Question

我正在解析XML并尝试将其值插入mysql数据库。（我只从typename开始）

XML看起来像：

<collection shelf="New Arrivals">
<movie title="Enemy Behind">
   <type>War, Thriller</type>
   <format>DVD</format>
   <year>2003</year>
   <rating>PG</rating>
   <stars>10</stars>
   <description>Talk about a US-Japan war</description>
</movie>
<movie title="Transformers">
   <type>Anime, Science Fiction</type>
   <format>DVD</format>
   <year>1989</year>
   <rating>R</rating>
   <stars>8</stars>
   <description>A schientific fiction</description>
</movie>
   <movie title="Trigun">
   <type>Anime, Action</type>
   <format>DVD</format>
   <episodes>4</episodes>
   <rating>PG</rating>
   <stars>10</stars>
   <description>Vash the Stampede!</description>
</movie>
<movie title="Ishtar">
   <type>Comedy</type>
   <format>VHS</format>
   <rating>PG</rating>
   <stars>2</stars>
   <description>Viewable boredom</description>
</movie>
</collection>

我的代码如下：

# Print detail of each movie.
for movie in movies:
    print ("*****Movie*****")
    if movie.hasAttribute("title"):
        print ("Title: %s" % movie.getAttribute("title"))
        titleName = movie.getAttribute("title")
        with con:
            cur = con.cursor()
            cur.execute("INSERT INTO Writers(Name) VALUES('Enemy Behind')")
    type = movie.getElementsByTagName('type')[0]
    print ("Type: %s" % type.childNodes[0].data)
    with con:
        typeName = type.childNodes[0].data
        cur=con.cursor()
        cur.execute("INSERT INTO Writers(type) VALUES(typeName)")
    format = movie.getElementsByTagName('format')[0]
    print ("Format: %s" % format.childNodes[0].data)
    rating = movie.getElementsByTagName('rating')[0]
    print ("Rating: %s" % rating.childNodes[0].data)
    description = movie.getElementsByTagName('description')[0]
    print ("Description: %s" % description.childNodes[0].data)

我得到错误：

Title: Enemy Behind
Traceback (most recent call last):
  File "C:/....MyPython.py", line 35, in <module>
    cur.execute("INSERT INTO Writers(type) VALUES(typeName)")
  File "C:\Python34\lib\site-packages\MySQLdb\cursors.py", line 220, in execute
Type: War, Thriller

是否有人可以帮助我找出问题所在？我完全是新手，所以我完全迷失了

Answer 1

# Closing the redirected text files. sys.stdout.close() sys.stderr.close() # Defining the paths for the temp folder and the existing text files. folder = args.directory + "\\" + "temp" stdoutPath = folder + "\\" + "stdout.txt" stderrPath = folder + "\\" + "stderr.txt" # Deleting the text files first, then deleting the entire temporary folder. os.remove(stdoutPath) os.remove(stderrPath) os.rmdir(folder)类型中有一个空格。尝试将此行更改为 War, Thriller到cur.execute("INSERT INTO Writers(type) VALUES(typeName)")要在查询中包含cur.execute("INSERT INTO Writers(type) VALUES('typeName')")以包含typeName。

示例

^{假设类型为''，char等}

此SQL varchar将失败，因为我们插入的字符串值未用引号括起来。

然而， insert into Writers(type) values(my string)应该有效，因为我们用引号括起了我们插入的字符串值。
