But of course -- just use a negative one as the position to the instr function.
>From the SQL manual:
INSTR searches string for substring.
position is an integer indicating the character of string where Oracle
begins the search. If position is negative, Oracle counts and searches
backward from the end of string.

Please respond
to ORACLE-L
How would you take the same string "/dir1/dir2/test/file.out", and return "file.out". Assume you do not know where the last '/' is or how many there are. What I need is a reverse instr function. Find the last occurrance of '/', not the first.
Can it be done in sqlplus???
