The following known errors or bugs are not fixed in MySQL 3.23 because fixing them would involve changing a lot of code that could introduce other even worse bugs. The bugs are also classified as "not fatal" or "bearable."
You can get a deadlock if you use LOCK TABLE to lock multiple tables
and then in the same connection use DROP TABLE to drop one of
them while another thread is trying to lock it. (To break the deadlock, you
can use KILL to terminate any of the threads involved.) This issue is
resolved in MySQL 4.0.12.
SELECT MAX(key_column) FROM t1,t2,t3... where one of the tables are
empty doesn't return NULL but instead returns the maximum value for the
column. This issue is resolved in MySQL 4.0.11.
DELETE FROM heap_table without a WHERE clause doesn't work on
a locked HEAP table.
