== 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.
|
||
|
||
|
||
*Noteworthy*
|
||
|
||
This rule raises issues only when a *Data Dictionary* is provided during the analysis. See https://docs.sonarqube.org/latest/analysis/languages/plsql/
