Hi.
I've got a table with some fields, which I created with VARCHAR(100).
I want to optimize this table, and I want to modify the length of these
fields from VARCHAR(100) to VARCHAR(maximum_length), where "maximum_length"
is the length of the record with the longest field.
I could create a Perl
Thank you all for your suggestions.
So it's very important to make primary fields be as smaller as possible,
right? I'm going to change 'isbn' from VARCHAR(100) to VARCHAR(25) and, if
possible (I might change my code), from VARCHAR to BIGINT.
By the way, which are optimal values for "key_len" par
type=const
possible_keys=PRIMARY
key=PRIMARY
key_len=302
ref=const
rows=1
Extra=

Hi.
My hosting provider recommended me to optimize my 200,000 record table in
order to save resources.
I do _always_ this query:
SELECT * FROM books WHERE isbn='foo' LIMIT 1
The primary key of this table was 'id', and 'isbn' was and INDEX field.
I've modified this:
ALTER TABLE books DROP PRIMAR
