Question

客户端是Ubuntu 14.04.1 LTS与MS SQL Server 2005通信.Ubuntu没有注册域。它与MS SQL Server一样位于本地网络内部。
Perl 5.18.2使用DBI 1.63和DBD :: ODBC 1.52。
已安装FreeTDS 0.92（使用TDS v4.2）和unixODBC 2.2.14。
isql DSN USERNAME PASSWD也不起作用。也许我应该从那开始。我仍然得到同样的错误Unable to connect to data source (SQL-08001).

<小时/> Perl连接信息：

$respdsn="dbi:ODBC:Driver={SQL Native Client};Server=10.20.30.40;".
"UID=$respdbuser;PWD=$respdbpw;Database=r4w_004";
$respdbh=DBI->connect($respdsn);

我可以在命令行使用tsql连接到数据库。但是使用Perl我得到了这个错误：

DBI connect('Driver={SQL Native Client};Server=10.19.1.3;UID=gilson\mwreports;PWD=MR4gilson;Database=r4w_004','',...) failed:
[unixODBC][Driver Manager]Data source name not found, and no default

        DBI::__ANON__[/usr/lib/perl5/DBI.pm:744](undef, undef) called at /usr/lib/perl5/DBI.pm line 747

<小时/> 我的问题：

是＆＃34; {SQL Native Client}＆＃34;在Perl连接字符串中是否正确？它是指odbc.ini或freetds.conf文件中的条目吗？
我在这里失踪了什么？

谢谢。

Answer 1

如果你正在使用FreeTDS，那么你的驱动程序就是FreeTDS而不是＃34; Sql Native Client＆＃34;。

尝试使用此行来获取数据库句柄：

my $dbh = DBI->connect("dbi:ODBC:Driver=FreeTDS;Server=10.20.30.40;database=r4w_004", $respdbuser, $respdbpw);

Answer 2

当我使用tsql可以正常工作但将dbi与perl一起使用时，我遇到了同样的问题。我花了很多时间试图找出问题所在，所以我看到了Adaptive Server的局限性：

名称不能超过30个字符。
第一个字符必须是字母（ASCII从a到z，从A到Z）。
其后的字符必须是字母，数字或下划线（_）。

...所以我尝试将32个字符长的密码更改为30个字符，并且可以使用。

tsql接受长密码，但是perl dbi sybase仅接受30个字符。

用于在端口1433上连接到默认实例的命令：

perl -e 'use DBI;DBI->connect("dbi:Sybase:server=10.0.0.1","sa","max_30_characters_longpassword");'

用于连接到命名实例的命令（使用端口udp 1434查找端口）：

perl -e 'use DBI;DBI->connect("dbi:Sybase:server=10.0.0.1\\SQL2014","sa","max_30_characters_longpassword");'

当您知道sqlserver正在侦听的端口时，用于连接到命名实例的命令：

perl -e 'use DBI;DBI->connect("dbi:Sybase:server=10.0.0.1:60036","sa","max_30characters_long_password");'

我使用tcpdump监视与sqlserver的连接：

tcpdump -qn dst host 10.0.0.1 &

也许它可以帮助某人。谢谢

tsql连接到ODBC，但Perl DBI收到错误
