DataSource Controls :: Returning Primary Key Of New Database Row
Jul 9, 2010
In my application, users fill out a form to submit a "Job Request" - once they submit the form it is stored as a new row in a table in the Sql database. Each "Job Request" that is submitted is given a "JobID" which is a number and also the primary key of the new row in the database (the number is generated by the database). Once the users hit the "submit" button, I'd like to return the value of the "JobID" (the primary key) so that the user can know what it is. How would I achieve this? In the future, I will have to expand the application so that the users would be able to edit an older "Job Request" and get a similar JobID number (so if before it was 1234, the new one would be 1234-1 or something like that), so this is not simply a matter of searching for the highest number in the primary key field in the table and returning that. I'm using Sql for my database and writing in VB.
Let's say I have a table that holds information about books, with a column called bookid as a primary key with auto increment of 1. When I create a couple of records, it assigns 1 to the first row and 2 to the second row for the bookid column. If I delete the second row and enter another row, even though table now only has 2 records, the primary key column says 1 and 3 for their bookids. Is it possible to change back the bookid of the second record from 3 to 2 or is it just server assigned and can't be changed.
Yes..i know this is ASP.NEt forums but the SQL server doubt i will be going to ask is related to ASP.NET
I have a table 'a' in my database where i store User information - each time they visit the website a new record is added
so in a high traffic website - the information will be collectively huge(i dont care about this as i have too much of disk space)
but the problem here is with the primary key - I want a datatype of the primary key which should never end Bigint can store some zillions of records but it finally ends... how will i be able to accomplish it.
My codes below are to insert a new data into the database. The thing is, this code can insert the primary key(DeviceID) into the database automatically but I cant seem to find the code to insert the primary key into the database. point me the statement that insert primary key(DeviceID)..
This is the snippet of the submit button event
Protected Sub SubmitDevice_Button_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitDevice_Button.Click If Session("canUploadBool") = False Then ClientScript.RegisterStartupScript(Me.GetType, "canuploadScript", "") Exit Sub End Dim insertNewProcess As String = "INSERT INTO Device_Table(" Dim deviceColumn As String = "DeviceRevision, CustomerName, CustomerCode, CustomerResponsibleEngineer, Date, DevicePartNumber, PackageType" Dim deviceValue As String = ") VALUES ('01', '" + CustNameDropDownList.SelectedValue.ToUpper + "', '" + CustCodeLabel.Text + "', '" + CustomerResponsibleEngineerTextBox.Text.Trim.ToUpper + "', '" + Format(Now, "dd-MMM-yyyy").ToUpper + "', '" + DevicePartNumberTextBox.Text.Trim.ToUpper + "', '" + PackageTypeTextBox.Text.Trim.ToUpper + "'"
I am using a FormView to populate data, then inserting it using a LinqDataSource. The primary key is an autoincrementing identity. I'd like to handle the ItemInserted event to update some other tables, but I cannot find how to get the primary key of the newly inserted record. The insert happens fine, but nothing for the PK.
I realize I can change to using a SPROC, or change to creating the new row and doing the insert myself, but I'd prefer to continue with the LinqDataSource's automatic insert.
I am using LINQ Expression to insert records in SQL Table. My Table dosen's have any Primary Key Field. Whenever I Am trying to Insert Records in Table using LINQ Expression, this always occurs an Error that 'the Table You are using to insert Dosen't Have Any Primary Key Field.
How I Will Insert Records Without Having Primary Key ?
When a user creates an account for my web application using the create user wizard additional steps have been added to take more details and store them in another table. Now this tables primary key is set to uniqueidentifier, is it possible to have that unique identifier automatically generated when the query is run to insert a new row for a new user?
I have started my new mvc project with entity framework,Must say it is very diffcult to work with entity framework.
"I am trying to create new custom entity in .edmx file,Now i have made one column as Entity key,Which is already entity key another entity set."
"Error 3033: Problem in Mapping Fragment starting at line 3081: EntitySets 'Entityset name' and 'Entityset name' are both mapped to table 'Entityset name'. Their Primary Keys may collide."
how can i retrieve the all foreign keys against a single primary key. i mean to say that if a table contain a primary key then it becomes as foreign keys in which tables.
i want to take that nam of that tables and on the base of that tables then i am to delete from all the entries. e.g: if a primary key's column entry deleted then all foreing key entries should also be deleted.
there are 988 tables in a single database. it can't be possible to go for each table to setup foreign key to ON DELETE CASCADE.
