How To Retrieve Data As XML From SQL Database

Feb 28, 2007

Hi,

I have a website which is designed to search for employee information. I have the search system working which does exactly what I want to, but as an added feature I want there to be a button which, when someone clicks on it, it takes whatever the previous search was and generates a set of data in XML format which is based on the results. For example:

User searches for all entries with Forename = John; Results are listed in a gridview as per expected.

User then presses button with XML on it, and page pops up with just the XML output on it, i.e. whatever results are on the gridview but in a nested XML format

<records>
    <record>
       <Forename>John</Forename>
       <Surname>Smith</Surname>
       <Email>j.smith@blah.com</Email>
       <Ext>1234</Ext>
       <DeptList>History</DeptList>
    </record>
</records>

I have created a stored procedure which will take the parameters from the search boxes and return the above information, but I don't know if this is the best way. Here it is for those interested:

CREATE PROCEDURE ps_record_SELECT_NameSurnameEmailExtDeptasXML

@Forename varchar(50),

@Surname varchar(50),

@Email varchar(50),

@Ext varchar(4),

@DeptList varchar(50)

AS

SELECT Forename, Surname, Email, Ext, DeptList

FROM dbo.record

WHERE Forename LIKE COALESCE(@Forename,Forename) AND

Surname LIKE COALESCE(@Surname,Surname) AND

Email LIKE COALESCE(@Email,Email) AND

Ext LIKE COALESCE(@Ext,Ext) AND

DeptList LIKE COALESCE(@DeptList,DeptList)

FOR XML AUTO, ELEMENTS

If someone could be kind enough to help me out with this, I'd be really grateful.

Many thanks,

Tom

Retrieve Data From Database And Display It In A Label

Jan 21, 2008

Below is code for inserting data into the database that I know works, so I thought if I replace  "Insert" with "Select" I could retrieve a specific row from my database and present it in a label or text box but nothing happened. How can I retrieve a row or rows from a database using vb code and display it in a textbox? I'm using visual web developer 2008 which is similar to 2005.
Thank you.
 
 Dim UserDatasource As New SqlDataSourceUserDatasource.ConnectionString = ConfigurationManager.ConnectionStrings("ASPNETDBConnectionString1").ToString()
 
UserDatasource.InsertCommandType = SqlDataSourceCommandType.Text
UserDatasource.InsertCommand = "insert into table1 (Username, comments, points,totalpoints, ipaddress, datatimestamp) values (@Username, @comments, @points,@totalpoints, @ipaddress, @datatimestamp)"
 
 UserDatasource.InsertParameters.Add("username", Context.User.Identity.Name)
UserDatasource.InsertParameters.Add("comments", txtSearch.Text)UserDatasource.InsertParameters.Add("points", points)
UserDatasource.InsertParameters.Add("ipaddress", Request.UserHostAddress)UserDatasource.InsertParameters.Add("datatimestamp", DateTime.Now())
 Dim rowaffected As Integer = 0
 
Try
rowaffected = UserDatasource.Insert()MsgBox("Thanks for the post", MsgBoxStyle.OkOnly, "Post Executed")
txtSearch.Text = ""Catch ex As Exception

Asp.net Page Is Unable To Retrieve The Right Data Calling The Store Procedure From The Dataset/data Adapter

Apr 11, 2007

I'm trying to figure this out
 I have a store procedure that return the userId if a user exists in my table, return 0 otherwise
------------------------------------------------------------------------
 Create Procedure spUpdatePasswordByUserId
@userName varchar(20),
@password varchar(20)
AS
Begin
Declare @userId int
Select @userId = (Select userId from userInfo Where userName = @userName and password = @password)
if (@userId > 0)
return @userId
else
return 0
------------------------------------------------------------------
I create a function called UpdatePasswordByUserId in my dataset with the above stored procedure that returns a scalar value. When I preview the data from the table adapter in my dataset, it spits out the right value.
But when I call this UpdatepasswordByUserId from an asp.net page, it returns null/blank/0
 passport.UserInfoTableAdapters oUserInfo = new UserInfoTableAdapters();
Response.Write("userId: " + oUserInfo.UpdatePasswordByUserId(txtUserName.text, txtPassword.text) );
 Do you guys have any idea why?

