Dear users
can someone clarify the difference between manipulate and analysis !!
Manipulate should genreally mean changing the data and analying would mean
investigating.
So when we talk about Buffereing and Overlaying, does it come as part of
analysis or manipulate.
Or if someone can explain
Hi All,
I performed the backup (mysqldump -u username -p db backup.sql) of a
database on a Win32 (4.0.15-max-debug) server in order to restore it on
Linux server (4.0.15-9)
When I try to restore it on the linux machine (with mysql -u username -p
db backup.sql), there is an error saying:
Unfortunately there is no standard way, i use a
directory called includes
and within that include_top.php includes global
stuff across pages and a

Hi
Is there such a statement where, if the insert fails (due to a duplicate
record) an update will happen

No, but you might want to look at REPLACE INTO to simulate this
effect.

Take a look at REPLACE and INSERT .. ON DUPLICATE KEY UPDATE statements:
http://dev.mysql.com/doc/mysql/en/REPLACE.html
The last suggestion is useful when you do care which entries you get,
as you can use one order for limit and another for presentation.
For example, if you'd like the LAST 10 rows, but sorted in FORWARD
order, you can use something like
(select * from HISTORY order by version desc limit 10)
Use REPLACE instead. It is similar to the INSERT except that, it will
replace any old record that match - with the new one. A replace
statement may look like this:
REPLACE INTO TestTable (TestId, User) VALUES (007,Bond);

I think you want a UNION, not a JOIN.
Availabilty of UNION depends on the version you are running.

Paul book is killer, I have the 1st and second addition - but to answer your

something in mySQL itself to do that it can't. To create tables you can do
something like this.

Use indexes. Make sure your indexes are on the right side of the where
clause ie.
SELECT col1,col2 from tablewithproperindexes where col3=const_index_lookup.
Or you can use a dirty read as your transaction model to help out a TINY
bit.
