Hello.

1. Upgraded to 2.2.9:

#freeradius -v

freeradius: FreeRADIUS Version 2.2.9, for host x86_64-pc-linux-gnu,
built on Jan 15 2016 at 12:53:27
Copyright (C) 1999-2015 The FreeRADIUS server project and contributors.

2. The error persists:
...............

Fri Jan 15 13:17:22 2016 : Info: [sql] 	expand: SELECT 'simult'
groupname FROM TABLE(SET {1}) -> SELECT 'simult' groupname FROM
TABLE(SET {1})
Fri Jan 15 13:17:22 2016 : Debug: query:  SELECT 'simult' groupname FROM
TABLE(SET {1})
Fri Jan 15 13:17:22 2016 : Error: rlm_sql_unixodbc: 07009

3. I want implement simultaneous use check by username. 
(Device send periodically accounting packets to freeradius. He writes it
into the Informix.)

I can do this only after receiving "Simultaneous use := 1" to my
request , and no further?
