ports安装 MySQL
cd /usr/ports/databases/mysql51-server; make install clean
安裝unixODBC
cd /usr/ports/databases/unixODBC; make install clean
安裝MySQL ODBC Driver
cd /usr/ports/databases/mysql-connector-odbc; make install clean
安裝MS SQLServer ODBC Driver
cd /usr/ports/databases/freetds-msdblib; make install clean
/usr/local/etc/odbcinst.ini 指定安裝的odbc library位置，例如
==================================================
[MySQL]
Description = ODBC Driver for MySQL
Driver = /usr/local/lib/libmyodbc3.so
Setup = /usr/local/lib/libodbcmyS.so
FileUsage = 1
CPTimeout =
CPReuse =
[FreeTDS]
Description = ODBC Driver for MS SQL server /Sybase v0.63
Driver = /usr/local/lib/libtdsodbc.so
Setup = /usr/local/lib/libtdsS.so
UsageCount = 2
=======================================
/usr/local/etc/odbc.ini 整定DSN (Data Source Name)，例如
================================================
[MySQL-test]
Description = MySQL database test
Driver = MySQL
Server = localhost
Database = databasename
Port = 3306
Socket =
Option =
Stmt =
[MS-SQLServer-test]
Description = MS SQLServer(OR Sybase) database test
Driver = FreeTDS
Server = IP Address
Port = PortNumber(1433)
Database = databasename
Trace = No
========================================================
测试程序：isql
＊＊＊
NOTE:
亦可以由/usr/ports/databases/freetds编译**，但是注意TDS Version內定为5.0，版本适用范围请参阅下列网址
测试以8.0连接SQL EXPRESS( SQL Server 2005)，能順利连接但无法下SQL指令，改用7.0帽正常运作。
**
make TDS_VER=7.0 -DWITH_MSDBLIB install clean
