I have two similar databases and i want to update a table of one database from the other, so insert new records, delete records that are not in the source and update different values.I use the dataadapter update method but it not recognize the primary key, so it only work when the destination table is empty. Otherwise i have an exception of duplicate primary key.The databases are sqlite but i tried with access too with the same error (different message due to different provider but the two times saying that cant insert because the primary key is duplicate).
My code is:
vb
Private Function updatetable()
connectdbsource()
connectdbdestination()

I populate a datagridview using a bindingsource and dataadapter. So I join 3 tables in the view to get the data i need.
so I have my view as a child table in my dataset. and a table called classes which is the parent table. So when I select a Class(class 1A for example), my datagridview displays the pupils in that class.
Now i need to add another relationship in the dataset. so when I select a day in a monthcalendar, I need to add 5 checkbox columns for each day to my datagridview. Should I add these 5 columns to my datatable? i'm not sure what the best way is.
Then for each day I tick I have to save to my pupil_job_day table. I will save the peoleid,their accountid and the date. please help me

I posted in the Database development forum, but no bites. I have field names in my Access table which have a number as the first character (i.e. "2x2"). Evidently, the DataAdapter doesn't like this. I'm able to view the data in a DataGridView, but I get an exception when I use DataAdapter.Update.
Can I modify my sql statement to make the command builder work or do I have rename the fields?
For example:
"SELECT [2x2] as twoBytwo..."
Changing the names of the fields would be a huge pain-in-the-arse!

Now I need to run different update statement etc to update each table. foe example I will update balance field in the accounts table using one query and another to update days present etc.
how should i do this? must i loop through each row in my datagridview?

This should be a fairly simple one. I am creating a dataset which will contain a description field which I would like to sort by. The reason I want to sort the dataadapter and not in my SQL is that I am already ordering by the results that have a particular value.My SQL looks like this:
SELECT pif_desc, pif_fund, psf_end, (CASE WHEN SUM(pmi_units) IS Null THEN 0 ELSE SUM(pmi_units) END) As fundunits
FROM tbl_mem INNER JOIN tbl_sfunds[code]....
I want to sort the datarows is ds.tables(0) by pif_desc but still have the rows with fundunits > 0 listed first. how I can achieve the correct ordering.

I have been researching all that is related to DataSources, DataReaders, DataAdapters, etc, with an Access 2010 DB bound to a DataGridView.
Everything is fine, just one line fails and is driving me nuts Here is the code:
[Code]...
The line that fails, actually updates my database, but somehow, the update is not performed on the line that belongs to the first row of the grid. What is more, if I change the value manually, the same update method works fine. What is going on here?

I'm trying to create a form that uses controls that are bound at runtime. All the data objects are declared at the form level. The Select statement includes the two fields that make up the PK form the table. The Owing_Company data displays in the bound control. I can change the text and in Save_Click the RowState is Modified and Row!Owning_company has the changed data. DsForm.HasChanges is False. A simple call in Save_Click daForm.Update(dsForm) does not change the DB. If I update the Row!Owning_Company in code dsForm.HasChanges is now true and daForm.Update changes the data. What am I missing that allows changes made via the bound control to modify the DataSet?

If any settings are changed I need to update the database. For some reason I can't get the code below to update anything. The code throws no errors when it executes, but when I check the database for the updates nothing is changed.
