Any function to convert string to integer?
Hi all. Anybody knows a function or some way to convert a string to a integer? I've looked in the manual and I haven't seen anything. I need it to order a query by a column which contains numbers but the type of the column is varchar. I want to convert the values to integer before ordering the query.

Index Create Speed
Dear List, I have a (standard table handler ) table defined as follows : CREATE TABLE fact0 ( d0keyINTEGER, d1keyINTEGER, d2keyINTEGER, val INTEGER, filler VARCHAR(200) ); I then LOAD 300 rows into it ( about 350Mb) This takes about 2m30s on my ( fairly old ) hardware ( I think this is quite fast ).

Re: Primary Key pairs and auto-incrementing
On 29-Aug-01, Paul DuBois wrote: Create a single PRIMARY KEY that consists of the two columns chapter and section, and make section an AUTO_INCREMENT column. When you insert rows, set chapter to the proper chapter number and section to NULL. This will cause MySQL to generate independent sequences for each chapter.

There's nothing about it in the changelog for 3.22.25 in the documentation, and the only reference to this behavior I've been able to find in the manual is this (from the chapter on MyIsam): Note that when an AUTO_INCREMENT is defined on the end of a multi-part-key the old behavior is still present.

Hi all, On the subject of licensing: I've seen the discussions around this topic and would like to approach it from another angle. Until recently I were a student and if it weren't for the free distribution of mySQL I would have had problems. On the other hand I will be the first to - as soon as my budget allow - pay to get the added resources, I think it's only fair to the developers and us. It will also allow them to keep developing / maintain mySQL to its current standard. Thank you all at mySQL for the great product. I am new to mySQL but like it alot.

discussion: mysql licensing issue and funding issues
Hi! Neil == Neil Zanella [EMAIL PROTECTED] writes: Neil I would like to comment on the following mysql.com question Neil We have made our product available at zero price under the GNU Neil General Public Licence (GPL), and we also sell it under a commercial Neil licence to those who do not wish to be bound by the terms of the GPL. Neil Out of curiosity, how does the second statement Neil not violate the GNU GPL? It seems like the GPL Neil can be bypassed by keeping two identical copies Neil of the source code, one under the GNU GPL bundled Neil with the GNU licence file called COPYING, and Neil another bundled with a proprietary license file. Neil Since the two source files can be considered as Neil being updated separately the two licenses can Neil be kept alive concurrently. This approach which Neil as I see it is perfactly legal (as long as it Neil is made clear which is the GPL'd release and Neil which is the proprietary release on the download Neil section of the mysqld.com web site) can lead Neil to forking. In particular, contributions made Neil to the GPL'd source code cannot be applied to Neil the proprietary source code unless the contributor Neil explicitly states that the contribution goes Neil to both the GPL'd software release and the Neil proprietary source code simultaneously. cut How we do it here at MySQL (And according to what I know, this is identically to how FSF does it): All files in the MySQL distribution that is part of the core MySQL server clearly states that MySQL AB has the copyright to this file. Patches that are emailed to us for these files that just cover a few lines are not considered 'copyrightable work' and can thus be applied both to the GPL and proprietary version of MySQL. (See http://www.gnu.org/software/gcc/contribute.html for details about this) In other words, we don't have to change the copyright text of the file just because someone asks us to do a small change to the file. For larger patches we ask the author for a copyright assignment/shared copyright before applying the patch (just like FSF does). Another issue is that most patches, from outside sources, that goes into the core server are rewritten by me to be more in line with the rest of the MySQL code. For source that doesn't affect the core MySQL server (like the InnoDB or Gemini table handler or patches to the MySQL clients) we don't require a copyright assignment. cut Neil I do not believe that the mysql.org folks have the Neil experience to improve on mysql otherwise they would Neil have started theirsql from scratch. For this very Neil reason I would urge mysql.com and mysql.org to come Neil to some compromise that would avoid the uglyness of Neil what I deem as unnecessary code forking. Let us not Neil have two separate code versions of mysql. Neil Let us all cooperate. The main problem with mysql.org is that it clearly violates our trademark and other rights. If we would accept mysql.org we would put our trademark on risk and this could seriously affect our future possibilities to do business. Another problem with mysql.org is that this is driven by NuSphere, who don't have any rights to copy, modify or distribute MySQL (because they have violated the MySQL GPL license). This also makes it hard for us to work together with them. We have also tried to talk with NuSphere to solve our issues but so far in vain. During the two talks we have had with NuSphere after mysql.org was launched they have just said they are note authorized to talk about anything that is mentioned in the lawsuits (like the usage of mysql.org). It's a little hard to sort out things when one of the parties refuses to talk about the main issues at hand. Neil Also, how is mysql.org's funding strategy any better Neil than mysql.com? The two parties should perhaps merge. Neil Having two mysql's will simply weaken mysql's Neil popularity if there is no cooperation among Neil the two parties. I personally don't see any need for a mysql.org; This site doesn't provide anything important that mysql.com doesn't or couldn't provide. I you want us to help avoid confusion, I would urge you to help us to change those few links that are still pointing at mysql.org to point to mysql.com.

