Does kysely convert Table names lowercase when it's building a query ?

When I try to run this code it tries to insert into "profile" table not "Profile": Note: I have only extracted important parts

// Kysely codegen output
export interface Profile {
  profile_id: Generated<number>;
  username: string | null;
  created_at: Generated<Date | null>;
  updated_at: Generated<Date | null>;
  user_id: string | null;
}

// types
type ProfileTable = KeysToCamelCase<Profile>

export type SelectableProfile = Selectable<ProfileTable>
export type InsertableProfile = Insertable<ProfileTable>
export type UpdateableProfile = Updateable<ProfileTable>

export type DB = {
  Profile: ProfileTable
}

// connection
export const db = new Kysely<DB>({
  dialect: new PlanetScaleDialect({
    host: DATABASE_HOST,
    username: DATABASE_USERNAME,
    password: DATABASE_PASSWORD
  }),
  plugins: [new CamelCasePlugin()]
})


// repo
export async function createProfile(data: InsertableProfile) {
  try {
    const response = await db
      .insertInto("Profile")
      .values(data)
      .executeTakeFirst()
    return response
  } catch (e) {
    log.error(e, "Couldn't create profile")
    return null
  }
}

// Kysely codegen output
export interface Profile {
  profile_id: Generated<number>;
  username: string | null;
  created_at: Generated<Date | null>;
  updated_at: Generated<Date | null>;
  user_id: string | null;
}

// types
type ProfileTable = KeysToCamelCase<Profile>

export type SelectableProfile = Selectable<ProfileTable>
export type InsertableProfile = Insertable<ProfileTable>
export type UpdateableProfile = Updateable<ProfileTable>

export type DB = {
  Profile: ProfileTable
}

// connection
export const db = new Kysely<DB>({
  dialect: new PlanetScaleDialect({
    host: DATABASE_HOST,
    username: DATABASE_USERNAME,
    password: DATABASE_PASSWORD
  }),
  plugins: [new CamelCasePlugin()]
})


// repo
export async function createProfile(data: InsertableProfile) {
  try {
    const response = await db
      .insertInto("Profile")
      .values(data)
      .executeTakeFirst()
    return response
  } catch (e) {
    log.error(e, "Couldn't create profile")
    return null
  }
}

You're using the CamelCasePlugin, so yes it does in this case. As it should.

As far as I can see from the docs https://kysely-org.github.io/kysely/interfaces/CamelCasePluginOptions.html there is no configuration option for keeping table name as it's but camelcasing the column names. Is there a way I can achieve this ?

Not currently, but we could probably add it easily. Could you open an issue in github?
