Stéphane Wirtel <steph...@wirtel.be> added the comment: For my part, we could close this issue just because I am sure they sniff the format of the string. If you use sqliteman you get a TEXT and not "datetime"
You can read this doc about the read_sql https://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_sql.html Now, sqlite3 does not support the datetime type and I think it is not the job of Python to do this operation but the caller (your code) but you can see the example in Doc/includes/sqlite3/pysqlite_datetime.py ```python import sqlite3 import datetime con = sqlite3.connect(":memory:", detect_types=sqlite3.PARSE_DECLTYPES|sqlite3.PARSE_COLNAMES) cur = con.cursor() cur.execute("create table test(d date, ts timestamp)") today = datetime.date.today() now = datetime.datetime.now() cur.execute("insert into test(d, ts) values (?, ?)", (today, now)) cur.execute("select d, ts from test") row = cur.fetchone() print(today, "=>", row[0], type(row[0])) print(now, "=>", row[1], type(row[1])) cur.execute('select current_date as "d [date]", current_timestamp as "ts [timestamp]"') row = cur.fetchone() print("current_date", row[0], type(row[0])) print("current_timestamp", row[1], type(row[1])) ``` ```shell 2018-11-04 => 2018-11-04 <class 'datetime.date'> 2018-11-04 12:58:01.399669 => 2018-11-04 12:58:01.399669 <class 'datetime.datetime'> current_date 2018-11-04 <class 'datetime.date'> current_timestamp 2018-11-04 11:58:01 <class 'datetime.datetime'> ``` ---------- nosy: +matrixise resolution: -> fixed stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35145> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
