How to write subqueries?
Hello!
MySQL v. 4.1.11.
I'm trying to write a subquery, MySQL says Error.
select num, theme, intro
from vt_(select pnid from vt_partition where pnid regexp '^[0-9]{11}$')
order by date desc, timer desc;
describe vt_parition:
+--+--+--+-+--++
| Field| Type | Null | Key | Default | Extra |
+--+--+--+-+--++
| num | int(11) | | MUL | NULL | auto_increment |
| partname | varchar(255) | | | ||
| pnid | varchar(11) | | | ||
| timer| time | | | 00:00:00 ||

| intro | text | | |||
| text | text | | |||
| date | date | | | -00-00 ||
| timer | time | | | 00:00:00 ||
+---+--+--+-+++
vt_ is a prefix, pnid is a postfix.
And the name of the table is, for expamle, vt_01234567890.
Where is/are the mistake(s) in my subquery?
Please explain me how to write a subquery in the right way.

Re: How to write subqueries?
Hello! Many thanks to everybody who tried to help me! N.B. you should have only one pnid to make your query work (UNIQUE pnid), or LIMIT the result of the subquery by LIMIT 1. I need to do the following: Get one or more than one pnid from vt_partition and then make queries to the vt_pnid tables. The result (from all the requested vt_pnid tables) should be sorted by date and time. How to do it? The version of MySQL should be 4.1.11 or lower. It would be great if the query works even on v. 3.23.58. First off, you are not writing a subquery. You are attempting to build a SQL query using the results of another query. What you are attempting is dynamic SQL. I am not familiar with a mechanism in 4.1.11 that allow you to execute a string (or a string variable) from within a SQL statement. Damn! You're right!! I only looked at the subquery itself, not the context and I missed that his subquery seems to an expression to get part of his table name! That is definitely not valid in any dialect of SQL that I know ;-) Agree, I was wrong. :-) -- Good luck! Vladimir Please avoid sending me Word or PowerPoint attachments.

More Illegal mix of collations trouble.
Last week we upgraded from mysql 4.0 to 4.1.7. Since then some queries on newly created tables (ie created since the upgrade) are failing with the error: #1267 - Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=' I have been doing a lot of reading. (Until this problem I had never heard of a character set collation.) It looks like some database connections are specifying UTF-8 and over-ridding the default global setting of latin1. See the mysql command line tool log below to see that the variables don't match the global variables. Where do I look to see what is causing this? The /etc/my.cnf already contains this line in the [mysqld] section: default-character-set=latin1 The error message occurs both when I use the mysql command line tool from the local host (mysql Ver 14.7 Distrib 4.1.7, for pc-linux (i686)) and also from PHP on a different server (phpinfo() reports Client API version 3.23.56). When I add the following line to /etc/my.cnf on the same machine as the server runs on and connect with the command line tool I don't have the same problem but this does not fix the connections from the PHP client. (Added to the [mysql] section.) default-character-set=latin1 I don't understand how or why the default connection data encoding would be different from the default table encoding. Maybe someone can explain this to me as well. By using SET CHARACTER SET latin1; in the command line tool the problem goes away but it's silly to have to tell all my clients they have to explicitly set the character set every time they connect. What settings should be adjusted to prevent the errors from occuring? Thanks, /Chad mysql SELECT SUM( Credits ) - FROM Acct_Payments - WHERE Void = 'No'; ERROR 1267 (HY000): Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=' mysql show variables like 'char%'; +-- ++ | Variable_name| Value | +-- ++ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | latin1 | | character_set_results| utf8 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/local/mysql-max-4.1.7-pc-linux-i686/share/mysql/charsets/ | +-- ++ 7 rows in set (0.00 sec) mysql show variables like 'colla%'; +--+---+ | Variable_name| Value | +--+---+ | collation_connection | utf8_general_ci | | collation_database | latin1_swedish_ci | | collation_server | latin1_swedish_ci | +--+---+ 3 rows in set (0.00 sec) mysql show global variables like 'char%'; +-- ++ | Variable_name| Value | +-- ++ | character_set_client | latin1 | | character_set_connection | latin1 | | character_set_database | latin1 | | character_set_results| latin1 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/local/mysql-max-4.1.7-pc-linux-i686/share/mysql/charsets/ | +-- ++ 7 rows in set (0.00 sec) mysql show global variables like 'colla%'; +--+---+ | Variable_name| Value | +--+---+ | collation_connection | latin1_swedish_ci | | collation_database | latin1_swedish_ci | | collation_server | latin1_swedish_ci | +--+---+ 3 rows in set (0.00 sec) mysql show create table Acct_Payments \G

