Question

in my DB I have a column given paths like :

• \myserver\mydir1\dir2\Atest.txt
• \myserver\mydir1\dir2\Btest.txt

At the end I should update a column with the first character after the last “\” delimiter , therefore “A” and “B” in this example.
How can I get this?

Thanks a lot

Answer 1

select substring(YourColumn, len(YourColumn)-charindex('\', reverse(YourColumn))+2, 1)
from YourTable

You have not specified what DBMS you are using. To make this work you need to have these functions available or something similar.

• substring
• len
• charindex
• reverse
