Just a curios question.
Will D1 make out of workers environment and become like a standalone DB as a service?

Is it possible to perform many insertions without repeating the query on the https api? Something similar to this syntax:

kian•10/13/23, 1:03 AM

There's nothing special about how D1 handles it, so you can do whatever SQLite supports. For example, you can repeat the values to insert several rows.

INSERT INTO test (id) VALUES (1), (2), (3), (4), (5)

INSERT INTO test (id) VALUES (1), (2), (3), (4), (5)

kian•10/13/23, 1:05 AM

If you wanted to use parameters, then you'd do this.

{
  "params": [
    1,
    2,
    3,
    4,
    5
  ],
  "sql": "INSERT INTO test (id) VALUES (?), (?), (?), (?), (?)"
}

{
  "params": [
    1,
    2,
    3,
    4,
    5
  ],
  "sql": "INSERT INTO test (id) VALUES (?), (?), (?), (?), (?)"
}

kian•10/13/23, 1:05 AM

You can take a look at https://www.sqlite.org/lang_insert.html for the syntax of

INSERT

kian•10/13/23, 12:43 PM

Just send more than one query then? 100 in one query seems more than acceptable.

SQLite’s recommended high security value is 10, so D1 is already 10x’d that.

GuillaumeLakano•10/13/23, 12:48 PM

Thank you for your feedback, few weeks ago I could create one in local, I don't remember how, may be with the --local ( or without the --remote flag, this is not really clear when we need one or not )

Currently, if I don't uses the --local flag, it's create the DB in remote ( and without any --remote flag )

Elliot Hesp•10/13/23, 2:14 PM

I've got a wranger.toml file like so

[env.production]
name = "krypton"
logpush = true
workers_dev = true
d1_databases = [
  { binding = "DB", database_name = "krypton", database_id = "<123>" },
]

name = "krypton"
logpush = true
workers_dev = true
d1_databases = [
  { binding = "DB", database_name = "krypton", database_id = "<123>" },
]

When I deploy, it deploys with the D1 database as expected bound. However when I run:

wrangler d1 migrations apply krypton

wrangler d1 migrations apply krypton

I get the error,

Talaat•10/13/23, 2:45 PM

Hello
Can anyone guide me on how to connect workers with Cloudflare d1 and different environments
The connection is fine if i go with the default wrangler.toml configuration but the moment i go with this approach (Check code below) the db connection never happens at all

Approach i am trying to use

This is a staging environment

[env.staging]
d1_databases = [
{ binding = "DB", database_name = "<DATABASE_NAME_1>", database_id = "<UUID1>" },
]

This is a production environment

[env.production]
d1_databases = [
{ binding = "DB", database_name = "<DATABASE_NAME_2>", database_id = "<UUID2>" },
]

MY BINDING

export type Bindings = {
    DB: D1Database;
    ACCESS_TOKEN_SECRET: string;
};

export type Bindings = {
    DB: D1Database;
    ACCESS_TOKEN_SECRET: string;
};

my endpoint (Using hono js)

app.get('/', async (c) => {
    const res1 = await c.env.DB.prepare('SELECT * from testTable;').all();
    return c.json({ status: 'success', message: res1 });
});

app.get('/', async (c) => {
    const res1 = await c.env.DB.prepare('SELECT * from testTable;').all();
    return c.json({ status: 'success', message: res1 });
});

Talaat•10/13/23, 2:45 PM

i then get the following error

Does

work?

Talaat•10/13/23, 3:07 PM

unfortunately no

however if I change
[env.dev.vars]
to
[env.dev]
it does work but it only picks up the db connection and ignore other variables like the access token

Cyb3r-Jak3•10/13/23, 3:12 PM

Talaat•10/13/23, 3:27 PM

Ok this is crazy but i found the issue and it would be reall super nice if we could get a better solution to this
for D1 connection you need to use
[env.dev]

and for actual environment variables you need to use
[env.dev.vars]

Yes many would say that its on the documentation (both in workers and D1 docs) but its super difficult to ge this correct from the first time
i spent an entire day on this

AND PLZ dont get me wrong, cloudflare solutions are super amazing but if we could get a better way of doing this environment thing

Lane C•10/13/23, 11:06 PM

I did have one index to fix and that has increased performance a lot.My db was also the alpha version, so I recreated with beta, I have no idea how that happened. Its still about 1.2 seconds to load 10 records on a query with 4 joins and a base table of 10k rows. FWIW here is a front end demo. if you page thru enough times, you'll hit a page that hasn't been cached and can see the latency. https://client-demo.sonicjs.com/
