MySQL Reference Manual for version 4.0.18.
C.4.35 Changes in release 3.23.26 (18 Oct 2000)
-
Renamed
FLUSH MASTER and FLUSH SLAVE to RESET MASTER
and RESET SLAVE.
-
Fixed
<> to work properly with NULL.
-
Fixed a problem with
SUBSTRING_INDEX() and REPLACE().
(Patch by Alexander Igonitchev)
-
Fix
CREATE TEMPORARY TABLE IF NOT EXISTS not to produce an error
if the table exists.
-
If you don't create a
PRIMARY KEY in a BDB table, a hidden
PRIMARY KEY will be created.
-
Added read-only-key optimization to
BDB tables.
-
LEFT JOIN in some cases preferred a full table scan when there was
no WHERE clause.
-
When using
--log-slow-queries, don't count the time waiting for a lock.
-
Fixed bug in lock code on Windows which could cause the key cache
to report that the key file was crashed even if it was okay.
-
Automatic repair of
MyISAM tables if you start mysqld with
--myisam-recover.
-
Removed the
TYPE= keyword from CHECK and
REPAIR. Allow CHECK options to be combined. (You can still
use TYPE=, but this usage is deprecated.)
-
Fixed mutex bug in the binary replication log -- long update queries could
be read only in part by the slave if it did it at the wrong time, which
was not fatal, but resulted in a performance-degrading reconnect and
a scary message in the error log.
-
Changed the format of the binary log -- added magic number, server
version, binlog version. Added the server ID and query error code for each
query event.
-
Replication thread from the slave now will kill all the stale threads
from the same server.
-
Long replication usernames were not being handled properly.
-
Added
--replicate-rewrite-db option to mysqld.
-
Added
--skip-slave-start option to mysqld.
-
Updates that generated an error code (such as
INSERT INTO foo(some_key)
values (1),(1)) erroneously terminated the slave thread.
-
Added optimization of queries where
DISTINCT is used only on columns
from some of the tables.
-
Allow floating-point numbers where there is no sign after the exponent
(like
1e1).
-
SHOW GRANTS didn't always show all column grants.
-
Added
--default-extra-file=# option to all MySQL clients.
-
Columns referenced in
INSERT statements now are initialized properly.
-
UPDATE didn't always work when used with a range on a timestamp that
was part of the key that was used to find rows.
-
Fixed a bug in
FULLTEXT index when inserting a NULL column.
-
Changed to use
mkstemp() instead of tempnam(). Based
on a patch from John Jones.
