Rowversion Output Parameter
Sep 14, 2007
Is there an equalivent to scope_identity that supports getting the rowversion value last provided by the system?
The reason I'm asking: We're updating a table, and I want to send the rowversion value back to the client as an output paramter so they can update again without running into a false positive concurrency error.
Without something like scope_identity, I have to run a select statement after the update just to get the rowversion that was provided by the system, and that hardly seems efficient.
My goal is to avoid the extra code and the select statement.

After running my ssis pkg for some time with no problems I saw the following error come up, probably during execution of a stored procedure ...
An OLE DB error has occurred. Error code: 0x80040E14. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E14 Description: "The formal parameter "@ReportingId" was not declared as an OUTPUT parameter, but the actual parameter passed in requested output.".
I see some references to this on the web (even this one) but so far they seem like deadends. Doe anybody know what this means? Below is a summary of how the variable is used in the stored proc.
The sp is declared with 21 input params only, none of them is @ReportingId. It declares @ReportingId as a bigint variable and uses it in the beginning of the proc as follows...
Code Snippet
select @ReportingId = max(ReportingId)
from [dbo].[GuidToReportingid]
where Guid = @UniqueIdentifier and
EffectiveEndDate is null
if @ReportingId is null
BEGIN
insert into [dbo].[GuidToReportingId]
select @UniqueIdentifier,getdate(),null,getdate()
set @ReportingId = scope_identity()
END
ELSE
BEGIN
select @rowcount = count(*) from [dbo].[someTable]
where ReportingId = @ReportingId and...lots of other conditions
...later as part of an else it does the following...
Code Snippet
if @rowcount > 0 and @joinsMatch = 1
begin
set @insertFlag = 0
end
else
begin
update [dbo].[GuidToReportingId]
set EffectiveEndDate = getdate()
where ReportingId = @ReportingId
insert into [dbo].[GuidToReportingId]
select @UniqueIdentifier,getdate(),null,getdate()
set @ReportingId = scope_identity()
end
...and before the return it's value is inserted to different tables.

I have a stored procedure which takes an input parm and is supposed to return an output parameter named NewRetVal. I have tested the proc from Query Analyzer and it works fine, however when I run the ASP code and do a quickwatch I see that the parm is being switched to an input parm instead of the output parm I have it defined as...any ideas why this is happening? The update portion works fine, it is the Delete proc that I am having the problems...

In SQL 2005 I use this 'min_active_rowversion()' to return the lowest active rowversion but this function is not available in SQL 2000. Is there any similar kind of thing in SQL 2000. We have 2 different application one on SQL 2005 and other on SQL 2000.
Thanks !

I have a RowVersion/Timestamp column in my table. I check against the RowVersion/Timestamp column when updating rows to check if a row has been updated by another user. I would like to call RAISERROR with a custom message which indicates the current RowVersion/Timestamp of the row in question.
What data type do I convert the RowVersion/Timestamp column into so I can make it part of the custom message which will be a string?
If I convert the RowVersion/Timestamp column into a bigint column, will the max value of RowVersion/Timestamp ever exceed the max value of a bigint? For example, convert(bigint, MyRowVersionColumn)
If the max value of the RowVersion/Timestamp column can exceed the max value for a bigint column, can I convert the RowVersion/Timestamp into a hex string?
Basically RowVersion/Timestamp columns are binary(8) or varbinary(8) so the question could also be answered if it is known if binary(8) can exceed the max value of bigint or if binary(8) can be converted into a hex string
Any help would be appreciated, Thanks!

Hello, I'm attempting to use the Sql Timestamp (Rowversion in 2005) datatype for optimistic concurrency for my SqlDataSource because the table I'm updating has a few columns that can be null which breaks the optimistic concurrency code generated by visual studio. However, the Type's available for SqlDataSource parameters do not include "Timestamp" and everything else I've tried throws exceptions. SO, is there anyway to use the timestamp/rowversion datatype with a SqlDataSource? Many thanks for your help, I have been googling this for literally hours. Thanks again.Drew

