python - 如何在python中执行sql时使用字符串

Question

在我的 Cur4.execute 中，我尝试将艺术家姓名与我之前从 cur3 获得的艺术家姓名进行比较 (name = row[1])， 但我得到了错误:

Traceback (most recent call last):
  File "mp2.py", line 49, in <module>
    cur4.execute('SELECT * FROM artist WHERE artist.name = %s',name)
  File "C:\python27\lib\site-packages\MySQLdb\cursors.py", line 187, in execute
    query = query % tuple([db.literal(item) for item in args])
TypeError: not all arguments converted during string formatting

我该如何解决这个问题？

cur3 = db.cursor()
cur3.execute("SELECT image.link, artist.name, detail.detail_id, FROM artist, detail, image WHERE image.artist_id = artist.artist_id AND detail.image_id = image.image_id LIMIT 1")
ans = cur3.fetchall()
for row in ans:
    print row[1:]   
    name = row[1]
db.close()

cur4 = db.cursor()
cur4.execute('SELECT * FROM artist WHERE artist.name = %s',name)

Answer 1

我不是专家，但也许可以尝试用括号将字符串格式区域括起来，而不是 cur4.execute('SELECT * FROM Artist WHERE Artist.name = %s',name)得到这个:

cur4.execute(('从艺术家中选择* WHERE艺术家.name = %s',name))

编辑:实际上，我认为 mshsayem 是对的(原始问题的评论)
