Question

I have a column with values like this:

01709100011

I need to transform it to:

017.091.0001-1

The values have always the same characters number.

Both columns are varchar

Thanks in advance for any help.

Answer 1

SELECT CONCAT(SUBSTRING(test, 1,3),'.',SUBSTRING(test,4,3),'.',SUBSTRING(test,7,4),'-',SUBSTRING(test,11,1)) FROM test;

In the above example I used the table test and values in column test.
