Not sure what happened to my post, it seems to have disappeared. Here we go again. I have a stored procedure that I would like some feedback on, as I feel it may be inefficient as coded:
@ZUserID varchar(10)
AS
SET NOCOUNT ON
DECLARE @counter int
SET @counter = 0
WHILE @counter < 10
BEGIN
SET @counter = @counter + 1
IF EXISTS(SELECT * FROM tblWork WHERE UserID = @ZUserID And LineNumber = @counter)
BEGIN
UPDATE tblWork SET
TransID = Null,
TransCd = Null,
InvoiceNo = Null,
DatePaid = Null,
Adjustment = Null,
Vendor = Null,
USExchRate = Null
WHERE
UserID = @ZUserID And LineNumber = @counter
END
ELSE
INSERT INTO tblWork
(LineNumber,TransCd,UserID)
VALUES
(@counter,'P',@ZUserID)
END
I tried my luck in the Access forum and I've search the web and MSDN for an answer with little luck.
Simply, is it better to update a table via an UPDATE query or Recordset manipulation?
I have read that if you were to update 10,000 records an UPDATE query is more efficient (obviously), but does that transend down to say 1 - 10 updates?
i.e. There are six unique updates I want to make to 6 different rows. Should I code the backend VB to execute 6 different queries or seek and update a recordset?
It's a MS Access XP app with ADO 2.8.
My gut feeling on this is that making 6 update queries is more efficient, both with system resources and record-locking issues; I'd just like another opinion on the matter.
All: I have created a stored procedure on SQL server that does an Insert else Update to a table. The SP starts be doing "IF NOT EXISTS" check at the top to determine if it should be an insert or an update. When i run the stored procedure directly on SQL server (Query Analyzer) it works fine. It updates when I pass in an existing ID#, and does an insert when I pass in a NULL to the ID#. When i run the exact same logic from my aspx.vb code it keeps inserting the data everytime! I have debugged the code several times and all the parameters are getting passed in as they should be? Can anyone help, or have any ideas what could be happening? Here is the basic shell of my SP: CREATE PROCEDURE [dbo].[spHeader_InsertUpdate] @FID int = null OUTPUT,@FLD1 varchar(50),@FLD2 smalldatetime,@FLD3 smalldatetime,@FLD4 smalldatetime AS Declare @rtncode int IF NOT EXISTS(select * from HeaderTable where FormID=@FID) Begin begin transaction --Insert record Insert into HeaderTable (FLD1, FLD2, FLD3, FLD4) Values (@FLD1, @FLD2, @FLD3,@FLD4) SET @FID = SCOPE_IDENTITY(); --Check for error if @@error <> 0 begin rollback transaction select @rtncode = 0 return @rtncode end else begin commit transaction select @rtncode = 1 return @rtncode end endELSE Begin begin transaction --Update record Update HeaderTable SET FLD2=@FLD2, FLD3=@FLD3, FLD4=@FLD4 where FormID=@FID; --Check for error if @@error <> 0 begin rollback transaction select @rtncode = 0 return @rtncode end else begin commit transaction select @rtncode = 2 return @rtncode end End---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I'm having a strange problem that I can't figure out. I have an SQL stored procedure that updates a small database table. When testing the Stored Procedure from the Server Explorer, it works fine. However, when I run the C# code that's supposed to use it, the data doesn't get saved. The C# code seems to run correctly and the parameters that are passed to the SP seem to be okay. No exceptions are thrown. The C# code: SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["touristsConnectionString"].ConnectionString); SqlCommand cmd = new SqlCommand("fort_SaveRedirectURL", conn); cmd.CommandType = CommandType.StoredProcedure; Label accomIdLabel = (Label)DetailsView1.FindControl("lblID"); int accomId = Convert.ToInt32(accomIdLabel.Text); cmd.Parameters.Add("@accomId", SqlDbType.Int).Value = accomId; cmd.Parameters.Add("@path", SqlDbType.VarChar, 250).Value = GeneratePath(); try { conn.Open(); cmd.ExecuteNonQuery(); } catch(Exception ex) { throw ex; } finally { conn.Close(); } The Stored Procedure: ALTER PROCEDURE developers.fort_SaveRedirectURL ( @accomId int, @path varchar(250) ) AS DECLARE @enabled bit, @oldpath varchar(250)
/* Ensure that the accommodation has been enabled */ SELECT @enabled = enabled FROM Experimental_Accommodation WHERE Experimental_Accommodation.id = @accomId
IF (@enabled = 1) BEGIN /* Now check if a path already exists */ SELECT @oldpath = oldpath FROM Experimental_Adpages_Redirect WHERE Experimental_Adpages_Redirect.accom_id = @accomId
IF @oldpath IS NULL BEGIN /* If Path already exists then we should keep the existing URL */ /* Otherwise, we need to insert a new one */ INSERT INTO Experimental_Adpages_Redirect (oldpath, accom_id) VALUES (@path,@accomId) END END RETURN
If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE( ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL, FirstName VARCHAR(50) NULL, LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName) VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) SELECT FirstName, LastName, NULL FROM MYOTHERTABLE
I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.
