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.

Of course. Let me know if that query works for you.

lokiwind•5/29/23, 4:50 PM

Yes, it worked. Thank you so much for helping me. @elithrar
I leave the code here, maybe someone needs it

export interface Env {
  DB: D1Database;
}

export default {
  async fetch(request: Request, env: Env) {
      const stmt = env.DB.prepare(`SELECT time FROM (SELECT time, count(*) as cnt FROM accesslog WHERE ip = ?1 GROUP BY time) WHERE cnt >= 3`).bind("81.213.254.29");
      const results = await stmt.all();
      return Response.json(results);
  },
};

It is healthier to write your codes with wrangler instead of using quick edit.

Hello again @elithrar
I am sharing a part of the code I wrote.facing an error, how can I fix it.Thanks in advance..

const results = await stmt.all();
        if (results.length > 0) {

const results = await stmt.all();
        if (results.length > 0) {

Error Response:
The 'length' property is not of type 'D1Result<unknown>'.

kian•5/29/23, 9:18 PM

all()all() returns a D1Result object

kian•5/29/23, 9:18 PM

you probably want it to be const { results } = await stmt.all();const { results } = await stmt.all(); to grab just the

results

results

property

kian•5/29/23, 9:18 PM

which is an array of returned rows

lokiwind•5/29/23, 9:20 PM

const { results } = await stmt.all();const { results } = await stmt.all();
Thanks for the help.
How can I query whether the result value is empty or not

kian•5/29/23, 9:20 PM

results

results

will be an empty array if there were no results, or

null

null

if it doesn't apply (that query doesn't return anything).

kian•5/29/23, 9:21 PM

Take a look at this

lokiwind•5/29/23, 9:21 PM

Oki, I'll look.

lokiwind•5/29/23, 9:33 PM

The solution: @kiannh thx

const { results } = await stmt.all();
    if (results && results.length > 0) {

const { results } = await stmt.all();
    if (results && results.length > 0) {

I have a billing question. If I have a table full of indexed images and I want to read one I know the index of how many read units would that use? Would it have to scan the whole table? Or would knowing the index just make it one read unit with the right query?

One for the index and one for the table row, as a generalization / not committal.

Have a 100k line SQL import I want to do.
Gets hung up on "Mapping SQL input into an array of statements"

Read that splitting into files with 5k lines helps.
Any tools to do this or should I just manually go through it?

Stronk•5/30/23, 12:53 AM

From my understanding that doesn't make sense. Aren't the read units based on how many 4 kB chunks you use when searching. So if the image is under 4 kilobytes including the index it should be one read if it doesn't have to scan the rest of the table right.

Matt SilverlockOP•5/30/23, 1:12 AM

Reading an index will likely always be an additional operation (read unit). We will make this clearer in the docs as we refine our pricing.

we are working on it. Won’t be within the next month. Focusing on Time Travel and stability.

Matt SilverlockOP•5/30/23, 1:17 AM

Keep in mind that you would need to serve 25 billion requests with that query pattern to exhaust the 50B included read units. 25B / 30 / 86400 = 9600+ requests/sec, 24/7/30.