Replication: Push by Master or Pop by Slaves ?
There is an issue that confuse me a bit, altough it is not important for an operational point of view: From the manual: The master server keeps a binary log of updates and an index file to binary logs to keep track of log rotation. The slave, upon connecting, informs the master where it left off since the last successfully propagated update, catches up on the updates, and then blocks and waits for the master to notify it of the new updates. So, it seems that is the master that pushes information to the slave(s) But I can also read: MySQL replication is based on the server keeping track of all changes to your database (updates, deletes, etc) in the binary log and the slave server(s) reading the saved queries from the master server's binary log so that the slave can execute the same queries on its copy of the data. Here, seems that are the slaves that pop data from master. So where is the truth ? Is the master that pushes or the slaves the pops ? Or it is a combination of the two ?

MySQL Replication
Has anyone tested dropping a master database? I have dropped the master database that was replicating just to see how it would affect the slave. The slave kept its data. What would the proper proceedure be in this case? I wouldnt be able to snapshot the slave and then port the snapshot back into the master, the bin logs would be messed up then. If I was replicating multiple databases on the master (bin logging multiple databases) and I had a slave only replicating one of those databases, I wouldnt be able to just remove all the bin logs and start the process over again without losing the rest of the replicated databases. A note: Nothing occurs in the error log or in SHOW MASTER STATUS on the master when a database is dropped that it is supposed to be replicating. Does it not realize that the database is not there? If I was only replicating one database (bin logging one database), could I just port in a copy from the slave, remove the bin logs and index(or modify it in some way) from the master, do something with the master.info on the slave and then let it go from there? Has anyone ever been through this scenario? (Luckily I am only testing these things and I am not on a live database!)

mysql_connect () and mysql_pconnect are not recognized ! Pls help.
Hi,
I'm running mysql MAX 3.23.41 on LinuxPPC, everything was installed from
an RPM.
My problem is whenever I try to call mysql_connect (), from a php3
script, I got the error function not found or misconfigured
The script is a simple form, that passes the data to be added to an
empty database, with an empty table, both the MySQL server and Apache
reside on the same machine, and because it's just a test, I'm entering
as root.
I am developing a more complex script , but I need to solve the
connection problem first
BTW ifyou define a var $link = mysql_connect ( localhost ) or ; ,
which is the correct syntax ? localhost or 'localhost' ?
Why is the command failing ??? From the console it works
BTW The server is on a static IP without a DNS, is it correct to set
mysql_connect (xxx.xxx.xxx.xxx) or ('xxx.xxx.xxx.xxx' when you are
running as localhost
Thank you
Regards,
Rick

