Multiple Rows In Add Row - Error Says That The Row Allready Exists In The Table
Jun 22, 2010
Have a method who gets data from one table, put the data into variables before it it returned into the same table with changed ID etc. My problem is that it adds the first row without any problems, but when it is supposed to add row number 2 the error says tha the row allready exists in the table. and I can not understand why. I have put in a couple of messageboxes to se that the ID is changing and that the ordreID is correct and changing as they should and they do, but stll I get that errormessage.
My code looks like this:
Public Sub Ordreupdate()
Dim dtbl As New DataTable
Dim dt As New DataTable
dtbl = Kalkyle1DataSet.Tables("Ordre")
dt = dtbl.Clone
I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.
I'm trying to create an option to select a specific entry in a SQL table if multiples exists. The Sub listed below is for a textbox (MOTxt) and a button (GotMO) for checking an MO# to pull from SQL. Based on the number entered, will populate other text boxes on the page with that row's data. There are exceptions to this, where the MONumber will be entered more than once with different data associated with each entry. So, here's my situation. If we have a duplicate MONumber listed in the table, it will populate the textboxes with the first entry it finds for an update.I would like to create a dynamic dropdownlist (that displays only if multiples are found) displaying the 'Name' field entries for each MONumber found, then once the correct name is selected from that list, to then populate the textboxes with that selected datarow.Here's my code behind:
Protected Sub GotMONum_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles GotMO.Click Dim da As New SqlDataAdapter
How can I insert multiple rows from one table to another. I have query(SELECT which returns multiple rows)from table A and would like to insert all rows (as a result of query) into new tabel B.
in my database there is a table holds information about the customer. in my application, in a form user can input many customer ids. when they press the update button in the customer table, a single field should be updated for all the customer ids user entered. is there any way to do this. SQL server 2005 is my database. if you think the solution is sql bulk update, can please explain me how to do a bulk update.
I am trying to append multiple rows in a SQL Server.I have connected to the MS SQL Server and with a DataAdapter, I have downloaded the Table into a DataTable and displayed it in DataGridView.I now want to programatically enter multiple rows into the DataTable and later to update the SQL Table.
I am trying to build an application to do this generically.The problem I have is that the Table and DataTable has an 'ID' Field. In the SQL DB, i is an Auto-incrementing field.When the code loops through creating new rows and entering field values, how do I handle the ID Field that is the Primary Key?
I have the following function that returns only the 1st row of data and puts it in a nice table. My knowledge in this area is limited in that I don't know how to create the table to return multiple rows. Can you show me how to change this to return all rows, no matter how many there are? my sql select statement may return 0 rows or many rows.

I have a Windows application form. Directly on the form I have a lable ("Customer Names"), a ComboBox (pulling actually names from a database) , and a Buton to add a customer to the database if i choose. Additionally I have ControlTab(3 tabs) that has "fields" and its own Buttons to insert data into a different table. The first 2 tabs have textBoxes, which are completely functional, but the 3rd tab has a "DataGridView"
I have datagridview1 binded to data Table1 (with binding source) . This data table1 is in relation with his child data table2.When I insert new record to table1 I want to refresh datagridview1.
If I use table adapter fill method I get error.TableAdapter1.Fill(Me.DataSet1.Table1) ' error error: Cannot clear table Table1 because ForeignKeyConstraint FK_Table1Table2 enforces constraints and there are child rows in Table2.
I have Dataset ds filled up with values Until now I was displaying values in GridView. Now I want that all the rows should be columns and columns should be rows.I have 2 options: Either 1 I can directly convert grid to columns and display it, or 2 I can convert the GridView to html and then write loops to convert. I was trying the 2nd option but I cant figure out how I should do that.[code]With this code I am still getting same as GridView. Please help me for converting rows to columns and vice versa.
I am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.
I have a query that I have to run that requires me to get rows from a table based on the value of a field in another table (which I have gotten earlier). I currently have it done like this (simplified).
I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts
I am using MS-SQL and I am trying to write a query which fetches rows from the master table and related rows from the detail table. Now, the thing I want is that it must only fetch the first row from the master table and related field from the detail tables should be blank in that first row, now if there are related rows found in the detail tables, they must be shown in the separate rows. I have been trying using the following query but it is not giving the desired result.
I'm using the following code (System.Data.SQLite within VB.net)[code]...
