这个错误一般是由于更新时没有找到符合预期的行导致的。这可能是由于在更新之前，已经有其他的会话或事务更新了相同的行，导致当前的更新未能找到预期的行。你可以检查一下，是否有其他的操作在同时修改这个表中的数据。此外，你也可以尝试使用乐观锁或悲观锁来避免这种错误。如果你需要更具体的解决方案，可以提供更多的上下文信息。

我要用python读取{"reviewerID": "A11N155CW1UV02", "asin": "B000H00VBQ", "reviewerName": "AdrianaM", "helpful": [0, 0], "reviewText": "I had big expectations because I love English TV, in particular Investigative and detective stuff but this guy is really boring. It didn't appeal to me at all.", "overall": 2.0, "summary": "A little bit boring for me", "unixReviewTime": 1399075200, "reviewTime": "05 3, 2014"}中的reviewText

要使用Python读取给定的JSON字符串中的`reviewText`，您可以使用`json`模块解析JSON数据并获取所需的值。下面是一个示例代码：

import json

json_data = '{"reviewerID": "A11N155CW1UV02", "asin": "B000H00VBQ", "reviewerName": "AdrianaM", "helpful": [0, 0], "reviewText": "I had big expectations because I love English TV, in particular Investigative and detective stuff but this guy is really boring. It didn\'t appeal to me at all.", "overall": 2.0, "summary": "A little bit boring for me", "unixReviewTime": 1399075200, "reviewTime": "05 3, 2014"}'

# 解析JSON数据
data = json.loads(json_data)

# 获取reviewText的值
review_text = data['reviewText']

print(review_text)

运行此代码将输出：

I had big expectations because I love English TV, in particular Investigative and detective stuff but this guy is really boring. It didn't appeal to me at all.

这样，您就可以成功读取JSON数据中的`reviewText`值了。希望对您有所帮助！如果您有任何其他问题，请随时提问。
