Maximum arguments per SQL function    32

Why only 32? Is this limit going to get bigger?

SQLite actually recommends a maximum of 8 for high security deployments (i.e Cloudflare D1) so I expect 32 is the maximum they will go, since that's fairly generous already.

I tried making a request to /query/batch and I get page not found

Up•10/14/23, 3:46 PM

anyone know what I'm doing wrong when trying to dump my DB?

const dump = await c.env.DB.dump();
    return new Response(dump, {
        status: 200,
        headers: {
            'Content-Type': 'application/octet-stream',
            'Content-Disposition': 'attachment; filename="sqlite.db"',
        }
    });

const dump = await c.env.DB.dump();
    return new Response(dump, {
        status: 200,

Matt Silverlock•10/14/23, 8:09 PM

I think you’re mixing up a standalone example with D1’s official API. I strongly recommend slowing down a tad and reading the docs:

SSamantas5855 I tried making a request to /query/batch and I get page not found

Matt Silverlock•10/14/23, 8:09 PM

The example you are referring to has nothing to do with D1’s official REST API.

Matt Silverlock•10/14/23, 8:11 PM

I invite folks to open GitHub issues so we can understand where/why they are running into limits -> allows us to increase them where it makes sense to. It’s not “fixed” at 32, but if you’re generating 1000+ then something is likely wrong with the query. This is why we ask folks to open issues (or use the form linked in the docs)

MMatt Silverlock The example you are referring to has nothing to do with D1’s official REST API.

Samantas5855OP•10/14/23, 10:52 PM

is there any example of performning batch commands with the official d1 rest api?

Samantas5855OP•10/14/23, 10:53 PM

it's the last piece that's missing to complete the implementation

Cyb3r-Jak3•10/14/23, 11:17 PM

You won't get the same transaction benefits as using a worker but something like

INSERT INTO 'tablename' ('column1', 'column2') VALUES
  ('data1', 'data2'),
  ('data3', 'data4'),
  ('data5', 'data6'),
  ('data7', 'data8');`

INSERT INTO 'tablename' ('column1', 'column2') VALUES
  ('data1', 'data2'),
  ('data3', 'data4'),
  ('data5', 'data6'),
  ('data7', 'data8');`

as a statement should work. Do also keep in mind that the API has a rate limit of 1200 requests per 5 minutes which is another reason deploying your own worker as an REST endpoint is recommended

Samantas5855OP•10/15/23, 12:12 AM

this has a limit of 32

Samantas5855OP•10/15/23, 12:12 AM

that's why I want batch

Cyb3r-Jak3•10/15/23, 12:31 AM

Ah gotcha then to batch you’ll need to run the proxy worker

Kaique Nunes•10/15/23, 8:39 AM

can I create trigger functions in D1 ? For example, I need to auto update a counter in table B when there is a new insert in table A

CCyb3r-Jak3 Ah gotcha then to batch you’ll need to run the proxy worker

Samantas5855OP•10/15/23, 9:36 AM

Yeah but that would cost extra

Samantas5855OP•10/15/23, 9:37 AM

It would make sense if the rest api just had an endpoint for it

Hello Cloudflare community

. I need help accessing tables in databases. I have created a database and binded it to my worker through workers.toml file. But when I make a search in a particular table, it gives "no such table" error. Here is an image of tables in my database, "Customers" is just for test purposes.

Yasin•10/15/23, 2:35 PM

app.get('/posts/:lang/:slug/comments', async c => {

    const { results } = await c.env.comDB.prepare(

app.get('/posts/:lang/:slug/comments', async c => {

    const { results } = await c.env.comDB.prepare(

SELECT name, sql FROM sqlite_master

);
        return c.text(results, 200);

}

);
        return c.text(results, 200);

}

Here I am just trying to list all tables

Yasin•10/15/23, 2:36 PM

here is the response, no tables

Wrangler dev uses local mode by default so it doesn’t use the values in the dashboard. You can add values by running the d1 execute command with the

Actually looking at your code you never execute the query. You need to add

.all()

.all()

What does your schema look like? SQLite doesn't have a concept of boolean and uses an integer instead

oh lol, well it is somehow a boolean

how is this possible

Ah instead of using

true

true

use

Might be worth asking in their discord if this is a known thing

riskiidrus•10/16/23, 3:08 AM

Does anyone know why D1 feels slow for simple queries or commands?

I live in Indonesia, I access D1 from there. This is what the query or command looks like:

SELECT * FROM users WHERE id = ? LIMIT 1

.....

UPDATE user SET ..... WHERE id = ?

Even the User Registration Process took a few seconds for me to complete. I thought it was just a problem of my slow internet connection, but when I tried to deploy it on Pages, it made no difference.

Isn't it on the Page "https://pages.cloudflare.com" that Cloudflare claims that they run the Pages Project on the Cloudflare Edge Network which is up to 115% faster than competing platforms?

I'm afraid this will be a Bad End User Experience.
