I have a database on a server that im trying to update using asp.net. I tested this on another server and everything worked perfectly. The test system was set up where the website is hosted. But the live system is placed on a different server than the webpage. Does that make a difference? Test System Client -> Website/database Live System: Client -> website -> database I created a user account to use when accessing the database on the live system because i read the double hop causes problems. By using that account i can access and view the data. But whenever i update it nothing happens. NO ERROR either. It works perfectly but does nothing. Anyone have any ideas please?!?!?!
Hi all, just need a LITTLE help here. I am very close, I know I am, but just can't seem to fit the last piece in on this.

I'm using SQL Server Management Studio to do an extremely simple table update (I thought). I wish to fill a newly added table field with a value, however I didn't do this before... What I do is:
Im looking for example code to make a sql update... I want to use command.Parameters and variables from text boxes and i'm unsure how to do this... Please help.

Here I have the following command Dim dtNow As DateTime = DateTime.NowSqlDataSource1.UpdateCommand="Update [db] Set [LW]='TRUE', LWD=dtnow Where [PK]=@PK"What I was ttrying to accomplish was , in my grid view, when someone clicks update, it would automatically set LW to true and set LWD to today's date. No user intervention required. However, I figured the above script would not work. What would I have to do to make LWD = dtnow? I do not want to give the user the option to update anything.
Hello, I'm using a Gridview to display a list of servers. Each server has a column in a table called "Enabled." I want to create a button that is supposed to toggle the value called "Enabled." I am able to make the button either to set Enabled to true or false, but I don't know how to make it toggle. Here is the command:UpdateCommand="UPDATE [ServerStatus] SET [Enabled] = 1 WHERE [ServerName] = @ServerName" The button is a buttonfield in the gridview:<asp:ButtonField ButtonType="Button" CommandName="Update" HeaderText="Toggle" ShowHeader="True" Text="Toggle" /> Does anyone know the syntax, or a way to make the button set Enabled to true when it is false, and false when it is set to true?

I thought this would work. I use this code to update another table in another page. In this page, after someone has cast their vote for an article, the article db is updated for the current rating. It reads all the votes so far and takes and average and is supposed to write this number to the article database. There are 2 columns. ArticleRating is a decimal and is the average and ArticleReaders is the total number of votes. The response.write in lines 3 and 4 are the correct numbers appearing in my upper left corner of the page. They are not getting written to the db.

I wrote a sproc which does four things: 1. It looks at an option master to see if the record exists before inserting a new one 2. If the record is not there it inserts the optino record 3. Once the record is inserted I have to run a CASE statement on the record to determine its level 4. Once the level is determined, the record needs to be updated with the correct level. 1-3 work fine (when run without the update command). However, even though I set a criteria, UPDATE still updates and not the one records. Any idea why? set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO
IF EXISTS (SELECT 1 FROM optionmaster WHERE BuilderID = @BuilderID AND OptionID = @OptionID AND CommunityID = @CommunityID AND PhaseID = @PhaseID AND PlanID = @PlanID AND ElevationID = @ElevationID)
BEGIN SELECT ' This option already exists in your Option Master' END ELSE BEGIN
--if the option record option does not exist, insert it
--once the option record is inserted, case it to find the its level (1-9) --update the record with the approciate level.
UPDATE Optionmaster SET optionlevel (
SELECT CASE WHEN CommunityID = '0' AND PhaseID = '0' AND PlanID = '0' AND ElevationID = '0' THEN '9' WHEN CommunityID = '0' AND PhaseID = '0' AND PlanID > '0' AND ElevationID = '0' THEN '8' WHEN CommunityID = '0' AND PhaseID = '0' AND PlanID > '0' AND ElevationID > '0' THEN '7' WHEN CommunityID > '0' AND PhaseID = '0' AND PlanID = '0' AND ElevationID = '0' THEN '6' WHEN CommunityID > '0' AND PhaseID = '0' AND PlanID > '0' AND ElevationID = '0' THEN '5' WHEN CommunityID > '0' AND PhaseID = '0' AND PlanID > '0' AND ElevationID > '0' THEN '4' WHEN CommunityID > '0' AND PhaseID > '0' AND PlanID = '0' AND ElevationID = '0' THEN '3' WHEN CommunityID > '0' AND PhaseID > '0' AND PlanID > '0' AND ElevationID = '0' THEN '2' WHEN CommunityID > '0' AND PhaseID > '0' AND PlanID > '0' AND ElevationID > '0' THEN '1' END AS OptionLevel --provides the option level required to update the record FROM optionmaster WHERE (BuilderID= @BuilderID And OptionID = @OptionID and CommunityID = @CommunityID AND PhaseID = @PhaseID AND PlanID = @PlanID AND ElevationID = @ElevationID)) --even through I specify the above criteria, it upates all records.

