I need to replace the middle underscores so that it displays it as date i.e.


Can some one please suggest a simple update query for this.

The Number of Underscores would be same for all the values in the column but the length will vary for example some can have

Here's one ugly way:

select stuff(stuff(s, idx+3, 1, '-'), idx+6, 1, '-')
from   (
       select s, patindex('%_[0-1][0-9]_[0-3][0-9]_20[0-2][0-9]_%', s) idx
       from   (
              select 'AAAxZZZZ_7890_10_28_2014_123456.jpg' s union all
              select 'AAA_q10WRQ_001_10_28_2014_12.jpg'
              ) d
       ) d



this version will only work with dates between years 2000 an 2029