Retrieve Text File Data In SSE For Data Acquisition System

Oct 24, 2007

Hey All,
I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel. I am trying to use SSE to retrieve the data from the text file, and parse each line of data into individual columns in a databse. Then I want to be able to extract the data associated with a particular ATD channel number from the databse and display it in the appropriate text field on a windows form.
I've got the MCU programmed. I have no problem collecting the data from the serial port, and I can do the visual basic programming okay. I have absolutely no clue how to read the data into the database, continuosly read new values into the databse, and then access the stored data to update the text fields on the form. Please help if you can, I've been working on this specific problem for a couple of weeks and I'm not making any progress. Thanks.

Retrieve Data

Mar 18, 2008

Hello,

Before I ask a question, I am visually impaired and cannot read printed words only on a screen. I am 51 years old and have been coding professionally since I was 23 (yes that long). I have four apps on the market and run a small consultancy company in the UK and my SQL knowledge is scant. I have read two books on the subject and thought I had an idea on how SQL works.

I used to belong to another forum but they gave me a hard time so please go easy on me.

I developed an ADO app ages ago and remembered some of it ...

I have four tables (the following is a simplified version of the real thing)

MainTable (Contact data like name address etc. 23 fields)
Towns (Two fields TownUIN and TownName)
Counties (Two fields CountyUIN and CountyName)
Countries (Two fields CountryUIN and CountryName)

My database is normalised to 3NF and contains no duplicate or redundant data.

My problem ...

Sample data

Main:
MainUIN MainName MainTown
1000 Fred Bloggs 1
1001 Fred Smith 2

Towns:
TownUIN TownName
1 Bradford
2 Leeds

SELECT MainName,MainTown FROM Main WHERE MainUIN=1000 returns
'Fred Bloggs' 1 (the TownUIN)

I want ...
'Fred Bloggs' 'Bradford'

It was suggested I use
SELECT MainName,MainTown FROM Main,Towns WHERE MainUIN=1000 AND TownUIN=MainTown
This returned 'Fred Bloggs' 'Bradford' but was slow.

My question is what am I doing wrong?

I am using SQL Server 2005 Express with VB.Net 2005 on Vista Business and XP.

I am sorry my SQL knowledge is weak please dont get angry just tell me the basic thing that I do not know.

In header of myphp I have the meta: <meta HTTP-EQUIV="content-type"CONTENT="text/html; charset=UTF-8">.I have the following problem:- I trie to do a query using ODBC (version 3.525.1022.0) and SQLServer odbc driver (version 200.85.1022.00). The query doesn'tretrieve information in utf format and accents and extra charactersaren't showed correctly.- I trie to di the query usin native OLE DB. I use mssql funtions andthe problem is the same.If I install php4 and I use "newCOM("ADODB.Connection",NULL,CP_UTF8);", then it works correctly.Anybody knows if its posible to retrieve data from sql-server in utf-8format using php3?I see in other postings that odbc driver only accept utf-8 in version3.7 or higher? Is it true? If is true, where I can download odbcdriver 3.7?Thank's in advance.Miki.

