RE: why does it not work

order by rand() didn't work back in 3.22.
if i remember correctly (if this doesn't work, you can try to search

SELECT col1,col2,RAND() as r FROM table ORDER BY r LIMIT 1;
Thanks. Now I am into another problem. I am not sure whether it is php
or mysql. Though it works in the command prompt of mysql. Below is the
snippet of my php script. What I am trying to do is to randomly display a
scroll from the special table. This happens when the page is loaded or
refreshed.
// sql statement
$searchStmt = select special.contid, special.cityid, special.curr1,
special.catalogo, special.hf, special.curr2, special.vitofferta,
special.fh, special.club,
special.stars, city.city,RAND as r from special,city where
DATE_SUB(special.periodo, INTERVAL 3 DAY) '$tdate' and
city.id=special.cityid order by r limit 1 ;
var timerID=null
var run=false
count = 10 // counter of cycles
ScrollSpeed = 800; // milliseconds between scrolls
ScrollChars = 1;// chars scrolled per time period
function Stop()
{
if(run) clearTimeout(timerID)
run=false
}
function Start()
{
Stop();
Marquee()

function Marquee()

var msg = document.forms[0].message.value;
var tmp = msg.substring(0,ScrollChars);
msg = msg.substring(ScrollChars) + tmp;
document.forms[0].message.value = msg;

count++;
}
}

Re: count(*) on different tables
is it possible to get *one* quick result with the rowcount of each table in one database, without knowing the column-names? this does *not* work: select count(t1.*), count(t2.*) from table1 t1, table2 t2 Select 'Table1' as tableName, count(*) as rowCount from table1 UNION Select 'Table2' as tableName, count(*) as rowCount from table2 ... etc Assuming that MySQL can use the UNION clause. (I haven't checked) I think MySQL actually doesn't support union. ;/ I wonder if this is so difficult.. Only getting rowcounts of different tables in one result.

Re: telnet MySQL
you should use the client to connect to your mysql since the server doesn't use the standard telnet protocol. The client is available for several OSes. For examply mysql -u peter -h grdmss57 -p Would connect to grdmss57 as user peter and would then ask for a password (which is safer than entering it on the command line) regards On Mon, 14 May 2001, Peter van Dijk wrote: On Mon, May 14, 2001 at 07:26:44AM -0700, Shtykh Roman wrote: When I try to telnet MySQL which uses port 3030 as below: telnet grdmss57 3030 I get : Trying 163.143.156.38...

How can be minimized downtime on MyISAM-InnoDB transition?
Hi, We recently decided to start switching on InnoDB for some our web projects. We have tested InnoDB on test machines and have been satisifed with results. Now the question: how can we minimize downtime on production server during transition? We see two choises: 1) change mysql server to single-user mode and change types of tables with 'alter table TABLE name=InnoDB', start mysql server to normal mode again 2) change mysql server to single-user mode and dump tables with mysqldump --quick, create new tables of InnoDB type without indexes, restore their content from dump, restore indexes, start mysql server to normal mode again. We can afford several hours of downtime so we don't want to bother with too complex solutions for this transitions like setting up replication server and so on. Some info on tables: most of them are quite small except one which has about 1,800,000 records (size of MyISAM files about 70Mb). -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- | Ilya Martynov (http://martynov.org/)| | GnuPG 1024D/323BDEE6 D7F7 561E 4C1D 8A15 8E80 E4AE BE1A 53EB 323B DEE6 | | AGAVA Software Company (http://www.agava.com/) | -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - 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: secure connection (SSL/SSH tunneling) with windows client
On Tue, May 22, 2001 at 12:51:50AM +, [EMAIL PROTECTED] wrote: I know this has been discussed a lot. I did read the mail archive and found lots of interesting info. Although I have a problem. We're developing a windows software that has to exchange sensitive data with a mySQL server. I read about implementing a SSH tunnel. It works well, although I have not found a free ssh client for windows. Even if I did, it would not be really helpful as we don't want to explain to our users they have to install a third party software that does IP tunneling in order to transmit data securely. Any suggestions? Even if SSL support was added to mySQL, I guess I'd still have to wait for SSL support in the client libs we use on windows (ZeosLib)... Hmm. If you want encryption, somebody has to add it at some point in time... For free SSH clients: you may find links via http://www.openssh.com/ The problem with SSH tunneling is that you need an account on the target machine to open the SSH connection. It has the advantage that once the connection has been established, no further overhead is added (except the actual encryption/decryption). For SSL: if you don't integrate SSL into your product, you can use the stunnel software (http://www.stunnel.org) to tunnel your connections. This works without accounts on the target machines. You may see a significant performance impact, as each new SSL connection requires a cryptograpic handshake. (Every time a connection to the database is opened. If you open it once and leave it open, that's fine. If you are using open-transaction-close cycles, its horrible. In the long run for a complete integration this problem can be tackled with session caching but it is not available for an stunnel solution, AFAIK.) http://www.stunnel.org/examples/mysql.html I am ready to encrypt every sensitive fields in the database, although I am wondering if the username and password will be transferred in plain text. I've seen somewhere that it isn't, but what kind of security/encryption is used and can we consider it safe? Both the designers of the SSH and the TLS/SSL protocols have spent a considerable amount of time to design the protocols to be secure and tamper proof (think of man-in-the-middle attacks) when correctly used and it took more than one iteration to bring it to the state it is now. I would therefore recommend to stay with these solutions.

