mysqlnd.log_mask = "0", which disables logging.

It is possible to add the values together, to log multiple query
|
||||
types. For example, you can set it to 16 + 32 = 48 to log slow
|
||||
queries which either use no good index
|
||||
(SERVER_QUERY_NO_GOOD_INDEX_USED = 16) or no index at all
|
||||
(SERVER_QUERY_NO_INDEX_USED = 32).

||||
</para>

<para>
|
||||
Note, the SERVER_* constants are MySQL internal (C-level)
|
||||
constants, not exported to the PHP userland. There are no
|
||||
corresponding PHP constants. However, you can look up the values
|
||||
in the table which has been created by inspecting the MySQL Native
|
||||
Driver source.
