Question

我是Python新手，我试图循环非常大的CSV文件（4 GB）并将其放入MSSQL服务器。当前的SQL工具似乎没有帮助！

附件是我的剧本。我在运行它时遇到错误。任何帮助，将不胜感激。

MSSQL数据库退出。登录和密码是正确的。我还为windows安装了pymssql模块

E：\ Python27＆gt; python -x parsedata_mssql.py Traceback（最近一次调用最后一次）：文件“parsedata_mssql.py”，第28行，in 除了mdb.Error，e： NameError：名称'mdb'未定义

以下是我的代码：

           #! /usr/bin/python

          import csv
          import sys
          import _mssql

          fields = [
          (0, 'name'),
          (1, 'street'),
          (2, 'city'),
          (3, 'state'),
          (4, 'zip'),
          (5, 'u1'),
          (6, 'u2'),
          (7, 'phone1'),
          (8, 'phone2'),
          (9, 'contactname'),
          (10, 'relationship'),
          (11, 'gender'),
          (12, 'u3'),
          (13, 'u4'),
          (14, 'industry'),
  ]

         try:
dbconn = _mssql.connect(server='localhost\SQLEXPRESS', user='sa',
        password='password', database='2007usdata')
        except mdb.Error, e:
           print "Error %d: %s" % (e.args[0], e.args[1])
          sys.exit(1)

   with open('2007usdata.csv', 'rb') as infile:
reader = csv.reader(infile)
count = 0
for line in reader:
    print "\n\nProcessing\n"
    print line
    if line:
        column_names = ','.join([name for (id, name) in fields])
        value_placeholders = (len(fields) - 1) * '%s, ' + '%s'
        query = "INSERT INTO info(%s) VALUES(%s)" % (column_names, value_placeholders)
        try:
            dbconn.execute_non_query(query, line)
            count += 1
            dbconn.commit()
        except mdb.Error, e:
            print "Error %d: %s" % (e.args[0], e.args[1])
            sys.exit(1)
   dbconn.close()

   print "\n\nDone: processed %d lines" % (count)

运行python脚本以将CSV提取到mssql的MDB错误
