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)
                            Version: freetds v0.91
             freetds.conf directory: /usr/local/freetds/etc

                           unixodbc: yes
              SSPI "trusted" logins: no
                           Kerberos: 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
Description = DSN
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：

1 2 3 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

go

select name from sys.databases

go

select * from sys.tables

go
