I have been using tis page as a reference http://forums.asp.net/thread/1511323.aspxbut i cant seem to get this to work. The above page suggests using Dim newId As Object = e.Command.Parameters("@RETURN_VALUE").Value to get the value but when i do that i get an error that Command is not a member of system.web.ui.webcontrols.formViewInsertedEventArgs Can anyone help?ThanksMatt
Hi folks I'm using a function to create a record on a database, and then I want to return the ID of that record to passinto another function. I believe its scope identity that does this, but I'm not sure how to do it. public static void putrecordin(string record) { SqlCommand cmd = new SqlCommand("insert Table (record) values (@record; scope identity)" conn.Open(); cmd.Parameters.Add(new SqlParameter("@record", record)); cmd.ExecuteNonQuery(); conn.Close(); another(new-record-ID, anothervalue); } public static void another(string new-record-ID) {do stuff } so you'll see I have a function called putrecordin, and at the end of the sql statment I want to return the id of the new record and pass it into another function called another. Anyone know how to do this? Thanks!
To Parse it out. This then has to be inserted into another table with an identity column (damn Identity column), and I need to grab the generated id for each row, because then there are other children tables that need to be populated.
Question: Is there any set way to grab multiple generated id's? Or do I need to loop or use a cursor?
Hi, I've been trying to insert data in a Sql server (.mdf) db and use SCOPE IDENTITY to be able to insert an id in both the parent and the child tables. However, I don't know how to write one of the lines correctly: Dim MyConn As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("myConnectionString").ConnectionString) Dim MySQL As String = "INSERT INTO Document (fid, serie, vnr, datum, vtext, sign) " & _ "Values (@fid, @serie, @vnr, @datum, @vtext, @sign) Select @verid=SCOPE_IDENTITY()" Dim Cmd As New SqlCommand(MySQL, MyConn) With Cmd.Parameters .Add(New SqlParameter("@fid", fid)) .Add(New SqlParameter("@serie", SerieDropDownList.SelectedValue)) .Add(New SqlParameter("@vnr", vnr)) .Add(New SqlParameter("@datum", datumet)) .Add(New SqlParameter("@vtext", VtextTextBox.Text)) .Add(New SqlParameter("@sign", sign)) .Add(New SqlParameter("@verid", SqlDbType.Int)) 'HERE IS THE LINE THAT SHOULD BE CHANGED (OR SO I THINK) End With MyConn.Open() Cmd.ExecuteNonQuery() Dim p As SqlParameter = Cmd.Parameters.Add("@verid", SqlDbType.Int) p.Direction = ParameterDirection.Output Dim verid = Cmd.Parameters("@verid").Value.ToString For Each row As GridViewRow In StampelGridView.Rows Dim kpnr As String = row.Cells(0).Text Dim kst As String = row.Cells(1).Text If kst = " " Then kst = "" Dim projekt As String = row.Cells(2).Text If projekt = " " Then projekt = "" Dim debettext As String = "0.00" Dim kredittext As String = "0.00" If row.Cells(3).Text.Length > 3 Then debettext = Replace(row.Cells(3).Text, ",", ".") If row.Cells(4).Text.Length > 3 Then kredittext = Replace(row.Cells(4).Text, ",", ".") Dim ptext As String = row.Cells(5).Text If ptext = " " Then ptext = "" Dim MySQLpost As String = "INSERT INTO Vpost (verid, kpnr, kst, projekt, debet, kredit, ptext) " & _ "Values (@verid, @kpnr, @kst, @projekt, @debet, @kredit, @ptext)" Dim Cmdpost As New SqlCommand(MySQLpost, MyConn) With Cmdpost.Parameters .Add(New SqlParameter("@verid", p)) 'THIS SHOULD CHECK OUT AS WELL... .Add(New SqlParameter("@kpnr", kpnr)) .Add(New SqlParameter("@kst", kst)) .Add(New SqlParameter("@projekt", projekt)) .Add(New SqlParameter("@debet", debettext)) .Add(New SqlParameter("@kredit", kredittext)) .Add(New SqlParameter("@ptext", ptext)) End With Cmdpost.ExecuteNonQuery() Next MyConn.Close() In other words, the verid is the id of the new post in the first table. This id should be inserted in the new table as well. Thank you very much in advance fro helping me out! I've worked a LONG time with this. Pettrer
Is it possible to write the InsertCommand for a SqlDataSource to return the value of the AUTONumber of a field generated when a new record is added to a database table and display that value on label1.Text after the postback of ItemInsersted event? For example, <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NearMissConnectionString >" InsertCommand="INSERT INTO [NearMiss] ([Branch], [Division] VALUES (@Branch, @Division); SELECT SCOPE_IDENTITY()" SelectCommand="SELECT [NearMissID], [Branch], [Division], FROM [NearMiss]" <InsertParameters> <asp parameter Name="Branch" Type="Int32" /> <asp parameter Name="Division" Type="String" /> </InsertParameters> </asp:SqlDataSource>
NearMissID would be the value of the autonumber generated by the SQL Server
I am trying to retrieve the value of the autonumber generated when a new record is inserted into a SQL 2000 Database using a SqlDataSource attached to a FormView. Is this possible? Can some give me a short example of how to retrieve that value and display it in a textbox? Thanks for any help with this. It seems like it would be a common issue for .net developers.
