Gigawords

Hello, I'm using rlm_sql_log in freeradius 1.1.4. In order to correctly work with acct-input/ output gigawords, I've replaced '%{Acct-Input-Octets}' with '%{%{Acct-Input-Gigawords}:-0}' << 32 | '%{%{Acct-Input-Octets}:-0}' in the rlm_sql_log conf, but this results in invalid queries like: "update radacct set... ...acctiputoctets = 0 << 32 | 98..." Looks like the rlm_sql_log module was not compiled to parse that sintax. What can I do, please (besides create a procedure on the DB to treat that)? Thank you very much. Guilherme Franco
