** The data_xxx tables themselves should have no PRIMARY KEY declarations.
** However, OTA is more efficient if reading the rows in from each data_xxx
** table in "rowid" order is roughly the same as reading them sorted by

** words, rows should be sorted using the destination table PRIMARY KEY 
** fields before they are inserted into the data_xxx tables.
