You might have called it

env.DB

env.DB

env.DB

env.DB somewhere but your wrangler binding is for

env.TEMPDB

env.TEMPDB

env.TEMPDB

env.TEMPDB - you'll want to update the code

Nehal AliOP•9/6/23, 1:05 PM

i pass env.TEMPDB to my templates model constructer and then use this.DB.prepare(...)

i am getting an error "env.DB.prepare(...).run is not a function" , i logged env.DB and it is undefined,

Right —

env.DB

env.DB

env.DB

env.DB is undefined because you called it

TEMPDB

TEMPDB

TEMPDB

TEMPDB. How do you get from the D1 binding on

env.TEMPDB

env.TEMPDB

env.TEMPDB

env.TEMPDB to your own class?

Can I suggest simplifying your code here? Call the methods on

env.TEMPDB

env.TEMPDB

env.TEMPDB

env.TEMPDB directly vs. abstracting them - get it working first.

This works in local dev, and my other CRUD routes work without issue, however the following code throws error

Error: D1_ERROR: Error: not authorized

Error: D1_ERROR: Error: not authorized

Error: D1_ERROR: Error: not authorized

Error: D1_ERROR: Error: not authorized in production.

Anybody have any ideas? Is something not supported in D1 like

returning()

returning()

returning()

returning() or transactions or something? I'm using Miniflare in dev and it works there.

(using Drizzle ORM)

        const newTeam = await locals.db
            .transaction(async (tx) => {
                const newTeam = await tx.insert(teams).values(form.data).returning().get();

                return newTeam;

hey guys I have almost per monthly KV write operations around 5 million, and it is costing me almost 30$ + a month, My question is the D1 database in open alpha right now, can I use it in my service to replace KV for some operations, Like I am storing users IP address currently in KV , it can handle millions read and write?

Baby goo-goo-ga-ga question if I want to create a table with a key that is an array or strings, is that possible / what is the syntax?

    'fields_of_study' Array of Text?
);

I don't think there's any native support for arrays, but you could store it as a JSON array & query it as such - https://developers.cloudflare.com/d1/learning/querying-json/

Query JSON · Cloudflare D1 docs

D1 has built-in support for querying and parsing JSON data stored within a database. This enables you to:

Ok so I'm unsure if I'm understanding this documentation correctly, but it seems there are

json

json

json helper functions for use with your SQL queries i.e.

SELECT * ...

SELECT * ...

SELECT * ...

SELECT * ... or

db.prepare("SELECT * ...

db.prepare("SELECT * ...

db.prepare("SELECT * ...

db.prepare("SELECT * ...

I'm just trying to understand how to put it into practice -
I have

const data = db.prepare("SELECT * FROM profiles WHERE user_id = ?").bind(id).first()`

const data = db.prepare("SELECT * FROM profiles WHERE user_id = ?").bind(id).first()`

const data = db.prepare("SELECT * FROM profiles WHERE user_id = ?").bind(id).first()`

const data = db.prepare("SELECT * FROM profiles WHERE user_id = ?").bind(id).first()`

This data is already just about what I want, except my

fields_of_study

fields_of_study

fields_of_study

fields_of_study key is the string

"['Major 1', 'Major 2']"

"['Major 1', 'Major 2']"

"['Major 1', 'Major 2']"

"['Major 1', 'Major 2']".

Am I storing the data incorrectly in the column or do I need to restructure my query so that D1 will parse the array into a javascript object?

What's the question, though? The return value?

itsmatteomanf•9/8/23, 8:43 PM

The JSON helper functions help for traversing or fetching specific parts of a JSON object stored in a column.

I

itsmatteomanf•9/8/23, 8:43 PM

They run at the SQL query level, not in the Worker.

S

slowpoke•9/8/23, 8:44 PM

I just thought though, I think I could always just do JSON.parse() on the key before returning it to the client

I

itsmatteomanf•9/8/23, 8:44 PM

Yeah, you can lul

slowpoke•9/8/23, 8:44 PM

I think I thought that this was used to also parse JSON strings without needing the use of parse. Lmao

S

slowpoke•9/8/23, 8:45 PM

I see what you mean. This will help you traverse your JSON strings in a column without needing to like… do everything that entails to update one object key.
