python - 无法使用 PyMySQL 插入日期

Question

插入语句如下所示:

INSERT INTO events(ts, domain, url, lat_lon, sha1_hash)
VALUES (STR_TO_DATE(%s, '%Y-%m-%dT%H:%i:%sZ'), %s, %s, %s, sha1(url))

当我尝试使用 executemany 发送批处理时，出现此错误:

Traceback (most recent call last):
  File "/vagrant/workspace/gdelt/gdelt_all.py", line 41, in <module> read_files()
  File "/vagrant/workspace/gdelt/gdelt_all.py", line 33, in read_files cursor.executemany(INSERT_FOUR, four)
  File "/usr/local/lib/python2.7/dist-packages/pymysql/cursors.py", line 195, in executemany self.rowcount = sum(self.execute(query, arg) for arg in args)
  File "/usr/local/lib/python2.7/dist-packages/pymysql/cursors.py", line 195, in <genexpr> self.rowcount = sum(self.execute(query, arg) for arg in args)
  File "/usr/local/lib/python2.7/dist-packages/pymysql/cursors.py", line 164, in execute query = self.mogrify(query, args)
  File "/usr/local/lib/python2.7/dist-packages/pymysql/cursors.py", line 143, in mogrify query = query % self._escape_args(args, conn)
ValueError: unsupported format character 'Y' (0x59) at index 83

我尝试转义 Y 以查看是否是正确的起点，但这没有帮助。有什么想法吗？

Escape %s 用于指定日期格式；这样它就不会被 Cursor.execute*(...)

处理

insert into events(ts, domain, url, lat_lon, sha1_hash) values 
(STR_TO_DATE(%s, '%%Y-%%m-%%dT%%H:%%i:%%sZ'), %s, %s, %s, sha1(url))
