The only case when Sqlite is not suitable for your project, is when more than one server/instance of your app needs to access the database.

Your app is probably not in this category.

Bbun does worker use TCP for D1 or HTTP? like does it count as an outgoing request?

Hello, I’m Allie!•2/20/24, 10:21 AM

It uses something internally, which afaik isn't quite TCP or HTTP

bun•2/20/24, 10:25 AM

so queries dont count as outgoign requests?

Hello, I’m Allie!•2/20/24, 10:25 AM

Not quite, since the D1 Layer that is on top of SQLite handles simultaneous connections. It can't actually process multiple requests simultaneously, but it can store requests in a queue. I would note too that while you can use D1 outside of Cloudflare, it isn't meant to be used that way, and thus it is a bit unergonomic

Bbun so queries dont count as outgoign requests?

Hello, I’m Allie!•2/20/24, 10:26 AM

They do. No matter the underlying protocol, an outgoing I/O op is counted as a "request"(though opening a TCP socket is a single connection, even if you do multiple things with it)

Hello, I’m Allie!•2/20/24, 10:26 AM

Hello, I’m Allie!•2/20/24, 10:32 AM

Not necessarily. While some of the limits are applied by Cloudflare directly, others are in place because the database may not be stable above those limits. You might be able to push it farther, but CF can't guarantee that it will function correctly, so you can't raise the limit that far

Oh yeah, if you do a batch with reused statements especially, it’s in the 100s of thousands of inserts per call in a lot cases. Performance wise is really good.

itsmatteomanf•2/20/24, 1:08 PM

There are a couple of issues with reliability (but they are very rare now and they are being fixed), but for the most part it’s really good.

Original message was deleted

itsmatteomanf•2/20/24, 1:10 PM

That even seems slow, but it depends on what you use (Worker or HTTP API?) and the amount of data per row + number of indexes on top

my rows are smaller!

Yes, but they have to be created when the script receives its first event. You can't create them before the event arrives

Tony Leung•2/21/24, 4:59 AM

Hi guys, I'm querying data with the query above, but it seems like scanning too much data. I've set index for

p.posted

p.posted

and

p.retry

p.retry

but it's still scanning the whole table

. Is there anyway to reduce scanned rows of the query above? I'm running this query every minutes so everyday I'm wasting 10-20k scanned row. This table is going to grow much larger so the waste will be more significant

Hi everyone.. How to create REST API for CRUD operations in D1

stefanoros•2/21/24, 10:45 AM

Hello everyone, i'm trying to set up a simple many-to-many join

SELECT *
    FROM categories
    JOIN images_categories ON categories.id = images_categories.category_id

SELECT *
    FROM categories
    JOIN images_categories ON categories.id = images_categories.category_id

can you post the exact code, including JS/TS that you're using?

stefanoros•2/21/24, 10:57 AM

sure

    let result = await platform!.env.DB.prepare(
        `SELECT *
    FROM categories
    JOIN images_categories ON categories.id = images_categories.category_id
    JOIN images ON images_categories.image_id = images.id;
    `
    ).all();

    FROM categories
    JOIN images_categories ON categories.id = images_categories.category_id
    JOIN images ON images_categories.image_id = images.id;
    `
    ).all();

if I remove one join statement it works

that's weird - i've only seen that error with the parser failing to understand comments

Max (@rozenmd)•2/21/24, 11:00 AM

does it work if you combine the SQL onto a single line? like

`SELECT * FROM categories JOIN images_categories ON categories.id = images_categories.category_id JOIN images ON images_categories.image_id = images.id;`

`SELECT * FROM categories JOIN images_categories ON categories.id = images_categories.category_id JOIN images ON images_categories.image_id = images.id;`

, or two individual indexes?

Tony Leung•2/21/24, 11:50 AM

yes, I'm having a composite index like this:

CREATE INDEX post_posted_retry_idx ON post (posted, retry);

CREATE INDEX post_posted_retry_idx ON post (posted, retry);

Tony Leung•2/21/24, 11:51 AM

it should cover both

posted

and

retry

retry

if I place the condition in the correct order right?

Tony Leung•2/21/24, 11:54 AM

base on this document: "https://www.sqlite.org/optoverview.html", both

Hi guys! Good day to you all. Does D1 really consider 0 as NULL?

I have a NOT NULL constraint on my table.. when saving 0, it returns a

Error: D1_ERROR: FOREIGN KEY constraint failed
      at D1Database._sendOrThrow (cloudflare-internal:d1-api:66:19)

Error: D1_ERROR: FOREIGN KEY constraint failed
      at D1Database._sendOrThrow (cloudflare-internal:d1-api:66:19)

I have already logged the input, and confirmed, it is indeed 0 and typeof number.. and is absolutely NOT null... but it still results to an error..

If ever, what would be the workaround for this? I definitely would wanna save 0 but do not want a null

sten•2/21/24, 12:14 PM

SQLite supports a limited subset of ALTER TABLE. The ALTER TABLE command in SQLite allows these alterations of an existing table: it can be renamed; a column can be renamed; a column can be added to it; or a column can be dropped from it.

So if I want to alter the datatype of a column, I would first need to drop that column and then add it again with a new datatype?

Max (@rozenmd)•2/21/24, 12:41 PM

Original message was deleted

sten•2/21/24, 12:41 PM

There's gotta be a good way to do this though?
I guess best way is to

Rename original table with different name.
Create new table with same name as previous table have with desired column type.
Copy all previous data from old table (renamed table) to newly created table.
Drop renamed table.
