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

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
