RE: Mysql Table Case
Answer is No. Case-sensitivity of table names depends on operating system you are running mysql on.MySQL stores table definitions in TABLENAME.* files. So it will always be case-sensitive on *nix and case-insensitive on windows.

RE: Replication slave repeatedly gets error 1159 from master
Check the list. This question has been asked before many time. You can set net_read_timeout variable to bigger value to avoid this problem. Still no one knows (or answered) impact of net_read_timeout and wait_timeout. which one takes precedence.

For instance, if I've got a table create table updater( id int not null primary key auto_increment, is_active int not null default 1 }; insert into updater(is_active) values (1); insert into updater(is_active) values (1); update updater set is_active = 1; Would MySQL essentially disregard this update statement b/c the values contained within the table are already 1? Now, I realize that the values wouldn't be altered, but does the dB do pre-checking and see which (if any) rows would be affected by the query, and only run the update against rows that would be changed?