I know the table exists because I can write to it via the command line through sqlite and through Autoit and can see it and edit it in the SQLite browser when I open the database. I don't understand why VB can't see it (I know it sees and opens the database file just fine).
I developed a package in vb6.0 backend as oracle 8.1.7, i instaled my package on nearly 50 client systems, every thing is fine except ,in some screens when iam saving the record it displays the message "Table or view does not exists", but this error is occuring only on thoes systems using other than Windows 2000 OS . What might be the problem
I dragged and dropped a label control on my web form. But then whe I go to my VB .net code behind file, if I try and set a property on that label control, I am getting a "Declaration Expected" error message for the label I created.Yet if I do try and explicitly declare my label control, the compiler tells me that the label control is already declared.[code]
I'm using ADO.Net to work with an Excel Document. Essentially, I'm looking up values in a table called "source" and creating a new table called "result" which will be populated with the results of my query.
I have a couple of questions.A) How can I check if a table exists and create a new one if it doesn't? B) Is a table the same as a sheet in Excel?[URL]...
I have a tenant details form that has a field called TenantID, I also have a Lease table that also has a TenantID field, what I want to do is click the lease button, check to see if the lease already exists, if it does open the lease form to that record. If not then open the lease form to a New record so the user can enter all the information for that lease.
I am trying to use the below code but am having a little trouble understanding how it all works. What needs to be declared, what doesnt
HTML Private Sub btnLease_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLease.Click Dim fm2 As New LeaseDetails
I have an 'invoices' table with a column for the invoice number.
When adding a new invoice, I would like to check if it already exists. If it exists, produce a MessageBox to the user that there's already a record with this number.
i am trying to search a table in an access database to see if the value of a text box exists in it. I have this so far:
Dim myConnection As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & Application.LocalUserAppDataPath & "\Database" & "\Student Aid Database.mdb") myConnection.Open()
I'm trying to check if a LINQ Entity exists in its table, but at design time I dont know what type that entity is. So I figure I'll just get the table, and try the Contains method on it. But I cant get the table in such a way that I can query it at design time.I've tried the GetTable method on the datacontext, but I dont know how to cast it to the appropriate type when using GetTable(Of). GetTable(Type) works, I just use Entity.GetType(), but then I don't know how to query the ITable thats returned.To try and cast the ITable to something useable, I created an interface(IWhatever) that could implement properties that are native to all of my entities I would encounter. [code]
I'm trying to query old Access database tables and compare them with SQL Server tables.They often don't have primary keys, or they have extra fields that had some purpose in the nineties, etc., or the new tables have new fields, etc.I need to find records - based on a set of fields specified at runtime - that are in one table but not another.So, I do this kind of query all the time in SQL, when I'm comparing data in different tables:
dim fields_i_care_about as string = "field1, field2, field3" 'This kind of thing gets set by a caller, can be any number of fields, depends on the 'table dim s as string= ""
[code]....
It tells me it can't convert a Boolean - Is there any way to do this without Linq expressions? They seem far more complex than what I'm trying to do here, and they take a lot of code, and also I can't seem to find examples of Expressions where we're comparing two fields in a subquery.Is there a simpler way? I know I could do the usual EXISTS query using JOIN or IN - in this case I don't need the query to be super fast or anything. And I don't need to use a DataTable or DataSet - I can put the data in some other kind of object.
I've got a table in an SQL server that often has large amounts of data imported into it via an automated process - the problem is that a lot of the data that gets imported is a duplicate of data that is already in there (for example if we have a customer in there called Mr Customer Ltd, a duplicate with a slightly different name could get imported, like Mr.Customer Ltd).
So I am using the Fuzzy Logic class that Wild Bill put in the CodeBank to find names that are similar and then highlight these items. The thing is that the target table that the imported data ends up in has several thousand rows and the table that contains the data to be imported often contains several thousand rows as well, so I'm trying to decide how to do this. Obviously reading both tables into memory is not an option as it will consume too much memory on the client PC that is running this app. So this is what I am doing at the moment:
1. Read the table that contains data to be imported into a DataTable in memory
2. Open a connection to the target table and use the SQLDataReader to start to loop through it
3. In this loop, for each row that the data reader reads I then loop through the entire set of rows in the DataTable and run this fuzzy logic method that compares the account name from the current row in the datatable loop to the account name in the row that the datareader is currently on.(there is also a Thread.Sleep(1) after each row is processed to prevent the process from eating up 100% of the CPU while it runs)
