It should auto skip that prompt if detcted as CI or non-interactive. Are you seeing the prompt appear and thus CI fails or that when it applies migration there are no changes?

It’s an example: in practice, those values will be user provided and so you always want to use a parameterized query for security.

What are you trying to do? Most SQL functions accept UTF-8 encoding.

kojo•10/9/23, 10:17 PM

heya, good folks of d1!

I'm currently building a project on cloudflare workers+pages+d1 that I'd like to be forkable. So the ideal workflow for the users is:

fork the repo of my deployed solution
set things up
run GitHub Action and get a URL

Now, for project without D1 I can at least theoretically imagine how the step 2 would look like. I. e. "create a cloudflare account, get token, paste token to GitHub Action Secrets". But with D1 I'm a bit stuck.

The reason I'm stuck is that the unique id of the database is in wrangler.toml and that the d1 is not even creatable in the dashboard until the first worker is deployed. So the user flow for setup becomes something like:
a. run deployment action with database turned off. It will deploy the worker that can't work because there's no database
b. go create a database in the dashboard
c. copy-paste the details of the database from dashboard to repo
d. deploy the solution again - this time with database enabled

Is there a better way? Am I missing something?

kian•10/9/23, 10:31 PM

It's not specific to D1, it's just your usual SQLite prepared statements. Executing a SQL statement requires compilation, so it's compiled and then held in memory for later re-use (all you have to do is bind new parameters rather than re-evaluate the entire query).

kian•10/9/23, 10:32 PM

The execution context in this case is the Durable Object that's backing your D1 database, so it'll hang around after inactivity before it's eventually evicted (assuming no more requests).

kian•10/9/23, 10:33 PM

If you had a generic query, like

SELECT email FROM users WHERE name = ?1

SELECT email FROM users WHERE name = ?1

, then SQLite doesn't need to re-compile

SELECT email FROM users WHERE name =

SELECT email FROM users WHERE name =

it can just take that statement from last time, bind a new
```
?1
```
```
?1
```
and execute it.

Kkian The execution context in this case is the Durable Object that's backing your D1 ...

Michał•10/9/23, 10:40 PM

So, in layman terms, this should improve performance across multiple worker executions, not just within one worker run?

Michał•10/9/23, 10:40 PM

Lovely

kian•10/9/23, 10:47 PM

https://x.com/KentonVarda/status/1659551757796515846?s=20 is a good thread by Kenton (the Tech Lead of Workers) on the implementation of the new storage subsystem (still Durable Objects, but SQLite in the runtime).

Kenton Varda (@KentonVarda)

So I've spent the last ~three months writing a new distributed storage engine based on SQLite and it has been FUN!

The alpha backend was WebAssembly in DOs, likely similar to https://github.com/rkusa/wasm-sqlite, which ran into the issues that Kenton talks about.

kojo•10/9/23, 10:59 PM

"d1_databases[0]" bindings must have a "database_id" field

why? why can't I identify the database by name only, it would've been so much easier

kian•10/9/23, 11:01 PM

There's a TODO to allow that

I created a database with wrangler, added some tables also with wrangler using SQL commands and the database shows up in the dashboards, but not the tables. Yet the number of queries climbs (with delay wrt the actual wrangler-submitted questions).
Is that expected?

I would really appreciate a way to backup d1 database locally. I pitched D1 storage but as a fail safe, the client didnt trust enough on time travel and wanted a way to take backup locally on disk.

what you're seeing is the difference between how long d1 took to execute your query, and how long it took to go from request -> query -> response

we return just the query response time, since that's controllable by the user (request less data/index your tables etc)

nothing measurable, so at most a couple ms - and the queries drizzle generates are now pretty efficient too, so in some cases it might be better on the DB site if we don't hand-write everythign

Hi!
An assigned UUID to a D1 database will stay the same forever, even if we move from Beta to GA, or if we need to uses Time Travel ?
To give some context, I'm asking because as the concept of database-per-user use-cases will be soon possible (only manual bindings in wrangler.toml for now and limited to ~5K), I suppose the future dynamic binding will uses the UUID assigned to the D1 database. Then, we want to save this UUID in other databases, and want to be sure this UUID will never change later, we could even consider it as a replacement of a classic id_customer field.

Isaac McFadyen•10/10/23, 3:21 PM

Time travel = yes, stable UUID
Alpha -> Beta, not stable, because you need to recreate the database
Beta -> GA, probably stable, an employee has said here before that there shouldn't need to be any migrations involving recreating of databases. Ref: https://canary.discord.com/channels/595317990191398933/992060581832032316/1153997053861576744

Isaac McFadyen•10/10/23, 3:21 PM

But D1 is in beta and no guarantees are made. If something goes wrong or DBs need to be migrated the UUID may change.
