OLE DB Command Not Updating
May 24, 2007
I have a data flow task, and in that is an OLE DB Source that upon success, connects to an OLE DB Command. The OLE DB Source runs a sql command from a variable. (I've tested the sql; it parses and returns values.) The OLE DB Command is a very simple update sql statement with one column mapping. When I execute the task, it says it is successful, but when I check the table, nothing has been updated. I have ensured the connection is successful, and I am connecting to the correct db. Any suggestions would be helpful! Thanks!

I wrote a sproc which does four things:
1. It looks at an option master to see if the record exists before inserting a new one
2. If the record is not there it inserts the optino record
3. Once the record is inserted I have to run a CASE statement on the record to determine its level
4. Once the level is determined, the record needs to be updated with the correct level.
1-3 work fine (when run without the update command).
However, even though I set a criteria, UPDATE still updates and not the one records.
Any idea why? set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO

I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
Any suggestions?

Hi All,
i am using a OLE DB Source in my dataflow component and want to select rows from the source based on the Name I enter during execution time. I have created two variables,
enterName - String packageLevel (will store the name I enter)
myVar - String packageLevel. (to store the query)
I am assigning this query to the myVar variable, "Select * from db.Users where (UsrName = " + @[User::enterName] + " )"
Now in the OLE Db source, I have selected as Sql Command from Variable, and I am getting the variable, enterName,. I select that and when I click on OK am getting this error.
Error at Data Flow Task [OLE DB Source [1]]: An OLE DB error has occurred. Error code: 0x80040E0C.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E0C Description: "Command text was not set for the command object.".
Can Someone guide me whr am going wrong?
myVar variable, i have set the ExecuteAsExpression Property to true too.
Please let me know where am going wrong?
Thanks in advance.

Hi. I am writing a program in C# to migrate data from a Foxpro database to an SQL Server 2005 Express database. The package is being created programmatically. I am creating a separate data flow for each Foxpro table. It seems to be doing it ok but I am getting the following error message at the package validation stage:

Hi, I'm new to ASP.Net quite new to C# (My first attempt at a database website) and am trying to get a button to add "1" to "int" value called "Comments" a each time its pressed basically counting each time a comment is added. I also only wnat it to affect the row where "ModID" in my database is equal to the query string "ModID" I'm using on the page. I cannot find any tutorials so this is my best guess so far. This is probably a Noobie type stupid question but I'm stuck. This is the code I have so far for my Button_Click event: protected void Button_Click(object sender, EventArgs e){ SqlDataSource CommentCountDataSource = new SqlDataSource(); CommentCountDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["Main_Site_DatabaseConnectionString1"].ToString(); CommentCountDataSource.UpdateCommandType = SqlDataSourceCommandType.Text; CommentCountDataSource.SelectCommand = "SELECT (ModID, DateTimeLastComment, Comments) FROM Mods"; CommentCountDataSource.UpdateCommand = "UPDATE Mods SET (DateTimeLastComment=@DateTimeLastComment, Comments=@Comments) WHERE ModID=@ModID"; //How do i get the Where to use the query string info? CommentCountDataSource.UpdateParameters.Add("DateTimeLastComment", DateTime.Now.ToString()); CommentCountDataSource.UpdateParameters.Add("Comments", "10"); //"10" is just a value to test I'll change this to add "1" once I figure how. CommentCountDataSource.Update();} Sorry if I'm using the wrong lingo but as I say I'm new. If my code is a mile off then please can you send me in the right direction of some code that works.Thanks in advance if anyone can help me. Cheers,Alan

I am trying to update a SQL Server DB via my ASP.NET application with the following SqlCommand:
UPDATE StudentCourses
SET SC_Active = 0
WHERE (UT_ID IN (@UT_IDs)) AND (CO_ID = @CO_ID)
@UT_IDs in populated from a StringBuilder object with the following:
354,284,305,281,308,351,439,355,306,282
When I run the application to update the DB, I get the error:
System.FormatException: Input string was not in a correct format.
If I change @UT_IDs to:
354
if works.
Can anyone explain this behaviour?