Ok, So I am trying to do 1 insert into a table and then insert more information into another table but I need to get the [TKTNUM] (the column with the idenity increment on it) value that was auto-generated when the insert was done. I have done a search and I am well aware that this are tons of posts on this subject already that is how I found out to use the SCOPE IDENTITY(). But nobody is using the insert syntax that I am using and since I am new, I don't understand any of it. I think they are using ADO.NET. I am extremely new to ASP.NET so take it easy on me ok guys... But can someone take a look at my code and tell me what the problem is. Again, I'm new so I am learning as I go so I might be missing something really stupid. Any help would be greatly appreciated. O yeah, I am running this code in a button click event NOT in a stored procedure (dont really know now to use those anyway).Here is my code:Protected Sub submitBtn_Click(ByVal sender As Object, ByVal e As System.EventArgs)Dim newTktNumIf Page.IsValid ThenDim it3Conn As SqlDataSource = New SqlDataSource()it3Conn.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString1").ToStringit3Conn.InsertCommand = "INSERT INTO [IT_TICKET] ([REQUEST_DATE], [LOGGED_BY], [REQUESTED_BY], [TKTSTATUS],[NEEDED_DATE]) VALUES (@REQUEST_DATE, @LOGGED_BY, @REQUESTED_BY, @TKTSTATUS,@NEEDED_DATE); SELECT @newTktNum = SCOPE_IDENTITY()"it3Conn.InsertParameters.Add("REQUEST_DATE", DateTime.Now.ToString)it3Conn.InsertParameters.Add("LOGGED_BY", User.Identity.Name)it3Conn.InsertParameters.Add("REQUESTED_BY", User.Identity.Name)it3Conn.InsertParameters.Add("TKTSTATUS", "NEW")it3Conn.InsertParameters.Add("NEEDED_DATE", needByTB.Text.ToString)it3Conn.Insert()End IfMsgBox("Ticket Number: " & newTktNum & " has been created", MsgBoxStyle.OkOnly, "Ticket Created")End Sub
I have a table EugeneTest(id_num, fname, minit, lname)where field "id_num" is type IDENTITY and has UNIQUE constraintLet's say 2 user execute this code at the same time:DECLARE @return integeruse EugeneTestINSERT employees( fname, minit, lname)VALUES( 'Eugene3', 'F', 'Josephs')SET @return = @@IDENTITYIs is not possible to get duplicated value in id_num column becuase ofUNIQUEconstraint, but is it possible the both user get the same @@IDENTITYnumber( for example, if @@IDENTITY is evaluated and kept somewhere in thebuffer before the data actually get written to the disk )Thanks, Eugene
I have taken three dtsx files and re written them into one each in its own container. I use the XML Task task alot which the File connection is set by a variable and the variable value is evaluated by expression (the expression makes up the path/filename from other variable values). All the variables that make up the connection are at the container scope. The package will not run now because it is saying that the source (created by variables) for the file connection do not exist.
It seems the answer is that file connections exist at the package level therefore the variable has to be at the package level. This seems to be alot of variables i now have to move to package level to generate the XML source connection. Which in essence makes it confusing as to which variables operate in which container.
My question is can we easily move variable scope (Not ideal as we have alot of variables at package level) Or Can we do the same for connection managers as we do for variables and have them only used in a scope? (this will be ideal as some connections only need to be at a container scope)
I'm trying to effecinty page through many rows of data with the gridview and objectdatasource. I'm having trouble. I'm using a table adapter with predefined counting and select methods. I have tested all the methods and they all work properly. But when I configure the object datasource to use the table adapter, and set the gridviews datasrouce, the page doesn't load and I wind up getting "time out". Any help? <asp:GridView ID="GridView1" runat="server" AllowPaging="True" DataSourceID="objTopics"> <Columns> <asp:BoundField DataField="topic_title" /> </Columns> <EmptyDataTemplate> <p>NOTHING HERE</p> </EmptyDataTemplate> </asp:GridView> <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" EnablePaging="True" OldValuesParameterFormatString="original_{0}" SelectMethod="GetTopics" SelectCountMethod="GetTopicsRowCount" TypeName="TopicsTableAdapters.discussions_GetTopicsSubSetTableAdapter"> <SelectParameters> <asp:Parameter DefaultValue="1" Name="startRowIndex" Type="Int32" /> <asp:Parameter DefaultValue="10" Name="maximumRows" Type="Int32" /> <asp:Parameter DefaultValue="1" Name="board_id" Type="Int32" /> </SelectParameters> </asp:ObjectDataSource>
I have a problem with efficiently paging with gridview and objectdatasoruce. I have GetPosts1(startRowIndex, maximumRow, topic_id) and GetPostsCount(topic_id). I tested each procedure and each are working correctly. The problem is with the controls. Here is the code for the controls. <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False" DataKeyNames DataSourceID="ObjectDataSource2"> <Columns> <asp:BoundField DataField="RowNumber" HeaderText="RowNumber" SortExpression="RowNumber" /> <asp:BoundField DataField="post_id" HeaderText="post_id" SortExpression="post_id" /> <asp:BoundField DataField="post_subject" HeaderText="post_subject" SortExpression="post_subject" /> <asp:BoundField DataField="post_text" HeaderText="post_text" SortExpression="post_text" /> <asp:BoundField DataField="post_time" HeaderText="post_time" SortExpression="post_time" /> <asp:BoundField DataField="topic_id" HeaderText="topic_id" SortExpression="topic_id" /> <asp:BoundField DataField="UserName" HeaderText="UserName" SortExpression="UserName" /> <asp:BoundField DataField="UserID" HeaderText="UserID" SortExpression="UserID" /> </Columns> </asp:GridView> <asp:ObjectDataSource ID="ObjectDataSource2" runat="server" OldValuesParameterFormatString="original_{0}" EnablePaging="True" SelectMethod="GetPosts1" SelectCountMethod="GetPostsCount" TypeName="PostsTableAdapters.discussions_GetPostsTableAdapter"> <SelectParameters> <asp:QueryStringParameter DefaultValue="48" Name="topic_id" QueryStringField="t" Type="Int32" /> </SelectParameters> </asp:ObjectDataSource> When I run the page, I get "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll" and then "The thread '<No Name>' (0xbe0) has exited with code 0 (0x0)." Could the problem be with null or empty values in the returned data?
