Re: MySQL or MaxDB or PostgreSQL or Interbase/Firebird or ?
Hi Mike, I've asked this question a year ago on the Borland forums but didn't get any replies. Do you know of any websites (non-programming related) that are using Interbase/Firebird for their primary webserver database? I don't mean programmer hangouts like www.mers.com or www.tamaracka.com etc., but Fortune 1000 companies who are using IB/FB on the web to serve up web pages? It would be interesting to get a list of who's using it online. TIA I have no idea :-) ... With a chat I recently had with someone from Opera Software, he told me that they recently migrated their entire my.opera.com to Firebird, but that's the only one I can come up with right now.

Thanks for pointing this out. I've compensated max_allowed_packet and increased the key_buffer.

Your current tables to InnoDB? no, the other way round: because i use the packed myisam-tables with the homepage, and so i think i have to convert the innodb-tables, in which the acutal data is worked in (added, changed, deleted), at last - for usage with the homepage - to the mentioned packed-myisam-tables. I'm pretty sure you can simply extract a DDL script via some MySQL tool and change all your table-type clauses to InnoDB.

Hi all!

Re: How boolean full-text search finds matches?
Hi! On Dec 17, Matt W wrote: Hi, Just have a couple more full-text search inquiries here. :-) I'm not exactly clear on how matching rows are found when searching for 2 or more required words: '+word1 +word2'. I understand that it can't currently know which word occurs less, so that it can be searched first -- this optimization will come with 4.1's 2-level indexes. :-) I just want to know, when it finds a match for whichever word is tried first, how does it check if the other required word(s) are present in the same row? Say that word1 and word2 are each present in 100,000 rows. 1) Surely it doesn't check the 100,000 entries for word2 for EACH word1 match to see if they're in the same row, does it? No it does not :) 2) It *seems* the best way would be to do a lookup for (word2 + rowid for word1) and see if there's a match. Is this what's done? I'm not sure it's possible though with the way the index is structured... it is possible, but it is only sensible if word1 is much more rare than word1. This could be done with 2-level indexes :) 3) Or, and I'm thinking *maybe* this is how it's done from what I've heard, does it get all the matches for word1, then for word2, and then intersect them to find ones which are present in the same row? If so, how will the 2-level index optimization change things? Will it do #2? Yes to both questions, without the word then. First, one match is found for each word. Then read_next is called for the word with the lowest rowid, etc. The advantage is that matches are found and returned earlier - a user don't have to wait for the index scan to complete. Also LIMIT, if used, cuts off more work, that is LIMIT is more effective. But when one word is much more common than the second one, it is better to do #2, and it's what I'll probably do. Next question is... a few weeks ago I was doing some test searches like '+word1 +word2'. Actually, maybe I was only using 1 word, I can't remember, but I don't think it matters. Anyway, I happened to try changing the query to '+word1* +word2*' -- e.g. adding a wild-card to the end of the same word(s) -- and I was amazed at how much faster the query was! (And no, there's no query cache; and they were both run many times so the index was cached. :-)) Can't remember how much faster, but it wasn't insignificant. Then I tried adding a wild-card to the end of words in another search (the wild-card did not make more rows match as far as I know), but that made it a little slower (I'd expect that, if anything). Is there any explanation for why adding wild-cards would make a search faster? Yes :) Looking on the description above how +word1 +word2 works, you can see that it relies on the fact that key entries for each word are sorted by rowid. But it is how MyISAM indexes work, they are always ordered by all keyparts, and rowid is always the last keypart, so fulltext index is always ORDER BY word, rowid. But when the search is done for the word prefix only, this order breaks, the index is, of course, not ORDER BY LEFT(word,5), rowid. Consider the index aa, 5 aaabbb, 10 aaaccc, 3 The workaround was to exclude prefixes from index scan whenever possible (that is in +word +pref1* +pref2* ... prefixes are not looked up in the index at all, in +pref1* +pref2* ... only the first prefix is looked up in the index) and to add a row scan (in the LIKE sense and as you described in #1), to remove half-matched rows. Thus it is sometimes slower - as more row data are read from the disk, and sometimes faster - as there are less index scans performed. Obvious optimization is to choose the most rare prefix for the scan, not the first one. It is in the todo, of course :) P.S. Sergei, if you see this, in one of your replies to my full-text suggestions back in September ( http://lists.mysql.com/mysql/149644 ), you said Another reply will follow... I never saw another reply though. :-/ It's OK, I was just wondering what other interesting things you were going to say! :-) Oops, checking... Yes, sorry.

