Updating problem

I have created a table by running a script from my code. I have also
created a matching dataset
loaded with data for this new table. I now have to get the data in the
dataset into the table.

I figured I would create a SqlDataAdapter and a SqlCommandBuilder and then
use ado.net to do my

update as follows....
sql = "SELECT SubID, Code, State, Market, CrewCount, DayRate, NightRate,
HolidayRate " & _
"FROM(SubServices)"
Dim da As New SqlDataAdapter(sql, cn)
Dim cb As New SqlCommandBuilder(da)
da.Update(newSSDS)

but this gets the following exception...
system.invalidOperationException

Unable to find tableMapping['Table'] or datatable 'Table'

Why am I getting this? Is there an easier way to do this?
TIA

Where in your code do you actually populate dataset with data? You need to use .Fill method of dataAdapter to do that.

something like this:
da.Fill(Mydataset, "TableName")

I did that of course. I didn't want to post my entire program. I built the
dataset in other code.
