Hi all,
I asked a similar question a few weeks ago but I didn't explain myself to well so I was hoping for some more input.
I have created a webpage in Visual web developer that contains a gridview that points to an SQL table.
All works well as far as searching the table and sorting.
The SQL table itself is Droped ( deleted ) and then re-created every 1 minute from a query to a linked DB2 database so that we have a "live" table of our DB2 system but in SQL.....
However,
There is now a requirement to be able to ADD data to this SQL table. eg: a comments field.. from the website.
My procedure for re-creating the SQL DB is now useless as any data added through the website would be lost when the table gets re-created.
What is the best way for me to achieve a permanent table in SQL that gets updated from the Linked server DB2 but that I can also add comments from the front end (Website Gridview)..
I'm assuming some sort of update query and a join to a seperate, permanent table that contains the comments?.
Please help.
hiii, i am using asp.net 2005 and sql server 2005...i hav a page in which i have used gridview and sql data source..i have written the update command for the same..the problem is when i add the where clause in the query i get an error ,,,,here is the code
UpdateCommand="UPDATE SMEtre_Master SET FirstName =@FirstName, LastName =@LastName, Type_of_SME =@Type_of_SME, Agency_Name =@Agency_Name, Email =@Email, Address =@Address, Phone =@Phone, Mobile =@Mobile, Fax =@Fax, Experience =@Experience, City =@City, State =@State where SME_Id=@SME_Id"
I put a grid view on a web form ,when I run it -the SELECT, EDIT works the UPDATE,DELETE makes an error although I use the sama data,I added the error : Anyone can help?

Hi,I use view to join difference table together for some function. However,when the "real" table fields changed (e.g. add/delete/change field). Theview table still use the "old fields".Therefore everytimes when I change the real table, I also needed open theview table and save it by SQL enterprise manager manually for update theview table field.Can we use a SQL command or other method to update it directly?Regards,Silas
hi, i have done some testing and its only when i put a grid view or any other type of data viewer on the page, and then connect it to the sql datasource that i get an error Line 1: Incorrect syntax near ')'. now i really cant figure out what it is, here is the code i am using SQL data source code : asp:SqlDataSource ID="SQLDS_view_one_wish" runat="server" ConnectionString="<%$ ConnectionStrings:wishbank_DBCS %>" SelectCommand="SELECT [msg], [Date_Time] FROM [tbl_MSG] WHERE (([Activated] = @Activated) AND ([msgID = @msgID]) )ORDER BY [Date_Time] DESC"> <SelectParameters> <asp:Parameter DefaultValue="Y" Name="Activated" Type="String" /> <asp:SessionParameter Name="msgID" SessionField="sWV" Type="String" /> </SelectParameters> </asp:SqlDataSource>
session variable code which sends it to this page protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) { GridViewRow row = GridView1.SelectedRow; Session["sWV"] = row.Cells[1].Text; Response.Redirect("www/viewwf.aspx"); }
if you have an idea please let me know as im stuck!
Inside my gridview, the user can key in new record, delete record and update record. but dont know why my insert function cant work out and i dunno why this is happen? Can somebody help me out with this?Thanks My Code:<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"InsertCommand="INSERT INTO [rest_info] ([resname], [menu], [price], [date]) VALUES (@resname, @menu, @date, @price)"<InsertParameters> <asp:Parameter Name="resname" Type="Char" /> <asp:Parameter Name="menu" Type="char" /> <asp:Parameter Name="price" Type="Decimal" /> <asp:Parameter Name="date" Type="datetime" /> </InsertParameters></asp:SqlDataSource>
i seem to have problems with my grid view not displaying anything when if i test my SQLDataSource, it shows me rows of data.i seem to have this problem only with my Stored procedure, or when i change my Database structure, like add fieldsHere is my procedure: can i do this? select a row and also return a varchar?ALTER PROCEDURE dbo.SelectUpload ( @FileName varchar(50), @Return varchar(MAX) = NULL OUTPUT ) AS SELECT * FROM Uploads WHERE FileName = @FileName
RETURN SELECT WebPath FROM Uploads WHERE FileName = @FileName
Perhaps I was seeing things earlier, and it's really a minor thing, but when I display query results in Management Studio, isn't there a setting that turns the background of cells containing NULL to a pale yellow color? I could've sworn it used to do this, and I've searched high and low for a preference setting, but no joy.
I have gridview bound with SqlDataSource control. One of the grid columns is a dropdown list which is populated programatically, (the gridview has template column with edittemplate field with dropdown list), dropdown Value contains of course collection of IDs.Please tell me how to declare UpdateCommand which will update the row with the dropdown list. The problem is with parameter regarding the column with dropdown list. When i declare this parameter and bind it to SelectedValue property of the dropdownlist from edittemplate tag - it doesnt work, because datasource control cannot see this dropdown list. So, how am i supposed to declare the ID of the row being updated in <updateParameters>? Thanks in advance!
