Hi, I was trying to use nibblebill as billing control of my FS. I have configured the odbc and the nibblebill configuration. When I tried to call, the query looks ok. But when I hanged up the call, it seems like there is something wrong with the database connection, since it's not updating the database at all. I got error message on CLI 2012-11-01 10:51:00.559472 [ERR] switch_odbc.c:494 ERR: [UPDATE accounts SET usage=usage-0.476000 WHERE user='1001'] [STATE: 42000 CODE 1064 ERROR: [unixODBC][MySQL][ODBC 5.1 Driver][mysqld-5.5.24-0ubuntu0.12.04.1]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'usage=usage-0.476000 WHERE user='1001'' at line 1 ] 2012-11-01 10:51:00.559472 [ERR] mod_nibblebill.c:343 ERR: [UPDATE accounts SET usage=usage-0.476000 WHERE user='1001'] [] 2012-11-01 10:51:00.559472 [CRIT] mod_nibblebill.c:542 Failed to log to database! 2012-11-01 10:51:00.559472 [DEBUG] mod_nibblebill.c:383 Doing lookup query [SELECT usage AS nibble_balance FROM accounts WHERE user='1001'] 2012-11-01 10:51:00.559472 [ERR] mod_nibblebill.c:385 ERR: [SELECT usage AS nibble_balance FROM accounts WHERE user='1001'] [STATE: 42000 CODE 1064 ERROR: [unixODBC][MySQL][ODBC 5.1 Driver][mysqld-5.5.24-0ubuntu0.12.04.1]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'usage AS nibble_balance FROM accounts WHERE user='1001'' at line 1 ] 2012-11-01 10:51:00.559472 [ERR] mod_nibblebill.c:386 Error running this query: [SELECT usage AS nibble_balance FROM accounts WHERE user='1001'] Could anybody help me solve this issue?
