急急急求！！！！windows下oracle远程访问Mysql的问题

[icefoxbin]

我是按照下面的这个步骤学习的，到数据库链接已创建已经成功了，就是select查询语句出不来。请大侠指教


创建oracle访问mysql的数据链路步骤2008-08-08 14:32Microsoft Windows XP [版本 5.1.2600]

(1)登陆到mysql
C:\Documents and Settings\Administrator>mysql -h localhost -u root -p
Enter password: *****
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 69
Server version: 5.0.51a-community-nt MySQL Community Edition (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
(2)创建数据库
mysql> create database oracle;
Query OK, 1 row affected (0.00 sec)
(3)创建被访问的mysql用户
mysql> grant all privileges on oracle.* to 'orauser'@'%' identified by 'orauser'
with grant option;
Query OK, 0 rows affected (0.00 sec)

mysql> exit
Bye
(4)登陆该用户，并测试
C:\Documents and Settings\Administrator>mysql -h localhost -u orauser -p
Enter password: *******
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 70
Server version: 5.0.51a-community-nt MySQL Community Edition (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> use oracle;
Database changed
mysql> create table test(tid integer,tname varchar(20));
Query OK, 0 rows affected (0.06 sec)

mysql> insert into test(tid,tname)values(1,'byf');
Query OK, 1 row affected (0.03 sec)

mysql> insert into test(tid,tname)values(2,'others');
Query OK, 1 row affected (0.02 sec)

mysql> select * from test;
+------+--------+
| tid | tname |
+------+--------+
| 1 | byf |
| 2 | others |
+------+--------+
2 rows in set (0.00 sec)

mysql>
(5)安装mysql odbc driver 3.51并设置odbc数据源
data source name:mysqlora
server:localhost
user: orauser
password:orauser
database:oracle
(6)配置初始化参数%ORACLE_HOME%/admin/initmysqlora.ora
HS_FDS_CONNECT_INFO =mysqlora
HS_FDS_TRACE_LEVEL = on
(7)配置%ORACLE_HOME%/newtwork/admin/tnsname.ora
mysqlora=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(CONNECT_DATA =
( SID= mysqlora))
(HS=OK)
)
(8)配置%ORACLE_HOME%/newtwork/admin/listener.ora
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = oradb)
(ORACLE_HOME = D:\oracle)
(SID_NAME = oradb)
)
(SID_DESC =
(PROGRAM = hsodbc)
(ORACLE_HOME = D:\oracle\)
(SID_NAME = mysqlora)
)
)
(9)建立oracle到mysql的数据链路，并测试

C:\Documents and Settings\Administrator>sqlplus /nolog

SQL*Plus: Release 9.2.0.1.0 - Production on 星期五 8月 8 14:17:49 2008

Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.

SQL> conn byf/1234;
已连接。

SQL> create database link mysqlora
2 connect to "orauser" identified by "orauser" using 'mysqlora';

数据库链接已创建。

SQL> select * from test@mysqlora;

tid tname
---------- --------------------
1 byf
2 others

mysql,关注下，不太熟悉。

[raise_ch]

select * from "test"@mysqlora;

就可以了。数据库名，包括字段名都要加双引号
