questions regarding sql xlat
Hello list,
I am trying to use some internal database function to calculate the
Session-Timeout.
If I set the value for Session-Timeout to a integer like 123, its
correctly delivered as answer to my request.
If I try to use sql xlat I will get the answer:
Error: rlm_sql: Failed to create the pair: Unknown value %{sql:SELECT
disctime.time FROM `disctime` WHERE disctime.user = %{User-Name}} for
attribute Session-Timeout
Sun Apr 19 20:11:03 2009 : Error: rlm_sql (sql): Error getting data from
database
I tried several different things: Use a select statement to query the
integer directly. I ends up in the same error. I am using:
- freeradius: FreeRADIUS Version 2.0.4, for host i486-pc-linux-gnu,
built on Sep 7 2008 at 23:35:34
- Debian GNU/Linux 5.0 (lenny)
- postgresql 8.3.7-0lenny1

*sigh* single quotation marks around %{User-Name}, it's still a string

So this should work? ATM I am nearly sure that this could never work,
since the 1st query will deliver the string, that rlm_sql should expand
with another query.
But it would be great if it will work :-)

rlm_sql does recursive xlat, all xlat expansions in the SQL query are
done before the query string is passed off to the SQL libraries. The
xlat parser is just looking for a string bounded by %{ }.
Your query should be:
%{sql:SELECT disctime.time FROM `disctime` WHERE disctime.user =
'%{User-Name}'}
It's not a problem in FreeRADIUS it's a problem in your SQL syntax :)

Both :-)
I missed some backticks:
`%{sql: select sessionto('%{User-Name}') }`
is working. sessionto is a postgres function which calculates the
session-timeout.
Thanks
