How to select a column and replace last digits of the result

Question

I'm trying to mask the last 2 digits of a column so I can generate a report for a client, but dont want him to get the phone numbers of my data base.

Found some results here but none of them does what I want.

How can I do this ?

Answer 1

I was able to find an answer and change it to do what I want, here's what I did to mask the phone number.

SELECT 
CONCAT( LEFT( phone, LENGTH( phone ) -2 ) ,  'xx' ) 
FROM TABLE

The -2 is to indicate that I want the last 2 numbers replaced and the XX is what its going to show instead of the 2 numbers, this way the numbers are masked.

I'm just sharing what I'm learning, sorry if theres an aswer for this already in another way.

Answer 2

从表中选择REPLACE（column，SUBSTRING（column，-2），'xx'）;
