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
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:
i have 2 dropdownlist which is ddlCategory and ddlItem.i want<<< a)both ddl get data from sql db.b)view the data in gridview. i need code in vb.net to retrieve and post.tq
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.

let's say I have a table named "myTable" in a SQL database:
UniqueID FirstName FamilyName
1 Elizabeth Moore
2 Chris Lee
2 Robert McDonald's
I want to create a SQL query should contain a parameter for example: SELECT * FROM myTable WHERE UniqueID = @TextBox OR FirstName = @TextBox OR FamilyName = @TextBox,
and when I type in my TextBox the ' * ' character, it should retrieve the whole table...
hope anybody understood, will be happy to explain more.
we have some reference tables in in a specific database. that other applications need to have access to them. Is it possible to create a view in the application's database to retrive data from ref database while users just have access to the application Database not the view's underlying tables?
I am using C# in Visual Studio 2008 and remote database as sql server 2008 R2. I want to read remote database table's field value and i have to move that read value to string variable. how to do it.

SQL Query:
Select top 1 item_picture_mst.picture from item_picture_mst where item_picture_mst.item in (select item_all.item from item_all where item_all.item = 'GL-10000') ORDER BY item_picture_mst.picture DESC;
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.

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.

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.

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?
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
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?
