I have a table tblnetwork on which identity property
is defined on column networkid.
When I issue the following command new record is getting inserted into
tblnetwork and identity column is getting incremented properly.
But, I am not able to get the @@identity value
It is returned as NULL.
I'm trying to return the identity from a stored procedure but am getting the error - "specified cast is invalid" when calling my function. Here is my stored procedure - ALTER Procedure TM_addTalentInvite @TalentID INT AS Insert INTO TM_TalentInvites ( TalentID ) Values ( @TalentID ) SELECT @@IDENTITY AS TalentInviteID RETURN @@IDENTITY
And here is my function - public static int addTalentInvite(int talentID) { // Initialize SPROCstring connectString = "Data Source=bla bla"; SqlConnection conn = new SqlConnection(connectString);SqlCommand cmd = new SqlCommand("TM_addTalentInvite", conn); cmd.CommandType = CommandType.StoredProcedure; // Update Parameterscmd.Parameters.AddWithValue("@TalentID", talentID); conn.Open();int talentUnique = (int)cmd.ExecuteScalar(); conn.Close();return talentUnique; } Any help you can give me will be greatly appreciated thanks!
I have a stored procedure that inserts a record. I call the @@Identity variable and assign that to a variable in my SQL statement in my asp.net page.
That all worked fine when i did it just like that. Now I'm using a new stored procedure that inserts records into 3 tables successively, and the value of the @@Identity field is no longer being returned.
As you can see below, since I don't want the identity field value of the 2 latter records, I call for that value immediately after the first insert. I then use the value to populate the other 2 tables. I just can't figure out why the value is not being returned to my asp.net application. Think there's something wrong with the SP or no?
When I pass the value of the TicketID variable to a text field after the insert, it gives me "@TicketID".
Hello all,I have a sqldatasource that inserts data to the database but I want to get the ID from an Identity field after I am done inserting the data. How can I best do that? I'm not using a stored procedure to do this. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:onepduConnectionString %>" InsertCommand="INSERT INTO [tblaccounts] ([fname],[lname], [address], [city], [state], [zip], ,[phone],[credits]) VALUES (@fName,@lname, @address, @city, @state, @zip, @email, @phone, @credits)> <InsertParameters> <asp:FormParameter Name="fname" FormField="FirstNameTextBox" Type="String" /> <asp:FormParameter Name="lname" FormField="LastNameTextBox" Type="String" /> <asp:FormParameter Name="address" FormField="AddressTextBox" Type="String" /> <asp:FormParameter FormField="cityTextBox" Name="city" Type="String" /> <asp:FormParameter FormField="stateTextBox" Name="state" Type="String" /> <asp:FormParameter FormField="zipTextBox" Name="zip" Type="String" /> <asp:FormParameter FormField="emailTextBox" Name="email" Type="string" /> <asp:FormParameter FormField="phoneTextBox" Name="phone" Type="string" /> <asp:Parameter Name="credits" DefaultValue=0 /> </InsertParameters> </asp:SqlDataSource>
Hi All: I have what I'm sure is a common scenario...I have a table to track pageviews of a form, and which also tracks when a person viewing the form submits it. The table has three fields: an INT identity/PK field, a DATETIME (default getdate()) field, and a BIT field with default "false". When the page is viewed, I insert a record into the dB: Protected Sub Page_load(ByVal src As Object, ByVal e As EventArgs)
conn = New SqlConnection("Server=myserver;Database=mydb;User ID=user;Password=password;Trusted_Connection=false;") If Not IsPostBack Then AddTrack() End If End Sub Sub AddTrack()
Dim myCommand As SqlCommand Dim insertTrack As String insertTrack = "Insert PageTracker (submitted) Values (0)"myCommand = New SqlCommand(insertTrack, conn) myCommand.Connection.Open() Try myCommand.ExecuteNonQuery()tempTxt.Text = "<br>Ticked</b><br>" & insertTrack Catch ex As SqlException tempTxt.Text = ex.Number.ToString()
End Try myCommand.Connection.Close() End Sub And if I view the page, the record is inserted into the table. But now I need to know the value of the identity field, so when the form is submitted, I can update the field "submitted" from "0" to "1". The way I would do it in ASP is to add a "SELECT @@identity" to the query, and get the value using RS.nextrecordset. How would I do this in .NET? or is there a better way for me to do this?
I am currently using IDENT_CURRENT to return the Id of a new row in SQL 2000, but I am looking for a similar way to do this in SQL 7. Ihave no experience with SQL 7
I am inserting a record by calling a stored procedure in my asp.net code. I need to return the identity field from the insert to use elsewhere in my code. I have found many things regarding this but nothing has worked.
