I/O operations in remote sql server file system

August 5, 2016, 6:56 am

Hi. I'm facing a problem. I'm developing a web application in ASP.Net MVC 4 to bring web features to an already made desktop application, developed by other developer team. Both applications are connected to the same database. What i need to do is use part of the logic from the desktop app to send some data from one server (A) to another (B), which has both desktop and web applications as well. The DB has a stored procedure than export a file with the data that need to be sent to B. This is my idea so far to accomplish this.

- I execute the stored procedure and export the data to the file. This SP is transparent to me, was created by the other developer team and I don't know the format of this file and niether the data that store. Since this file is created from sql server, exist in the file system of the sql server that is not the same server where the web application is hosted.
- Then I take the file and send it to B through WCF.
- In B when the file is received is copied to the sql server file system.
- Finally I execute in the DB of B other stored procedure that imports the data from the file. This stored procedure also was created by the other team.

My problem is how to get the file from sql server file system to send it through WCF. Then how can I copy the file to B's sql server file system to import the data.

The file can be very large, over 4GB. My first idea was to use SQL SERVER FILESTREAM to once the file is created insert it in the DB and in that way can be access from the web app. I don't like this approach. When insert the file a duplicate of the file is created in the file system. Also to read the file in chuncks the web app need to be connected to the DB with integrated security and this does not work for me.

I forget to mention this, but I would like to read/write the file from/into the filesystem trhough SQL SERVER. Not use share folders or ftp servers and http servers from where I can request the file. I don't know if this is possible.
A friend of mine mentioned that creating a SQL SERVER DATABASE PROJECT in Visual Studio you can perform I/O operations in the SQL SERVER file system and read the file. I have not digged into this at all.

The applications are connected to two possible versions of SQL SERVER, 2012 or 2008.
Sorry for my English, my mother tongue is Spanish.
Waiting for suggestion. Thank you in advanced.

Azure DB User defined assembly support

I get this when trying to port an existing DB to Azure DB

Assembly 'xxxxx' cannot be loaded because Azure SQL Database does not support user-defined assemblies. Contact Azure Technical Support if you have questions.

Is this something that's going to be supported in the (near) future or something that can be enabled per subscription?

Thanks

Issue with CLR Procs

Hello All

We have a CLR procedure for converting names into meaningful names. This procedure actually calls a third party DLL. Names are input to this DLL and correct names are spitted out and later the tables are getting updated. Multiple users are using this CLR procedure and it is being called from UI.

No errors being logged at system level. When component will not work, tables are being updated with some default value. What would be the best solution to track the issue?


Request for SCOM reports already been requested.

best regards,

CLR Runtime error framework 3.5 - System.Security.HostProtectionException

Hi all,

I´ve created a CLR Runtime dll following the steps of this post - https://social.msdn.microsoft.com/Forums/sqlserver/en-US/b732a134-33ba-4880-838d-33fb93887d12/decript-data-on-field-level-that-was-encrypted-on-an-oracle-system?forum=transactsql

It was created for SQL Server 2012 and it works perfectly.

The problem is that the client database is SQL Server 2008 and a new project had to be created for due to the framework 3.5.

So a new dll was created and when I call it on SQL Server 2008 I´m having the following error message.

Msg 6522, Level 16, State 2, Line 1

A .NET Framework error occurred during execution of user-defined routine or aggregate "DecryptDataDecimal":

System.Security.HostProtectionException: Attempted to perform an operation that was forbidden by the CLR host.

The protected resources (only available with full trust) were: All

The demanded resources were: MayLeakOnAbort

System.Security.HostProtectionException:

   en UserDefinedFunctions.Decrypt_AES(Byte[] cypherText, Byte[] Key, Byte[] IV)

   en UserDefinedFunctions.DecryptDataDecimal(String EncryptedData)

Any idea?

Thanks in advance

Can a CLR SQLFunction use a SqlUserDefinedType (table) as an input parameter?

Hi,

I have been unable to find a definitive answer if a sqlfunction can\cannot use a sqlUserDefinedType in the same class. The type is a table struct. It wont compile as the script generated results in the user type being removed with 'unsupported'. I may be missing the obvious. Any guidance appreciated.

public partial class UserDefinedFunctions
{

    [Serializable()]
    [SqlUserDefinedType(Format.UserDefined)]
    public struct ProductData : INullable
    {
        private Int32 id;
        private Int32 productID;
        private Int32 productVersionID;

.etc

.


