mysql连接oracle补偿方案—odbc驱动

环境：

MYSQL服务器：mysql  5.1.55 64位

ORACLE服务器 : oracle 10g 64位

安装

1.安装数据源驱动（ODBC）64位

 Connector/ODBC 5.3.14 ：https://dev.mysql.com/downloads/connector/odbc/5.3.html

2.打开 ODBC 数据源：

打开后选择系统DSN：

选择：ANSI Driver

配置完成后点击ok就行

3.在cmd 验证一下，输入dg4odbc

配置oracle

1.透明网关配置

找到你的oracle的安装目录的initdg4odbc.ora文件，然后复制一份，命名规则是：init+sid.ora，所以就是initmysqlodbc.ora；

 initmysqlodbc.ora（斜体加粗部分）

HS_FDS_CONNECT_INFO = mysqlodbc
HS_FDS_TRACE_LEVEL = off

 2.listener.ora配置（斜体加粗部分）

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = orcl)
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = F:product11.2.0dbhome_1)
      (ENVS = "EXTPROC_DLLS=ONLY:F:product11.2.0dbhome_1inoraclr11.dll")
    )
    (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = F:product11.2.0dbhome_1)
      (SID_NAME = orcl)
    )
    (SID_DESC =
      (SID_NAME = mysqlodbc)
      (ORACLE_HOME = F:product11.2.0dbhome_1)
      (PROGRAM = dg4odbc)
    )
  )

3.sqlnet.ora（斜体加粗部分）

SQLNET.AUTHENTICATION_SERVICES= (NONE)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

 4.tnsnames.ora（斜体加粗部分）

mysqlodbc =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = mysqlodbc)
    )
    (HS = OK)
  )

 5.数据库测试

在数据执行以下语句

create public database link mysqlodbc connect to "admin" identified by "admin" using 'mysqlodbc';

admin/admin为mysql数据库账号密码

执行查操作

SELECT *  FROM  tb_hisdata@mysqlodbc

SELECT *  FROM  tb_hisdata@mysqlodbc where "sfvalue"!='0';

注意！注意where子句列名加"，不加我电脑上报列名不存在！
