I found the answer: using "RETURNING rowId" at the end of the statement did the job.

I have a couple of questions about migrations. Do they run automatically locally, or remotely? Or do you always run them with the command? And second, is there any way to specify which migrations go to which database? It looks like you create them with a database name, but then any database will list them as a migration for it. Is that an oversight?

There is not yet a #d1-feature-suggestions but I would like to suggest somes features:

G

GuillaumeLakano•10/26/23, 8:50 AM

1) To permit in a batch requests list to have a way to continue or stop the batch, based on the previous result. This will prevent multiple roundtrips between the Workers <=> D1, for example you want to execute some requests but first, you need to be sure the session of this user is still alive and also want to update the session:

await db.batch([
    db.prepare('UPDATE sessions SET updated=CURRENT_TIMESTAMP WHERE id_session=?1')
        .bind(session)
        .expect({ meta: { changes: 1 } }),
    db.prepare('SELECT * FROM ...'),
    ...
])

await db.batch([
    db.prepare('UPDATE sessions SET updated=CURRENT_TIMESTAMP WHERE id_session=?1')
        .bind(session)
        .expect({ meta: { changes: 1 } }),
    db.prepare('SELECT * FROM ...'),
    ...
])

await db.batch([
    db.prepare('UPDATE sessions SET updated=CURRENT_TIMESTAMP WHERE id_session=?1')
        .bind(session)
        .expect({ meta: { changes: 1 } }),
    db.prepare('SELECT * FROM ...'),
    ...
])

await db.batch([
    db.prepare('UPDATE sessions SET updated=CURRENT_TIMESTAMP WHERE id_session=?1')
        .bind(session)
        .expect({ meta: { changes: 1 } }),
    db.prepare('SELECT * FROM ...'),
    ...
])

G

GuillaumeLakano•10/26/23, 8:50 AM

2) An extension of this idea, still to prevent roundtrips, is to catch a value from a previous result and to uses it in another request of the batch. Imagine the client/browser never known his own id_user, only the session ID, but the id_user is stored in a field of the sesssion table, then you could optimise your roundtrips like this:

await db.batch([
    db.prepare('UPDATE sessions SET updated=CURRENT_TIMESTAMP WHERE id_session=?1 RETURNING *')
        .bind(session)
        .expect({ meta: { changes: 1 } })
        .set({ user: 'id_user' }), // Or user: [ 'id_user', 0 ] to indicate a position in the results array
        
    db.prepare('SELECT * FROM users WHERE id_user=?1').bind( db.get('user') )
    ...
])

await db.batch([
    db.prepare('UPDATE sessions SET updated=CURRENT_TIMESTAMP WHERE id_session=?1 RETURNING *')
        .bind(session)
        .expect({ meta: { changes: 1 } })
        .set({ user: 'id_user' }), // Or user: [ 'id_user', 0 ] to indicate a position in the results array
        
    db.prepare('SELECT * FROM users WHERE id_user=?1').bind( db.get('user') )
    ...
])

await db.batch([
    db.prepare('UPDATE sessions SET updated=CURRENT_TIMESTAMP WHERE id_session=?1 RETURNING *')
        .bind(session)
        .expect({ meta: { changes: 1 } })
        .set({ user: 'id_user' }), // Or user: [ 'id_user', 0 ] to indicate a position in the results array
        
    db.prepare('SELECT * FROM users WHERE id_user=?1').bind( db.get('user') )
    ...
])

await db.batch([
    db.prepare('UPDATE sessions SET updated=CURRENT_TIMESTAMP WHERE id_session=?1 RETURNING *')
        .bind(session)
        .expect({ meta: { changes: 1 } })
        .set({ user: 'id_user' }), // Or user: [ 'id_user', 0 ] to indicate a position in the results array
        
    db.prepare('SELECT * FROM users WHERE id_user=?1').bind( db.get('user') )
    ...
])

3) It's not really a feature, but activate the SQLite configuration flag SQLITE_ENABLE_UPDATE_DELETE_LIMIT to permit to uses LIMIT on INSERT/UPDATE/DELETE, could also permit us to optimise some requests and to add a layer of security.

D1 feature request: Some option for Unicode collation (specifically non-ASCII case insensitivity)

Could we have the ICU extension enabled?, see https://sqlite.org/src/dir/ext/icu
Sadly, this could affect existing indexes (as discussed at the bottom of the link).
So, another potential option is to implement a custom collation sequence (via create_collation - https://www.sqlite.org/c3ref/create_collation.html ). For example, add a new 'UNICODE_NOCASE' collation that could then be used on columns or specific where clauses with

... COLLATE UNICODE_NOCASE

... COLLATE UNICODE_NOCASE

... COLLATE UNICODE_NOCASE

... COLLATE UNICODE_NOCASE.

I'm currently adding duplicate columns with the data passed through Javascript's toLower(), but that's a PITA.
I understand it is ultimately an Sqlite quirk. However, Sqlite provides the above two options, but consumers of D1 have no control of those extensions/APIs which is why some assistance from D1 would be helpful.

Stanislav Trofimchuk wrote a really good background piece, with lots of discussion and example showing use of custom collation (from Python): https://shallowdepth.online/posts/2022/01/5-ways-to-implement-case-insensitive-search-in-sqlite-with-full-unicode-support/ and a great follow up post specifically on performance: https://shallowdepth.online/posts/2022/01/performance-of-application-defined-functions-and-collations-in-sqlite/

I second this, internationalized case insensitivity would be useful, instead of keeping a second column where all characters are ascii-mapped in advance so case doesn't matter
