Compare Editions

Data Compare allows you to compare the data between two different tables, whether these are in the same database or different databases.

  • you can compare either tables or the results of a query
  • tables can be in different databases; even databases of different types
  • 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 and to use little memory. A speed of 10,000 rows per second is not uncommon. Compare 1 million rows in a few minutes!
  • Data Compare can be run in batch mode for unattended resynchronization of data
