JJonathan Is this normal to nest D1 under the env? I didn't see this in other projects

I

That's because nesting it under env allows configuring different D1 databases per environment (where an environment is actually a separate worker suffixed with the environment name)

It should skip user input if wrangle detects it’s a non-interactive environment or a CI environment. Try setting an environment variable of

anyone understand this error?

"message": [

          "cause": "Type 'undefined' not supported for value 'undefined'"

        }
      ],

This is on an update - on logging the values being batched into the row, I dont see any values that are undefined.

The area where I am not sure is a field type of Blob, and I am trying to update it with an empty array - i.e.:

\"projectRef\":[],

\"projectRef\":[],

\"projectRef\":[],

\"projectRef\":[],

Does the blob type need to be a string or does it accept a pure array?

Hey, quick question. When I do a simple select in a table with 100 rows using some constraints (let's say some column is > than a number) which satisfy only 5 rows, why does it say

rows_read: 100

rows_read: 100

rows_read: 100

rows_read: 100 (aka I get 100 billed rows)? Is it intended or is it a bug? Thanks

Your query has to read the whole table to find those rows.

See https://developers.cloudflare.com/d1/learning/using-indexes/ for how you can optimize.

Use indexes · Cloudflare D1 docs

Indexes enable D1 to improve query performance over the indexed columns for common (popular) queries by reducing the amount of data (number of rows) …

Matt Silverlock•10/23/23, 12:10 PM

(Noting that at 25 billion rows read per month included, you can make that query 250 million times. Don’t worry about optimizing small queries too quickly)

Note that this is the same for any row-based relational database: you have to scan the table to find the rows that match the condition.

You can add indices to reduce the number of sequential scans

No, it's just that

auto_increment

auto_increment

auto_increment is the wrong spelling. It should be

AUTOINCREMENT

AUTOINCREMENT

AUTOINCREMENT

AUTOINCREMENT, and is only valid on a

INTEGER PRIMARY KEY

INTEGER PRIMARY KEY column.

Since

INTEGER PRIMARY KEY

INTEGER PRIMARY KEY

INTEGER PRIMARY KEY will become an alias for the

D1 uses SQLite under the hood, so there will be syntax/grammar differences here and there. Different database engines typically have different extensions to the SQL standard, so what works in one place might not work somewhere else.

joeljuca•10/23/23, 9:15 PM

The TLDR for FKs and/or table constraints in general in SQLite is: they are pretty much set on table creation. IIUC, if you need to seriously change your table constraints, you'll probably need to recreate the table (eg:

CREATE TABLE my_table2

CREATE TABLE my_table2

CREATE TABLE my_table2

CREATE TABLE my_table2, copy all

my_table

my_table

my_table

my_table. data to

my_table2

my_table2

my_table2

my_table2, and then renaming it to

my_table

my_table

my_table

my_table)

You can use the REST API to query your database.

i think its that way in the docs because the --d1 param was added after the toml method so they used that as an example

since d1 was in alpha
