Watch not working with IN and ANY Query. #258

So I think this boils down to the query not being valid (it might be valid for Postgres which supports some additional syntax that SQLite does not, which is why you can run it when managing the instance).
var stream = db.watch(
'SELECT * FROM events WHERE creator_user = ?1 OR ?1 IN (SELECT value FROM json_each(manager_ids)) ORDER BY start_date ASC', parameters: [FFAppState().user.userId]);
eventsSubscription = stream.listen((data) {
callback(data.map((json) => EventsRow(Map<String, dynamic>.from(json))).toList());
});
That's something we should take a look at (I would the query to report an error), thanks! I think the stream you're listening to should emit an error event, and since you don't have an |

Hi @simolus3, Apologies, but none of the suggested solutions have worked for me. After applying the json_each query, it works successfully in the PowerSync Diagnostics tool but does not trigger updates in the Flutter app.
I have attached screenshots for better clarity. Please take a look and let me know if there's a possible fix.

So at least we know that there is an error getting logged after all :)

Yes, the declaration resolved the crash issue, but the data is still not loading. Please check the attachment—I declared it as follows, but I can't find the integer array in the schema: I can retrieve only exact matches, but queries using IN are not working. |

I'm syncing data from Supabase Postgres. The same query executes correctly in the console and even appears correctly in diagnostics, but in the app, it only returns results for exact matches (=) and does not work with IN. |
Is that still true after changing To help us understand what's causing us to miss the type here, could you please run the following query in the PowerSync dashboard and share the results (I know it's quite long, that's the query we use internally to figure out types, I've changed it so that it only reports the single row for the SELECT

@simolus3 Thanks for your kind support! Please find the following requested details by executed your query in powersync dashboard.
And the following way, I have added in flutter code Let me know if needed to refactor any. |

Thanks for posting the results, we're looking into this!
I think that should be everything. Does the query work now that you've changed the type here? |
I am using PowerSync in my Flutter app, and I need to listen for real-time updates in my local database. However,
db.watchis not triggering updates when changes occur in the synced tables.Code Implementation
This is how I'm using db.watch in my app:
The query works as expected in the PowerSync console but does not work inside the Flutter app.
Even when testing via the PowerSync diagnostics platform, the query does not return results.
There issue in IN and ANY Query.
Screenshots
The following screenshots illustrate the issue:
I have verified that the table is updating correctly by running sync rules.
No errors or exceptions appear in the logs related to db.watch.
Manually querying the database reflects expected changes, but the listener does not trigger.
Would appreciate any guidance on resolving this issue. Thanks in advance! 🚀
