Full Text Index and MySQL 4.0.2
Now that MySQL 4.0.2 has been released, does anyone know if Support for always-index words is available? This is mentioned in the todo: http://www.mysql.com/doc/F/u/Fulltext_TODO.html 'Support for always-index words. They could be any strings the user wants to treat as words, examples are C++, AS/400, TCP/IP, etc.' If this feature is supported, I would appreciate any help in getting this to work.

RE: C API: mysql_data_seek
Hi,
Thanks for ur reply.
When i commented out the mysql_data_seek() function, mysql_fetch_row()
returns me a non-NULL value (this should be the first row from the MResult).
This results show that I've a valid connection and/or query. And when I
call mysql_fetch_row() again (retrieving the 2nd row from the MResult,
which is the desired row), it returns me a non-NULL value too. From this
result, I know that I've not seek past the result set. However, with the
addition of the mysql_data_seek(MResult, 1) function, a NULL value is
returned. And that's where I don't know how the mistake was made.
Please advice and thanks.

Warning message with MySQL++ API
Hello, I just start trying building a program in C++ using MySQL++ API. I want to use sql_create_basic_n macros to manage results of queries on my database. So I defined structures using this macro based on the tables of the db. for example, in the db I have a table defined as follow: +---+--+--+-+-++| Field | Type | Null | Key | Default | Extra |+---+--+--+-+-++| || ID | int(10) unsigned | | PRI | NULL | auto_increment || name | varchar(60)| | | | || op | blob | YES | | NULL| || date| datetime| | | -00-00 00:00:00 | |+---+--+--+-+-++ and I defined a structure for this table as follow : sql_create_basic_4(structclass, 0,0, unsigned int, id, string, name, string, op, Date, sdate) The problem is when I compiled, I get a lost of warning for each of the defined structures: CGtad.h:10:1: warning: pasting - and id does not give a valid preprocessing token CGtad.h:10:1: warning: pasting - and name does not give a valid preprocessing token CGtad.h:10:1: warning: pasting - and op does not give a valid preprocessing token CGtad.h:10:1: warning: pasting - and sdate does not give a valid preprocessing token CGtad.h:10:1: warning: pasting structclass and :: does not give a valid preprocessing token CGtad.h:10:1: warning: pasting :: and structclass does not give a valid preprocessing token CGtad.h:10:1: warning: pasting populate_structclass and does not give a valid preprocessing token CGtad.h:10:1: warning: pasting sql_COMPARE__0 and ( does not give a valid preprocessing token etc Does anyboby have an idear of how to resolve this ? -- Cordialement.

Re: C API: mysql_data_seek
Hi,
If i understand well you use twice mysql_data_seek.If you use
mysql_data_seek() after mysql_fetch_row() the effect is NULL.
Because mysql_data_seek() (in fact) set the cursor (if we can said like
this...) in the MResult (MYSQL_RES) and not in the row (MYSQL_ROW).

RE: Implementing commit,transaction in isam table type
Seems fairly impossible to me to really emulate transactions on a non-transactional db. Even if you develop a system where you : a. collect all queries untill the end and then perform them in 1 block b. keep your own logs of the queries and be able to roll them back in case of error even then it will not be a real transaction, because for example : - a server-crash whilest doing the 1-block-query will corrupt the database - same for the roll back you have written - you don't have isolation levels, so queries will read wrong data - ...

Bug with AUTO_INCREMENT
Hi,
Continuing my troubles with AUTO_INCREMENT (which nobody has yet
responded to), I've now ruled the Perl DBI out of the equation and
reproduced the same problem using the mysql.exe command-line tool.
Hopefully somebody will be tempted to help this time now that there is
no Perl involved to put people off?
The bug can be reproduced as follows:
Create the following simple database containing just one BDB table:
CREATE DATABASE test;
CREATE TABLE foo (
id INT NOT NULL AUTO_INCREMENT,
num INT,
str VARCHAR(10),
PRIMARY KEY (id)
) TYPE=BDB;
Now start two mysql.exe sessions running with the -f flag to ignore
errors.
Set each one into no auto-commit mode with:
SET AUTOCOMMIT=0;
and then feed each of them the following two lines 50,000 times each:
INSERT INTO foo (num, str) VALUES (1, 'a');
COMMIT;
On my NT4 machine I do this with the simple Perl program (I know I said
Perl wasn't involved, but the Perl DBI still isn't):
sql.pl
--
print SET AUTOCOMMIT=0;\n;
for (1 .. 5) {
print INSERT INTO foo (num, str) VALUES (1, 'a');\n;
print COMMIT;\n;
}
I pipe the output from this to the mysql.exe programs, and then
re-direct STDERR from that to log files, e.g.:
Command Prompt One:
\perl5\bin\perl.exe sql.pl | \mysql\bin\mysql.exe -f -u root test 2
session1.txt
Command Prompt Two:
\perl5\bin\perl.exe sql.pl | \mysql\bin\mysql.exe -f -u root test 2
session2.txt
When I inspect the output collected in these log files I find, not
unexpectedly, that there are many deadlock errors (which I'm quite
comfortable with, and can handle in my real software by simply retrying
the transaction), but that there are also a few of the following error:
Duplicate entry '1' for key 1
Surely this is a bug isn't it?
The transaction that is being performed 50,000 times each by the two
mysql.exe sessions doesn't specify any value for the AUTO_INCREMENT
column id - it just leaves it up to the database to choose the next
value.
This error suggests that the database has wrongly chosen the value '1',
and then (rightly) complains that it is already used!
I would really appreciate a response on this one as I'm now at the end
of my tether trying to work out what is wrong.
Thanks in advance,
Steve

