freetds安装好之后可以查看配置：

root@localhost:/usr/local/freetds/bin# ./tsql -C
Compile-time settings (established with the "configure" script)

Sybase binary compatibility: no
Thread safety: yes
iconv library: yes
TDS version: 7.0
iODBC: no
unixodbc: yes
SSPI "trusted" logins: no

freetds中配置以下内容：

vim /usr/local/freetds/etc/freetds.conf

[myserver]
host = mdb.zz.51fanli.it
port = 1433
tds version = 7.0

unixODBC中配置：

/usr/local/unixODBC/etc/odbc.ini

为以下内容：

[TEST1dsn]
Driver = mssql

Trace = No
Servername = myserver
Database = testdb
UID = trace

测试freetds ：

root@localhost:/usr/local/freetds/bin# ./tsql -S myserver-D target_db -U trace -P trace
locale is "LC_CTYPE=en_US.UTF-8;LC_NUMERIC=zh_CN.UTF-8;LC_TIME=zh_CN.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=zh_CN.UTF-8;LC_MESSAGES=en_US.UTF-8;LC_PAPER=zh_CN.UTF-8;LC_NAME=zh_CN.UTF-8;LC_ADDRESS=zh_CN.UTF-8;LC_TELEPHONE=zh_CN.UTF-8;LC_MEASUREMENT=zh_CN.UTF-8;LC_IDENTIFICATION=zh_CN.UTF-8"

经常用的tsql语法如下：

4

5

说明：列出数据库里所有的表名 
select name from sysobjects where type='U' 
 
说明：列出表里的所有的列 
select name from syscolumns where id=object_id('TableName')

1

select name from sys.objects where type='U' 

其中：

U 指的是用户创建的表。
S 指的是系统表。
TR 指的是触发器，

select * from sys.databases

select name from sys.databases

select * from sys.tables
