Thanks to the help the other day with the strange concatentation result.
I was referring to a BF interpreter I was working on, in pure SQLite SQL.
Well, here it is, working.
Hopefully no-one finds this useful,

Evening
I'm seeing a weird effect when concatenting things:
WITH q(tape,dp) AS (SELECT '04E', 1)
SELECT SUBSTR(tape,1,dp-1) || SUBSTR(tape,dp,1)+1 || SUBSTR(tape,dp+1) AS
expect_14E,
SUBSTR(tape,1,dp-1) AS segment_1,
SUBSTR(tape,dp,1)+1 AS segment_2,
SUBSTR(tape,dp+1)
It's been a while since anyone has brought up PIVOT, and none that I
can see since table-valued functions were added [in 3.9.0, I think?]
Has anyone successfully implemented PIVOT using table-valued functions?
I'm in the situation again where I'd like a better way to pivot, where

ORDER BY val, DISTANCE(foo.x, foo.y, nearest.x, nearest.y,0)
LIMIT 1) AS id2

I posted a question on stackoverflow, here:
http://stackoverflow.com/questions/35382897/implementing-a-sql-query-without-window-functions
In short, I have a table that I'm trying to query:
CREATE TABLE foo (
id INTEGER PRIMARY KEY,
x REAL NOT NULL,
y REAL NOT NULL,
val REAL NOT NULL,
In the interests of itch-scratching, I've created a simple-ish tool to
render directed graphs from sqlite databases with foreign keys [using
graphviz]. I occasionally see people asking after such things in the
sqlite IRC channel.
It produces output like this:

Heya All,
I've been a long-time lurker on the irc channel, helping where I can.
One question that constantly pops up is "what's the sqlite equivalent of
mysql_real_escape_string?"
One doesn't like to necessarily answer that particular question as
posed, so up until now I've been explaining each t
