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 Textbox
Dim LastName As Textbox
'My SQLDataSource (filtered by query string using the customer's ID to only get 1 customer's information at a time)
SQLData
Question:
So, how would I go about retrieving the lastname field from SQLData and inserting it into the textbox LastName?
Okay, I used the SQLDataSource control to get my data from the database table. What or how do I retrieve individual data from the sqldatasource? I want to do some string comparison and manipulation before I display it to the browser. How can this be accomplish?
I'm an "old" programmer but new to ASP.NET. I want to get a value from the SQL Dataset. What I would normally do in other environments is iterate through the dataset to get the value I would be intrested in, but I can't figure out how to do this without using a visual data display object like a Grid view. Typically I want to get a value from the database that I then after manipulating it, like multply by 5, use to format something on the page. thanks in advance, Thommie
I have made a SQLDataSource control with the select command: SELECT COUNT(*) AS 'Antall' FROM Utgivelse WHERE (medieID = @medieID) I want to use the "Antall" result programmatically in C# code. I try the following statement: IDataReader MyReader;
MyReader = CType(SqlDataSource2.Select(DataSourceSelectArguments.Empty),IDataReader); but it doesnot work. Can somebody help me how to get the data from th control ? Tom

Hi I am trying to get the last ID value of a table. The following code worked when a SQLConnection object was used, how do I achieve the same result using an SQLDataSource? this.sqlSelectCmd2 = new System.Data.SqlClient.SqlCommand("SELECT IDENT_CURRENT('Assets')",sqlConnection1); sqlConnection1.Open(); int nID = Convert.ToInt32( this.sqlSelectCmd2.ExecuteScalar() ) ; nID++; dc.FocusedRow["ID"] = nID.ToString(); Cheers Pen
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?

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.

I need to retrieve points column from my database for the specific user that is signed on and sum all of them. How can I do it using the Gridview and also code in vb for a label? Thanks.
Here is my sql procedure: ALTER PROCEDURE dbo.SoftWareShow /* ( @parameter1 int = 5, @parameter2 datatype OUTPUT ) */ @SoftID uniqueidentifierAS SELECT [SoftID], [SoftName], [SoftJoinDate], [SoftSize], [SoftMode], [SoftRoof], [SoftHome], [SoftDemo], [SoftFirstClassID], [SoftSecondClassID], [SoftDesc], [SoftReadCount], [SoftDownCount],ltrim(rtrim([SoftUrlOne])) SoftUrlOne, ltrim(rtrim([SoftUrlTwo])) SoftUrlTwo, ltrim(rtrim([SoftUrlThree])) SoftUrlThree, ltrim(rtrim([SoftUrlFour])) SoftUrlFour FROM [SoftWare] WHERE ([SoftID] = @SoftID) RETURNwhere I retrieve data using sqldatasource, an error appear. how can do ?
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.
Hi.I have a IIS server with php3 installed. I have SQL server databaseand data stored in unicode format (nvarchar fields). 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.

