• BartonFinkle Copy schema from data table to data source?

  DataAdaptor.FillSchema is handy for creating a data table and configuring it to match the schema of an existing table in a data source. But I need to do just the opposite. I have a table that I create progamatically. I create a new SQL database using t-SQL CREATE DATABASE. I want to add a new table to the database with schema matching that of my existing table. I can do it rather laboriously with t-SQL, but some sort of "DataAdapt ...Show All

In some cases only a part of a  class might have changed. I'd want to serialize only the affected ...Show All
