DataSource Controls :: Using NewId() To Identify Current Inserting Record And Affect All Other Records In Table?
Apr 27, 2010
I've got a sp as below:
The functionality I want to achieve is that when isHomePageFeatured is checked then this record is set to 1 for that column and for all the other records in the table it is set to 0.
This is fine for update as I can use the property Id to compare against, but for the newly inserted record it doesn't yet have a propertyId so I wondered if using newID() to affect all other records would have the same affect.
I have to retreive all records from a table except 1 record. For example: I give example from default database in SQL ie "master" In "master" DB we have "spt_values" table. Now if I want to retreive all records from spt_values table except 1-1 record of type = A and type = B. To retreive all records its a simple query "Select * from spt_values where type in ('A','B')" -- this will returns 16 records. Now I want to retreive all record except 1-1 record left in each type, so it will return 14 records in result.
I am creating an album using the following stored procedure, which returns the primary key for the newly created record:
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[fpa_sp_albums_update_insert] @album_id int, @album_name nvarchar (50), @album_descr nvarchar(250), @album_img_cover_id_FK int, @album_creation_date date AS If @album_id > 0 UPDATE [fpa_albums] SET album_name=@album_name, album_descr= @album_descr, album_img_cover_id_FK = @album_img_cover_id_FK, album_creation_date = @album_creation_date Where ((album_id = @album_id)) Else INSERT INTO [fpa_albums] ( album_name, album_descr, album_img_cover_id_FK, album_creation_date) VALUES ( @album_name, @album_descr, @album_img_cover_id_FK, @album_creation_date) Return SCOPE_IDENTITY();
I execute the above stored procedure using the SQLHELPER. The VB.NET code for the page is as follows:
[Code]....
However, the createdAlbumID always shows -1 instead of the id for the newly created album.
What is the best method in T-SQL 2008 for extending a table's records with the criteria of 'repeating' all fields but the Primary KEY e.g. Consecutive Date for the previous n Records.
So you have for example 7 records (Easy...2 Fields. Date and nvarchar) with th Date runing from Jan-01 to Jan-07
We want to extend the table by 21 records...so
Record 1,8,15,22 will look identical apart from the DateField.
Record 2,9,16,23 will look identical apart from the DateField. etc...etc..
I have tried a number of methods ...all coming up short....
Im trying to get the ID out of the record that i'm inserting using scope_identity. I've add the following line of code to the Insert statements in the sqldatasource - SET @insID = Scope_Identity() I've add the following line to the Insert parameter list
I now want to insert a number records into the database using the following:
Dim insID As Object = e.Command.Parameters("@insID").Value ' gets out latest ID Dim ordernumber As String = "CX" & insID.ToString & DateTime.Now.DayOfYear.ToString sqlOrders.InsertParameters("orderNumber").DefaultValue = ordernumber sqlOrders.InsertParameters("orderDate").DefaultValue = DateTime.Now sqlOrders.InsertParameters("customerID").DefaultValue = userID sqlOrders.InsertParameters("productID").DefaultValue = productID sqlOrders.InsertParameters("totalPrice").DefaultValue = "0.00" sqlOrders.InsertParameters("status").DefaultValue = "Paid"
I currently have this code in the SQLDataSource_Inserting sub but the first line only works once the record is inserted. How can i get the ID out as im inserting the parameters?
I have the logged-in user's Guid stored in a session variable. My understanding is that when the Guid is passed to the session variable it becomes a string. When I use the detailsview control I have to convert the session variable back to a guid and I've been doing it like this and it seems to work fine:
e.values("UserId") = session("LoggedInUserId") Dim UserId as Guid = New Guid()
When I try to use the Insert() command after the following:
I get an "InvalidCastException" error with the comment "Conversion from type 'Guid' to type 'String' is not valid." I'm assuming the session variable needs to be converted to a type Guid since that's what I've had to do with the Detailsview control. I've tried a few different ways of converting the session variable back to a Guid so the insert command will work, but no matter which method of conversion I try I get errors such as "value of type system.guid cannot be converted to 'string'. I'm confused because I thought I was supposed to convert it from a string to a Guid. The "UserId" parameter is a non-primary key uniqueidentifier in the database.
I'm a beginner with ASP.NET. I'm using SQL Server2005 Management Studio. The problem I facing is arises when I tries to run any query,even the simplest, it doesn't identifies the table. as below:
I want to insert a large amount( approx 7000 records) of data into a table, My scenarios is that i need to check whether the record already exists then it will not insert it. Currently i am using a stored procedure for this which gets called for each record.
