Dynamic conditional raw query question

Hello there, Im trying to create a dynamic query like this:

 await sql`SELECT
  column AS "data"
FROM my_table 
${type ? ` WHERE type = ${type}` : ''};`.execute(client);

 await sql`SELECT
  column AS "data"
FROM my_table 
${type ? ` WHERE type = ${type}` : ''};`.execute(client);

But kysely is trying to do substitution where I have my TS logic to either add the WHERE clause or not. How can I fix this ?

Skip the questions of why im using a string query vs the query builder, this is a once off raw query to tables I don't have the schema for. 😆

You can use Kysely<any> to write that query. Just cast any db instance

const anyDb: Kysely<any> = db

const anyDb: Kysely<any> = db

But this also works

await sql`SELECT
  column AS "data"
FROM my_table 
  ${type ? sql`WHERE type = ${type}` : sql``};
`.execute(client);

await sql`SELECT
  column AS "data"
FROM my_table 
  ${type ? sql`WHERE type = ${type}` : sql``};
`.execute(client);

sql.raw is not safe when there's user input involved.