    [SqlFunction(FillRowMethodName = "OrderTaxCalculationRow", TableDefinition = @" 
                                                                                   [TaxValue] Money NULL,

Hi, I am using SQL Server 2014 and working on writing a clr function which would accept the table name as input instead of dbTable.Name. Please help me rewrite this.

foreach (Table dbTable in DB.Tables)

string pattern = 'Dim_LookupTable_'

                Match match = Regex.Match(dbTable.Name, pattern, RegexOptions.IgnoreCase); //pass table name as parameter instead of dbTable.Name

Would be possible to use something like SQLTriggers (in c#) for catch query events?

Sqltriggers allows INSERT, UPDATE & DELETE events. If possible, how could I know when a table is queried? My need is to execute custom code when this occurs.

I loaded the Reliability Rollup for .NET last night and it seems to have broken my CLR function.

I tried to recompile the DLL on my Windows 10 machine and then load it into my server but it started throwing a new error that it could not reference System.Web and asked me to load it into the database.

I added the following line into my deployment script:

CREATE ASSEMBLY [System.Web] from 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Web.dll' WITH PERMISSION_SET = UNSAFE;

But this is just throwing the following errors:

Please load the referenced assembly into the current database and retry your request.

I have noticed that the Digital Signature of System.Web.dll is different between my Windows 10 machine and my Windows Server 2012 R2.  The server has a new certificate on it with an August Date and my Windows 10 machine has a June date for its certificate. 

Do I need to recompile this DLL on a Windows Server 2012 R2 machine that has the same signature as my production SQL machine or is there some way to update .NET on my Windows 10 machine to have the same digital signature as the server?  I have all the latest patches and updates but do not see anything about the Reliability Rollup for Windows 10.

I think I've found bits and parts of how to do but I must be missing something.  I've not tired it yet, but have just started looking up information.

Hi,

I am looking for compatibility of SQL Server 2012 with .Net Framework 4.6.1.

Does SQL server 2012 work fine with .Net Framework 4.6.1 or do I need to have only 4.0?

All of our servers need to be upgraded to .Net Framework 4.6.1 on mandatory basis and wanted to check whether SQL server 2012 is supported with framework 4.6.1 or not

Already I have explored msdn link for "Hardware and Software Requirements for Installing SQL Server 2012" but didn't get much clarity on the query. Looking for the proofs(links) that say it is compatible.

Your help is much appreciated.

Thank you,

Handling exceptions from stored procedure using Raiserror

I thought it would be very easy to handle the errors thrown from SQL Server stored procedures.
Here is my sample stored procedure:
USE [mydb1]
GO

/****** Object:  StoredProcedure [dbo].[uspTest]    Script Date: 10/25/2009 00:51:47 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[uspTest]
AS
BEGIN
    BEGIN TRY
    --Do something that might cause an error such as SELECT 1/0
     select 1/0
    END TRY
BEGIN CATCH
    ---EXEC dbo.uspRethrowError
    RAISERROR ( 'ERROR occurred',16,1)
END CATCH
end;
GO

Here is

 my VB.NET code

        Try
            cn.Open()
            cmd.Connection = cn
            cmd.CommandText = "uspTest"
            cmd.CommandType = CommandType.StoredProcedure
            rdr = cmd.ExecuteReader()

        Catch ex As SqlException
            logger.Error("SQL Exception : " & ex.ToString)
       
        Finally
            cn.Close()

If I execute the stored procedure from MS SSMS, I see the error on the console. But when I execute from the vb.net code it does not work and the error could not be trapped. The code skips the Catch Block. Not sure why? I have searched all possible documentation on NET and could not figure out. Can any one help, the sooner the better. Thanks

How to share a LocalDB 2016 instance programmatically

I am invoking the SqlLocalDB.exe utility as a process from a Visual Studio .NET application to create and start a LocalDB instance.  That all works fine; however, when I try to share it, I get an error saying this requires an administrator.  Since the user is the administrator, I assume this requires an elevated command.  I've researched this online and the solutions either require embedding an administrator account and password (which is not feasible since this is a distributed app), or setting a 'runas' verb, which appears to do nothing.

I need this process to be transparent to the user (at worst, a UAC prompt).  How can this be done?

Disable manual editing of data in Microsoft SQL Server

I am using Microsoft SQL Server. As you know, edit the data in the database either manually by the original environment using SQL Server user sa or any user of other authorized and also through programming environment that connect to SQL Server to edit the data. Is there a way to disable this editing of data in the SQL Server environment so there is no person in the database manually does not change?

No users even through mssql unable to make changes in the original data. For example, to manually stock the number to another number that this event would not have realized how to change.

can SINGLE_USER help?
Can wizard sql manager for remote did not open ?
Who does not have access to sql server console? And changes only through a interface software or Command Line in master database server operating system?

I think that best way is "database only is edited by sa when connect directly to server and use command for edit database on shell environment and nobody cannot remotely edit it, i means dont connect console "ssms" remotely."
