DataSource Controls ::character To Column Name Then A New String Random Will Auto Insert Into Column Random?
Dec 15, 2010
I create a table as picture below :
when I insert any character to column Name then A new string random will auto insert into column Random (picture below) I had used Trigger but It was error !
I want to column Random use to code :
DECLARE @myid uniqueidentifier
SET @myid = NEWID()
insert into table_1 values(@myid, substring(CONVERT(varchar(255), @myid), 1, 5))
but It must auto like column Number (column Number is Identity)
I have a table with three fileds userID, userName, userPassword.I have 100 rows in that table, now I want to update the userPassword column with new random generated string password.
My issue is that , need to change the column name(following format "Remove first character and after 3rd character insert colon") of the gridview (which is binded with XMLTextReader). Without changing directly XML file, Required to change the column name dynamically at runtime .
I need to split the words from random character displayed.For example character like
Textbox1--Textbox2, the mention character have to be split up only by the ('--') and both the characterslike("Textbox1","Textbox2") have to be display in corresponding textboxs.
I have a gridview which has a column of auto generated select buttons, where a user can select a row.However, I would like to add a column header to my auto generated select buttons in order to make the gridview look complete, but I am unable to see how I can do this. Does anyone know how I can add a header text to an auto generated select button?
Dim RandomNumber As New Random() Dim num As Integer num = RandomNumber.Next(1, 75).ToString Try Dim Cnn As New OleDb.OleDbConnection("File Name=E:WebRHIUDLShelf_Life.UDL;") Dim da As New OleDb.OleDbDataAdapter("SELECT tbMaster_List.dbMFG, tbMaster_List.dbDescription, tbInStock.ID, tbInStock.dbMFG_Lot_Code, tbInStock.dbDateReceived, tbInStock.dbDateOpened, tbInStock.dbExpireDate, tbInStock.dbLocation FROM (tbInStock INNER JOIN tbMaster_List ON tbInStock.LnkToMaster = tbMaster_List.ID) ", Cnn) Cnn.Open() Dim dtt As New DataTable() da.Fill(dtt)
This is were I am stuck.
I need to filter all rows out except where row(index) = num
Me.GridView4.DataSource = dtt Me.GridView4.DataBind() Catch Label1.Text = "Error: Unable to Pull Data" End Try
How can I select a random row and then update or delete it? I've found how to get a random row, using SELECT TOP 1 column FROM table ORDER BY NEWID() do I have to make another select using this result in order to update the row, or it can be done more efficiently?
Is there a way I can automatically update a 'Date' column in my database table to the current date whenever any cell in that record is updated?I've started looking into table triggers a little bit and I'm wondering whether I can do it using this?
I've build a random string generator but I'm having a problem whereby if I call the function multiple times say in a Page_Load method, the function returns the same string twice.here's the code
Public Class CustomStrings ''' <summary>' ''' Generates a Random String' ''' </summary>' ''' <param name="n">number of characters the method should generate</param>' ''' <param name="UseSpecial">should the method include special characters? IE: # ,$, !, etc.</param>' ''' <param name="SpecialOnly">should the method include only the special characters and excludes alpha numeric</param>' ''' <returns>a random string n characters long</returns>'
Public Function GenerateRandom(ByVal n As Integer, Optional ByVal UseSpecial As Boolean = True, Optional ByVal SpecialOnly As Boolean = False) As String.............
Is there any method by which we can retrieve random data from a dataset or rather directly from a table.
For example, I have around 30 questions in my table, I just wanted to display 20 among them and that too in a random order without the same item repeating. Can we achieve this using SP or through some Dataset manipulation?
I have a database call that is comparing UserID column of two tables. The UserID is a uniqueidentifier. The page errors on the r.read() line with Conversion failed when converting from a character string to uniqueidentifier. I'm not sure how to code this to avoid the error.
cmd.CommandText = "SELECT a.CenterName FROM Centers a INNER JOIN UserInfo u ON a.CenterID = u.CenterID WHERE u.UserID='{ + SessionManager.UserID + }'"; r = cmd.ExecuteReader(); r.Read();
I work on an ASP.Net 4 project that uses forms authentication.The majority of our users login without any trouble, however, something strange is happening with a small number of users and I think we've narrowed it done to the User Agent string.Most users when logged in will see a fairly standard looking URL, e.g. http://mywebsite.co.uk/Web/Pages/Default.aspx, the "web" folder is the root of the site.
Some users when logged in are producing URLs such as
http://mywebsite.co.uk/Web/(F(wjNTtmLFYK3PyAUD09idKtZcyRPlf3Mlc6_rJMMwd1r0EvxeL1ROKYoTbd6KQWJNJHebiCs8qN4laZAItib4ZmcfMy75KhGlBrMCjY-47phUNQiJ_Q0-E3ntvf8tscjxfD5A0lVXau-UxDvN6gTgW1TkwhA1))/Pages/Default.aspx. I can only assume the garbage characters are some sort of session identifier string.
These obscure, long URLs work fine for some pages, but a lot of pages (including our home page) use the LoadControl(path) method to dynamic load content, or have hyperlinks to static files on the server (e.g. PDFs). In these scenarios the users with the long URLs crash the application as obviously the files it's looking for don't exist because the paths have been obscured with garbage characters.
We can reproduce this error by using masking the User Agent in Firefox to emulate the Googlebot, and sometimes the iPhone. Is there a particular reason why some user agents will produce this behaviour? Can anyone shed any light at all on why the random string is being injected into every URL on our sites?
I have an orders table with a column names orderID. What I want to do is insert a new record and get the value from the new orderID column. The orderID is my Primary key. The Insert SQL I have now is -
INSERT INTO orders (creditAutorizarionNumber, OrderName, OrderPersonPhone, OrderPersonEmail) VALUES (@creditAutorizarionNumber,@OrderName,@OrderPersonPhone,@OrderPersonEmail)
How do I write the query to get the newly entered orderID ?
how do i multiply the columns like this. for now static explanation would be ok but eventually i would like to make it dynamic so there would be a text box for users to enter the amout they like e.g 160g then the table would know to multiply the columns by 1.6.
I am trying to create a stored procedure where I can insert null values in columns that have a foreign key constraint and allow nulls. The columns I am trying to insert nulls into are commentid and imageid. I have created an Insert statement in a stored procedure and I get the foreign key constraint error. Can you tell me how to allow inserting data in the other columns without having to insert anything in the commendid and the imageid?
Here is my exec of the stored procedure that is not working:
Region ( ID int, Name varchar(50), Description varchar(51) )
One thing I can use is to retrieve the max(ID) from region and store it in a variable and increment the variable sequentially and insert. But, if any other user inserts a record while I am executing this script then max(id) might clash with the id inserted with other user causing my script to fail.
Is there any other option to insert record sequentially base on the highest number in the table.
I'm currectly tryin to access a specific value in my database in a specific column. I'm tryin to use the primary key of the table to access the actual value in the row of that ID.
The current code:
[Code]....
Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?
