as in, are you using D1 as a single database for an API that your frontend talks to? how many requests per second?

it throws "Error: must provide --command or --file" if there's an empty string too

I think you need to run

npm run generate

npm run generate for drizzle to create the SQL

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;

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)•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

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