I would like to implement this:
If exist
update
Else
insert
It seems that I am touching the database two times. Is there any shorter way to implement this in sqlite3?

If you have a unique constraint on the key field, you could use the INSERT OR REPLACE
command which automatically deletes the old record if the new one would create a duplicate.
However, this does not give you a performance advantage: There must always be some check for the record; whether you are doing an explicit SELECT
or are using SQLite's built-in duplicate detection does not make much of a difference.
