Hi Guys!
Am at my wits end! Please help me with any suggestions.
I have recently created a website for my father's Driving School which has database properties built in. I created it using Visual Web Developer 2008 and am now trying to make it possible for his clients to view any lesson dates and times of future lessons. Each client has their own username and password to access their own user area on the site. Obviously I want each client to be able to see their own times but not those of other clients. My father will be inputting the dates and times of all clients lessons himself.
How would I best go about this? My father is fairly IT literate, but would like all dates and times in a central database if possible. Please help. Many thanks.

Well, when your father saves the dates and times into the database, have him select a client from a dropdown list (so that he selects a valid client), then when your clients log into the system, store their ClientID in the session state or similar, and when selecting values from your database for lessons, restrict it by ClientID.
eg:
select LessonDate, LessonTime from tblLesson where ClientID = @ClientID
populating @ClientID with the ClientID of the logged in user.

This is my stored procedure
ALTER PROCEDURE TeamStructure
(
@rootid int
)
AS
WITH MyTeam
AS
(
SELECT *, [Name] AS ParentName, 0 AS TeamLevel FROM tbl_team
WHERE ParentID =@rootid UNION ALL
SELECT Fam.*,MyTeam.Name AS ParentName, TeamLevel + 1 FROM tbl_team AS Fam
INNER JOIN MyTeam ON Fam.ParentID = MyTeam.ID)
SELECT * FROM MyTeam
It will return the complete hierarchical records.
Level 0 will have root member
Level 1 will have 2 members
Level 2 willhave 4 members
Level 3 will have 8 members
or if level =n
members= 2^n
I need to perform the following operation:
for any level if members are less than 2^n the iteration should stop and return the number of members on that level and the number of level
For example if the number of members on level 4 are 12
The procedure should stop and return
level :4
Members :12
but if the number of members on nth level is exactly 2^n the iteration must look for the next level
Can anyone modify this procedure and help me please?
TIA

I have a Questions table in my database where the quuestiions are selected randomly using the following code
"public DataTable getQuestion(string concept,string questiontype)
{//gives the user the question for the concept selected above
string sql = "";
if (concept == "basic")
{
sql = "SELECT Question FROM Questions WHERE ConceptId LIKE 'BC%'AND QuestionType ='" + questiontype + "' Order by NewId()";
}
else if (Concept == "programming")
{
sql = "SELECT Question FROM Questions WHERE ConceptId LIKE 'PC%'AND QuestionType ='" + questiontype + "'Order by NewId()";
}
return dc.load(sql);//dc is an object of data connection class
}
Another question type is of multiple choice.And for this type of question there's an Options Table which I need to get the options of the question selected randomly using the code above. Any idea how I can do that? Please help.

Good day LucBite
Can you explain Briefly what is your Problem. i understand what you are trying to do, but can you tell us what exactly is your problem

How do I select the options of a multiple choice question, for the multiple choice question that I selected randomly. Remember, I can't select the options randomly because they have to match the question even though the questiion is selected randomly. The questions are from the Questions Table and the options are from the Options Table. I hope I'm clear please help.

Good day LucBite
You did Explain Clearly again so that i cannot understand better, remember you showed us a Function that return a datatable, now when i said explain clearly i mean to tell us where does the parameters get passed from(UI or Another Function). I Assume you are trying to do something like this
You have a Testing Application, First you have Different type of Test "Basic", "Programming" and "MultipleChoice"
Now you can select Randomly for "Basic" and "Programming" But you cannot select Randomly for "MultipleChoice" So you want it to be able to select for "MultipleChoice" Questions Randomly"
This is how i understand it ,before i give you a solution , i would like to if am right else explain more give me more info

So, for a multiple choice question type you want to return random questions and, for each of the questions returned, the applicable options?
If I were you, I'd change your sql to return 2 columns for multiple choice, the question text and the id (the primary key on the question table). From there, you can select the options from the appropriate table using the id of the question.

