generates a number and retrieves a dictionary row based on the serial number from the dictionary. It generates a hash key for repeatable masking or a random number for non-repeatable masking. You can configure an additional lookup condition if you configure repeatable masking.
You can create a generation rule to load the dictionary into target databases. The binary data type contains a serial number column that increases performance. You can configure serial number for relational databases when you create a data generation rule for binary data type.
