Oracle : SQL with REGEXP and RTRIM for Oracle 8i

Question

I have this RTRIM and REGEXP function in Oracle SQL query which is working fine in Oracle 10g but is not working in Oracle 8i. How can I convert the following statement to something working in both Oracle 8i and 10g and still having the same result.

RTRIM(regexp_substr(table.column1, '([^/]+\.)'), '.')

Thanks for the help.

Answer 1

I found the answer :

    SUBSTR(table.column1, INSTR(table.column1, '/', -1) + 1,
    INSTR(table.column1, '.') - INSTR(table.column1, '/', -1) - 1)
