop or rename the current database and rerun this script."
Scenario 2:The more difficult one I think. Is that it checks to see if "database1" exists. If it does it displays a message along the lines of "The database you are trying to create already exists. Please confirm that you either want to Drop the Database" You then press a key on the keyboard to continue the script and the database is dropped. It will then tell you to rerun the script in order to create the "database1" database. Or you could even give them the option to either drop the database or rename it with "_todatdate" at the end of it, but if you can get the script to do different things with different keyboard strikes?

Hi all :)My apologies if I posted in the wrong groups, but I just jumpedin MS SQL waters, so any guidance will be appreciated.What I'm trying to do is the following process:[1] present operator with a web page (script)[2] once filled with db name and username, script will create..sql file[3] osql.exe will be called with, i presume, -i file.sql andcreate a databaseI have limited SQL knowledge, but I got the information fromEnterprise Manager when I ran 'All Tasks -Generate SQLScript' on how the .sql file should look like.I realized what are the commands that would create a fresh DB(I ran this for newly created DB), and figured my .php scriptshould create such a file.It's fairly basic, and I'm almost sure all of you know howoutputed .sql file looks like, but anyway here it is:Script is called with parameters 'six' as database name and'magarac' as user name:---------------------------------------------------------------IF EXISTS (SELECT name FROM master.dbo.sysdatabases WHERE name= N'six')DROP DATABASE [six]GOCREATE DATABASE [six] ON (NAME = N'six_Data', FILENAME = N'E:Databasepathsix_Data.MDF' , SIZE = 1, MAXSIZE = 20,FILEGROWTH = 10%) LOG ON (NAME = N'six_Log', FILENAME = N'E:Databasepathsix_Log.LDF' , SIZE = 1, MAXSIZE = 20, FILEGROWTH= 10%)COLLATE SQL_Latin1_General_CP1_CI_ASGOexec sp_dboption N'six', N'autoclose', N'false'GO....use [six]GOif not exists (select * from dbo.sysusers where name =N'guest' and hasdbaccess = 1)EXEC sp_grantdbaccess N'guest'GOif not exists (select * from dbo.sysusers where name =N'sinisam')EXEC sp_grantdbaccess N'magarac', N'magarac'GOexec sp_addrolemember N'db_owner', N'magarac'GO---------------------------------------------------------------I managed to get an exact replica of .sql file that EnterpriseManager created. It leads me to believe that this way ofautomated database creation is indeed possible.Really sorry for making you to go through all this text, butafter I get a green light on this from you guys, I'll have abit more problematic question.Is there any reason why this should not be used, or would fail?Thanks in advance :)P.S.Just as a heads-up, next part of my problem is automatedcreation of new MS SQL server login to use with new DB.
We have a production database, but due to the crippling load of somereporting tools, we are looking to have a separate reporting database.Due to it's nature, the reporting database doesn't need to be as upto date as the master, perhaps it could be refreshed every evening?What I wish to know is the best way to go about this. Replicating awhole database seems excessive as there are 7000+ tables and we don'tneed it so closely matching the production database. Log shippingalso seems out as we need the reporting database to be highlyavailable and if we keep applying transaction logs ever 15 minutes orso, we need to kick all the users out.Is there a way of scripting or automatically getting SQL Server 2k tocopy over the last full backup it did and apply this to anotherserver? Also if we used this method, what would happen to the usersstored in the database? Would I have to keep re-adding them after theupgrade?Is there a better way to tackle this problem? All help gratefullyreceived. We are running SQL Server 2000 Enterprise Edition on aWindows 2000 Server machine.Thanks.
I think its silly question but i expect some solution .
Is there any way to create sql sever database by using VB.NET code ? I have to create database,tables,sps and also transfer the data from one database to newly created database.
Please, if somebody have some solution then guide me in detail.
