Escaped paramaters in raw sql
For a few queries I made postgreSQL functions, this is the current way of how I call this function:
``ts
export async function getRandomAnswerByQuestionId({ questionId, answerLimit }: { questionId: string, answerLimit: number }) {
return sqlSELECT * FROM get_random_answers(${sql.val(questionId)}, ${sql.val(answerLimit)})`.execute(databaseClient);
}...Solution:
That's fine, but you don't even need to use
sql.val in this case

Declaring types under 'kysely-codegen' module
Hey everyone, because I'm using Prisma to push schemas to my database (it's because my Zod Schemas) also getting generated from my Prisma schemas -- it's why I'm still using it incase you're wondering why I'm in this situation:
I have a
./types/kysely-codegen.d.ts file which contains ```ts
import { Insertable, Selectable, Updateable } from 'kysely';
import { User } from 'kysely-codegen';...From Prisma Model to Kysely Schema
Hey everyone, I'm using this package https://github.com/valtyr/prisma-kysely, the output of this Prisma Model ```ts

[ERR_UNKNOWN_FILE_EXTENSION] when running migrations
I have a project with Sveltekit, TypeScript, and Kysely with SQLite. When I run my migrations, using the FileMigrationProvider, I get the following error:
```
TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for /Users/crummy/code/finances/src/db/migrations/2023-06-22-initial.ts
at new NodeError (node:internal/errors:399:5)
at Object.getFileProtocolModuleFormat [as file:] (node:internal/modules/esm/get_format:79:11)...
Solution:
I got it working by avoiding FileMigrationProvider. Kind of hacky, not sure if there's a better way to do these imports:

Figuring out where in codebase an exception originated from
Hi all,
This might be a stupid question, but what is the best way to figure out which
.execute() call threw a SQL exception? I know ideally I should be doing error handling on each call, but I have a large codebase and I'm not sure where this error is coming from. Is there any easy way of figuring this out? Maybe a way to have a wrapper that prints out the query if malformed, or to print out the stack trace where the original call was executed?

I realize I could write the raw sql, however I was curious how I would go about creating the following insert statement using kysely.

Triggers vs stored procedures
Hey everyone, I don't think this is related to Kysely directly, so excuse me but this is the only SQL type of server I am in. I am wondering what is the best way to automatically update a table attribute based on when another attribute changes (in the same table or another table). For example, if I want to have the attributes
updatedAt and lastLogin updated on their own from the Model below ```ts
model User {
id Int @id @default(autoincrement())
createdAt DateTime @default(now()) @db.Date
updatedAt DateTime @db.Timestamp() ...`Selectable`, `Insertable` and `Updateable` wrappers
Hey everyone, I am using this package: https://github.com/valtyr/prisma-kysely and I noticed that the output file does not include

export type NewPerson = Insertable<PersonTable>
export type EditedPerson = Updateable<PersonTable>
export type Person = Selectable<PersonTable>
export type NewPerson = Insertable<PersonTable>
export type EditedPerson = Updateable<PersonTable>

Using jsonArrayFrom with mariadb.
Hello,
Madiadb does not have cast to JSON, and cannot reference nested subqueries.

There are a few approaches:

2. withSchema method to apply to specific queries on the fly....
Limit with a literal value
Hi folks, thanks for all your work on Kysely, it's great!
I'm wondering how I can add a limit clause with a literal value, rather than a parameter.
I have a strange use case, I'm querying a https://materialize.com/ database, which presents as postgres, but has different features. It also has some limitations, one of which is limit must be a literal value, not an expression or parameter. ...
Prisma-kysely generator converts boolean to a number
Hi, so using
prisma-kysely, the generated type for a prisma Bool appears to be a number for some reason. Is this correct?Solution:

Is there a way to not have as many Selectable<> generics?
Hi. I'm using
prisma-kysely to generate my Kysely types, and it generates them with the Generated generic. I therefore need to use the Selectable generic to change it to the return type of what is selected when I want to use the type. Is there a way to avoid using it so often?insertId return by transaction
the insertId returned by a transaction is of the last executed query, right?
How can I use Kysely migration inside NextJS 13 project?
