"Deleting rows from multiple tables in SQL 2005". I need to delete all the rows in the multiple rows where it's the same UserId. My Delete command below:
Delete From tableA
From tableA INNER JOIN
tableB ON tableA.UserId = tableB.UserId INNER JOIN
tableC ON tableA.UserId = tableC.UserId INNER JOIN
tableD ON tableA.UserId = tableD.UserId
Where (tableA.UserId = @UserId) AND (tableB.UserId = @UserId) AND (tableC.UserId = @UserId) AND (tableD.UserId = @UserId)
What is happening from the above query is only the rows from tableA is getting deleted.
I have a form with multiple tables. when I add rors into the tables I Use code like this:
Dim n As Integer = 0 For Each copyRows1 In copyRows Dim newOrdreRow As DataRow = Kalkyle1DataSet.Tables("Ordre").NewRow() Dim Ordredato As String = Kalkyle1DataSet.Tables("Ordre").Rows(n).Item("Ordedato")
where I add new rows also addin a OrdreID as Foreign Key.
How do I Delete all records in the tabel with the foreign key = * ?
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 looking for some advice on this since I know nothing about database projects or sql, except that they have data stored in tables and rows. I have a sql back up text file from my forum, and I would like to bring that in to a VB.net sql db project. What do I need to do, to accomplish this?
I started out with just one table called products but I had problems with doing an update; it said sql to complex which was because the product table had nearly 100 columns in. The products table consists of header information like product quality, colour etc. Then there are 3 blocks of columns which mainly consist of a size as being the column name and a quantity as being the value. I have put these in three seperate tables to get around the SQL update problem. My problem is what is the best way to code this. The tables link to the header table using an autonumber primary key.
I've found alot of examples for add/edit/delete a single table. In VB6 ADO you could load multiple tables into a recordset using the join command. Then manipulate or modify the data.
I've found how to retreive multiple tables like,
Da = New OleDb.OleDbDataAdapter("Select groups.groupid,groups.userid,lots.groupid,lots.lotid from groups inner join lots on groups.groupid=lots.groupid order by groups.groupid asc", DB) But the only way I have found to update is to use seperate Update commands for each table.
i want to save into my sql server 2000 database multiples rows of a datagridview. i tryed something that first was working good, but i did a code change removing a column so now i'm trying to save again but i can't do it. It's shows me a message error like this: THERE ARE FEWER COLUMNS IN THE INSERT STATEMENT THAN VALUES ESPECIFIED IN THE VALUES CLAUSE. I rewrite the code, delete and add a new table and my code has the same values in the insert than my values clause. I don't know what else i have to do.
Here is my code
Private Sub cmdAceptar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAceptar.Click Try
have a datagridview containing 2 tables left joined, so that:table1 LEFT JOIN table 2 ON table1.id=table2.idI get an error whenever I try to edit my datagridview."invalidOperationException was unhandled by the user codeDynamic SQL generation is not supported against multiple base tables."The error points to this line:

I have a table in where I am trying to delete all the rows except for the first. I did manage to come up with the code following:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim dtRemoveRows As DataTable =
[Code]....
In review, this code sort of holds the first row and clears the remaining rows. However, when I exit and reopen the program the rows return. So in other words, I want the rows to get permently deleted. I have searched and cannot find a solution to permenly delete all rows without deleting the first row.
I have the following xml file output below where Deleteme="true" is written when the user clicks on the row's checkbox. I was thinking that once the data is flagged this way I could read the data back in, somehow delete each row specified as above, and then save the data back out.

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.
This is such a basic question, I'm almost embarassed to ask it. How do I loop through seleted rows in a DataGridView and remove the rows?I've tried this, but it doesn't work. After one row is removed, the index is all screwed up.
So I've created a gridview with checkboxes so the user can check as many fields as they want and delete them with the click of a button. It works except that it deletes all selected rows except one, the row with the lowest number. I can't firgure out what logic error is causing this.
Here's the code for the delete button procedure:
Protected Sub btnDelete_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDelete.Click Dim count As Integer = 0
I bring data in from an access database using a sql query and then assign the data to a datagrid view. When i try to delete data from the table, it is removed from the datagrid, but the change is not showing up in the actual table.As a second question, is there a way to tag the specific row and send that back to the actual database for deletion? The way i have it set now, i think would delete all instances where digit, day, and office match, instead of just the selected record.
I have a form with a listbox bound to a tableadapter. Users can select from a combox, that has a list of users in it, then click "Add" to add it to the listbox and remove to remove it. This part works fine. The problem comes when updating the database:
How would I delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If I dont delete the successful rows then I will have multiple inserts of the same dataRow and we dont want that! And if I don't move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic I am trying to perform at the bottom of my code, right after I insert into the database.
Here is my code. Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click 'Function declarations 'Object declarations Dim localOutputServer As SQLServer = Nothing 'Variable declarations (Form) [Code] .....
With a DataGridView bound to a bindingsource, which is filled by da.fill(ds) . How do I go about deleting selected rows when the UserDeletingRow event is fired? I've used the following code in the event:
Dim dsEmplTran As New DataSet daEmplTran.Fill(dsEmplTran) dsEmplTran.Tables(0).Rows(dgvEmplTran.SelectedRows(0).Index).Delete() Dim cb As New SqlCommandBuilder(daEmplTran)
i've been all over the internet to solve this problem, but i've found no solution to my problem.my concept is this.Based on selected value within a combo box, the datagridview will populate with values from the database.
i am working on my first database program. i believe that I am almost finished, except that i have a remove button like i would like to remove just a single selected row both from the datagridview and the actual database. this is just in case any information is entered wrong, and also to delete all the entries i put in just for testing purposes. the only problem im having is in updating the database after removing the row from the datagridview

I am trying to delete rows of an .sdf file using the Database Explorer utility of Visual Basic. When doing so, I get the following error message:No rows were deleted.
A problem occurred attempting to delete row 1.
Error Source: Microsoft.VisualStudio.DataTools. Error Message: The row value(s) updated or deleted either do not make the row unique or they alter multiple rows(48 rows). Correct the errors and attempt to delete the row again or press ESC to cancel the change(s). It is correct that the data in the rows are not unique (and not supposed to be; there is no "error" to correct), but why should this prevent deleting them?
I have an Access table in which I connect through ODBC commands. I want to delete the 50% of data rows from it. Can anyone knows a string to write for doing that? ALARMLOG is my table. In MS SQL I tryed succesfully the following command :
I pass it a valid dataset that has the department name and the Department id as a number..20, 40, 30..... I want to get the department number.. I pass it HR(which is in the ds.table) but I am getting an error on the rows.find() "Input string was not in a correct format" it is a string.. what else could i be doing wrong here...
Public Function GetDeptID(ByRef ds As DataSet, ByVal strDepartment As String) As Integer 'Dim dr As DataRow ' Check to see if date is already in the table
I have a small project i am doing for work to compare our website catalogue to our actual inventory in our financial software. To do this, i have exported the online catalogue as a delimited text file using "^" as the delimiter. I then want to go into our Accpac data a find out if all the items are still active, the current price and the stock on hand.
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 have been trying my hand at this for some days now and just cant get anything to work. Below is the code im currently using to delete a row from a database table, the problem when trying to build the project line 5 is giving this error about the value con" Value of type String cannot be converted to 'System.Data.OleDb.OleDbConnection' "
Dim con As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=Customers.mdb" Dim cnn As New OleDb.OleDbConnection(con) cnn.Open()

I have also tried using this code below, but to no success. Im basically just looking for something rock soild that i can use to accomplish this task. Been stuck on this for quite a while now.
