The equivalent will be substr in one of it's many forms

SUBSTR(char, m [, n])

Returns a portion of Char, beginning at character M, N characters long.

If M is positive, Oracle counts from the beginning of Char to find the first character.
if M is negative, Oracle counts backwards from the end of Char. If N is omitted, Oracle returns all characters to the end of Char.

Please don't laugh. What is the equivalent of a Right() function in Oracle? I want to be able to sort a column numerically whose string contents takes the format "v1, v2, v3, v4". I was after something like:

ORDER BY Cast(Right(lt_tk_id, Length(lt_tk_id - 1)) as int)

but it's not playing nice. Order by Right(lt_tk_id, 1) gives the same error, so I assume that's where it's falling down. I've searched everywhere I can think of for "right function", Oracle online docs, Enterprise Manager docs, Google, but nothing seems to come close.

BTW, is it my imagination or do the docs leave a lot to be desired?

Thanks
