Re: join from two different databases

The database handle defines the default database. So if your database handle is on the receivables database, your query can be: my $q = "SELECT i.inv_no, i.inv_date, c.cust_name FROM invoice i, sales.customer c, WHERE i.paid_date IS NULL"; I.e. invoice i.s.o. receivables.invoice. Your query above will work regardless of the database that your handle is for. The only limitation is that the databases are managed by the same MySQL server. Just try it. One more thing about your query. You're doing a full join of the two tables. You probably want something like "AND i.customer_id = c.id" in the WHERE clause.

Re: am I alone? (scale)
hey.. thanks for the info... This is the my.cnf file that i'm using - [mysqld] skip-locking set-variable= key_buffer=640M set-variable= max_allowed_packet=10M set-variable= table_cache=640 set-variable= sort_buffer=6M set-variable= record_buffer=6M set-variable= thread_cache=16 set-variable= thread_concurrency=16 set-variable= myisam_sort_buffer_size=64M log-bin server-id = 1 set-variable= max_connections=2000 set-variable= max_connect_errors=1 set-variable= back_log=2900 set-variable= connect_timeout=15 set-variable= wait_timeout=57600 set-variable= interactive_timeout=57600 Now the problem that i've managed to track down is - When the CPU hits 100%, mysql crashes. This behaviour has been consistent across many many runs. I would definitely not like the database server to crash. A loss in performance is expected but a crash is most definitely not. As u can see, the limits are set pretty high on the system. Memory usage is not even 150MB. What's the reason? and the partial backtrace that i'm getting is the same after every crash. Any ideas? Tx.

I was also going to measure these, but have not had time yet. But what parameters you used in my.cnf? You have a lot of RAM in your system, and you could make the Innobase buffer pool big. I've tested with the default innobase parameters mentioned in the documentation. 1. cat test.sql | mysql innobase = 306 seconds 2. cat test.sql | mysql innobase, but with autocommit=0 and all inserts between BEGIN/COMMIT = 124 seconds If you use autocommit = 1, then Innobase has to flush the log to disk after each individual insert, which makes it slow. It is better to use autocommit = 0, if you have enough space in your tablespace for the rollback segment. ok, I understand. 3. same as 1. but with index creation after the inserts. = 264 seconds + additional 59 seconds for index recreation. 4. same as 2. but with index creation after the inserts. = 75 seconds + additional 59 seconds for index recreation. How do you create the index? With ALTER TABLE? yes, exactly. I noticed that in 3. and 4. the machine load was constantly at 100% during the inserts. but during index recreation the load springs wildley between 0 and 100%, so the machine is not maxed out in terms of CPU utilization here (in other Innobase has to write to the log which causes some disk i/o, reducing CPU utilization. Also, when the database has written the log files full, Innobase has to make a checkpoint, that is, flush written pages from the buffer pool. You could try making your log files very big, say 150 MB in total, to get a better CPU utilization, and also the buffer pool bigger, if it is not yet big. ok, I will try the benchmark with tweaked values for innobase again. Totally the opposite of spam! I got useful information from this! ok, thanks !

Tuple length Question
Hello All: I am looking into mysql as a web solution. I am implementing a multilanguage scheme. I am considering separating the different languages by the following three methods. 1. Use different tables to hold different languages. 2. Use the same table with another key (lang). 3. Add extra attributes to a table and pick the ones containing the language I want. I am exploring possibility number 3 at the moment. My question is, how long can a Mysql myisam table tuple be? Currently I like the idea of increasing the number of attributes except for this possible constraint. I might have 6 to 10 languages supported max. I'll start with 2. I will have no more than 15 attributes total and possibly 5 will be shared between languages. This means i'll have to add another 10 attributes per language implemented. Thanks in advance.

RE: Persistent connection with php to mysql
I prefer persistent connections because you save time not having to rebuild the connection each time. As to how, the actual call to mysql_pconnect is buried deep in my framework and it's kinda hard to explain how I do it. I would NOT suggest that you store it as a session variable. That kinda defeats the purpose of using connection pooling. Yes, you could put the code in an include file.

RE: ROWNUM???
Hi Peter, I'm not sure but I don't think it's possible with MySQL. The best you could do is make sure you have a primary key on the table that is autoincrement. This will give you a unique number for each row. RowNum is very subjective since it is describing the row number in the cursor you are looking at in. Most RDBMS' do not assign (or at least do not expose) a table level row number. If you absolutely must have one then you have 2 options that I can see. 1: Create a field in your table and assign it manually. This works at the table level but is fairly useless info at the cursor level. 2; Do it in your procedural language. As you said, it's trivial to implement in PHP and IMHO that's where it should be done.

very strange but reproducable error in 3.23.35
Hi, i just upgraded from 3.23.33 to 3.23.35 and found that a little script of mine which simply modifys a table went mad completly.

Re: BACKUP TABLE gives access denied
Check the manual to make sure, but I believe that you need to also make sure that the operating system privileges are set correctly too. Not sure what you'll need in Windows, but in Linux, your hosting company probably runs MySQL under the user mysql. Thus, for the database to write out the data for BACKUP, it needs _unix_ write privileges for user mysql (can be group too). If you are trying to backup a table to a directory in your log-in directory, you need to make sure that the MySQL daemon has write privileges to the backup directory.

Re: very strange but reproducable error in 3.23.35
Hi!

