RE: Advice wanted on Data Structure
-Original Message- From: Donald Tyler [mailto:[EMAIL PROTECTED] Sent: 30 July 2003 16:42 To: [EMAIL PROTECTED] Subject: Advice wanted on Data Structure I have a question that I hope I can explain well enough: I am trying to figure out a data structure for an inventory system. The system contains: Items Kits(Made from a collection of Items and/or other Kits) Now my question is: Is there any way to structure this in a database so that I could run a single query to get the contents of a kit, even though it contains other kits? My problems occur when I try to create the tables as so: ITEMS:KIT_CONTENTSKITS KIT_IDKIT_ID ITEM_ID-ITEM_ID Description Description Price Etc This is a classic problem known as a Bill of Materials explosion and unfortunately relational databases don't handle it very well. Storage is easy(ish). Fundamentally you have a recursive many to many relationship between components, resolved as Component: Component_Link id ---|---assembly_id name|---subcomponent_id That is 2 foreign keys back to the same master table, if the diagram isn't clear. In OO terms, both item and kit are subclasses of component. There are may ways to implement that in a relation database, but the simplest is to store them as a single table with a type field. Retrieval is harder. To get the contents of an assembly (kit), select * from component as assembly, component as subcomponent, component_link where assembly.name=? and component_link.assembly_id=assembly_id and subcomponent.id= componentLink.subcomponent_id BUT, this only goes down to one level which may be enough for most purposes, but for stock monitoring (e.g. I've sold 10 of kit ZZA102, what effect does that have on my item stocks), you need to do it recursively. With mysql ( and most other DBMS) the only alternative is to do the recursion in a program - ie get all first level children foreach get next level foreach get next level etc Oracle has an excellent CONNECT BY extension to standard sql which does this brilliantly, and I believe mysql AB are planning to imlpement it sometime. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Transactions
I'm reticent to consume any more of this lists bandwidth and trust this will end the thread, but here is my point. There are many 'gotchas' to consider when developing an application that uses any dynamic file structure from simple flat ascii files to engorged dbms's. Add multi-user and multi-tasking to the mix and you have a tiger by the tail. The bottom line is, it is the responsibility of the programmer to ensure that every tool they use is safely and correctly implemented. Transactions or commit and rollback levels help, but they are only a small piece of the package. It is dangerous to assume that because referential integrity has been maintained, that the data is as intended. Any application that allows its data to be manipulated in other than a read-only status is responsible for its integrity. Forgive me if I'm missing the point here I have only just finished a database programming course in university and do not have extensive real practice. However I was tought that databases are responsible (among other things) of data integrity and consistency. Yhe client's job is to add data and ask for data. The rest should be database's job. Database ensures there are no violation of business rules (constraints, foreign keys) and that full data not just part of it will be added (transactions). Of course a client must be programmed in a way to make use of these features. But all the things you were talking about really are part of RDBMS definition. appropriate result to the client. You certainly would not want to lock a region or even a row from a stateless client. If two people access the same record/row at the same time and change non-key information but commit the changes sequentially 2 seconds apart the referential integrity could be correct, but the data is not as the first person intended. In this scenario, the programmer needs to provide a mechanism to advise the first client that his changes were overwritten, thereby turning a stateless event into a stateful one and maintaining control of the application. This situation is one of the main reasons you want to use a database. It is database's job to handle multiple simultaneous accesses on the same data/row. This is not an easy task, there are several different locking mechanisms to implement this and different types of transactions for end users/client applications. Database creators have spent a lot of time on implementing these things so it is probably quite wise not to try to invent a bicycle here. A robust file handler or dbms is a wonderful tool but it is only a tool and does not relieve a programmer of their responsibility. That's my point. It is not the APPLICATION programmers responsibility to handle simultaneous accesses to the same data, to ensure data integrity. The application/database user only sends data to database and asks for data. The rest is the job of RDBMS. Thats the whole point of using a RDBMS imho.

