SHi team, can we use SQLite triggers in d1?
SMy usecase is as follows:
S
-- Create a table. And an external content fts5 table to index it.
CREATE TABLE tbl(a INTEGER PRIMARY KEY, b, c);
CREATE VIRTUAL TABLE fts_idx USING fts5(b, c, content='tbl', content_rowid='a');
-- Triggers to keep the FTS index up to date.
CREATE TRIGGER tbl_ai AFTER INSERT ON tbl BEGIN
INSERT INTO fts_idx(rowid, b, c) VALUES (new.a, new.b, new.c);
END;
CREATE TRIGGER tbl_ad AFTER DELETE ON tbl BEGIN
INSERT INTO fts_idx(fts_idx, rowid, b, c) VALUES('delete', old.a, old.b, old.c);
END;
CREATE TRIGGER tbl_au AFTER UPDATE ON tbl BEGIN
INSERT INTO fts_idx(fts_idx, rowid, b, c) VALUES('delete', old.a, old.b, old.c);
INSERT INTO fts_idx(rowid, b, c) VALUES (new.a, new.b, new.c);
END;
SBasically using triggers to keep the fts5 virtual table indexes in sync with a content table, is this possible?
MI currently use triggers in D1. So yes.

《Hey has anyone come across a bug when attempting to execute a
I can execute the same script with no issue via DBeaver, but when attempting to do it via wrangler 3.20 and wrangler 2.20 I get this no such table error?
DROP TABLE IF EXISTS [table001]no such table: main.[table001]?I can execute the same script with no issue via DBeaver, but when attempting to do it via wrangler 3.20 and wrangler 2.20 I get this no such table error?
《I have been using brackets, and it didn't seem to cause an issue for me.
《The brakets here are just an example, I don't have that in the code.
《here is a better example, I'm just being careful not to share IP that is not my own.
《Okay, I'll attempt to change all my square brackets to be '`'
The thing is, it doesn't even seem to get past the initial DROP IF EXISTS statement shown above, and that has not brackets around it.
Probably should just ignore that original example I gave, and look at the screenshots.

Yeah, It has to be something in the script. I've been rebuilding this for a while, and not had this issue in the past @Matt
What throws me off is the script works and rebuilds fine form DBeaver. So smells like a support thing.

《Yes that works as well. Lists out the tables in there.
《Hmmm I have created a sub set of the scripts that I'm working with.
I have a list of all the DROP TABLE IF EXISTS,
and a sub set of CREATE table x4.
and I'm seeing the no such table error again.
I assume this is the correct command to see locally?
Because when I check the table_list, it seems like nothing changed.

MYes,
--local--localwrangler d1 execute [...]- it runs on the Cloudflare network or "production" to some. If you haven't created that table in prod == you get errors.
《okay cool. So everything I'm doing right now is --local. I do have a production and develop database in the network, and have previously used this method to update them with no issue.
《I did attempt to run ths same script against my development database, and wittnessed the same error I'm getting locally.
《SO at least it's consistent...
MNote that if you're using DBeaver: I don't think it supports D1. Local SQLite != D1. I have a suspicion some of your issues are distinct from D1 itself.
《Right, so the sqlite3 files was originally created with wrangler, but I have been editing it locally using DBeaver, by pointing the connection to ./.wrangler/state/d1/...
So you think DBeaver might have currupted the sqlite3 file in some way? Because yeah, I was just writing a list of things I tried, and there is some odd stuff happening.

《What IDE would you recommend?
《I do have Views, and triggers in this DB too.. I'm assuming that fine, because it all seems to be working.
《So with that train of thought. I removed DBeaver from the process. I delete the local database, and rebuilt it using the same script locally using wrangler only.
Then tried to run the database build script a 2nd time using just wrangler and got the same no such table error.
If I manually drop the tables in the same order as the script attempts, with no 'If Exists' then it works.
If I try to drop the tables in the same order with If Exists is shows the error.
So not sure if that makes sense, but yeah. I wouldn't expect to see that error.

LHi Matt, yes I am using the original backend since it has back-ups enabled. Is there a migration path planned from the original backend to the experimental backend when backups become available on the experimental as well?
《@Matt Anyway I'll leave this and come back to it tomorrow. Thanks for the help so far. I'll prob come back tomorrow with a solution hopefully. Thanks again
MNot an automated path in the near term (primarily because these are alpha databases, not production databases). You can easily export and then run
execute DB_NAME --file=export.sqlI'd suggest opening an issue on GitHub — I think we have exhausted debugging here via Discord without seeing your SQL. I really suspect your migration/seed scripts are just not creating the right tables first.
LThis will sound really dumb but, how do I export my database using Wrangler?
LThanks nora!
Just FYI, in case someone else runs into a problem that I ran into during the process:
On windows, after converting the backup to a sql file using sqlite3 (using sqlite3 <path-to-downloaded-file> .dump > latest.sql) when attempting to import via npx wrangler d1 execute <name> --file=latest.sql, wrangler was complaining about an imaginary synthax error like this:
near "��P": syntax error [code: 7500]".
It turns out this is an encoding problem, the sql file ended up encoded in UTF-8-BOM and had to be converted to UTF-8. You can do this using Notepad++ via the Encoding menu option and then saving. After which, the import worked flawlessly (18MB database imported in about 30 seconds or so)

LIs there a rough estimate regarding enabling backups on the experimental backend?
This backend is significantly faster, event without indexes, but I am reluctant to using it until I have backups running.
