Mar 7, 2008hello all,
mates i have in my care around 10 applications. each application has it's own database and in each database i have a users table. in these tables i am also having columns for users rights for the applications.
since the users are the same for all 10 applications i am beginning to feel that it's time for a change. i am trying to develop a single database for users but i did not find an appropriate solution for the users rights management. i am afraid that if i put together too many columns in a single table it will decrease performance.
do you know any pattern / article / book for a users management system?
thanks in advance,

System Tables, Dynamic Management Views: Confused
Feb 4, 2008As im diving into my new DBA role and reading as much as I can, I am a little confused on DMV's and system tables.
I've been reading through the book "SQL Server 2005 Bible", which has been very helpful. I tend to use it in conjunction with BOL whenever I come across something I want to learn more.
Last Friday, I tinkered around with DMV's, which was really cool, but I ran into something today that confused me.
Basically, it was finding out the recovery model for all the DB's on the server. The code in the book was:
SELECT [name], recovery_model_desc
FROM sys.databases;
Which turned exactly what it says it will.
however, I am confused.
I initially thought I needed to specify something in the "[name]" section, but realized, that is not the case.
My question is, why is that?
How do I know when to use [] around something?
I found this article:
http://www.databasejournal.com/features/mssql/article.php/3587906
I have been reading it.
I guess I am just really young and raw to T-SQL to know when to use the language corectly.
Is it due to the fact that the rules or syntax is a little different when using system tables?
Hope that makes sense.
Thanks.

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

System.Security.SecurityException: Request For The Permission Of Type 'System.Data.SqlClient.SqlClientPermission, System.Data
Aug 21, 2006I have created a windows library control that accesses a local sql database
I tried the following strings for connecting

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

the error

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?

SQL Server Management Express Studio Management Tools
Apr 5, 2007
I have recently installed the SQL Server Management Studio Express but I do not find Management Tools in order to create scheduled backups and shrinking of the databases. I was under the impression that this should be included in the Management Studio. I use the SQL 2005 Express for smaller customers who run the SQL on a desktop unit. I need a way to backup the data to a server machine for backup purposes. I have uninstalled and reinstalled to no avail.

Sql Server 2005 Operating System Compatibility Warning Message In System Configuration Check
Apr 3, 2007Ok guys, I am trying to install Sql server 2005 on Vista but I am still stuck with this warning message in the System Configuration Check during Sql server 2K5 installation :
SQL Server Edition Operating System Compatibility (Warning)
Messages
* SQL Server Edition Operating System Compatibility
* Some components of this edition of SQL Server are not supported on this operating system. For details, see 'Hardware and Software Requirements for Installing SQL Server 2005' in Microsoft SQL Server Books Online.
Now, I know I need to install SP2 but how the hell I am going to install SP2 if Sql server 2005 doesn't install any of the components including Sql server Database services, Analysus services, Reporting integration services( only the workstation component is available for installation)?
Any work around for this issue?
P.S.: I didn't install VS.NET 2005 yet, can this solve the problem?
Thanks.

Determining What Are System Objects In Sp_help Or System Tables
Jul 20, 2005Hi,I have a few things on my databases which seem to be neither true systemobjects or user objects - notably a table called 'dtproperties' (createdby Enterprise manager as I understand, relating to relationship graphingor something) and some stored procs begining with "dt_" (some kind ofsource control stuff, possible visual studio related). These show up whenI use"exec sp_help 'databaseName'"but not in Ent. Mgr. or in Query Analyzer's object browser, and also notin a third party tool I use called AdeptSQL. I am wondering how thosetools know to differentiate between these types of quasi-system objects,and my real user data. (This is for the purpose of a customized schemagenerator I am writing). I'd prefer to determine this info with systemstored procs (ie sp_help, sp_helptex, sp_...etc) but will dip into thesystem tables if needed.Thanks,Dave

Unable To Cast Object Of Type 'System.DBNull' To Type 'System.Byte[]'.
Aug 13, 2007Hi,
I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ?
Thanks a lot in advance.

