Never mind, the second version works. The error was due to a
parenthesis issue.

Subject: [firebird-support] Everything but last character

SELECT
t.DATA,
SUBSTRING(LTRIM(RTRIM(t.DATA)) from 1 FOR
STRLEN(LTRIM(RTRIM(t.DATA))-1),
SUBSTR(LTRIM(RTRIM(t.DATA)), 1, (STRLEN(LTRIM(RTRIM(t.DATA))-1)))
from
TBL t

I'm trying to get all the characters in a field except for the last one.
The first attempt using 'SUBSTRING' returns an error that the token
'STRLEN' after 'FOR' is unknown.
The second one says 'expression evaluation not supported.'

How can I accomplish this?
