Hi guys just a quick question. has anyone ever succeeded in running a local instance

wrangler pages dev

wrangler pages dev

bound to a local instance of

D1

D1

started up with something like

pnpx wrangler -c wrangler.toml d1 execute DB --local --file=migrations/001.sql

pnpx wrangler -c wrangler.toml d1 execute DB --local --file=migrations/001.sql

? Just want to make sure this is a supported use case for

D1

D1

in the Beta stage @ the moment. Note: I already have a working

D1

D1

setup with pages on Cloudflare. I'm interesting in running locally. So my question essentially is just if whether this is already supported or not.

i have no problems running D1 locally? just have to remember as you are trying that its a seperate db from remote so you need to migrate/seed the local also.

Varna•10/12/23, 9:22 AM

I dumped a 300mb dump.sql file and fed it to

pnpx wrangler d1 execute db_name --local --file=./src/dump/dump.sql

pnpx wrangler d1 execute db_name --local --file=./src/dump/dump.sql

but it stayed the same for past 1h:

Hi @forslunds , were you able to connect your local cloudflare pages dev instance to your local D1? I'm having issues with binding since my Env.DB is null after migrations. D1 stand-alone is working well in my case.

itsmatteomanf•10/12/23, 10:06 AM

That tells me you have very long single queries... which are probably gonna fail.

itsmatteomanf•10/12/23, 10:07 AM

Can you try and reduce the size of each query or do it in parts?

Varna•10/12/23, 10:24 AM

not sure. I'm trying to figure out if it is possible to migrate MySQL -> D1. I could import only schema, and then setup a background Worker to populate the data during night or smth. But I couldn't manage to run a Worker that could connect to a MySQL db, so I would probably need to put the dump.sql on a R2 first.

Varna•10/12/23, 10:29 AM

well, people will need a way to migrate into D1 after release anyways, so I guess this is the chance to find or make an example for such case

itsmatteomanf•10/12/23, 10:29 AM

You can just reduce the size of the .sql dump file by itself...
Just do one with the one schema, one with the data (or multiples depending on the size of the file itself).

itsmatteomanf•10/12/23, 10:31 AM

Just note that each statement can't be more than 100kB, but you can have as many statements as you want (there is a size limit to the total D1 Query the API accepts, I've hit it, but I haven't found it explicitly listed so can't say exactly)... cc @rozenmd @Matt

you can debug that your tokens are right via

MMax (@rozenmd)i dont understand the question tbh

itsmatteomanf•10/12/23, 11:19 AM

Like, I had a ~50MB .sql file, which I executed and failed. If the limit is 100MB on the gateway (assuming it as the one used by other endpoints, like KV…) it assumes there is a ton of overhead on the actually query, which seems strange

Max (@rozenmd)•10/12/23, 11:28 AM

like if you have a 49mb file, does it work?

Max (@rozenmd)•10/12/23, 11:30 AM

i'm just saying i doubt we changed the default api gateway limits for d1 since the alpha would crash if you looked at it wrong

that'll be it then -

CLOUDFLARE_ACCOUNT_ID=1234 CLOUDFLARE_API_TOKEN=4321 wrangler d1 execute test-database --command="SELECT * FROM Customers"

Max (@rozenmd)•10/12/23, 12:06 PM

otherwise you need to add

and

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

Samantas5855•10/12/23, 8:38 PM

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 INSERTINSERT.