RE: C API: mysql_data_seek
Hi Gelu,
Thnx for the prompt reply.
I called mysql_data_seek() once and I called it before mysql_fetch_row().
With this, mysql_fetch_row() returns NULL row.
Then I decided to check if the connection (and query) is valid by commented
out mysql_data_seek(). I called only mysql_fetch_row() and it returns
non-NULL row. From the result, I know that the connection and the query
are valid.
The next thing I check is the number of rows in the MResult. I have 3 rows
altogether. Hence, it should return me something if I set the cursor (using
mysql_seek_data() ) to the 2nd row and then get the row with
mysql_fetch_row(). However, this does not work.
I've checked my concept on mysql_data_seek() against the description you
have provided in the first reply, and I do not detect any different. Hence I
presume the mistake was made due to some special considerations which I do
not know. Please advice.
Once again, thnx for replying.
Regards,
wv

Subject: C API: mysql_data_seek
Hi,
I'm using the MySQL built-in C function, mysql_data_seek, for accessing
a
particular row from the Result (MYSQL_RES) returned by
mysql_store_result.
int sql_result;
MYSQL_RES *MResult;
MYSQL_ROW row;
MYSQL MQuery;
char SQLQuery[];
sprintf( SQLQuery, SELECT * FROM Profile );
sql_result = mysql_query(SQLQuery);
MResult = mysql_store_result(MQuery);
mysql_data_seek(MResult, 1);
row = mysql_fetch_row(MResult);
However, row returns NULL. I wonder if I've made any mistake in the
process. Can someone please help to check? In addition, is there any
special considerations when using this function?
Thanks in advance.

Yes, I realise that, but I'm not INSERTing '1' into a UNIQUE field.
The '1' in the code below is INSERTed into the 'num' column, which, if
you look at the database definition, is not specified as UNIQUE.
The error that I'm getting refers to key 1, which is the 'id' column.
You'll note that I'm not specifying a value for the 'id' column - I
leave it up to the database to choose a value itself (it is an
AUTO_INCREMENT column) and it keeps wrongly choosing a value that is
already used.
I'd say that IS a bug.

