MySQL Reference Manual for version 4.0.18.
C.6.8 Changes in release 3.21.26
-
FROM_DAYS(0) now returns "0000-00-00".
-
In
DATE_FORMAT(), PM and AM were swapped for hours 00 and 12.
-
Extended the default maximum key size to 256.
-
Fixed bug when using
BLOB/TEXT in GROUP BY with many
tables.
-
An
ENUM field that is not declared NOT NULL has NULL as
the default value.
(Previously, the default value was the first enumeration value.)
-
Fixed bug in the join optimizer code when using many part keys
on the same key:
INDEX (Organization,Surname(35),Initials(35)).
-
Added some tests to the table order optimizer to get some cases with
SELECT ... FROM many_tables much faster.
-
Added a retry loop around
accept() to possibly fix some problems on some
Linux machines.