I'm not absolutely sure I understand your question, but this is what I think you might be asking for:
class SwitchTest
{
static void Main()
{
Console.WriteLine("Coffee sizes: 1=Small 2=Medium 3=Large");
Console.Write("Please enter your selection: ");
string s = Console.ReadLine();
int n = int.Parse(s);
int cost = 0;
switch(n)
{
case 1:
cost += 25;
break;
case 2:
cost += 25;
goto case 1;
case 3:
cost += 50;
goto case 1;
default:
Console.WriteLine("Invalid selection. Please select 1, 2, or 3.");
break;
}
if (cost != 0)
{
Console.WriteLine("Please insert {0} cents.", cost);
}
Console.WriteLine("Thank you for your business.");
}
}

I’m practicing a database and I have a 3-column table. I’m using binary formatting to save/open the file. I can’t see what is wrong with my code –
I can display records in the datagrid view ok when I press the save button
I can also save the records into the dataset ok when the save/close button is pressed.
When I reopen the programme and press the reload button to reload the dataset, additional records will not be displayed nor saved though original records will be showing in the datagrid.
When I reopen the programme and DO NOT press the reload button, I can enter new records and they will be saved because this is basically overwrites the original dataset.
Ideally, I want to be able to open the dataset and then be able to add new records to the dataset/datatable.
Any help and advice on how to correct this?
Thanks,
Steve

I'm running sqlpubWiz from the command line to script my database. This command line worked with SQL 2005 - I have changed to 2008 and have got the latest version of SqlPubWiz (as far as I know - it's in the folder C:\Program Files\Microsoft SQL Server\90\Tools\Publishing\1.2
I run sqlpubwiz script -d mydatabsename-S localhost\mydatabase -f test.sql -targetserver 2008
All looks well - it starts with "Gathering List of Objects to Script" then changes to "Scripting Objects" and starts printing dots to show progress... then stops with
Error: Operation is not valid due to the current state of the object.
Funny thing is that it works fine if run through the GUI.
I'm all out of ideas.....

My Client will place inputs files in psftp. we need to write a procedure in sql server 2005, which has to periodically check the psftp for files if any files found in psftp then the sql procedure has to download those files to local folder.
Actually i have written a batch file which login to psftp and download the files to local folder. if i run the batch file manually the batch file download files from PSFTP to local folder, but if i execute the same batch file in management studio its showing as executing but its not doing anything and after some seconds management studio is not responding.
if anybody can tell me how to do this it will be great help for me.
the command i used is
exec master..xp_cmdshell '\\server1\file\download.bat'
Thanks & Regards,

Hello Gurus!
Please can someone help me in the following problem:
Am finding it very difficult connecting to MS sql database hosted on a web server from my machine through a stand alone application i developed.
I have followed this http://support.microsoft.com/kb/914277[^]
To configure both my machine and the Sql Server Management Studio Express, but this error keeps coming up:
"An error has occured while establishing a connection to the server. When connecting to SQL server 2005, this failure may be caused by the fact that under the default settings SQL server does not allow remote connections. (provider: SQL network Interfaces, error : 25 - Connection String is noy valid)"
my connection String looks like below:
"Data Source = https://sbbMedical.com\localhost; Initial Catalog = sbbmhcom_medihealth;Integrated Security=False;User Id= '" & UserIdTextBox.Text & "'; Password= '" &PasswordTextBox.Text &"'"
NOTE: I have for example the database to be sbbmhcom_medihealth, with the password: obisi1 and User id: obisimora. But my domain user ID is "medics" and password is "nevermind"
How do I adjust the connection string.
what am I missing.
Thanks in advance

There are a number of issues with your message, least of which is publishing a username andpassword.
localhost is only a valid name when SQL server is installed on the local machine. Find out the name of the SQL server installed at sbbMedical.

The name of SQL server is windows7\SQLEXPRESS
Any idea?

With this type of String Concatination you will have problems.
Always put your Connection String in your WebConfig
like this
How to Store and Retrieve a ConnectionString from a Web.Config or App.Settings File[^]
Your First part of the Connection string is not Correct.
change your connection string from this
"Data Source = https://sbbMedical.com\localhost; Initial Catalog = sbbmhcom_medihealth;Integrated Security=False;User Id= '" & UserIdTextBox.Text & "'; Password= '" &PasswordTextBox.Text &"'"
to
"Data Source =VUYISWA\SQLEXPRESS; Database= sbbmhcom_medihealth;Integrated Security=False;User Id= '" & UserIdTextBox.Text & "'; Password= '" &PasswordTextBox.Text &"'"
i have change the HTTP to the name of the SQLEXPRESS i have locally on my machine. To know the name of your sql name ,just open management studio and try to connect , use the name displayed on the server name not the http.
Tell me after that if the Error changes