Re: MySQL on NetWare?
Hi Chris We're running MySQL on NetWare6.5 with good performance stability. About 20GB with InnoDB and a simple replication enabled (M - S). This database will grow up to 200GB in a year (with 400 active connections). We did tests and we liked. We'll set up another 2 servers to run a 100GB database (with 300 active connections) cluster-enabled. About the file size limit, your friend is wrong. You have 2 FS with NW5.0+: - TFS (old file system), but _does_ support 4GB. - NSS 64bit file system (yes, it support files 4GB+). And it's the default filesystem since NW6.0. Our databases runs only with InnoDB, but with 21 files x 1 GB. Personally I don't like to have big files in any OS. But if I want, I can create just one file with 21GB, no problem.

RE: Comparing date fields (Delphi programmers take note)
Thanks for all those who helped me with this a few days ago (I've only now
had the chance to get back to programming).
As someone correctly surmised, I am using Delphi and connecting to mySQL via
a TQuery (actually a TZQuery, via Zeos components). What I have discovered
is that
1. mySQL doesn't like queries with date parameters (one must pass the date
as a literal)
2. the date format has to be changed to that of mySQL.
3. if one uses a table alias (p in my case), one is not allowed to use the
full table name - projects.closeddate causes an error, but p.closeddate is
ok.
So I wrote a small function (called date2sql) which turns 18/12/2003 into
2003-12-18 (complete with double quotation marks), and then in my code I
write
with query1 do
begin
close;
sql[3]:= 'where p.closeddate between ' + date2sql (edFromDate.text) + ' and
' + date2sql (edTillDate.text);
open
end;
This works as it should.

JB What are those colons?
He probably uses Delphi or C++Builder to connect to mysql via TQuery
component. TQuery has a property SQL where sql statement is stored.
The colon ':' means that fd is a parameter whose value should be
inserted into TQuery.SQL statement just before executing the query.
The solution is to substitute :fd with a real value directly by accessing
TQuery.SQL
property.
Query.SQL.Clear;
Query.SQL.Add('select ...');
Query.SQL.Add('where projects.closeddate between 01/01/01 and 01/01/02');

I very much doubt this works:
01 divided by 01 :-)
I guess you wanted to write:

Re: Comparing date fields (Delphi programmers take note)
Hi, Interesting. Thanks for all those who helped me with this a few days ago (I've only now had the chance to get back to programming). As someone correctly surmised, I am using Delphi and connecting to mySQL via a TQuery (actually a TZQuery, via Zeos components). What I have discovered is that 1. mySQL doesn't like queries with date parameters (one must pass the date as a literal) Hmmm... I do make use of parameters, but I noticed MySQL doesn't provide me with the right datatype (like Firebird or InterBase do). So I'm passing everything as a string to the parameter. :-/ 2. the date format has to be changed to that of mySQL. Well, that makes sense of course :-) 3. if one uses a table alias (p in my case), one is not allowed to use the full table name - projects.closeddate causes an error, but p.closeddate is ok. That's according to the SQL standard: if you use an alias, address the table by it's alias only.

