sql - 格式pandas.Timestamp用于SQLite查询

Question

from pandas.io import sql
import sqlalchemy

eng = sqlalchemy.create_engine('sqlite:////path/to/file.db')

In [20]: sql.execute("select * from mytable", eng).fetchone()
Out[20]: (0, u'2013-03-13 13:05:00.000000', 1, 0, 0, 0)

现在我该怎么做才能使它起作用：

target = Timestamp('2014-04-30')
sql.execute("select * from mytable where date = ?", eng, params=target).\
            fetchone()

Answer 1

str_format = '%Y-%m-%d %H:%M:%s'
target = Timestamp('2014-04-30').strftime(str_format)