Hello all,I am new at SQL Server 2005 and have been reading everything I canfindabout the new optimistic concurrency control mechanisms. As far as Ican tell, the Snapshot Isolation Level is based avoids the use ofshared locks using rowversioning instead.To control rowversions in SQL Server 2000 I was using an extra columnin each table containing a rowversion datatype. What i do with this isfind out if a row was modified. Is it possible in SQL Server 2005 toavoid the use of this extra column, using the new versioning features?What I mean is, if the Snapshot Isolation already manages rowversionsin TempDB, is it possible for me to query those versions using somestored procedures or functions given by SQL Server 2005 system? Whatfunctionalities does SQL Server 2005 gives me for that (anydocumentation pointer would help)?This would allow me to do the exact same processing that i was doingwith the rowversion column in SQL Server 2000 without the need forthat extra column.For all of you my thanks and best wishesSusana Guedes

Hi,
i wanted to read some datasets from a table with the ROWVERSION. Then i wanted to save these records with the ROWVERION- Column in a temp table. Now it seems i cant explicitely write data in a ROWVERSION Column. As i understand its only possible to write a default value in such columns. Only SQL Server itself can write into ROWVERSION columns.
Am i right with this meaning?
Thx in advance...

I have an SQL INSERT statement with an output parameter called @CusRef. I have been trying to store this in a session variable, however all i am able to store is the reference to the parameter object. (The returned value stored in the parameter is an Integer)Session("CustomerReference") = DataConn.InsertParameters.Item("CusRef")I cant seem to find a value field or a method to get the value from a parameter. I have also tried using CType(DataConn.InsertParameters.Item("CusRef"), Integer) but it cant convert the Parameter type to an Integer.Please help,ThanksGareth

A SQL Server 2005 DB table named "Users" has the following columns:
ID - int (IDENTITY)FirstName - varchar(50)LastName - varchar(50)UserID - varchar(20)Password - varchar(20)
Before inserting a new record in the DB table, ASP.NET first checks whether the UserID supplied by the new record already exists or not. If it exists, the new record shouldn't be inserted in the DB table & the user should be shown a message saying UserID already exists. To do this, ASP.NET uses a stored procedure. If the value returned by the stored procedure is 1, it means that the UserID already exists. If the value returned by the stored procedure is 0, then the new record should be inserted in the DB table. This is how I have framed the stored procedure:
CREATE PROCEDURE RegUsers @FName varchar(50), @LName varchar(50), @UserID varchar(50), @Password varchar(50), @return_value int OUTPUTAS IF EXISTS(SELECT UserID FROM Users WHERE UserID=@UserID) BEGIN SET @return_value=1 END ELSE BEGIN SET @return_value=0 INSERT INTO Users VALUES (@FName,@LName,@UserID,@Password) END
& this is how I am invoking the stored procedure from the ASPX page:
<script runat="server"> Sub btnSubmit(ByVal obj As Object, ByVal ea As EventArgs) Dim sqlCmd As SqlCommand Dim sqlConn As SqlConnection
sqlConn = New SqlConnection("Data Source=MyDBSQLEXPRESS;Initial Catalog=DB;Integrated Security=True") sqlCmd = New SqlCommand("RegUsers", sqlConn) sqlCmd.CommandType = CommandType.StoredProcedure
With sqlCmd Parameters.Add("@return_value", SqlDbType.Int, 4).Direction = ParameterDirection.ReturnValue Parameters.AddWithValue("@FName", txtFName.Text) Parameters.AddWithValue("@LName", txtLName.Text) Parameters.AddWithValue("@UserID", txtUserID.Text) Parameters.AddWithValue("@Password", txtPassword.Text) End With
sqlConn.Open() sqlCmd.ExecuteNonQuery()
If (sqlCmd.Parameters(0).Value = 1) Then lblMessage.Text = "UserID Already Exists!" ElseIf (sqlCmd.Parameters(0).Value = 0) Then lblMessage.Text = "Thanks For Registering!" End If
sqlConn.Close() End Sub</script><form runat="server"><%-- the 4 TextBoxes come here --></form>
When I execute the above ASPX code, if the UserID I entered already exists in the DB table, then ASPX generates the following error:
Procedure or Function 'RegisterUsers' expects parameter '@return_value', which was not supplied.
pointing to the line
sqlCmd.ExecuteNonQuery()
Can someone please point out where am I going wrong?

