The file that I use ".import" on contains records like this:
'2018-03-22 07:01:01'|2533268 I had assumed the value was being treated as a datetime, but it looks like it may be treated as a string? Im a bit confused because the column definition sais "datetime", not "varchar", so if it's being treated as a string what can I do to fix it to be treated as a actual datetime datatype? -----Original Message----- From: sqlite-users [mailto:sqlite-users-boun...@mailinglists.sqlite.org] On Behalf Of Peter Da Silva Sent: Thursday, March 22, 2018 6:49 AM To: SQLite mailing list Subject: Re: [sqlite] How to convert a datetime column to a date? 1. It looks like you have superfluous quotes around the dates. That's probably your issue. 2.

I tried this “top 10” but it’s apparently not supported. -----Original Message----- From: sqlite-users [ <mailto:sqlite-users-boun...@mailinglists.sqlite.org> mailto:sqlite-users-boun...@mailinglists.sqlite.org] On Behalf Of Peter Da Silva Sent: Thursday, March 22, 2018 6:33 AM To: SQLite mailing list Subject: Re: [sqlite] How to convert a datetime column to a date?
