Re: Newbie: How do I copy over a new database?
A file with extension .sql is an SQL set of statements. Perhaps it is the CREATE TABLE query to create the table in MySQL. You can open the .sql file with any trxt editor and examine the query it contains.

Newbie: How do I copy over a new database?
Please forgive this easy question from a newbie: I was given a MySQL database file from a client with a .sql extension. I already have several databases setup and running under MySQL on our server. But how would I copy this new database over? Do I need to load it or can I copy it as is into a directory. Please advise. Thanks in advance!

Re: Remote admin of MySQL from Win 2K
Unless I am missing something (and that is very likely), MySQL is installed on the "closed" Yahoo RaQ-4 Cobalt server. Now on my Linux server*, I had to go in as root and enter a user and give what servers are allowed to access it. With the yahoo server, the *only* access is via a Web page. When I tried to access MySQL mysqladmin, it said the the URL that was attempting the access was not allowed. Of course, the URL was that of my ISP. I have told my client that either they need a server with full access rights *or* put the DB on my Linux server (not really on the top of my list - not my business). Todd * This is the first time I have ever used MySQL and I am trying to see if I can around not being able to access Interbase (my usual DBMS). -- Todd Cary Ariste Software 2200 D Street Extension Petaluma, CA 94952 707-773-4523 [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

I am getting real interested too. :) I took a look at the manual, but I did not see answers to a simple question like whether innodb files are compatible (query-wise) with MyISAM tables, for instance, or whether I need to rewrite all queries. Perhaps a guru here could explain this. My MySQL powered news server I am building may not contain the world's most vital data; but in case of a crash, all clients connected would have their message-ID tables screwed up permanently. And it seems like innodb can handle crash-recovery a lot better than MyISAM tables. Would anyone be willing to shed some light on this?

Check tables?
Hello, Is there a way I can do a "CHECK TABLES" which will return an exit code of some sort, to use in a shell-script? Looking at the output of a myisamchk is fun, but I rather have a utility too that will report an error-status that I can use to decide whether to make a backup/restore, etc. Thanks - Mark P.S.

RE: Alter table and add cell at a time.
You have a different row for each answer because each answer has its own
INSERT. A solution would be to do a single INSERT (with quiz question
or some other data) and then for each answer do an:
UPDATE $table SET $value2='$value' WHERE id='$question_id'
You'd just have to keep track of the row ID (which would be the primary
key in this example).
Nice to see quiz software being built by an .EDU!

Quick little followup question:
if i have this:
for ($n = 1; $n <= $quiz[number_answers]; $n++) {
$table = $qcode."_answers";
$value = $answers["answer".$n];
$value2 = "answer".$n;
$query_alter_table = "ALTER TABLE $table ADD $value2 TEXT NOT
NULL";
$query_add_answers = "INSERT INTO $table ($value2)
VALUES('$value')";
if (mysql_db_query($database_glob, $query_alter_table,

echo "Answer $n: $value has successfully been
added to the Quiz\n";
} else {
echo mysql_error() ." 1";
}
} else {
echo mysql_error()." 2";
}
}
How do I get the $value to be in the same row as the preceding one? now
it comes like this:
++-+-+-+-+

++-+-+-+-+
| 1 | answer1 | | | |
| 2 | | answer2 | | |
| 3 | | | answer3 | |

so it's like this?

Before he inserts a new record, you do a lookup using his member_id and see if he is about to exceed his limit. If he does, display a warning message that allows him to buy more record space. You make more money off of him and if he doesn't like it, he is limited to the # of records he has and he will manage his records better. It is all automatic.

Joining same table twice for different rows -- possible?
Hi, Consider the following schema: Database.Users: id username Database.Log: id userid1 userid2 entry If I'm SELECT'ing on the Log table and I want to pull usernames out of Users table for both users (which will most likely be unique) is there a specific JOIN for this? Forgive me if I've missed something in the manual pages; I've always had to do two SELECTs and thus have been looking for a quick[er] solution to this for some time now. Thank you in advance! Ron Jamison (moderators: although I've looked at the manual page plenty of times before, http://www.mysql.com/doc/manual.php?search_query=join today produced the following: "Search results Did you mean jan?

Add existing related data to a table
Hi, I'm looking for some suggestions of making a one time update to some of my tables to make them useable with new forms and queries I'm creating. I have a series of tables which hold related data and only the last part of the data is stored in a final table, which means to search data based on some of the information higher up the table structure is making some very complex and dodgy queries. I want to insert the related data into the final table but can't think of a way of doing it. The example below might help me explain better what I mean. Consider two tables - TableA which contains PicID and KeywordID TableB which contains SubcatID and KeywordID What I want to do is insert the corresponding values for relating to KeywordID for SubCatID into a new column in TableA. Any suggestions how to work this to add the extra information to existing records?

RE: MySQL/InnoDB question
I don't know the answer to this in mysql, but in oracle, while you can have big files, I've seen tables divided at, say, the 1 million record mark. So there could be 5 files for a fast 5 million record "table". This is seamless to the user if there are views. Alas, mysql doesn't have views :-(. -Original Message- From: Craig Vincent [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 16, 2002 6:28 PM To: MySQL Subject: MySQL/InnoDB question I'm not new to MySQL but have only recently familiarized myself with InnoDB. One question I have so far been able to find an answer on is the datafiles. Let's assume I have 5 GB worth of information, this information changes regularly.

