prepared statements placeholder typing

Schema

const users = sqliteTable("user", {
  id: text("id").primaryKey(),
  text: text("text"),
})

const users = sqliteTable("user", {
  id: text("id").primaryKey(),
  text: text("text"),
})

const updateUser = db
  .update(users)
  .set({ text: sql.placeholder("text") })
  .where(eq(users.id, sql.placeholder("id")))
  .prepare()

const updateUser = db
  .update(users)
  .set({ text: sql.placeholder("text") })
  .where(eq(users.id, sql.placeholder("id")))
  .prepare()

On the text property I get the following

Type 'Placeholder<"text", any>' is not assignable to type 'string | SQL<unknown> | null | undefined'.

Type 'Placeholder<"text", any>' is not assignable to type 'string | SQL<unknown> | null | undefined'.

The issue only seems to occur in the set part, is there a reason? A better way?

Not sure if this will fix it or not, but try this:

const updateUser = db
  .update(users)
  .set({ text: sql.placeholder("text").getSQL() })
  .where(eq(users.id, sql.placeholder("id")))
  .prepare()

const updateUser = db
  .update(users)
  .set({ text: sql.placeholder("text").getSQL() })
  .where(eq(users.id, sql.placeholder("id")))
  .prepare()

What's this? Can't seem to find any documentation It seems to work

It's not documented (like a lot of things), but I noticed placeholder had a .getSQL() method that returned an SQL object https://github.com/drizzle-team/drizzle-orm/blob/76eb060acf4829fc25189efb57a11a1408fd1e15/drizzle-orm/src/sql/sql.ts#L539
