Description
Note

mysql_refresh() is deprecated and will be removed in a future version of MySQL. Instead, use mysql_query() to execute a FLUSH statement.

This function flushes tables or caches, or resets replication server information. The connected user must have the RELOAD privilege.

The options argument is a bitmask composed from any combination of the following values. Multiple values can be OR'ed together to perform multiple operations with a single call.

  • REFRESH_GRANT

    Refresh the grant tables, like FLUSH PRIVILEGES.

  • REFRESH_LOG

    Flush the logs, like FLUSH LOGS.

  • REFRESH_TABLES

    Flush the table cache, like FLUSH TABLES.

  • REFRESH_HOSTS

    Flush the host cache, like FLUSH HOSTS.

  • REFRESH_STATUS

    Reset status variables, like FLUSH STATUS.

  • REFRESH_THREADS

    Flush the thread cache.

  • REFRESH_SLAVE

    On a slave replication server, reset the master server information and restart the slave, like RESET SLAVE.

  • REFRESH_MASTER

    On a master replication server, remove the binary log files listed in the binary log index and truncate the index file, like RESET MASTER.
