How can I extract a middle segment of text in mySQL. For example a column contains

Hi,
I just wondering if anyone notice or can confirm this: I tried to load
11 million records using mysqlimport using both 4.1.3b and 4.0.20.
4.1.3b took 1.5 hours, but the 4.0.20 took over 10 hours. This
includes loading the data and then build the index.
Thanks

Miss Brasseur,
Sorry for the Mr... You are right. Id did not know.
The reason why I think it was SSL related is
because that error only comes up when I try to
compile with SSL support.
Also, on the includes where the compiler fails,
you can see:
-I.. /data/OpenSSL/include/openssl
Which
Mr. Fisher,
Yes, that seems to be the problem... It is adding a
space before the path.
Also, the path should be static; however, it is using
../data which is wrong since I am compiling under
/data/Software/mysql and the OpenSSL directory is
directly under /data.
I did a grep for /data/OpenSSL
Assuming there are no parts of a name that include more than one word
(e.g., Mary Jo being someone's first name), an easy way would be to
use SUBSTRING_INDEX.
First Name = SUBSTRING_INDEX( namefield, ' ', 1 );
Middle Name = SUBSTRING_INDEX( SUBSTRING_INDEX( namefield, ' ', 2 ), ' ', -1 );
Last
I guess that would depend on what you consider a last name or a middle
name
A typical western name has 3 parts, like your example. However there are
many names like van der Plaats or de la Hoya that are not so easy to
detect based simply on what space to split the name at.
What about people

I would try not to query MySQL on each iteration of the loop. While a
dozen or so queries may not make a noticeable difference, hundreds or
thousands may. It's not a scalable technique, whether you need to scale

The end result will be the same, it's just a matter of the structure

be retrieved bit by bit and broken up into multiple lists or joined and

Currently we have one way master to slave replication setup.
The master has 2 innodb data files, the second has now grown

How is this possible? They are both storing the exact same
data. Is there some way to trim the 50gb+ file down ?
I agree with Peter. Hit the database only when necessary. You can even
eliminate some JOINS entirely if you cache the contents of **certain**
tables in application-side arrays However(!!) _*you*_ are now responsible
for searching those arrays efficiently. Here's an example:
