如何从 python 中的 mysql 查询中转义 %.
How do I escape the % from a mysql query in python.
例如
query = """SELECT DATE_FORMAT(date_time,'%Y-%m') AS dd
FROM some_table
WHERE some_col = %s
AND other_col = %s;"""
cur.execute(query, (pram1, pram2))
给我一个ValueError: unsupported format character 'Y'"异常.

推荐答案
文档:
请注意，传递给 execute() 的查询字符串中的任何文字百分号都必须进行转义，即 %%.
Note that any literal percent signs in the query string passed to
execute()must be escaped, i.e.%%.
