  • you can specify which columns are compared, and map which column compares to which
  • you can generate a script to resynchronize the tables
  • has a Compare Multiple Tables window for comparing all the tables in a schema
  • Data Compare is optimized to run fast; you can compare tables with millions of rows

Data Compare can generate a script to resynchronize the contents of the tables

  • you can specify which table resyncs to which
