How to prevent one of  the field in clientdataset from updating onto the db?
I set the ProviderFlags( pfInUpdate,pfInWhere etc) for that 
field('myvirtualcolumn') all to false and my DataSetProvider update mode 
i set to upWhereChanged or upWhereKey but it seems doesnt solve my 
problem it keeps returning error
 'Invalid column name "myvirtualcolumn'...'..
Any idea how to solve this problem?

Thanks.
