Hi,
I want to make use of the .NET 2.0 memberships and roles tables in my database.
I'm referring to the following tables (not all is listed):
aspnet_Applications
aspnet_Membership
aspnet_Roles
aspnet_Users
aspnet_UsersInRoles
What is the best possible way of getting these tables in my database? Creating and running the SQL script? And how do I write code to access and modify the contents of these tables?
Is this the best possible way to go about it?
Regards,
ma se

Hi,
The creation of a new login is a bit confusing to me in SQL Server 2005. I usually use username sa and it's password. But now I'm trying to add the DotNetNuke database, with a different login name. They say I must go and create a new login, and a new user. What is the difference btween the 2?
This does not just apply to the DNN database, I want to do the same when adding any other new database.
Please can someone help me with my confusion??
Regards,
ma se

If you do not prefer to use the Enterprise Manager, you can run something like this from the Query Analyzer:
DECLARE @cNewUser VARCHAR(20)<br />
DECLARE @cNewPassword VARCHAR(20)<br />
SELECT @cNewUser = 'MyName'<br />
SELECT @cNewPassword = 'MyPassword'<br />
<br />
EXEC sp_addlogin @cNewUser,@cNewPassword, 'DNN'<br />
<br />
EXEC sp_grantdbaccess @cNewUser

SQL Server has the concept of a login, which is global to a server, and a user, which is specific to a database.
Logins are what get authenticated - you must tell SQL Server either about a Windows username or group, or you must specify a username and password. You can assign fixed server roles to a login (alternatively you can say you make a login a member of a role). These roles control whether a login can create their own databases and various other sorts of administrative rights. You'll find these in Management Studio under Security, Logins.
Users are the same sort of concept within the database itself. A login must be granted access to, and mapped to a user in, a database to be able to access it (unless they're a member of the sysadmin fixed server role). The name of the user in the database can be different from the user's login - normally the database owner's login is given the name dbo within the database. Permissions in a database are assigned to a user or to a role - again, you can make users members of roles to make the permissions easier to manage. Create users in Management Studio by going to Database, Security, Users.
Normally I simply make users members of the public database role then set permissions for that role. I allow Management Studio to add the login to the database by checking the box next to the database in User Mapping in the login's Properties. If you need different permissions for different subsystems - probably a good idea - then create more logins and users.
I'm afraid I don't know much about using application roles. I can see they're there, and I think they would allow you to keep and use a single login but assign different permissions for different applications accessing the same database. For DNN this is almost certainly overkill. It looks like you need to code explicitly to use different application roles (the documentation mentions using sp_setapprole to change to a different role).
Stability. What an interesting concept. -- Chris Maunder

Hi,
I've been googling all day, found info but it still doesn't work
I have a binary field of 50 bytes long. I need to load this from the database and
store it into a byte array in my application VC++ (NO .NET). But it seems I just can't convert the SafeArray data into a BYTE[]. I'm really stuck on this. I am getting despreratly, this shouldn't be this hard so what don't i see.
...
_RecordsetPtr rsFoo;
_variant_t vtHolder;
int iMyID;
BYTE* pMyData = new BYTE[50];
try
{
rsFoo.CreateInstance(__uuidof(Recordset));
rsFoo->Open((_bstr_t)strQuery, GetConnectionPtr().GetInterfacePtr(), adOpenDynamic,adLockReadOnly, adCmdText);
if(rsFoo->adoEOF && rsFoo->BOF)
return;
vtHolder = rsFoo->GetCollect("ID");
if(vtHolder.vt != NULL)
{
iMyId = (int)vtHolder;
}
vtHolder = rsFoo->GetCollect("Data");
if(vtHolder.vt != NULL)
{
....
....
}
}
catch...
codito ergo sum

Hi,
I am trying to set one of my data cloumn to auto-increment but there isn't any option in the column properties to do that. I am using VS 2005 to add column to my database, so can someone point me in the right direction? Thanks! And btw, I looked at some of the help which uses VB codes to set the column datatype and set autoincrement to true and stuff... How do you work those thing? haha.. Sorry no experience in VB.

