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.
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
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.
Hi, I have been trying to get the scope Identity after inserting a record using an ObjectDataSource. I can't find what event, or how to get the value that the scope identity returns. Here is my Sproc.
ALTER PROCEDURE dbo.[YourCompany_LanCustomer_Insert] ( @DNNUserID int, @FirstName nvarchar(50), @LastName nvarchar(50), @Address nvarchar(50), @Address2 nvarchar(50), @City nvarchar(50), @State nvarchar(50), @Zip nvarchar(50), @EmailAddress nvarchar(50), @PhoneNumber nvarchar(50), @CustomerID int OUTPUT ) AS INSERT INTO YourCompany_LanCustomer (DNNUserID, FirstName, LastName, Address, Address2, City, State, Zip, EmailAddress, PhoneNumber, DateEntered) VALUES (@DNNUserID, @FirstName, @LastName, @Address, @Address2, @City, @State, @Zip, @EmailAddress, @PhoneNumber, getdate()) SET @CustomerID = Scope_Identity() RETURN
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)

Is an index in a database the equivalent for a <TH scope="col"> in a columnof atable in the html code?--Luigi ( un italiano che vive in Svezia)https://www.scaiecat-spa-gigi.com/s...kor-italien.php
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?
This is kind of what I'm trying to do in my MS SQL 2000 query. ShouldI be able to reference s1.col1 inside the 2nd derived table?I'm getting 'Invalid column name col1' and it's coming from the 2ndderived table (I've commented out other refs to just it to check).Maybe I need to use a temp table instead.SELECT s1.col1,(SELECT * FROM(SELECT COUNT(zzz) AS SomeTotalFROM tab1WHERE s1.col1 = zzz)) AS RowCount) /* error here */FROM(SELECT col1 FROM table) AS s1Thank you!
We're working on a new release of a software.In the existing version, each client connects and executes a long batch ofanalysis on some tables.In the new release, we need to allow each client to execute analysis on asubset of data, according to certain login information.Our idea is:1) Connection to db2) Creation of one View according to restrictions3) Execution of analysis using just created view and some tables.The problem is that executingcreate view myvista asselect * from tb_data where testo='A1'from two different clients, creates just one view.Question: Does it exist a way of creating a VIEW with a connection scope,something like 'select into ##temptable'?We tried Create View #MyVista or ##Myvista, but this name is not accepted.Alternative way, is creating a ##TempTable, at the beginning of the batch,and using it as data source instead of full table, but, due to really hugeamount of data, this could really disturb server performances.Thanks for any helpAlberto
I have a detailed report ..with summary lines and detailed lines (drill down).
I have a column with a function "RowNumber(Nothing)" which is supposed to just count the rows
when I put this in the summary row for the column I need in the Design Layout section and run the report, I get numbers on the summary lines which include the number of rows in the level below (detailed rows).
I just want to number the summary rows sequentially without taking into consideration, the number of detailed rows.
How do I modify RowNumber(Nothing) to exclude counting the detailed rows....???
I have 2 packages and they get executed in SQL Job.
Each of these package will have seperate transactions with the Database and I am not sure of how to maintain the transactions between these 2 packages.
Can someone explain me the necessary setting to achieve this. If I set the TransactionOption property to Required (or) Supported in both these packages, will the Transaction Scope of the first package extend to the second one.
For me, If the second package ends up in error, the first package should also have to be rollbacked.
Source table : Result (contains 100 rows with primary key Reuslt_ID)
Destination Table : stage_RESULT (same structure as source table)
Source table gets regular inserts with new result_ids. I want my package to pick up new result_ids only, i.e. (Result_ids > maximum(result_id) in stage_RESULT.
My package is designed to do the following :
1) Retrieve current maximum result_id into @max_result_id from RESULT_STAGE
2) Retrieve rows from Result where result_id > @max_result_id
sounds simple, BUT.. it's not working.... my source table resides in a SQL Server 6.5 database so I am having to use a datareader source adapter to pull the data.
The first time I run the package (when my stage_RESULT) is empty, the package pulls all 100 rows from the source to the destination table, but the second time I run it, it still retrieves all 100 rows again even though the value of the variable is greater than all result_ids in the source.
What am I doing wrong?
I have a variable defined at the package level. I use a SQL Query Task to assign a value to this variable (this bit works just fine). I then use this variable in my data flow task in order to retrieve data using the My expression used for my datareader source adapter is :
"select * from result where result_id > " + (dt_str, 10, 1252) @[max_result_id]
I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
Hi, i'm trying to run wrap a transaction around a block of code to make sure every statement is carried out. Here's what i have: using (TransactionScope ts = new TransactionScope()) { ... ts.Complete();}The code executed in the ... part is a set of sql commands within my dal. If this above expression takes less than 30 seconds everything is carried out correctly, however if it takes longer than 30 seconds i receive an sql timeout error. I tried modify the above code to: using (TransactionScope ts = new TransactionScope(TransactionScopeOption.Required, TimeSpan.FromMinutes(5))) { ... ts.Complete();} But it did not seem to make a difference. I suppose the easiest option would be to increase the timeout for every sql command in my dal but i feel that the 30 second timeout is sufficient for a single command. Appreciate if someone could tell me how this should be done correctly. Thanks
My office gave me assignment to find out the scope & limitations of the two Microsoft database applications - MS Access and MS SQL Server. After the findings, we have to chose the more appropriate database for our new project, which will have a humble start but may grow big in a year or two.
I will apreciate the info in facts & figures (not only in general).
