通过dblib使用MSSQL时PDO连接的替代方案

Question

我需要使用PHP连接到远程MSSQL服务器。我已经成功使用dblib连接，但它有一些相当“讨厌”的限制。

我发现它无法获取ntext格式的列行，这里有一个简单的解决方法，但它限制了输出（通过查询将ntext转换为nvarchar），然后我注意到它也有以十进制格式获取行的问题（或者看起来很不幸，一般错误4004对所有东西都会引起不太大的帮助）。

只是有太多的黑客需要，我喜欢，有没有更好的方式来处理这一点，也许不同的DB库，我应该看看我的连接？

值得一提的是，我用mssql_ *取得了巨大成功，但它显然不是一个理想的做法，我希望用PDO保持。

值得注意的事情;

我Debian的运行，我知道微软已经发布了ODBC驱动程序，但它们的驱动程序下载被窃听，因此不工作（至少不能在非RHEL系统似乎）

Answer 1

待办事项不使用dblib/mssql:驱动程序。

如果您使用的是Windows，请使用sqlsrv: driver。 （您必须下载一些DLL--链接的说明）。

如果您使用unix，请使用PDO odbc: driver，最好是unixODBC的风格。在Debian和Ubuntu上，您可以使用简单的apt-get install php5-odbc来获得此驱动程序。

Answer 2

当我执行：

TDSDUMPCONFIG=stdout TDSDUMP=stdout tsql -S <name in TDS.conf> -U '<domain>\<username>' -p 1443 -P <password> 

我得到这个：
