What is a Larva™ Validation Function?
A. A Validation Function allows validating a column value during a migration process. For instance, suppose you only want migrating data with: 1000 <= ID <= 5000 from the table: PRODUCTS (ID, DESCRIPTION) Instead of creating a new SQL VIEW in your database with the specified delimitation, you may create a simple validation rule to delimitate the required range for the ID column.
