== Why is this an issue?

``++SQL COUNT(..), MIN(..), MAX(..), SUM(..), AVG(..)++`` aggregate functions cause the SAP table buffer to be bypassed, so the use of these functions can lead to performance issues.


=== Noncompliant code example

[source,abap]
----
SELECT COUNT(*) 
       FROM persons 
       INTO count 
       WHERE city = 'NEW YORK'.
