|||Bernard:
It looks like you already have data in those tables, so the easy thing to might to be issue a query on them like this
select * from t1 for xml auto
Then save those results out to file. You'll have to edit out the extra line feeds and add the XML prolog to make that a valid XML file.
Once you have that, and assuming you have the .NET SDK install, you should be able to use XSD.EXE to generate usable schmea.
If you already have the XML files you want to import, you can just feed them to XSD.EXE one at a time to get a matching W3C schema.

If I'm reading this right, he doesn't have any.

HELP with connection string PLEASEEEE!

hi, I'm kind of really new to this. Trying to learn asp.net 2.0. Have been designing a website, and, so far so good, I can deploy the files, but I can't get the synthax right for the connection string. in my web.config file the connection string works on the local computer, but I can't figure out how to change the data source part:
this is what I have in my web convig file
<add name="Database2ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename="C:\Documents and Settings\Alexi\My Documents\Delivery\web\App_Data\Database2.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True"
providerName="System.Data.SqlClient" /
the the wrox book says I have to have the|datadirectory|
does it mean I have to write the full http address on the server?
and I can't figure out what to substitute in for the ".\sqlexpress" part...

my host has ms sql server 2000 and my sql. I asked for their support and the gave me a weird looking connection string and claimed that it worked...

<%@. LANGUAGE = JScript %>
<% var oConn;
oConn = Server.CreateObject("ADODB.Connection");
oConn.Mode = 3
oConn.Open("Provider=SQLOLEDB;Server=203.89.181.78;Database=alexeyka_yah_1951com_;UID=support;PWD=test123;");
%>
'

How can I, and where, copy my existing databse, and change the connection string?

Would really appreciate any help, perhaps buy a new book from the programmers in gratitude.

there is nothing wrong with connection string - the problem is that you are using database file with SQL express and you host SQL 2000 - so they will not be able to attach database file the way SQL Express does...

few days ago i posted why not to use database file with project that will go to shared hosting here:
http://forums.asp.net/thread/1375347.aspx - in the future login to SQL (express is cool) and create database then backup it and restore on your web hosting's SQL server

More info about connection strings you will find here:
http://www.connectionstrings.com/

If the database you have is empty no real data, then copy databse structure to new server change database2ConnectionString and you are good to go

your connections strin g will look like this

BTW if that is real user pwd - CHANGE IT

Hey, thank you so much for you help. Sorry for the late reply - didn't

The database does connect now, so all I have to do now is to figure out how to actually copy my database file to server.

if they offer SQL 2005 you should not have any problems. If not and you have to use SQL 2000 read this:

Hey, thanks again.

I was able to create an identical blank database table on the server in their asp.net enterprise manager. Yes, the do only have 2000 version.

Then, in VWD express I changed datasource control to point to the connection string that connects to the db on the server - it worked.

I'm struggling to contect to the database remotely, will hopefully figure something out.

Cheers again,

Alexi

" I'm struggling to contect to the database remotely " ? - IF the hosting company accepts remote connections you can use free tool like SQL Server Managment Studio Express Edition to connect and work on you database. Keep in mind that many hoster block remote connections so you can only make changes to database design via online Enterprise manager or diffrent tool. If that is the case then simply change connection string in web config when you work on this application to you local machine, and before you do upload to server change it back to real SQL (the 2000 one)

Hi Tom,

Thanks for you reply. I did download the sql server management studio, and asked whether my hosts allowed the remote connection - they don't. so I guess I have to do everything from scratch on the enterprise manager online. I've figured out normal tables, my main concern now will be to generate tables to store username/password info.

Cheers once again,

Alex

Hi Tom,

Thanks again for you input, have been real busy populating my datatables, so haven't had time to work on logins/users. If you like, you can check out the results of your efforts atwww.takeawaydelivery.co.nz

Will now be working my way into creating loging pages. By the way, the link that you gave me for some reason, it says there was a fata error and it couldn't be viewed? Anyway, thanks for all your help, and I'll let you know if I get around to creating users/etc

the one with script or the one with tool to manage users ? i chcecked both links and are working just fine for me.

Hi,

Seems to be working fine now, that was the tool to manage script. Downloaded it, and ran it. Works fine on my computer, though I can't understand though where are the usernames/passwords are stored. Also, with the tables, do I just run the whole script in the enterprise manager? and how do I link the two? Thanks again,

Hi,

an update here - the admin tool works fine on the local computer. I also reconfigured the weg.config file to point towards a remote database for users/passwords:

<membershipdefaultProvider="CustomizedProvider">

<addname="CustomizedProvider"

type="System.Web.Security.SqlMembershipProvider"

connectionStringName="MyDB"

minRequiredPasswordLength="5"

minRequiredNonalphanumericCharacters="0" />

</providers>

</membership>

(and added a corresponding connection string).