Hi there. I looked through many other posts describing scope_identity but I am trying to achieve the same thing from the code behind. i.e. I need to some how call a method to execute the insert command and then return the ID so I can update other tables with this value. I was going down the road of something like: addnew as sqldatasource = new sqldatasource addnew.insertcommand = "Insert into....; def @NewID as scope_identity" addnew.insert()
The problem is I don't know how to add a output parameter using VB or how to retrieve it. Any help would be much appreciated, this is doing my head in.... Doug.
I have consistent column names that load into a grid view. I now need to change the names in the grid view programatically. I was originally trying to get cute with SQL to do this, but I've been told my below solution will not work and I'm better off to do this in the presentation layer. If this is true, remember I'm still wet behind the ears here...how do I do this in vs2005? Here's my post to the SQL devs to give you an idea what I'm trying to do. I have a query that grabs fields from a denormalized table. The result is column names Week1, Week2, Week3....Week26. Users want to see the actual date instead of Week#. So I have a table (lkpdatecaptions ) that contains the fields "fldfieldno" and "Fldcaption". fldfieldno Fldcaption----------- --------------11 9/07/200712 9/14/200713 9/21/2007So fieldno 11 represent week1 and so on. So my hope is to update the alias with a query like: Select fldcaption from forecast.tlkpdatecaptionswhere fldfieldno = 11That quey returns the value of 9/7/2007 and is the value I need to represent the coumn alias name.My current query looks like this:SELECT SUM(forecast.tblforecastdenormalized.fldwk01) AS WEEK1,So can I do something like the following?SELECT SUM(forecast.tblforecastdenormalized.fldwk01) AS (Select forecast.tlkpdatecaptions.fldcaption from forecast.tlkpdatecaptions where fldfieldno = 11), ...
I am looking for a way to create a stored procedure that will show inventory availability. I would like to show the Inventory Name, The Date, and if the inventory is "checked out" using the ID name of the person who has the item.
For example it would look like this:
-------------------------------------------------------------------------------------------------- Inventory Name | 10/24/2015 | 10/25/2015 | 10/26/2015 | 10/27/2015 | 10/28/2015 -------------------------------------------------------------------------------------------------- Laptop | Tom | Tom | Tom | Avail | Avail Projector | Avail | Avail | Avail | Avail | Bob Air Card | Bob | Bob | Bob | Bob | Bob
It seems like I want to do a pivot table but there really is no aggregate so I am not sure what to use.
hi,i have an sql database on my server on the world wide web.i can make a connection to the database in visual web developer and all the tables etc are shown in the 'database explorer' of visual web developerwhen i make the query in visual web developer it does retrieve the data froom the remote server database when i 'test query'.... so looking great!the connection string in the webconfig file is left as the default when i run the prgram on my LOCAL HOST with the inbult server that comes with visual web developer it runs fine......so.....running on my local pc it will connect to the database on my www host server and does display the data from that database.i need to change the webconfig files path to the connection by default it is |DataDirectory|if i change this to the path i suspect is correct as this is the connection i use to the database C:Inetpubvhostsarcvillage.comhttpdocsApp_DataTestdatabase.mdfwhen i change the path in webconfig then it stops working on my localhost and the error when i ftp it to my host is:Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed. any ideas?

I have the membership stuff up and running. I've added a field to the membership table called custnmbr. Once a user logs in, I want store his custnbmr in the session and use that to lookup data in another db. ie: Joe logs in and his custnumbr is 001, he goes to the login success page and sees his list of service calls which is: select top 10 * from svc00200 where custnmbr = 001 (the membership.custnmbr for the logged in user) I know how to do this in old ASP using session variables....but I have no idea where to even start with .Net. Many thanks

Hi ! I have a textbox and a Search button. When the user inputs a value and press the button, i want a datagrid to be filled. The following code runs: Dim connect As New Data.SqlClient.SqlConnection( _ "Server=SrvnameSQLEXPRESS;Integrated Security=True; UID= ;password= ; database=dtbsname") connect.Open() Dim cmd As New SqlCommand Dim valor As New SqlParameter("@valor", SqlDbType.VarChar, 50) cmd.CommandText = "Ver_Contactos_Reducido" cmd.CommandType = CommandType.StoredProcedure cmd.Connection = connect cmd.Parameters.Add(valor) cmd.Parameters("@valor").Value = texto Dim adapter As New SqlDataAdapter(cmd) Dim ds As New System.Data.DataSet() adapter.Fill(ds) GridViewContactos.DataSource = ds GridViewContactos.DataBind() connect.Close() I drag a datagrid on the page and only changed its Id. Into the SQL database the stored procedure is the following: ALTER PROCEDURE [dbo].[Ver_Contactos_Reducido] (@Valor VARCHAR(100)) AS BEGIN SET NOCOUNT ON; SELECT NombreRazonSocial, Nombre, Apellido,TelefonoLaboral, Interno, TelefonoCelular, Email1, Organizacion FROM CONTACTOS WHERE NombreRazonSocial = @Valor OR Nombre = @Valor OR Apellido = @Valor OR TelefonoLaboral = @Valor OR Interno = @Valor OR TelefonoCelular =@Valor OR Email1 = @Valor OR Organizacion= @Valor END When i run the page i can't see the datagrid, and after i enter a text and press the button, nothing happens. What am i doing wrong?? Thks!!
