Is there a way to copy a record from one table to another. Both tables have same structure?

If using SQL, you could use INSERT INTO:

INSERT INTO [destination]
SELECT * FROM [source]
WHERE [RowId] = RowId

If using DDA, you could use something like the following:

using (IVistaDBTableSchema schema = db.TableSchema(sourceTableName))
{
  using (IVistaDBTable sourceTbl = db.OpenTable(sourceTableName, true, true))
  {
    using (IVistaDBTable destinationTbl = db.OpenTable(destinationTableName, true, false))
    {
      // apply filter
      sourceTbl.SetFilter(filterExpression, optimizeFilter);

      // move to first record
      sourceTbl.First();

      while (!sourceTbl.EndOfTable)
      {
        // create new record
        destinationTbl.Insert();

        // copy data
        for (int i = 0; i < schema.ColumnCount; i++)
          destinationTbl.Put(i, sourceTbl.Get(i));

        // save changes
        destinationTbl.Post();

        // advance source to next record
        sourceTbl.Next();
      }
    }
  }  
}

Thanks. I was looking for DDA.