I have a gridview control that accesses either an objectdatasource or a sqldatasource both of which excute "select * from customers" the affected-rows property when using the sqldatasource is always the number of rows returned (what I want) but i need to use an object data source to access a table-adapter when using the ODS affectedrows is always -1 no matter how mayn rows were returned why is this is there another way to get the number of records returned by an ODS

The function that is supposed to delete a row, is not working. The function is called, and the windows is refreshed, but the row is not deleted.Can anyone see anything wrong with this code:public static void DeleteBlog(int original_BlogID) { string insertCommand = "DELETE FROM Blog WHERE BlogID = @BlogID"; SqlConnection myConnection = new SqlConnection(Blog.ConnectionString); SqlCommand command = new SqlCommand(insertCommand, myConnection); command.Parameters.Add(new SqlParameter("@BlogID", original_BlogID)); myConnection.Open(); command.ExecuteNonQuery(); myConnection.Close();}
How can you use SQL Full Text Search CONTAINS() with an asp.net 2.0 ObjectDataSource using @Parameters? MSDN says something like this, but only works directly using like the Query from SQL Manager: USE TestingDB;GODECLARE @SearchWord NVARCHAR(30)SET @SearchWord = N'performance'SELECT TestTextFROM TestingTableWHERE CONTAINS(TestText, @SearchWord); I tryed to mak something like that work with the DataSet DataAdapter Query Builder for the ObjectDataSource, but you can't use DECLARE or SET. SELECT TestTextFROM TestingTableWHERE CONTAINS(TestText, @SearchWord); But again it says @SearchWord not a valide SQL Construct Is there anyway to make a DataSet.DataApater.ObjectDataSource work with an SQL FTS CONTAINS() with @Parameters?
I wrote a Scalar UDF in SQL2005 that returns an integer. I want to be able to display this integer in a ASP.Net 2.0 web page. I typically use a DAL for all data so I added an ObjectDataSource as a Qeury that contains only the UDF. How do I easily display the value in a Label Control or? I have tried to use a Repeater with a label, a Formview with a Label, all to no avail. Any suggestions?

I've been trying to figure out the usage of "Nothing" as the scope parameter, and the more I try, the more I can confused.
It says on the RDL spec:
"For expressions inside data regions:
.......
Specifying the keyword Nothing as the scope is equivalent to specifying the outermost data region containing the report item in which the aggregate is used."
It seems that what's it saying is that if I have an expression in a table as = last(somefield, "the name of the table") is the same as = last(somefield,Nothing) But, apparently it;s not. (I tried last, first,sum, count,CountRows, min, max...........) it doesn't matter where I put "=last(somefield,Nothing)" in the table (i tried table header,footer, detail, and table group header, footer), none of them worked. and I tried it everywhere in matrix, in charts. It's just not working. It always complains about the invalid scope not being the containing data region, containing grouping or dataset name.
However, the only way I get the "Nothing" as the scope to work is in a RunningValue function, not in any other aggregate funcitons.
Anyone help me with this, please... I need a complete definition on the usage of Nothing as scope.
Variable scope of package variables should be in a dropdown. I want to copy (20+) variables from one sequence container to another. Do I have to retype all the names, types and initial values because I made the mistake not to place them one level higher?
I am really starting to like CTEs. My only qualm is that you can only use them within the first statement after you declare them. I wish they would remain active for the duration of the sql batch just like everything else (variables,local temp tables, ect). Is there any trick so that you can use them multiple times? Maybe define them as a string and do dynamic sql or something like that? Hopefully (i have not researched the new version of sql server) in SQL Server 2008 the scope has increase. Anyways any help would be appreciated.
While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
