공개 프로퍼티들

프로퍼티	타입	설명
$check_tcp_responsiveness	boolean	Whether to check with fsockopen prior to mysql_connect.
$db_connections	array	The log of db connections made and the time each one took
$dbh	resource	The current mysql link resource
$dbh2host	array	Lookup array (dbhname => host:port)
$dbhs	array	Associative array (dbhname => dbh) for established mysql connections
$default_lag_threshold	integer	Maximum lag in seconds. Set null to disable. Requires callbacks.
$hyper_callbacks	array	Optional directory of callbacks to determine datasets from queries
$hyper_servers	array	The multi-dimensional array of datasets and servers
$hyper_tables	array	Optional directory of tables and their datasets
$last_found_rows_result	resource	After any SQL_CALC_FOUND_ROWS query, the query "SELECT FOUND_ROWS()" is sent and the mysql result resource stored here. The next query for FOUND_ROWS() will retrieve this. We do this to prevent any intervening queries from making FOUND_ROWS() inaccessible. You may prevent this by adding "NO_SELECT_FOUND_ROWS" in a comment.
$last_table	string	The last table that was queried
$last_used_server	array	The last server used and the database name selected
$max_connections	integer	The maximum number of db links to keep open. The least-recently used link will be closed when the number of links exceeds this.
$min_tries	integer	Minimum number of connections to try before bailing
$open_connections		The list of unclosed connections sorted by LRU
$persistent	boolean	Whether to use mysql_pconnect instead of mysql_connect
$save_backtrace		Whether to save debug_backtrace in save_query_callback. You may wish to disable this, e.g. when tracing out-of-memory problems.
$save_queries	boolean	Whether to store queries in an array. Useful for debugging and profiling.
$save_query_callback	callable	Custom callback to save debug info in $this->queries
$srtm	array	Otherwise it is an array of written tables.
$used_servers	array	Lookup array (dbhname => (server, db name) ) for re-selecting the db when a link is re-used.
