VS 2008 Insert Autonumber In Foreign Table
Aug 17, 2011
I want to insert data into my tables. Table 1 (Recipes1) has a primary key (Autonumber) Table 2 (Ingredients) has a Foreign key with the same name as the primary key in Table2 ("RecipeNumber) this is a normal number field. The problem is that when i update the tables, it does not even make it past table1 , which should be ok.

For simplicity, I have a database with two tables, as follows:
/---------------------------------------
| Table Name: GRADES |
|---------------+---------+-------------|
| Column | Type | Comments |
|---------------|---------|-------------|
[code]....
On my form, I'm trying to display information about a grade. I'm using a DataSet with BindingSources and TableAdapters. Using the tip from here, I'm populating the selected grade's ID, HazardType_ID and Code. Unfortunately, I want to display the the HazardType, and not the foreign key index. I've accomplished this with the following
' get the data
Dim data As ProjectDataSet.GradesRow = DirectCast(GradesBindingSource.Current, DataRowView).Row
' fill in form fields
[code]....
Note, I'm using VB Express 2008 (.NET 3.5) and connecting to a MS Access database.

I use the following code to insert some data into a DB:
strSQL = "INSERT INTO tblItems(itmTitle, itmCode, itmImage)"
strSQL += " VALUES('" + txtItemTitle.Value.Trim + "','" + txtItemCode.Value.Trim + "','" + c + "');"
[Code]...
With the DB table having an additional field called: itmID which is an Autonumber field so I dont need to add any data to this field.
But after the above SQL code has been executed I want to get the itmID number assigned to the new record - but I am not sure how to do this.
Im thinkin maybe using SELECT function but with WHERE filtering by the details I have just added but dont know if there is a simpler way.

The INSERT statement conflicted with the FOREING KEY constraint "FK_tblBook_tblCategory". The conflict occurred in database "CIEDC", table "dbo.tblCategory", column 'CatID'. The statement has been terminated.
Was that because of my database's relationships?

I am new to VB.net and have created a simple master detail windows form. I created a two table data set and then dropped the master table on the form as a continues form or a detail form with several text boxes to enter data. The child form is a data grid and was simple drag and drop from the data-set. All of this was done with drag and drop and I have added nor changed any code.test data that I have added directly to the database shows up with the proper parent child relationships on the form. I can also enter new records into the database using the parent only portion of my form. I can also update a child record.When I attempt to enter a complete record with data in both the parent form and the child data grid I get this error.
The INSERT statement conflicted with the FOREIGN KEY constraint FK_tblComplainant_tblUseOfForce. The conflict occurred in database "C:\SQLFILES\CCTS_2.MDF", table "dbo.tblUseOfForce", column 'UOFID'. The statement has

Is there a simple way that I can replace a foreign key in a datatable, with a corresponding value from the table that the key is referring to, without having to create a new table or use tableadapter? Ive got a table that has a foreign key to a child table, and I need to get a column from that table to fill a dataview?

I have an application where I need to be able to search for the workers related to a company from a contacts list. I am able to do this by entering the company number but I am unsure how I can set the query to allow to search for the information in the other table.
[Code]...
SELECT RecordNo, CompanyID, AccntRep, CustNumber, Person, SubjectID, StatusID FROM dbo.Contact
WHERE CompanyID = @companyNo I think that I need to create a join in the SQL statement to the company table but am unsure how to go about this and I would be grateful if someone would give me a point in the right direction so that i can search for the company name instead of the companyID.

Dim table As DataTable = New DataTable(tableName)
Using connection As SqlConnection = New SqlConnection(GetConnectionString)

How can I get the ForeignKey Constraints?

I have an Access database where I want to store the contacts in a company: In this database I have a table named "users" where I keep the users which will have access to the database. In the main table, named "contacts", two of my fields "insert_user" and "contact_user" refer to the user who entered the contact information and the user who actually made the contact. The way I am thinking it, I will have to set both of the fields as foreign keys to the same table/field, namely "users"/"username".
So:
I set two foreign key constrains in two different fields ("insert_user", "contact_user"), which refer to the same table/field ("users"/"username") in an
Access database, using VB.Net OleDB (See the SQL Statement below)
ALTER TABLE contacts ADD CONSTRAINT insert_user_foreignkey FOREIGN KEY (insert_user) REFERENCES users (username)
ALTER TABLE contacts ADD CONSTRAINT contact_user_foreignkey FOREIGN KEY (contact_user) REFERENCES users (username)
I open the database with MS-Access. I see that all the tables are fine (as they should be).
However when I click on relationships at Access I get all my tables plus a table named users_1 connected to "contacts"/"contact_user" (the table users is only connected to "contacts"/"insert_user")
It is very strange that in the Table View of Access I don't see this table, but only in the Relationships View.
Questions
Is my thinking right (to set 2 foreign keys, that refer to the same table/field)? What is this table "users_1"? Will my database work or am I doing something wrong?

I have 2 Tables , OrderDetails and Requests In my LINQ to SQL dbml file. OrderDetailsID is a foreign key in Requests Table.
I want to write the query to get the sum of UnitCost from OrderDetails based on OrderId. And If there is a row in Requests Table for each OrderDetailsID, and the Requests.Last.RequestType="Refund" I want to reduce the total refund amount from the main sum otherwise If there is no row based on OrderDetailsID, add to sum.
Here is the way I implement that. I am looking to prevent using "For each".
iRefund = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1.UnitCost).Sum

I'm currently trying to create a function to parse error messages to make them more helpful for the end user. Currently I'm working with SQLServer and VB.NET.
Right now I'm raising error 547 which looks like this:
DELETE statement conflicted with COLUMN REFERENCE
constraint Constraint Name. The conflict occurred
in database 'Database Name', table 'Table Name',
[Code].....
I'm able to pull every piece of information I need from the error message except the name of the parentTable. I've already determined that the SqlException doesn't store the statement that caused the exception, and as far as I can tell it doesn't store information about the name of the parent table, only the table that is trying to reference it.
Is there an easy way to get the name of the parentTable?

I am using a number of tables on my application and two of which have a foreign key constraint I have set between them. When I change the account number on the main table via a combo box all of the relevant information for that table on the form is updated accordingly. However, the child table which has a foreign key reference to the Account Number of the main table is not updated when the acocunt number is changed. I have set the update to cascade in the references but still am having issues.

I would like to have a pop up messagebox that asks users for confirmation before deleting a record in datagridview and if the record is a foreign key to another table, another messagebox will appear and warns users saying" before you can delete this record, make sure you remove all the related records" I have tried but I don't know how to complete it.

I have created a users database in access and included that database in the bin directory of my project. I have then created a connection to that database using the wizard in 2k8 express.What i need to be able to do is to insert usernames into the users table in the database. I am at a loss of where to start with this problem. Do i need to create a recordset or not? If so how do i write an sql query in VB2K8 to insert data into that recordset and then update the underlying database?

I do this in Oracle databases just in a snap, but now I have to do it in VB using ADODB and I don't know how to do it.
I have two Access 2007 tables. Table A contains: Col1 (text), Col2 (text), Col3(date), Col4(amount), Col5(text)
Table B contains Col1(date), Col2(amount) What I need to do is to insert into table B the records of table A (col4 summed) grouped by date of table A. The date is a variable contained in a text box so it cannot be hardcoded into the SQL statement.
