I'm a little curious why D1 doesn't have a

.get()

.get()

.get()

.get() method to retrieve a single row in the db. Not that it's the end of the world that I have to do .all()[0] but it seems... weird, that I can't just do

db.prepare(blah).bind(somevar).get()

db.prepare(blah).bind(somevar).get()

db.prepare(blah).bind(somevar).get()

db.prepare(blah).bind(somevar).get() ?

<

<Alterion.Dev>•1/1/24, 4:52 PM

like,

const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).get();

// vs
const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).all()[0];

const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).get();

// vs
const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).all()[0];

const table = this.#db

Any way to create a DB if it doesn't already exist via CLI wrangler? I am scared of hitting the 2GB limit, so I need to create around 140 dbs to shard my data

Making a wow classic armory appliation via pages: https://atlasforge.gg/wow-classic/armory/us/crusader-strike/Rhyis and want to start storing basic data about characters in a D1 DB, so I can show level and item level leaderboards. I want to shard the data per wow server, and wow classic has 141 realms. Doing all that manually would be painful.

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

<Alterion.Dev>•1/1/24, 10:28 PM

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>•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)

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()

.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

K

kian•1/1/24, 10:37 PM

db.prepare(query).all()

db.prepare(query).all()

db.prepare(query).all()

db.prepare(query).all() is valid.

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

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>•1/1/24, 11:14 PM

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

<

<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.

W

WcaleNieWolny•1/3/24, 7:46 AM

What do you mean by batch my statements?

I use the http api and I do 1 call per row

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

So the first thing is that D1 doesn't support BEGIN TRANSACTION

I

Isaac McFadyen•1/3/24, 2:16 PM

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