I'm working on inserting data into a table in a database. The table has two separate triggers, one for insert and one for update (I don't like it this way, but that's how it's been for years). When there is a normal insert, done via a program, it looks like the triggers work fine. When I run an insert manually via a script, the first insert trigger will run, but the update trigger will fail. I narrowed down the issue to a root cause.
This root issue is due to both triggers using the same temporary table name. When the second trigger runs, there's an error stating that a few columns don't exist. I went to my test server and test db and changed the update trigger so that the temporary table is different than the insert trigger temporary table, the triggers work fine. The weird thing is that if the temporary table already exists, when the second trigger tries to create the temporary table, I would expect it to fail and say that it already exists.I'm probably just going to update the trigger tonight and change the temporary table name.
Hi I and using gridview. And binding the data in the code behind.I need to use update command in code behind. How do I achieve this? I protected void lookUP (object sender, EventArgs e) { string strSql, strConn;
System.Text.StringBuilder whereClause = new System.Text.StringBuilder();
Where am I going wrong? I have no idea where to start to look for any incorrect code because it all looks ok! Please help!!! I am entering a record into 5 textboxes - I can see the new record when I open the datagrid view, but when I close the programme and reopen it the record disappears, this code looks ok to me so where is it wrong? Obviously the record is not being written to the database so that when I reopen the programme there is nothing to fill the dataset..........any ideas? Your help is appreciated!!!

In the device emulator when it starts I see two records that were added to the SDF in the VS2008 IDE. I added a third record and after tapping on the Save menu my navigation control shows all three records. I then closed the application. I went to Memory and stopped the form. I went to the File Editor and restarted the application. It only showed the original 2 records. In the File Editor I tapped on the SDF to open it in the Query Analyzer. It also only shows the original two records.
The Dataset appears to be updated, but not the bound table in the SDF. Can any one help? Code is below. bsTEST is the binding SOurce navTEST is my custom Navigation control

Hello,I am writing a stored procedure that will take data from severaldifferent tables and will combine the data into a single table for ourdata warehouse. It is mostly pretty straightforward stuff, but there isone issue that I am not sure how to handle.The resulting table has a column that is an ugly concatenation fromseveral columns in the source. I didn't design this and I can't huntdown and kill the person who did, so that option is out. Here is asimplified version of what I'm trying to do:CREATE TABLE Source (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,ssn CHAR(9) NOT NULL )GOALTER TABLE SourceADD CONSTRAINT PK_SourcePRIMARY KEY CLUSTERED (grp_id, mbr_id)GOCREATE TABLE Destination (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,member_ssn CHAR(9) NOT NULL,subscriber_ssn CHAR(9) NOT NULL )GOALTER TABLE DestinationADD CONSTRAINT PK_DestinationPRIMARY KEY CLUSTERED (grp_id, mbr_id)GOThe member_ssn is the ssn for the row being imported. Each member alsohas a subscriber (think of it as a parent-child kind of relationship)where the first 9 characters of the mbr_id (as a zero-padded string)match and the last two are "00". For example, given the followingmbr_id values:1234567890012345678901123456789021111111110022222222200They would have the following subscribers:mbr_id subscriber mbr_id12345678900 1234567890012345678901 1234567890012345678902 1234567890011111111100 1111111110022222222200 22222222200So, for the subscriber_ssn I need to find the subscriber using theabove rule and fill in that ssn.I have a couple of ideas on how I might do this, but I'm wondering ifanyone has tackled a similar situation and how you solved it.The current system does an insert with an additional column for thesubscriber mbr_id then it updates the table using that column to joinback to the source. I could also join the source to itself in the firstplace to fill it in without the extra update, but I'm not sure if theextra complexity of the insert statement would offset any gains fromputting it all into one statement. I plan to test that on Monday.Thanks for any ideas that you might have.-Tom.