For some reason though, when I run the table building script it doesn't show that anything is happening? like tables do not appear? any ideas-

thanks

Help with connecting to SQL database and binding

I am new to .net and I am using Visual Web Developer 2005 Express with SQL Server 2005 Express. What I would like to do is connect to my SQL database (which resides in the app_data folder) and open a table and pull out a field and place it in either a textbox or label on the page. No editing or deleting. Just simple one field binding. By the way, I can do this with all the cool built-in tools of VWD, but I want to know how to do it all by hand. I would really appreciate it if someone could help me out.

When using a data source you need to wrap a formview tag around the label, and bind the formview to the datasource.

Here's some samples of the formview tag:

Help with cascading SELECT

Hello
I have the following scenario that I need to address with which I would
appreciate some help if anyone has the time:
(Simply) I have an asp.net application:
I have 2 tables:
Table 1 is called Categories and is used to hold hierarchical data (Tiers) -
these Tiers can be altered by the users. There may be 10 Categories in Tier
1, Tier 2 will hold 1 or more sub-categories for those 10, Tier 3 will have
sub-categories of Tier 2 etc. etc. through to Tier 5
Table 2 is called Jobs and holds information pertaining to a specific task
that is categorised by Table 1, so this would have single entries that you
should be able to back-track through to Tier 1 of Table 1
This structure is to simply organise data in a highly retrievable structure.
So when a user clicks on a Category in Tier 1 I want to retrieve all Jobs
that are under that category regardless of the sub-category structure
underneath, a click on a category in Tier 2 will filter these, a click on a
sub category in Tier 3 will make the list smaller etc. etc. (I'm sure you ge
t
the picture)
When a category or a job is defined and entered by the user a unique numeric
reference is automatically assigned to that record - it also records the
unique reference of the category above in a field called "Parent_Ref". I
should therefore be able to take the parent record from a Job (which is the
end of the line) and track this back to a sub-category in Tier 3, 4, or 5,
this category record will also have a parent which goes back to Tier 2 and
this will have a recod that tracks back to Tier 1
When the user initially clicks on a Tier 1 Category I need to do a search
for all Table 1 records that have the unique reference of that Tier 1
category in their "Parent_Ref" field.... for all returned records I need to
then do a search through Table 2 for all Jobs that are associated directly
with that category. This will give me 0 to x returns from Jobs. I then need
to requery and find all records from Tier 3 in Table 1 that have one of the
unique references from the Tier 2 records that were just returned in their
"Parent_Ref" field then retrieve all Jobs that relate to these retrieved
records and loop through all the Categories in Table 1 until no more returns
are possible
I hope this is clear !?! I'm sure this is a standard scenario, I have
researched the Select options in transact SQL but can not see the light. I
appreciate that this will probably need to be a stored procedure that will b
e
triggered by my asp.net application where I simply pass the unique ref in to
SQL and let it do the search, but I do not know how to cascade the queries i
n
the above fashion
Thanks

The best way to know would be to test it on your system. It should peform
adequately with several thousands of rows with an average depth of about ten
levels. When I say "adequatly" that does not mean "perfectly". In SQL 2005
the function should be redesigned using a recursive common table expression
(rCTE), which might improve performance, since it's built into the SQL Serve
r
engine and requires less CPU time to execute.

Help with BCP

NOTE: Addresses, usernames, and passwords have been changed.

I am trying to do a Batch Backup of my SQL Server (sql6.alpha.net) to (sql4.alpha.net). So I go onto sql6, get to a dos prompt and type the following (in order to backup the first table, "Accounts").

BCP "AlphaOffice.sa.Accounts" out "AOBackup-Tuesday.Accounts" -S"sql4.alpha.net,10775" -U"username" -P"password"

I get the following Error:

SQLState = 37000, NativeError = 4060
Error = [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database requested in login 'AlphaOffice'. Login fails.

Now - I Know for a fact that the database "AlphaOffice" exists. My question is: the -P and -U parameters are for a username and password. Is this the username/password for the source DB (housed on the computer I am running BCP from), or the username/password for the destination server (Where the backup will eventually be housed)? If I use the User/Pass from the source, I get the above message. If I used the User/Pass of the destination, I get an error which states Access is Denied. Any thought?The -U -P refers to the server you are exporting data from or importing data to. In the example you have listed the -U -P is for sql4.alpha.net. When you bcp data to sql6.alpha.net you will use a uid/pwd for that box. You might also want to through a "-n" to extract the data in native mode.

