-
Fixed comparison of
DATE
and TIME
values with NULL
.
-
Changed language name from germany to german to be consistent with
the other language names.

Fixed sorting problem on functions returning a
FLOAT
. Previously, the
values were converted to INT
values before sorting.

Fixed slow sorting when sorting on key field when using
key_column=constant
.
-
Sorting on calculated
DOUBLE
values sorted on integer results instead.
-
mysql
no longer requires a database argument.

Changed the place where
HAVING

incorrectly had it last.
-
Added Sybase command
USE database
to start using another database.
-
Added automatic adjusting of number of connections and table cache size
if the maximum number of files that can be opened is less than needed.
This should fix that
mysqld
doesn't crash even if you haven't done a
ulimit -n 256
before starting mysqld
.
-
Added lots of limit checks to make it safer when running with too little
memory or when doing weird queries.