mysql (command line program) enhancement request
I use MySQL a number of different ways: the C API, from PHP, from the command line, and often from shell scripts run by other users or from crontab entries. The latter two uses present a couple of problems that could be fixed easily through some minor changes to the code for the mysql program (mysql.cc). I'd like to see the following 2 changes: (1) Blank out the password in the environment variables while running for security. Otherwise, on any system where one can run a ps command (most Unix derivatives), any user can easily see the password when it is given on the command line to the '-p' argument. As there is no other reasonable way to provide the password, this is a common problem. The C/C++ code to do this is simple, small and efficient. (2) When running in a batch mode, one usually wants to know if the command worked or not. The default is to tell the user absolutely nothing (example 1 below). Adding the '-v' (verbose) flag gets the user some feedback -- the SQL that was submitted -- but says nothing about success (example 2 below). Adding a second 'v' (-vv) adds the results of the command to the feedback (example 3 below). This seems completely backwards. I know what SQL I submitted; I want to know if it worked. I'd like to see the meaning of the '-v' and '-vv' flags reversed, giving the results with the first 'v', and then echoing the SQL along with the results with the second 'v'. Example 1: 49 hostname:~ mysql -pmypass -e 'Update foo Set val = 1 Where id = 1;' temp 50 hostname:~ Example 2: 50 hostname:~ mysql -v -pmypass -e 'Update foo Set val = 1 Where id = 1;' temp -- Update foo Set val = 1 Where id = 1 -- 51 hostname:~ Example 3: 51 hostname:~ mysql -vv -pmypass -e 'Update foo Set val = 1 Where id = 1;' temp -- Update foo Set val = 1 Where id = 1 -- Query OK, 0 rows affected (0.00 sec) Rows matched: 1 Changed: 0 Warnings: 0 Bye 52 hostname:~ - 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: MERGE TABLES
I have been playing around with merge tables. You MUST have the columns and indexes in the same order. Eg.

Virtualizing MySQL
Hi all, I am in the process of creating a Virtual Server - and pretty much all aspects have been completed to my liking. This includes web / mail / ftp and ssh. The next hurdle is virtualizing MySQL, and I would like to do this by sharing the same MySQL server across multiple chrooted clients. This way, they can have unlimied databases / tables under their userID without looking at, or disrupting, any of the other clients in their chroot. I am also rather new to this, so please feel free to point me to a URL which may help. I've tried though - couldn't find anything relevant to my cause. I appreciate your time.

Storing the mysql data in a different location

I do the mysql_install_db command and the requisite tables are installed in my new data directory, the message states that it is starting with the data in the new directory, then the server stops and the error message from the error log is : /usr/sbin/mysqld: Can't find file: './mysql/host.frm' (errno: 13) This file in fact exists in the new data directory as well as the /var/lib/mysql directory.

Re: MERGE TABLES
Monty helped me with this, and this is my understanding. Regardless of what order you generate the keys, MySQL puts the primary key first, then the UNIQUE keys, then the others. When you add a new UNIQUE key, it puts it after the primary key but before the other existing UNIQUE keys. In your case you have only non-UNIQUE keys in the merge table so you just need to add them in the same order as is in the dataN tables and MySQL will maintain the order: ALTER TABLE all_records DROP INDEX id_kex, DROP INDEX catalog_key; ALTER TABLE all_records ADD INDEX id_key (id_key), ADD INDEX catalog_key (catalog_key); --Bill Johnny Withers wrote: Well, I don't know if you can specify what order to put these in, but mine just happen to not be in the same order: mysql show index from all_records; ++-+--- --+-+---+--- --+--++ | Non_unique | Key_name| Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | ++-+- +-+---+--- --+--++ | 1 | catalog_key |1 | catalog | A | NULL | NULL | NULL | | 1 | id_key |1 | id | A | NULL | NULL | NULL | ++ +--+-+---+--- --+--++ 2 rows in set (0.00 sec) mysql show index from data1[,2,3,4,5]; ++-+--- --+-+---+--- --+--++ | Non_unique | Key_name| Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | ++-+- +-+---+--- --+--++ | 0 | PRIMARY |1 | id | A | 93 | NULL | NULL | | 1 | catalog_key |1 | catalog | A | NULL | NULL | NULL | ++ +--+-+---+--- --+--++ As you can see, the data1,2,3,4,5 tables that make up the 'all_records' table have a primary key defined on ID.

