Hi Roger,
I just downloaded SQLite3 version 3.6.19 and did the same testing as I
did before:
CREATE TABLE Simple (ID integer primary key, Name text);
CREATE VIRTUAL TABLE SimpleFTS USING FTS3 (Name);
CREATE TRIGGER DeleteTrigger AFTER DELETE ON Simple FOR EACH ROW BEGIN
DELETE FROM SimpleFTS
Consider the two statements below.
A: SELECT COUNT(DataID) FROM Data GROUP BY DataID ORDER BY COUNT(DataID);
B: SELECT COUNT(DataID) AS X FROM Data GROUP BY DataID ORDER BY X;
Is statement B faster than A? Why?

Ah - yes of course, I left it out here, since it currently is "win only"

Last time I checked, SQLite didn't perform any kind of common subexpression

Sure I can test this specific case, but my question is still relevant. Does
SQLite or does it not optimize repeated expressions?
Am I supposed to brute-force all possible expression repetitions to find it
out, when a simple "yes" or "no" from anybody - who knows about the inner
workings of

You are correct. Stated as above, your question is very valid

The underlying cause is that FTS3 has several other tables (use .dump to see
them) that store its
