Implementing Column Masks is not as trivial, you should read the following
redpaper first:
https://www.redbooks.ibm.com/redpapers/pdfs/redp5110.pdf
There is also an example in chapter 3.4 for only masking a part of the whole
column content.

Subject: How to mask a variable size value
Hello all, I'd like to seek a suggestion on how using SQL mask a numeric
value, the value can be of different sizes so I'd like to only list the last
4 numbers and mask '*' the rest, sample:
I'd use a Select statement and select the field but before displaying it I
want to mask it and only allow for the last 4 digits to be readable
1234567890 mask as ******7890 (six asterisks from the beginning)12345678 as
****5678 (four asterisks) thanks in advanceRamon S.
