strange mysqli index errors

[neoform]

When i set mysqli to report:

mysqli_report(MYSQLI_REPORT_INDEX);

 

for whatever reason when i do this query:

"SELECT name FROM system_permissions"

(it's a small table and i want all the permissions selected; the table has a primary key 'id')

 

I get this error:

Warning: mysqli::query() [function.mysqli-query]: (00000/0): No index used in query/prepared statement SELECT name FROM system_permissions in common.php on line 30

 

I don't get why either, since the query runs perfectly in mysql without any warnings.. so why is php giving me this error?