Re: SQL select rows conditional on same select
Thanks Chuck! The last example you gave looked just right, but when I ran it, it returned an error. A quick look at the mysql manual revealed that UNION SELECTs are on the TO DO list for mysql :( With the examples you provided though, I was able to create the following statement which returns exactly what I wanted. select distinct X.id, X.title from X, Y where X.id=Z or (X.id=Y.assoc and Y.id=Z); when Z = 1 ++---+ | id | title | ++---+ | 1 | one | | 3 | three | ++---+ when Z = 2 ++---+ | id | title | ++---+ | 2 | two | | 3 | three | | 4 | four | ++---+ and when Z = 3 or 4 or 5, it just returns the single row that I would expect. Again, thanks. Carl Carl Franks wrote: Hi, I have 2 tables, X and Y. table X table Y ++---+ ++---+ | id | title | | id | assoc | ++---+ ++---+ | 1 | one | | 1 | 3 | | 2 | two | | 2 | 3 | | 3 | three | | 2 | 4 | | 4 | four | ++---+ | 5 | five | ++---+ I wish to retrieve the X.id and X.title where X.id=Z select X.id, X.title from X where X.id = Z and also the X.id and X.title where (X.id=Y.assoc) when (Y.id=X.id) select X.id, X.title from X, Y where X.id = Y.assoc and X.id = Y.id So... I think you want the OR of those two statements. The obvious way to do this might be: select X.id, X.title from X where X.id = Z union select X.id, X.title from X, Y where X.id = Y.assoc and X.id = Y.id or: select X.id, X.title from X, Y where ( X.id = Z and not exists (select * from X, Y where X.id = Y.assoc and X.id = Y.id) or X.id = Y.assoc and X.id = Y.id) The above won't work in current versions of mysql, and probably can't make very good use of indices. It can be simulated in mysql via: select distinct X.id, X.title from X, Y where ( X.id = Z or X.id = Y.assoc and X.id = Y.id) but I'm trouble trying to express this as a single SQL statement. Could someone help me out with this, or at least give me a clue as to how to think this one through? In case I haven't explained it very well, I'll describe exactly what I'm doing. Z is a product number, and I want to retrieve the (table X) data for product Z and also the (table X) data for any other products associated with it, represented by table Y. The above paragraph seems different than what you said above. To get the data for products associated with product Z, I think you want Y.id = Z and X.id = Y.assoc select X.id, X.title from X where X.id = Z union select X.id, X.title from X, Y where X.id = Y.assoc and Y.id = Z Chuck I know I could do it using 2 select statements, firstly just selecting X.id, X.title, Y.id, Y.assoc where X.id=Z (I'm using perl DBI) and then within the perl program create another SQL statement selecting X.id, X.title WHERE Y.assoc IS NOT NULL in the results from the first select. However, I would like to do this with one SELECT if it's possible, for efficiency.

If i understand well, mysql_fetch_row() work fine but if you add
mysql_data_seek() the row is NULL.
...you use pointers when declare variables ?In my pre-previuos e-mail i fill
what (i considered) it's not was OK.
MYSQL_RES *MResult;
MYSQL_ROW *row;

Hi Gelu,
Thnx for the prompt reply.
I called mysql_data_seek() once and I called it before mysql_fetch_row().
With this, mysql_fetch_row() returns NULL row.
Then I decided to check if the connection (and query) is valid by
commented
out mysql_data_seek(). I called only mysql_fetch_row() and it returns
non-NULL row. From the result, I know that the connection and the query
are valid.
The next thing I check is the number of rows in the MResult. I have 3
rows
altogether. Hence, it should return me something if I set the cursor
(using
mysql_seek_data() ) to the 2nd row and then get the row with
mysql_fetch_row(). However, this does not work.
I've checked my concept on mysql_data_seek() against the description you
have provided in the first reply, and I do not detect any different. Hence
I
presume the mistake was made due to some special considerations which I do
not know. Please advice.
Once again, thnx for replying.

Hi,
If i understand well you use twice mysql_data_seek.If you use
mysql_data_seek() after mysql_fetch_row() the effect is NULL.
Because mysql_data_seek() (in fact) set the cursor (if we can said like
this...) in the MResult (MYSQL_RES) and not in the row (MYSQL_ROW).

Thanks for ur reply.
When i commented out the mysql_data_seek() function,
mysql_fetch_row()
returns me a non-NULL value (this should be the first row from the
MResult).
This results show that I've a valid connection and/or query. And when I

which is the desired row), it returns me a non-NULL value too. From
this

I don't want to have to setup a new account for all the users because a) that another account I have to maintain b) the users would hate it. If anyone has any ideas please tell me.

Foreign keys in MySQL
Hi, In the MySQL documentation, it is stated that foreign keys in SQL are not used to join tables, but are used mostly for checking referential integrity (foreign key constraints). Does it mean that constraints are not supported? I need to have Update and perhaps Delete Referential Integrity.

