mysqlgui about
Dear Sirs and Madams, I have installed mysqlgui-static on my PC. Please let me know how to start it, so that I can use it. 2. Have you or anyone else developed any utility to make it easy to populate the tables? The default method is too cumbersome. If so, kindly direct me to the links etc. 3. One book on Mysql talks of a /contrib page on your website where third party utilities for mysql are listed. when I try to search it it get the message page not found. Has it been removed or moved? Pl. let me know. From whatever little I have seen of it, Mysql is superb!! Pl. keep up the good work. Best luck to all of you in all your noble endeavours. R C Kathale, Bhavnagar, India.

Would MySQL consider to publish something like the following as found at Netbeans; http://www.netbeans.org/articles/roadmap.html and even though their roadmap is not specific, some indication of timing is derive-able? Hey, that's pretty cool. There's a more low-tech version for MySQL here, I guess: http://www.mysql.com/doc/T/O/TODO.html It's the same idea.

Fw: Porting from MS SQL to MySQL
- Original Message - From: Richard Burgmann [EMAIL PROTECTED] To: Markus Lervik [EMAIL PROTECTED] Sent: Sunday, January 20, 2002 9:53 PM Subject: Re: Porting from MS SQL to MySQL Hi Markus, I'm an IT Consultant by trade and have been involved in lots of green fields projects and conversion projects over the years. Without knowing the details of your situation I will risk giving an opinion. 1. If the company has a developed/deployed product DESIGNED to run on MS SQL you can pretty much guarantee they are using every proprietary 'feature' of it and the actual industry standard SQL code is in the minority. 2. Given (1), It will be a major effort to undertake a conversion. This is the whole point of adding extra 'features' to data base servers, and every vendor does it. 3. Given (12), I think 18K euros wouldn't even cover the scoping and design phases. So why quote a low ball figure? In my experience I have found this is often done to get the work in the first place. Once you have committed to their product, you will find that the price of conversion just keeps going up until you eventually capitulate and accept their product as is. Alternatively they naively believe they can do the work and go broke trying to do the conversion on a fixed price contract (I have actually seen one software development company go broke this way). - Kind Regards Richard Burgmann Consultant E-Mail: [EMAIL PROTECTED] - Original Message - From: Markus Lervik [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, January 19, 2002 12:16 AM Subject: Porting from MS SQL to MySQL Hello all!

RE: Understanding throughput with JDBC
Hello Mark, Thank you for the note and feedback. BTW, it was not over a network. Both on local PC. So all the time went into building the resultset in memory. I'm surprised at the time that takes.

I want to understand where the time is going to and whether there is something I can do about it, with the following query when using JDBC; Here is the table declaration; CREATE TABLE Memberships (EMAIL CHAR(60) NOT NULL, NAME CHAR(50) NOT NULL, MIDDLEINITIAL CHAR(1) NULL, SURNAME CHAR(50) NOT NULL, NEWSLETTER CHAR(1) NOT NULL, USERNAME CHAR(15) NOT NULL, PASSWORD CHAR(15) NOT NULL, COUNTRY CHAR(50) NOT NULL, PRIMARY KEY (EMAIL)) TYPE=InnoDB MySQL table memberships has 110080 rows. Here is the select statement I use with JDBC; SELECT * FROM memberships ORDER BY EMAIL Same select statement I use from the MySQL 'commandline'; mysql select * into outfile 'mysql20.txt' from memberships order by email limit 20; My observations; A. When running the SQL from the MySQL 'commandline' with above statement this is the response; mysql select * into outfile 'mysql20.txt' from memberships order by email l imit 20; Query OK, 110080 rows affected (1.27 sec) B. When running the exact same select as stated above in a java program using JDBC, from when issuing, ResultSet rs = stmt.executeQuery(query) until the java program gets control back, to create the resultset, takes 23-25 seconds; I ran program several times. Please advise whether this is to be expected, or whether I could alter anything to get comparable results via JDBC as with MySQL 'commandline'? No network traffic in the first case, always network traffic in the second. No memory allocation in the first case, needing to allocate space for the entire result set in the second (the MySQL protocol doesn't mesh really well with the JDBC spec's requirements at this point in time, so the JDBC driver is required to read the entire result set in to memory to allow things like thread safety and multiple concurrent queries without being overly complex). With JDBC, it is usually not a good idea (with any driver) to select a whole slew of rows, because you won't get the performance you desire. In most cases it isn't necessary, and isn't the most efficient way of doing things either. When developing client server applications, you should use the database for what it's good for, manipulating, aggregating and transforming large amounts of data, and then look at the results (which will hopefully be smaller). Only in very special cases do you need to return large result sets (like OLAP for example). I guess it comes down to, what exactly are you trying to do selecing 110,000 rows, and do you need to return the whole result set at once...If you're just trying to dump it to a file, why are you doing that with Java when MySQL can do it directly? -Mark - 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?

