an index is only useful if you're looking for a specific record/types of records.

a good rule of thumb is, if you're using a WHERE clause on anything other than the PRIMARY KEY on a query that runs often, it might be worth indexing it

if you had a column like

user_id

user_id

on

ProductData

ProductData

, you could add an index for that column, and reduce your rows read when querying

ProductData

ProductData

via

SELECT * FROM ProductData WHERE user_id = ?

SELECT * FROM ProductData WHERE user_id = ?

say I have 100s or 1000s of rows I'd like to be able to insert during a query, but those rows are based on user input in such a way where I'd like to prevent sql injection, what's the proper way to handle this scenario?

should I just create a separate d1 statement for each row and bind them individually and then batch that all, is there a clever way to make this into one statement?

I want to create something equivalent to:

INSERT OR IGNORE INTO your_table_name (column1, column2, unique_column)
VALUES 
    (value1_1, value1_2, unique_value1),
    (value2_1, value2_2, unique_value2),
    (value3_1, value3_2, unique_value3),
    ...
    (valueN_1, valueN_2, unique_valueN);

INSERT OR IGNORE INTO your_table_name (column1, column2, unique_column)
VALUES 
    (value1_1, value1_2, unique_value1),
    (value2_1, value2_2, unique_value2),
    (value3_1, value3_2, unique_value3),
    ...
    (valueN_1, valueN_2, unique_valueN);

INSERT OR IGNORE INTO your_table_name (column1, column2, unique_column)
VALUES 
    (value1_1, value1_2, unique_value1),
    (value2_1, value2_2, unique_value2),
    (value3_1, value3_2, unique_value3),
    ...
    (valueN_1, valueN_2, unique_valueN);

INSERT OR IGNORE INTO your_table_name (column1, column2, unique_column)
VALUES 
    (value1_1, value1_2, unique_value1),

Hi,

Recently I started experimenting with Cloudflare to host a website (static) and a dynamic REST API via workers.
Behind the REST API there is a database with approx. 200K rows which I need to periodically import into D1

So last week I did the initial import using Wrangler and it went really smoothly

A few minutes ago I tried to re-import and it failed with:

✘ [ERROR] Received a malformed response from the API

  <!DOCTYPE html>
  <!--[if lt IE 7]> <html class="no-js ie6 oldie" lang="en-US"> <![endif]-->

My import script first executes some

DROP TABLE IF EXISTS ..

DROP TABLE IF EXISTS ..

statements, then creates the tables, and executes the inserts.
Although it failed, all tables were deleted, created and also some data was inserted.

It seems to have failed after approx. 25K rows out of 175K.

Are there any log files or something else I can check to see what happened?

Note I can import this file without any problem in a local sqlite database.

M

Marcel Overdijk•3/22/24, 6:45 PM

Another thing I now noticed is this in my D1 account page:

Rows read
1.25M

Rows written
375.35k

Rows read
1.25M

Rows written
375.35k

Before starting the import it said

and

.
So I can not really explain these numbers as now only ~25K rows were inserted...

yes, although they're working on bringing it up to 10 GB d1-database

Chaika•3/22/24, 7:09 PM

D1, as of right now, wants you to split your data among many databases rather then have one big one, thus the reasons of the limits being like that

But seems like the Latency is high eg: 1,500ms ~ 2,000ms

Yes, that works with remix+vite. I found that it’s not necessary to specify the bindings in the command line when running locally. Just let ‘remix vite:dev’ pick them up from wrangler.toml and include the local bindings in the wrangler.toml.