JOIN optimization
Hi, I'm rather new to SQL (well, I had a one-year course at the university many years ago, but they didn't teach us anything practical). I did a few very simple data bases, but now I'm moving to something more serious with joins and 'group by'. The idea is to create a search engine for a battery distributor, specifying various characteristics like * who makes it (only one per battery) * special characteristics (various) * tipical applications (various) To simplify, I have the following tables: Battery: * batID (primary key) * makID * descr Maker: * makID (primary key) * mak Special: * speID (primary key) * special Bat_Spe: * batID * speID (both in primary key) Tipical: * tipID (primary key) * tipical Bat_Tip: * batID * tipID (primary key) First I want to make a list of batteries with all the carateristics they have: SELECT M.mak, B.descr, S.special, T.tipical FROM Battery B, Maker M, Special S, Bat_Spe BS, Tipical T, Bat_Tip BT WHERE M.makID=B.makID AND B.batID=BS.batID AND BS.speID=S.speID AND B.batID=BT.batID AND BT.tipID=T.tipID QUESTION: Is there a better way of writing this join ? Now I want to make a list of batteries which have caracteristics: * Special: speA * Tipical: tipA or tipB Además I want to sort the result such that if a battery has both tipA _and_ tipB, it comes first. I am thinking of doing it with temporary tables: tmp_spe: * batID (primary key) * count tmp_tip: * batID (primary key) * count INSERT into tmp_spe SELECT batID, count(speID) FROM Bat_Spe WHERE (speID='speA') GROUP BY batID QUESTION: Is there any difference between * SELECT batID, count(speID) * SELECT batID, count(batID) * SELECT batID, count(*) ? In this case, the three work and return the same result. INSERT into tmp_tip SELECT batID, count(tipID) FROM Bat_Tip WHERE (tipID='tipA' OR tipID='tipB') GROUP BY batID SELECT B.batID, (TS.count+TT.count) FROM Battery B, tmp_spe TS, tmp_tip TT WHERE B.batID=TS.batID AND B.batID=TT.batID ORDER BY 2 DESC This returns all the batteries which have all the characteristics I want, ordered as I want. QUESTION: Well, how does it sound ? Is there a better way to do it ? QUESTION: Now, I would need to get, for each battery matched, a list of all the characteristics it has. That is, if battery with batID='bat1' has tipical applications 'tipA', 'tipB' and 'tipC', can I retrieve in one shot all the batteries matched, together with the characteristics each one has, _or_ do I have to go through more temporary tables, _or_ is it better to make one query for each battery I have Well, I know that's a bit long, but it would greatly help to orientate me on how to continue... Thanks in advance for any help or hint, Olivier

