is it possible to tell wrangler to use a specific name.sqlitename.sqlite file?

amorfati•6/20/23, 9:16 PM

Thank you for the help by the way

that can run a ts file and pass it the context with the database client? I will try that

when I created a new local db just now, it said binding is

. Is there a way to change that by just changing bindingbinding in wrangler config?

Dahoom•6/20/23, 10:57 PM

use the --local option

Dahoom•6/20/23, 10:58 PM

so something like wrangler d1 execute --local --comand="SELECT NOTHING"wrangler d1 execute --local --comand="SELECT NOTHING"

DDahoom so something like ``wrangler d1 execute --local --comand="SELECT NOTHING"``

Dahoom•6/20/23, 10:58 PM

Dahoom•6/20/23, 11:04 PM

you can use wrangler

Dahoom•6/20/23, 11:04 PM

i tested it and it works in my pages directory

Dahoom•6/20/23, 11:05 PM

even when running wrangler pages dev it will read the wrangler.toml file and load the DB inside it

any way to create a DB with the regular backend alongside another with the experimental backend, locally? some of our queries don't work with the experimental backend (after importing data from our existing DBs that use the regular backend) and wanted to debug locally..

betim•6/21/23, 9:50 AM

this is using wrangler 3.1.0

Original message was deleted

betim•6/21/23, 9:57 AM

I was afraid that'd be the answer.. any guidance on figuring out why the experimental backend doesn't like our queries? any high level differences in SQLite support between regular and experimental backend that I should be aware of?

I suppose I'm wondering what SQLite differences would account for this seeing that the query works in the regular backend but errors out in the experimental?

betim•6/21/23, 10:04 AM

yup, all good on this front.. everything is within the limits on the query and data side

betim•6/21/23, 10:05 AM

is there a version difference in the underlying sqlite runtime between regular and experimental backend? wondering if the query parsing/execution happens differently in the (I'm suspecting) newer version of sqlite that the experimental backend uses..

kian•6/21/23, 10:07 AM

The experimental backend has SQLITE_LIMIT_COMPOUND_SELECTSQLITE_LIMIT_COMPOUND_SELECT set to 33

betim•6/21/23, 10:08 AM

does the backend support modifying that at either creation-time or runtime?

Max (@rozenmd)•6/21/23, 10:08 AM

that'll be why

betim•6/21/23, 10:08 AM

I think our query needs 5

Matt SilverlockOP•6/21/23, 10:13 AM

Not adjustable: we’re likely to just increase it. A minimal sample query that fails now, but would work at (e.g.) 5 would be great.
