DB/Reporting :: Query On Related Tables?
Nov 15, 2008I have a simple "two-tables" database (SQL EXpress) and a very simple application (VB 2008 Express). The two tables are customer and order and their structures are:
customer(IDcustomer, LastName, FirstName) IDcustomer=primary key orders(IDord, Number, Description, IDcust)
IDord=primary key the tables are related (IDcustomer-->ID cust)
In VB2008 environment I create a dataset, by means of Data Source Configuration Wizard, which encompass both customer and order tables (xsd file). By opening xsd file I set the relationship in the following manner:
"Both relation and foreign key constraint"
Update Rule = Cascade
Delete Rule = Cascade
In my form I show customer table in detail-mode and orders table in datagridview-mode. Two Fill method are created in the Load event and they work correctly.In "CustomerTableAdapter" I create, with QueryBuilder, a search query (say LastName query) and I write the following code:
Private Sub frmSearch_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CustomerTableAdapter.FillByLastName(Me.CustomerOrdersDataSet.custom er, "D") 'All Lastnames with first letter = D

View 1 RepliesSaving Related Tables And Querying Them?
Nov 9, 2009I 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

View 6 RepliesRelated Tables Data Entry Form
Oct 19, 2011I have a Microsoft Access database that has one-to-many relationships. When I created the tables for the database, I did not enter any data into any records, as that will be done by the application user. My problems is when data is entered into the parent and child tables, the parent table data is the only one that gets saved when clicking the save button on the binding navigator.If I have the parent and child tables data entered the same way a user would prior to connecting the data source and add EndEdit() to the child table BindingSource in the BindingNavigator click event, everything works exactly the way I want it to.This application is a data entry form, so it wouldn't make sense to have to have data entered in tables prior to adding the data source to my project. What is the best way to create a data entry form with one-to-many relationships? [code]

Therefore, StudentID is the primary key in the former whereas it is a foreign key in the latter.Now I've tried each of the following codes but each of the first two gives an error message "Incorrect syntax near 'a'" and in the case of the third one DbTransaction as in "Dim trans As DbTransaction" is also not a valid type.

Winforms - Bind A ComboBox To Related Tables?
May 14, 2012I am developing a Windows Form Application against a SQL Server relational database. An example of the database schema is:
TableA
------------------
PK A_ID uniqueidentifier
A_NAME varchar(254)
[code]....
In the form I have a ComboBox (cboA_ID) to select the TableA record (DataSource = TableA, DisplayMember = A_NAME, ValueMember = A_ID) and a TabControl where controls on each tab are bound to fields in either TableB or TableC.My question is, is it possible to bind cboA_ID to TableB.A_ID and TableC.A_ID?This is my first database application so if there is a better way to do this I'm all ears. I have set everything up using the wizards in Visual Studio 2010, so I'm still not 100% familiar with what all the various TableAdapters and DataSets do.