Re: Remote access to MySQL with MySQLGUI on Win32
Nicolas Verhaeghe writes:
I am trying to see if I can communicate with a MySQL on Free BSD from the
MySQL GUI client on my Windows NT.
The GUI client cannot connect because the MySQL seems to be refusing this
connection. This does not seem to be server-related, but related to MySQL
itself, since, when I try to telnet in port 3306 on that server, I got the
error message:
Host my FQDN is not allowed to connect to this MySQL server
Do I have to modify something in the configuration file in that MySQL? And
where is that file on the FreeBSD install?
Thanks a lot if you can help!
Hi!
The above error has nothing to do with mysqlgui.
The above error means that you have not set up privileges so that your
user can connect from the computer on which mysqlgui runs.
Read the manual on the MySQL access system.

We have tried 2.2.x kernels and all kinds of memory configs but we are at a

Hi!
Please first check a hardware, before we try to isolate a problem.
This could be a bug in InnoDB handler, but if all is working well on
other machines it could be machine specific.

Hi!
Please can you check whether your hyperseek_links table is corrupted
or not ??
If it is not corrupted and the above query crashes again MySQL, please
compress your table and upload it to

Re: Problems with MySQL and Poweredge 6450..
Cody, did you copy the InnoDB data files, log files, and .frm files verbatim to the new computer? Have you tried wuith the same my.cnf parameters you had in the old computer? Does InnoDB crash always in the same function call? It looks like the internal data dictionary of InnoDB is corrupted. InnoDB tries to load the table definition and crashes while it is adding a column definition for the table. But if it works on another machine, that is strange. On one of our own machines where we have Red Hat 6.2 and software RAID, we have seen sporadic crashes, and sporadic failure of disk i/o. First, it would be useful to know what table it is. If you try simple queries (like fetching one row) from each of the tables in your database, for what table does it crash? What is the create table definition for that table? Have you dropped or altered the table?

So we loaded Mysql 3.23.38 onto the machine with no extra tweeks, just with the raw install from dell, setup the Innobase driver and imported our data. Once we moved the site onto the new server everything worked great, we could do super heavy queries in no time, it was great! Then a day later I was looking at the .err log and noticed that MySQL had crashed several times! Each time it crashes it restarts itself and the innobase tables fix themselves.

Re:How can be minimized downtime on MyISAM-InnoDB transition?
Ilya, ALTER TABLE should be faster: InnoDB does not have special optimization for separate index creation. Therefore the fastest way is to do the inserts directly to an InnoDB table. You should set the InnoDB buffer pool size big during the transition, to reduce disk i/o. Not bigger than 80 % of the physical memory, though. You should set InnoDB log files big, as described in the manual at http://www.innobase.fi, and also the log buffer to 8 MB, for example. Make sure you do not run out of tablespace: InnoDB tables take a lot more space than MyISAM tables. If an ALTER TABLE runs out of space, it will start a rollback, and that can take hours if it is disk bound. In that case it is better that you kill the database process and delete all InnoDB files and all InnoDB table .frm files, and start your job again, rather than wait millions of disk i/os to complete. Regards, Heikki Tuuri Innobase Oy Hi, We recently decided to start switching on InnoDB for some our web projects. We have tested InnoDB on test machines and have been satisifed with results. Now the question: how can we minimize downtime on production server during transition? We see two choises: 1) change mysql server to single-user mode and change types of tables with 'alter table TABLE name=InnoDB', start mysql server to normal mode again 2) change mysql server to single-user mode and dump tables with mysqldump --quick, create new tables of InnoDB type without indexes, restore their content from dump, restore indexes, start mysql server to normal mode again. We can afford several hours of downtime so we don't want to bother with too complex solutions for this transitions like setting up replication server and so on. Some info on tables: most of them are quite small except one which has about 1,800,000 records (size of MyISAM files about 70Mb). -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- | Ilya Martynov (http://martynov.org/)| | GnuPG 1024D/323BDEE6 D7F7 561E 4C1D 8A15 8E80 E4AE BE1A 53EB 323B DEE6 | | AGAVA Software Company (http://www.agava.com/) | -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- --- - - 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: How can be minimized downtime on MyISAM-InnoDB transition?
Ilya, actually, it may be safest that you use CREATE TABLE to create an identical InnoDB table, and then do INSERT INTO newtable SELECT * FROM oldtable WHERE yourkey something AND yourkey somethingelse; In this way you can divide the insertion into pieces, and you have better control on what is happening. After all data is inserted, you can rename tables. Regard, Heikki At 04:22 PM 5/22/01 +0400, you wrote: Thanks for info.

