RE: varchar to char ...
What do you mean by optimization of the column? Are you saying that char takes less space than varchar or the performance on char is better in queries compared with varchar ? The whole concept of CREATE AS is that you want target table to inherit all the properties with the data of the source tables and the columns. So I don't understand why should/would it change the data types of columns. thanks Vivek -Original Message- From: bvyas3 [mailto:[EMAIL PROTECTED]] Sent: Friday, June 14, 2002 6:36 PM To: CHAUDHARY, Vivek; mysql Cc: bvyas3 Subject: Re: varchar to char ...

RE: Duplicate Keys
There are couple of ways you can do it. 1) You can use the following sql to find out duplicate rows and then write few more sql to delete duplicate. SELECT column(s), count(*) FROM table-a GROUP BY column(s) HAVING count(*) 1; then massage the data with couple of more sqls. 2) This way you can dump unique rows in another table and then drop this table, recreate it and copy the unique rows. CREATE TABLE table-B (structure same as table-A); INSERT INTO table-B SELECT DISTINCT * FROM table-A; ( Assumption is that rows are duplicated) DROP TABLE table-A; RENAME TABLE table-B TO table-A; 3) You can try; ALTER IGNORE TABLE table-A add unique (columns_with_unique_values); Be careful in using this as there are some issues with this. cheers Vivek -Original Message- From: oswaldo [mailto:[EMAIL PROTECTED]] Sent: Friday, April 26, 2002 11:20 AM To: mysql Cc: oswaldo Subject: Duplicate Keys Hi List Sorry for the newbie question.

This is a major issue for us as well. We have some tables that need
periodic cleaning of old data and it can take hours upon hours to do
that. What our workaround is, and it is IMHO, sub-optimal, is to use
the LIMIT feature of DELETE in MySQL, and issue the delete in a loop
until no more items are deleted. Something like this, in Perl:
my $sth = $dbh-prepare("DELETE LOW_PRIORITY FROM playlog $clause LIMIT ?");
$sleeptime = 0;
do {
print "Sleeping... $sleeptime seconds\n";
sleep($sleeptime);
my $stime = time;
print scalar localtime $stime," (start delete)\n";
$sth-execute($limit);
$affectedRows = $sth-rows();
my $etime = time;
print scalar localtime $etime,": ";
my $diff = $etime-$stime;
print "Deleted $affectedRows rows... $diff seconds\n";
$sth-finish();
# sleep half the time it took to delete, if longer than 30 seconds.
$sleeptime = $diff 30 ? int($diff/2) : 1;
} until ($affectedRows $limit);
Assuming $clause = 'WHERE .' is your match for rows to delete,
this will delete things in batch size of $limit (I use 200 rows), and
sleep between the deletes to let other threads do their thing with not
too much delay.
Ideally, MySQL would allow the delete to be concurrent with other
operations.

Re: mySQL vs Oracle
"AR" == Ann Ricchiazzi [EMAIL PROTECTED] writes: AR I am trying to choose between mySQL and Oracle for a Linux server. My AR specific questions are: AR 1) Will mySQL handle 3000 hits/day well? You need to define what a "hit" is. Is it a simple select on the primary key of a single table or a multi-table join without indexes? How are your "hits" distributed over the duration of the day? Also, how big are you expecting your data tables to be? I'd venture to say that yes, MySQL can handle 3000 queries per day, but it is hard to say without knowing what your load expectations are. AR 2) Does mySQL handle multi-media file formats? For example, if I want to AR store audio clips, or Flash movie clips, or PowerPoint presentations, AR can I do so? MySQL can store binary objects. You probably don't want to do that for these things but instead store a pointer to a URL or filesystem location. The file system access would be much faster than cramming the data down the database socket connection. AR We make the decision this decision at 3:00 today. Your advice will be AR most helpful.
