Data formatting SSN
From Wiki
You should not store unencrypted SSNs in the database. If you do store them and you don't have the dashes but you need to display them then you can use the STUFF function to accomplish that Here is an example, the output will be 111-22-3333
- DECLARE @SSN VARCHAR(11)
- SELECT @SSN ='111223333'
- SELECT STUFF(STUFF(@SSN,4,0,'-'),7,0,'-')
You can also use STUFF to hide the last 4 characters for example.
- DECLARE @SSN VARCHAR(11)
- SELECT @SSN ='111223333'
- SELECT STUFF(@SSN,6,4,'----')
Of course you could have LEFT instead
- DECLARE @SSN VARCHAR(11)
- SELECT @SSN ='111223333'
- SELECT LEFT(@SSN,5) +'----'