help to structure query without using subselects
Hi List Can anyone help me to do the following without the need of subselects: I have a table that contains rows where mostly, the only common field is the name. The rest of the data fields, even though they are related to the name, differs from row to row ( they are things like the address etc, which could have changed on the next entry for the same name) What I'm trying to get out of the table is a list of all the names ( with the duplicates pruned out by DISTINCT) and other collumns for the row with the highest id. This works: select distinct name, max(id) as mid from table group by name but it only returns the name and the highest id for such a name. if I try this: select distinct name, max(id) as mid, anything_else from table group by name it returns the FIRST anything_else, and not the value in the last row for that name ( as I would like it to) Any help? mysql, query -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Deleting Duplicate Records
The cleanest way is to add a column (ukey) to the table which will uniquely identify each record. This will help you in the following phases too. Let's say the name of your table is 'focus_table'. 1.adding the unique key 'ukey': ALTER TABLE 'focus_table' ADD COLUMN ukey BIGINT(12) AUTO_INCREMENT PRIMARY KEY; *Now you know what records are remaining after deleting the duplicates and the table will have the same structure. 2.backup your table 3.select the duplicates: CREATE TEMPORARY TABLE dupls SELECT * FROM 'focus_table' GROUP BY field1,field2,... ; *field1,field2,... is the list of the fields which give the duplicates. 4.empty the table: DELETE FROM 'focus_table'; 5.fill it with unique records: INSERT INTO 'focus_table' SELECT * FROM dupls; - Original Message - From: Cybot [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, July 31, 2003 11:41 AM Subject: Re: Deleting Duplicate Records Kim Mackey wrote: Group, I have been working on a project for a while now trying to figure out how to remove duplicate records from a single table using a query.

Help!!! Need to backup mysql using - MYSQL Second Edition?
Hello again, Still a newbie, and running mysql on windows 2000 Advanced Server. I am trying to backup mysql and was confused as to which command to use. I see the following options mysqldump mysqlhotcopy Now the confusion is really in the syntax used in the MYSQL Second Edition. I looked on page 718 and I am thinking that the command is for a Unix system. Since I am running on Windows, do I need to first create the directory where I want mysql to be backed up? And secondly, it is recommended that I do not backup in the same volume, so what exactly is the command for me to use, if mysql resides on C:\ and I want to back it up in the D:\? I should tell you that my PC is still a standalone, and I am planning to take it online soon. So the backup is a local backup. Thank you all in advance

RE: Finding Table and database size
Hello Dan, Probably the reason that no-one has replied to you is that on-one feels that they have anything helpful to add to what you already know. A quick check on my system shows that the data and index sizes reported by SHOW TABLE STATUS are the same as the byte sizes of the MYD and MYI files - which is a clue that they may represent the table sizes in bytes. Whether this also applies to InnoDB tables, I have no idea. SImply checking the manual page http://www.mysql.com/doc/en/SHOW_TABLE_STATUS.html will show that there is no syntax for selecting only a few columns from the SHOW STATUS. The fact that no-one else has replied suggests that there is no alternative command. However, unless your number of tables is prodigious, the extra data transferred is hardly likely to be prodigious. If you phrase your question in the style please tell me more, then you must accept that silence means that there is no more to tell. If this list cannot answer your question, your only alternative is to purchase support from MySQL AB (always a good idea) , and then enquire of the fount of all (MySQL) knowledge.

Re: Deleting Duplicate Records

RE: Finding Table and database size
Hello Dan, Probably the reason that no-one has replied to you is that on-one feels that they have anything helpful to add to what you already know. A quick check on my system shows that the data and index sizes reported by SHOW TABLE STATUS are the same as the byte sizes of the MYD and MYI files - which is a clue that they may represent the table sizes in bytes. Whether this also applies to InnoDB tables, I have no idea. Excellent SImply checking the manual page http://www.mysql.com/doc/en/SHOW_TABLE_STATUS.html will show that there is no syntax for selecting only a few columns from the SHOW STATUS. The fact that no-one else has replied suggests that there is no alternative command. However, unless your number of tables is prodigious, the extra data transferred is hardly likely to be prodigious. I figured that, I'll just have to loop around in my function and add it all up. If you phrase your question in the style please tell me more, then you must accept that silence means that there is no more to tell. If this list cannot answer your question, your only alternative is to purchase support from MySQL AB (always a good idea) , and then enquire of the fount of all (MySQL) knowledge.

mysql_history file?
We're just getting started with MySQL on Linux; I was browsing my home directory and found a file called .mysql_history. It contains a history of all mysql commands I've entered - including logging on, setting passwords for users, etc. Sure enough, other users of mysql have the same file. Questions: What are these files, are they mandatory, or can I turn off this logging? Do we need to keep an eye on growth of this files, and truncate or archive them?

Mysqlcc vs Phpmyadmin
Hello again people, Can someone tell me if mysqlcc does the same thing as phpmyadmin. Thank you all Ola
Re: max clients
The answer (like most of these) is, it depends. You really need to benchmark your application to know how often a user is going to actually hit your database server, and how many connections the application creates for each user. I've got a server that handles the databases for 3000 users hitting web apps on several different web servers without blinking (dual P4 Xeon, 2 GB of memory). It runs at worst 75% idle. On the other hand I've seen applications where 100 users would bring this server to it's knees if it were serving the database for it. It all depends on usage and you can't get from users to database usage directly. I would pile up some hardware your not using at the moment set things up and write some scripts to simulate actual usage of your application. Load the server with some real data, especially in terms of quantity of rows, and see what it handles. Measure performance and system usage metrics and go from there. -- Michael Conlen NEWMEDIAPLAN wrote: Can mysql handle 5000 concurrent webusers sending queries to the db through a web search engine.