Re: JOIN optimization
Hi, I'm rather new to SQL (well, I had a one-year course at the university many years ago, but they didn't teach us anything practical). I did a few very simple data bases, but now I'm moving to something more serious with joins and 'group by'. The idea is to create a search engine for a battery distributor, specifying various characteristics like * who makes it (only one per battery) * special characteristics (various) * tipical applications (various) To simplify, I have the following tables: Battery: * batID (primary key) * makID * descr Maker: * makID (primary key) * mak A battery can have only one manufacturer, so you might as well add the mak column to Battery and remove Maker. Special: * speID (primary key) * special Bat_Spe: * batID * speID (both in primary key) This is a join table. It creates a many-to-many join between Battery and Special. Tipical: Do you mean Type? * tipID (primary key) * tipical Bat_Tip: * batID * tipID (primary key) From the SELECT statement immediately below, it appears that this is a join table. If that is the case, then Bat_Tip.tipID should not be a primary key. If Bat_Tip.tipID is a key, then you don't need the Bat_Tip join table. * *** First I want to make a list of batteries with all the carateristics they have: SELECT M.mak, B.descr, S.special, T.tipical FROM Battery B, Maker M, Special S, Bat_Spe BS, Tipical T, Bat_Tip BT WHERE M.makID=B.makID AND B.batID=BS.batID AND BS.speID=S.speID AND B.batID=BT.batID AND BT.tipID=T.tipID QUESTION: Is there a better way of writing this join ? Given your current schema, no. * *** Now I want to make a list of batteries which have caracteristics: * Special: speA * Tipical: tipA or tipB Además I want to sort the result such that if a battery has both tipA _and_ tipB, it comes first. I am thinking of doing it with temporary tables: tmp_spe: * batID (primary key) * count tmp_tip: * batID (primary key) * count INSERT into tmp_spe SELECT batID, count(speID) FROM Bat_Spe WHERE (speID='speA') GROUP BY batID QUESTION: Is there any difference between * SELECT batID, count(speID) * SELECT batID, count(batID) * SELECT batID, count(*) ? In this case, the three work and return the same result. In the future, if you decide to change the WHERE clause to search for two or more speIDs (e.g. WHERE speID = 'speA' OR speID = 'speB'), then the counts will be different. Decide what you actually want to count; speIDs, batteries, or rows. Even if the WHERE clause doesn't change, what you count gives you a clue as to what the statement does. Suppose you want to count rows and you use count(batID). Six months from now when you've forgotten how this works, the use of count(batID) will make it more difficult to figure out that you are counting rows. INSERT into tmp_tip SELECT batID, count(tipID) FROM Bat_Tip WHERE (tipID='tipA' OR tipID='tipB') GROUP BY batID SELECT B.batID, (TS.count+TT.count) FROM Battery B, tmp_spe TS, tmp_tip TT WHERE B.batID=TS.batID AND B.batID=TT.batID ORDER BY 2 DESC I believe that's a fluke. Since you are ordering by (TS.count + TT.count), a battery with speA and tipA can appear ahead of a battery with tipA and tipB. In order to avoid this, use ORDER BY TT.count DESC You can combine the two ORDER BY conditions to order within TT.count. ORDER BY 2 DESC, TT.count DESC This returns all the batteries which have all the characteristics I want, ordered as I want. QUESTION: Well, how does it sound ? Is there a better way to do it ? Your method looks good to me. Pretty impressive for someone who studied SQL many years ago for a period of one year. QUESTION: Now, I would need to get, for each battery matched, a list of all the characteristics it has. That is, if battery with batID='bat1' has tipical applications 'tipA', 'tipB' and 'tipC', can I retrieve in one shot all the batteries matched, together with the characteristics each one has, _or_ do I have to go through more temporary tables, _or_ is it better to make one query for each battery I have Join the last statement above to the Bat_Tip and Tipical tables. SELECT B.batID, T.tipical FROM Battery B, tmp_spe TS, tmp_tip TT, Bat_Tip BT, Tipical T WHERE B.batID=TS.batID AND B.batID=TT.batID AND B.batID = BT.batID AND BT.tipID = T.tipID You can join to the Special table in the same way. Well, I know that's a bit long, but it would greatly help to orientate me on how to continue...

