ashok, from cusat
Sir,
I am facing problem in one function , actually in my table
there is two field: id, and password and I am checking the id
field for any user who is added to the friendlist of another user,
like in yahoo messenger.
MYSQL *conn;
MYSQL_RES *res_ptr;
MYSQL_ROW sqlrow;
FILE *fp;
/**/
int Friend_Result()
{
unsigned int i; int rows;
while( (sqlrow = mysql_fetch_row(res_ptr)) != NULL)
{
for(i = 0; i mysql_num_fields(res_ptr); i++)
{
if(i 0) printf(\t);
if(sqlrow[i] != NULL) printf(%s, sqlrow[i]);
else printf(%s, NULL);
}
printf(\n);
}
if(mysql_errno(conn) != 0)
{
printf(mysql_fetch_row error\n);
return 0;
}
if((unsigned long)mysql_num_rows(res_ptr) == 0)
{
printf(Invalid Not have a valid TARA ID...\n);
return 0;
}
return 1;
}
/**/
int Check_Exist_Friend(char *f)
{
char buf[200];
int result, rows;
printf( Friend = %s\n, f);
strcpy(buf, SELECT id from tara_user where id = );
strcat(buf, ');
strcat(buf, f);
strcat(buf, ');
result = mysql_query(conn, buf);
res_ptr = mysql_store_result(conn);
if(res_ptr == NULL) printf(Storing Error\n);
else
{
printf(Res_ptr is not null\n);
if(! Friend_Result() ) return 0;
mysql_free_result(res_ptr);
}
return 1;
}
/* CHECK THE FRIEND - ID IN DATABASE ***/
void Add_New_Friend(char *a, char *gp, char *f, int sd)
{
int result;
char buf[200];
printf(Friend name = %s\n, f);
if(! Check_Exist_Friend(f) ) return;
else
{
strcpy(buf, INSERT INTO flist values();
strcat(buf, ');
strcat(buf, a);
strcat(buf, ');
strcat(buf, ,);
strcat(buf, ');
strcat(buf, gp);
strcat(buf, ');
strcat(buf, ,);

strcat(buf, f);
strcat(buf,');

(unsigned long)mysql_affected_rows(conn));
else fprintf(stderr, Insert error %d: %s\n,

mysql_error(conn));
}
}
I am calling function Check_Exist_Friend(f) from
Add_New_Friend() but each time where the friend name is existing
in the table or not it give me the same result. I have tried a
lot but couldn't succeed.
I don't know where is fault , so please reply me . so that I
can do my rest of work.
If there are other option to check the existence of any user
whether the user is present or not , please let me know
Hoping positive response from your side.

Re: MySQL/InnoDB-4.0.7 is released
Hi! Buildmaster Lenz Grimmer of MySQL AB informed me that the last changeset in 4.0.7 was from Dec 20th, 2002. That means that InnoDB-4.0.7 is essentially the same as InnoDB-4.0.6, and the changes listed below will only appear in MySQL-4.0.8! I apologize for the confusion. It was my error not to check the exact date of the source tree snapshot in 4.0.7. Despite this confusion, I wish a prosperous New Year to all MySQL/InnoDB users! Heikki Tuuri Innobase Oy http://www.innodb.com - Original Message - From: Heikki Tuuri [EMAIL PROTECTED] Newsgroups: mailing.database.mysql Sent: Thursday, December 26, 2002 11:04 PM Subject: MySQL/InnoDB-4.0.7 is released Hi! InnoDB is a MySQL table type which offers transactions, row level locking, foreign key constraints, and a non-free hot backup tool. InnoDB is included in MySQL-Max-3.23 and all MySQL-4.0 downloads available at http://www.mysql.com. MySQL AB decided to release MySQL-4.0.7 just a week after 4.0.6 to fix a security issue in mysql_drop_db() in 4.0. InnoDB in 4.0.7 allows a user to define for a FOREIGN KEY constraints also ON UPDATE actions. This new feature has been requested by several users during the past year. As a special Christmas present you now have 4 % more free space in your tablespace to use for storage of tables and indexes. That is possible because the free space margin in InnoDB was reduced from 5 % to 1 % of the tablespace size. No conversion of tables is needed. You get the bonus space simply by upgrading to 4.0.7. Full changelog: * InnoDB now supports also the SQL syntax FOREIGN KEY (...) REFERENCES ...(...) [ON UPDATE CASCADE | ON UPDATE SET NULL | ON UPDATE RESTRICT | ON UPDATE NO ACTION]. * Tables and indexes now reserve 4 % less space in the tablespace. Also existing tables reserve less space. By upgrading to 4.0.7 you will see more free space in InnoDB free in SHOW TABLE STATUS. * Fixed bugs: updating the PRIMARY KEY of a row would generate a foreign key error on all FOREIGN KEYs which referenced secondary keys of the row to be updated. Also, if a referencing FOREIGN KEY constraint only referenced the first columns in an index, and there were more columns in that index, updating the additional columns generated a foreign key error. * Fixed a bug: if an index contains some column twice, and that column is updated, the table will become corrupt. From now on InnoDB prevents creation of such indexes. * Fixed a bug: removed superfluous error 149 and and 150 printouts from the .err log when a locking SELECT caused a deadlock or a lock wait timeout. I wish a prosperous New Year to all MySQL/InnoDB users!