Retrieve Database Image By 2 Ids

Feb 28, 2008

Hi, I'm stuck trying to figure out how to call an image from the database by certain ids.  I want to get it like this: page.aspx?pictureid=#&userid=#
here's the show.aspx:Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim PictureID As Integer = Convert.ToInt32(Request.QueryString("ppID"))Dim MemberID As Integer = Convert.ToInt32(Request.QueryString("mID"))
'Connect to the database and bring back the image contents & MIME type for the specified pictureUsing myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("objConn").ConnectionString)
Const SQL As String = "SELECT [ppMIMEType], [ppImageData] FROM [tblPP] WHERE ([ppID] = @ppID) & ("[mID] = @mID)"Dim myCommand As New SqlCommand(SQL, myConnection)
myCommand.Parameters.AddWithValue("@ppID", PictureID)
myCommand.Parameters.AddWithValue("@mID", MemberID)
myConnection.Open()Dim myReader As SqlDataReader = myCommand.ExecuteReader
If myReader.Read ThenResponse.ContentType = myReader("ppMIMEType").ToString()
Response.BinaryWrite(myReader("ppImageData"))
End If
myReader.Close()
myConnection.Close()
End Using
End Sub
 here's the formview to display image with datasource:
<asp:FormView ID="PictureUI" runat="server" DataKeyNames="ppID,mID" DataSourceID="PicturesDataSource" AllowPaging="False" EmptyDataText="There are currently no pictures uploaded" HorizontalAlign="Center" CellPadding="0">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("ppID", "~/Show.aspx?ppID=" & 1 &"mID=" & 1 &"") %>' />
 
</ItemTemplate>
 
</asp:FormView>
 
<asp:SqlDataSource ID="PicturesDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:Connect %>"
SelectCommand="SELECT [ppID], [ppDateTime], [mID] FROM [tblPP] ORDER BY [ppDateTime]">

How Do I Retrieve The Available Tables In A Database

Sep 20, 2004

I need to retrieve the available tables in a database in SQL Server 2000. I found this command and although it works I can't figure out how to filter the results.

exec sp_tables

I don't want to return the whole list, just the tables starting with "OV" and "SV". Does SQL Server 2000 support a wildcard? Like can I have it search for "OV*" or do I have to use LIKE. Did google search with no helpful results. I remember in mySQL this was simply "SHOW Tables" but this command isn't supported in SQL Server 2000.

any help would be appreciated

thanks

Right Way To Retrieve Data From Sql-server

Mar 19, 2007

Last night I face performace problems in web site. I got like 100 000 users and site fails because of sql-connections.
Currently I'm making a new connection for every query, and my code looks like this:Public Shared Function executeQueryReturnDataset(ByVal strsql As String) As DataSet
Dim sqlConnection As New SqlConnection(Connstr)
Dim sqlCommand As New SqlCommand(strsql, sqlConnection)
Dim sqlDataSet As New DataSet

Try
sqlConnection.Open()
Dim myDataAdapter As New SqlDataAdapter
myDataAdapter.SelectCommand = sqlCommand
myDataAdapter.Fill(sqlDataSet)
Catch e As Exception
Console.Write(e.ToString())
Finally
sqlConnection.Close()
End Try
Return sqlDataSet
End Function I was wondering would it be better to save an instance from connection object to memory and use that same connection for all querys?

Retrieve Data From SQLDataSource

Jan 23, 2008

Background:I am using Visual Studio 2005 Standard SP1 to create an ASP.NET website that accesses an SQL 2005 database.  I am using vb.net as well.I am passing an ID in a query string from one page to the next, where I retrieve it using an SQLDataSource.  The data will only be one row; it is returning customer information.Problem:I need to be able to get specific fields from the SQLDataSource and populate some textboxes.  Honestly, I'm not really sure where to begin.  For the sake of argument, let's say that I am working with this:'My TextboxDim LastName As Textbox'My SQLDataSource (filtered by query string using the customer's ID to only get 1 customer's information at a time)SQLDataQuestion:So, how would I go about retrieving the lastname field from SQLData and inserting it into the textbox LastName?Thanks,    J'Tok

How Do I Retrieve Sql Data In A Distinct-like Way?

Jul 23, 2007

I wonder how to get top 1 row per account number. Let's say I have

--snip--
IDENTITY_ID | ACCT_NUMBER
0001 | 1111-2222
1001 | 1111-2222
2002 | 2222-0000
3003 | 2222-0000
4004 | 1111-2222
--snip--

I used the SQL-Query here


Code:


SELECT * FROM BACKUP_LOG ORDER BY IDENTITY_ID DESC
[code]

Since they are in descending order by IDENTITY_ID, so I only want to get 1 distinct account number somehow.. Like this...

[code]
4004 | 1111-2222
3003 | 2222-0000



I couldn't figure it out.

Thanks...