A current row updating counter for a mass Update or similar?
Hi all, I'll just get straight to the problem (simplified): Say I have the following table/columns: ID, Score, Rank 1, 20, 0 2, 50, 0 3, 10, 0 4, 5, 0 5, 97, 0 Is it possible, in a single query (using sub-queries if necessary), to give all of these ID's the correct rank... ie if such a thing existed it might look like: UPDATE table_name SET rank=(current_row_updating+1) ORDER BY score DESC; Which would, you'd hope, make the table data then read: ID, Score, Rank 1, 20, 3 2, 50, 2 3, 10, 4 4, 5, 5 5, 97, 1 But I could find no nice looking commands that would give me this (perhaps that is not possible due to the nature of the database structure and the nature of updating? Though there must be some counter for it to report back with how many rows matched, how many were updated etc.). I also tried with a sub-query which the equivalent for the above example might look something like: UPDATE table_name SET rank=(SELECT COUNT(*) FROM table_name AS t2 WHERE t2.scoretable_name.score); But couldn't seem to make it work - I received MySQL error messages with my attempts, I think possibly because I am trying to use the table I am trying to update to also pull select data from during the update - and it'd need a little adding to it anyway - if scores were equal, it'd want to default to lower ID number wins the higher rank. I can't seem to find any obvious nice way of doing this, other than the poor method of looping/iterating through with an Ordered select, and then sending individual UPDATES for each and every row received by the select (which in the above simplified example would be 6 query calls - 1 to get the select, followed by 5 seperate updates sent by PHP using PHP to know what rank # we were currently on). Thanks in advance, I hope somebody can point me to a possible solution of getting all of this with a single query as I have attempted, I'd appreciate any help on this matter. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

MySQL memory usage
Hello, On a P4-2.6Ghz, 1Gb mem server of ours, mysql keeps getting slower and slower because the database gets bigger and bigger. At the moment the database is 5.5Gb big, the biggest table being 1.1Gb. 'top' shows that mysqld is using 264M of memory. So I presume the rest is used for disk caching. How do I know for sure that mysql is using the rest of the memory, or how do I get mysql to use it all? Would an extra gig of memory help mysql, or linux, to be faster? Will MySQL put it's tables in the extra memory so it won't have to read from disk anymore? Our keycache hitrate is at 99.6% so I think the key_buffer_size is big enough, but would increasing this setting help? We experimented with doubling this buffer, but mysql got slower from it. Or could someone have a look at our my.cnf, and see if anything could be better? Here's my.cnf: port= 3306 socket = /tmp/mysql.sock set-variable= key_buffer_size = 256M set-variable= max_allowed_packet = 1M #set-variable = thread_stack= 128K set-variable= max_connections = 300 #set-variable = query_buffer_size = 4M set-variable= record_buffer = 32M #set-variable = record_buffer = 64M set-variable= record_rnd_buffer = 32M #set-variable = sort_buffer = 8M set-variable= sort_buffer = 4M set-variable= join_buffer = 16M set-variable= table_cache = 768 What I *really* need to know, is would our server get quicker from installing an extra 1Gb of ram, before we take the chance and purchase the expensive PC800-RIMMS.