Decimal and LOAD DATA
Hi all, I have a text-file containing products and their prices for a small shop. I upload and insert the text-file into a MySQL table using the LOAD DATA LOCAL INFILE command, and it really works a treat. My problem is that when inserting prices of more than one thousand, the field it gets inserted into formats it wrong. Ex: The field price is of type decimal(13,2), inserting via LOAD DATA etc. formats the price 1.139,00 to 1.13. I figured it had to do with different delimiters of thousands and hundreds (the text-file uses danish delimiters), so I cleaned up the file with PHP replacing the . with a , in prices above 1000, and vice versa. This doesn't seem to fix the problem though. I can tell that the replacing of ,'s and .'s is successfull (because I print the resulting output to the screen), but MySQL still interprets the number as 1.13, and not as 1.139,00 or 1,139.00 (yes, I tried both). Actually, I tried a plethora of formats including the following: 1139 113900 1.139,00 1,139.00 1139,00 1139.00 But MySQL interprets them all as 1.13. Inserting '1139' via CLI or phpMyAdmin works as expected, I get a price of '1139.00'. Is this an issue anybody dealt with before? I'd be happy to hear your findings on the matter. The code I wrote for importing the text-file can be found here: http://xslt.it-c.dk/~jcv/usenet/tusindfryd.phps The echo's are in danish, but you'll get the point of the script, hopefully.

The SQL determines distance between two zip codes: This is the Access original: SELECT Dealers.*, ((2285-Zips.North)^2+(4760-Zips.West)^2)^.5 AS Distance FROM Dealers INNER JOIN Zips ON Dealers.Zip = Zips.Zip ORDER BY (2285-Zips.North)^2+(4760-Zips.West)^2 The numbers in the calculations (such as the 2285 and 4760) are brought in from the Zips table prior to this piece of SQL being sent. I've tried a number of things (breaking it down into smaller chunks, changing ON to USING, etc.) but don't seem to be able to make the calculation work in the SQL. Any help here? Please reply to me since I only *subscribe* to the Win32 MySQL list. Thanks, John - John Asendorf - [EMAIL PROTECTED] Web Applications Developer http://www.lcounty.com - NEW FEATURES ADDED DAILY!

Based on that last statement, it sounds as though you're still loading the original file and not the transformed version. There is no way that MySQL will interpret *all* those values as 1.13. In any case, the values you end up loading should use '.' for the decimal point, and should not contain any commas at all. Ok, thanks. Inserting '1139' via CLI or phpMyAdmin works as expected, I get a price of '1139.00'. Is this an issue anybody dealt with before? I'd be happy to hear your findings on the matter. The code I wrote for importing the text-file can be found here: http://xslt.it-c.dk/~jcv/usenet/tusindfryd.phps Looks like you upload a file to $upload_file, transform its contents to $cleaned_file, and then attempt to use LOAD DATA with ... $upload_file! (rather than the transformed file). Blast, you are right! Well, sort of. I replace the content of $uploadfile with $cleaned_file here: # truncates the file pointer: ftruncate($fd,0); # writes content of $cleaned_file to file pointer $fd: fwrite($fd, $cleaned_file); But, I didn't put a + in my file pointer, so the file was only readable, not writeable, see? $fd = fopen ($uploadfile, r); Egad I feel stupid. Thanks for pointing me in the right direction, it works perfectly now. :) -- // Jonas C.

Re: birthday calculation problem
Hi,
I think you can try to use TO_DAYS() function;
eg:
select TO_DAYS('2002-12-28')-TO_DAYS(NOW());

Compare the MONTH() and DAYOFMONTH() values of your birthday column to the MONTH() and DAYOFMONTH() values for tomorrow's date, which you can calculate using CURDATE() and DATE_ADD().