Hi, I am asked to work on ASP.NET2.0 web development project which is already in development stage. This project development is in ASP.NET2.0 and SQL Express.
I have downloaded the project related files from the server.
I saw few files as having ".dtsx" extenstion. and one script file (text file, consisting a script to create tables.)
I have following questions.
1. What is .dtsx file meant for?
2. How can I run the query to create datatables? I mean here, in SQL 2000, I used query analyzer to execute queries. How can I do it in SQLExpress? Can I execute the query from VS.NET2005?
Please let me know. Thanks in advance.

Hi,
Are there any techniques /rules/measures that should be followed to develop stored procedures so that the efficieny of the appliaiton increases.
Regards,

* Don't use cursors (there cursed)
* Set NoCount off
* have efficient SQL SELECT statements
* Sometimes using temp tables is quicker than complex joins from many tables

You could use the "show plan" in SQL200 or "display estimated execution plan" in SQL2005 to see exactly how costly each process is and maybe modify it accordingly.
Thanks.

I have an ASP datagrid in which the user can look up an existing record and update the fields, or insert a new record. So I have a couple of questions...
1. Is it considered better to delete the old record and insert the new (updated) record? I am rewriting this application and the old programmer did it this way which seemed odd.
2. If it is better to update, how do I program in SQL
if partNumber already exists, update
if PartNumber does not exist, insert
Thanks!

something like this. 0 is default value for PartNumber and if it does not exist than it will be created and a new part number will be returned,
create proc myProc
@PartNumber int = 0,
@PartDesc varchar
AS
Declare @partNo_Used
if @PartNumber = 0
Begin
-- Insert into Table
insert parts ( partdesc ) Values ( @PartDesc)
--- Get identity or part number
Set @partNo_Used = @@Indentity
End
ELSE
Begin
-- Update Record
update parts
SET partdesc = @PartDesc
Where Partnumber = @PartNumber
@partNo_Used = @PartNumber
End
-- Return Part and Desc
SELECT @partNo_Used , @PartDesc
GO

How huge is huge. I've tun dbs upto 10Gb with no real problems. If you want realtime analysis then you have to get inventive with your data design, indexes etc..
you can split tables across databases or even tune your disks and datafiles as well i.e have data and indexes on seperate raid arrays or even have different tables on different drives etc...
This all depends wether its transactions, logging or reporting etc... As Colin said its all realative to your application.

Hi
I'm trying to read RTF and Word files from blob columns in SQL Server, but the files can't be opened in Word when i retreive them. What am I doing wrong?
<br />
FileStream fileStream = new FileStream(filename, FileMode.Create, FileAccess.Write);<br />
BinaryWriter binaryWriter = new BinaryWriter(fileStream);<br />
<br />
long totalBytes = sqlDataReader.GetBytes(blobColumn, 0, null, 0, int.MaxValue);<br />
<br />
byte[] outbyte = new byte[totalBytes];<br />
sqlDataReader.GetBytes(blobColumn, 0, outbyte, 0, (int)totalBytes); <br />
binaryWriter.Write(outbyte, 0, (int)totalBytes);<br />
binaryWriter.Flush();<br />
<br />
binaryWriter.Close();<br />
fileStream.Close();<br />

I have a small access database at whitch I connect through OleDb. Nothing going bad so far.
I use C# for the client, so I connect using OleDBConnections, and querry the database through OleDbDataAdapters.
The problem apears at date/time fields in the database: using the data adapter the fields are revealed to the client as DateTime objects, but at update or insert commands I get an error message informing me that the date argument is mismatched.
After searching the net I found that date/time objects in Access should be passed into update/insert commands like strings between # chars. If I do like this the whole thing is ok, but is there any way that I can make the data adapter work with access?
Thank you.
protected internal static readonly ... and I wish the list could continue ...