Subject: Bug with AUTO_INCREMENT
Hi,
Continuing my troubles with AUTO_INCREMENT (which nobody has yet
responded to), I've now ruled the Perl DBI out of the equation and
reproduced the same problem using the mysql.exe command-line tool.
Hopefully somebody will be tempted to help this time now that there is
no Perl involved to put people off?
The bug can be reproduced as follows:
Create the following simple database containing just one BDB table:
CREATE DATABASE test;
CREATE TABLE foo (
id INT NOT NULL AUTO_INCREMENT,
num INT,
str VARCHAR(10),
PRIMARY KEY (id)
) TYPE=BDB;
Now start two mysql.exe sessions running with the -f flag to ignore
errors.
Set each one into no auto-commit mode with:
SET AUTOCOMMIT=0;
and then feed each of them the following two lines 50,000 times each:
INSERT INTO foo (num, str) VALUES (1, 'a');
COMMIT;
On my NT4 machine I do this with the simple Perl program (I know I said
Perl wasn't involved, but the Perl DBI still isn't):
sql.pl
--
print SET AUTOCOMMIT=0;\n;
for (1 .. 5) {
print INSERT INTO foo (num, str) VALUES (1, 'a');\n;
print COMMIT;\n;
}
I pipe the output from this to the mysql.exe programs, and then
re-direct STDERR from that to log files, e.g.:
Command Prompt One:
\perl5\bin\perl.exe sql.pl | \mysql\bin\mysql.exe -f -u root test 2
session1.txt
Command Prompt Two:
\perl5\bin\perl.exe sql.pl | \mysql\bin\mysql.exe -f -u root test 2
session2.txt
When I inspect the output collected in these log files I find, not
unexpectedly, that there are many deadlock errors (which I'm quite
comfortable with, and can handle in my real software by simply retrying
the transaction), but that there are also a few of the following error:
Duplicate entry '1' for key 1
Surely this is a bug isn't it?
The transaction that is being performed 50,000 times each by the two
mysql.exe sessions doesn't specify any value for the AUTO_INCREMENT
column id - it just leaves it up to the database to choose the next
value.
This error suggests that the database has wrongly chosen the value '1',
and then (rightly) complains that it is already used!
I would really appreciate a response on this one as I'm now at the end
of my tether trying to work out what is wrong.
Thanks in advance,
Steve

I don't think it is because (a) the last value that was successfully
INSERT'ed - usually around 40,000-odd - is well short of the maximum
INT, and (b) it doesn't always fall over after some particular number of
iterations - it falls over at different, apparently random, times each
time I try the test.

Re: Replication (possible) problems | 'show binlog' command is broken?
Mihail, Are you still experiencing these problems? We've seen the same thing happen our 2 of our slaves. It seems to happen for a day or two and then go away. We've done a snoop while this happens and it looks like the master is closing the socket to the slave. However, the master reports no errors in it's logs. Mysql support suggests that it might be a hardware or os bug. I'd like to rule this out and get them to look further into the problem. Can you describe your hardware/os setup of the master and slave and the network connecting them?

Hi,
My opinion:
This can be a very good reason to kill the socket(is a file too) which is
open during query.
This error show you that you have too many open files in the system.I
tested
something like this(Linux - Red Hat 7.2) some time ago and after 2000
(this
mean sockets) clients connected this error occured.

And every once and a while:

Re: Read-Only MySQL
Microweb provides exactly that. I haven't used it, but I did research on comparing it with running Apache from a CD-ROM. Currently I'm leaning toward the Apache implementation, because PHP will run as a dll, rather than through CGI. But if we need a database, I'll probably go with the Microweb solution (though the Apache version is free). Microweb is pretty clever with MySQL -- if it's read-only, it'll run from the CD, otherwise, it'll copy the tables to a temporarly location on the user's harddrive. I'm not sure how licensing is handled, though. Tac From http://www.indigostar.com/microweb.htm: MicroWeb allows you to create a working web site on a CD-ROM. Using a web browser, a user can run CGI programs as well as view html files on the CD-ROM. To view the website the end user only has to run the microweb.exe program on the CD-ROM, there is nothing to configure. This will automatically start a web browser for viewing the website. MicroWeb provides support for MySQL, it will automatically start a MySQL server if one is included on the CD. - Original Message - From: Colin Faber [EMAIL PROTECTED] To: Gerald R.

Re: auto-increment usage question
Hi, I have a mysql table which has a run_id which together with user_id forms the primary key for the table. run_id is not null and auto-increment. I delete records from this table, and add new records. I want the run_id to keep incrementing and not reuse values, but here is the actual behavior: When records are deleted, upon the next insert run_id will be given a value which is one higher than the greatest value remaining in the table. If the table is empty, run_id will be assigned '1'. Is there any way in which I can get run_id to keep incrementing and not be based on the current highest value in the table, but on the last assigned run_id even if that record has been deleted? If not, are there any common workarounds?

