Using the SqlDataReader, I am retrieveing records from a SQL Server 2005 DB table. Since I am using the SqlDataReader to retrieve the records from the DB, I have to use the Read method of the SqlDataReader like this:Dim sqlReader As SqlDataReaderWhile(sqlReader.Read) Response.Write(sqlReader.GetValue(0) & "<br>") Response.Write(sqlReader.GetValue(1) & "<br>") Response.Write(sqlReader.GetValue(2) & "<br>")End WhileThe records retrieved can only be accessed inside the While loop. I want to access the records outside the While loop as well. Is there anyway by which I can do this, maybe by populating the recordset in an array variable & then using it outside the While loop?
So I have a Web Service that works just fine when I enter the parameter values myself. I get results and can parse it out, storing the results into a table. I even have it working in a "For Each Loop" for one of my variables.  The issue I have is that the Web Service accepts 3 variables, the first being an Array.  How can I populate the array variable for web service?
I have a stored procedure that has a paramter that accepts a string of values. At the user interface, I use a StringBuilder to concatenate the values (2,4,34,35,etc.) I would send these value to the stored procedure. The problem is that the stored procedure doesn't allow it to be query with the parameter because the Fieldname, "Officer_UID" is an integer data type, which can't be query against parameter string type. What would I need to do to convert it to an Integer array? @OfficerIDs as varchar(200) Select Officer_UID From Officers Where Officer_UID in (@OfficerIDs) Thanks
I have two Databases with the same name that reside in different servers. The two servers are linked servers. Each database consists of 5 Tables. The tables have identical names in each database.
The database in ServerA has 5 tables with data, the database in ServerB also has 5 tables with the same schema as ServerA, however the 5 identical tables in ServerB contain no data.
I need to populate the 5 tables in ServerB with the Data from the 5 tables in ServerA.
What SQL code or script can i use to populate the 5 tables in ServerB
Hi i'm pretty new to this, how do i connect to my database a put all the values from one column into the arraylist. Any help and a easy example would be nice Thanks in advance Richard
I am writing a small program (Visual Studio Express 2008) to help me automate populating a database graphically. The program I am writing will keep track of sales figures state by state on a map of the US. This will be accomplished by using a map of the United States overlaid with a hexagonal grid that represents individual sales regions (hexagons). Each hexagon represents a specific sales region, and there can be many sales regions within a state. This small program will populate the database with data specific to each hexagon that is selected by clicking on it with a mouse. A complete set of row entries should be sent to the database every time the mouse is clicked in a hexagon on my map. This program will capture such information as the center x,y pixel coordinates of each hexagon, row & column location of each hexagon, and the state where the hexagon is located. All of this information (HexX, HexY, RowX, RowY, State) has already been figured out or calculated, except that I need help on how to capture, display, and send this information as a new row entry into my database. I need to populate the database hexagon by hexagon, since which state they are in is determined visually. Here is what I need to populate my database with:
Hex_No - each unique hexagon needs to have its own unique number 1,2,3,€¦.n. This should be as easy as assigning a counter that starts at 1 and increments until all hexagons have been processed
Hex_X €“ the pixel x value of the center (x,y) of the specific hexagon, which is known by the program
Hex_Y €“ pixel y value of the center (x,y) of the specific hexagon, which is known by the program
Hex_Col €“ column location of this specific hexagon, which is known by the program
Hex_Row€“ row location of this specific hexagon, which is known by the program
State €“ the current state on the map. This will be selected by me (combobox) prior to clicking on each hexagon within a given state Each of the above is represented by a textbox on a form, except for the State field, which is represented by a combobox. When one clicks on the down arrow of the combobox, one can see that the names of the different states have already been entered and linked to the SQL database. The other textboxes are also linked to a different column in the same database; however they are currently empty due to the fact that this is the very data that needs to be captured by this program. This is what I need for this program to do for every mouse click , once I have moved on to a given hexagon within a given state:
Determine next available Hexagon Number, and assign it to current hexagon, display in textbox, send this as part of row data entry under Hexagon_No column
Capture and display the current hexagon€™s center x, and y (Hex_X, Hex_Y), display this in textbox, send this as part of row data entry under Hex_X, and Hex_Y columns
Capture and display the current hexagon€™s row and column information (Hex_Col, Hex_Row), display this in textbox, send this as part of row data entry under Hex_Col, and Hex_Row columns
Capture and display the current State that is selected manually from the list of database values, send this as part of row data entry under State column Here is an example of what this program might look like in action: http://farm4.static.flickr.com/3172/2285817199_d75f230f8d_o.jpg I am not looking for anyone to write my program, but I would appreciate some ideas on how I can accomplish this. I have figured everything out except the part about displaying the new information on the textbox/combobox form, and sending it to the database as the next row entry. That€™s the part I need help with. Thanks.
Can anyone help with the proper syntax to use to populate a JavaScript array using values from an SQL database. I tried doing the following with no results:
hi i have a database with a table with several columns: ID - primery key customer company now lets say i want to edit one row in the database and i have the primery key ID for that row. so i click on that row (which is displayed in a gridview) when i click I want the text that is in the customer cell to appear in a textbox1 and the same with compeny text I want it to apear in another textbox2. so what code can i write in the GridView1_SelectedIndexChanged eventhandler to populate the textboxes? thank you
Im a newbie with a sql table in a MSDE database that contains fields ofCustName, BrokerName, Type, Status.I am trying to write a trigger that does this:1. When a new record in a table is added, I would like the selectedfields to be copied to another table (call it Master).2. If that Master table already contains a record where the CustName =CustName, then simply ignore. If CustName does not match anything, thenadd the record to the Master TableIn other words, I am trying to create a table (or even a new database)that has unique records in it - making a master customer list.Any hints on how to get started on this?
Hi I'd like to be a little more efficient in my approach when using databases. Although my site is very simple with a low hit rate expected, I would still like to learn the best methods in designing server load conscious code. Basically, I have a page where I'd like to show events broken down into days of the week (Monday - Sunday). All the events contain the same data and only difference being the day. Right now, the only way I know how to make this work is to create a unique sqlDataSource (select * where Day = Monday) then assign it to a ‘Monday’ grid view. I then repeat this same process for each day of the week. As the data is always the same, is there a way to make only call to the database returning all the data, then close the connection and then separate the data there after. To me this seems to be a much more efficient way to manage the data??? Thanks for any help/supportRichard
I€™ve inherited a project from one of the guys on our team who will be out sick for a while. He developed two for marshaling data between System.Drawing.Image and System.Byte(). He€™s storing the byte array data in a database image field.
I€™ve retrieved the byte array data from his database image fields and have successfully converted them to images using his ConvertByteArrayToImage method below. I have also converted and image to a byte array with his ConvertImageToByteArray method below and succfully stored the data in a database image field. However, when I retrieve the byte array data that I stored in the database the last line in his ConvertByteArrayToImage method throws an exception (Parameter is not valid). I€™ve not been able to find a working copy of his code that€™s storing the byte array data. Does anyone see anything I€™m overlooking?
Imports System.Drawing Imports System.IO
Public Sub InsertImage(ByVal pFilename As String)
Try
Dim lImage As Image Dim lBA() As Byte Dim lSQL As String Dim lQuery As Alcon.SQLServer.Database.clsQuery Dim lParameters As New Alcon.SQLServer.Database.clsParameters
lImage = Image.FromFile(pFilename)
ConvertImageToByteArray(lImage, lBA)

