Mysql format a string like XXXXXXXXXXXX to XX-XX-XXXXXXX-X

Question

I need a string that looks like XXXXXXXXXXXX to look like this XX-XX-XXXXXXX-X. I don\'t know of a function or pattern tool in MySQL that can do this. Do you?

Answer 1

Take a look at this, I think that's exactly what you are look for.

MySQL output masking (i.e. phone number, SSN, etc. display formatting)

Answer 2

One way to do that, in MySQL is to use an expression with the SUBSTRING and CONCAT functions, Like this:

CONCAT(
  SUBSTR(str,1,2), 
  '-',
  SUBSTR(str,3,2),
  '-',
  SUBSTR(str,5,7),
  '-',
  SUBSTR(str,12,1)
 ) AS formatted_str

Answer 3

if the length of the string is fix, you can just simple string manipulation

SELECT pat,
       CONCAT_WS('-', SUBSTR(pat,1,2), 
                       SUBSTR(pat,3,2),
                       SUBSTR(pat,5,7),
                       RIGHT(pat,1))
FROM   tableName
