hi, just want to manage accounting on mysql so i coyed the schema.sql in /etc/freeradius, did mysql -u root -p accounting < schema.sql and i got this. *ERROR 1064 (42000) at line 17: 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 '[radacct] ( [RadAcctId] [numeric](21, 0) IDENTITY (1, 1) NOT NULL , [AcctSessi' at line 1* i compare the schema.sql to one at http://wiki.freeradius.org/MS-SQL_DDL_script , nothing changed. somebody as a clue? thanks