transactions and create table (was Questions about MySQL implementation)
What is the official word on doing a CREATE TABLE inside a transaction? Can I do one without causing the transaction to commit? By experiment, it appears that 4.0.14 allows this, although, even if the CREATE TABLE is for an InnoDB table, a ROLLBACK doesn't remove the created table. It appears that CREATE TABLE caused a commit of the current transaction in 3.23.49. I'd like to create a temporary table during a transaction--mostly to be able to emulate things like subqueries and views that will come in some future production version of MySQL. I don't have a problem with the table creation not being rolled back. I tried to RTFM. I did find a note on how transactions are treated for CREATE TABLE SELECT..., but I wasn't able to find a clear statement that CREATE TABLE will no longer force a commit.

Re: transactions and create table (was Questions about MySQL implementation)
Bill, http://www.innodb.com/ibman.php#Implicit_commit: 8.7 When does MySQL implicitly commit or rollback a transaction? MySQL has the autocommit mode switched on in a session if you do not do SET AUTOCOMMIT=0. In the autocommit mode MySQL does a commit after each SQL statement, if that statement did not return an error. If an error is returned by an SQL statement, then the commit/rollback behavior depends on the error. See section 13 for details. The following SQL statements cause an implicit commit of the current transaction in MySQL: CREATE TABLE (commits only if version MySQL-4.0.13 and MySQL binlogging is used), ALTER TABLE, BEGIN, START TRANSACTION, CREATE INDEX, DROP DATABASE, DROP TABLE, RENAME TABLE, TRUNCATE, LOCK TABLES, UNLOCK TABLES, SET AUTOCOMMIT=1. The CREATE TABLE statement in InnoDB is processed as a single transaction. It means that a ROLLBACK from the user does not undo CREATE TABLE statements the user made during his transaction. If you have the autocommit mode off and end a connection without calling an explicit COMMIT of your transaction, then MySQL will roll back your transaction.

Long Query Times
Hi all, I am curious to know if the query times I'm seeing are reasonable or not. Here's my situation: I am using a database to keep up with web statistics. The table is currently growing at about 2 million records a day. The sample table I am working with has right at 4 million rows. When I execute the query below, it takes approximately 8.5 seconds to return. Is this reasonable? Because the way I see it, this time is going to get out of control after a week, or month, or year. SELECT DATE_FORMAT(time, %Y-%m-%d %H:%i) AS date, SUM(sbytes) AS bytes FROM log GROUP BY date ORDER BY date Here is some info about my system: Single Processor Intel Xenon 3.06GHz, 1 GB RAM, RAID 0 SCSI 15K RPM running MySQL ver 11.18 distrib 3.23.58 on RedHat 9. My table currently looks like this: 3 unsigned ints, 4 char(100), 1 char(15), and a datetime column. I am not using a primary key or indexes. I'm positive a better table design will drastically improve query time. My concern is the rate at which the time grows. Can someone who has worked with a table of this size let me know what kind of times I should be expecting. Any information you guys can provide will be greatly appreciated.

Re: Connector/J 3.0.9 Unexpected end of input
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Bill Ataras wrote: I upgraded to Connector/J 3.09 from 2.0.14. After some hours, the driver looses it's connection and will not reconnect (despite setting reconnect=true). The error starts as follows below. I rollback to 2.0.14 and everything is stable again. This is using mysql 4.0.16-standard. Is connector/j 3.0x production release? Yes, Connector/J 3.0.x is a production release. Perhaps you missed the following information in the README that deals with the fact that autoReconnect=true behavior has changed? The driver now has fail-over support. This allows the driver to fail-over to any number of slave hosts and still perform read-only queries. Fail-over only happens when the connection is in a autoCommit(true) state, because fail-over can not happen reliably when a transaction is in progress. Most good application servers and connection pools set autoCommit to 'true' at the end of every transaction/connection use. I need to re-work the docs to say that this applies to autoReconnect as well, however, the following troubleshooting section from the README also tells you how to handle this (and why relying on autoReconnect might not be a good idea for most people): Issue: I have a servlet/application that works fine for a day, and then stops working overnight. Resolution: MySQL closes connections after 8 hours of inactivity. You either need to use a connection pool that handles stale connections or use the autoReconnect parameter (see USAGE AND INSTALLATION). Also, you should be catching SQLExceptions in your application and dealing with them, rather than propagating them all the way until your application exits, this is just good software development. MySQL Connector/J will set the SQLState (see java.sql.SQLException.getSQLState() in your APIDOCS) to 08S01 when it encounters network-connectivity issues during the processing of a query. Your application code should then attempt to re-connect to MySQL at this point.

