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.

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 &"'"

"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

Thanks Vuyiswa!

I have tried ur suggestions as follows:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>

    <add key ="MyCon" value ="User id= UserIdTextBox.Text;
    Password=PasswordTextBox.Text;Data Source =mark.internet-webhosting.com\SQLEXPRESS;Trusted_Connection=Yes; Database=sbbmhcom_TESTDB"></add>
    
      </appSettings>

</configuration>

And

Dim str As String = System.Configuration.ConfigurationManager.AppSettings("MyCon")
            'open connection
             myConnection.ConnectionString = (str)
            myConnection.Open()

But with the following error:
login failed for user" . The user is not associated with a trusted SQL server connection.

Do I need to do any further configuration?
And for ur info. my firewall is disabled, I no its not save but this project is my priority at the moment.
Any more advice/suggestions/corrections?
Am just a newbie!!
Thanks for ur time!

Good Morning ChiSmile

in your Server Properties go to Security and make sure that both Windows Authontication and SQL Server Authontication is checked.i think now its only Windows Authontication.

And that will solve your Problem

Thanks

Re: How do i retrieve data from an MS sql database hosted on a web server

14-Jul-09 13:37

Thank Vuyiswa, u are the best! it worked just fine!

But do u know how i can use windows emulator to access the database.
The applications I've written is in VB.net using visual studio professional 2008, one is mobile and the other is desktop.
The application (mobile) should be able to collect data from field work and store it dirctly on the server database while the desktop application should act as the admin to create users and do other admin stuffs.

So any help? I hope this is the right forum for this!!

Anyway, Thanks in advance

How to Filter variables for SP, to return only one value from many in SQL View

I am using Windows XP version 2002, service pack 3.

Re: How to Filter variables for SP, to return only one value from many in SQL View

9-Jul-09 2:00

Hi ,

In a SQL View, I have 5 boolean variables and one int variable.
out of 5 boolean variables only one variable will be true for a single data row,

Task                              Type      boolVerySmall Datestart                           TagName
----------------------------------------------------------------------------------
Architecture Setup -- Doc Code True               1900-01-01 00:00:00.000      Design_09

idProject   boolsmall   boolMedium   boolLarge      boolVeryLarge      intHours
----------------------------------------------------------------------------
4               False            False         False            False                  0

The above data is for one row... in this row, when I download the data from database to excel sheet, I have to display only the value which is true (boolVerySmall ,boolsmall,   boolMedium,boolLarge, boolVeryLarge, intHours) should be displayed in a s ingle column,

I have written a Stored procedure for this. I am finding it difficult to get a particular row which has TRUE of intHours>0.

I am adding the sql query below. Please help me

> SELECT      dbo.tblResourceTaskList.txtTask, dbo.tblIndividualRelativeData.txtProductType, dbo.tblResourceTaskList.boolVerySmall,
dbo.tblResourceTaskList.dtActualCompletionDate, dbo.tblEffortCodes.txtTagName, dbo.tblResourceTaskList.txtTaskNotes, dbo.tblResourceTaskList.idSubProject, dbo.tblResourceTaskList.idLaunch, dbo.tblResourceTaskList.idResource, dbo.tblResourceTaskList.boolSmall, dbo.tblResourceTaskList.boolMedium, dbo.tblResourceTaskList.boolLarge, dbo.tblResourceTaskList.boolVeryLarge,
dbo.tblResourceTaskList.intDirectHours

FROM            dbo.tblResourceTaskList INNER JOIN dbo.tblProjectUsers ON dbo.tblResourceTaskList.idSubProject = dbo.tblProjectUsers.idSubProject AND
dbo.tblResourceTaskList.idResource = dbo.tblProjectUsers.idUser INNER JOIN
dbo.tblLaunchInfo ON dbo.tblResourceTaskList.idLaunch = dbo.tblLaunchInfo.idLaunch INNER JOIN dbo.tblIndividualRelativeData ON dbo.tblResourceTaskList.idIndividualRelativeEffort = dbo.tblIndividualRelativeData.idIndividualRelativeEffort LEFT OUTER JOINdbo.tblEffortCodes ON dbo.tblResourceTaskList.idEffortCode = dbo.tblEffortCodes.idEffortCode

My stored procedure is
SELECT txtTask, txtProductType, **boolVerySmall**, txtTagName, txtTaskNotes,

dtActualCompletionDate
   FROM tblResourceTaskList_View
WHERE (idSubProject = @idSubProjectIndex )

as the first row from db has TRUE for boolVerySmall, then SP should return this value and if its other than that it should give that value.

Instead of filling *True* in excel sheet, I , have to assign VS for boolVerySmall, S - Small, M - Medium, L - Large VL- VeryLarge in the excelsheet.

So please help me how to work on this.
1. Assigning shortnames (like VS... for the bool var's).
2. Returning only one value (boolverysmall or ... ) and assigning VS to that and fill it in excel.
3. if all the bools are false, then intHours should be assinged...

Kindly help me.

Thanks
Ramm

Firstly your data structure *sucks*, you should redesign your table to have 1 column for size and 5 possible values. If possible do this NOW, if you leave it you will continually be plagued by this issue.

In the select part of you query use a nested CASE statement,

Case When size1 is null then 'S' else
   Case when size2 is null then 's1' else
      Case when size3 is null then 's2'
end end end as Size

You get the picture. Fix you structure if at all possible, if you own it then suck it up and make the changes, pay the cost for lousy design NOW, it only gets more expensive the longer you leave it.

Stored Proc Optimisation

Hi All.

I have a stored procedure which returns a set of records. I have an optional parameter in there, so the idea is the proc will return all records if the parameter is null, otherwise filter the results.
Code:

CREATE PROC sp_MyProc (@ItemID AS INT)
AS
BEGIN
   SELECT *
   FROM   myTable
   WHERE  ItemID LIKE CASE WHERE @ItemID IS NULL THEN '%' ELSE '%' + @ItemID END
END

Is there a more effient way of doing this without repeating the query with an IF statement? (My Actual query is quite lengthy, so repeating the code will be messy)

Thanks in advance Big Grin | :-D

oooo, the Jedi's will feel this one....

CREATE PROC sp_MyProc (@ItemID AS INT)
AS
BEGIN
   SELECT *
   FROM   myTable
   WHERE  ItemID=isNull(@ItemID,ItemID)
END

Check out IsNull[^].

It checks whether the parameter is null and in case it finds it to be null, returns back the column queried which indicates an (1=1) condition.

hope the explanation is clear enough.

When you fail to plan, you are planning to fail.

Thats great. Thank you.

Just one question though: If this were to be run against a large table, would the fact that a where clause is included impact the performance? or would the 1=1 condition make it run just as fast as if there were no where clause? Smile | :)

oooo, the Jedi's will feel this one....

I like the ISNULL example above, but I have a feeling it will affect performance - I have reservation as to whether SQL will correctly use indexes when resolving the function call.

Ive always used this method, which I know works:

SELECT *
FROM   myTable
WHERE  @ItemID IS NULL OR ItemId = @ItemId

Also, depending on which version of SQL Server you're using, prefixing your stored proc with sp_ affects performance in that it looks in the master db first. I think you'd have to be using a very old version for this to be true, but its good practice not to use an sp_ prefix - if you really like prefixes use usp_ to distinguish from in-build sp's.