RE: Trouble converting SQL from Access
OK, I've figured out how to fix the SQL (was searching for equations and calculations when I should have been looking for math in the docs!)... but now it takes EONS longer than the Jet calculations... SELECT Dealers.*, SQRT(POW((2285-Zips.North),2)+POW((4760-Zips.West),2)) AS Distance FROM Dealers INNER JOIN Zips ON Dealers.Zip = Zips.Zip ORDER BY POW((2285-Zips.North),2)+POW((4760-Zips.West)),2) Any suggestions to speed this guy up? There are 42,000 records in the Zips table and 4,000 in the Dealers table. The machine has a quad processor and runs the same query (below) in a second or two via access/ASP. With PHP/My it is taking 99% of the processor and doesn't finish. - John Asendorf - [EMAIL PROTECTED] Web Applications Developer http://www.lcounty.com - NEW FEATURES ADDED DAILY!

tailoring result display from multitable select
I'm trying to get results back from an sql query in the easiest way to handle in my script. table 'categories' and table 'restcat' (restaurant categories). I'd like to construct a query where I can look up a specific restaurant id, yet somehow related it to the categories table so that instead of a regular select/where, I get back something like: ++--+--+ | restaurant | category | category | ++--+--+ | 136| Chinese | NULL | | 136| French | NULL | | 136| Italian | Italian | | 136| Pizza| Pizza| | 136| Seafood | NULL | ++--+--+ Showing in this fashion that restaurant 136 is a member of the Italian and Pizza categories but not a member of the other categories. (and yes, my categories table actually uses category numbers) Thanx for any help! -- Andy - 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: Trouble converting SQL from Access
Well, I decided to stop being a moron and think inside the box and figured out that it was the total and utter lack of keys and indexes on the newly created MySQL tables which caused the execution time problem. So, the problem turned out to be, I'm a moron. Thanks everyone who replied! Here's the final query. It runs in about .3 second: SELECT Dealers.*, ROUND(SQRT(POW(2285-Zips.North,2)+POW(4760-Zips.West,2)),1) AS Distance FROM Dealers INNER JOIN Zips ON Dealers.Zip = Zips.Zip ORDER BY Distance -Original Message- From: Asendorf, John [mailto:[EMAIL PROTECTED]] Sent: Friday, December 27, 2002 1:12 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: Trouble converting SQL from Access OK, I've figured out how to fix the SQL (was searching for equations and calculations when I should have been looking for math in the docs!)... but now it takes EONS longer than the Jet calculations...

MySQL 4.0.7 is released
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, MySQL 4.0.7, a new version of the popular Open Source Database, has been released. It is now available in source and binary form for a number of platforms from our download pages at http://www.mysql.com/downloads/ and mirror sites. Around the time MySQL 4.0.6 was ready to be released to fix the security vulnerabilities that have been reported to us by eMatters GmbH, we were informed about another potential security vulnerability. Because the 4.0.6 builds were almost completed at this point, and we wanted to get these out to fix the already widely known security issues, we decided to resolve this vulnerability for MySQL 4.0.7 instead and release it immediately after MySQL 4.0.6. Users that use previous versions of MySQL 4.0 in an untrusted multi-user environment (e.g. ISPs providing database hosting) are encouraged to update to MySQL 4.0.7 as soon as possible. Please note, that this new vulnerability does only affect MySQL 4.0 - MySQL 3.23 is not affected by this bug. A short description of the vulnerability: o MySQL 4.0 did not properly check the user's privileges when receiving the (deprecated) client function call mysql_drop_db() to drop the specified database. o This allowed any user to arbitrary drop any database, if he was able to log in as a valid user and his MySQL client application used the obsolete mysql_drop_db() function call instead of the DROP DATABASE SQL statement. o When using DROP DATABASE, the user's privileges were always verified correctly before dropping the database. o This bug can not be exploited without a valid MySQL user account - it is not possible for an anonymous remote attacker to perform this operation. o So far, we are only aware of one client application that still uses this function call. o The mysql client application provided with the MySQL distribution as well as the MySQL Control Center cannot be used to exploit this vulnerability. o No data was compromised from other users' databases - this bug did not affect the privileges required to actually read data from other databases or tables. o If logging was enabled (e.g. by using the --log or --log-bin command line switches), the operation was also logged by the MySQL server, including the user and host name (if --log was used). We would like to thank Gary Huntress for making us aware of this problem. News from the MySQL 4.0.7 ChangeLog: Functionality added or changed: * `mysqlbug' now also reports the compiler version used for building the binaries (if the compiler supports the option `--version'). Bugs fixed: * Fixed compilation problems on OpenUnix and HPUX 10.20. * Fixed some optimisation problems when compiling MySQL with `-DBIG_TABLES' on a 32 bit system. * `mysql_drop_db()' didn't check permissions properly so anyone could drop another users database. `DROP DATABASE' is checked properly. Additional notes: * It is quite possible that not all mirror sites have picked up the Linux RPM packages yet, because the were added some time after the other binary packages. * Due to a hardware failure, we are currently unable to provide Solaris 2.7 binaries - we apologize for any inconveniences that may cause you. Some users reported, that the Solaris 2.8 package worked for them on Solaris 2.7, too - so you might want to give that a try. We are working on setting up a new Solaris 2.7 build system and hope to have it available for future releases again. Happy New Year!

