DROP LOGFILE GROUPlogfile_group
ENGINE [=]engine_name
This statement drops the log file group named logfile_group
. The log
file group must already exist or an error results. (For information on creating log file groups, see Section
13.1.14, "CREATE LOGFILE GROUP
Syntax".)
Before dropping a log file group, you must drop all tablespaces that use that log file group for
UNDO
logging.
The required ENGINE
clause provides the name of the storage engine used by the log
file group to be dropped. Currently, the only permitted values for engine_name
are NDB
and NDBCLUSTER
.
DROP LOGFILE GROUP
is useful only with Disk Data storage for MySQL Cluster. See
Section 17.5.12, "MySQL Cluster Disk Data Tables".
