All errors should (will) be thrown. An empty result set isn’t an error though, but

D1Result

D1Result will have no rows

You should handle the false case - let me take an action to iterate over the failure modes more explicitly

looks like a wrangler bug, not seeing us exit with code 1: https://github.com/cloudflare/workers-sdk/blob/main/packages/wrangler/src/d1/migrations/apply.tsx

can you file an issue on the wrangler repo?

That issue was opened before D1 was even in open alpha, which was probably… a little premature

(We’re close with the Prisma folks so expect something soon)

There is 1 table and only 4 ip addresses are registered in this table.
Showing 65kb data.
What's the reason for that?

Jason Hostetter•5/29/23, 11:33 AM

Ok, it’s not obvious to me how to calculate expression depth- the query that’s producing this error has two nested CTEs, the inner CTE has a single sub query. So it seems like only three layers of depth with the rest a bunch of joins? I’m clearly missing something about how depth is calculated.

Hello, I have a code snippet where I list the entries of an ip address:

export interface Env {
    DB: D1Database;

export default {
    async fetch(request: Request, env: Env) {
        const stmt = env.DB.prepare('SELECT time FROM accesslog WHERE ip = ?1').bind("81.213.254.29");
        const results = await stmt.all();
        return Response.json(results);
    },
};

export interface Env {
    DB: D1Database;
}

export default {
    async fetch(request: Request, env: Env) {
        const stmt = env.DB.prepare('SELECT time FROM accesslog WHERE ip = ?1').bind("81.213.254.29");
        const results = await stmt.all();
        return Response.json(results);
    },
};

My question is: How can I determine if there are 3 of the same data?
There are 3 of the data 13:43:44 in the code response.
I want to perform an operation when there are 3 of the same data.
How do I detect this with workers

Matt Silverlock•5/29/23, 3:35 PM

You can do it in SQL -

SELECT DISTINCT time FROM …

SELECT DISTINCT time FROM …

SELECT DISTINCT time FROM …

SELECT DISTINCT time FROM …

DISTINCT is an exact match.

f you want to match on a less precise time - such as minute granularity - then use time functions to format as HH:MM before you use

DISTINCT

DISTINCT

I misread your question — and I will make it clear that you don’t need to get snarky when folks are trying to help you.

SELECT time FROM (SELECT time, count(*) as cnt FROM accesslog WHERE ip = ?1 GROUP BY time) WHERE cnt = 3

SELECT time FROM (SELECT time, count(*) as cnt FROM accesslog WHERE ip = ?1 GROUP BY time) WHERE cnt = 3

SELECT time FROM (SELECT time, count(*) as cnt FROM accesslog WHERE ip = ?1 GROUP BY time) WHERE cnt = 3

SELECT time FROM (SELECT time, count(*) as cnt FROM accesslog WHERE ip = ?1 GROUP BY time) WHERE cnt = 3 will give you want you want. Get a count of all occurrences of each time entry in a sub query and then filter for 3.
