how to 'tell' the select what to omit
Hallo suppose you have a table with great number of columns (20 or 30), and you would like to specify every one but two or tree columns in a SELECT statement. Is there a way to specify only those two or tree columns for omission (which would be the 'short' way to do the job) instead of specifying every column that needed (which would be the 'long' way to do the job). Example: The 'TName' table header: id | name | surname | dateOB | idSCHOOL | idCITY | idSTATE | sex | idParent1 | idParent2 | interests | weight | height | age | auditDate | idAudittor | You need every field except the 'dateOB' and 'idSCHOOL' Ordinary select wold be: SELECT id,name,surname,idCITY,idSTATE,sex,idParent1,idParent2,interests,weight,height,age,auditDate,idAudittor, FROM TName It is too long expression, is there a way to specify only 'dateOB' and 'idSCHOOL' - the two column that are unwanted in the result set - in order to make the SELECT shorter? The SELECT should return every column but the specified ones.
Problem reading my.cnf
Hi, I have just upgraded mysql server version from 4.0.13 to 4.0.14, from FreeBSD 5.1 ports collection. Before upgrade mysql command line client could read password from /etc/my.cnf file and I could use mysql without supplying -p option. But after upgrade it could read password only up to # sign. For instance in /etc/my.cnf file: [client] password= test#istest$ port= 3306 socket= /tmp/mysql.sock When I issue command mysql --print-defaults it prints: mysql would have been started with the following arguments: --password=test --port=3306 --socket=/tmp/mysql.sock --no-auto-rehash Is this a bug of mysql command line client or it is something different? Is there anybody who solved this already? thanks in advance, Ganbold -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

RE: replication question
Replication just executes the commands in the binary log (i.e INSERT, UPDATE, DELETE, ...). So if you make sure that you do not issue a DDL for creation/altering in the master DB, everything should work fine.

Security related! Not possible to hide table structure. I couldn't find..... ?
Hello, Think that we have a database named DATABASE1, and table named TABLE1, and fields named FIELD1, FIELD1,FIELD2,FIELD3,FIELD4 You want to give a specific permission to a user named USER1 For ex, you give only SELECT permission to USER1 for FIELD1 and FIELD4 in TABLE1 and DATABASE1. and you did not assignany other permission to USER1. Now everything is OK! USER1 can only select FIELD1 and FIELD4, and can not see data or change or etc.. to FIELD2 or FIELD3.. So we think that everything is OK! But, USER1 is still able to see the table structure of TABLE1. He see fields which i don't want him to see! As i searched internet related to this topic i couldn't find any satistfactory solution to this one. Anyone has idea to prevent USER1 to be able to see table structure and only permission to SELECT FIELD1 and FIELD4 as i assigned? Also there should be some default error message for these users when they try to select from another field. why? Because if my first question gets answered and solved, then, USER1 can try to SELECT FIELD3 FROM TABLE1.. .and it will say something like "you have no permission for FIELD3" insted of this, it can be "This field does not exist"..

If you give access rights to a user on a DB, he will always be able to see the table structure. This is how it is implemented in MySQL (which does not mean that I like this).

Replication and LOAD DATA INFILE MySQL Max 3.23.56-1
Hello, After recently replicating using the stop databases and copy innodb and mysql files method, things were fine... Until the slave thread stopped complaining about duplicate rows after one of our developers did a LOAD DATA INFILE operation on the master. Unfortunately the insert's are into a table using AUTO_INCREMENT as well and this may be compounding the problem. I have read the docs, but it's sort of unclear, does LOAD DATA INFILE work in a replicated 3.23.56-1 setup, only under certain circumstances, or not at all? Your help is greatly appreciated.

table error 127
I have mysql setup on two computers with identical databases. When I run a group of queries on the one computer I get back an error 127 which I checked on an it appears to be a table corruption error. On the other computer, the queries run fine. Since I had all the data for the table in question in a data file, I just dropped the table and recreated it. The error still appeared. Any suggestions on what to try next? The only other thing I can think of is to compare the mysql versions to see if I have an older version on the other computer.

