I've tried this. It says to use

--persist-to=/path/to/file

--persist-to=/path/to/file

to persist data to a specific location but no luck and on seeding I couldn't find any relevant info.

is there a way to run a one off typescript file that seeds the db? Before wrangler I was running a

prestart

prestart

script that runs a ts file to init local sqlite and seed it

vassbence•6/20/23, 8:32 PM

--persist-to is only a folder, so for example by using --persist-to=/temp the actual db file will be stored in /temp/v3/d1/x.sqlite

also you won't find the file right away, the db has to be accessed first for the file to be created

vassbence•6/20/23, 8:33 PM

file?

amorfati•6/20/23, 9:16 PM

Thank you for the help by the way

amorfati•6/20/23, 9:23 PM

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

amorfati•6/20/23, 9:23 PM

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

db

db

. Is there a way to change that by just changing

binding

binding

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

goodluck

betim•6/21/23, 9:49 AM

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?

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?
