Curtis Jones•10/9/23, 4:23 PM

I can confirm the same results you got with that test. However, a "real" query on my db that uses LIKE (with a 98 byte string) fails with that error while the GLOB equivalent succeeds. I'd very much like you to not fix this bug, so please disregard.

kianOP•10/9/23, 4:35 PM

I don’t think it’s a bug in D1 - D1 doesn’t enforce the limit itself, it just tells SQLite to do it. Maybe SQLite is optimising your pattern under the limit? I’m not sure.

kianOP•10/9/23, 4:35 PM

In any case, I wouldn’t consider it a bug.

David•10/9/23, 6:10 PM

Since today rows_written and rows_read is always 0 and the sql action wont get executed when running with "EXPLAIN QUERY PLAN". I have changed nothing in my code and it worked perfectly fine 2 days ago. Anyone else experiencing this?

Currently we are on mongodb and everyday we insert 20k rows to the db. On mongodb we insert them all together as a table and it parses it. How can we mass insert rows on D1 all together in order to avoid spaming 20k requests.

Hi, can we use this outside of workers? Since currently the db is managed by python code running in our servers.

No clue

afaik the only documented usage of D1 is through workers

when you reach your database memory limits, you'll start seeing errors from the api

Is it subject to the 1200/5 min limit of the API generally?

iirc there's a few APIs with their own limits - I guess if D1 ends up being popular enough to use outside of a Worker then that might be an option, but I suppose that might be directed to setting up your own API w/ a Worker

It should auto skip that prompt if detcted as CI or non-interactive. Are you seeing the prompt appear and thus CI fails or that when it applies migration there are no changes?

It’s an example: in practice, those values will be user provided and so you always want to use a parameterized query for security.

sorry，it might be cause by i didnt store the data correctly

kojo•10/9/23, 10:17 PM

heya, good folks of d1!

I'm currently building a project on cloudflare workers+pages+d1 that I'd like to be forkable. So the ideal workflow for the users is:

fork the repo of my deployed solution
set things up
run GitHub Action and get a URL

Now, for project without D1 I can at least theoretically imagine how the step 2 would look like. I. e. "create a cloudflare account, get token, paste token to GitHub Action Secrets". But with D1 I'm a bit stuck.

The reason I'm stuck is that the unique id of the database is in wrangler.toml and that the d1 is not even creatable in the dashboard until the first worker is deployed. So the user flow for setup becomes something like:
a. run deployment action with database turned off. It will deploy the worker that can't work because there's no database
b. go create a database in the dashboard
c. copy-paste the details of the database from dashboard to repo
d. deploy the solution again - this time with database enabled

Is there a better way? Am I missing something?

kianOP•10/9/23, 10:31 PM

It's not specific to D1, it's just your usual SQLite prepared statements. Executing a SQL statement requires compilation, so it's compiled and then held in memory for later re-use (all you have to do is bind new parameters rather than re-evaluate the entire query).

since I can't reproduce your issue, `GLOB` is limited to 50 bytes as documented for me