Your primary query has no where clause, so you are setting all Value to a value from a random record for the most recent date. Hardly looks like a 'bug' to me. And why the cross post? Daniel Kiss wrote: Hi all, I have two tables CREATE TABLE main ( ID int not null, Value int ); CREATE TABLE sub ( mainID int not null, KeyDate date not null, SubValue int not null ); I want the Value field in the main table to be set to the latest SubValue in the sub table. I suppose this syntax should work. But it does not, and sets the Value fields to incorrect values. update main set Value = (select SubValue from sub where main.ID = sub.mainID order by KeyDate desc limit 1) Any ideas?

what is so bad at seeing the table structure? i mean to work with the table, you need to know the fields and their types to avoid syntax errors. and what should happen on a SELECT * FROM...? do you want to see nothing, because it would let the user know about the structure, or all fields, as normal? or what about sql admin progs like phpmyadmin? i think they rely on getting all the fields to show a table. i've heard about table views in mysql 5. would that already be a solution for that? -yves -Ursprüngliche Nachricht- Von: Rudy Metzger [EMAIL PROTECTED] An: [EMAIL PROTECTED] Gesendet: Montag, 4.

RE: Order by umm OR?
Hey Kevin, Ya I know thousands of items in the IN clause is not a good way, and it takes a while but from all the other process I've tried it has been actually the quickest (join for instance takes longer on my tests). Like yourself though I'm quiet clueless on what another way to do this might be even though I believe there should be one. As it is right now I simply think I need a faster server that could handle such processes faster. It gets even worse when I try to do a SUM() when dealing with thousands of records.. Now that takes a long time. But other then creating cache type tables when that happens I don't know a work around for that either.

If you can be sure that no one is accessing the tables through mysqld while you run myisamchk, you only have to do mysqladmin flush-tables before you start checking the tables.

Re: SubQuery bug in 4.1
Mark, I agree there is no reason for the sub-select. I'd make one change in response to the original request - asking for the most recent item. Take Mark's statement and suffix AND m.KeyDate = MAX(m.KeyDate); to the last WHERE statement (see example). UPDATE main m, sub s SET m.Value = s.subValue WHERE m.id= s.mainid AND m.KeyDate = MAX(m.KeyDate); I'm not sure if this is a bug with MySQL. What are the results you're getting? The sub-select you wrote will retrieve multiple rows (assuming you have multiple rows for a sub.MainId, which I assume you do by the requirment for the most recent item).

Re: Query Cache slow downs?
Hey There, Our MySQL database server is: 1. Sun Ultra Enterprise 4500 System Chassis with SBus I/O 4. 6 System Boards, each with 2 UltraSPARC II 400 mhz CPU's and 2 GB's of memory (12 CPU, 12 GB memory) 2. 1 SBus I/O board, with SCSI-2 and dual fibre channel interfaces on it. 3. The SCSI-2 interfaces are connected to an on-board SCSI disk board that has 2 9GB SCSI disks that are mirrored. This is the boot disk for the system. 4. The fibre channel interfaces are attached to an external Sun A5000 enterprise network chassis, which as 14 * 9GB discs setup in RAID10. 5. Solaris is Solaris 8, latest patches. 6. We're running MySQL using the alternative LWP threading library that ships with Solaris 9 as standard and is backported to Solaris 8. We find that thread creation time is a lot faster with this version. Altogether, cost for this machine was -about- $15,000 USD from Solar Systems (refurbished). I highly recommend dealing with Solar as it's easily the cheapest way to get big iron. http://www.solarsys.com MySQL itself is the 64-bit Solaris MAX version, pre-compiled from MySQL.com. We're using InnoDB tables, with an 8GB InnoDB buffer cache. Right now (3:00pm on Monday), we're doing -about- 1500 queries per second, so by the evening, we'll be pushing 2500 or so. Anything else you want to know, let me know.

Can't start up - access denied to root
I am fairly much a beginner and have probably done something wrong but version 4.0.12 will not let me in. I have been using MySQL (via MySQL Front and PHPMyAdmin as interfaces usually) on a Windows ME PC with Apache, all just for learning databases, SQL and PHP. I learn slowly since I have to do a lot of other things but it has gone reasonable well. As part exercise and part for use I have been building a small database. I did nothing on it for a couple of months for various reasons. Today I accessed the database in MySQL, typing in a password which I set up. The version running is - max. I tried to add some data from a prepared text file (which I have done several times before) and got the response that this version of MySQL does not recognise this command (ie import text file data.). Which was odd. Same response in both interfaces. It has previously worked nicely in either of MySQLFront or PHPMyAdmin.(4.3) so I assumed maybe the MySQL had becomedamaged - so I uninstalled it and reloaded it (leaving the data files untouched). Now I cannot get in at all and it simply tells me that error 1045 - access denied for user root 127.0.01 which leaves me stumped. Meanwhile WinMySQLAdmin sits in the tray at the bottom and after this error message seems to shut down. [Other possibly pertinent information, or not, is that since I last used MySQL I have loaded various other bits of software such as Open Office, Mozilla and more, in case some conflict is the reason.] So - please excuse what is probably a rather basic question but can anyone suggest what I should explore to get this going again?

