MySQL Reference Manual for version 4.0.18.
C.4.38 Changes in release 3.23.23 (01 Sep 2000)
-
Changed sort order for 'German'; all tables created with 'German' sortorder
must be repaired with
REPAIR TABLE
or myisamchk
before use!
-
Added
--core-file
option to mysqld
to get a core file on
Linux if mysqld
dies on the SIGSEGV
signal.
-
MySQL client
mysql
now starts with option
--no-named-commands
(-g
) by default. This option can be
disabled with --enable-named-commands
(-G
). This may cause
incompatibility problems in some cases, for example, in SQL scripts that
use named commands without a semicolon, etc.! Long format commands
still work from the first line.
-
Fixed a problem when using many pending
DROP TABLE
statements at
the same time.
-
Optimizer didn't use keys properly when using
LEFT JOIN
on an
empty table.
-
Added shorter help text when invoking
mysqld
with incorrect options.
-
Fixed non-fatal
free()
bug in mysqlimport
.
-
Fixed bug in
MyISAM
index handling of
DECIMAL
/NUMERIC
keys.
-
Fixed a bug in concurrent insert in
MyISAM
tables. In some contexts,
usage of MIN(key_part)
or MAX(key_part)
returned an empty set.
-
Updated
mysqlhotcopy
to use the new FLUSH TABLES table_list
syntax. Only tables which are being backed up are flushed now.
-
Changed behavior of
--enable-thread-safe-client
so
that both non-threaded (-lmysqlclient
) and threaded
(-lmysqlclient_r
) libraries are built. Users who linked
against a threaded -lmysqlclient
will need to link against
-lmysqlclient_r
now.
-
Added atomic
RENAME TABLE
command.
-
Don't count
NULL
values in COUNT(DISTINCT ...)
.
-
Changed
ALTER TABLE
, LOAD DATA INFILE
on empty tables and
INSERT ... SELECT ...
on empty tables to create non-unique indexes
in a separate batch with sorting. This will make the above calls much
faster when you have many indexes.
-
ALTER TABLE
now logs the first used insert_id correctly.
-
Fixed crash when adding a default value to a
BLOB
column.
-
Fixed a bug with
DATE_ADD/DATE_SUB
where it returned a datetime instead
of a date.
-
Fixed a problem with the thread cache which made some threads show up as
***DEAD***
in SHOW PROCESSLIST
.
-
Fixed a lock in our thr_rwlock code, which could make selects that run
at the same time as concurrent inserts crash. This only affects systems
that don't have the
pthread_rwlock_rdlock
code.
-
When deleting rows with a non-unique key in a
HEAP
table, all rows
weren't always deleted.
-
Fixed bug in range optimizer for
HEAP
tables for searches on a part
index.
-
Fixed
SELECT
on part keys to work with BDB
tables.
-
Fixed
INSERT INTO bdb_table ... SELECT
to work with BDB
tables.
-
CHECK TABLE
now updates key statistics for the table.
-
ANALYZE TABLE
will now only update tables that have been changed
since the last ANALYZE
. Note that this is a new feature and tables
will not be marked to be analysed until they are updated in any way with
3.23.23 or newer. For older tables, you have to do CHECK TABLE
to update the key distribution.
-
Fixed some minor privilege problems with
CHECK
, ANALYZE
,
REPAIR
and SHOW CREATE
commands.
-
Added
CHANGE MASTER TO
statement.
-
Added
FAST
, QUICK
EXTENDED
check types to
CHECK TABLES
.
-
Changed
myisamchk
so that --fast
and
--check-only-changed
are also honored with --sort-index
and
--analyze
.
-
Fixed fatal bug in
LOAD TABLE FROM MASTER
that did not lock the
table during index re-build.
-
LOAD DATA INFILE
broke replication if the database was excluded
from replication.
-
More variables in
SHOW SLAVE STATUS
and SHOW MASTER STATUS
.
-
SLAVE STOP
now will not return until the slave thread actually exits.
-
Full-text search via the
MATCH()
function and FULLTEXT
index type
(for MyISAM
files). This makes FULLTEXT
a reserved word.
