hey guys Is there anyway to speed up group bys for a left join when what your grouping by is on the left part
use ‘ not`
learn the syntax rules
ahhhhhhhh … thanks archivist …
you are an O:-)
can I somewhow use the call result (a select) from a stored procedure in another procedure?
with a cursor or loop or so?
hey, i wanna upgrade from mysql 3.23.x to mysql 5
apart from backing up all the databases. is there anything else i should do before the upgrade
apart from pray
the datetime format has changed beware of that
timestamps are different
bizzeh, see upgrading docs for issues
joins change a bit
time functions are fine, but if you convert outside php mysql web hosting unixtimestamps back and forth there will be trouble
and passwords are different
they all get purged
i always select UNIX_TIMESTAMP(field) anyway
mysqldump
http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html
omg why?
because mysql3 timestamps are not unix timestamps
and php cant strtotime mysql3’s times
what is preferred? second or third? select now(), now() – interval 1 day, date_sub(now(), interval 1 day);
maybe i should ask, which one is (more) portable?
Hi all!
Hi one!
ping
who me
Yes you!
i reckon you’d know the answer to my simple question
How can you create databases with specific default character sets from within a script?
dunno
oh
mysqladmin -u root -p create foobar_blah default character set utf-8 collate utf8_general_ci doesnt work
use a real sql host statement instead of mysqladmin?
mysql -u root create_foobar_blah.sql
ah okay, cool thanks
hello
how can i search for all records in a week ?
date_sub(now(), INTERVAL 7 DAY)
someting like that
bye all!
ok, thanks
well sorry for being a pain in the ass,
but it got mysql to work in chroot
i just needed to chown a bunch of folders
and add some libs here and there
hey guys. Is there anyway to speed up group bys for a left join when what your grouping by is on the left part of the join?
Voltaire, use explain check index usage
hmm. good point.
ta
is it possible to alter table add column XXX ONLY if column doesnt exist?
is there a verbose way to use mysqldump, to see for example how much it’s dumping so far ?
hey guys do i need to create a hard link between mysql and mysqld
if i chrooted mysql
bye bye
why would you create a hard link between mysql and mysqld?
SELECT * FROM table ORDER BY MAX(field) LIMIT 1
Danielss89, no SELECT * FROM table ORDER BY field desc LIMIT 1
Danielss89, you need an index on the field for maximum speed
yes archivist
anyone any Ideas why this SQL wont run
http://rafb.net/p/8FNieU49.html
mysql says #1064 – You have an error in your sql syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘——————————————
`1_desc` text NOT NULL,
`1_head’ at line 24
Take a look just before the quoted text
that —————— looks suspicious
heh
And learn about database normalization please!
eh
You have combined 20 different tables into a single one
what do you mean database host normalization, we need details
what do i need to import a access db
I dont need 20 different tables
religion
normalization
http://dev.mysql.com/tech-resources/articles/intro-to-normalization.html and http://datamodel.org/NormalizationRules.html and http://mysqldump.azundris.com/archives/20-Nermalisation.html and some here http://www.keithjbrown.co.uk/vworks/mysql/
I would suggest one of the more outlandish cults, perhaps one with live human sacrafice
religion ?
Religion is not defined in RDBMS theory nor in SQL standard
sorry, I realld dont like access, I was being sarcastic
what do you guys have about like and no like. As iam porting access to mysql its clear iam not liking it too..but its a job.
Relational databases are optimized for tables with few columns and millions of rows. Just adding one more column will make it possible to cut your table to 40 columns, but even that is too much for such structure
It’s like saying your religion says you must only drive your car backwards. Possible, but not very efficient
xored, you guys!!! sorry man. I know jack anyhow
Importing tables is doable, but I hope you don’t expect MySQL to import anything else like forms and reports
why should it import forms ?
they are based on the data..they stay in the access-app
For single table the fastest way would be to export to tab delimited (or any other delimiter) text file and then LOAD DATA in MySQL
Or you can connect directly from Access to MySQL with Connector/ODBC
Or you can use Migration Toolkit
ok odbc driver. do i have to install it on debian etch for mysql hosting ?
I wish the Migration Toolkit did not rely on java
http://www.mysql.com/products/tools/migration-toolkit/
No. You install it on windows box where the Access resides
ah !
so its nothing server sided, its client sided
Where do i get the ODBC driver ?
Indeed
is the migration-toolkit free ?
dev.mysql.com/downloads
Free as a bird
thank you :9
hello salle
Hello here
but then you need the java jre download fails for the last few days for me
get a new isp!