Anyone have a clue ???

InnoDB tuning tips now in the manual at www.innobase.fi
Hi! I wrote a short new section 9 to the InnoDB manual at http://www.innobase.fi It is a collection of performance tuning tips most of which I have also given on this mailing list.

RE: UNIX_TIMESTAMP converts to CURRENT_DATE on a second call
Sinisa writes: - timestamp is saved in datetime format - first timestamp column is silently updated on each UPDATE What this means, of course, is that when you want to deal with your own TIMESTAMP data, you need to maintain some sort of sacrificial column (e.g. LAST_UPDATED TIMESTAMP) that can be subjected to this automatic update (and must be the first TIMESTAMP column in your table!), so that MySQL leaves your other real TIMESTAMP columns alone. Though really, this behavior should be an *option* (preferably a *per-table* option) in MySQL, not an automatic feature (i.e. assuming that any TIMESTAMP column must be a last-updated type column data). TIMESTAMP is an ANSI type with its own defined semantics, and it's perfectly valid to expect that the user may want to maintain their own timestamp data without MySQL making any assumptions about it.. -- Shankar.

Ugly output
I'm running the following: select if(substring(username,1,8)='cctcpin-', lcase(trim(leading concat(substring_index(username,'-',1), '-') from username)), lcase(username)), sec_to_time(sum(acctsessiontime)) as session from radacct where acctstarttime between '2001-04-21' and '2001-05-21' and acctstoptime group by username order by username; which should return distinct usernames and their total monthly usage.

Re: How to retrieve record-id after 'insert into'?
In order to retrieve the id you inserted and not someones's id that was inserted a bit after yours, I guess you should lock the table before your insert statement, do the insert, retrieve the id just inserted, and then unlock the table so others can operate with the table again.

bug report
Hello, I think me and my fellows here at office, found a bug in mysql. The system is: RedHat 7.0, kernel 2.2.16, on Celeron 700MHz mysql version 3.23.22 Here is the script: ( cat EOF connect test; create table test (i numeric(4), j numeric(4)); insert into test (i,j) values (1, 1); insert into test (i,j) values (1, 2); insert into test (i,j) values (1, 3); insert into test (i,j) values (2, 1); insert into test (i,j) values (2, 2); select * from test; select i, min(j), max(j) from test group by i; EOF ) | mysql -p and here is the result: i j 1 1 1 2 1 3 2 1 2 2 i min(j) max(j) 1 0 3 2 0 2 the interesting part is that if I replace create table test (i numeric(4), j numeric(4)) with create table test (i integer, j integer) , then the result is ok We have tested this script on another machine with Pentium 100MHz and RH7.0, and the result is the same. I hope this bug report will be usefull.

