In the first process, I'm summarizing a large amount of time series data

my query is SELECT * from $TableName LIMIT $name
now $name goes from 1 to 4, the 4 rows in my database, but i just want the

How do i do this?

Description:
Very similar to a problem I reported more than 2 years ago, which

Mark,
if you do not explicitly do
SET AUTOCOMMIT=0
then MySQL automatically calls COMMIT after every SQL statement.
If you set AUTOCOMMIT=0, then you should yourself call COMMIT after each

and that you get a fresh