Echoing Values Inside Single Quotes for an Insert (PHP)
Hi,
I have a while loop pulling information into an editing form. It labels
variables dynamically as so:
name=schooling?php echo $counter?
Where $counter is augmented each time through the loop. In order to then
insert these, I need to do an insert of $schooling$counter. Below is the
statement I've been trying to use, but doesn't work, it instead inserts
the value of $i (another counter in a while starting at zero where $i
$counter) How can I make it insert $schooling$i instead?
$result = mysql_query(INSERT INTO skills (member_id, name, schooling,
certifications, description) VALUES ('$member_id','$skill_name +
$i','$schooling+ $i','$certifications + $i','$skill_description$i'));
Thanks a bunch.

RE: Understanding throughput with JDBC
Hello Monty, Thank you for your note and feedback. After getting excellent assistance, I'm using JDBC setMaxRows rather than LIMIT, which gives me portability. I'll investigate SQL_CALC_FOUND_ROW option further. I notice I would need to first upgrade to MySQL 4.x, though and then find / work out how to use it with JDBC.

Re: Fulltext build 2 days and counting...
My experience (atleast with the 3.23 series) is that full text indexing is not worth the hassle if you have an existing HUGE database... I let mysql run for about a day or two on a 20gb database (dont remember exactly how many rows it had) before giving up (note this was using 3.23.39). I found on such a large dataset the full text indexing didnt do very well (queries took 15-20 seconds on a pIII 700mghz 512megs of ram dedicated to mysql). Anyhow... good luck, hope things turn out better for you than they did for me. ryan - Original Message - From: Steve Rapaport [EMAIL PROTECTED] To: MySQL List [EMAIL PROTECTED] Sent: Sunday, January 20, 2002 5:25 PM Subject: Fulltext build 2 days and counting... Okay, does anyone know how long this will take? 22 million records, fulltext index on a single field, first 40 chars. record length 768 chars, variable. It's been running for 2 days, processlist quotes time at around 10. Index file still growing occasionally, up to 3Gb. Should I let it continue or give up? Will this take another 2 days? another week? Anyone else with experience to get a rule of thumb? I'm using mysql 3.23.37 on a dual processor intel Redhat, 700Mhz, 1G ram. -- Steve Rapaport still at large - 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?

Re: Porting from MS SQL to MySQL
On Friday 18 January 2002 17:30, you wrote: We've requested a database from different companies, and specifically said we wanted MySQL or PostgreSQL because of the open source angle and we're a library. One company offered MS SQL as the platform and said that they can later on port it to MySQL. For this they wanted 18 000 euro. Now, what I want to know is, how easy is it to port a (fairly complicated) database from MS SQL to MySQL? It can't be work worth 18 000 euro, now can it? 2) If you want MySQL or PostgreSQL, why exactly would you want to install MSSQL, and then upgrade later? Both PostgreSQL and MySQL will run on Windows (although again, I'm not sure why you would want to do that if you have a choice). That's the point. I have no idea whatsoever as to why this company wants to FIRST do the database on MS SQL and THEN port it to MySQL. Unless they've got an ready made database that they think will fit our needs and then after a while port that to MySQL. But concidering the number of planning and workhours they put in to the offer, it really can't be true, because other companies had the same amount (or less) work hours for making it directly MySQL.

Re: Why does DISTINCT take so long time ??
Hi, In fact I have a compound index on (mot,date,numreponse,topic), so I assume (mot,date,numreponse) is also optimised if I correctly understand how indexs work ;) Anyway, I just wanted to run this query once, so it's not really my priority to make speed faster on this particular query (moreover putting a specific index on a table with more than 2M table will take a big amount of time, probably as long as my query without DISTINCT ;)) Jocelyn - Original Message - From: Anvar Hussain K.M.

Hi, Surely, the having clause is not redundant ( I misread it as 0). Is it not the compound index (on mot,date,numresponse) which would make the query fast instead of three single column indexes?

Re: Mysql/Php Help?
I really suggest you do a little homework and read the tutorials in both the php and mysql manuals. They are really valuable and should give you the examples you need.
