what is the best practice for adding a column to an existing D1? Is the Alter command from wrangler

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?

@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

I dont think you should be that worried about saving a few bytes an item like that tbh just do whatever you think best for your application that makes it easy for you to manage

are you sure the way Standard SQL lite does thing behind the scenes i the same as how D1 does it? I don't think its always a 1 to 1 situation...only the cloudflare wizards would know what lies beyond the veil

it's just sqlite https://github.com/cloudflare/workerd/pull/302/files#diff-3009a3da17d76a94673aa828ce6c364fc24e34d889b4995adfc249a0e2a3c754R66-R69

captain•9/26/23, 5:02 PM

so that means...its basically the same size?

https://www.sqlite.org/fileformat2.html#record_format or i mean a someting wit a content length of 0 is Null?

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

Date.now() is in ms, SQLite is in secs.

captain•9/26/23, 5:53 PM

wondering if that would make sense if they were more aligned to both either be in ms or secs?

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

captain•9/26/23, 5:55 PM

that would use ms, given the environment its used in

captain•9/26/23, 6:00 PM

idk maybe its a silly idea

captain•9/26/23, 6:00 PM

i am going to set time_stamp_updated INTEGER DEFAULT (unixepoch('now') * 1000) to aleviate confusion

give your names units

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?

Matt Silverlock•9/26/23, 6:43 PM

^ that. Give your column the name of the units it contains. Not a requirement - just a tip

captain•9/26/23, 6:44 PM

got it! I just set it via: time_stamp_updated INTEGER DEFAULT (unixepoch('now') * 1000)

captain•9/26/23, 6:45 PM

but that said, if setting time_stamp_updated INTEGER DEFAULT CURRENT_TIMESTAMP, i think wrangle should flag that as an error

captain•9/26/23, 6:45 PM

with type mismatch of some sort given CURRENT_TIMESTAMP will save a non integer result
wrangler could check for that when the following line is executed:
wrangler d1 execute <DB_NAME> --file=dbtablecreate.sql

Have you actually used COSCOS (i.e all caps) or coscos?

kian•9/27/23, 9:48 AM

Hmm.

kian•9/27/23, 9:48 AM

I might just be blind, but I don't see anything in workerd indicating that it even has the maths functions enabled.

Hey guys, I was wondering - is there any actual uptime or analytics for the D1 database? On the cloudflarestatus.com website, there's no status for D1 specifically but there are Workers and Durable Objects (I believe D1 is based on them). Is it safe to assume that D1 uptime is basically the same as DO/Workers?

Steved•9/27/23, 1:04 PM

SQLite is very loose on data types (by default), and won't complain if you put the wrong thing in a given column. To make it more strict you can use: https://www.sqlite.org/stricttables.html
And then on the date/times, you can get a more precise time (sub second) and a human readable ISO form with:

    createdAt DATETIME DEFAULT (strftime('%Y-%m-%dT%H:%M:%fZ', 'now'))

    createdAt DATETIME DEFAULT (strftime('%Y-%m-%dT%H:%M:%fZ', 'now'))

The DATETIME isn't a specific Sqlite datatype, but it distinguishes it from TEXT. Also if you're setting the value from Javascript, use the Date.toISOString().
More info on the SQLite handling of dates/times: https://www.sqlite.org/lang_datefunc.html

Theres no GA release date it will come eventually

Hello all, when I try to deploy/test my worker it says 'D1 bindings require module-format workers. [code: 10021]'. Could someone pls explain what this means? Am I missing a node module?
