This will fail, as the sqlite dialect uses BEGIN/COMMIT, which are not allowed on DO sqlite.

I'm curious why the sqlite dialect migrate function doesn't use transactions within... but I haven't spent any time looking into it. I assume there might be a legitimate reason I'm just not seeing.

This will also fail. To do transactions, you have to use a function which is (so far) only documented on Discord:
this.ctx.storage.transactionSync(() => {...})

Thanks @zwily! I hadn't gotten round to testing transactions yet. I've tested this API and it works perfectly. I also checked that it can be nested, and that works perfectly as well.

Savepoints also don't work. Have to use the API above.

Cool - I updated my test app at https://github.com/zwily/test-drizzle-durable-objects to use the new migrate method. |

Hi @jmshal, great work so far! What is the current state of this? Do you need any help moving this forward? I'm currently also working with the Workers DO SQL API and doing everything "by hand", which is quite unsustainable ^^ |

Hi @constantins2001. When I left this - it was all working, minus migrations. I've asked for comments about how that should work. I have ideas, but other than tweeting generally about supporting DO SQLite if they got enough likes, the official Drizzle team has not shown any interest in this PR or issue. I'm happy to work on this issue further, but I don't want to waste any time if existing maintainers/the Drizzle team don't agree with the direction it takes. |
This PR adds initial support for the SQLite capabilities in Cloudflare Durable Objects.
See #3052 for more info.
This is my first contribution to Drizzle - so any pointers are much appreciated. Unfortunately I have limited time right now, but I can see what I can do.