RE: JOIN optimization
Hi Bob,
Many thanks for your answer, I was afraid that
due to the length of the mail, it would scare
everybody...
Battery:
* batID (primary key)
* makID
* descr
Maker:
* makID (primary key)
* mak
A battery can have only one manufacturer, so you might as well add
the mak column to Battery and remove Maker.
Well, the idea was not repeating the name of the maker,
just have its ID.
Special:
* speID (primary key)
* special
Bat_Spe:
* batID
* speID (both in primary key)
Tipical:
Do you mean Type?
Well, in fact I mean Typical (typical application of the battery)
* tipID (primary key)
* tipical
Bat_Tip:
* batID
* tipID (primary key)
In fact it is like for join table Bat_Spe:
* tipID (both in primary key)
QUESTION:
Is there any difference between
* SELECT batID, count(speID)
* SELECT batID, count(batID)
* SELECT batID, count(*) ?
In this case, the three work and return the same result.
In the future, if you decide to change the WHERE clause to search for
two or more speIDs (e.g. WHERE speID = 'speA' OR speID = 'speB'),
then the counts will be different. Decide what you actually want to
count; speIDs, batteries, or rows. Even if the WHERE clause doesn't
change, what you count gives you a clue as to what the statement
does. Suppose you want to count rows and you use count(batID). Six
months from now when you've forgotten how this works, the use of
count(batID) will make it more difficult to figure out that you are
counting rows.
I think I was confused because each couple (speID, batID)
is unique. That's why the 3 forms are equivalent here.
For the last question, (list of characteristics for each
battery matched) I decided to make a query for each
class of characteristics ('spe', 'tip') since I wanted to
do some additional treatments.
Thanks again Bob, I feel more confident now.
Olivier

MySql documentation says that mysql enforces table level locking if no explicit locking is there.If I am using non transaction sensitive tables can I go ahead without providing any explicit locking?I am using myISAM.

mysqldump and locking
I have a database-driven web site that uses PHP and MySQL 3.23.38. The database is about 1 gigabyte in size. While performing a mysqldump --opt to back up the database, the web site is completely inaccessible. After doing some investigating, I believe that this is because of the --lock-tables option that is implied by the --opt argument. Every page of the web site updates a session table that is a heap table. It looks like the mysqlpdump is locking the heap table for read along with all of the other tables while the dump is occuring. Should heap tables really be locked during the mysqldump? Does anyone have any ideas for a way to back up the database without having the site be down while it happens?

Re: count(*) on different tables
UNION is currently not supported, though one workaround is merge tables, it's not quite the same thing. As to your query SELECT COUNT(*) FROM table1,table2, it is returning the expected result. Without a WHERE clause, you are getting the cartesian product of both tables (all rows from table1 joined to all rows of table2). Ansgar Becker [EMAIL PROTECTED] wrote: is it possible to get *one* quick result with the rowcount of each table in one database, without knowing the column-names? this does *not* work: select count(t1.*), count(t2.*) from table1 t1, table2 t2 Select 'Table1' as tableName, count(*) as rowCount from table1 UNION Select 'Table2' as tableName, count(*) as rowCount from table2 ... etc Assuming that MySQL can use the UNION clause.

Problems with sum() in a query.
I'm gaving a problem with adding several sums together when using a group by clause. The table I have looks like this: school_id int school_name varchar sport varchar cost_a float(9,2) cost_b float(9,2) cost_c float(9,2) The real table is normalized, figured it would make for a simpler example this way, so you don't have to tell me ;) Each school has records for several diffrent sports I'm trying to query for the total amount spent for each school with the following query. SELECT school_name, (sum(cost_a)+sum(cost_b)+sum(cost_c)) as total FROM schools GROUP BY school With the desired result school_1 125000.00 school_2 234642.12 school_3 98433.45 But I get zero's for the total column. If I query for only one school I get the correct numbers: SELECT school, (sum(cost_a)+sum(cost_b)+sum(cost_c)) as total FROM schools WHERE school='myschool' GROUP BY school If I query for a few schools (school_id3) sometimes I get unusual numbers, 17.24 for one example. I'm not sure what's happening with these queries so I have to ask. Am I doing the query wrong? Is SQL or mySQL not able to handle this query?

