MySQL Reference Manual for version 4.0.18.
C.6.18 Changes in release 3.21.17
-
Changed documentation string of
--with-unix-socket-path
to avoid
confusion.
-
Added ODBC and SQL-99 style
LEFT OUTER JOIN
.
-
The following are new reserved words:
LEFT
, NATURAL
,
USING
.
-
The client library now uses the value of the environment variable
MYSQL_HOST
as the default host if it's defined.
-
SELECT col_name, SUM(expr)
now returns NULL
for col_name
when there are matching rows.
-
Fixed problem with comparing binary strings and
BLOB
values with ASCII
characters over 127.
-
Fixed lock problem: when freeing a read lock on a table with multiple
read locks, a thread waiting for a write lock would have been given the lock.
This shouldn't affect data integrity, but could possibly make
mysqld
restart if one thread was reading data that another thread modified.
-
LIMIT offset,count
didn't work in INSERT ... SELECT
.
-
Optimized key block caching. This will be quicker than the old algorithm when
using bigger key caches.