Here is the last part of my stored procedure. BTW, I have added Scope_Identity to the end of my sp and when I open my sp up, it is not there...not sure what that is about. I guess my main problem is what command do I use in ASP.net to execute the sp AND hold my returned value...
Hi all i'm trying to get the identity field after inserting into db, what am i doing wrong? thanks a lot my sproc: CREATE PROCEDURE ng_AddCotacao(...@Codigo_cotacao int OUTPUT)ASBEGINSET NOCOUNT ONINSERT INTONegocios_cotacoes(...)VALUES(...)SELECT @Codigo_cotacao=SCOPE_IDENTITY()SET NOCOUNT OFFENDGO

I have a createStudent SProc. When this is called it calls a createContact SProc. This in turn calls a Create Address Stored procedure. Now when I create the address, an Identity column automatically creates a new Identity for me. I need to return this value back to the calling stored procedure. I know how to return a value and all, however, how to I get the identity just entered (the corresponding identity) reliably? I know that select MAX <Identity> could suffice in this case, but is flawed as if someone was to add another object near the same time we could get the wrong identity returned...
I am storing product information in a SQL Server database table; the product information has no unique fields so I have created an Identity field called ‘uid’. Is there a way of querying the table to find out what value will be given to the next ‘uid’ field before the next record is written to the table? I need to use this as a FK in other tables.
Hello, I have a C# application that adds records to a SQL Server database using a query something like this one:
INSERT INTO table_name (first_name, last_name, date_added) ('john', 'smith', '1/1/2005 12:00:00pm') ; SELECT SCOPE_IDENTITY() AS [Scope_Identity]
This works fine unless there's already a John Smith in the database. When that happens, Scope_Identity is null even though the date_added is different. About half the time the record is added even though Scope_Identity is null. I've added code to notify me when this happens, but it's a pain in the neck to re-run my import utility for individual records.
(The table I'm adding to does have a autonumbered key field)
The code below returns the members who have accounts that are inactive, and works correctly. It returns the memberid, but returns null values for the barcode values. I am explicitly looking for unmatched rows, i.e. the LEFT OUTER JOIN will return joined member-address rows which do not have a matching account, according to the ON conditions, and these are the ones I want because of that WHERE condition. Therefore account.barcode will always be NULL too.
Is there to perform the same query and return account details? I have tried running a query to return just the memberid values and then perform a second query to match the account details, but this is very ineffecient and slow.
select member.memberid, account.barcode FROM member INNER JOIN address ON address.MemberID = member.Memberid LEFT OUTER JOIN account ON account.Memberid = member.MemberID AND account.enddate >= current_date AND account.closed = 0 WHERE account.Memberid is null AND member.isDeleted = 0

Thanks for any help oradvice.
i recently found a little error in a stored procedure that was included in a project handed over to me....
the sp was rather simple. it just inserted a record into a table and returned the identity and the timestamp as follows
IF @@ERROR>0 BEGIN SELECT @int_InterventionID = 0 RETURN @@ERROR END ELSE BEGIN SELECT @int_InterventionIDReturned = MAX(InterventionID) FROM tblIntervention SELECT @ts_TimestampReturned = [Timestamp] FROM tblIntervention WHERE InterventionID = @int_InterventionIDReturned SELECT @int_InterventionID = @int_InterventionIDReturned, @ts_Timestamp = @ts_TimestampReturned RETURN 0 END
i figured that it should be using @@Identity for the interventionIdentity rather than max(InterventionID)
so i changed to...
IF @@ERROR>0 BEGIN SELECT @int_InterventionID = 0 RETURN @@ERROR END ELSE BEGIN SELECT @int_InterventionIDReturned = @@IDENTITY SELECT @ts_TimestampReturned = [Timestamp] FROM tblIntervention WHERE InterventionID = @int_InterventionIDReturned SELECT @int_InterventionID = @int_InterventionIDReturned, @ts_Timestamp = @ts_TimestampReturned RETURN 0 END
it returns the @int_InterventionIDReturned but the timestamp now comes back as null??? why??
