ADO.NET :: Doing An Update To A Table In Sql Server?
Sep 28, 2010
I have a form that is being populated with data from a sql table. The user can update via textboxes information on the form and click update. The data should then be updated back to the table.
For some reason, When I add the parameters I need for the query, it is not grabbing the update from my textbox, it is showing the value that was populated upon load. I tried to change the customer's phone number. When I run my code it is pulling in the original phone number and not picking up my change.
I'm using the ASP.Net Membership provider, but I don't want to allow system administrators to DELETE any users. Instead, I simply want to mark them as locked out (aspnet_Membership.IsLockedOut) of the system so they can't log in when an administrator assigns them to a role titled "Inactive". Make sense? Right now my trigger isn't throwing any errors, but it's not working either. Here's my trigger (which is on the aspnet_UsersInRoles table):
UPDATE SPECT SET SRE = CLSS.NEWSID FROM SPECT INNER JOIN student (NOLOCK) ON student.ID = SPECT.ID INNER JOIN CLSS ON CLSS.GID = SPECT.GID ON CLSS.GID = student.GID WHERE student.PID = '20201' AND CLSS.PID = '20201' AND SRE IS NOT NULL
However, student.PID and ClSS.PID need dynamically reach through from table CLSS to get each row of PID.
I have table a and would like update table a whose values from table b, but not update all rows at table a. Only update record ID in table a match record ID in tableC.
Here is my query
update a set a.Desc = b.Desc, a.Value = b.Value from TableA a, TableB b where a.name = b.name and a.ID = b.ID and a.ID in ( select ID from TableC)
I only have 12 a.ID match TableC, but above query update whole TableA.
How to only update 12 record at TableA from TableB?
i want to update table using web service file, i am retriving value like this :
[WebMethod] public DataSet getinfo() { SqlConnection con = new SqlConnection(@"Data Source=WEBTECHNO1WEBTECHNO;Initial Catalog=blogsite;Integrated Security=True");[code].....
how can i update table using this web service , what should return type in update and all these things...
Im trying to design a simple ASP Page where I can reset the IsLockedout to false. The page already identifiesand lists in an editable gridview which displays accounts which are locked out, using the following code:
SELECT [UserId], [IsApproved], [IsLockedOut], [LastLoginDate], [FailedPasswordAttemptCount], [UserName] FROM [vw_aspnet_MembershipUsers] WHERE ([IsLockedOut] = @IsLockedOut)
However when I run the edit and update it updates all the records and not just the one I am trying to edit. The code for the Update is: UPDATE aspnet_Membership SET IsLockedOut = 0I have tried various Where Clauses to restrict it to only the one account I am editing but I get lots of different syntax errors.
I have a table that is not getting updated. My insert command is working fine. Here is the update code from business logic area and stored prodecure. The SP works fine when I execute it from sql mgmt studio and updates the table:
I have the following code-behind that executes when a user clicks a verification link from their email. The code works up to the sql update part - the user role is updated, then I get the error below. Can someone look at this and tell me what is going wrong:
Code-Behind:
[Code]....
Error:
No mapping exists from object type System.Web.Security.MembershipUser to a known managed provider native type.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentException: No mapping exists from object type System.Web.Security.MembershipUser to a known managed provider native type.
I have created normalised data tables to hold look up information (such as venues, players, teams etc) and want to dynamically update the 'matches' data table (my transactions) using webpages instead of running SQL queries.
What I want to do is select a name from a drop down list and then post the relevant ID associated with that name to my 'matches' table. At the moment I can only link to the value in the drop down list, i.e. the name which is incompatible with the validation which expects a primary key integer.
I'm sure this problem is a fairly common one but I haven't found the right answer on any of the tutorials or blogs, all of them assume that the data is de-normalised or describe things in more technical ways than I can yet understand. If anyone can point me to a 'how to article' or tell me what I am doing wrong, I would be grateful.