I am a DBA who is moving in the direction of minor database design. I have gone through the steps to get my tables normalized, and I am ready to get them set up so they will update from table to table. How do I set this up? I know SQL does not cascade like Access, so how is this done? From what I have read (Robert Vieira's book) I should use triggers? Any help would be appreciated. Dallas

I have some code to hack in c#..
I have a database and when a form (C#) is loaded a copy of the table is made in a DataTable object. The form has a list box showing just the one column of info from the local DataTable.
On the form it is possible to change a record, delete a record and add a record. These are all done in the local table.
The question, how do i send these changes back to the database. Currently it deletes the lot and copies all the local table values in. How do only do the affected row, UPDATE, INSERT etc

Hey
I have an ASP application that uses a stored procedure and ADO.net to update a sql server data file. The problem is I know the code is working, I don't have any errors with the ADO, no exceptions are caught. I can use the same basic code to insert a record using a different procedure. It is the update procedure that does not carry through.
So, I know I have a connection, the procedure works using the query builder directly so the procedure works, but when I run the code, I get no errors and no update to the datafile. I am not even sure how to trouble shoot this since I don't have an error to look up.
C# Code:-------------
private void UpdateIssue()
{
DateTime date = new DateTime();
date = Convert.ToDateTime(this.txtDate.Text);
//edit record in HelpDeskIssuesTbl here.
SqlConnection con = new SqlConnection("Data Source...");
SqlCommand comUpdateTicket = new SqlCommand("sp_UpdateHelpDeskIssues", con);
comUpdateTicket.CommandType = CommandType.StoredProcedure;
comUpdateTicket.Parameters.Add("@IssueID", this.GridView1.SelectedIndex.ToString());
comUpdateTicket.Parameters.Add("@EmpID", this.ddlEmployee.SelectedValue.ToString());
comUpdateTicket.Parameters.Add("@Date", date.ToShortDateString());
comUpdateTicket.Parameters.Add("@StatusID", this.ddlStatus.SelectedValue.ToString());
try
{
con.Open();
comUpdateTicket.ExecuteNonQuery();
}
catch (Exception ex)
{
this.lblMessage.Text = "Data save error: " + ex.Message.ToString();
this.pnlMessage.Visible = true;
}
finally
{
con.Close();
}
}
----------------------------------------------------
dbo.sp_UpdateHelpDeskIssues
(
@IssueID int,
@EmpID int,
@Date datetime,
@StatusID int
)
AS
UPDATE HelpDeskIssuesTbl
SET EmployeeID = @EmpID, IssueDate = @Date, IssueStatusID = @StatusID
WHERE (IssueID = @IssueID)
RETURN
Like I said the Stored Procedure does work when I run it directly in Visual Studio. I have double checked all the params and they all match up unless I am missing something.
Please send help! Thanks.

Hi gurus,
My feeling with the SCD component is not that very solid. I have the feeling that the behavior of the insert/update strategy is not always correct an working.
I will describe two problems that i encounter.
1. My destination table contains records with the value ''. Cause i don't want '' ( 2 single quotes) in our DWH i update the view that is the source with a case statement that changes the '' to NULL. But when i run the packages the '' values are not update with the NULL values. When i delete the destination table and run the package, the records are inserted with the NULL value as expected. Anyone who has experienced this problem?
2. When i create a new table and run the package so the destination table gets filled with records the SCD will insert alle records (for example 100). When i start the run directly after the first run, all records are updated instead of doing nothing what it should do cause all records exists.
Anyone who can give me some feedback?
with regards, Arthur

Hi
I come from a Unix backgound and used Informix ISQL quite frequently.
I have a row that contains a compund field 'cust_and_date' and contains a value of C0003 32656
I want to write an update statement that will amend the C0003 to C00009 but leaves the 32656 as is.
I tried the following:-
update scheme.slitemm set substring(cust_and_date,1,8) = 'C00009'
This returned a syntax error
Any help gratefully received

I have this web store that I have been creating. When a customer goes to check out, he has to log in, then he is redirected to a page where he can view/add/or edit shipping and billing address. I have based all the sql statements on the profile username, adding records and retrieving them works just fine. When I go to change something in the info it uses an sql statement that updates based on "Where AccountUserName = @AccountUserName", I have @AccountUserName set to Profile("Username"). Keep in mind this works fine for adding new or bring up current records. I even put in code in the updated event for the sql data source to post a msgbox telling me how many rows were affected, it says 1 even though I dont see any change in the data. What am I doing wrong here, it's driving me nuts, its just a very simple update.