I am using SQL server to create a rather complicated client database for a nonprofit organization. I have access to an ancient version of the database in Access format, but would rather create a new database from scratch instead of "up-sizing" the old database. Although the old database is mostly useless, it contains a goldmine of names and addresses that I could use to populate the new database that I'm creating. My question is this: Is there any relatively easy way to cut and paste from external data sources into a new SQL database? For example, I would love to just select twenty rows of "first names" from the old database and then paste that into my new table. Can anyone suggest any quick and easy tricks for populating a new database with place-holder content? Thanks!
I am trying to load in to a new application's database to see if my load procedures will be able to handle the volume and how long I should plan on when I perform our cut over for production. Unfortunately, trying to copy 5.4M rows from one staging table into a production processing table consistently leaves the database in a suspect status, usually stating to perform some type of disk consistency check utility. It happens time after time, is there anything obvious that I could look at to see why this is happening?

I have two CheckBoxList controls. One CheckBoxList is a group of area codes as they apply to our customers, and the second CheckBoxList is a group of categories of those customers. The code below works fine with either CheckBoxList as a standalone (this code applies to the Area Codes selection), but what I need is the VB code to combine the choices a user makes in both CheckBoxLists. Is this where parameterized SQL comes into play? Or can I/should I use an array statement to combine both CheckBoxList choices? Sometimes a user will select nothing in one CBL and a few choices in the other, or vice versa, or a handful of choices in both CBLs, so that they might want only customers in, say two area codes and then only the selected categories of those area codes. Need help on this one, thanks...Protected Sub btn_CustomerSearchCombine_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_CustomerSearchCombine.Click Dim ACSelections As Boolean = False Dim ACItem As ListItem For Each ACItem In cbl_CustomerSearchAREA.Items If ACItem.Selected Then ACSelections = True End If Next If ACSelections = True Then Dim ACSqlString As String ACSqlString = "SELECT Customers.CustomerID, Customers.CustomerName, Customers.CategoryID, Customers.EstHours, Customers.Locality, Categories.Category FROM Customers INNER JOIN Categories ON Customers.CategoryID = Categories.CategoryID WHERE " For Each ACItem In cbl_CustomerSearchAREA.Items If ACItem.Selected Then ACSqlString &= "Customers.AreaCodeID = '" & ACItem.Value & "' OR " End If Next ACSqlString = Left(ACSqlString, Len(ACSqlString) - 4) ACSqlString &= "ORDER By Customers.CustomerName" sql_CustomerSearchGrid.SelectCommand = ACSqlString End IfEnd Sub

My Issue is the next thing: I have a table filled with contracts I have Stoc that checks if contract has expired If I start the Stoc I must give it the contractnumber with it like: SP_expired 8
This works fine but now I want that the Stoc checks all the contracts by just starting the Stoc.
I don't really know how to do this, I have thinking about using an array. But don't have an idea where to start....