create temp table
In MySQL is it possible to create a temporary table without having to specify all the properties? On SQL Server (at least via query analyzer) you can create temp tables fairly easily and the properties of each field are inherited from the regular table. Doesn't look like thats the case with MySQL, but it doesn't hurt to ask first ;) chris - 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?

multi-table join
In MySQL, I need to do a multi table join in the context of a left join. Have three tables: NAME, ADDRESS, and COUNTRY. Address contains a country code (ie CAN) and COUNTRY contains the translation (ie Canada). What I'd like to do is get all NAMES, all datat from ADDRESS if it exists, and the full country name from COUNTRY if there is an address. I tried: SELECTA.NAME, B.ADDRESS, B.CITY, C.COUNTRY_DESCR FROM NAME A LEFT JOIN ADDRESS B ON A.ID = B.ID JOIN COUNTRY C ON B.COUNTRY = C.CODE but I got a resource doesn't exist type error. Is this even possible? I know left joins can be tricky, but this seems like it should work. Maybe I have the syntax wrong? I even tried using parentheses as in: SELECTA.NAME, B.ADDRESS, B.CITY, C.COUNTRY_DESCR FROM NAME A LEFT JOIN ADDRESS B ON (A.ID = B.ID (JOIN COUNTRY C ON B.COUNTRY = C.CODE)) but that neither worked nor changed the error message.

updating some records in a table
Hi, I am new to mySQL, so I need some help. I have a table, which has record structure like this: - customer - name - register_date - expired Every day, I add some records, new customers. The field 'expired' is just a flag, either '1' or '0'. If register_date is 3 months ago then expired = 1. The format of register_date is unixtime, or Epoch. How can I update the entire database, for setting the expired field ? now = current_unixtime(); threemonths = 3 * 30 * 24 * 60 * 60; select * from table_name where register_date + threemonths now How to construct the proper select statement ? I use VARCHAR for register_date. select for i = 0 to number_of_rows do update table_name set expired = 1; I just could not think how to implement this. I need some example code how to update some records in table like in my situation. I use C ... or Perl Thanks. __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

closing database (mysql C API)
Hi,
I wrote an application using mysql C API.
If I exit my application without closing database, will it be closed automatically?
void error(int code) {
printf(error: %d\n, code);
exit(0);
}
int main() {
...
error(-255);
...
}
How to pass the mysql database connector to a function? is this correct? :
void error(int code, MYSQL db) {
mysql_close(db);
printf(error: %d\n, code);
exit(0);
}
Because I am not sure this will be correct ... should not it using pointer?
Thanks.

restricting mysql

But without using firewall :( I dont have knowledge about this. If there is no way to do this without firewall, then I will learn it. I tried --skip-networking, but then mysqld could not be started.

RE: load data infile
Hi Everyone, Many of you suggested that, in regards to my problem with LOAD DATA [LOCAL] INFILE ... , I may have permissions problems. I checked with the host and the reply was, You have access to do all commands except for the grant command. So it would appear that I SHOULD be able to load data from my laptop. But as of yet I cannot. To reply to some of your more specific questions: Yes, the file is definitely located in the directory specified. Using \\ instead of a single \ in the path seems to be a good thing, but the file is still not found. I keep getting Errcode: 2 and using perror only tells me that there's an error in my Perror code, so I have no idea what Errcode 2 is (though it is likely something telling me it could not find the file!) Was mysqld started with --local-infile=0? Uh, dunno. The host provides an interface which I started working with but I am wondering if maybe there isn't a bug in it somewhere. Probably best to write my own query window, either way all that I can provide is my user name and password, I have no control over the servers or application beyond logging in and supposedly having all but grant permission. ...have you tried using the UNC path to the file? I'm technical enough to know that UNC doesn't stand for University of North Carolina, but that's about it. I am going to assume that you are asking if I've made sure the path is the actual path and not some pseudo-thingy that windows does. Indeed I believe I have. If your question is in relation to something else, I'm open to being educated :) Thanks to Aaron Foster for the vote of confidence: Give yourself full rights - go on, you know you deserve it! I know I deserve it, but those damn hoohas hosting my site just won't give it up! And I certainly wouldn't insult toads -- they probably don't care which version of MySQL my database is on, and they LIKE bugs! I don't know which version they are running, its not in their documentation. So ... I am going to bypass the hosts administrative interface and find my own way in, see if that works (yea, one more thing to do) and maybe do a positive binary dance or some chanting. If I don't make progress on this in the next day I'm gonna brew up some damn strong coffee and INSERT the data --- gotta have data!

