It's technically possible, but SQLite (and other DBs) don't return it with the query results — your generated SQL could be large, and you may not want that coming back "by default" as it's a non-zero cost.

In other words: something we can look into! FWIW, PHP does this — you can call

$result->getSQL(true)

$result->getSQL(true)

— which asks SQLite to bind the params but doesn't run the query again.

That's good to know. PHP's approach seems reasonable! Would be a nice DX improvement. Thanks for the response.

I'm experiencing a likely bug, I'm not sure if anyone has encountered this or not. It happens on both live and local. Doing a simple SELECT on a DB of about 2MB is size, I randomly get

null

null

as the result, even though the queried item definitely exists. It doesn't happen if that is the only query that I run against the DB, but it happens as soon as realistic traffic is sent to wranger, and other tables and other types of queries happen at the same time.
Is this is a known issue?

Query:

wrangler d1 execute to run an SQL query, will this query be all in one db transaction, even if there are multiple udates, inserts and deletes in there?

To add to what Max said: this isn't a D1 thing, it's Object Destructuring in JS: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment

Destructuring assignment - JavaScript | MDN

The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.

Matt Silverlock•3/31/23, 12:53 PM

countResults

countResults

countResults

countResults isn't a property of

results

results

and so it'll always be undefined if it doesn't exist on the object.

Each destructured property can have a default value. The default value is used when the property is not present, or has value undefined. It is not used if the property has value null.
