Hello,
I would like to run the following update statement
if pragma user_version == 2.
How can I incorporate that in this query?
UPDATE pass_key
SET key = (SELECT textval FROM saved.pass_key b WHERE b.field='key')
WHERE name="KeyLock";
I've tried using CASE..WHEN..ELSE but it doesn't seem to
like the pragma statement in there.
You can access the user version using "PRAGMA user_version".
Unfortunately, you cannot combine a pragma with a larger query.
Could you add information_schema analogies to SQLite so that information like
what "pragma user_version" returns could then be accessed in arbitrary queries?
This probably wouldn't be too much work and would be a very powerful addition.
I'm not asking full information_schema support, but rather a representation of
SQLite metadata as tablevars. -- Darren Duncan