Having said all that, DTS would be an easier way to go. You could DTS the data out of sql4 and then DTS the data into sql6 or go directly from sql4 to sql6.

btw, the error message you are getting suggests that the DB you are referencing does not exsist rather than a login problem.|||Personally I'd still prefer BCP over DTS (unless it's a Yukon DTS) simply because you can touch and feel the resulting file before you can send it to the destination. The trick there is to know whether the table contains an IDENTITY field on the destination, and if you need to retain the values from the source,- specify -E switch. And you definitely need to include either "-n" or "-c" switch, otherwise the utility would take you through a series of "employment application" type questions and offer to save the answers in a format file before you get to see the actual extraction process.

Is there a way to write an exists to query @.@.Rowcount?What are you querying @.@.ROWCOUNT for? @.@.ROWCOUNT returns the rowcount of

what I need to do is determin is if a single driver is assigned to multiple
cartons within an order. for Instance say driver #1 was assigned to Carton
100 and driver #24 was assigned to Carton 101 and carton 102. All 3 of these
cartons are in Order #1000

returns an error in my vb.net application because the select wants to return

what I need to do is determin is if a single driver is assigned to multiple
cartons within an order. for Instance say driver #1 was assigned to Carton
100 and driver #24 was assigned to Carton 101 and carton 102. All 3 of these
cartons are in Order #1000
Order# Carton# Driver#
1000 100 1
1000 101 24
1000 102 24
What I need to get to is this without the select (becuase doing it this way
returns an error in my vb.net application because the select wants to return
rows)
select c_driver from Cartons where orderid = @.orderid
if @.@.RowCount = 1
--Only one driver exists for this order
Update orders set oDriver = (select distinct c_driver from cartons
where orderid = @.orderid)
if @.@.RowCount > 1
-- Multiple Driver exists for this Order

why this won't work for you:
if (select COUNT(*) from cartons where orderid = @.orderid) = 1
BEGIN
Update orders set oDriver = (select distinct c_driver from cartons
where orderid = @.orderid)
END
ELSE
BEGIN
-- do something else...

... Given that, however, I should ask why you're updating your orders table
with the driver from the cartons table? Why denormalize your data like
that?

only update when all cartons in the orders have the same driver#.
I left out the DISTINCT in my example it should be:
select DISTINCT c_driver from Cartons where orderid = @.orderid
If all drivers are the same for the cartons in the Order I should have 1
row, if there a seperate drivers I should have more than 1 row
The way the db is set up is to have one row for an order in the Orders
Table, ? Rows in Cartons table joined together on Orders.orderid =Cartons.Orderid based on the #of cartons shipped with the order. All of the
pricing and driver commissions are based on the total $'s charged from the
Orders table. So I need to update the orders table with the correct driver
information, but only if the driver is the same. Little round about I know.

Rather than storing the data in two places (which has data integrity
implications), have you considered creating a view that will return the data
in the way you need it for reporting?

Help with "enableEventValidation"

The "enableEventValidation" feauture is new for .Net 2.0

When I had a page that called back to itself through the use of a pushbutton, I recieved an error stating:

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@. Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I went into my web.config file and inserted the following as suggested by microsoft:

<system.web>
<pages enableEventValidation="true" />
</system.web>

Now the error has gone away, however, the whole point of this particular page is to allow me to edit a row in a datagrid. When I click on the edit button, the page is called back to itself but I the chosen row (and none of the page for that matter) is availible to be edited.

Any ideas on what I am doing wrong? I want to call back the page so that I can edit the row that I chose by clicking on that row's "edit" button.

Help using a value from one dataset to lookup a value from a second dataset

Hi All,

I'm quite new to SSRS (and .net development as well) so any help would be useful. My problem is this: I'm running a report from a Sybase ASE datasource to pull data into a table control. One of the fields I'm pulling in is called assignment group. Now, in the same report output I also need to display who the manager of that group is... unfortunately this information is not stored in the same database. We store the manager information in a completely seperate Oracle database. So, I need some method of 'linking' the data from my Sybase dataset to a table in Oracle and I can't quite figure out how to go about it. Every record would have a manager and there could be 10k records returned so I need to be carefull about performance issues.

I was starting to go down the path of creating a .net dataset in a custom assembly which would be filled via a query to the Oracle database. What I was thinking is to create and fill a dataset with my lookup data from Oracle then, in the report, call a function from the table control which would search through the dataset in memory and return the actual manager name.

