Correct. They removed the D1 shim in wrangler 3.5.0

Ahh thanks! I was checking this query

'SELECT * FROM content WHERE json_extract(data, "$.s") IN (0,1) AND json_extract(data, "$.t") IN (0) ORDER BY id DESC LIMIT 10 OFFSET 10'

'SELECT * FROM content WHERE json_extract(data, "$.s") IN (0,1) AND json_extract(data, "$.t") IN (0) ORDER BY id DESC LIMIT 10 OFFSET 10'

and it worked.

But if you add order byorder by end of the query, it does not work. Anyways, thanks again.

ive upgraded to 3.5.1, removed bindings, re-added, re-deployed still getting the same behavior:

__D1_BETA___D1_BETA_ is being added as a prefix in the environment, but not binding named DBDB

binding name: DB
env contains: __D1_BETA_DB

binding name: DB
env contains: __D1_BETA_DB

I tried to reference that variable __D1_BETA_DB__D1_BETA_DB, but it tells me that there is no function prepareprepare on it.

im expecting (and this was previous behavior) that a DBDB variable is hanging on the env that i can call prepare on. any ideas?

There is no support for downloading backups at this point. You don’t need to with Time Travel. https://developers.cloudflare.com/d1/learning/time-travel/

Thanks @rozenmd, does that mean a structure that makes use of the rich json querying may fare better than breaking more of the data into rows? For example, logging timestamps or user logins may be more affordable in a single text column in json format, then a table with rows marking timestamps?

The wrangler.toml config seems pretty straightforward:

[[d1_databases]]
  binding = "DB" # i.e. available in your Worker on env.DB
  database_name = "REDACTED"
  database_id = "REDACTED"

[[d1_databases]]
  binding = "DB" # i.e. available in your Worker on env.DB
  database_name = "REDACTED"
  database_id = "REDACTED"

Could someone help me sort this out?