Re: Foreign keys in MySQL
* Hanxue Lee In the MySQL documentation, it is stated that foreign keys in SQL are not used to join tables, but are used mostly for checking referential integrity (foreign key constraints). This could have been formulated in a better way, IMHO. I would even say the statement is wrong. In RDBMS terminology, a 'foreign key' is one (or more) column(s) in a table identifying records in a different table. Consider this schema: CREATE TABLE owner ( id int primary key, name varchar(30)); CREATE TABLE pet ( id int primary key, owner int, name varchar(30)); The 'owner' field of the 'pet' table is a foreign key if it used to store the primary keys from the 'owner' table. It _is_ a foreign key, even if no foreign key _constraints_ have been defined. The FOREIGN KEY keywords in MySQL is used to define such _constraints_, not to define the foreign key itself. Maybe the phrase in the manual should have been something like: ...the FOREIGN KEY keywords are not used to join tables, but... Does it mean that constraints are not supported? Why did you think that? The statement you quoted says ...not used to join tables... used mostly for... foreign key constraints. Anyway, the answer is 'yes and no', foreign key _constraints_ are supported, but only if you use InnoDB tables. Using the FOREIGN KEY keywords on other table types will not give errors, but it will be ignored. I need to have Update and perhaps Delete Referential Integrity.

I don't think it is because (a) the last value that was successfully
INSERT'ed - usually around 40,000-odd - is well short of the maximum
INT, and (b) it doesn't always fall over after some particular number of
iterations - it falls over at different, apparently random, times each

Subject: Bug with AUTO_INCREMENT
Hi,
Continuing my troubles with AUTO_INCREMENT (which nobody has yet
responded to), I've now ruled the Perl DBI out of the equation and
reproduced the same problem using the mysql.exe command-line tool.
Hopefully somebody will be tempted to help this time now that there is
no Perl involved to put people off?
The bug can be reproduced as follows:
Create the following simple database containing just one BDB table:
CREATE DATABASE test;
CREATE TABLE foo (
id INT NOT NULL AUTO_INCREMENT,
num INT,
str VARCHAR(10),
PRIMARY KEY (id)
) TYPE=BDB;
Now start two mysql.exe sessions running with the -f flag to ignore
errors.
Set each one into no auto-commit mode with:
SET AUTOCOMMIT=0;
and then feed each of them the following two lines 50,000 times each:
INSERT INTO foo (num, str) VALUES (1, 'a');
COMMIT;
On my NT4 machine I do this with the simple Perl program (I know I said
Perl wasn't involved, but the Perl DBI still isn't):
sql.pl
--
print SET AUTOCOMMIT=0;\n;
for (1 .. 5) {
print INSERT INTO foo (num, str) VALUES (1, 'a');\n;
print COMMIT;\n;
}
I pipe the output from this to the mysql.exe programs, and then
re-direct STDERR from that to log files, e.g.:
Command Prompt One:
\perl5\bin\perl.exe sql.pl | \mysql\bin\mysql.exe -f -u root test 2
session1.txt
Command Prompt Two:
\perl5\bin\perl.exe sql.pl | \mysql\bin\mysql.exe -f -u root test 2
session2.txt
When I inspect the output collected in these log files I find, not
unexpectedly, that there are many deadlock errors (which I'm quite
comfortable with, and can handle in my real software by simply retrying
the transaction), but that there are also a few of the following error:
Duplicate entry '1' for key 1
Surely this is a bug isn't it?
The transaction that is being performed 50,000 times each by the two
mysql.exe sessions doesn't specify any value for the AUTO_INCREMENT
column id - it just leaves it up to the database to choose the next
value.
This error suggests that the database has wrongly chosen the value '1',
and then (rightly) complains that it is already used!
I would really appreciate a response on this one as I'm now at the end
of my tether trying to work out what is wrong.
Thanks in advance,
Steve

MySQL DateTime subtraction question
This question relates to both mysql in general and the mysql++ C++ API in particular, thus the adressing to both lists. I have a DateTime object (really a formatted string) say 2002-07-10 11:38:38. I want to subtract some variable number of hours (from 0 to 11) from it. How do I accomplish this in an elegant manner? There is quite a bit of logic to handle all the cases where subtracting hours takes the date one day back, which can take the month one month back, which can take the year one year back! And of couse all the months have different lengths so this can be some ugly code. I can do this the hard way, but I was wondering if anyone already has a nice solution.

RE: Replication - Error reading packet from server: (server_errno=1159)
Thanks, I had a look at that and it seems that slave_net_timeout is the variable that should be used and this is set to 3600 seconds - however it appears that the net_read_timeout is being used and by changing this from 30 to 3600 seconds the messages seem to have gone away. In the 3.23.38 version we are using with our other slaves they never timeout and the slave_new_timeout variable doesn't exist - it would seem that some code has been introduced to allow the slave connections to timeout but is using the net_read_timeout variable rather than the slave_net_timeout variable as I would expect.