Thanks, Dan Dan, You don't need the Order By since the Group By is already sorting it in that order. As far as speed is concerned, you are duplicating a lot of calculations you've already done the day before. I think you need to store the results that are returned from your daily query, into a summary table (called Summary) so you only need to summarize the current day's raw data once. So just execute your Select statement and append the results to the Summary table, then archive the raw daily data because you won't need it any more (write it to DVD each day or archive it to another database). Do this once a day. So instead of working with 2 million rows a day*365 days=730 million rows, you are only adding 24*60 rows (1 for each minute) to the Summary table * 365 days=525,600 rows = 1388 times faster! Quite an improvement, don't you think? :-) Mike -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Combining tables
I have a live feed datasource that inserts into 8 different tables( but they are all the same layout only differennt regions) and i am not allowed to change this since it is from a customer. As with Oracle you can create a materialized view that will combine those eight tables into one physical table and those will be refreshed on the fly or on certain times. Is this also possible in MySQL since we want to query on one table to find the record instead off eight.

(if it could be used for production then ... i dont have to do the painfull conversions ) Sandeep From what I gather on the mailing list, MySQL-4.1.1 should be stable enough. I'm holding off on upgrading here because of the changes to the authentication system. If you want to use 4.1.x now, you have to set up your accounts under 4.0.x and then upgrade to 4.1.x. But this makes me a little nervous with regards to disaster recovery. Once a version of MyODBC that supports the new authentication system in 4.1.1 is out, I would have no problem recommending 4.1.1. Until then, you can do it, and you'll probably be fine, but don't look at me if things go wrong and you're offline for a few hours while you figure out how to restore from a backup and set up authentication again... As for the 2 queries option, I find this works quite well. In Access, you can set up 'pass through' queries, which is where Access doesn't handle the query at all - it passes the SQL straight to MySQL, and then receives the results back as a read-only recordset. You can then use this query in your 2nd query. I've found also that if you turn on MySQL's query cache, this speeds up ENORMOUSLY ... Access seems to re-issue the same query over over again for each record it finds in the other table, and the query cache handles this quite nicely :) Post back if you want help setting up pass-through queries.

Re: Regd Sub Queries
Sandeep N Seshadri wrote: Could you please tell me more about the pass through queries. i dont have an idea abt it sandeep Sure. Create a new query in Access. Instead of adding tables to the query design view like normal, simply click the 'query' menu, and select 'SQL Specific', and then 'Pass-through'. The query builder window will disappear, and leave you with a plain text editor where you can enter the SQL. Remember not to put the usual garbage that Access puts around field names, ie [square brackets], as MySQL doesn't like them. Then click the 'view' menu, and select 'Properties'. The 2nd field should be 'ODBC connection string'. Click inside this field, and a little builder icon ( ... ) appears to the side. Click the builder, and you should get your list of ODBC data sources. Select your data source for MySQL, and you're done. When you run the query, it will get passed straight to MySQL. You can edit the SQL of the query later in VB if you have to, for example: dim sql_string as string sql_string = select * from MyTable where ID=456 and thingy=3 currentdb.querydefs(NameOfMyPassthroughQuery).sql = sql_string The above code will update the SQL of your pass-through query, so when you open it next time, it will return the records you're after.
