I've been having a problem adding a record to an Access database using datasets and da.update etc. I'm trying to create a simple program that displays the records of a database table in a series of text boxes. I've managed to get my next and previous buttons working correctly and my update button works correctly too. The problem occurs when I try to add a new record. I keep getting a "Syntax error in INSERT INTO statement" whenever I click my add button.

View 1 RepliesHow to update a record database table from unbound datagridview using vb.net
View 7 RepliesI have a collection of objects (classes I created), and each one ties to a record in a database. I want an easy way to update the information, so I thought about declaring a record in the class, that would tie to the record on the database. However, I'm having a problem updating it now.
1) Can I declare a global variable for the data context, and leave it open the entire time the program is running? This would solve my problem, but I don't know if I can do that.
2) If not, besides coming up with a complicated class to do this, is there an easier way? Here is an example of what I am trying to do:
VB.NET
Public C as Record
Public Sub GetValue()
Dim SQL As New DBDataContext
Dim X = From T in SQL.Records Select T

It stays on the ra = OracleCommand.ExecuteNonQuery() continuously until i get the error The CLR has been unable to transition from COM context 0x3327fa8 to COM context 0x3328118 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.What could i do in order to get this working within VB.net since it works just fine in TOAD when running that same query?

I am creating a very simple Voting System, that will be use on electing new set of officer in a teacher cooperative...
So I have to create two separate program, a Server Program that will manage all the information in the election and a Client Program where voters will vote their selected candidate...

The form it is on is frmMidwest.vb, the database is MarchMadnessDB, with the table being tblMidwest and the column being Username. I am trying to get it so when the user loads frmMidwest.vb it will then check the database to see if the user has entered their picks and if they have it will load their picks back into frmMidwest.vb if the database cannot find their user then it needs to add a record to the database and allow the user to enter their picks. I have already established this with
TblMidwestBindingSource.AddNew()
But if the user exists I do not want them to be able to enter another record. The primary key in the database is the username.
Is there a direct way of generating a class from a record in the database?I use a program to edit records and would like to use a class that has the record fields as member for saving the last values entered while adding new records and the initial values of the fields for editing so that if i press ESC the control while editing the value returns to the original.I tried to use dim r as datarow but i get the error that there is no object
and if i declare dim r as new datarow i get the error that new is not implemented.Do I have to write the class definition explicitly?
I have the following code in a VB .NET application. I am trying to update columns in an Oracle table with data with SQL data. When I run the application, I get (ORA-00933: SQL command not properly ended) for the 'or_cmd_3.ExecuteNonQuery()' line.
If I strip out the code and run it in TOAD or SQL Developer, replacing the temp varialve with some bogus data it updates fine. What am I missing?

I am using oracle database and i already created a connection and retrieved data from my oracle DB to Datagridview using oledb commands,now my major challenge which has gotten me sick is to update any changes made in the datagridview to the oracle database. I tried using sqlcommandbuilder but failed. This code is what i used to retrieved the data from oracle and place it into the datagridview.
These are my declarations i made at the beginning of the form:
Private myDA As OleDbDataAdapter
Private myDataSet As DataSet
These are the codes inside the search button to load the retrieved data from oracle into the datagridview
Public con As OleDbConnection = New OleDbConnection("Provider=MSDAORA.1;User ID=SYSTEM; Password=simon; database=project")

How will I transfer deleted record into another table instead of deleting it permanently? I think it is what we call "history"..somehow..For example I have 2 tables. 1 is Original_Record the other is Deleted_Record. If I deleted one record in Original_Record, the deleted record will be transfered into Deleted_Record table.

View 1 RepliesThe system should not insert selected records from my datagridviewcheckboxcolumn if it's already existed in the database.It's like when you're registering online. If you're username/email address already registered,it would inform you that youre username/email is already registered and the site would ask you to change your username/email to new ones.The difference in my system is that i have 2 datagridviewcheckbox columns not just textboxes . Parent and Child in the datagridview. What i want to happen is that once the Code has been registered as Parent it cant be registered again as Child anymore.

I have the following simple Sub to write a dataset back to an Oracle database
[code..]
Checking the logs today I noticed that for some executions I got an ORA-0001 (constraint violation) error. It seems that one of the fields in the oracle table being updated is marked as unique and my dataset contains one or more records that have the same value in that field.
How is this error handled? Does it just not add the violating records? Does it hit the invalid record and quit? Does it rollback?