How can I delete from a table the results of a join query.. I.e, join two tables together, get the resutls, now want to delete that data from one of the tables... Do I have to create a tempory table, hold the data, and delete from the one table data matching in the temp table, or can I just combine a delete statement with my original query...? here is my query, which works.. select distinct table1.ticker_name from table1 LEFT JOIN on table2 on (table1.ticker_name = table2.ticker_name) where table2.ticker_name IS NULL; Thanks, Taylor Taylor Lewick Unix System Administrator Fortis Benefits 816 881 6073 "Help Wanted.

RE: Remote admin of MySQL from Win 2K
Uhh, Hmm you probably are the owner, aren't you? (Wasn't reading that as a server, was reading just a name) Contact your supplier or sun directly (whomever installed the software) and ask them for the root password for your mysql server ( default installation however does not require a password, it doesnt have a password ) Later you can use the mysql client GRANT function to create users for mysql ( or whatever your interface calls the user permission process) -Original Message- From: Luc Foisy [mailto:[EMAIL PROTECTED]] Sent: Friday, May 17, 2002 4:23 PM To: 'Todd Cary'; MYSQL-List (E-mail) Subject: RE: Remote admin of MySQL from Win 2K Do you want to access the whole MySQL server?

Sharing an instance of a connection will work, but you will have performance problems, and it is impossible to demarcate transactions when you do this.

Re: Remote admin of MySQL from Win 2K
Have you tried using phpMyAdmin?? It allows you to connect to several different host quiteeasily. You can download it at: http://www.phpwizard.net/projects/phpMyAdmin/index.html And actually any of the GUI front end apps for M$ should be able to connect to a remote server (I think).

OSDL Introduces OSDL-DBT-1
Hello everyone, I thought some folks may be interested to know that the Open Source Development Lab (OSDL) has released a database test kit that is a derivative of the TPC-W (http://www.tpc.org/tpcw). The kit is currently adapted for SAP DB, but we hope that people are interested in contributing to the project to make it work with MySQL.

You probably don't want to be doing your archiving and reporting on the same database. Set up replication, and do your queries on the slave while the master gets the updates. Moving to InnoDB tables might help with table contention, since it's got row-level locking. If there are only updates and few changes, then even moving to MyISAM will get you a big win, since appending a row doesn't lock the table. > We have tested Oracle and PostgreSQL which fell behind on the ingest. > The current production system uses regular ISAM files, but we need to > make a certification which requires a relational database.

RE: Real-time data warehousing
We have used the predecessor to the OTL for many of our apps and were planning to use the OTL for the new system. I thought the OTL used ODBC to make its connection with databases other than Oracle. I know the OTL supports Oracle natively. Sadly we cannot move to Linux. We managed to get our web servers on Linux, but the big iron will always be Sun here (Company policy). There has been talk of getting Oracle 9i? because Oracle has told us it is much faster, but we are not holding our breath.

RE: Real-time data warehousing
I forgot to mention, we have Oracle in-house, and the machine the MySQL database will reside on is a 2 proc Sun box with 1.5G of RAM. The Oracle databases reside on a 16 proc Sun box with 10G of RAM. The decision to go or not go with MySQL is not based on money, it needs to be based on performance. We currently use Oracle in-house for everything, but its speed hasn't been its selling point, and for this application we need lots of speed. That is why we are leaning toward MySQL, but were not sure if it could keep up with the addition of the user community. I had one other question, how much of a performance hit would we take with MySQL if we connected through MyODBC? Thanks again, Brad -Original Message- From: walt [mailto:[EMAIL PROTECTED]] Sent: Friday, May 17, 2002 11:47 AM To: Brad Teale Cc: '[EMAIL PROTECTED]' Subject: Re: Real-time data warehousing Brad, We're in process of evaluating mysql vs our current Oracle 8 system. Importing data is much faster in mysql than oracle according the numbers we're getting. However, from our benchmarking, Oracle seems to be faster on the queries (no writes to db during query time). The table were running our queries against has 46 coulmns and 14 indexes (some columns indexed twice in multi-column indexes). All queries are based on indexed columns. We've also run into some issues trying to delete indexes, 14+ hours before we killed the db and reloaded data, but I may be something stupid. One note on Oracle, $30,000+ for a single processor licence. From our testing, it looks like the bottleneck is disk I/O not processing power. With Oracle, you have better control over which disks your data resides on which lets you balance disk I/O better. However, for $30k, you can buy 10 15,000 rpm drives, stripe them, and then buy another server for replication of data and still have $25K left over. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