ARGGH! - User password problems
All,
I've been attempting to assign a password to a user with the following
statement:
UPDATE mysql.user SET password=PASSWORD('foo') WHERE user = 'acc_name';
I get the typical:
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
However, when the user attempts the login using the password they are
unable (access is denied to acc_name with password yes). If they
attempt to login without a password, they are successful - WTF!.
There is only 1-entry in the user table for this user so I didn't
specify a host.
Next, for the same user account, if I try to login from a remote
machine (via ODBC) I am denied access (event with the blank password!).
The user has the following host '%' (no other hosts present), yet I
receive an error that reads:
Access denied for user: '[EMAIL PROTECTED]' (Using password: NO)
HELP before I lose my mind and start pretending I am a glass of orange
juice.

Adam

study on composite keys and different column types
From going over http://www.mysql.com/doc/en/MySQL_indexes.html (again) http://www.mysql.com/doc/en/Indexes.html (again) And doing some experimentation it seems that when I build a compound index (A key spanning multiple column) of column types String, int, int - sorting the result takes a very long time when compared to int, int, String - type keys Even though there are more distinct values of strings then ints: and it would make sense to have String 1st as the leftmost prefix to avoid yet another standalone index (since it's required for lookup) the results where an order of magnitude faster.

Backup conventions
Hi, I'm a new user of MySQL on Linux. I have been an Oracle DBA; and know that anyone familiar with Oracle takes backup procedures very seriously Anyone have recommendations for nightly backup procedures for MySQL (transactional) databases? The literature seems a little ambiguous on this. I did 'turn on' the general, binary and error logs. Does anyone shut down the MySQL daemon regularly? Anyone use mysqldump, or do folks simply use a file system backup? We have tons of databases and tons of tables, so I'm not really considering the lock/flush procedure on tables...

connections aren't released?
Hello,
I am having some performance difficulties due to the number of
connections getting so high. I know that the correct way to solve this
is by using connection pooling, but for now I can't figure out why the
connections are'nt being released as I expect.
I am using Tomcat 4.0, with mm.mysql-2.0.14-bin.jar on Linux 7.2 to
connect to a MySQL max 3.23.51 database. I open the connections in a
bean with:
private void connect () {
String url=jdbc:mysql://mysqlserver/database;
String username=someusername;
String password=somepassword;
String driver=org.gjt.mm.mysql.Driver;
try {
// load db driver
Class.forName (driver);
// establish net connection to db
this.connection=DriverManager.getConnection (url, username,
password);
} catch (ClassNotFoundException cnfe) {
System.err.println (Error loading driver: + cnfe);
} catch (SQLException sqle) {
System.err.println (Error connection: + sqle);
}
}
public Connection getConnection () {
if (this.connection==null) {
this.connect ();
}
return this.connection;
}
and I close the statements, resultsets and connections with
statement.close();
rs.close();
and connection.close;
But when I track Threads_connected with show status, I see that the
connections aren't released until the session is terminated with
session.invalidate();
Any insights?
Thanks,
Bill

Help Please: Substitute Text to replace Stored Procedures for use with MySQL
Hi I have purchased a package that uses ASP and SQL, my webhost provides MYSQL and I have loaded my access database and all seems to be working fine. Except the stored procedures (Queries) the webhost says MYSQL doesn't support stored procedures, as this site confirms (wait for v5.0) but the same effect can be achieved using ASP, an example of what they offer in help is below: SQLQuery = SELECT * FROM tblAPCategories Set RS = gsconnect.Execute(SQLQuery) Do While Not RS.EOF % %=RS(catID)%, etc... This works fine for dumping the contents of these fields to the screen, my problem is that my ASP app calls stored procedures in the following way: sSQL = qdpAPGetMaxCatLevel etc... the variable seems to be called repeatedly after this, I'm assuming sSQL is the variable, the query for this is: SELECT Max(catLevel) AS calcMaxLevel FROM tblAPCategories; The answer is 3 which I can get to using the ASP text suggested, but I can't seem to work out how to replace the call to the stored procedure with the ASP text to make the ASP function as intended, it just crashes out at the point this is called, and believe me I have tried everything, except what works obviously. I even tried creating a table with the same name and typing in the answer just to see if I could further, it knew it was a table and stopped just the same. Can anyone help, if I can crack one I think I can crack the rest, although to be fair this appears to be one of the easier queries. Thanks in advance for anyone's help. Chris
Re: mysql and Access
The simplest way, if you have the ability to make an ODBC connection to the mySQL box, would be to create an ODBC linked table in access and then run an append or make-table query against the linked table, as per your situation requires. I assume that you could write a macro that would run the query on a daily or hourly basis or something. If you're not able to create an ODBC link to the mySQL database, then there will most likely be some manual intervention. It would not be hard to procedure-ize and mostly automate the export and import process, though (with a little help from their ISP). (I'm assuming that they have an ISP that is hosting the box, if they're not hosting the box locally. If they were hosting it locally, they'd most likely be able to create an ODBC connection to it.) So the short answer is: Yes, you can, but if you have to ask, (or if most of what I've written so far went over your head), you'll probably want to get some help doing it. -Cameron Wilhelm On Thursday, July 31, 2003, at 04:41 PM, Voodoo wrote: I'm building an integrated system with Access and mySQL.