COUNTNULL function
Evening Gurus, I have a small problem that I've beaten to death the past 2 days. I am trying to get the value of a row, and update another table accordingly. The data within the row is either a 1 or 0. My issue is in trying to increment a count for both 1's and 0's. In other words, I want to SUM up all the 1's and update a table with this sum. I also want to sum up all the 0's and add this total count to the table as well. This can be accomplished in a long query, or in through a language..what I am trying to accomplish is to get the total sum of each value without using a WHERE clause. Something akin to: SELECT ... SUM(bool_was_connected), COUNTNULL(bool_was_connected), etc... the SUM will sum up all non-null values. The COUNTNULL would sum up all rows which have a value of 0. Does anyone have a UDF for this function? I currently don't have room on my laptop to download the mysql source code in order to write this up.

RE: COUNTNULL function
Calvin, Maybe I'm just confused (fairly likely), but it appears that you are confusing 'null' with zero. If you actually want to count all values including nulls, COUNT(*) will do it. If you want to count NON nulls, COUNT(a_field_name) does it. SUM(a_field_name) returns the sum of all non-null values for a_field_name. Appropriate WHERE, IN, or NOT IN clauses combined with a version of the COUNT and/or SUM functions should give you the results you need.

Re: COUNTNULL function
Yes. A feature of MySQL is that it returns 1 for true and 0 for false. When you select ... you can put logic tests and sum up the number of true values. In the case of bool_was_connected=0 will have a value of 1 when it is true and then you sum up the results. You could also do something like: SUM( bool_was_connected IS NULL ) SUM( boul_was_connected IS NULL OR boul_was_connected=0 ) and do on. Just put the condition you want to be true and count in the SUM(). b. [EMAIL PROTECTED] wrote: Thankyou kindly Bill. Just to verify, SUM adds up values. My data is only 1 or 0.

Re: COUNTNULL function
Evening Jay, I'm still abit new to MySQL. Spending the last 6 months I have worked with it more on my CGI development, than good SQL query practicing. My technical jargon is lacking. In laymens terms ( I know no other at this point in time ) I have a row that has '1' or '0' in it. I'm trying to do: What is the total number of '1's? What is the total number of 0's?

Re: Virtualizing MySQL
The short answer is that you can't, if you're using a named pipe (/tmp/mysql.sock, or some such). That would require every user having their own installation of MySQL, which may be what you want. Why not have the users connect via TCP/IP, and just set permissions correctly? They would be able to list the other databases on the server, but if permissions are set correctly, they will only be able to have access to their own databases. Hope that helps. j- k- On Thursday 30 August 2001 12:21, Mustafa Hashmi wrote: Gerhard, Thank you for your response.

because I dropped the Celegans.rep tables:!!!
mysql drop table rep;
Query OK, 0 rows affected (0.05 sec)
and dumped them again via network from master site, so I got:

I managed successfully to run myisamchk -rq on it, myisampack and again
myisamchk -rq. So now I can only tell you that broken datafile can cause
myisamchk to ask for too much memory. :(
This is on master site:

and also 19223 lines.
So unfortunately, I don't have the broken table anymore, only the
screen dumps (size od .MYD and .MYI differed). It seems the
broken datafile had 6 bytes more, broken index was much smaller.
That's all I can tell you. ;)
Maybe it helps.

Re: Virtualizing MySQL
Thanks for the response Joshua, That is an option - however not one I would be very comfortable with. I have a similar setup for virtual hosts generally - wanted something more flexible and powerful for a virtual server implementation without taxing the actual server too much. For example, the mail server (qmail) is not chrooted as such - however pop is chrooted via tcpserver, delivering messages to users in a virtual env. SMTP works the same way, chrooting to say /home/user/etc/tcp.cdb to check relay. Unfortunately, I know little about the actual how-does-it-work part of MySQL and need some direction :) I am going to try something in the next 3-4 days and hopefully I'll post a positive outcome. If this works, I'll write a HowTo :) Thanks again for your response. Mustafa. OS: debian-2.2.19 - Original Message - From: Joshua J.