RE: MySQL install on Linux 7.1
Are you using RPM or installing from source, i.e. running make? Also if you need to find where files are located change to root directy cd / then type find -name mysql that will get you started as to where your mysql files are located. The find command is very helpful when searching for files, its very similar to windows start menu search utility. Just make sure you change to the most parent directory to run the search, as find traverses from the Present Working Directory PWD forward. Also the best doc I have found is on the mysql.com site itself: http://www.mysql.com/doc/ You will find everything you need there... Good Luck and Welcome to Linux.

sorting values not so easy!
Hi guys, I have a problem sorting values comming out of a db. It is not as easy. Here is the prob: One table containing user points. Other table containing reports with rankings For each top 10 report (the 10 reports with the most ranking) there are 20 extra points granted Now I would like to get the top 5 members out of the db. If I only pull out the user table ordered by points desc limit 5 I might miss a user with a top 10 report and 20 extra points. So I thought about sorting the array afterwards with asort, but then I loose the asoziation with the user_id. Maybe there is a way to sort the other arrays with the same sorting algo? Or a way to include a iff clause in the query? currently I am doing: SELECT u_name, id, points FROM user WHERE points 0 ORDER by points desc LIMIT 5 and the top10 reports extra. Has anybody a good idea on that?

You probably have only granted permission, for the user you are connecting as, to the localhost where MySQL is installed use mysql; SELECT * FROM user\G This will show all users able to connect to mysql server and from what host address. Check the ip of the computer you are connecting from and see if it in there. If not, try: GRANT some privileges on database.table to 'username'@'10.10.10.%' identified by 'password'; ^^^ can be wildcard *.* or database.* Check the GRANT section in the mysql manual. If you are connecting to the server from windows, you may want to use the -u option, which is the user name on the mysql server, just incase your windows username does not match : mysql -u username hmm, what else... try that for now - 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?

help in re-thinking a way to do the following:

Given the following code:
$sql = qq! select * from table where suffix1 ''!;
$db_action = $DB-prepare($sql);
$db_action-execute or die could not do $sql - $DBI::errstr;
$rows = $db_action-rows;
$rec = $db_action-fetchall_arrayref;
$db_action-finish;
for ($i=0;$i$rows;$i++) {
$id = $rec-[$i][0];
$first_name = $rec-[$i][1];
$last_name = $rec-[$i][2];
$identifier = $rec-[$i][3];
$prefix1 = $rec-[$i][4];
$suffix1 = $rec-[$i][5];
$prefix2 = $rec-[$i][6];
$suffix2 = $rec-[$i][7];
$site = $rec-[$i][8];
$location = $rec-[$i][9];
$phone_loc_id = $rec-[$i][10];
I would like to find alternate ways to do this that would take into account
changes to the table. For example let's say that the table changes (for
example lets say that site field in the above example is removed). What I
am interested in, is how are others in the group are handling this type of
thing. I have heard something about tying column names - not sure what this
is. Any and all suggestions will be most appreciated.

There is quite a bit of logic to handle all the cases where subtracting hours takes the date one day back, which can take the month one month back, which can take the year one year back! And of couse all the months have different lengths so this can be some ugly code. I can do this the hard way, but I was wondering if anyone already has a nice solution. Are you going to be doing this often (e.g., dateroll conventions, holiday/weekend avoidance). If so, your object should be smarter than just keeping the string. E.g., it might want to have a notion of the julian date, time in UTC, etc., etc. Convert the date to struct tm, call mktime(). You now have number of seconds since the epoch of 1970. Subtract x-hours * 60 minutes * 60 seconds. Convert back to a struct tm, and fire off strftime.

MySQL List
I've sent a couple of messages to the MySQL list today that didn't seem to
get through. Have there been any problems with the list and/or the manager
today? One of them was returned as being too large to be posted and it
really wasn't all that long. One of them never made it through and was never
returned. This one was originally returned as spam since it didn't contain
any words related to sql, mysql or query. Are the list filters or posting
rules available somewhere to read?
Here's the question I had earlier from the first message that was returned.
I have a small c program that is supposed to run a select query against a
MySQL database. It keeps bombing with a segfault during what I think is the
db connect. I recompiled everything with debug and ran mysql_debug in the
code and am getting the following:
1: dbug: libmysql.c: 1176:1: mysql_real_connect

It doesn't generate a core dump by the way. If I run a strace on the same

sin_addr=inet_addr(192.168.5.3)}}, 16) = -1 ECONNREFUSED (Connection
refused)
shutdown(3, 2 /* send and receive */) = -1 ENOTCONN (Transport endpoint is
not connected)
close(3)= 0
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
Any ideas what error 111 and/or 2003 is? Other thoughts?
The actual debug used in the code is:
mysql_debug(d:t:F:L:n:N:P:o:, /tmp/client.trace);
The username/password/host/database all work fine from the mysql client as
well as from other programs that use similar shared code as the one that's
broken.