Am I on the right track or am I overcomplicating the solution? Will this be too inefficient from a performance perspective? Would a subreport be a more efficient solution?

There are a couple of solutions for you:

1) you can write a custom data extension that does the magic merge under the covers. A custom assembly won't help here because it operates on one row at a time - if you have a reasonable nuumber of rows, it might work, but with lots of rows it will probably be inefficient.

2) you can use the Linked server feature of SQL Server. This allows you to build a table/view that uses ODBC connections to other data bases to retrieve data. It has pretty reasonable performance and you don't have to create and maintain custom code. Downside, is you need to add a SQL database in addition to your existing Oracle and Sybase ones :-).

Hope that helps,

-Lukasz

HELP to write stored procedure whose values are calculated automatically in database

Hi frdz,

I m creating my web-application in asp.net with C# 2005 and using sql server 2005.

I have created the stored procedure for the insert,update.

I want to know how to write the mathematical calculations in the stored procedure..

Pls tell me from the below stored procedure were i m making the mistake ??

As the discount and the total amount are not calculated by itself...and stored in the database

How to convert the

@.discpercentnumeric(5,2) to

@.discpercent ="NoDiscount" should be displayed when no discount is being given to the customers...

ALTER PROCEDURE CalculationStoredProcedure @.accountidint output, @.accountnamevarchar(20), @.opbalnumeric(10, 2), @.opbalcodechar(2), @.totalnumeric(10, 2), @.clbalnumeric(10, 2), @.clbalcodechar(2), @.discpercentnumeric(5,2), @.discamtnumeric(10, 2)asbeginset nocount on if @.opbalISNULL OR @.opbal = 0beginselect @.opbal=0select @.opbalcode=' 'select @.clbal= 0select @.total= 0select @.clbalcode=' ' @.discpercent ="NoDiscount" @.discamt=0end select @.accountid =isnull(max(accountid),0) + 1from accountmasterselect @.total=@.opbal - @.clbalfrom accountmasterselect @.discamt=@.total* @.discpercent/100from accountmasterbegin insert into accountmaster(accountname,opbal,opbalcode,clbal,clbalcode )values ( @.accountname,@.opbal,@.opbalcode,@.clbal,@.clbalcode )end set nocount offend

Thanxs in adv...

Hello my friend,

It appears you are using 1 field for 2 purposes; numeric calculation and text display. I would avoid doing this.

Declare another parameter (e.g. @.DiscDisplay) to hold a copy of the @.discpercent variable when a discount is being applied, and have it set to 'NoDiscount' if @.discpercent is 0. Then just display @.DiscDisplay on the web page in both situations.

Kind regards

Scotty

thanxs for the reply...

can u pls help to calculate this for my above stored procedure its not working..

select @.total=@.opbal - @.clbalfrom accountmaster
select @.discamt=@.total* @.discpercent/100from accountmaster

|||

Looks like there is some confusion here. You are calculating a percentage from values in parameters. Then why do you have a "..FROM AccountMaster" in your SELECT?

select @.discamt=(@.opbal - @.clbal )* @.discpercent/100

should do.

|||

select @.total=(@.opbal - @.clbal )
not working in database it shows me NULL only

I tried with this also but don't work pls help me...

if (@.total IS NULL or @.total = 0)
begin
select @.total=(@.opbal - @.clbal )
end

thanxs for ur replies....

|||

Could it be because either @.opbal or @.clbal is null?

I would use the following: -

IF (ISNULL(@.Total, 0) = 0)
BEGIN
SET @.total = (ISNULL(@.opbal, 0) - ISNULL(@.clbal, 0))
END

SELECT @.Total

Kind regards

Scotty

Hello again Sheenaa,

You say that you have put it all together based on our help. Can you show us all of the procedure that you have put together and we can see if you have made any mistakes.

Kind regards

Help talking to stored proc

Can someone please lend a hand.
I am a total noob at this .NET/ASP stuff. I simply need help passing and returning values to a stored procedure.
Here’s my sp.