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
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?
Dears, I'm using FormView to insert and retrieve data from SQL Server Database 2000. I'm using stored procedure to insert and display data by using C#. Every time I insert the data, I can't retrive it. To retrieve all the inserted data, I have to close my website, and then reopen it again. I close the connection every time after using the stored procedures, but nothing happened. What do you think the problem is ??
Let us suppose that there are 900 rows in One table, and that table contains neither primary key, nor Identity column. How can I retrieve all the roows from 201 to 250?(like the middle limits) In oracle there is a property called RowID, but is there any such item in SQL server?
I am having a big problem, trying to create datebase. I have 3 tables: SUPERAVATAR, MASTERAVATAR, MEGAAVATAR. - SuperAvatars are heroes in an online role playing gaming. They have an ID, ‘superavatarID’ which contain an UNIQUE NUMBER NOT NULL PRIMARY KEY to identify them. A wisdom – ‘trickster’,’conjuror’,’magician’, etc.. A current owner… who is the user or player of the game and has that Super Avatar– we associate the link to USERID to know the person. SuperAvatars can be fathers or mothers of Mega Avatars. -MegaAvatars are the children of SuperAvatars…. They also have an ID UNIQUE NUMBER NOT NULL PRIMARY KEY to indentify them. A magic power – it can be a ‘Leader’ or ‘Sheep’… A ‘parent’ – parent is the number identifying to know to who Super Avatar belongs. e.g. SUPERAVAT WISD CURRENTOWNER FATHEROF MOTHEROF 1 Thick 3 1 2 Mentally Ch. 11 3 3 Smart 9 2 4 Genius 16 4 5 Thick 19
-We see that MEGAAVATAR 1 has a magic power as Magician and his father is ‘1’. ‘1’ identifies the SUPERAVATAR. We see SUPERAVATARID…. who has the number ‘1’? the first in the row… who has wisdom – thick and he belongs to the USER with ID number 3. -We see MEGAAVATARID… we choose the number 2…. His magic power is as WIZARD… and his father is the number 3. We see SUPERAVATARID now… we look up the SuperavatarID 3…. We can see he has a wisdom – GENIUS… who belongs to the USERID 16 and he is father of MEGAAVATAR number 2. The list can carry on and never stop.
I have this Problems: We create in this example 3 tables: Users, SuperAvatar, MegaAvatar
SQL CREATE TABLE users(userID NUMBER CONSTRAINT pk_user PRIMARY KEY,email VARCHAR2(50) NOT NULL UNIQUE,password VARCHAR2(15) NOT NULL UNIQUE,subscription CHAR(8) NOT NULL CHECK (subscription IN('ACTIVE' , 'INACTIVE' ) ) );
CREATE TABLE superavatar(superavatarID NUMBER CONSTRAINT pk_superavatar PRIMARY KEY, wisdom VARCHAR2(19) NOT NULL CHECK (wisdom IN ('THICK', 'MENTALLY CHALLENGED', 'AWAKE', 'SMART', 'GENIUS')), currentOwner NUMBER NOT NULL, fatherOf NUMBER,motherOf NUMBER);
CREATE TABLE megaavatar (megaavatarID NUMBER CONSTRAINT pk_megaavatar PRIMARY KEY, magicPower VARCHAR2(12) NOT NULL CHECK (magicPower IN('TRICKSTER','CONJUROR','MAGICIAN','WIZARD','SORCERER')), parent NUMBER);
Now, the 3 tables are created….. What happen when we try to insert values to this table? In this case we insert to User Table some examples: INSERT INTO users VALUES('3','john@hotmail.com','great78','ACTIVE'); INSERT INTO users VALUES('9','chrisandsandra@gmail.com','chrisandra)','ACTIVE'); Now, we insert to SuperAvatar some examples; INSERT INTO superavatar VALUES('1','THICK','3','1',''); INSERT INTO superavatar VALUES('3','SMART','9','3',''); | | ‘9’ is the UserID that we already insert to the User table What’s the problem? We have to insert manually the data from USERID to CURRENTOWNER as we didn’t match or link CURRENTOWNER from SUPERAVATAR Table to USERID from USER Table with a SQL CODE. What happen if we have thousands of USERS that they register to this game…? We will never know to how belongs that SUPERAVATAR but if someone do it manually can spend a year.
I am trying to fix this problem …. I add in SUPERAVATAR TABLE ‘CHECK’ in currentOwner..
SQL> CREATE TABLE superavatar (superavatarID NUMBER CONSTRAINT pk_superavatar PRIMARY KEY, wisdom VARCHAR2(19) NOT NULL CHECK (wisdom IN ('THICK', 'MENTALLY CHALLENGED', 'AWAKE', 'SMART', 'GENIUS')), currentOwner NUMBER NOT NULL CHECK (currentOwner IN(SELECT userID FROM users)), fatherOf NUMBER, motherOf NUMBER); * ERROR: ORA-02251: subquery not allowed here
