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 resultsresults property

kian•5/29/23, 9:18 PM

which is an array of returned rows

lokiwindOP•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

resultsresults 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

lokiwindOP•5/29/23, 9:21 PM

Oki, I'll look.

lokiwindOP•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 Silverlock•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.

Stronk•5/30/23, 1:12 AM

Cool

Stronk•5/30/23, 1:13 AM

Is there a way I can test how a lookup would be counted during this time?

Matt Silverlock•5/30/23, 1:15 AM

Not yet, per the docs: https://developers.cloudflare.com/d1/platform/pricing/

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

Pricing · Cloudflare D1 docs

While in public Alpha, D1 is currently free to use on all Workers plans. Refer to the our recent announcement) for more information.

Matt Silverlock•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.

We're planning on removing the "Mapping SQL input into an array of statements" step from wrangler fwiw

Cconnor hopefully it gets merged soonish :)

Matt Silverlock•5/30/23, 5:16 PM

We’re looking at alternatives that make it easier to interleave SQL and JS. We can’t give you a specific timeline. The blog highlights what we are focusing on in the near term for D1.

Max (@rozenmd)•5/30/23, 6:43 PM

i think we borrowed that from the cf v4 api

Anyone else getting this when trying to use the experimental backend for new D1 databases?

Any expectation on how long that'll take to make it in? Curious if I should roll back to my old DB and write batching functions instead (which is why I was trying a move to the new backend).

itsmatteomanf•5/30/23, 8:12 PM

Any specific reasoning why

CURRENT_TIMESTAMP

CURRENT_TIMESTAMP

works when using it as the default for a column in the schema, but fails when used in any kind of statement (with a "not authorized")?

itsmatteomanf•5/30/23, 8:14 PM

To note, a

datetime('now')

datetime('now')

works fine in the statement.
