D1 is strongly consistent so yes, it will work.

I

Isaac McFadyen•12/29/23, 3:46 PM

Just make sure to increment in the same SQL query as the fetch (like

UPDATE foo SET counter = counter + 1

UPDATE foo SET counter = counter + 1

UPDATE foo SET counter = counter + 1

UPDATE foo SET counter = counter + 1) rather than fetching and then adding 1 in your code.

In the future there will be read replica support, but it should still theoretically work since all writes will be propagated back to the master which has the latest writes.

PPepper I was just using javascript and the api to test it out. This isn't the actual ta...

Definitely use bindings as suggested. Manually inserting values like this can lead to SQL Injection Attacks.

Unfortunately not unless they specifically say they support D1 which it doesn't look like they do.

I

Isaac McFadyen•12/29/23, 6:17 PM

D1 has it's own API because SQLite doesn't have a standardized version, so they'd need to explicitely support D1.

Can you only drop one table at a time against D1?

npx wrangler --env dev d1 execute workers-db --command="DROP TABLE account"

npx wrangler --env dev d1 execute workers-db --command="DROP TABLE account"

npx wrangler --env dev d1 execute workers-db --command="DROP TABLE account"

npx wrangler --env dev d1 execute workers-db --command="DROP TABLE account"
I have tried chaining like

account, user, comment

account, user, comment

account, user, comment

account, user, comment but it responds with

near "comment": syntax error at offset 19 [code: 7500]

near "comment": syntax error at offset 19 [code: 7500]

For D1 with pages, you can do pretty much all the same dev locally as workers but use remote dev because pages doesn't support that. I use the standard wrangler file in my pages project for interacting with bindings. Just have to remember to use the dashboard to apply bindings

Yes. There is the REST API but it is rate limited so better making your own with the worker

Does anyone know of any project that is attempting local SQLite replication that would work with D1? For instance, https://github.com/vlcn-io/cr-sqlite and https://electric-sql.com/ are both really cool but not inherently compatible with D1

I'm a little curious why D1 doesn't have a

.get()

.get()

.get()

.get() method to retrieve a single row in the db. Not that it's the end of the world that I have to do .all()[0] but it seems... weird, that I can't just do

db.prepare(blah).bind(somevar).get()

db.prepare(blah).bind(somevar).get()

db.prepare(blah).bind(somevar).get()

db.prepare(blah).bind(somevar).get() ?

<

<Alterion.Dev>•1/1/24, 4:52 PM

like,

const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).get();

// vs
const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).all()[0];

const table = this.#db
