Configure HS talk to mysql through ODBC

Question

Hello
Running 10g rel2 on Linux 64bit. Need to dblink to mysql 5.
Configured:
/etc/odbc.ini
[myodbc]
Driver = /usr/lib64/libmyodbc.so
Description = MyODBC 2.50 Driver DSN
SERVER = 209.71.254.40
PORT = 3306
USER = posman
Password = posman
Database = poseidon
OPTION = 0
SOCKET =
Listener.ora
(SID_DESC=
(PROGRAM=hsodbc)
(SID_NAME=myodbc3)
(ORACLE_HOME=/opt/oracle/product/10.2.0/rtbrs3)
(ENVS=LD_LIBRARY_PATH = /opt/oracle/product/10.2.0/rtbrs3/lib32:/lib:/usr/lib64)
Tnsnames.ora
HSODBC =
(DESCRIPTION=
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = TCP)
(HOST = everest.ca)
(PORT = 1521)
(CONNECT_DATA =
(SID= myodbc3)
(HS=OK)
inintmyodbc3.ora
HS_FDS_CONNECT_INFO = myodbc3
HS_FDS_TRACE_LEVEL = off
When I do tnsping HSODBC is works.
I create the DBLINK and that works.
I test the dblink and it fails with
SQL> select * from "emp"@testdb;
select * from "emp"@testdb
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from TESTDB
Please help

Answer 1

we had problems with the * wildcard and also with aliases and synonyms for table joins.
make them simple like this: select "column_name" from table_name@testdb;
and make a separate view for each query then use a query to join the views in Oracle.
