 Comments

---

The subset query was being re-written by the query optimizer and, in the process, the row value constructor expression was converted into an un-optimized expression, and this is where the issue occurred. The row value constructor comparisons in this case were not using the case-insensitivity of the comparison column's collation, resulting in less rows being returned than should have been returned.
