Are you trying to access internal SQLite tables or use SQLite pragmas?

I

Isaac McFadyen•8/15/24, 5:27 PM

Some are blocked on D1 for security reasons.

I

Isaac McFadyen•8/15/24, 5:28 PM

If you are using a database ORM or explorer then it's possible it's making those queries on your behalf to try and inspect the schema of the database (and getting blocked).

When importing data into a D1 db using the wrangler command it mentions: "This process may take some time, during which your D1 database will be unavailable to serve queries.". I noticed this also in a test as drizzle showed "7500: Currently processing a long-running import." on a select query. Is there any way to get around this? Lets assume that the DB is already being used in production, I would like for the app to continue working. Any suggestions?

Hello all! I need to rename a few columns in the existing table. For some reason, the RENAME statement doesn't work for me. Does d1 support the RENAME statement? Thanks in advance.

How do I rename a column in an SQLite database table?

I need to rename table columns in an SQLite database. This similar question doesn't mention SQLite. From the documentation of ALTER TABLE I gather that it's not a single statement.

Hi all,
I have an issue I don't understand: when i save values to a boolean column they seem to be saved as strings (true, false, or in the case of accidental error in inserting some random other strings).

This is on a local d1 database in development.

I was under the impression that values would be converted to 0 or 1 automatically (or error thrown if not truthy or falsy). Is this not correct?

I

Isaac McFadyen•8/16/24, 7:12 PM

So yes,

true

true

and

false

false

will be cooerced into integers, but SQLite (which D1 uses) also has the concept of "flexible datatypes" that other DB engines don't have: https://sqlite.org/datatype3.html

I

Isaac McFadyen•8/16/24, 7:12 PM

It means you can insert a string into an integer column, or an integer into a string column, and the DB engine will just accept it

I

Isaac McFadyen•8/16/24, 7:13 PM

You can use STRICT tables if you want datatypes enforced: https://sqlite.org/stricttables.html

S

Steven•8/16/24, 7:14 PM

mm, okay. Thanks. Good to know.

But I do have 'true' and 'false' values in my boolean column. Those should be converted to 1 & 0 then right? Even without STRICT

I

Isaac McFadyen•8/16/24, 7:15 PM

I'm not sure if it's case-sensitive or not?

S

Steven•8/16/24, 7:18 PM

mm, i'll do a typecheck. maybe it's getting turned into a string somewhere

Heyyyy

I'm getting started with D1 databases for my app.
I have 3 separate databases and want to put it into my local wrangler.toml

I don't know how to input multiple databases into it, the docs only show how to do one database like so:

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

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

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

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

If someone could lead me the right way, you would be madd af ngl

I made a SvelteKit project but what I don't understand is how to work with D1 in development. I would ideally like to start the SvelteKit app normally (

pnpm dev

pnpm dev

) to quickly iterate on the UI, but have D1 accessible like I would by having a development docker image of a remote database. Currently I can only have a functioning version of my app when building the ui and then starting

wrangler pages dev .svelte-kit/cloudflare

wrangler pages dev .svelte-kit/cloudflare

(but since it relies on a build, I would have to re-run the command after every change to have a functioning app in development). What am I missing?

In

src/routes/api/test/+server.ts

I have:

import type { RequestHandler } from '@sveltejs/kit';

  return new Response(JSON.stringify(result));

};

And in my

src/app.d.ts

src/app.d.ts

:

declare global {
  namespace App {
    interface Platform {
      env: {
        db: D1Database;

    }
  }
}

    interface Platform {
      env: {
        db: D1Database;
      };
    }
  }
}

export {};

(where does the

D1Database

D1Database

type come from?)

but when running with

pnpm dev

pnpm dev

and I navigate to

localhost:5173/api/test

localhost:5173/api/test

I get the following in the console:

TypeError: Cannot read properties of undefined (reading 'prepare')

TypeError: Cannot read properties of undefined (reading 'prepare')

. If I build, then run

wrangler pages dev .svelte-kit/cloudflare --d1 db=[uuid-here]

wrangler pages dev .svelte-kit/cloudflare --d1 db=[uuid-here]

the error is just because I haven't made the table, but would otherwise work.

I don't know about the binding it should be generating, because I don't seem to have any(?), but what also strikes me is that i can't just run

wrangler pages dev

wrangler pages dev

, but I have to specify both the folder and the

--d1

Hi, I'm using D1 in SvelteKit.

I want to prerender all of my pages because the content only needs to be updated occasionally (every few weeks), on build I want to fill in the content of my pages with the content in the DB.

I can't seem to get it to work with adapter-static or adapter-cloudflare because the platform.env.DB object isn't bound at build time. This happens both if I try building locally and on Cloudflare Pages.

Any advice?