Backing up a MySQL database on a remote server
I'm new to MySQL and I'm sure this has been covered, but I can't find it so I'll ask here. What is the best way to backup a MySQL database that is hosted on a remote server. Our web site is hosted by a hosting company and they configured MySQL. I want to backup the database periodically. I've tried using PhPMyAdmin to get data dumps, but the databases are quite large and the browser times out before the file download begins. How can I connect to the MySQL server from my Win2000 machine and perform a dump to my hard drive? Also, what is the best way to reverse the process and restore the dump from my hard drive to the remote server. I apologize if this question is obvious. I've looked in the documentation, but haven't been able to figure it out. Thanks in advance for the help.

Replication stalls
Greetings,
We're having some problems with our one way replication stalling.
There are no errors in the errors logs, and the status reports seem to
indicate things are still running, however, changes to the master are
not being received by our slaves.
We're running a farm of 4 slave mysql machines (MySQL version 3.23.41)
that talk to a single master (also version 3.23.41) machine. We're
running two databases on the machines (I'll call them db1 and db2), but
I only wish to replicate one of them (db2).
I've sync'd the databases, and turned on replication, and everything
works great until we load data into _db1_ via the 'load data infile'
command.
At that point, any further changes to db2 are not replicated to the
slave machines.
Running 'show processlist' at that point, on any of the slaves, gives
the following:
| 1294 | system user | none | NULL | Connect | 5233 | Reading master
update | NULL
Running 'show slave status' gives:
| master | user | 3306 | 60 | p23-bin.004 | 380 | Yes | db2 | db1
| 0 | | 0 |
Running 'show processlist' on the master reveals:
| 4 | repl | 10.1.1.108 | NULL | Binlog Dump | 2666 | Reading from net
| NULL
Running 'show master status' on the master gives:
| p23-bin.004 | 11283 | db2 | db1 |
If I run 'mysqlbinlog -j 380 p23-bin.004 |head' on master I get:
# at 380
#010830 15:39:21 server id 1 Query thread_id=32exec_time=0
error_code=0
use db1;
SET TIMESTAMP=999203961;replace into time_last_updated (time,table_name)
values ('2001-08-30 15:24:16','person_function');
If I issue 'slave stop' and 'slave start' on a slave, it syncs up to the
master, and will continue replicating until db1 is updated. Restarting
the master will also allow all of the slaves to sync up.
Here's the mysqld section of my.cnf from the master:
[mysqld]
#port= 3306
#socket = /tmp/mysql.sock
skip-locking
set-variable= key_buffer=384M
set-variable= max_allowed_packet=16M
set-variable= table_cache=512
set-variable= sort_buffer=6M
set-variable= record_buffer=1M
set-variable= myisam_sort_buffer_size=128M
set-variable= thread_cache_size=4
set-variable= thread_concurrency=4 # Try number of CPU's*2
set-variable= tmp_table_size=4M
set-variable= net_read_timeout=300
set-variable= net_write_timeout=300
# Uncomment the following if you are using BDB tables
#set-variable = bdb_cache_size=64M
# Point the following paths to different dedicated disks
#tmpdir = /tmp/
#log-update = /path-to-dedicated-directory/hostname
# Replication
log-bin
server-id=1
binlog-do-db=db2
binlog-ignore-db=db1
And from the slaves:
[mysqld]
#port= 3306
#socket = /tmp/mysql.sock
skip-locking
set-variable= key_buffer=384M
set-variable= max_allowed_packet=16M
set-variable= table_cache=512
set-variable= sort_buffer=5M
set-variable= record_buffer=1M
set-variable= myisam_sort_buffer_size=128M
set-variable= thread_cache_size=4
set-variable= thread_concurrency=4 # Try number of CPU's*2
set-variable= tmp_table_size=3M
set-variable= net_read_timeout=300
set-variable= net_write_timeout=300
set-variable= max_connections=500
log-update
# Replication
master-host=master
master-user=user
master-password=password
master-port=3306
server-id=3
replicate-do-db=db2
replicate-ignore-db=db1
log-slave-updates
#log-bin
If anyone could shed some light on this is happening, and more
importantly, how we can keep the replication going, or if you need any
other information, please let me know.
Thanks,
Jeff Adams