I am trying to perform a simple update to a SQL Server database table and I can't figure out why this simple UPDATE command doesn't work. I am performing the same thing in another page for owner information and it works just fine. It seems that some of my code won't work even though the syntax is correct and there is no reason for it not to work.
I have hardcoded text for some of the fields and the UPDATE code below works but when I try to use the information that may be in the Textbox, the code won't do the UPDATE. Please help me figure out what is going on.
Thanks

Thank you! -Corby-
Hi all My error is as follows: Incorrect syntax near '('.Line 27: acceptOrDeclineFriendship.UpdateParameters.Add("Response", answer)Line 28: acceptOrDeclineFriendship.UpdateParameters.Add("FriendID", friend_id)Line 29: acceptOrDeclineFriendship.Update()Line 30: Line 31: End Sub Bear with me... I have a page where i use a repeater control to list users who have requested to be friends with the currently online user. The 'getFriendRequests' query looks like this: SelectCommand="SELECT * FROM Friends, UserDetails WHERE (Friends.UserID = UserDetails.UserID) AND (FriendID = @UserID) AND (ApprovedByFriend = 'False') ORDER BY Friends.Requested DESC">This works. Within each repeater template, there are 2 buttons, 'Accept' or 'Decline', like this: <asp:Repeater ID="Repeater1" runat="server" DataSourceID="getFriendRequests"> <ItemTemplate> (other stuff like avatar and username etc) <asp:Button ID="accept" runat="server" Text="Accept" commandName="Accept" commandArgument='<%#Eval("UserID")%>' onCommand="Accept_Decline_Friends"/> <asp:Button ID="decline" runat="server" Text="Decline" commandName="Decline" commandArgument='<%#Eval("UserID")%>' onCommand="Accept_Decline_Friends"/> </ItemTemplate> </asp:Repeater> The code-behind (VB) which deals with this is as follows: Protected Sub Accept_Decline_Friends(ByVal sender As Object, ByVal e As CommandEventArgs)
'retrieve id of requestee and the answer accept/decline Dim friend_id As String = e.CommandArgument.ToString Dim answer As String = e.CommandName.ToString
'add the parameters acceptOrDeclineFriendship.UpdateParameters.Add("Response", answer) acceptOrDeclineFriendship.UpdateParameters.Add("FriendID", friend_id) acceptOrDeclineFriendship.Update()
End Sub Since the buttons are being created dynamically, this is how i track 1. the response from the currently logged in user 'Accept/Decline' and 2. who they are responding to (by their uniqueid) This relates to a sqlDataSource on my .aspx page like this: <!---- update query when user has accepted the friendship ----> <asp:SqlDataSource ID="acceptOrDeclineFriendship" runat="server" ConnectionString="<%$ xxx %>" UpdateCommand="UPDATE Friends SET (ApprovedByFriend = @Response) WHERE (FriendID = @UserID) AND (UserID = @FriendID)"> <UpdateParameters> <asp:ControlParameter Name="UserID" ControlID="userIdValue" /> </UpdateParameters> </asp:SqlDataSource> Which is meant to update my 'Friends' table to show that 'ApprovedByFriend' (the logged in user) is either 'Accept' or 'Decline', and record who's request was responded to. I hope this is clear, just trying to suppy all of the information! The error appears to be saying that I have an issue with my code-behind, where i am telling the sqlDataSource above to UPDATE. What I can say is that for each button in the repeater, the 2 variables 'friend_id' and 'answer' are picking up the correct values. Can anyone see any obvious problems here? Any help is very much appreciated as i am well and truley stuck!
hi there, i have been wrestling with this for quite a while, as in my other post http://forums.asp.net/t/1194975.aspx, what someone advised me was to put in try catch blocks ot see whats going on, problem is i have never really done it whit this kinda thing before, and i was wondering if someone could point me in the right direction.