Sun-Solaris 2.6 binary
Hi, We are running on a SunOS 5.6 Generic_105181-25 sun4u sparc SUNW,Ultra-5_10 platform. I noticed that there is not a binary file for 2.6. Is there anyway way for you guys to generate one for us. We are a company of about 200 (?) developing GSM network software. I'm evaluating MySQL. I used the mySQL version 3.21 that I found you had a binary for the OS we are currently using. That version lacked too many features for us to use. It seems that the current version, 3.23, has most of the functionality we're looking for. Yes, I do realize that I can build from the source files. But out gnu compiler is an older version. And there is a lot of hoops to jump to get the latest version.

Replication problem
I am attempting to setup a stand by database using replication. I have a table abc on the master server that I wish to replicate to the slave server as abclive. In other words, I want the updates to be written into a database of a different name on the slave. I thought this would be easy, and I tried using the following config options in the slave my.cnf: [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock master-host=10.0.0.1 master-user=repl master-password=somepass master-port=3306 server-id=2 replicate-wild-do-table=abc.% replicate-rewrite-db=abc-abclive I grabbed a snapshot of the abc database and copied to to the datadir, renaming it to abclive. I started the master/slave and it didn't work- updates were not being propogated into abclive and the error log reported no problem. I also tried the following options: replicate-do-db=abc replicate-rewrite-db=abc-abclive but it didn't work and then I read a note which said that if you use inserts like insert into abc.field ... where you named the database in the insert (which we do) then you needed to use the replicate-wild-do-table command. But neither seemed to have the desired effect. Is there an issue with using inserts with database names AND replication with the rewrite-db ??? I went back and took out the rewrite line in the first config set above and moved the slave database back to abc, and replication worked fine. I just can't get it to replicate with a new name, abclive. Can someone please tell me how to accomplish what I'm trying to do? Our standby database will be on a machine which contains daemons that are ready to go. To set these up, I need to test them and they use the original abc database name. So during the setup, I need to have a writable database to test the setup and must have the replicated one go to a different name. Once the machine is ready to go live, the test database just needs dropped and the replicated standby can be renamed. If I can't solve the rewrite problem, then I'll be forced to setup 2 instances of MySQL simply for this reason. Any hints are appreciated... Byron Guernsey V3 Networks, Inc.

It's still in todo.

RE: mysql.sock file
Dennis, do a find / -name mysql.sock 2/dev/null to find exactly where mysql puts this file.. My rpm install put it in /var/lib/mysql/mysql.sock Find where your mysql.sock file is and make a symbolic on it pointing to /tmp/mysql.sock ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock Also check your file permissions. Make sure the mysqld user has access to this directory.

Re: configure error: no curses/termcap library found
Just a guess, but you might have to add --with-ncurses=/usr so that you provide the basedir for the curses package. Do a ./configure --help and it will list the options. I believe --with-curses or --with-ncurses is one of them. Also, I think there is supposed to be a libncurses.so and libtermcap.so without a version number and its usually a symlink the the real file (with a version number). You'll want to look at the libs you found to distinguish which are symlinks, and when you find the latest version of the library (like libncurses.so.5.2) you can symlink libncurses.so to it. Likewise with the libtermcap.

Using identical column names in seperate tables
From the MySQL Manual (13.6 Other Optimization Tips) http://www.mysql.com/doc/T/i/Tips.html Columns with identical information in different tables should be declared identical and have identical names. Before Version 3.23 you got slow joins otherwise. Try to keep the names simple (use name instead of customer_name in the customer table). To make your names portable to other SQL servers you should keep them shorter than 18 characters. I'm a little confused about this statement. I'm reading two possible tips, and I want to make sure I understand... How does keeping names 'simple' optimize my database? How does naming columns with identical information in different table the same optimize my database?

FULLTEXT built for 2 char words OK ?
We need FULLTEXT searching on 2 character length words. If we recompile MySQL to do FULLTEXT indexes on 2 char length words is it going to work OK or will such short words undo the advantages of FULLTEXT ? Also will the data files be useable by other standard MySQL binary builds or will we have to use MySQLs built for 2 char length FULLTEXT words to access the data files ? thanks, - Sam. - Do You Yahoo!?
