Question

我尝试使用FreeTDS和unixODBC将MSSQL服务器连接到ubuntu 14.04。

我可以使用tsql连接：

~$ tsql -S MSSQL -U <username> -P <password>

这是正常的。

尝试使用isql时，我会得到以下内容

isql -v MSSQL <username> <password>
[S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source
[ISQL]ERROR: Could not SQLConnect

这是我的配置。

ODBC.INI

[MSSQL]
Driver = FreeTDS
TDS_Version = 8.0
Server = <server>
Instance = dev
Database = <database>

ODBCINST.INI

[FreeTDS]
Description = FreeTDS
Driver = /usr/local/lib/libtdsodbc.so
Setup = /usr/local/lib/libtdsodbc.so
Trace = Yes
TraceFile = /tmp/freetds.log
ForceTrace = Yes

freetds.conf

#   $Id: freetds.conf,v 1.12 2007/12/25 06:02:36 jklowden Exp $

# This file is installed by FreeTDS if no file by the same
# name is found in the installation directory.

# Global settings are overridden by those in a database
# server specific section
[global]
        # TDS protocol version
#       tds version = 4.2

        # Whether to write a TDSDUMP file for diagnostic purposes
        # (setting this to /tmp is insecure on a multi-user system)
;       dump file = /tmp/freetds.log
;       debug flags = 0xffff

        # Command and connection timeouts
;       timeout = 10
;       connect timeout = 10

        # If you get out-of-memory errors, it may mean that your client
        # is trying to allocate a huge buffer for a TEXT field.
        # Try setting 'text size' to a more reasonable limit
        text size = 64512

# A typical Sybase server
[egServer50]
        host = symachine.domain.com
        port = 5000
        tds version = 5.0

# A typical Microsoft server
[egServer70]
        host = ntmachine.domain.com
        port = 1433
        tds version = 7.0

[MSSQL]
        host = <host>
        instance = dev
        tds version = 8.0

我认为这个问题是由司机引起的，我不相信我应该得到一个错误，说司机不可执行。这是osql输出：

osql -S MSSQL -U <username> -P <password>
checking shared odbc libraries linked to isql for default directories...
strings: '': No such file
        trying /tmp/sql ... no
        trying /tmp/sql ... no

"Server" found, not using freetds.conf
Server is <server_name>

Configuration looks OK.  Connection details:

                   DSN: MSSQL
              odbc.ini: /home/<user>/.odbc.ini
                Driver: /usr/local/lib/libtdsodbc.so
       Server hostname: <host>
               Address: <ip_address>

Attempting connection as <username> ...
+ isql MSSQL <username> <password> -v
[S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source
[ISQL]ERROR: Could not SQLConnect

感谢任何帮助，谢谢。

Answer 1

我找到了问题的答案。我需要在odbc.ini文件中将实例添加到服务器，如此

MSSQL]
Driver = FreeTDS
TDS_Version = 8.0
Server = <server\dev>
Database = <database>

这让我执行isql。

ubuntu tsql工作和isql无法正常工作
