Indexing in MySQL.
If while indexing a table I retrieve data from same table the indexing

repairing keycache for days when the indexing shouldn't take more than

Can someone please explain!

to whom it may concern,
I need some help regarding transactions using innodb tables.
I am running MySQL 3.23.51-Max as database server and developing a web
front-end using ASP. Many of the tables used are of innodb format since it
is imperative for me to use transactions in most of my scripts.
Hi Alec-
Your sub-select query can be written as:
select t1id from t1 left join t2 on t1id = t2id where t2id is null
in MySQL.
The example is actually given in the MySQL manual itself (section 1.7.4.1).

Paul,
You have to use the results of one select to generate lots of update

Alternatively, if it's a one off, generate a script file
