linux connect mssqlserver

let the linux programm connect to mssqlserver, install the third library - freetds.
here are the steps to make it work, don't ask why, just have a try.

 

1,setup unixODBC
./configure --prefix=/user/local/unixODBC
make
make install

 

2,setup freetds
./configure --prefix=/user/local/freetds --with-unixodbc=/user/local/unixODBC --with-tdsver=8.0 --enable-gui=no --enable-msdblib
make
make install

 

3,configure freetds
vi etc/freetds.conf
 [MyServer2k5]
 host = 192.168.90.5
 port = 1433
 tds version = 8.0
 client charset = GBK

 

./freetds/bin/tsql -S MyServer2k5 -H 192.168.90.5 -p 1433 -U sa -P 123456
./freetds/bin/tsql -S MyServer2k5 -U sa -P 123456 -D test

 

4,configure unixODBC
vi etc/odbcinst.ini
 [TDS]
 Description = MS-SQL Server
 Driver = /user/local/freetds/lib/libtdsodbc.so
 Setup = /user/local/freetds/lib/libtds.so
 FileUsage = 1

 

vi etc/odbc.ini
 [test];DSN
 Driver = TDS
 Servername = MyServer2k5
 Server = 192.168.90.5
 Database = test
 Port = 1433
 Socket =
 Option =
 Stmt =

 

vi /root/.odbc.ini
 [test]
 Driver = TDS
 Servername = MyServer2k5
 Server = 192.168.90.5
 Database = test
 Port = 1433
 
./unixODBC/bin/isql -v test sa 123456
