MySQL Reference Manual for version 4.0.18.
C.5.29 Changes in release 3.22.7 (Sep 1998: Beta)
-
Added
LIMIT clause for the DELETE statement.
-
You can now use the
/*! ... */ syntax to hide MySQL-specific
keywords when you write portable code. MySQL will parse the code
inside the comments as if the surrounding /*! and */ comment
characters didn't exist.
-
OPTIMIZE TABLE tbl_name can now be used to reclaim disk space
after many deletes. Currently, this uses ALTER TABLE to
regenerate the table, but in the future it will use an integrated
isamchk for more speed.
-
Upgraded
libtool to get the configure more portable.
-
Fixed slow
UPDATE and DELETE operations when using
DATETIME or DATE keys.
-
Changed optimizer to make it better at deciding when to do a full join
and when using keys.
-
You can now use
mysqladmin proc to display information about your own
threads. Only users with the PROCESS privilege can get
information about all threads.
(In 4.0.2, you need the SUPER privilege for this.)
-
Added handling of formats
YYMMDD, YYYYMMDD,
YYMMDDHHMMSS for numbers when using DATETIME and
TIMESTAMP types. (Formerly these formats only worked with strings.)
-
Added connect option
CLIENT_IGNORE_SPACE to allow use of spaces
after function names and before `(' (Powerbuilder requires this).
This will make all function names reserved words.
-
Added the
--log-long-format option to mysqld to enable timestamps
and INSERT_IDs in the update log.
-
Added
--where option to mysqldump (patch by Jim Faucette).
-
The lexical analyzer now uses "perfect hashing" for faster parsing of SQL
statements.