RE: MySQL 4.0.7 is released
Hello, I'm a new user to MySql and I've just starting to download and install MySql. I've a question: Does each version of MySql has binary AND src version for installation ? I've been to http://www.mysql.com/downloads/ for MySQL 4.0.7 and I found binary version only. Does the majority of MySql user us the binary version ? Who would have the need to use src version of installation. I imagine that src version give user more options for customizing MySql. I'm installing MySql for use with vbulletin software from www.bulletin.com and I'm concerned whether I should install binary or src version of MySql. -Original Message- From: Lenz Grimmer [mailto:[EMAIL PROTECTED]] Sent: Friday, December 27, 2002 12:11 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: MySQL 4.0.7 is released -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, MySQL 4.0.7, a new version of the popular Open Source Database, has been released.

Quick from Commandline; very slow from Perl
Hey there,
Does anyone know why a query would take a very long time (15 minutes) from
my CGI script, yet takes less than a second if I cut-and-paste into my
console?
The query itself amounts to this:
SELECT ((a.PRECIP(0.00*AVG(b.PRECIP/100, a.DATE
FROM clim_data AS a
LEFT JOIN clim_data as b ON a.station=b.station and b.DATE=a.DATE - INTERVAL
30 DAY
WHERE a.station IN ('426409',
... long list of ID codes, about 500 of them ...
'WYTOR') AND a.DATE=20010101 AND a.DATE=20010102
GROUP BY DAYOFYEAR(a.DATE), a.station
...
1174 rows in set (0.53 sec)
My code is pretty simple:
-
$Result = RunQuery($q1$q2$q3);
my %attribs;
while(($value, $date)=$Result-fetchrow_array)
{
$attribs{$date} += $value;
}
$Result-finish;
--
sub RunQuery {
my ($query) = @_;
my $query_submittion = $database-prepare($query);
Debug(5, $query);
$query_submittion-execute() or Debug(1, $database-errstr, Query Error on
\$query\);
return $query_submittion;
}
--
But the server eventually will time-out. A query involving only one date
requires next to no time if I type it in manually, but 10 minutes from my
webpage.
Are there any variables I might have set wrong that would cause this to
happen? The MySQL server is on the same machine as the Apache one, and
there are a large number of rows being returned from this query. My first
thought is that the number of station ids being sent is what is taking so
long.
Any help is appreciated!
Thanks,
Nick Elliott

Desperate - failed: Lost connection to MySQL server during query
Hello All, This mail list is about my last hope as I tried everything I could possibly find online related to this problem and I've had no luck (it doesn't appear to be the GLib problem that everyone keeps talking about). Machine Specifics: Web Server (dedicated): P4 2gHz with 2gig memory RedHat 8.0 Apache 2.0 Perl 5.8 and latest DBI glibc-2.2.93-5 DB Server (dedicated): P4 2gHz with 2gig memory mySql 3.23.54 The problem is this, everytime the web server starts to work a little (load via a uptime showing about 6), 1 out of 5 scripts bomb out with the message of: failed: Lost connection to MySQL server during query As load gets higher then the rate of failure gets higher. There is NOTHING being reported by mysql on the DB server, even with warnings turned on - no DB restarts or nothing like that and at no time is load of any concern on the DB server nor do we have any problems with max_connections or anything of that nature. I have 3 other mysql boxes up and running (that work fine) and I went through all the default values given via the mysqladmin variables and everything is the same across multiple machines. I've found a ton of messages that show this same problem and they all relate to the RedHat version of Glib which is prior to mine. Also the reports I've seen all say this happens 100% of the time and in my case it only happens when load is high. Finally the reports say it causes mysqld to crash and restart which isn't happening (mysql isn't complaining about a thing). Does anyone out there have any idea? I'm at a total loss, everything is fine until load gets up there a little (and what little there is isn't overloading anything).

