# X_QUERY_NOT_PAGEABLE

## Means

a read returned rows with no id, so a cursor cannot name a position

## Typical cause

a projection or aggregate that drops the primary key — the id is the tiebreak that makes the sort order total

## Fix

return the key from the query's `sql:`, e.g. `db.posts.select({ id: true, … })`