Hi
I'm new to all of this. I have a database that holds customer
information (fictitious) and i can select that data and display it in a
set of textboxes. I also have an SQL command "UPDATE" that is designed
to update the text field that i want to edit. However the problem i'm
having is that it'll let me write the info in the textbox but as soon
as i click my update button it just flashses and goes back to what it
says before
e.g. FIRST NAME: LEE i enter TOM and then it reverts it back to LEE
This is my SQL UPDATE command statement:
UPDATE CustomerDetails SET [First Name] = @firstnameTextBox, [Last
Name] = @lastnameTextBox, [Address line 1] = @addressTextBox, Town =
@townTextBox, Postcode = '@postcodeTextBox', [Tel Number] = '@telephoneTextBox' 1 1

Hi,I am currently updating a column in my database table with the value typed into a text box. But it is updating with the new value, rather than taking away the value typed in from the present value of the column. 1. How would i subtract the value typed in away from the current column value?2. I guess I need to check the column value is above 0 before updating, then rebind the control to show new values after the update has happened, incase two people are using it at once. How would this be achived? Thanks for any help!!Jon P.S.My code is:private bool ExecuteUpdate(int quantity){ SqlConnection con = new SqlConnection(); con.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True"; con.Open(); SqlCommand command = new SqlCommand(); command.Connection = con; TextBox TextBox1 = (TextBox)FormView1.FindControl("TextBox1"); Label labname = (Label)FormView1.FindControl("Label3"); Label labid = (Label)FormView1.FindControl("Label13"); command.CommandText = "UPDATE Items SET Quantityavailable = @qty WHERE productID=@productID"; command.Parameters.Add("@qty", TextBox1.Text); command.Parameters.Add("@productID", labid.Text); command.ExecuteNonQuery(); con.Close(); return true;} private bool ExecuteInsert(String quantity) { SqlConnection con = new SqlConnection(); con.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True"; con.Open(); SqlCommand command = new SqlCommand(); command.Connection = con; TextBox TextBox1 = (TextBox)FormView1.FindControl("TextBox1"); Label labname = (Label)FormView1.FindControl("Label3"); Label labid = (Label)FormView1.FindControl("Label13"); command.CommandText = "INSERT INTO Transactions (Usersname)VALUES (@User)"+ "INSERT INTO Transactions (Itemid)VALUES (@productID)"+ "INSERT INTO Transactions (itemname)VALUES (@Itemsname)"+ "INSERT INTO Transactions (Date)VALUES (+DateTime.Now.ToString() +)"+ "INSERT INTO Transactions (Qty)VALUES (@qty)"+ command.Parameters.Add("@User", System.Web.HttpContext.Current.User.Identity.Name); command.Parameters.Add("@Itemsname", labname.Text); command.Parameters.Add("@productID", labid.Text); command.Parameters.Add("@qty", TextBox1.Text); command.ExecuteNonQuery(); con.Close(); return true; }protected void Button2_Click(object sender, EventArgs e){ TextBox TextBox1 = FormView1.FindControl("TextBox1") as TextBox; ExecuteUpdate(Int32.Parse(TextBox1.Text) );}protected void Button2_Command(object sender, CommandEventArgs e) { if (e.CommandName == "Update") { SqlDataSource1.Insert(); } }}

Hello
How do u update the datafield of a row using buttonClick in vb? I have a details view whereby it will display the username and timeleft once log in. currently the datafield, timeleft on one user in the database is null. I'm using sqldatasource.
Once log in, it will direct to this page where the user enters a code on the textbox and click the enter button. This will cause an update on the user's timeleft. But the code must not be entered to the database.
For eg. If code = 1111 then 'update timeleft = 60 The timeleft is in minutes. 60 will be stored as double in the user's row in the database. How do i do this?
Please help asap. Thanks! :)

When I change the dates and submit it's not updating in the database instead I'm getting the two dates in pageload. What am I doing wrong?Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

DueDateTxt.Text = DateAdd(DateInterval.Day, 28, Today())

Hey guys, I periodically have to update maybe 300 records of the same column.. However, I've been udpating each record one by one.
Is there a way I can do something the following.ID Name1 john2 chris3 adam4 ben5 steveupdate table1 set name = name where id = ? but have it run through an entire set of these? Is there any way of automating that rather than having to update it manually? Do i need another table with just the id numbers and the column I want to change? or do i need a txt file?

building some kind of ecommerce site.
I want to allow the user to modify the image that he has stored for a product.
The image is stored in a directory, in the table GAMME I only have the image name.
When the user selects a new Image, I first delete the old image in the directory, then save the new image, but what I can't do is to update the table with the new image name, when I write sqldatasource1.update() I have an error "the dictionnary passed with old values is empty"(translated from frengh).
the update statement in sqldatasource1 is: " UPDATE Gamme SET imagename = @imagename, imagesize = @imagesize WHERE (product_ID = @original_product_ID)"
on events sqldatasource1.updating I have written:
e.Command.Parameters("@imagename").Value = (FileUpload1.FileName).ToString()
e.Command.Parameters("@taillevignette").Value = FileUpload1.PostedFile.ContentLength
e.Command.Parameters("@original_product_ID").Value = Session("Product_ID").ToString
this is not written but the session("product_ID") is the good value
the problem must come from the last lign, but I don't Understand the problem and how to solve it.
