SQL Server 2000 To SQL Server 2005 - Any Changes Required To Existing Code, System.Data.SqlClient.SqlConnection?

Dec 13, 2007

My web project (ASP.NET 2.0 / C#) runs against sql server 2000 and uses the System.Data.SqlClient.using System.Data.SqlClient;
 I use System.Data.SqlClient.SqlConnection and System.Data.SqlClient.SqlCommand to make the connections to the database and do selects and updates.  Is it correct to continue to use these against SQL Server 2005?  I ask because I made a connection string (outside of .Net) for SqlServer 2005 using the SQL native provider and it had the following - Provider=SQLNCLI.1 and any connection strings I had made (also outside of ASP.NET) fro SQL Server all used Provider=SQLOLEDB.1.  This is why I wondered if there is a different SqlClient in .Net 2.0 for SQL Server 2005?
Cheers
Al

System.Security.SecurityException: Request For The Permission Of Type 'System.Data.SqlClient.SqlClientPermission, System.Data

Aug 21, 2006

I have created a windows library control that accesses a local sql database

I tried the following strings for connecting

Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"

Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"



I am not running the webpage in a virtual directory but in

C:Inetpubwwwrootusercontrol

and I have a simple index.html that tries to read from an sql db but throws

the error

System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)
at System.Security.PermissionSet.Demand()
at System.Data.Common.DbConnectionOptions.DemandPermission()
at System.Data.SqlClient.SqlConnection.PermissionDemand()
at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,

etc etc

The action that failed was:
Demand
The type of the first permission that failed was:
System.Data.SqlClient.SqlClientPermission
The Zone of the assembly that failed was:
Trusted


I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security

I think that a windows form connecting to a sql database running in a webpage should be simple

to configure what am I missing?

Request For The Permission Of Type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, Pu

Mar 12, 2008


I created a .net console application within which I connect to a sql server (not local) as follows,


string conn_str = "Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=QuantEquitySql;Data Source=server name";

SqlConnection conn = new SqlConnection(conn_str);

conn.Open();
.
Everything works fine when I run it from my computer. When I try to run it from a network share I get the following error,

Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I am using Visual Studio 2005 and .Net framwork v2.0.50727.

Does anybody know a fix to this problem?

Thanks

Why do i get the error message ?, is this related to Code Access Security issues with .net framework. if yes

how do i set the Security so the report server or report manager allows embedded custom code to be executed. Any advice ?

SQL SERVER 2005 + ASP.NET 2.0: Problems With Data.SqlClient.SqlConnection --&> Login Failed For User 'username'

Apr 23, 2007

I have lots of problems with the connection. I've connected many dropdownlists to the database and i didn't have problems at all. I also try an example of an ASP.NET book:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString= "<%$ ConnectionStrings:CIPPEC%>"
InsertCommand=
"INSERT INTO
[member] ([first_name], [last_name], [malefemale], [yearborn])
VALUES
(@first_name, @last_name, @malefemale, @yearborn)">
<InsertParameters>
<asp:FormParameter Name="first_name" Type="String"
FormField="FirstTextBox" />
<asp:FormParameter Name="last_name" Type="String"
FormField="LastTextbox"/>
<asp:FormParameter Name="malefemale" Type="Int32"
FormField="MFRadioButton" />
<asp:FormParameter Name="yearborn" Type="Int32"
FormField="YearDropDown" />
</InsertParameters>
</asp:SqlDataSource>
And it worked well.  But when i try to connect my page with:
Dim connect As New Data.SqlClient.SqlConnection( _
"Server=glgrand-arSQLEXPRESS;UID="WindowsStartupUser";password="WindowsStartupPass"; database=CIPPEC")
connect.Open()
Dim cmd As New Data.SqlClient.SqlCommand( _
"INSERT PRUEBA (PersonaJuridica, NombreRazonSocial, Nombre, Segundo_nombre, Apellido) " & _
"VALUES (txtPerJur, txtRazSoc, txtName, txtSecondName, txtApellido)", _
connect)
cmd.ExecuteNonQuery()
connect.Close()
The error message says: Login failed for user 'username'.
I tried lots of things but it didn't work:
In SQL Configuration Manager:
Client Protocols: TCP/IP and Named Pipes are enabled.
In SQL 2005 Services: Server Properties: Built-in Account: Local System
SQL Server Surface Area Configuration: Remote connections: Using both TCP/IP and Name Pipes connection is selected.
In SQL Management Studio i created a new login glgrand-ar/UserStartupName , with sysadmin server role and user mapping my CIPPEC database.
I don't know what else i could try, i tried it at home and at work and i couldn't connect to my database and make an INSERT. It stops at Connect.Open() with the error that i wrote in this subject message.
It's evident that i'm doing something wrong (because i'm new): Could you please help me with a solution and explain me what are the data that i have to put on the Data.SqlClient.SqlConnection ?? I'm using the Windows authentication: i'm putting my username and password and it doesn't worked.
Thank you!!

System.Data.SqlClient.SqlException: Error Converting Data Type Numeric To Decimal.

Aug 31, 2004

Hi There,

I'm using C# to get a value for a DOUBLE precision variable, called "Length", from a textBox using the following line:

Length = Convert.ToDouble( txtLength.Text )

I'm also using the following lines to prepare my stored procedure call:

arParms[9] = new SqlParameter("@Length", SqlDbType.Decimal, 5);
arParms[9].Value = record.Length;

My stored procedure has the following parameter definition:

@Length decimal(9,3)

My problem is that if someone types a value bigger than 999999 in the textbox he will get for sure the following error:

System.Data.SqlClient.SqlException: Error converting data type numeric to decimal.

I don't know how to either make sql or C# to truncate the value or catch the exception to automatically assign 0 to the parameter.

