Table Will Not Update?
Jun 2, 2009
I am working on a timekeeping application using Visual Basic 2008 Express and Access 2000.The database has two identical tables, each with 50 identical fields. Only the table names are different as are the input control names on the Windows form. The queries are also identical except for the query name and the reference to the table name in the "INSERT INTO" statement.
The sub procedure in Visual Basic for Week 1 works perfectly and inserts the record. The sub procedure for Week 2 runs through all commands and parameters but doesn't update the table.I have looked at every line of code, every parameter and every entry in the query and find nothing wrong. I run the query from within Access and it works fine.
Heres where I find an inconsistency that baffles me.the last lines of code in both sub procedures are:
objData.OpenConnection()
objData.Command.ExecuteNonQuery()
intRowsAffected = objData.Command.ExecuteNonQuery
[code]....
I set breakpoints at each line an the procedure that works stops at each of the six lines of code, the procedure that doesn't work gets to the 3rd line(in italics) and then exits the procedure with no error message and no indication as to why the record was not saved.

I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!

An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.
dr = dbDset.Tables(0).Rows(CurIndex)
dr.Delete()
dbAdp.Update(dbDset.Tables("addresses"))

How can I update local dataset with mysql database without making duplicates. Assuming I set some column in mysql as primary key, which has unique string.
adapter.fill will just add duplicates, but adapter.clear before that is not an option.
So I want to update if the key column is the same with mysql data and if there is option for ignore adding new row.

I need to Update Access Database Table with Data from a Different Table. Not all the rows of original Table to be Updated will be affected. How do you loop through the 2 Tables to do the required Update.
The Table to be updated is called "RecordList" and Table with new Data is called "RecListReport".Every attempt I've made won't work. I tried to Use 2 Datagridviews but couldn't get it to work right.

I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.

in my every form i use update button to update values in a raw,
Now my query is that:- for doing so right now i have two option
1) UPDATE Table1 SET Column1 = Value1, Column2 = Value2 WHERE Some_Column = Some_Value but in this if i have many colom it will be a long process as in some table i have more than 50 coloms.
so i found a second option which is, first delete the row and then again insert the values but in this case it changes its row no which in some case not good for my project.
so i want to know is there any way to update * . or is there any short way to update similar to delete and insert.

I can pull 3 tables data into my program and read from all of them, I can update all 3 datasets but when it comes to updating the actual database i can only send the updates from the last dataset.
Imports System.Data
Dim con As New OleDb.OleDbConnection
Dim ds As New DataSet
Dim da As OleDb.OleDbDataAdapter
Dim sql As String
Public Sub OpenAllTables()
[Code] .....
The above code is how I call the three tbls, the weird thing is that if I switch the order (savings with expenditure) then savings will be allowed to get updated and not expenditure.

I have an application in VB2008 and using SQL Server 2005 Express Edition. I found an error in a value that I had entered in the SQL Table and want to correct it. All I needed to do was to change a numerical value in one of the columns from 18.4 to 16.4. This table is used to fill a combobox drop down menu in the application. After I changed the number in the data row, I saved the change and ran the applocation in debug but the original number still appears in the drop down menu. If I exit Visual Studio and re-open it, the change still appears in the database table but does not appear in the combobox, when I run it in bebug.I have made changes like this many times in this application and this database table, As I recall, all I had to do was save the change and I have never had it fail to update the change in the data row.

I've created a Point of Sale program using Access and VB.net. I have an Inventory table from which items are sold. There is a quantity column and I want to be able to reduce the quantity for any item by the quantity that was sold in the point of sale front end. For example, there are 5 bracelets in inventory and 1 is sold. The quantity is typed into a textbox. The inventory quantity should now be 4 in Access. I don't know how to make this happen from the point of sale screen.
