Ubuntu 12.04 LTS 64 + unixODBC 2.3.1 + Informix clientsdk 4.10 + node.js v0.10.20

我会学到很多关于你的问题和答案的解读。Ubuntu 12.04 LTS 64 + unixODBC 2.3.1 + Informix clientsdk 4.10 + node.js v0.10.20

但现在我失去了

正如你可以看到标题，我与Ubuntu 12.04 LTS发挥64 +的unixODBC 2.3.1 + Informix的clientsdk 4.10 + Node.js的v0.10.20 ....

直到我尝试在node.js环境中使用unixODBC和Informix驱动程序进行连接时，每件事情都是正确的。

我对SQLServer没有问题。所以节点没问题，unixODBC也没问题，SQLServer Driver也是。 Informix驱动程序看起来也是正确的，但是。

我可以$ isql -v MYDSN和查询数据库。

但是当节点App试图连接崩溃。

的DSN是真的容易和isql可以玩：

/usr/local/etc/odbc.ini 
[NIFX] 
Driver=/opt/IBM/informix/lib/cli/iclit09b.so 
Server=explotacion 
LogonID=informix 
pwd=enterpass 
Database=data

和玩宽度isql将查找以及

$ isql NIFX 
+---------------------------------------+ 
| Connected!       | 
|          | 
| sql-statement       | 
| help [tablename]      | 
| quit         | 
|          | 
+---------------------------------------+ 
SQL> SELECT COUNT(*) FROM PACIENTES 
+------------------+ 
|     | 
+------------------+ 
| 414396   | 
+------------------+ 
SQLRowCount returns -1 
1 rows fetched 
SQL>

我的节点testifx.js看起来

var Database = require("odbc").Database, 
    db = new Database(), 
    cn="DSN=NIFX" 

db.open(cn, function (err) { 
    if (err) return console.log(err); 

    db.query('SELECT COUNT(*) FROM PACIENTES', [], function (err, data) { 
    if (err) console.log(err); 

    console.log(data); 

    db.close(function() { 
     console.log('done'); 
    }); 
    }); 
});

而结果...

$ node testifx 
{ error: '[node-odbc] SQL_ERROR', 
    message: '[unixODBC][', 
    state: '0' } 
$

任何人都可以帮助我。

什么是错宽度ODBC.INI或者也许把连接字符串中的其他一些parametrers（我托盘都发现赫然出现在谷歌的空间）

感谢真多。

谢谢迈克尔对不起，很长的日志。

我已经做了你说的话。首先登录到跟踪文件中的设置适当的环境中ODBCINST.INI

[ODBC] 
TraceFile = /home/srlopez/Dev/unixODBC.log 
Trace = Yes

其次，运行ISQL -v NIFX，并起到一个命令SELECT COUNT（*）FROM FSIGBLO。我只是指名DSN。

完成右和迹线是：

这些都是我的结论。节点使用unixODBC调用不同的函数。 ISQL呼叫SQLConnect.c和节点呼叫SQLDriverConnectW.c，像这样：

错误发生在哪一行？什么时候执行SELECT或何时打开连接？错误消息不完整，请检查是否无法获取有关错误的更多详细信息。 – ceinmart

在trace中奇怪的是，连接来自'isql'的字符串：'NIFX'是4个字符长，其中来自'node.js'：'DSN = NIFX'的连接字符串长度为9个字符。 –

您可以启用ODBC调用跟踪。首先运行isql以获取有效呼叫的日志。然后对node.js做同样的事情。比较他们应该告诉你问题在哪里。

还有就是我如何启用ODBC在Linux上跟踪Informix的问题和答案：Tracing ODBC calls for Informix Client for Linux

编辑：

从日志似乎node.js使用SQLDriverConnectW()与错误结束：-11005。 Informix显示错误将其描述为“连接字符串属性无效。”。

您可以使用相同的连接字符串为isql：

cn="NIFX"

如果不超过也许工作，你应该添加用户名/密码：

cn="Dsn=NIFX;Uid=myUsername;Pwd=myPassword;"

在Python我经常用它在形式上：

dsn/user/password

您还可以尝试添加连接字符串更多信息just lik e显示在：http://www.connectionstrings.com/informix
