literally just says have your wrangler.toml which i already know is right

H

Hearse•11/23/23, 12:15 PM

and then run the command.

H

Hearse•11/23/23, 12:16 PM

ill do that though

actually wait

it seems like their docs are written for you to clone their example project

because the file is here: https://github.com/drizzle-team/drizzle-orm/blob/main/examples/cloudflare-d1/drizzle/0000_short_lockheed.sql

wtf

oh okay, i got it, you have to generate the sql file with ur schema and then use the generated file name

forslunds•11/23/23, 12:59 PM

Yes, generate migrations/schema with drizzle and upload with wrangler/d1

Hey

If I have two simultaneous write operations that increment the same cell in D1 using one-shot sql query. Will it work right out of the box or will I need to implement something special for this?

R

Rob M.•11/24/23, 11:01 AM

SQL Example:

UPDATE table_name 
SET column_name = column_name + 1
WHERE condition;

UPDATE table_name 
SET column_name = column_name + 1
WHERE condition;

UPDATE table_name 
SET column_name = column_name + 1
WHERE condition;

UPDATE table_name 
SET column_name = column_name + 1
WHERE condition;

it'll work, D1 uses a single writer

if you get a syntax error in the console, you'll get a syntax error in the worker too, it's the same engine

Did you managed to alter and add foreign key, asking because if that works might be something wrong with my column definitions

Max (@rozenmd)OP•11/24/23, 2:20 PM

I did, here's an example:

CREATE TABLE sensors (
    id INTEGER PRIMARY KEY,
    name TEXT NOT NULL
);

INSERT INTO sensors (name) VALUES ('sensor1');
INSERT INTO sensors (name) VALUES ('sensor2');

CREATE TABLE sensor_data (
    id INTEGER PRIMARY KEY,
    value REAL NOT NULL,
    timestamp INTEGER NOT NULL
);

INSERT INTO sensor_data (value, timestamp) VALUES (1.0, 1234);
INSERT INTO sensor_data (value, timestamp) VALUES (2.0, 1235);

ALTER TABLE sensor_data ADD COLUMN sensor_id INTEGER REFERENCES sensors(id);

CREATE TABLE sensors (
    id INTEGER PRIMARY KEY,
    name TEXT NOT NULL
);

INSERT INTO sensors (name) VALUES ('sensor1');
INSERT INTO sensors (name) VALUES ('sensor2');

CREATE TABLE sensor_data (
    id INTEGER PRIMARY KEY,
    value REAL NOT NULL,
    timestamp INTEGER NOT NULL
);

INSERT INTO sensor_data (value, timestamp) VALUES (1.0, 1234);
INSERT INTO sensor_data (value, timestamp) VALUES (2.0, 1235);

ALTER TABLE sensor_data ADD COLUMN sensor_id INTEGER REFERENCES sensors(id);

CREATE TABLE sensors (
    id INTEGER PRIMARY KEY,
    name TEXT NOT NULL
);

INSERT INTO sensors (name) VALUES ('sensor1');
INSERT INTO sensors (name) VALUES ('sensor2');

CREATE TABLE sensor_data (
    id INTEGER PRIMARY KEY,
    value REAL NOT NULL,
    timestamp INTEGER NOT NULL
);

INSERT INTO sensor_data (value, timestamp) VALUES (1.0, 1234);
INSERT INTO sensor_data (value, timestamp) VALUES (2.0, 1235);

ALTER TABLE sensor_data ADD COLUMN sensor_id INTEGER REFERENCES sensors(id);

CREATE TABLE sensors (
    id INTEGER PRIMARY KEY,
    name TEXT NOT NULL
);

INSERT INTO sensors (name) VALUES ('sensor1');
INSERT INTO sensors (name) VALUES ('sensor2');

CREATE TABLE sensor_data (
    id INTEGER PRIMARY KEY,
    value REAL NOT NULL,
    timestamp INTEGER NOT NULL
);

INSERT INTO sensor_data (value, timestamp) VALUES (1.0, 1234);
INSERT INTO sensor_data (value, timestamp) VALUES (2.0, 1235);

ALTER TABLE sensor_data ADD COLUMN sensor_id INTEGER REFERENCES sensors(id);

IvanN•11/24/23, 2:23 PM

But you created new column and add key, i want to alter existing column

I

IvanN•11/24/23, 2:24 PM

However if that works i can add new column add key and run sql to populate the column

I

IvanN•11/24/23, 2:24 PM

That will save me a lot of time

I

IvanN•11/24/23, 2:25 PM

Thanks

Max (@rozenmd)OP•11/24/23, 2:25 PM

sqlite is a bit funky with alter table, only a subset of the sql spec is implemented: https://www.sqlite.org/lang_altertable.html

Ccras6 @Ivan Najdovski i have the same question actually

I

IvanN•11/24/23, 5:56 PM

hey @cras6 so this solution works for me,

Create new column "temp_column"
Update temp_column with value from column that you want to have the FOREIGN KEY

UPDATE your_table
SET temp_column = column_foreign_key_but_not_set;

Drop the column_foreign_key_but_not_set that you want to have the FOREIGN KEY
Create the same column with FOREIGN KEY column_foreign_key
solution by @rozenmd thanks btw.
ALTER TABLE your_table ADD COLUMN column_foreign_key INTEGER REFERENCES ref_table(ref_column);
Copy content from temp_column to the one you created in step 4 column_foreign_key
Drop the temp_column

A bit of steps but works

Hi, I have a question around generated columns in D1.

I've read through this page and I think it does what I want, but I'm a bit unsure how to apply it.

Essentially, I have columns A and B, I want to create column C which is a hashed value of A and B.
I could do this through code in my worker, but ideally I want it done at DB level (seems safer and it would pollute my worker code).

I see that SQLite has no hashing functions built in though, so is this even possible?

Thanks!

Are you getting “no such table: users” (as per your comment) or “no such table: customers” as per the error text you posted? Did you create the table first?

liorgr•11/24/23, 9:29 PM

Am I the only one experiencing issues with D1?
Dashboard doesn’t load & API calls are failing

C

Constantin•11/24/23, 9:29 PM

sorry i was testing with both users and Consumers. yes the consumers table is created and i can query it.

C

Constantin•11/24/23, 9:30 PM

from wrangler it works, but from the code Astro it does not

Constantin•11/24/23, 9:30 PM

the KV however works ..

liorgr•11/24/23, 9:36 PM

D1 dashboard is stuck, is it only for me?

liorgr•11/24/23, 9:37 PM

And an API token that worked up until 2 hours ago is not working, even though it says it’s active and no changes were made

L

liorgr•11/24/23, 9:48 PM

@Alexander.Xtreme I get the same

L

liorgr•11/24/23, 9:48 PM

Also if you check the network request for the dashboard, it gets similar error

I think you need to run `npm run generate` for drizzle to create the SQL
