Can you run just a very basic query - start from scratch. Just

await db.exec("PRAGMA table_list")

await db.exec("PRAGMA table_list")

- and nothing else? Your binding appears fine. You aren't returning any results (because it's an INSERT without any RETURNING) - what do you expect to happen? It should just insert without an error.

Unsmart•9/25/23, 5:01 PM

Defining you d1_databases array under a

[vars]

[vars]

table will make it where your D1 bindings are not defined unless you changed your format to use a table for

d1_databases

d1_databases

also which is why you started to get an error when you moved it.

These 2 toml files are not equal:

d1_databases = [
  { binding = "name", ... }
]

[vars]
hello = "world"

d1_databases = [
  { binding = "name", ... }
]

[vars]
hello = "world"

[vars]
hello = "world"

d1_databases = [
  { binding = "name", ... }
]

[vars]
hello = "world"

d1_databases = [
  { binding = "name", ... }
]

i'm running:

var coolio200 = await env.MYDATABASE_DB.exec("PRAGMA table_list")
console.log("here is coolio100")
console.log("here is coolio200: " + JSON.stringify(coolio200))

console.log("here is coolio100")
console.log("here is coolio200: " + JSON.stringify(coolio200))

and it doesn't print out the console log, it just stops

question regarding setting up a database which creates the best space savings for a field when nothing is set:
a. email TEXT
b. email TEXT DEFAULT ''

captain•9/26/23, 4:17 PM

so if nothing is set in the email in part a, the field would be filled with "NULL" just wondering if behind the scenes that takes up more space than choice b

digeratidave•9/26/23, 4:19 PM

what is the best practice for adding a column to an existing D1? Is the Alter command from wrangler the only method currently supported or are there any other methods such a Console from the Dashboard?

captain•9/26/23, 4:45 PM

@Matt just wondering if you had any incite on the "under the hood" storage of how D1 saves things, is there more saving a field as "null" or 0 character string?

Unsmart•9/26/23, 4:49 PM

captain•9/26/23, 5:45 PM

Another question regarding fields, i have a field set to:

time_stamp_updated INTEGER DEFAULT CURRENT_TIMESTAMP,

If I make an entry and don't set this field, it sets it to:

2023-09-26 17:40:44

I was thinking it would set it to to the epoch time similar to Date.now() which would be an integer like: 1695750044698

When going to dashboard and then attempting to update, an update can't occur because the dashboard flags the entry at that time_stamp_updated area.

That said, it still saved "2023-09-26 17:40:44" which is not an integer...how did it do that?

captain•9/26/23, 5:53 PM

Also noticing workers sets Date.now() to something like 1695750600382 while D1 sets unixepoch('now') to 1695750600

Isaac McFadyen•9/26/23, 5:53 PM

It might, but that would deviate from SQLite behavior, which I doubt they'd want to do.

Isaac McFadyen•9/26/23, 5:54 PM

It would mean every time someone imported a SQLite database the user would need to know to convert manually.

captain•9/26/23, 5:54 PM

true

captain•9/26/23, 5:54 PM

perhaps the D1 wizzards could deviate slightly and created a new unixepoch function ie, unixepochD1

that would use ms, given the environment its used in

MMatt Silverlock `timestamp_updated_ms` - give your names units 🙂

captain•9/26/23, 6:37 PM

how would one define that...? I tried time_stamp_updated INTEGER DEFAULT (timestamp_updated_ms('now')) AND time_stamp_updated INTEGER DEFAULT timestamp_updated_ms

captain•9/26/23, 6:38 PM

but no success

captain•9/26/23, 6:43 PM

or are you just saying label it with the expected units?

Can you run just a very basic query - start from scratch. Just `await db.exec("PRAGMA table_list")`
