== Why is this an issue?
|
|
|
|
A `WHERE` clause condition that uses `NOT IN` with a subquery will have unexpected results if that subquery returns `NULL`. On the other hand `NOT EXISTS` subqueries work reliably under the same conditions.
|
|
|
|
This rule raises an issue when `NOT IN` is used with a subquery where the selected column is nullable.