Pardon me if this question is too elementary. I am trying to create a trigger that will cause certain datafields to be updated with values from other data fields in the same row when a certain column, created specifically to fire the trigger, is updated. The purpose of this is to reduce data entry by field personnel.I think I have the create trigger statement correct, but I'm a little confused on the update statement.
In a nutshell, how can I write something like: UPDATE "TABLENAME" SET DATAFIELD1 = DATAFIELD2 WHERE RECORDNUMBER = (THE SAME RECORD NUMBER)
I do know that I have to ensure that sp_dboption Recursive Triggers value is set to false, thanks.
UPDATE #TempTableESR SET CTRLBudEng = (SELECT SUM(Salaries) from ProjectBudget WHERE Project = @Project)UPDATE #TempTableESR SET CTRLBudTravel = (SELECT SUM(Travels) from ProjectBudget WHERE Project = @Project)UPDATE #TempTableESR SET CTRLBudMaterials = (SELECT SUM(Materials) from ProjectBudget WHERE Project = @Project)UPDATE #TempTableESR SET CTRLBudOther = (SELECT SUM(Others) from ProjectBudget WHERE Project = @Project)UPDATE #TempTableESR SET CTRLBudContingency = (SELECT SUM(Contingency) from ProjectBudget WHERE Project = @Project)above is the UPDATE command i am using in one of my stored procedures. I have to SELECT from my ProjectBudget table 5 times to update my #TempTableESR table. is there an UPDATE command i can use which would let me update multiple fields in a table using one SELECT command?
Hello,I'm wondering if there is a way to concatenate two fields or a field and astring value in a single field in a view?Where in Access I might write;[field1] & " (m3)" as TotalVolumeis there a way to do this in an SQL Server View?Thanks!
In my database I have a table for Users, with an int primary key, and a table for Connections, with a combined primary key consisting of two UserID foreign keys. (the smallest first)
At the point I am stuck I have one UserID, lets call it current_user, and a column returned by a select statement consisting of UserIDs. Some of these IDs will likely be smaller than current_user, and some will likely be larger.
What i need to do is construct a view of two columns, combining each of the UserIDs in the column I have with current_user, with the smallest UserID of each pair residing in the first column, and the largest in the second column.
The point of this is to then SELECT the connections identified by the UserID pairs.
I suspect I could accomplish this if I could set individual fields in the a view, but I seem to have missed (or forgotten) that lecture. Anybody want to clue me in?
I'm using a view where I do a few things, including merge two short text fields into one. Just wanted to know if there was an alternative way of doing this:
Example: SELECT first_name + ' ' + last_name AS full_name FROM names
It works - but it seems rather blah. Is there something that'd be more "proper"?
Hello:I have an Access 2K form I built from a SQL Server 7.0 view. I want tolock certain fields in the database from users so they can see them onthe views and forms, but NOT be able to edit them.I've looked in BOL, MS SQL Server web page and SQL Server 7.0 books andcould not find how to do this.Any advise will be greatly appreciated.Thanks,Richard
Is there a limit on the number of fields that can be displayed in a table object in a data source view in SSAS 05? One of the tables (the fact table) in my data source view is displaying only 50 fields. The table actually has many more than that. One of the fields that is not displaying is a foreign key that I need to link to a new dimension table. I have tried refreshing the view, but it doesn't bring in any additional fields.
I've a DateTime field in a table and I want to separate it into two fields in an SQL Server 2005 view one for Date and the other for Time so What is the function I can use to do this process?
I am using BI Dev Studio for SS2005 in a research (as opposed to a production) environment. Often I want to compare the results of multiple models using the same attributes. If I switch to a different model, the Design view completely resets. Is there any way to retain the same field names with different models in the Design view?
My current workaround is to give my models similar names with AR, DT, CL, LOG, NN suffixes and make global changes in the DMX.