View 3 Replies View RelatedPeer To Peer Replication - Quiescing A System ( Quiesce A System )
Oct 23, 2007
MS documentation is short when it comes to explanation of Quiescing a system for peer to peer replication. It seems that for any change the whole p2p machine has to stop ? This would cripple our development/releases... Is it really the case ?
Can all p2p nodes be quiesced except one, the one when I would also make changes ?
i.e. N1 <> N2 <> N3 I would stop inserts/updates/deletes for N1 & N3 and keep inserting/updating/deleting for N2 as I'm making schema change on N2 (additional table, additional field etc). Would it work ?
Also, would I need to stop selects for N1 & N2 ?
Thank you.
'((System.Exception)($exception)).Message' Threw An Exception Of Type 'System.NotSupportedException'
Jan 16, 2008Greetings everyone, I am attempting to build my first application using Microsofts Sql databases. It is a Windows Mobile application so I am using Sql Server Compact 3.5 with Visual Studio 2008 Beta 2. When I try and insert a new row into one of my tables, the app throws the error message shown in the title of this topic.
'((System.Exception)($exception)).Message' threw an exception of type 'System.NotSupportedException'
My table has 4 columns (i have since changed my FavoriteAccount datatype from bit to Integer)
http://i85.photobucket.com/albums/k71/Scionwest/table.jpg
Account type will either be "Checking" or "Savings" when a new row is added, the user will select what they want from a combo box.
Next is a snap shot of my startup form.
http://i85.photobucket.com/albums/k71/Scionwest/form.jpg
Where it says "Favorite Account: None" in the top panel, I am using a link label. When a user clicks "None" it will go to a account creation wizard, and set the first account as it's primary/favorite. As more accounts are added the user can select which will be his/her primary/favorite. For now I am just creating a sample account when the label is clicked in an attempt to get something working. Below is the code used.
private void lnkFavoriteAccount_Click(object sender, EventArgs e)
{
FinancesDataSet.BankAccountRow account = this.financesDataSet.BankAccount.NewBankAccountRow();
account.Name = "MyBank Checking Account";
account.AccountType = "Checking";
account.Balance = Convert.ToDecimal("15.03");
account.FavoriteAccount = 1;//datatype is an integer, I have changed it since I took the screenshot.
financesDataSet.BankAccount.Rows.Add(account);
//The next three lines where added while I was trying to get this to work.
//I don't know if I really need them or not, I receive the error regardless if these are here or not.
this.bankAccountTableAdapter1.Update(financesDataSet);
this.financesDataSet.AcceptChanges();
refreshDatabase();
}
the refreshDatabase() code is here:
private void refreshDatabase()
{
this.bankAccountTableAdapter1.Fill(this.financesDataSet.BankAccount);
//Aquire a count of accounts the user has
int numAccounts = financesDataSet.BankAccount.Count;
//Loop through each account and see which one is the primary.
for (int num = 0; num != numAccounts; num++)
{
//Works ok in frmMain_Load, but when my lnkFavoriteAccount_click calls this, it throws the error.
if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)
{
//Display the primary account on our home page. User can click the link label & be taken to their account register.
this.lnkFavoriteAccount.Text = this.financesDataSet.BankAccount[num].Name.ToString();
this.lnkFavoriteFunds.Text = this.financesDataSet.BankAccount[num].Balance.ToString();
break;
}
}
}
and my form_load code
private void frmMain_Load(object sender, EventArgs e)
{
refreshDatabase();
}
So, when I click on the lnkFavoriteAccount label, and my new row gets added, the app stops at the following line in my DataSet.Designer
[global:ystem.Diagnostics.DebuggerNonUserCodeAttribute()]
public byte FavoriteAccount {
get {
try {
return ((byte)(this[this.tableBankAccount.FavoriteAccountColumn]));
}
catch (global:ystem.InvalidCastException e) {
//Stops at the following line, this error was caused by 'if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)'
throw new global:ystem.Data.StrongTypingException("The value for column 'FavoriteAccount' in table 'BankAccount' is DBNull.", e);
}
}
set {
this[this.tableBankAccount.FavoriteAccountColumn] = value;
}
}
I have no idea what I am doing wrong, all of the code I used I retreived from Microsofts help documentation included with VS2008. I have tried used my TableAdapter.Insert() method and it still failed when it got to
if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)
in my refreshDatabase() method it still failed.
When I look, the data has been added into the database, it's just when I try to retreive it now, it bails on me. Am I retreiving the information wrong?
Thanks for any help you guys can offer.

this.Variables.ObjVariable this objVariables i have create in variable place below like this
Name:Variable datatype int32 values 0
Name: NumberofRowsdatatype int32 values 10000
Name: ObjVariable datatype Object
My code
public override void CreateNewOutputRows()
{
/*
Add rows by calling the AddRow method on the member variable named "<Output Name>Buffer".
For example, call MyOutputBuffer.AddRow() if your output was named "MyOutput".
*/
System.Data.OleDb.OleDbDataAdapter oLead = new System.Data.OleDb.OleDbDataAdapter();
//System.Data.Odbc.OdbcDataAdapter oLead = new System.Data.Odbc.OdbcDataAdapter();
//SqlDataAdapter oLead = new SqlDataAdapter();
System.Data.DataTable dt = new System.Data.DataTable();
DataSet ds = (DataSet)this.Variables.ObjVariable; // here i am getting error
ds.Tables.Add(dt);
ADODB.Record rs = new ADODB.Record();
oLead.Fill(ds, rs, "Variables");
foreach (DataRow row in dt.Rows)

SSIS System Variable ErrorDescription (@[System::ErrorDescription])
Sep 30, 2006Hello,
Does anybody could help me to fixe this query, inside SQL Task to handle OnError event.
The function DT_TEXT does not work with this query and I need to convert the Error Message so that the french caracter ' can be accepted inside the Insert Query.
Here is my query :
"INSERT INTO LOG(EventType, PackageName, TaskName, EventCode, EventDescription, PackageDuration, ContainerDuration,InsertCount, Host) VALUES ('OnError', ' " + @[System::PackageName] + "', '"+ @[System::SourceName] + "', 0, '"+ (DT_TEXT)@[System::ErrorDescription] + "', 0, 0, 0, 'Toto'
)"
The error message is capted inside the Insert Query, for example,
the value of the variable ErrorDescription is : 'Erreur dans l'insertion ' with a quote inside, and therfore the Insert Query can not be executed.
Thank you for helping me to fixe this query !
