Description:
------------
Mysqli extension throws too many warnings.  For example, "SELECT * FROM table" results in a warning: "Warning: mysqli::query(): No index used in query/prepared statement SELECT * FROM table ..."  There's no way to have MySQL use an index when selecting all records, so this warning appears every time one wants to select all records from any table.  Sometimes Mysqli gives this warning even when MySQL is apparently using an index (i.e. the same query, 
executed with EXPLAIN, says it's using an index).

Mysqli should give warnings only on real problems.  Not using an index is at most worthy of a notice, not a warning, especially when there's no way to use an index with a particular query!

Use mysqli_report() to disable that.

yet in 2023 continue identical BUG:

simply execute the QUERY:

"SHOW FIELDS FROM `table`;"

then you will obtain [Fatal error. . .]
