Yeah, that’s the way. There is sort of a way to do globals, but it shouldn’t give you much of a benefit since Drizzle itself is stateless
Sokay good to know thanks!
SActually managed to migrate an entire app fairly quick. everything working with some hacks.
Even tho i gotta rewrite my transactions :/

im in love with the cloudflare services but d1 seems to be the biggest headache for a lot of people

Describe the solution Has the procedures feature mentioned in this article been shipped? This feature does not seem to be available in the current version sdk, either locally or remotely. Is there ...
BDoes D1 support positional parameter binding like ?1 ?2 instead of ? ?
BYes, but
await DB.prepare('SELECT col FROM table WHERE col1 = ?2 AND col2 = ?1 AND col3 = ?1').bind(1, 2).run()
II just noticed that
SELECT file_id FROM file WHERE ref_id = '123' shows "rows_read": 2. Does it mean that reading index is also counted as well as reading the data?
ICorrect.
B@Isaac McFadyen any idea why none of
npx wrangler d1 migrations --help / npx wrangler d1 migrations apply --help lists persist-to as a valid option?
IFrom the source it looks like a valid option so I'm guessing it might have just been forgotten in the 
--help output? INot quite sure, I haven't used migrations much, sorry.
SHello, I have a website project where I'm trying to use a D1 db. However, I'm getting big latencies, so I was thinking of using the Sessions API. However, I'm afraid of data inconsistency (for reads) from one user to the next. Can help me understand how should a session be initiated on a worker to ensure that all future queries have up-to-date data? Like, should navigating between pages create a new session to have up-to-date info? That feels as bad as using no replication. Any insights on if I missed something? Thanks a lot 
JThe sessions API doesn’t exist yet - but soon. I’m sure a lot more info will be shared when it’s released and generally available, with best practices, recommendations, etc.
Sokay thank you
MIs this already available? I’m not sure if anyone can use D1 for a serious project in EU until we have this
LReplication is not released yet, and will be optional anyway for some time. You can decide to keep your primary database instance in EEUR or WEUR.
Mis keeping data in EU done using location hint? Because docs say that one is not binding and might even be ignored.
Also is there any way to prevent this replication? Like when does that happen? If for anyone outside of an specific region no DB access happens, does that mean no replication is happening either?

OEU GDPR jurisdiction support is something I'm also interested in
LAlso is there any way to prevent this replication? Like when does that happen? If for anyone outside of an specific region no DB access happens, does that mean no replication is happening either?There is no replication at the moment. Once it's out, we will have some control for jurisdictions once those are added for D1.
You can also check where your database is located after creation to confirm its location.
Mwould you mind pointing me where the location of a DB can be seen? not finding anything on dashboard
Mfound it using wrangler 
LWrangler can give it to you yes, your query responses also contain that information in the
meta object, and the dashboard will show it soon as well.MThanks again. For now need to provide the hint and chk location afterwards. Would be nice if in future that hint is more binding too.
HIf you are referring to DOs, they do support Jurisdictions, which means it isn’t a hint, but a guarantee that they run in a given region
CDoes D1 provides some proper error codes?
so far I'm doing:
but seems super hacky

RHello, is there any plan to create an official driver to manage D1 databases via third-party database managers like DBeaver?
PHi All. I'm working with the D1 Database by using the Prisma, Wrangler in the NextJS App Router Fullstack. I have a problem when I need to get the env to bind it into the Prisma D1 Adapter. Does anyone have experience with that? Could you help me with this? Thanks all
HYes, it is Durable Objects. D1 Databases are Durable Objects with some utils to make it easy to query externally
HDurable Objects do support Jurisdictions, which force the location. Not sure whether D1 will have the same(don’t think it exists yet)
CIm sure someone has asked this before but I couldn't find anything about it. The D1 free tier says there are 25 billion rows read per month included. Does this only count the rows that the query returns? Or does it count rows that were checked and not returned as well?
LOr does it count rows that were checked and not returned as well?All rows read are counted. From indices, non-indices, views, etc.
COk
1D1 Free tier is 5million row reads per day, not 25bil per month. 25bil is included in the $5 Workers Paid plan
DI know that during a D1 export the database is unavailable for other requests (https://developers.cloudflare.com/d1/best-practices/import-export-data/#known-limitations).
A couple of questions on this:
A couple of questions on this:
- What's a reasonable maximum time for an export to take? If a database hits the 10gb limit, how long would exporting it take?
- Will this limitation go away when read only replicas become available?
YWhere can I request to update the error message for D1 response errors?
L- This really depends on each database. How many millions of rows, how big each row is, etc.
- Probably reads could still flow through with the replicas, but the primary will still be blocked. We have some work streams to improve the import/export APIs over the next few months.
1Replicas that don't exist publicly yet right?
DOn 1, makes sense. Can you give any guidance on the possible ranges of times the db might be blocked? Seconds, 10 minutes, 30 minutes?
DIs it possible to export a backup from Time Travel? Snapshots must be on disk somewhere?
RHello, I think this message has gone unnoticed among others. Is there any plan to collaborate with an existing database manager to support d1?
Spretty sure drizzle studio works?
BYou can use Outerbase to view your D1 databases
MHi my d1 all of a sudden went from less than 10m rows read to over 38B in 5 days.
I didn't make any change and still uses the same data, not sure what's causing it.
It keeps on increasing, is there any way I can fix this. Please

IDouble-check that whatever Worker is querying the D1 DB isn't getting flooded with requests, perhaps?
IAnd/or that you haven't accidentally leaked an access token that someone's using to hit the API
MThis is the query that is being shown in the metrics with the higest count, multiples of it. And that query is only found in my cloudflare pages.
is there any way I can check to see where the D1 queries are coming from aside that, or a way to fix it, it's been that query for months with no issues

MI found the query already, using the d1 insights wrangler, thank you!
XHi, I'm using Cloudflare D1 with Drizzle ORM and want to batch multiple queries in a single transaction. However, I need
Thanks in advance! :)
newUser.id and account.id from the first two queries to use in the third one. Since the queries are in an array, I can't assign these values to a constant. Is there a way to achieve this within a single batch, or do I need to split it into two?Thanks in advance! :)