Diagnosing frequent table corruption error 127.
One of our servers (of many running the same software and mysql version) is frequently getting ERROR 1030: Got error 127 from table handler on two of its tables. mysql version is 3.23.49. We can not recover with myisamchk -r, but instead have to use myisamchk -o which ends up wiping out the offending record(s). We've tried to correlate this to some unix process which might interrupt writing to the file, but can't find any pattern. Does anyone have a good methodology for diagnosing these corruptions? We can possibly suspect hardware problems (old rack-mount server) but having done a lowlevel filesystem check, no errrors come up. The two tables involved are almost exclusively used with INSERT statements, and they do contain around 25 rows, What else can lead to such frequent errors on the same tables?

Re: Replication - Error reading packet from server: (server_errno=1159)
Yeah, I'm getting these errors all the time on 3.23.51, also. I agree that the slave_net_timeout variable is definitely not being paid any attention. However, I'm not comfortable just upping the net_read_timeout without knowing what other effects it might have. --jeff - Original Message - From: Mark Hughes [EMAIL PROTECTED] To: Nilesh Shah [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Wednesday, July 10, 2002 9:57 AM Subject: RE: Replication - Error reading packet from server: (server_errno=1159) Thanks, I had a look at that and it seems that slave_net_timeout is the variable that should be used and this is set to 3600 seconds - however it appears that the net_read_timeout is being used and by changing this from 30 to 3600 seconds the messages seem to have gone away. In the 3.23.38 version we are using with our other slaves they never timeout and the slave_new_timeout variable doesn't exist - it would seem that some code has been introduced to allow the slave connections to timeout but is using the net_read_timeout variable rather than the slave_net_timeout variable as I would expect.

Re: [PHP-DB] Re: subtracting one query from the other
Dear Dan, Thanks for your timely help. Yes, removing the concatenation has reduced the running time nearly 10 times . So finally my sql looks like the below, SELECT distinct a.playlist,a.material_id,a.destination_locator,a.destination,a.air_time,a.traffic_duration,a.comment,a.title,a.device_name,a.source_locator,a.source from cch_dubber_dublist_view_a1 a left outer join cch_dubber_dublist_view_b1 b ON a.material_id = b.material_id AND a.destination_locator = b.destination_locator AND a.device_name = b.device_name where b.material_id is null The number of records returned is 3566. The time it takes is 18 seconds. My boss wants it to run in 4-5 seconds. If the number of records r more like 4-5000 then it takes even longer. How can i reduce the time even further. Can i index the tables or nething will that help. Help is greatly appreciated. Thanks, Regards Harpreet Kaur From: [EMAIL PROTECTED] (Dan Kokenge) To: [EMAIL PROTECTED] (Harpreet Kaur) Subject: Re: [PHP-DB] Re: subtracting one query from the other Date: Tue, 02 Jul 2002 00:33:21 -0400 Hi Harpreet SELECT distinct a.playlist,a.material_id,a.destination_locator, a.destination,a.air_time,a.traffic_duration,a.comment,a.title, a.device_name,a.source_locator,a.source from record1 a left outer join record2 b on a.material_id+a.destination_locator+a.device_name=b.material_id+b.destination_locator+b.device_name where b.material_id+b.destination_locator+b.device_name is null Not sure why you concatenate the fields together. This will take some time to bring the fields together before the compare. Why not simply compare the separate fields. Also why do you compare all the fields for null. Seems like you only need to compare the material_id, that is of course you don't have a matching material_id that can be null - and I doubt that. SELECT DISTINCT a.playlist, a.material_id, a.destination_locator, a.destination, a.air_time, a.traffic_duration, a.comment, a.title, a.device_name, a.source_locator, a.source FROM record1 a LEFT OUTER JOIN record2 b ON a.material_id = b.material_id AND a.destination_locator = b.destination_locator AND a.device_name = b.device_name WHERE b.material_id is NULL - if you need all three you can change the where to: WHERE b.material_id is NULL AND b.destination_locator is NULL AMD b.device_name is null Actually this is a fairly common type command and I use it a lot. I don't know anything about your files. You didn't mention how large the files were. If they are huge the time may be ok. If not you may want to see if it's it indexed properly. A index on material_id at a minimum. If this file is fairly static, with only a few inserts and deletes a minute, then I'd index the hell out of it, and put an index on all 3 fields. If it's a vary active file with lot of inserts and deletes, then you have to be careful on your index scheme. Also if one file is vary large and one very small, then it is much faster to read the smaller file id's into arrays, and then read the large file and see if it has a matching id in the array. I've been called in to consult on problems where I've had to do 6 or 7 joins against huge files that I've dropped run time from hours to less than 5 minutes doing the array thing. HTH.. Good luck..