IF EXISTS(SELECT 'True' FROM MYTABLE WHERE ID = @ID) BEGIN
--This means it exists, return it to ASP and tell us
SELECT 'This record already exists!' END ELSE BEGIN
--This means the record isn't in there already, let's go ahead and add it
SELECT 'Record Added' IF EXISTS(SELECT 'True' FROM [Aadil].[dbo].[SharePointSitesData] WHERE ID <> @ID)
I'm having a problem when two or more users simultaneous work on a webpage and provides info to create a new record in my database. the issue is that for some reason, their entries get mixed up and the wrong data gets commited to the database, how can i fix this. All the webpages i browsed for help provide optimistic concurrecny on updaing/deleting existing records, not creating new ones.
I also turned off SessionViewState, but I don't think it helps.
I'm not using a ObjectSource Control, i'm creating new instances of the BLL Classes in my code as I need. Should I null the objects after I use them? They are only created in the scope of a method, so it should essentially dispose of the object when the method completes.
I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint() { int counter = 0; string strSql = "select count(*) as ID from tblEnergy where ID=?"; OdbcCommand com = new OdbcCommand(strSql, con); com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue); OdbcDataAdapter oda = new OdbcDataAdapter(com); DataTable dt = new DataTable(); oda.Fill(dt); if (dt.Rows.Count == 0) { lblID2.Text = "1"; } else { counter = dt.Rows.Count; counter = counter + 1; lblID2.Text = Convert.ToString(counter); } }
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?
I have an entity model, in which I have a table per type inheritance. Is it possible to perform an insert using ado.net dataservice and asp.net ajax library? I was trying the following client code :
dataContext.insertEntity(childData, "Parent");
I was getting this response from server : Error processing request stream. Type information must be specified for types that take part in inheritance.
I am in a serious trouble right now, i wanted to know that how to write a query in LINQ to SQL to retrieve identity column's current value before inserting any value.
I need this cos i m building a windows app n i need to display this value before inserting a record. I have tried DataContext.ExecuteCommand('DBCC CHECKIDENT (Tablename)') but it returns the number of rows modified.
I'd like to use sql to select top (#) random row into another table, but it inserts the same record a few times sometimes. I want to avoid duplicates to be inserted, what shall I do?
what I've got for now is
INSERT INTO CompWin (PrizeID, EntryID, UserID) SELECT TOP (50) PrizeID, EntryID, UserID FROM CompEntry ORDER BY NEWID()
I've created a table with a userId column of type uniqueidentifier, and have set that column as the primary key. In the column properties, under the Default Value or Binding, I've put (newid()). I thought that this would create a new uniqueidentifier if no value is specified in the insert statement.
However, when I try to add a new row in the table data view and leave the userId blank, it does not let me add the row. It gives me an error saying that the value cannot be NULL (since it is a primary key), however I had deliberately left it NULL so that it would add a new value by calling newid(). Have I made a false assumption?
My insert is adding a record to the database in the call to the stored procedure in SQL Server, but a -1 is returned - Shouldn't it return 0 if the insert/update was successful?
I have created table into database dynamicaly,while inserting records into that dynamic table i faced problem.
The name "STD000001" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted. this error occured.
I created dynamic table by ,
declare @STUDENT_Table varchar(50) set @STUDENT_Table = [dbo].[GetStudentTable](@SchoolID) exec (@cmd) [code]....
this stored procedure.....
Should i give any permission while creating dynamic table.
How to start at a specific record and returning only the next 5 records with T-SQL command
[Code]....
That is my concatenated SQL statement but it obviously does not work because it only looks at the top 5 records in the entire table instead of what I intended which would be to look at the top 5 records starting with the record where PostNumber equals the value of lastPost. I have been searching for a T-SQL statement that will allow me to do this but I can't find one.
Based on the scheduled meeting, read all users from table #1 and add their info in the table # 3 with the MeetingID (which I can get from the UI, because it will happen when they create the meeting).
I have been browsing about it, but so far, I couldn't find a good source of info to start with.
I have two tables cust and order_cust cust table have cust_id, name, addr, zip columns and order_cust have order_id and cust_id columns I take input from user for cust table i.e. name, addr, zip... the cust_id is an IDENTITY column so generates the value automatically Now I want to insert the last generated cust_id into order_cust (order_id is also an IDENTITY column)
I am having trouble inserting data into the table using dataset..following is my code:
[Code]....
The m_id is a primary key..I want to auto-increament it everytime a data is inserted into the table so I have configured (isIdentity) to Yes and Identity increament to "YES"..I don't know if its right or not..I already added some data manually into the table but now I want to add more data using the above code..but its not working..
