Hmm that part I'm not sure of as I don't use Pages functions... there is a PATCH REST API to alter worker bindings, maybe similar exists for pages?

You can use the REST API to both create the D1 databases and bind them to a pages project

That's... interesting. am I just used to all the other libraries just using .get() ? Any specific technical reason this is different here, along with the .bind() being required?

<Alterion.Dev>

<

<Alterion.Dev>•1/1/24, 10:32 PM

no I mean, you need to do db.prepare(query).bind(params).all() , for example. But other sqlite modules basically all do

db.prepare(query).all(params)

db.prepare(query).all(params)

.

<Alterion.Dev>•1/1/24, 10:33 PM

The fact that it's

.first()

.first()

instead of

.get()

.get()

is a separate "why would this be different" issue. Like, I don't want to sound rude, it just feels like there's no legitimate reason for these things to not use a more standardised sqlite API

db.prepare(query).all()

is valid.

I will certainly not argue that returning the first column of a result is wrong - absolutely not!

<Alterion.Dev>•1/1/24, 11:13 PM

My question is why doesn't D1 follow the known convention of all the other npm sqlite wrappers that I know of, essentially

<Alterion.Dev>

<

<Alterion.Dev>•1/1/24, 11:14 PM

having first() and get() would make this easier to move existing code to D1

<Alterion.Dev>

<

<Alterion.Dev>•1/1/24, 11:15 PM

And removing .bind() intermediary in order to directly support binding in the execution call (run(), all(), get(), exec()) would also make it a lot easier

How are you attempting to migrate? You should batch your inserts - there’s no reason you can’t insert 10k+ rows per statement, or more, depending on overall width.

Pass multiple statements in one API call, separated by a semicolon. You’re being rate limited by the HTTP API, not D1 itself.

Any statements sent as part of the batch API are automatically executed in a transaction, but otherwise transactions are handled by D1 internally.

right - I only have https://developers.cloudflare.com/api/operations/cloudflare-d1-query-database available - will this work as batch there?

Sorry, I interpreted that you had a Worker, or were using wrangler to execute a file export. Row by row in the HTTP API has this limitation (for now)

Trying to setup a d1 database on the remote worker with the following command:

npx wrangler d1 create testnpx wrangler d1 create test

results in

[ERROR] Cannot read properties of undefined (reading 'map')[ERROR] Cannot read properties of undefined (reading 'map')

Using the --local flag works however.

In my wrangler.tml I have:

[[d1_databases]]
binding = "DB"
database_name = "name-of-db"
database_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

[[d1_databases]]
binding = "DB"
database_name = "name-of-db"
database_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

What am I doing wrong?

EDIT:
Oops. Turned out I'd been signed out of cloudflare and I needed to run npx wrangler loginnpx wrangler login again. Odd because it was still letting me deploy. A better error message would have been helpful.

It would be a big QOL change to handle pagination of D1 databases in the UI better. So when you click on a db, and go back, you don’t have to navigate to the page you were on again. Right now the URL is unchanged when paging through DBs or DB rows.
