Querying & Updating Multiple Tables With VB 2010?
Mar 15, 2012
I've been searching all day about this and can't find a solution..I'm fairly new to VB and SQL Queries, so I apologize if I sound a little daft.Basically I'm working on a project in VB 2010 where a user can add new teams, players, also create matches between teams and record the score. I have done nearly all forms, but now I need to show data from 2 tables on one form and the method I used for 1 table doesn't work.I have 4 tables:team, player, match & matchdata and they are linked like this:

Using; - vb2008 Express, data on ACCESS 2003, objective; - to update a separate table not on the original query.From what i have gathered i need to add a second table adapter to make the changes to a related field in another table. Since i already have the 1st table adapter the second does not appear as easy as the second (dragn the data set over).
So i suppose i need to create the second table adapters programmatically? [URL]..I see that because they are not nested they need to each be declared.. right? If so that is where my issue lies. I'm having a problem with how to declare them both now that there must be two.

After making the changes or adding a record I use invoke childmethod from my toolbar to call these subs. The first table updates and adds, but the second does not. I have set all of my textboxes databindings and double checked them. I get no error, but it does not update the second table. What am I doing wrong?
Public Sub AddRecord()
'Clear out the input data fields on a new Add.
ClearInputFields()

I have one DataSet and two forms, Customers and Efficiency. When I make changes to the Customers table (Delete a Customer for instance) It does not reflect the changes on the Efficiency table. The default form is Efficiency and I'm calling the Customers form from within the Efficiency form. I make the change in the Customer form, I then close the Customer form and call the Efficiency form back. The data is not updated on the Efficiency side until I close the application and re-open it. what code I need and where to inject this code?

I am having a problem saving related tables and querying them. I have both data binding sources on the form and I have both being added, end edit, and both being saved. When I "view all" and click on the related table "crimes" they're not showing with the Inmate that committed them. I have gotten it to do this with a code similar to that below and I am wondering what I'm doing wrong so that the datagridview for crimes will display the correct crimes for the correct inmate. The primary key for inmates is DOC# and the Primary Key for Crimes is "Entry ID"
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click

I am trying to create a stock scanner which allows users to filter stocks based on multiple criteria that they select. Like the following example with 2 criteria:
Criteria 1 Filtered Result: StockA, StockB, StockC, StockD
Criteria 2 Filtered Result: Stock B, Stock C, StockE, StockF
SCANNER RESULT: Stock B, StockC (ideally this result would be displayed in a GridView)

I'm using this function to return a value from multiple databases across three SQL instances (On the same server). I'm looping though a DataGridView that lists all the databases on one of the three SQL instances.Is there a faster way of doing this? It's quite slow using this method.
Function DatabaseStatus(ByVal SQLServer As String, ByVal Database As String)
Dim myConn As New SqlConnection("Server=" & SQLServer & ";User Id=USER;Password=PASSWORD;Database=" & Database & ";")

I have looked at the answers in the forum and some seem dated. I an an old vb2 person and need to move up. I understand sql very well and use complex queries. First test project and trying to add multiple tables to a data grid (Only Form in project).I used the Data wizard to add the Access data base and worked by way through to near the end. The query works in the wizard and returns the correct rows. The error message is "The solution returned by the new query differs from the base query."
During the creation process I selected all the tables. Reading some of the old anwsers I get the inpression that VB 2010 does not handle multiple tables in a datagrid (forum items go back to version 2008).

I have multiple tables that I need to pull and display data from. I have created a new query in the TableAdapter of one table to pull data from related tables based on a parameter. In the Query Designer I can run my query and see all of the columns requested in my SELECT statement, however when I bind this table to a DataGridView and call the new query, it only returns the original columns from Table1.How do I see all of the columns I selected in my query?

I'm writing a time entry program to record when an employee checks in and when they check out.I'm struggling on the part where I need to calculate a time span (time out / time in). I am selecting the In Time, Out Time, and Total columns.I want it to take the Out Time subtract it from the In Time and place that value in the Total column.I have so far and have tried several variations of different updates but have had no luck.[code]I keep getting a syntax error in the UPDATE statment.I'm not very fluent with OleDB yet and I'm not sure if I'm doing the update correctly.I have no problem with OleDB and single UPDATES or single field updates but when I am updating multiple rows with different values.

I have a web application and on page is an update page to update some profile information. Below is the code I am using to update the table. But I think it is wrong. Does anything stick out? The connection string works cause it is used to read the database to get the profile information, I just removed it due to it containing password/login info for the db.player is the class of properties that contains player information and ds is the dataset, but I would like to update the database itself online.

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 have three tables Tasks, Notes & CallTypes Each item in Tasks and Notes has a relationship to CallTypes and my form edits work fine. However: Notes only belong to tasks, and when i update the note record we will need to change the CallType for the Task as well as for the Note and they could both be different.
I have the Notes working fine, but i cannot update the tasks. I have created a databindng on to a form from the datasources window. All the notes fields are ok and are working I then add the calltype field from the tasks, draged from the data sources window (i dont want all of the tasks fields, just the calltype).
The code does not through up errors, but when i save the form it only updates the notes and not the tasks.