Oddly, it works, but the following does not: mysql create temporary table x (y int, z int, q int, index (y, z)); insert into x values (1,2,3), (3,4,5), (5,6,7); explain select * from x where y = 1 or z = 1; Query OK, 0 rows affected (0.00 sec) Query OK, 3 rows affected (0.00 sec) Records: 3 Duplicates: 0 Warnings: 0 +---+--+---+--+-+--+--+-+ | table | type | possible_keys | key | key_len | ref | rows | Extra | +---+--+---+--+-+--+--+-+ | x | ALL | y | NULL |NULL | NULL |3 | Using where | +---+--+---+--+-+--+--+-+ 1 row in set (0.00 sec) On Mon, 4 Aug 2003, Joshua Spoerri wrote: That doesn't seem to work (and not with bigger table either): mysql create temporary table x (y int, z int, index (y), index(z)); insert into x values (1,2), (3,4), (5,6); explain select * from x where y = 1 or z = 1; Query OK, 0 rows affected (0.00 sec) Query OK, 3 rows affected (0.00 sec) Records: 3 Duplicates: 0 Warnings: 0 +---+--+---+--+-+--+--+-+ | table | type | possible_keys | key | key_len | ref | rows | Extra | +---+--+---+--+-+--+--+-+ | x | ALL | y,z | NULL |NULL | NULL |3 | Using where | +---+--+---+--+-+--+--+-+ 1 row in set (0.00 sec) mysql quit Bye $ rpm -qa | grep -i mysql perl-DBD-MySQL-1.2216-4 MySQL-devel-4.0.13-0 MySQL-client-4.0.13-0 MySQL-server-4.0.13-0 MySQL-shared-compat-4.0.13-0 (Thanks for your help) On Mon, 4 Aug 2003, Alexander Keremidarski wrote: Joshua, Joshua Spoerri wrote: Which version is targetted for optimization of OR searching on two keys, that is, select * from sometable where f1 = 123 or f2 = 123, as described in http://www.mysql.com/doc/en/Searching_on_two_keys.html ?

Re: Searching on Two Keys with OR?
Have you tried using the UNION statement? That worked great for me. So, something like: (select * from sometable where f1 = 123) UNION (select * from sometable where f2 = 123) ? -- Rudi Benkovic [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: Books advice
Jeff, thanks for our .02. I'm about done with my second SQL book so after reading your words the company just bought mePauls Mysql book. Thanks for your opinion.

I started reading the 1st version of Pauls' MySQL book online a week or so back using my account over at 'Safari', once I read a little and decided that I was genuinely interested in this MySQL 'thing', I went over to Barnes and Noble with intentions of getting a hard copy of the 2nd edition of this book.. well.. I ended up leaving the store with a copy of 'Mastering MySQL' by Sybex instead. I returned that book yesterday and picked up the 2nd Edition of MySQL :-). I initially chose the 'Mastering MySQL' book pretty much due to one reason, and that the size of the MySQL' book was a little intimidating. But once I got home and started reading the Sybex book I realized why Pauls' book is so long, it is impossible to cover the amount of content necessary to get a good grasp for Mysql without using a lot of paper :-). The Sybex book made a lot of assumptions and didn't go into what I felt was very thorough detail on any subject (my idea is that this is a great book for the experienced DB admin), while Paul takes the time to explain each subject and every detail very thoroughly. Thanks Paul, I just started this book but I'm already very impressed. Again.. all of this is just my $.02 and I am VERY new at all of this DB stuff Jeff -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
post install of 4.0 complications
Hello- I just installed mySql 4.0.14-0 onto my redhat 9.0 based laptop. Everything works fine except that there are ten copies of mysqld running. I have removed the /etc/my.cnf file, changed the file, restored the file and nothing changes the number of daemons running. Another guy I worked with installed the same rpms from Mysql.org and ther is only one daemon running. Any suggestions would be appreciated. Thanks, [EMAIL PROTECTED]
Fw: table error 127
Even though we don't know what exact query produces this, is there a way to raise it up to the MySQL team to take a look at? It seems to be more than a random occurrence. Thanks.

I actually have set up a cron to check/repair tables hourly because of this. The following diagnoses have been suggested, but I would bet it's an obscure MySQL bug: 1. Kernel 2.4.18 IO problem 2. Another shared library linked to MySQL (I use RPMs) 3. RAID issue causing corruption Unfortunately I haven't been able to pinpoint which query causes the issue so I can't report a bug.

The only other thing I can think of is to compare the mysql versions to see if I have an older version on the other computer.
