myisamchk
Other actions that myisamchk
can do, besides repair and check tables:
-a or --analyze
myisamchk --describe --verbose table_name'
or using SHOW KEYS
in
MySQL.
-d or --description
-A or --set-auto-increment[=value]
AUTO_INCREMENT
to start at this or higher value. If no value is
given, then sets the next AUTO_INCREMENT
value to the highest used value
for the auto key + 1.
-S or --sort-index
-R or --sort-records=#
SELECT
and ORDER BY
operations on
this index. (It may be very slow to do a sort the first time!)
To find out a table's index numbers, use SHOW INDEX
, which shows a
table's indexes in the same order that myisamchk
sees them. Indexes are
numbered beginning with 1.