My userid column in the my db is auto incrementing with a seed of 1 and a step value of 1.
How could I create an output parameter that would return their new user id and then how would i set it to an integer variable.

Hi everyone,
This is the sp i have written which works fine in the sql server management studio when i run it but when i call it from the vb.net web application the output parameters are generated as nothing but the sp return the data from the select statement, so here is the sp followed by vb.net code to access the sp.
This is the Store ProcedureCREATE PROCEDURE [dbo].StaffAuthenticate

@P_message_code int OUTPUT
AS
BEGIN
SET NOCOUNT ON;
Select * From Staff;
SET @IsAuthenticated = 0;
SET @P_message_code = 100;
RETURN END
GOThis is the VB.NET code. Dim ConStr As String = GenericDataAccess.GetConnection(IConnectionStrNames.OAAStaffAuthStr)
Dim Conn As SqlConnection = New SqlConnection(ConStr)
Dim Command As SqlCommand = Nothing
Conn.Open()
Command = New SqlCommand()

Hi,
I have stored some HTML in a table using an attribute defined as a "text" datatype. I use a stored procedure to insert the data and it works fine - I can see the formattede HTML via direct table access uising enterprise manager.
Now I need to call back this data into my vb.net program. So I have created another stored procedure and have tried to out put the field via an output paramater. The output parameter is defined as a text datatype without a field size and the sql assigns the data in a format select @field = dbfield ....
I get a message saying that data of type text cannot be output to the parameter? I will only ever return 1 record and setting up an adapter etc seems overkill. Anyone got a workaround for this?
Thanks,
Rob.

In my ASP.NET page I use a stored procedure that have a parameter declared as OUTPUT...
however...I do not know how to get this OUTPUT to be stored in a ASP.NET-variable...
this is the sp:
CREATE PROCEDURE spInsertNews
@uidArticleId uniqueidentifier OUTPUT,
@strHeading nvarchar(300),
@strAbstract nvarchar(600),
@strText nvarchar(4000),
@dtDate datetime,
@dtDateStart datetime,
@dtDateStop datetime,
@strAuthor nvarchar(200),
@strAuthorEmail nvarchar(200),
@strKeywords nvarchar(400)
AS
SET @uidArticleId = newid()
INSERT INTO tblArticles
VALUES(@uidArticleId ,@strHeading,@strAbstract,@strText,@dtDate,@dtDateStart,@dtDateStop,@strAuthor,@strAuthorEmail,@strKeywords)
my asp code is something like this:
...
SqlCommand sqlcmdInsertNewsArticle = new SqlCommand(insertCmd, sqlconCon);
sqlcmdInsertNewsArticle.Parameters.Add(new SqlParameter("@strHeading", SqlDbType.NVarChar, 300));
sqlcmdInsertNewsArticle.Parameters["@strHeading"].Value = strHeading.Text;
sqlcmdInsertNewsArticle.Parameters.Add(new SqlParameter("@strAbstract", SqlDbType.NVarChar, 600));
sqlcmdInsertNewsArticle.Parameters["@strAbstract"].Value = strAbstract.Text;
sqlcmdInsertNewsArticle.Parameters.Add(new SqlParameter("@strText", SqlDbType.NVarChar, 4000));
sqlcmdInsertNewsArticle.Parameters["@strText"].Value = strText.Text;
...
sqlcmdInsertNewsArticle.Connection.Open();
sqlcmdInsertNewsArticle.ExecuteNonQuery();
sqlcmdInsertNewsArticle.Connection.Close();
How do I do if I want to catch the OUTPUT-parameter (@uidArticleId)?
anyone?

