解决：

查看TDS version

>> tsql -C
Compile-time settings (established with the "configure" script)
                            Version: freetds v0.91
             freetds.conf directory: /usr/local/freetds/etc
     MS db-lib source compatibility: yes
        Sybase binary compatibility: no
                      Thread safety: yes
                      iconv library: yes
                        TDS version: 7.1
                              iODBC: no

              SSPI "trusted" logins: no

查看freetds.conf文件

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

添加相应的版本信息

# A typical Microsoft server
[egServer71]
        host = ntmachine.domain.com
        port = 1433
        tds version = 7.1

查看数据源文件

>> vim /etc/tds.datasource.template 

修改TDS_Version

TDS_Version          = 7.1

查看odbc.ini文件

>> vim /etc/odbc.ini

修改TDS_Version

TDS_Version          = 7.1
