[Haskell-cafe] a question about Database.HDBC.ODBC

[Changying Li]

I want to use hdbc to connect my mysql test db. so I set up my
/etc/odbcinst.ini :
[MySQL]
Description     = ODBC Driver for MySQL
Driver          = /usr/lib/libmyodbc.so
Setup           = /usr/lib/libodbcmyS.so
FileUsage       = 1

and /etc/odbc.ini:
[test]
Description     = MySQL database test
Driver          = MySQL
Server          = localhost
Database        = test
Port            = 3306
User            = root
Socket          = /tmp/mysql.sock
Option          =
Stmt            =

user chylli at localhost must use password to connect mysql. other users needn't.
I connect db like this:
Prelude Database.HDBC.ODBC Database.HDBC> handleSqlError (connectODBC "DSN=test")
*** Exception: user error (SQL error: SqlError {seState = "[\"HY000\"]", seNativeError = -1, seErrorMsg = "connectODBC/sqlDriverConnect: [\"1045: [unixODBC][MySQL][ODBC 3.51 Driver]Access denied for user 'chylli'@'localhost' (using password: NO)\"]"})
Prelude Database.HDBC.ODBC Database.HDBC> handleSqlError (connectODBC "DSN=test;UID=chylli")
Prelude Database.HDBC.ODBC Database.HDBC> 

in another term:
mysql> show processlist;
+----+-------------+-----------+------+---------+------+-------+------------------+
| Id | User        | Host      | db   | Command | Time | State | Info             |
+----+-------------+-----------+------+---------+------+-------+------------------+
| 31 | chylli¶è | localhost | test | Sleep   | 1483 |       | NULL             | 
| 43 | root        | localhost | test | Sleep   |  116 |       | NULL             | 

my question is:
1. why not HDBC.ODBC use configuration in /etc/odbc.ini ? if is use,
then connectODBC "DSN=test" should use root as user without password and
it should succeed.

2. when using UID=chylli, why the user in 'show processlist' is not
chylli but 'chylli¶è' ?  if it use account 'chylli', that connection
should fail. but in fact it succeed !!!