Re: Mass Delete
personally, i'd just use perl:
my @deademails = (long, list, of, emails);
take the output of:
select email from table
drop that into another array (@allemails)
then do a for loop through all the emails
checking to see if each line of @allemails matches any line of @deademails
if it does
kill it
for (my $i = 0; $i = scalar(@allemails) - 1; $i++) {
for (my $x = 0; $x = scalar(@deademails) - 1; $x++) {
$killit = 1 if $allemails[$i] eq $deademails[$x];
}
if ($killit) {
enter delete query here
}
}
wo
that's way more complicated than it has to be
you could also just loop through all @deademails
and do a delete from table where email='$deademails[$i]'
for (my $i = 0; $i = scalar(@deademails) - 1; $i++) {
delete statement for $deademails[$i]
}
either way should work
i only kept the top one 'cause i spent so long writing it
it would just seem wrong to delete it all now
good luck :)

I have tried reseting the master and slaves but didn't change anything. Also tried redumping the databases to the slaves but that didn't effect anything. Anyone have any ideas?

Re: Mass Delete
Not surprisingly, I'm still confused. Could you hold my hand?
Here's what I've got --
This is my table --
CREATE TABLE churchmail (
email varchar(30) NOT NULL
);
It has one field containing 40,000 email addresses.
I have a text file -- remove.txt, which contains 1,500 email addresses
which need to be removed from the churchmail table. The database is
named midtn. I think it's the two WHERE clauses that are throwing me.
Whatever it is, I remain stuck, and would appreciate assistance. I'd
like to do this on the command line, no PHP.
Thanks,
Robert

I have about 40,000 email addresses in a MySQL database.
I also have a list of 1500 email addresses that need to be removed.
I am searching for a way to delete these 1500 email addresses en masse,
but I have come up short.
I sure would appreciate a nudge in the right direction from somebody who
might be in the know.

help with MySQL SELECT statement
Easy question I hope, relatively new user ( 6 months) here wanting to know how to fashion a MySQL select statement based on the following: there is a list of managers and their email addresses. This list changes all the time as we add and subtract different companies from the db. I would like to check the domain name of a form submitted email address against the list of domain names in the db. But I don't want to select the entire email list (1000's) when there are probably only 100 max different domain names (i.e. alltel.com, ualr.edu, etc.). Is there a way to do this? It would lighten the server load and the download times for the form page if possible. thanks!

Re: help with MySQL SELECT statement
wait, how will the MySQL SELECT DISTINCT pick only one between these two addresses (as an example): [EMAIL PROTECTED] [EMAIL PROTECTED] I only need one email address each for alltel.com, one for ualr.edu, one for target.com, etc. when there might be 50 email addresses from each of those domains. I intend to then parse the adresses leaving only a list of whatever.coms which I will stick into an array for my validation function to use. Or am I making a mountain out of a molehill here?

RE: help with MySQL SELECT statement
I'm not exactly sure if this is the right syntax. I can see that maybe a couple of domains would get cut out of this if there spelt almost the same. What you need to find out is the char count of the smallest domain name. Then replace smallestdomain with that number. What the rest of the select statement does is only get the last so many chars up to the smallest domain name and then the distinct will only return those that are not the same. I'm sure you can work around with this and find something that will do exactly what you want.

how do I fix corrupt .MYD file?
I have a database in which one MYD file has apparently been corrupted: mysql use tracerlock; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Didn't find any fields in table 'news_feed_item' Database changed mysql select count(*) from news_feed_item; ERROR 1016: Can't open file: 'news_feed_item.MYD'. (errno: 145) mysql The other tables in the database still work. How do I fix this one? I have no idea how it happened. If I open the file in a text editor, I can see the data from some of the records that have been entered. I've rebooted the machine to no avail (I figured that wasn't the problem, but I tried). I have a backup of the table dated last Saturday, but I'd prefer to fix this version if possible to preserve the entries entered between Saturday and Wednesday. -Bennett [EMAIL PROTECTED] http://www.peacefire.org (425) 649 9024 - 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?
