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

Rabid•1/1/24, 8:08 PM

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.

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

<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

kianOP•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!

<

<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>•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

Is it possible to get D1 query metrics via a wrangler or dashboard query?

R

Rabid•1/2/24, 1:35 PM

Running

npx wrangler d1 execute wow-classic-us-seasonal --command "SELECT * FROM characters ORDER BY pvp_rank DESC LIMIT 5"

npx wrangler d1 execute wow-classic-us-seasonal --command "SELECT * FROM characters ORDER BY pvp_rank DESC LIMIT 5"

npx wrangler d1 execute wow-classic-us-seasonal --command "SELECT * FROM characters ORDER BY pvp_rank DESC LIMIT 5"

Matt Silverlock•1/3/24, 6:38 AM

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?

WcaleNieWolny•1/3/24, 7:47 AM

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

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.

WcaleNieWolny•1/3/24, 2:17 PM

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

WcaleNieWolny•1/3/24, 2:18 PM

how would you like me to send a batch statement using this http api?

right - so it also does not support the batch api

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 test

npx wrangler d1 create test

npx wrangler d1 create test

npx wrangler d1 create test

results in

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

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

[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"

[[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 login

npx wrangler login

npx wrangler login

npx wrangler login again. Odd because it was still letting me deploy. A better error message would have been helpful.