Do you mean that you want a starting value of 1000, and for subsequent records to auto_increment by 1000 each time? If so, you cannot ask MySQL to do that automatically. Or do you mean that you want the normal increment-by-one behavior, but you just want the first value to be 1000? If so, use a MyISAM table, and declare it as follows: CREATE TABLE tbl_name (column definitions here) TYPE = MyISAM AUTO_INCREMENT = 1000; The final AUTO_INCREMENT = n clause causes the first record to be assigned that value in the AUTO_INCREMENT column.

Bug report: UNIQUE KEY and DESCRIBE TABLE

Machine specs:
--
Compaq Presario desktop
512 MB RAM
Windows XP Professional SP1
Problem description:
MySQL does not return key information about any column after the first
in a unique multi-column key. Also, the MUL flag seems to indicate
that the key is non-unique, when in fact it is.
There is an equivalent symptom in the MySQL C API. In the flags field
of the MYSQL_FIELD structure returned by mysql_fetch_field(), the
MULTIPLE_KEY_FLAG will only be present in the first column.

style question: drop database in an install script
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, all -- I'm working up the schema for my application and, as you can imagine, starting over and reloading numerous times :-) In fact, I intend for the script to be an install script, run on a new installation of the software to set things up. The script starts out drop database if exist dbname ; create database dbname ; use dbname ; create table tablename ( ... ) ; ... to set things up and then continues insert into tablename (field,field,field) ( data , data , data ) , ... ( data , data , data ) ; ... to set up the predefined things (credit card types and so on). To reload the database and try something new, all I have to do is mysql -udroot -p script.sql and what was there goes away and is rebuilt fresh. That's mighty convenient as I'm building up a table's design and trying it out. Soo... When you experienced folks write software that's meant to be installed from a script or such, do you lead off with a 'drop database' command, or is that just too dangerous to put in a script and you make your users clean up any old installation by hand? This will have to be run by a root user, so we can figure that this user might have read the docs and know that he's going to start [over] from scratch, but then, again, users are users :-) Meanwhile, is there if/then/else functionailty in SQL so that I can say if exist dbname exit some error ; create database dbname ; ... and not try to create and populate a database on top of an existing one? Or is there perhaps a RENAME DATABASE command (I saw RENAME TABLE) so that I could rename the old one to get it out of the way but not toss it?

I've tried: 1. Going over the java.sql metadata functionality to see if I can query this through the standard java.sql functions. 2. Searching the MySql manual Any help much appreciated.

Re: Bug report: UNIQUE KEY and DESCRIBE TABLE

Also, the MUL flag seems to indicate that the key is non-unique, when in fact it is. 1) Use SHOW KEYS if you want better information about the indexes on a table. DESCRIBE (aka SHOW COLUMNS) reports some information about indexes, but that is not its primary purpose. 2) UNIQUE indexes can in fact hold non-unique values if any of the indexed columns can be NULL. (A UNIQUE index is allowed to store multiple NULL values.) But you are correct that the index in your particular table can *not* be non-unique, because neither of the indexed columns can be NULL. (A further manifestation of this problem is that UNIQUE indexes in BDB tables can *never* be non-unique, because BDB allows only one NULL in a UNIQUE index, in contrast to other table types.) There is an equivalent symptom in the MySQL C API. In the flags field of the MYSQL_FIELD structure returned by mysql_fetch_field(), the MULTIPLE_KEY_FLAG will only be present in the first column. - Test script: - mysqlUSE test mysqlCREATE TABLE mytable (a INT NOT NULL, b INT NOT NULL, c INT NOT NULL, d INT NOT NULL, PRIMARY KEY (a), UNIQUE KEY (b, c)); mysqlDESCRIBE TABLE mytable; -- Results: -- +---+-+--+-+-+---+ | Field | Type| Null | Key | Default | Extra | +---+-+--+-+-+---+ | a | int(11) | | PRI | 0 | | | b | int(11) | | MUL | 0 | | | c | int(11) | | | 0 | | | d | int(11) | | | 0 | | +---+-+--+-+-+---+ - 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?

unable to create File DSN
Hello all, Why can I not create a File DSN using MyODBC 2.50.39 on Windows 2000? I have installed MySQL v3.23.52-max-nt and MyODBC 2.50.39 on a Windows 2000 machine. While I can create both System and User DSNs, I cannot create a File DSN. When I try I get the error message File Data Source was not saved. I've checked the FAQ: http://www.mysql.com/products/myodbc/faq_3.html#DSN_Types but haven't found anything related to this. I'll keep searching other sources. But if anyone can point me in the right direction, I'd be thankful.
