MySQL Reference Manual for version 4.0.18.
C.4.56 Changes in release 3.23.5 (20 Oct 1999)
-
Fixed some Y2K problems in the new date handling in 3.23.
-
Fixed problem with
SELECT DISTINCT ... ORDER BY RAND().
-
Added patches by Sergei A. Golubchik for text searching on the
MyISAM
level.
-
Fixed cache overflow problem when using full joins without keys.
-
Fixed some configure issues.
-
Some small changes to make parsing faster.
-
Adding a column after the last field with
ALTER TABLE didn't work.
-
Fixed problem when using an
AUTO_INCREMENT column in two keys
-
With
MyISAM, you now can have an AUTO_INCREMENT column as a key
sub part:
CREATE TABLE foo (a INT NOT NULL AUTO_INCREMENT, b CHAR(5), PRIMARY KEY (b,a))
-
Fixed bug in
MyISAM with packed char keys that could be NULL.
-
AS on field name with CREATE TABLE table_name SELECT ... didn't
work.
-
Allow use of
NATIONAL and NCHAR when defining character columns.
This is the same as not using BINARY.
-
Don't allow
NULL columns in a PRIMARY KEY (only in UNIQUE
keys).
-
Clear
LAST_INSERT_ID() if one uses this in ODBC:
WHERE auto_increment_column IS NULL. This seems to fix some problems
with Access.
-
SET SQL_AUTO_IS_NULL=0|1 now turns on/off the handling of
searching after the last inserted row with WHERE
auto_increment_column IS NULL.
-
Added new variable
concurrency to mysqld for Solaris.
-
Added
--relative option to mysqladmin to make
extended-status more useful to monitor changes.
-
Fixed bug when using
COUNT(DISTINCT ...) on an empty table.
-
Added support for the Chinese character set GBK.
-
Fixed problem with
LOAD DATA INFILE and BLOB columns.
-
Added bit operator
~ (negation).
-
Fixed problem with UDF functions.
