Select time from today
I am struggeling with a SQLite query.
I have the following table in my database:
CREATE TABLE "timings" ( `id` integer PRIMARY KEY AUTOINCREMENT, `time` text NOT NULL, `timestamp` INTEGER )
Now, I want to read the entry with the lowest time from a day.
In the attached picture, I want to read row with id = 3
I have tried different querys for example:
SELECT DISTINCT time FROM timings
SELECT time, MAX(timestamp) FROM timings WHERE time > '21.11.2018 00:00:00'
but my WHERE is anyhow wrong.
Maybe has someone an idea?

Did you tried SELECT MIN(time) FROM timings

yes, I tried also MIN() time and MAX() time. Unfortunately, SELECT MIN(time) FROM timings return the oldest entry. It could happen, that the entry is not the latest and not the first.

No, SQLite is not supporting DateTime format.

Use this SELECT TOP 1 * from timings ORDER BY time DESC

I have solved the issue.
I decided to delete all entries they are not from today:
"DELETE FROM timings WHERE time < '" + yesterDay.ToString() + "'";
Then I can be sure, that only entries from today are in the SQlite database.
After that I do the following:
Select MIN(timestamp) FROM timings
This will return my oldest value.
Thanks for your support ;)