how can i ensure that i always get the timestamp of the record it has just inserted
i have 2 stored procedures: a delete and a select. the delete sp returns the rowcount properly. the select returns null. the code for both sp's is extremely simple and extremely similar. when i execute the select sp in server management studio the rowcount shows a 1 as expected. but the calling method gets null. SP Code ALTER PROCEDURE [dbo].[RetrieveEmployeeKeyFromAssignmentTable] @assignmentPrimaryKey int, @rowCount int OUTPUT AS BEGIN SET NOCOUNT ON; SELECT employeePrimaryKey FROM assignmentTable WHERE primaryKey = @assignmentPrimaryKey; SET @rowCount = @@RowCount; END c# code SqlConnection conn = GetOpenSqlConnection(); if (conn == null) return true; SqlDataReader reader = null; SqlParameter p1 = new SqlParameter(); SqlParameter p2 = new SqlParameter(); try { SqlCommand command = new SqlCommand(); command.CommandText = "RetrieveEmployeeKeyFromAssignmentTable"; command.CommandType = CommandType.StoredProcedure; command.Connection = conn; p1.ParameterName = "@assignmentPrimaryKey"; p1.Value = assignmentPrimaryKey; p2.ParameterName = "@rowCount"; p2.Direction = ParameterDirection.Output; p2.Value = 0; command.Parameters.Add(p1); command.Parameters.Add(p2); reader = command.ExecuteReader(); if (p2.Value == null) //always true any suggestions would be appreciated. thanks. matt
I have a simple table on my webpage which shows data from my database. It all worked fine apart from one part. I wanted the select statement to select only NULL values from a column, as these are classed as open queries. Once I have closed the query a 0 or 1 will automatically be posted and will no longer have a NULL value. I have a simple select statement (which I will post on here when I log in with my work computer) and at the end I have a WHERE Column = NULL. I have also tried WHERE column <> 0.0 AND column <>1.0 and that did not work. If I only did WHERE column <> 1.0, i only get the 0.0 results and none of the NULL results, but if I have no WHERE statement I get all the results including the NULL values.
Using SQL2000. I want to return the # of columns with non-nullvalues. Here's my query so far:selectcase when Dx1 is not null then 0 else 1 end +case when Dx2 is not null then 0 else 1 end +case when Dx3 is not null then 0 else 1 end +case when Dx4 is not null then 0 else 1 end as DxCountfrom tblClerkshipDataCleanwhere PalmName = @PalmNameThere are 7 rows for the particular PalmName I'm using. The queryreturns a result of 7. However, there are 25 values in Dx1 thru Dx4so the query should be returning 25.What am I doing wrong here? Thanks in advance.
I have a SQL 2005 clustered server which is returning a Null value for @@servername. I find the server entry in sysservers. I have replication configured on this so i am not able to do a Sp_dropserver & sp_addserver as this acts as a publisher. The configured merge repication stopped working because of this issue and I am not able to delete replication as the the delete option uses @@servername which returns a null value. So I am struck in a loop.
I am trying to insert a record to based on the source below, however the GUID of GiftOcc_ID is being returned as zero's so the first record can be added but as it is defined as the primary Key and uniqueidentifier the next record fails with a duplicate entry. Basically how do I ensure that the GUID is created and not nulls. As you can see I am trying to use Newid() which I have inserted as a default value but that does not work. Also as it is a unique identifier the "is identity" is not available
Protected Sub CreateGiftOccasion(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click Try Dim null As New Nullable(Of Integer) Dim da As New DataSet2TableAdapters.Gift_OccasionTableAdapter Dim GiftOcc_ID As Guid da.Insert(newid(), Occ_Type_Text.Text, Occ_Desc_Text.Text, Calendar1.SelectedDate, Calendar2.SelectedDate, 1) Catch ex As Exception
I'm still having issues with this despite my attempts to resolve. I even have "with exec as dbo" in my sproc, and and "exec as dbo" in my execution, but still the encrypted data returns nulls when I exec as a user other than DBO. Below is precisely what I have done. All ideas are welcomed.
TIA, ChrisR

I've a package that has a excel source. But i'm having a strange problem with it. One of the columns in the source file have a lot of null values but not all of them. But when i run the package a put a data viewer right after the source and i can see that it's showing that the few fields that should have values are also null. I've tried a lot of things but they didn't work. I need some help and fast if possible. Example: Source file.xls Name Grade OtherGrade John 30 30.23 In the DataViewer Name Grade OtherGrade John 30 NULL
Hi there ; This Problem is goin to make me crazy! I've got a table with couple of fields, 2 of them are DateTime, in Sql Express 05 . I used asp.net 2.0 to insert datetime values, directly, using sth like DateTime.Now.ToString() . i use 2 selects as follows : 1)select * from X where Date1='8/9/2006 11:17:41 AM' 2)select * from X where Date2='8/9/2006 11:17:41 AM' #1 is OK, but the second one returns a row with all columns set to NULL . (X is the name of the table) Thanks in advance
I have a form with two date fields that the user will submit their requested vacation time off with. When they insert it, I am trying to say find the difference between the request_start_date and request_end_date in days MINUS any of the days they would already have off like weekends or holidays that are included in another table. Everything inserts okay, but I am getting null for the request_duration. If I put dates in quotes and run the query it comes back with the right results. If I put the dates in the form and submit it, I get Null for the request_duration. Thank you in advnace for any help on this!
