Cursors are just queries with a limit You'll have to keep track of the last seen ID, because that'll need to provide in subsecuent queries to get the next batch of results for example:

const cursorUsers = db
  .select()
  .from(users)
  .where(and([
    sql`1=1`,
    cursorId ? gt(users.id, cursorId) : undefined. // <-- If cursorId is provided, get all the users with a id higher than that
  ]))
  .limit(10)

const cursorId = cursorUsers.at(-1).id  <-- this would be the last id seen from the query

const cursorUsers = db
  .select()
  .from(users)
  .where(and([
    sql`1=1`,
    cursorId ? gt(users.id, cursorId) : undefined. // <-- If cursorId is provided, get all the users with a id higher than that
  ]))
  .limit(10)

const cursorId = cursorUsers.at(-1).id  <-- this would be the last id seen from the query
