Error connecting Erlang and mysql odbc - mysql

Question

I have an Amazon linux instance on which i have installed a server named ejabberd
Inside it I have a code written in erlang as (db.erl).
-module(db).
-export([connection/0]).
connection()->
odbc:start(),
ConnectionString = "DSN=qaz;UID=root;PWD=abc",
{ok, Ref} = odbc:connect(ConnectionString, []),
Ref.
But when I this code is about to run I get an error as
[error] gen_server myapp terminated with reason: no match of right hand
value {error,"[unixODBC][Driver Manager]Can't open lib
'/usr/lib/libmyodbc5.so' : file not found SQLSTATE IS: 01000 Connection to
database failed."} in db:connection/0 line 15

I have edited my /etc/odbc.ini and /root/.odbc.ini with following configurations
[ODBC Data Sources]
qaz= ODBC for MySQL
[qaz]
Driver = /usr/lib64/libmyodbc5.so
Description = ODBC for MySQL
SERVER = localhost
PORT = 3306
USER = root
Password = abc
Database = mydb
and my odbcinst.ini file looks like this
# Example driver definitions
# Driver from the postgresql-odbc package
# Setup from the unixODBC package
[PostgreSQL]
Description = ODBC for PostgreSQL
Driver = /usr/lib/psqlodbc.so
Setup = /usr/lib/libodbcpsqlS.so
Driver64 = /usr/lib64/psqlodbc.so
Setup64 = /usr/lib64/libodbcpsqlS.so
FileUsage = 1
# Driver from the mysql-connector-odbc package
# Setup from the unixODBC package
[MySQL]
Description = ODBC for MySQL
Driver = /usr/lib/libmyodbc5.so
Setup = /usr/lib/libodbcmyS.so
Driver64 = /usr/lib64/libmyodbc5.so
Setup64 = /usr/lib64/libodbcmyS.so
FileUsage = 1
[MySQL ODBC 5.3 Unicode Driver]
Driver = /usr/lib/libmyodbc5w.so
UsageCount = 1
[MySQL ODBC 5.3 ANSI Driver]
Driver = /usr/lib/libmyodbc5a.so
UsageCount = 1
And when I run command
isql qaz [root [abc]]
I get an error as
[ISQL]ERROR: Could not SQLConnect
Can Anyone tell me the issue and guide me with the correct way to set up odbc configurations in linux
I have done it successfully on windows though, but I am not too familiar with linux.
Thank you in advance

Answer 1

It's the ODBC driver (ODBC Connector) that is provided by mySQL. Did you pre-install the driver? Search how to install mysql odbc driver.
However, I would recommend using another mysql driver, like mysql/otp and not ODBC driver. I've had problems using the ODBC driver with mySql.
