Question

如果我在mac上运行程序（MBA运行的小牛队），我有一段像魅力一样的代码。如果我将代码移动到Windows框（Windows Server 2008 R2 64位），我会在SQL查询本身上收到错误（如下所示）。该错误表示“，”附近存在语法错误。

我正在运行的代码如下：

    try:
      cur.execute("SELECT * FROM dbo.IPAM_Node as A \
        FULL OUTER JOIN IPAM_NodeAttrData as B ON A.IPNodeId = B.IPNodeId \
        FULL OUTER JOIN IPAM_Group as C on A.SubnetId = C.GroupId \
        FULL OUTER JOIN IPAM_GroupAttrData as D on C.GroupId = D.GroupId \
        WHERE IPAddress IN (%s);",(Hosts_as_Tuples,))
      allrows = cur.fetchall()
      print 'allrows:', allrows

此代码在MAC上不起作用，直到我在“WHERE”子句的末尾添加了“，”。这是Windows库似乎反对的地方。我已经尝试取出“，”并且程序运行正常，但它没有正确评估元组。

我尝试了各种建议，例如使用“”“ - 无效或改变行为。

运行时错误如下所示：

根据版本方法，两个地方的库都在同一个版本上。如下：

在Mac上：

isp-pc:site-packages matingara$ python
Python 2.7.5 (v2.7.5:ab05e7dd2788, May 13 2013, 13:18:45)

>>> import pymssql
>>> pymssql.__version__
'2.0.0'

在Windows上（尝试了两个版本的python）：

C:\Python27>python.exe
Python 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win

Answer 1

你检查过sql server上的消息了吗？（这两台机器上的数据库连接是否正常？）

另外，您是否尝试在调用execute之前评估字符串？类似的东西：

queryString = "SELECT * FROM dbo.IPAM_Node as A \
    FULL OUTER JOIN IPAM_NodeAttrData as B ON A.IPNodeId = B.IPNodeId \
    FULL OUTER JOIN IPAM_Group as C on A.SubnetId = C.GroupId \
    FULL OUTER JOIN IPAM_GroupAttrData as D on C.GroupId = D.GroupId \
    WHERE IPAddress IN (%s);" % (Hosts_as_Tuples,)

print queryString

cur.execute(queryString)

Answer 2

感谢Adam和这里的SQL大师的咨询，我们设法证明％s的评估在mac和pc上似乎有所不同。

所以，我重新编写了如下代码（类似于Adam建议 - 但略有不同）：

try:
  sqlQuery = "SELECT * FROM dbo.IPAM_Node as A \
    FULL OUTER JOIN IPAM_NodeAttrData as B ON A.IPNodeId = B.IPNodeId \
    FULL OUTER JOIN IPAM_Group as C on A.SubnetId = C.GroupId \
    FULL OUTER JOIN IPAM_GroupAttrData as D on C.GroupId = D.GroupId \
    WHERE IPAddress IN " + str(Hosts_as_Tuples) + ";" 
  cur.execute(sqlQuery)

换句话说，我通过连接几个字符串来构建查询。这现在适用于Windows！

Pymssql程序适用于Mac，但不适用于Windows