Hello All I m trying to update a table whose col name will be read from another table. For e.g. Table1 gives the result: 'emp1', 1, 'John' 'emp2', 2, 'Mike' Now in the second table, i need to update the table with Col name = 'Emp1' and then from the second row (above), I need to update Col name= 'Emp2' I need to write one Update Statement which will handle all the cases. I tried Update Table2 set @VariableName = ....... but didnt work... How can i do that ?
Hi - I'm using .net2, and have a gridview, populated by a SQL Datasource (Edit, Insert, Delete, Select). Like we all used to do with the datagrid, I've added text boxes into the footer, and a link button, which I'd like to use to fire the Update command. How do I get the link button to trigger the update command? Thanks, Mark
1. I read from a source namely SOURCE. SOURCE is defined like
CREATE TABLE SOURCE
( f1 int, f2 int, f3 int, id int)
, where f1 is unique and id is always null after reading.
2. pass it to a Slow Change Dimension control to separate the new records and changed records
Then for new records,
3. link to a Derived Column control to add in some new columns
4. link to a OLE DB Command control to update field id before write to destination
In Step 4, I use the command :
INSERT INTO global_id_pool
SELECT MAX(id) + 1
FROM global_id_pool
UPDATE SOURCE
SET id =
(SELECT MAX(id) FROM global_id_pool)
WHERE f1 = ?
Using the command, the parameter can't be recognised with an error reported in BIDS. So eventually I had to change the query to the following to make it work
UPDATE SOURCE
SET id =
(SELECT MAX(id) + 1 FROM global_id_pool)
INSERT INTO global_id_pool
SELECT MAX(id) + 1
FROM global_id_pool
I don't mind the parameter can't be added. But after running, I found id field in the table after the OLE DB Command control is still NULL while the field in the SOURCE table in database is updated. So it seems the OLE DB Command worked on database but the data in memory cache wasn't affected.
So I just wonder if there is way to UPDATE the cache in OLE DB Command control. Many thanks for any help.
Please let me know what is wrong with my code below. I keep getting the "Incorrect syntax near 'UpdateInfoByAccountAndFullName'." error when I execute cmd.executenonquery. I highlighted the part that errors out. Thanks a lot. --------------------------------------------------------------------------------------------------------------------------- public bool Update( string newaccount, string newfullname, string rep, string zip, string comment, string oldaccount, string oldfullname ) { SqlConnection cn = new SqlConnection(_connectionstring); SqlCommand cmd = new SqlCommand("UpdateInfoByAccountAndFullName", cn); cmd.Parameters.AddWithValue("@newaccount", newaccount); cmd.Parameters.AddWithValue("@newfullname", newfullname); cmd.Parameters.AddWithValue("@rep", rep); cmd.Parameters.AddWithValue("@zip", zip); cmd.Parameters.AddWithValue("@comments", comment); cmd.Parameters.AddWithValue("@oldaccount", oldaccount); cmd.Parameters.AddWithValue("@oldfullname", oldfullname); using (cn) { cn.Open(); return cmd.ExecuteNonQuery() > 1; } }
I have an update command with 7 parameters, but at run time the order to the parameters gets mixed up. I'm using a stored procedure. At first I have the command type set to text, and was calling it using EXEC spName ?,?,?,?,?,?,? I then named each of the parameters and set their sources. The parameters are like this (samepl name, then source, then type): A : QueryString - intB: Control - intC: Control - intD: None - intE: None - decimalF: Control - datetimeG: Control - datetime At run time I was getting an error that an integer couldn't be converted to date time. So I put a breakpoint in the Updating event and then looked at the parameters prior to update. This is how they looked (Parameter index, paramter name): [0] A[1] B[2] D[3] E[4] F[5] G[6] C It didn't maek any sense. Do, I deleted all of the paramters and readded them. That didnt' work. Then I changed the command to StoredProcedure and refreshed the parameters from the stored proc and it brought them in the right order, but the problem remains the same. I looked at the page source, and there are no indexes in the page source, but the parameters are listed in the proper creation order, as follows:<UpdateParameters><asp:QueryStringParameter Type="Int32" Name="PROJ_ID" QueryStringField="pid"></asp:QueryStringParameter><asp:ControlParameter PropertyName="SelectedValue" Type="Int32" Name="TASK_UID" ControlID="fvTask"></asp:ControlParameter><asp:ControlParameter PropertyName="SelectedValue" Type="Int32" Name="ASSN_UID" ControlID="gvResources"></asp:ControlParameter><asp:Parameter Type="Int32" Name="RES_UID"></asp:Parameter><asp:Parameter Type="Double" Name="Work"></asp:Parameter><asp:ControlParameter PropertyName="Text" Type="DateTime" Name="Start" ControlID="TASK_START_DATETextBox"></asp:ControlParameter><asp:ControlParameter PropertyName="Text" Type="DateTime" Name="Finish" ControlID="TASK_FINISH_DATETextBox"></asp:ControlParameter></UpdateParameters> No mater what I do, at run time ASSN_UID is always the last parameter. I've also run a SQL trace to see how it is actually being executed, and sure enough, its passing the value for ASSN_UID as the last parameter, which obviously doesn't work. Any ideas as to why this would happen or how to fix it? (I guess I can reorder the patameters in the stored proc to match how they are being passed, but still, that wouldn't be a very comfortable solution, since it could perhaps revert at some point or something)
Is there any way I can use a variable from my code behind file in the UpdateCommand of a sqlDataSource? I have tried <%$ strUserGuid %>and<% strUserGuid %> any help appreciated.Thanks Dave
Hi, I tried to use the RETURN_VALUE of a stored procedure in updata / delete commands with a sql-datasource and a stored procedure. The thing works fine with the insert command.But it fails with "too many arguments..." in delete / update. I also tried to handle the updating event like this: protected void sqldsReportSelect_Updating(object sender, SqlDataSourceCommandEventArgs e) { SqlParameter sqP = new SqlParameter("RETURN_VALUE", SqlDbType.Int); sqP.Direction = ParameterDirection.ReturnValue; e.Command.Parameters.Add(sqP);} It brings the same error. Do I make something wrong or is this a bug? Regards Manfred
I have a gridview with a sqlDataSource with the SelectCommand as "SELECT Movie.Title, Movie.Category, Movie.ReleaseDate, ItemForSale.Quantity, ItemForSale.HasUnLimitedQuantity FROM ItemForSale INNER JOIN Movie ON ItemForSale.ID = Movie.ID"
what kinda 'UpdateCommand' do I set so that ItemForSale is also updated from the grid? I tried two update statements seperated with a semicolon but that wouldn't work, any suggestions...