Replication in v4.0.2 not doing UPDATE
Description: I am using MySQL v4.0.2 and I have set up a master database and 2 slave databases, all on separate Solaris machines. The replication works fine when I INSERT or DELETE but does not perform my UPDATE statements. I have used 'mysqlbinlog' on the relay log on one of the slaves and the UPDATE statements are being sent to the slaves but they are not being executed. No errors have been generated to the error log and no errors are shown when a SHOW SLAVE STATUS is run. The slaves use replicate-do-table directives in the config file but the tables that I am trying to update are listed and I can INSERT into and DELETE from these tables that I am trying to update. The UPDATE succeeds on the master. All of my tables are INNODB type. How-To-Repeat: When I run an UPDATE statement on my master database on replicated tables it is not replicated to the slaves (even though the statement is replicated to the relay log on the slave servers).

Re: Problems with select

Between replication, the main server records logs and uses the logs to track what should be transferred to the clients... so only changed data gets replicated, which is very cool.

For 18,000 euro i could build the system myself:) My two cents /PM\ What about the customer who asks a car company to make the vehicle's tryes out of velvet? Would you go off in a huff if they refused and demand they do it? There are obviously issues here that we are not privy to; there *must* be logic behind the choice of SQLServer. Are they saying that mySQL isn't upto it? Ah but if i say i want a mysql server and costs for it they shouldnt say we can do it in mssql I think they should give me an estimate on the costs for what i want then i can discuss how to get the cost down Porting a DB takes more 'than a couple of hours'. What about the written procedures, the security mappings, the back up and recovery procs, the fallback arrangements, the testing etc. If you think E18k is a lot then ask for a detailed task plan with effort; find out what they are asking you to pay for. The DB was described as 'fairly complicated' whatever that may mean. Perhaps - and we are all guesing - there are remote data issues, views, stored procs, java and god knows what else that all needs to be integrated. Mysql has always filled my need (wich is with perl,java,php) Granted it would be better to know exactly what fairly complicated is Bottom line when you get a quote is find out what they want to do task by task and then cut it down from there.

Annoying article about MySql

I am now using MySql under not so heavy load and have not yet had any problems with it, but just want to be prepared when and if they come along.

Huntrods [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, December 08, 2001 5:24 PM Subject: Re: Annoying article about MySql Ingvar, I have not used mysql data dumps directly to restore my databases, but I take the mysqldump output and massage them a bit, then use them for restores. Basically, the mysqldump output is missing the use xxx command to change to the target database. I have a perl script that does that (and extracts the table defs to another file for documentation). I have database mysqldump outputs that were 15 megabytes (now 10 megs, as I removed some report storage from the system). I have restored my system from these dumps many, many times. I have 4 systems in use at present, a Sun E250 as the production server, two Sparc 20's as devel/test servers, and a W2K system as primary development. I have an automated backup running every day on the E250 (just a script to run mysqldump with crontab), and I FTP these to the devel machine and use them to rebuild the development databases every couple of days. I restore from the modified dump by: mysql -u root -p CurrentDbms.mysql where CurrentDbms.mysql is the output of a mysqldump with the use xxx (use database) command added as line 1. I have never had any problem. Now, perhaps 10-15 megs is not considered large. Well, we started in August with a 2 meg database, and we're adding users every day. We currently have 775 users, but may expand to over 1 before this time next year. I'll keep this list posted of any problems, but so far the performance has been exceptional. I chose MySQL based on industry hearsay about its speed. I was looking for anything at the time - as Oracle 8i has a known bug in the Solaris/Sparc install scripts that essentially prevent it from being installed by anyone except an Oracle certified DBA (turns out you have to interrupt the install, manually hack some config files, and then restart the install scripts). However, once I had downloaded and installed MySQL, I became a convert. MySQL is very robust, VERY fast, and has a very tiny footprint compared to other database products. I do miss nested sub-queries and all that, but I've found a good workaround by running the sub-query as a normal query and capturing the output to a file. Then I edit the file to perform the outer query (ususally some form of update). Sorry for the long (gradually off topic) reply - but I've had no problems with large mysqldump restores.

