+    Be cautious when using ``sql_affectedrows()`` to determine the number of rows affected by your query, especially with **SELECT** queries.
+    This function's behavior can differ depending on the used database driver and whether the query was cached.
+
+    Do not rely solely on ``sql_affectedrows()`` to confirm the number of impacted rows. Consider alternative approaches
+    like checking the number of rows returned by `sql_fetchrow`_ or `sql_fetchrowset`_.