.can it have any way to delete against foreign key priority wise? mean to say that parent table contain primary key, child table contain foreign key , now there is another child table which dependent previous child table. then how can i delete all record against it?
i want to do it from programatically. i am using sql server 2005
i have completed this till to that , it retrieves all foreign keys but how to delete now on the base of priority.
Region ( ID int, Name varchar(50), Description varchar(51) )
One thing I can use is to retrieve the max(ID) from region and store it in a variable and increment the variable sequentially and insert. But, if any other user inserts a record while I am executing this script then max(id) might clash with the id inserted with other user causing my script to fail.
Is there any other option to insert record sequentially base on the highest number in the table.
I have a textbox that takes an integer value, and a submit button that when clicked passes the value to a detailsview to display the database record at that index.
What I'd like to do is, when the button is clicked, compare the number to the keys in the detailsview's datasource so that if the record ID doesn't exist, I can display a label telling the user that the ID# doesn't exist.
How would I go about doing this? Is there some sort of compare method for the datakeynames property?
I call this stored procedure with a dataset. It always returns a 0 but should return a 1 or 2. Does anybody know why it isn't returning a 1 or 2.
ALTER PROCEDURE dbo.sp_InsertLinkVote @LinkId int, @LinkVoter nvarchar(50), @LinkVotesDateTime datetime, @LinkVotesGoodBad bit AS /* SET NOCOUNT ON */
If EXISTS (SELECT * FROM LinkVotes WHERE LinkId=@LinkId and LinkVoter = @LinkVoter )RETURN 1 ELSE INSERT INTO dbo.LinkVotes (LinkId,LinkVoter,LinkVotesDateTime,LinkVotesGoodBad)VALUES (@LinkId,@LinkVoter,@LinkVotesDateTime,@LinkVotesGoodBad)RETURN 2
Here is were a call it in my code behind. Dim VoteCheck As Integer Dim InsertVote As New DataSetStoredProceduresTableAdapters.QueriesTableAdapter VoteCheck = InsertVote.sp_InsertLinkVote(LinkId, User.Identity.Name, DateAndTime. Now, True) '0 is a good vote. If VoteCheck = 0 Then
It seems to insert and not insert correctly, I just cannot get it to return the correct value.
I am developing a page in ASP.Net where I have the user enter a letter into a textbox. They then click a submit button and I all of the userids that start with that letter are to be displayed. So I need the SP to go through the database and match first letters with what was entered. Here is what I have as my code for the SP:
CREATE PROCEDURE dbo.exp2 @testchar Char(1) declare @flag as char(2) set @flag = @testchar + '%' select userid from ex_database where userid like @flag
iam using asp.net2.0 with c# with sql server 2000 when iam executing the procedure in local system it is working fine.but when iam executing in client system procedure returns null value, i have checked all connection string , and session value all are working
when i bind first time page (10) records then primary properly bind with records and when my next 10 records load using lazy loading then the primary key not change it shows 1st records primary key
check the below code in which i am assigning assetid (primary key) but its not assigning properly...
function OnSuccess(response) { //alert('testing'); var xmlDoc = $.parseXML(response.d); var xml = $(xmlDoc); pageCount = parseInt(xml.find("PageCount").eq(0).find("PageCount").text()); var customers = xml.find("AssetSummary");
I'm lost as to where to look next. Here is a sample of what I'm doing:
[Code].... The related tableadapter insert statement was autogenerated by VS2008:
INSERT INTO [ProductCycleCountItem] ([ProductCycleCountLocationID], [ProductID], [CountOnly], [Status]) VALUES (@ProductCycleCountLocationID, @ProductID, @CountOnly, @Status); SELECT id, ProductCycleCountLocationID, ProductID, CountOnly, Status FROM ProductCycleCountItem WHERE (id = SCOPE_IDENTITY())
With multiple users it's as if it was returning @@IDENTITY instead of SCOPE_IDENTITY(). The table will look like this:
id Location product
1 A 5321
2 A 8273
3 B 2827
4 A 1743 The returned dataset will look like this:
id Location Product
1 A 5321 2 A 8273 3 A 1743
Is it maybe a SQL Server (2005) setting that's incorrect?