Converting MsSQL7 to MySQL
I am working on a project for a client that got roped into MsSQL7 by her last hosting company. I am looking for a good way to convert a MsSQL7 Database to MySQL. Anyone know of a piece of software that will convert the Database files or atleast suck from one database to the another. Thanks in advance.

RE: permissions, Help for Newbie, Nicole
Hi Nicole, I guess the first issue is to be certain that you have the correct password and a MySQL account set up. If you have a shell account try something like mysql -u[your user name] -p[your password]. Sometimes ISP's will use different passwords for MySQL than the standard log in, we often do. Aside from that, I just can't help but mention the security risks PHP nuke has. We looked at it but finally settled on eZ publish. In fact we liked it so much we are now a certified eZ publish host. Double check your MySQL user and password and try logging in through the shell, or PHPadmin (you may want to check that out too) or a third party client running locally like netadmin if your ISP allows it.

My web host says that it is my problem with the program (which of course they do not provide support for). But it seems to me it's their problem, an access issue. My guess would be that they need to set up access/permission for me. Please inform me if my thinking is wrong here. If so, would this script be what I should recommend that they try?? mysql GRANT SELECT, INSERT, UPDATE ON client_db.* TO db_user@localhost IDENTIFIED BY 'password'; Thanks for your time, Nicole - 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?

socket questions
Hi, I recently had some questions about converting files and haven't had the chance to work further with it or thank everyone for the help. So thanks a lot.I found that my application needed to have a dedicated MySQL installation. There is another version of MySQL running on this machine (RedHat 6.2 MySQL-3.23.6 and 3.23.8). I got it compiled correctly and configured it for a different port and owner. The daemon started. In the configuration options I set a new name for the socket mysql-lpmo.sock . I was thinking that the socket would be automatically created, but that doesn't appear to be the case, Does anyone have any information on the correct procedure for doing this?

RE: specifying a delimiter
Hi Paul,
Thanks for the help. I was hoping to accomplish this with MySQl, but in the
end a script works just as good and this is just the first of several I am
using. For what it's worth I ended up using sed. Here is is if somone else
could use it:
sed s/ /|/g
^This is a tab, not spaces..
I am now confronted with another problem. I need to also provide a CSV
version.
I need to use , seperated and protected text. I have a copy of phpMyAdmin
that will
export to this format, but I need to use this at the shell.
I haven't yet dug into the script to se if this done with PHP or MySQL. I am
thinking it is probably done with PHP.
I noticed a mention of MySQL being able to set a delim in the docs but alas
they never actually say how.
Finally, I considered using awk for this but I am running into a problem
there as well
since 's are used to protect text. For instance
awk '{print $1,$2} would print the fields correctly if not for
the issue.
A shove in the right direction would sure be appreciated.
Thanks,
-Eric

something like :

mysql -uroot -ptest database sql
Then I run that script like this:
./script.sh output.txt
Any delimiter is ok except for tab. Is this possible?
Thanks, in advance,
Not with mysql by itself. You can use sed or tr to change
the tab in mysql's output to something else. The syntax for
tr varies among systems, but on one of my systems (RedHat),
both of these work:
mysql sql | tr '\t' :
mysql sql | tr '\011' :

Er, I should have been more specific and said both of these work to
change tabs to colons. Substitute whatever other character you wish.
Sorry.