I'm having a terrible time getting a return value from my stored procedure. The sp sets the value and returns it correctly in the query analyzer, but I can't get the calling code - using VB in VS2003 - to read the value. I've tried putting it into an integer, and using a Return, and also putting it into a string, and using an output parameter. Either way: nada. What am I doing wrong????
Here's the sp:
CREATE PROCEDURE sp_HOUSRoomAudits @Result VarChar(1) OUTPUT, @Dorm VarChar(12), @Room VarChar(5), @StuID VarChar(14) AS
DECLARE @Capacity IntDECLARE @Assigned Int--DECLARE @Result VarChar(1)DECLARE @BD BIT
SET @BD=(SELECT Boarding FROM HOUS_StudentMaster WHERE StudentID=@StuID)
SET @Capacity=(SELECT [Student Capacity] FROM HOUS_Rooms WHERE Bldg=@Dorm AND [Room #]=@Room)
SET @Assigned=(SELECT COUNT(PSID) FROM HOUS_StudentMaster a JOIN HOUS_Dorms b ON a.Dormatory=b.Dormitory WHERE b.Bldg=@Dorm AND a.Status='Active' AND a.Room=@Room)
IF (@BD=1 AND @Room='N/A') OR (@BD=0 AND @Room<>'N/A')
SET @Result='3'ELSE IF @Assigned<@Capacity SET @Result='1' ELSE SET @Result='2'
print @Result--RETURN @ResultGO
Here's the calling code; I'm leaving out all the dim's etc down to the output parameter:
Dim Parm4 As SqlParameter = scmdReturn.Parameters.Add("@Result", SqlDbType.VarChar)
Parm4.Direction = ParameterDirection.Output
Parm4.Value = "0"
Try
scmdReturn.ExecuteNonQuery()
strOut = Parm4.Value
Catch ex As Exception
Me.lblProblem.Text = "Failed to execute command, err = " & ex.Message
Me.lblProblem.Visible = True
Finally
scnnReturn.Close()
End Try
Hoping you can help, and thanks!

I'm having a blast.I've been trying to get a sproc to work with 3 imputs and 1 output parameter, first I thought it was something wrong with my asp.net (v2.0) code but after some high pursuit code searching I finally tried out the sproc in QA, still didn't work. can you see what's wrong with this sproc?CREATE PROCEDURE gogogod.sp_user_add@username varchar(24),@password varchar(64),@email varchar(64),@errCode varchar(128) OUTPUTAS IF NOT EXISTS(SELECT username, email FROM tblUser WHERE username = @username OR email = @email ) BEGIN DECLARE @uid uniqueidentifier SET @uid = newID() INSERT INTO tblUser (uid, username, password, email) VALUES (@uid, @username, @password, @email) SELECT @uid AS uID SET @errCode = 'user created' END ELSE SET @errcode = 'User already exists' RETURNfor some reason the sproc asks for a 4th input parameter, I tried just adding " , '' " as a fourth and it 'worked' (i think) I couldn't check if there was an output for the @errcode.any ideas?

The last 3 variables AddressOut, FnameOut, LNameOUT do not return any values.
I am sure that my problem is somewhere in my vb code as if i run the sproc in QA it runs ok and outputs the variables.

I am having problems returning the value of a parameter I have set in my stored procedure. Basically this is an authentication to check username and password for my login page. However, I am receiving the error:
Procedure 'DBAuthenticate' expects parameter '@@ID', which was not supplied.
This stored procedure is supposed to return a -1 if the username is not found, -2 if the password does not match, or the @ID parameter, which is the user ID, if it is successful. How do i go about fixing this SP so that I am returning this output for @ID?
CREATE PROCEDURE DBAuthenticate
(
@UserName nVarChar (20),
@Password nVarChar (20),
@@ID varchar(4) OUTPUT
)
AS
Declare @ActualPassword nVarchar (20)
Select
@@ID = RegionID,
@ActualPassword =regpassword
From dbo.Regions
Where Region = @Username
If @@ID is not null
Begin
if @Password =@actualpassword
Select @@ID
Else
Select -2
End
Else
Select -1
GO

