Deleting record gives me dbconcurrency exception

I am trying to delete all the records in a table, but I keep getting a
system.data.dbc oncurrency exception. Is there an easy was to delete all the
records in a sql table?

Here is my code... i get the error on the dataadapter.upd ate:

MessageBox.Show (Me.DataSet11.t blPreReqWorking .Rows.Count)
'get rid of any records in memory
Me.DataSet11.tb lPreReqWorking. Clear()
Me.daPreReqWork ing.SelectComma nd.CommandText = "Select JobNo, ReqNo, SeqNo
From dbo.tblPreReqWo rking"

Me.daPreReqWork ing.Fill(Me.Dat aSet11.tblPreRe qWorking)
MessageBox.Show (Me.DataSet11.t blPreReqWorking .Rows.Count)
Dim myRow As DataRow
For Each myRow In Me.DataSet11.tb lPreReqWorking
myRow.Delete()
Next
'this is where i get the dbconcurrency error
Me.daPreReqWork ing.Update(Me.D ataSet11.tblPre ReqWorking)
'i don't get this far
Me.DataSet11.tb lPreReqWorking. Clear()

Check your UpdateCommand parameters, they are probably either wrong or
missing.

It was something to do with the dataadapter not being setup correctly. I
created a new dataadapter with no parameters... and i was then able to
delete all the records in the table. My original datadapter had parameters
like JobNo = xxx which through off the update command i guess.

Thanks everyone for your help!