For example where would i put the try catch block in here, to show me if its not working public int getLocationID(int ProductID, int StockLoc) { // Gets the LocationID (Shelf ID?) for the stock column and product id // passed // The SQL will look Something like: string strSQL; strSQL = "SELECT " + " location" + StockLoc + " " + "FROM " + " tbl_stock_part_multi_location " + "WHERE " + " stock_id = " + ProductID;string sConnectionString = "Data Source=xxxxx;Initial Catalog=xxxx;User ID=xxxx;Password=xxxxx"; SqlConnection objConnGetLocationID = new SqlConnection(sConnectionString);SqlCommand sqlCmdGetLocationID = new SqlCommand(strSQL, objConnGetLocationID); objConnGetLocationID.Open();int intLocation = Convert.ToInt32(sqlCmdGetLocationID.ExecuteScalar()); return intLocation; }

I have dataadapter and dataset that reads/writes to SQL tables. I can read. I can create "new" records. However, I have not been able to master the "updating" of an existing row. Can someone provide me specific code for doing this please or tell me what I doing wrong in the code below. The code I using is below. I don't get error, but changes do not get written to SQL dbase. For starters, I think I "not" supposed to use the 2nd line(....NewRow). I think this is only for new row, not updating of existing row - but I don't know any other way to get schema of row. thanks to any who can help
Hi all I have a GridView on an aspx page, that is enabled for editing, deletion and sorting. In the Page_Load event of the aspx page, i add a SqlDataSource to the page, and bind the source to the GridView. When i click the update, or delete button, it makes a PostBack, but nothing is affected. I'm sure this has got something to do with the parameters. First, i tried having the GridView.AutoGenerateColumns set to True. I have also tried adding the columns manually, but no affect here either. The code for setting the commands, and adding the SqlDataSource to the page are as follows: string strConn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; string strProvider = ConfigurationManager.ConnectionStrings["ConnectionString"].ProviderName; string selectCommand = "SELECT * FROM rammekategori"; SqlDataSource ds = new SqlDataSource(strProvider, strConn, selectCommand); ds.ID = "RammeKategoriDS"; ds.UpdateCommand = "UPDATE rammekategori SET Kategoribeskrivelse = @Kategoribeskrivelse WHERE (Kategorinavn = @Kategorinavn)"; ds.DeleteCommand = "DELETE FROM rammekategori WHERE (Kategorinavn = @Kategorinavn)"; Parameter Kategorinavn = new Parameter("Kategorinavn", TypeCode.String); Parameter Kategoribeskrivelse = new Parameter("Kategoribeskrivelse", TypeCode.String); ds.UpdateParameters.Add(Kategorinavn); ds.UpdateParameters.Add(Kategoribeskrivelse); ds.DeleteParameters.Add(Kategorinavn); Page.Controls.Add(ds); SqlDataSource m_SqlDataSource = Page.FindControl("RammeKategoriDS") as SqlDataSource; if (m_SqlDataSource != null) { this.gvRammeKategorier.DataSourceID = m_SqlDataSource.ID; } As mentioned - no affect at all! Thanks in advance - MartinHN
SSIS seems to automatically set the metadata type and for "typed" sources like database and XML connections it seems to take whatever the source column datatype is. If you use a cast or convert in the your source SQL query, it will not change the datatype of the metadata. This becomes an issue when doing things like merge joins on data from different sources and the join columns are different types (e.g. a ZipCode in one system is a varchar and it is an int in another system). I've been working around the issue by editing the XML code and changing the datatype there. Is there any way to do this through the GUI?

Hi, I am a newbie in using ASP.NET 2.0 and ADO.NET. I wrote a hangman game and want to record statistics at the end of each game. I will create and update records in the database for each authenticated user as well as a record for the Anonymous, unauthenticated user. After a win or loss has occurred, I want to programmatically use the SQLDataSource control to increment the statistics counters for the appropriate record in the database (note I don't want to show anything or get user input for this function). I need a VB.NET codebehind example that will show me how I should set up the parameters and update the appropriate record in the database. Below is my code. What happens now is that the program chugs along happily (no errors), but the database record does not actually get updated. I have done many searches on this forum and on the general Internet for programmatic examples of an update sequence of code. If there is a tutorial for this online or a book, I'm happy to check it out. Any help will be greatly appreciated.
