- Suppose you want to replace all the Social Security numbers in a column with 999999999. You can use the Fixed Number masking format and provide this number as input.
- Alternatively, you can combine multiple basic masking formats to mask a column value. For example, you can use the Fixed Number masking format to ensure that the masked value starts with 990. Then, you can use the Random Number masking format to randomly generate the remaining seven digits.