Try: http://lists.mysql.com/php/unsubscribe.php Brad, We're in process of evaluating mysql vs our current Oracle 8 system. Importing data is much faster in mysql than oracle according the numbers we're getting. However, from our benchmarking, Oracle seems to be faster on the queries (no writes to db during query time). The table were running our queries against has 46 coulmns and 14 indexes (some columns indexed twice in multi-column indexes). All queries are based on indexed columns. We've also run into some issues trying to delete indexes, 14+ hours before we killed the db and reloaded data, but I may be something stupid. One note on Oracle, $30,000+ for a single processor licence. From our testing, it looks like the bottleneck is disk I/O not processing power. With Oracle, you have better control over which disks your data resides on which lets you balance disk I/O better. However, for $30k, you can buy 10 15,000 rpm drives, stripe them, and then buy another server for replication of data and still have $25K left over. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

Replication
Can you replicate tables in MySQL version 3.23.44. As part of a University project I wish to distribute certain tables across the network and obviously keep the data synchronised with the original table. Unfortunately I am limited with only one server, so to demonstrate this is it posible to create a replicate table sitting on the same server that is regularly synchronised with changes. any idea how you can do this. Any help would be much appreciated.

RE: Query question "average per hour per agent"
[snip] I have a database of tickets and I want to get "the average numbers of tickets created per agent per hour over a date range" in the format: Hour | Avg per agent This is what I have so far: SELECT HOUR(created) AS hourcreated, COUNT(*) AS sum-per-hour FROM remedy WHERE (created>='2002-4-25' AND created<='2002-04-30') GROUP BY HOUR(created) This query only gives the SUM of tickets per hour. Is there a way to get the number of distinct "submitters" per hour so I can divide that by count to get avg/hour? [/snip] You probably need a crosstab query and I would need to see some of the table to help you create it. It would look something like; SELECT DATE(created) AS DateCreated, SUM(IF(HOUR(created) = '10:00', 1, 0)) as "10 am", SUM(IF(HOUR(created) = '11:00', 1, 0)) as "11 am", SUM(IF(HOUR(created) = '12:00', 1, 0)) as "12 am", SUM(IF(HOUR(created) = '13:00', 1, 0)) as "1 pm" FROM remedy WHERE (created>='2002-4-25' AND created<='2002-04-30') GROUP BY DATE(created) would give something like; +-+---+--+-+---+ | DateCreated | 10 am |11 am | 12 am | 1 pm | +-+---+--+-+---+ | 2002-04-25 | 159 | 72 | 0 | 0 | | 2002-04-26 |28 |0 | 14 |14 | | 2002-04-27 |22 | 17 | 17 |17 | | 2002-04-28 |36 | 13 | 49 |85 | | 2002-04-29 |12 |0 | 12 |12 | | 2002-04-29 |12 | 83 | 72 |12 | +-+---+--+-+---+ HTH!

Multiple Slaves to single Master Replication
Having read the mysql release notes on replication, I am unsure whether mysql will support the following scenario. Can anyone tell me. 1. Multiple master databases into a single slave. If this can be done, I understand that the applications must control the update to avoid conflicts. 2. Data being updated on the slave being replicated to a selected master, again with the application controlling how the updates are managed. --- Paul Daniels Technical Director Evolution Systems Ltd Tel: 01270 588228 Fax: 01270580129 - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

set connection as instance variable ( servlet and mysql)
Hi, My application is about online exam with java servlet as tool, tomcat 3.2.3 as server solution , mysql 3.49 as the backend. considering 180 students take the exam at same time within 50 minutes, there are a lot of transactions with database. what i did right now is to define connection in local variable(within doGet or doPost method), every time this servlet is called, new connection is created. after transaction is done, this connection is closed. I am worrying the speed.(it will comsume a lot connection and time for open new connection). so I am thinking to define connection as instance variable in every servlet, so it can save sometime to open new connection. However, I am not sure if it will cause multi-thread problem? How and when i can close the connection. __ Find, Connect, Date! http://personals.yahoo.ca - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

Query question "average per hour per agent"
I'm having a problem in a query that I'm trying to do. I have a database of tickets and I want to get "the average numbers of tickets created per agent per hour over a date range" in the format: Hour | Avg per agent This is what I have so far: SELECT HOUR(created) AS hourcreated, COUNT(*) AS sum-per-hour FROM remedy WHERE (created>='2002-4-25' AND created<='2002-04-30') GROUP BY HOUR(created) This query only gives the SUM of tickets per hour. Is there a way to get the number of distinct "submitters" per hour so I can divide that by count to get avg/hour? perhaps I'm not thinking straight and I'm missing something -- any ideas??

Real-time data warehousing
We are warehousing real-time data. The data is received at up to T1 speeds, and is broken up and stored into the database in approximately 25 different tables. Currently MySQL is doing terrific, we are using MyISAM tables and are storing 24 hours worth of data but we don't have any users and we need to store 72 hours worth of data. Our concern is that when we start letting our users (up to 200 simultaneous) hit the database, we won't be able to keep up with ingesting and serving data with the MyISAM locking scheme. We have tested Oracle and PostgreSQL which fell behind on the ingest. The current production system uses regular ISAM files, but we need to make a certification which requires a relational database. Also, the current production system doesn't have the feature list the new system has. Is there a better database solution or do you think MySQL can handle it? If MySQL can handle it, would we be better off using InnoDB or MyISAM tables?
