Hi all
According to the documentation for the WITH clause, the recursive table
must appear exactly once in the FROM clause of the recursive-select and must
not appear anywhere else in either the initial-select or the
recursive-select, including subqueries.
I am trying to do the following -

WITH RECURSIVE temp AS (
[initial-select UNION ALL recursive-select]
)
SELECT * FROM temp UNION * FROM temp
Sorry, I meant
SELECT * FROM temp UNION SELECT * FROM temp

Could it be a version problem? I am using the version bundled with
Python3.4.1 for Windows.

Now I have to figure out how to get Python to use the upgraded version,

Hi all,
SQLite Database Browser v3.3.0 has been released. :)

That file name in the first error doesn't look like a vxWorks file. What
devices have you got mounted. You need to specify a file path that points to
one of the vxWorks file IO devices. By just specifying the file name in your
second example it is being created in the current directory.

Has anyone thought in some detail about what it would it take to add window

of graphs), SQLite with window functions would be immense.

Why are you checking two names against stop B, and none against stop A?
You also need to check that route A and route B actually connect - that