Hi guys,
I know this might be the wrong place to post this, but I thought I would try since all of you are very smart here :).
I have a huge problem with an app that I inherited. It is a VB6 app that used RDO.
I am trying to convert it to use ADO, but the problem I am running into is we have allot of stored procedures with OUTPUT parameter's, so instead of the procedure having a SELECT to pass back the value, it is passed back via the OUTPUT parameter.
With RDO this is done easily with just passing back the parameter to a variable.
I am not sure how to do this with ADO. Please shine some light for me.
Here is an example:
RDO code:
Private rqAddRecord As RDO.rdoQuery
Private rs As RDO.rdoResultset
Set rqAddRecord = SQLServerDB.CreateQuery("", MakeSP("sp_UpdCourier", 11))
With rqAddRecord
.rdoParameters(0) = "I"
.rdoParameters(1) = m.nCourierDeliveryID
.rdoParameters(2) = m.dDeliveryDate
.rdoParameters(3) = m.nCourierServiceID
.rdoParameters(4) = m.nCourierID
.rdoParameters(5) = m.sCourierDepartment
.rdoParameters(6) = m.dTimeStart
.rdoParameters(7) = m.dTimeComplete
.rdoParameters(8) = g.sDatabaseUserName
.rdoParameters(9) = m.dInvoiceDate
.rdoParameters(10) = m.sInvoiceNumber
.Execute
m.nCourierDeliveryID = .rdoParameters(1)
End With
Stored Procedure:
CREATE PROCEDURE sp_UpdCourier
(
@ActionCode char(1),-- (I)nsert, (U)pdate, (D)elete
@CourierDeliveryID intOUTPUT,
@DeliveryDate datetime,
@CourierServiceID tinyint,
@CourierID tinyint,
@CourierDepartment char(5),
@TimeStart datetime,
@TimeComplete datetime,
@ChangedUserID char(8),
@InvoiceDate smalldatetime,
@InvoiceNumber char(15)
)

Hi,
I have a sp like this:
Create PROCEDURE sp_child2 @inp int, @out int output
AS
SELECT @out = @inp * 10
GO
In the report screen i want the following:
A text box which will take the @inp(this will come automatically)
When i click the "view report" the output value should be displayed in the textbox i have in the report.
But the problem i am facing is with the above sp is its creating two text boxes automatically asking for @inp and @out.If i dont give anything in @out text box and press the view report an error is thrown asing me to fill the output box.
Isnt it supposed to be a output value?Am i doing something wrong?
please help...

Hi,I am currently creating an ASP page that returns a recordset of searchresult based on multiple keywords. The where string is dynamicallybuilt on the server page and that part work quite well. However I wantto also return the number of records in the recordset and I can notmanage to get any output parameter working. Even if I assign SELECT@mycount=100 (or SET @mycount=100) in the SP the only value set inmycount is always NULL. I tested various theories (e.g. early exit,order & naming of parameters etc. but I can not make the SP set theoutput parameters - has it anything to do with the execute?). @mycountalso returns NULL if I test it in SQL QA.What's wrong with this SP (as regards mycount):CREATE PROCEDURE dbo.spFindProducts@mycount integer OUTPUT,@whereString varchar (1000)AS--SET NOCOUNT ON--Set a Default value for the Wherestring which will return all recordsif the Wherestring is blankIF @whereString is NullSELECT @whereString = 'AND TblProduct.ProductID is not null'--Declare a variable to hold the concatenated SQL stringDECLARE @SQL varchar(2500)-- AND (((UPPER([TblProduct].[ProductName] + [ProductGroupCode] +[AttributeValue1] +-- [SearchWords] + [tblSupplier].[SupplierCode] + [SupplierDesc]))Like '%screw%'))SELECT @SQL = 'SELECT TblProduct.ProductID, TblProduct.ProductName,TblProduct.ChapterCode, tblProduct.ProductGroupCode' +' FROM (TblProduct LEFT JOIN TblStockItem ON TblProduct.ProductID =TblStockItem.ProductID) ' +' LEFT JOIN tblSupplier ON TblProduct.SupplierCode =tblSupplier.SupplierCode' +' WHERE 1=1 ' + @whereString +' GROUP BY TblProduct.ProductID, TblProduct.ProductName,TblProduct.ChapterCode, TblProduct.ProductGroupCode'SELECT @mycount = 200; -- testexecute (@SQL);-- next line seems to be ignored ?SELECT @mycount = @@rowcount;GOtiaAxel

Is it possible to use stored procedure with output parameter and retrieves the values of that output parameter, in an OLE DB Command within a Data Flow?
What I wanted to do is to get the newly created identity of a row so that I can insert it to the main data set in data flow. I'm not even sure if there is even a much better design to achieve this. I've rummaged the internet but everything I got were all about Execute SQL Task.
