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) {

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

K

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

K

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

K

kian•5/29/23, 9:20 PM

results

results

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

null

null

null

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

The solution: @kiannh thx

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

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

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

const { results } = await stmt.all();

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?

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.

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.

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.

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 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.