ALTER PROCEDURE [dbo].[returnIdUser]-- Add the parameters for the stored procedure here @.sessionUservarchar(25)OUTPUTASBEGIN-- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements.SET NOCOUNT ON;-- Insert statements for procedure hereSELECT idUserFROM tblUsersWHERE domainUser = @.sessionUserEND

So when the user logs into to the default page (windows authentication) I capture their domain\login in a session variable (sessionUser). On the next page, when the page loads I need to pass this to my stored proc and get the idUser in return.
Here is what I have for the page load so far.

try{ SqlConnection cxnReturnID =new SqlConnection(ConfigurationManager.ConnectionStrings["cxnLeaveRecords"].ConnectionString); SqlCommand cmdReturnID =new SqlCommand("returnIdUser", cxnReturnID); cmdReturnID.CommandType = CommandType.StoredProcedure; cmdReturnID.Parameters.Add("@.sessionUser", SqlDbType.VarChar, 25).Direction = ParameterDirection.Output; cmdReturnID.Connection.Open(); cmdReturnID.ExecuteReader(); cmdReturnID.Connection.Close(); cmdReturnID.Connection.Dispose(); Session["sessionUserID"] = cmdReturnID.Parameters["idUser"].Value;}catch (Exception ex){ lblStatus.Text = ex.Message;}

Of course this fails cause I don’t know what I’m doing. My error label shows the following: "An SqlParameter with ParameterName 'idUser' is not contained by this SqlParameterCollection."

Can someone point me to what I’m doing wrong?

Hmm.. You mixed up every thing here..

First you need to a pass an input parameter and expect an out put paremeter. So, your stored procedure should have two paramets defined in it.. You have only one

And also, in your c# code, you need to assign the value of session variable to the input parameter, which you have not.

Anyway, try this..

ALTER PROCEDURE [dbo].[returnIdUser]
-- Add the parameters for the stored procedure here


 @.sessionUservarchar(25),

 @.idOUT varchar(25) outAS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
 -- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
set idOUT = (SELECT idUserFROM tblUsersWHERE domainUser = @.sessionUser)

return @.idOUTEND

and your code to

cmdReturnID.Parameters.Add("@.sessionUser", SqlDbType.VarChar, 25).Direction = ParameterDirection.Input;

command.Parameters["@.sessionUser"].Value =  Session["UserName"]

 cmdReturnID.Parameters.Add("@.idOUT", SqlDbType.VarChar, 25).Direction = ParameterDirection.Output;

SqlDataReader reader = cmdReturnID.ExecuteReader();

 reader.close();

 Session["sessionUserID"] = cmdReturnID.Parameters["idOUT"].Value;

Even though, the code looks real, its not... I typed by hand, so beware of small errors...

Hi , in your example I guess you want to pass a session user into the stored procedure and return idUser. In this case your stored procedure should be :

ALTER PROCEDURE [dbo].[returnIdUser]-- Add the parameters for the stored procedure here (@.sessionUservarchar(25))ASBEGIN-- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements.SET NOCOUNT ON;-- Insert statements for procedure hereSELECT idUserFROM tblUsersWHERE domainUser = @.sessionUserEND

And here is the modified code:

try { SqlConnection cxnReturnID =new SqlConnection(ConfigurationManager.ConnectionStrings["cxnLeaveRecords"].ConnectionString); SqlCommand cmdReturnID =new SqlCommand("returnIdUser", cxnReturnID); cmdReturnID.CommandType = CommandType.StoredProcedure; cmdReturnID.Parameters.Add("@.sessionUser", SqlDbType.VarChar, 25); cmdReturnID.Connection.Open(); SqlDataReader sqldr = cmdReturnID.ExecuteReader(); cmdReturnID.Connection.Close(); cmdReturnID.Connection.Dispose(); Session["sessionUserID"] = sqldr.GetString(0); }catch (Exception ex) { lblStatus.Text = ex.Message; }

Here I use sessionUser as an input value and read idUser with SqlDataReader.Hope this helps.|||it took some alterations, but finally got it to work. Thanks to both of you!

Help switching to SQL Authentication

At the moment my asp.net app is working ok and I can connect to the database using windows authentication, however i'm trying to use sql authentication on my local computer.

i'm using sql server studio at the moment to manage the database. And tried numerious combinations of things to try and get it working and allow me to connect to the database using SQL authentication but still no luck :(

can anyone give me some rough step by step instructions to setting up the sql username and password for forms authentication and activating it for a certain database?

thanksWhen you say forms authentication, I assume you mean that in your web.config file you have something like this:

<authentication mode="Forms">
<forms loginUrl="Default.aspx" protection="Validation" timeout="300"/>
</authentication
If so, then a connection string that works connecting to sqlserver is this:

<add name="PolarIntegrationConnectionString2" connectionString="Data Source=INSP8600;Initial Catalog=PolarIntegration;Integrated Security=True"
providerName="System.Data.SqlClient" /
Let me know if that doesn't help.