I am looking for simple asp.net code example showing a simple webform task.
When user clicks a button, a stored procedure fires which runs an update-table query (not pulling any parameters from the user) and returns a count of the number of rows that were updated when the query was run.
Within my stored procedure I have the parameter @RowCount=@@ROWCOUNT.
All sample data I have found online has been C# or VB, but nothing that I can apply to my asp.net program.
Again, this is a simple task that for whatever reason I cannot find examples of online.
Two machines. One a little faster than the other. The slow one runs windows xp, visual webdeveloper express 2010, sql server 2008. The fast one runs windows server 2008, visual wev developer express 2010, sql server 2008.The code in queston involves an automatically generated update function in one of the table adapters, called 'adapter'. Our C# code generates a data table called 'table', with which we update our 'datatable' in the table adapter.
The table has about 100 entries.We then update our datatable in the .xsd file by calling.
int rowsaffected = adapater.Update(table);//this is the line that takes long on fast computer return rowsaffected > 0;//since function returns a bool On the slow machine this line of code takes a few milliseconds.One the fast machine it takes 5 seconds.These results are consistent. It has nothing to do with one machine being busy, the other idle.
What could be the reason and how could it be solved? How can the same code, on the same platform, on a faster machine take 500 times longer than on a slower machine?
Using VisualWebDeveloper 2010 on the development machine. All nice and fast.Using VisualWebDeveloper 2008 on the server. Server runs on Windows Server 2008 and has IIS 7.
It looks like that when 'table', a datatabe filled up in C# code behind, is getting longer, then the server (whether running the website on IIS or on the local host of VIsualWebDeveloper2008) is really slowing down. Checked it in debug mode and traced it down to
Adapter.Update(table);
Are there any know issues? Could it be that there is incompatibility between different version of SQL server or something like that? The update works, it is just awefully slow, but only on the server.
CDC or Change data capture is a new feature in SQL Server 2008, which is an ability to record changes to table data into another table without writing triggers or some other mechanism, Change data capture records the changes like insert, update, and delete to a table in SQL server.I have sql 2005 and I have created triggers and tables CDC to capture the data. everything functions good and the data is being updated in the _CDC tables. all i need to do now is to generate the updated data as a report (excel/html)- what should I do ......?i need to show only the updated columns when user selects the date periods ( Range between dates ) and the person name - i need to display any updated info about that person during that period. So this updated columns about this person should be displayed in excel formatted column wise.
I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
[code]....
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?
I'm sure this has been answered many times already, but I still can't seem to find exactly how to search for this issue, so apologies in advance.
Anyway, I have a VB script for entering a row of data into a table by a web user. When this row of data is entered, I wish to take some of the values from the columns of the "primary" table, and have that data automatically create a new row of data in a "secondary" table. I think I'm part of the way there, here is my script:
[code]...
"ProductsByMfr" is the "primary" table - the table that the user adds data into when the button click event is fired.
"DealerPricing" is a "secondary" table that I wish to have some of the data from the newly-entered row in ProductsByMfr copied into. Am I even close here?
I am trying to delete or add rows in a table but since the table is in an update panel,upon deletion the row goes away and then comes back.I have tried using return false but it does not seem to work in IE or FF.
I'm trying to update one my my tables from a field in another table.
I have Address fields on both tables and the old table has some addresses I need to copy over (I dont want to copy/paste or type them all in obviously). I basically need to:
my main intention is that, the exsisting table of sql server database(.dbo) with 1000's of records, that should be import to a new access database table(.mdb).for example if we want to had a new table in db2, of exsisting table in db1 with some conditions by using "select * into New_Tabel from (select * from Exsisting_Table where <Condition>) as objectName". Here the new table is created and records inserted in one execution in db2. The same work should be done for access(sqlserver db --> Access db).Here the new access database table with given name (as string_sysdate) must be created dynamically by clicking a button (multiples time creating new table).Is there any query or c# code for sql server database to access database.