Please Help.

System.Data.SqlClient.SqlException - When Inserting Image

Jul 13, 2006

Hi All,
I have a form (asp website with the default.aspx and default.aspx.cs) which I use to connect to the SQL Server 2005 database and insert, update,get and delete data to and from it. In the table I have a column called Picture to insert a photo (usually bmp files) which I declared as a varbinary(max). ID is the primary key and is an int (i tried it to be numeric & varchar).
I am trying to insert data into the table using a form with this syntax:
SqlConnection enter_conn = new SqlConnection("user id=;" +
"password=;server=servername;" +
"Trusted_Connection=yes;" +
"database=Member Profiles; " +
"connection timeout=30");
enter_conn.Open();
string insertSql = "Insert dbo.Details(ID,Last_Name,First_Name,Middle_Initial,Project, Organization,Manager,Current_Skills,Biography,Hobbies, Picture) Select 1001, 'ABC','XYZ','R',' Website Development','ACT',LKM','ASP.Net, C#.Net, SQL Server 2005, SharePoint, Java, ',' developing the new website for ACT using SharePoint and SQL Server 2005', ' Singing, Listening to Music, Dancing, Cooking, Swimming', BulkColumn from Openrowset( Bulk 'C:\photos\rose.bmp', Single_Blob) as Picture";


SqlCommand myCommand = new SqlCommand(insertSql, enter_conn);

I rebuilt the table and the owner is now dbo
Here is the Code 
   Function GetCustomers() As System.Data.DataSet        Dim connectionString As String = Application("HiddenConnection")        Dim dbConnection As System.Data.IDbConnection = New System.Data.SqlClient.SqlConnection(connectionString)
        Dim queryString As String = "SELECT [RacingHeritage].[RHID], [RacingHeritage].[UserID], [RacingHeritage].[Clie"& _            "ntFirstName] FROM [RacingHeritage]"        Dim dbCommand As System.Data.IDbCommand = New System.Data.SqlClient.SqlCommand        dbCommand.CommandText = queryString        dbCommand.Connection = dbConnection
        Dim dataAdapter As System.Data.IDbDataAdapter = New System.Data.SqlClient.SqlDataAdapter        dataAdapter.SelectCommand = dbCommand        Dim dataSet As System.Data.DataSet = New System.Data.DataSet        dataAdapter.Fill(dataSet)

Is System.Data.SqlClient Still The Default Provider For The SqlDataSource?

Mar 18, 2008

While learning ASP.net 2.0, I was taught that the the default provider for the SqlDataSource was System.Data.SqlClient, and that I only needed to specify it as a provider when I put it in the web.config file. However, now (in VWDE 2008) when I add a SqlDataSource to a page, it adds ProviderName="System.Data.SqlClient". Does this mean that it isnt the default anymore?

When To Code 'providerName=System.Data.SqlClient In ConnectionStrings, Or Not To?

May 31, 2008

Yesterday, in response to an error msg (something like Login failed for user ''), I deleted the 'providerName=System.Data.SqlClient'in my connectionStrings from Web.config.  Then the aspx website worked.I understand that the value "System.Data.SqlClient" specifies that ASP.NET should
use the ADO.NET provider System.Data.SqlClient
when making a connection.  Why deleting providerName solved the error?  Jeffrey

System.Data.SqlClient.SqlException: Timeout Expired.

Dec 3, 2007

We have some big problems with our SQL Server 2000 database right now.
The code has not been changed for over halv an year and some days ago we started to get this error.





System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Both web and database server is running fine.
Any help is appreciated!

(We are now pretty sure that all errors occurs when we are doing inserts to the database.)

System.Data.SqlClient.SqlException: Timeout Expired.

Jul 21, 2007

Hi there,



I am not sure it is the right forum. The Exception is thrown in C# app while saving a few databases. Small databases are being saved OK but this one has 12,934,142KB after the last backup. I am not even sure what the words "last backup" mean in this case. It is possible that is the size of the database from two months ago when first the problem appeared. Since then I've neglected backup being preoccupied with other problems although the database grew.



The backup is executed by this store procedure:

USE [hist_OHLC]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER OFF
GO

ALTER PROCEDURE [dbo].[backUphist_OHLC]
AS
BEGIN
SET NOCOUNT ON;
ALTER DATABASE hist_OHLC SET RECOVERY FULL
BACKUP DATABASE hist_OHLC TO DISK = 'L:SQLServerBackupshist_OHLChist_OHLCFullRM.bak'
BACKUP LOG hist_OHLC TO DISK = 'L:SQLServerBackupshist_OHLChist_OHLCFullRM.log';
END


What can I do about it? What is the rational way of backing up databases of this size?



What is the rational way of maintaining databases of this size in SQLEXPRESS? Shall I perhaps break this database down into fragments?



The tables contain daily records, about 500 per day. I can conceivably create another database every month or so but it will be a hassle.



How can I increase the timeout?



I just repeated the backup. All databases have been saved except this last one--Imoved that backup operation down the chain to be the last one. One database with about 1.5GBytes was saved fine.



I checked the timeout it is 15 sec. One has not control over it in C#. It does not have a Set option.



15

MyHandler caught : Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

The backup or restore was aborted.



Thanks.

System.Data.SqlClient.SqlException: Timeout Expired

Sep 26, 2007

Hello, we have a fairly large .NET application that uses MSSQL Server 2005 Express.

I am getting the following error loggged to our error log somewhat often:

System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

IIS and MSSQL server are on the same box, and talk locally. The server box is NOT losing internet so that is not the problem.

What could be causing this? Is this because we don't have enough system resources on the server, meaning CPU, RAM? Or is it poorly written ASP.NET or missing configuration information in the web.config file?

Thanks for the insight.