FULLTEXT Searching
I have to do a catalog search through multiple tables and columns for
product model number, description, and name. I realize that doing
pattern matching with multiple LIKE statements is slow so I found that
FULLTEXT searches is a better alternative.
I have added a FULLTEXT index to the tables I'm searching, but I get an
unkown error when I run my query:
SELECT p2c.categories_id, p.products_id, pd.products_name,

p.products_price, p.products_date_added, p.products_last_modified,
p.products_date_available, p.products_status
FROM products p, products_description pd, products_to_categories p2c
WHERE MATCH(p.products_model,pd.products_name,pd.products_description)
AGAINST('pumps')
AND p.products_id = pd.products_id
AND p.products_id = p2c.products_id
ORDER BY pd.products_name;
This is how my table structures look:
CREATE TABLE `products` (
`products_id` int(11) NOT NULL auto_increment,
`products_quantity` int(4) NOT NULL default '0',
`products_model` varchar(12) default NULL,

I did check to see if mysqld was running, but of course it wasn't. I
also tried the perl script run-all-tests, but it just reported mysql
wasn't running ('Can't connect to local MySQL server through socket
'/var/lib/mysql/mysql.sock' (2)' when connecting to
DBI:mysql:database=test;host=test;host=localhost with user: ''
password:
'')
Can anyone help?
Thanks

Re: Books advice
Hi I guess I will plug Paul's books. I have his MySQL book and his MySQL and Perl for the Web. I really enjoyed the second one but the MySQL book was very well written. I also have read Sam's teach yourself MySQL in 21 days which seemed pretty light weight and I never look up anything in it. I also have the MySQL reference manual which is great for really technical type questions.

Re: help to structure query without using subselects
* Petre Agenbag [...] This works: select distinct name, max(id) as mid from table group by name but it only returns the name and the highest id for such a name. if I try this: select distinct name, max(id) as mid, anything_else from table group by name it returns the FIRST anything_else, and not the value in the last row for that name ( as I would like it to) Try the MAX-CONCAT trick: select distinct name, max(concat(id,'|',anything_else,'|',even_more)) as name_info from table group by name Then you must programatically split the 'name_info' column back to the individual fields, or use SUBSTRING, like in the example in the manual: URL: http://www.mysql.com/doc/en/example-Maximum-column-group-row.html HTH, -- Roger -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Impossible mysqldump - Please HELP!!!
I am running mysql 4.0.13 on Apache 2.0.47 and PHP 4.3.2. I can log onto my Mysql and I can show databases, and create users and passwords. OS is Windows 2000 Advanced Server. In trying to backup my database, I used the MySQL Second edition syntax and also used something somebody suggested in a previous email, unfortunately I got error code 1064 in both cases. I tried the following: Name of database in this case is candleplace and I got this syntax from MYSQL 2nd Edition. mysql mysqldump --opt candleplace /archive/mysql/candleplace.073103 What I got was: ERROR 1064: You have an error in your SQL syntax.

Greetings I have MySQL 4.0.14 running on WinXP. Whenever I create a temporary table from an existing table that has multiple keys ( the temporary table has columns reordered from the original table ) with a query like - create temporary table if not exists `mn`.`sqlyog_23796` ( `entryid` int(6) unsigned NOT NULL auto_increment , `caseid` int(6) unsigned NOT NULL DEFAULT '0' , `litigantid` int(6) unsigned NULL , `litiganttype` char(1) NULL , `counselid` int(6) unsigned NULL , primary key ( entryid ) ,KEY `caseid` ( `caseid` ), FULLTEXT KEY `counselid` ( `counselid` ), FULLTEXT KEY `litigantid` ( `litigantid` )); I get a error - Error No. 1005 Can't creat table 'C:\WINDOWS\TEMP\#sql794_37_2.frm' (errno: 140) Why the above query is not working?
