I need to format data in a sql column that is currently entered like this:
Z04000002003.7
The desired output of this would be:
Z04/000/002/003.7
Every time a user enters data like this Z04000002003.7. The next time the user opens the record it would have automatically formatted it to display Z04/000/002/003.7.
If you want to insert the slashes on INSERT or UPDATE (when the string gets into the database) or SELECT, you can do that in TSQL with a somewhat clumsy string expression:
and so on, but I agree with other respondents that it may be a better architecture to perform such transformations “closer to the user” (in the UI, or perhaps in a business logic layer if those slashes are in fact part of the business logic, but UI looks likelier).
