Hi all
In promoting SQLite 3 (still v3.2.7, so a bit behind the current
release) for a new project I have been doing some performance tests and
SQLite generally looks very good. However, I have seen one surprising
result.
My schema is simple, a single table with a simple autoincrement rowid as
the only index. Deleting all the rows from a table populated with
~600000 rows using simply DELETE FROM Foo takes twice as long as DELETE
FROM Foo WHERE 1. This is odd -
http://sqlite.org/capi3ref.html#sqlite3_changes - would lead me to
expect the opposite. So, I tried DROP TABLE Foo, and sure enough, the
time it takes is the same as the DELETE with no WHERE clause specified -
twice as long! Odd.
Any comments?