What error message do you get ??
What i wrote was all i got - so there's just
mysql update t_webmaster set status=1 where type='Open';
Query OK, 0 rows affected (0.01 sec)
No other messages at all - simply repeating the query _does_ show the
expected.
- no message in the error log (...would have mentioned this... ;-)
- no special thing in the normal log:
010318 20:41:44 7 Query alter table t_webmaster change lfdnr
lfdnr int(10) unsigned default 0 not null auto_increment
010318 20:41:48 7 Query update t_webmaster set status=1 where
type='Open'
010318 20:41:49 7 Query update t_webmaster set status=1 where
type='Open'
(only 2nd "update" did something)
...just did some more tests - perhaps this is relevant for this case:
If i re-create this test table with "mysql mydb testcase.sql"
("testcase.sql" includes a "drop table t_webmaster"), and do a
myisamchk -vv /usr/local/var/ticketeer/t_webmaster.MYI
immediately afterwards, i get:

Er. Is there any way you guys can actually form a stable branch, and a development branch? It would be nice to get a stable version of mysql with replication, and that's not going to happen with all of these new features being pumped into a supposedly "stable" branch. Don't enable innobase or gemini, and you'll have a stable server. Seriously, if you don't even compile in the new features, there's little danger of them affecting you. Jeremy Little danger?! Look, let's approach this another way. 3.23.xx isn't stable, and hasn't been ever, because it _was_ a development branch, and you keep treating it as such, while at the same time you call it your stable branch. This is wrong. Perhaps you haven't heard of such a thing as a development branch, and stable branch of code. Maybe you haven't heard the term "beta" and "alpha" ever before. 3.23.xx is BETA, and unusable in a production enviroment. Maybe I should say that again. 3.23.xx is BETA, and is unusable in a production enviroment. You need a stable branch, and a development branch, and you need them ASAP so that current MySQL code can be made stable enough for a production enviroment. Don't take this the wrong way. MySQL is a great product, but any great software product is a piece of crap if its crashing and causing problems because you keep it in a consitantly beta state.

ATTENTION: bug fix for Innobase non-latin1 character sets
Readers of the mailing list!
There is a serious bug in the non-latin1 character set support of
Innobase. The bug causes indexes to be sorted in a wrong order, and
queries to return wrong results. The bug explains why test-ATIS returned
wrong results in a Russian installation.
I assumed that the function my_sortncmp returns -1, 0, or 1, but actually
it returns a difference of ASCII codes for characters.
You can fix the bug by editing the file mysql/sql/ha_innobase.cc,
function innobase_mysql_cmp, about line 920, the function
should be like the following:
snip
extern "C" {
/*
Innobase uses this function is to compare two data fields for which the
data type is such that we must use MySQL code to compare them. NOTE that the
prototype of this function is in rem0cmp.c in Innobase source code!
If you change this function, remember to update the prototype there! */
int
innobase_mysql_cmp(
/*===*/
/* out: 1, 0, -1, if a is greater,
equal, less than b, respectively */

[philb@gnu.org: Bug#88186: mysql: Fails to build on ARM: char sign issue?]
Hi Hope this helps you to make mysql working on ARM architecture, too. bye, -christian- -- Christian HammersWESTEND GmbH - Aachen und Dueren Tel 0241/701333-0 [EMAIL PROTECTED] Internet Security for ProfessionalsFax 0241/911879 WESTEND ist CISCO Systems Partner - Premium Certified This isn't actually a signed-char issue. The signedness problem comes about because mysql's configure script is spuriously selecting "int" rather than "socklen_t" as SOCKET_SIZE_TYPE. The root cause is actually that the configure script tries to build things with "-g -fomit-frame-pointer -Werror". Mixing -g and -fomit-frame-pointer always elicits a "may not give sensible debugging" warning; combined with -Werror this means that every test is deemed to have failed. For ARM, the performance gain from -fomit-frame-pointer is going to be marginal anyway so the best thing to do is probably just to take it out. p. - 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: request - insert into merge tables
Hello. On Mon, Mar 12, 2001 at 05:16:59PM -0600, [EMAIL PROTECTED] wrote: Seems like it would be relatively easy to implement inserting into merge tables. I'd like to be able to at an absolute minimum round-robin insert, but even better would be something like you can do with partitioning in oracle. Baically, something like this: create table x (...) type=merge union=(a,b,c,d) partition=a:(where key=val1) partition=b:(where keyval2 and keyval3); [...] While I completely agree that some sort of INSERT into MERGE tables would be really nice (to avoid the need to change the program), I don't see how this falls under "relatively easy to implement". MySQL doesn't even have yet expressions as default values for columns. But maybe you meant it another way. For a first start I would suggest two variants, which shouldn't be to hard to do, because no new specs are needed: round-robin, as you suggested and first resp. last. The latter one is needed for logging tables, where you want all new rows go into the same table.

importing data into a table with auto_increment
hi there, is there a problem with importing data into a table with an auto_increment field with a primary key, if the data contains values for the auto_increment field? I keep getting an error that it can't insert the value "1" more than once. However, all the values for the auto_increment field are unique (though not consecutive) - and if I create the table with the field as a normal int, then the import is successful and all values for the int field are indeed unique. I could not find anything in the manual describing this behaviour. I've also tried sending this post with the data file (small) and commands used but unfortunately it gets rejected by the anti-spam software and 3 attempts later I couldn't work out why, so I hope this is enough information thanks dan - 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?

Creating bitmask for SELECT against type SET
Recently, I'm having to match against SET columns quite a bit. Is there a
fast way to create a bitmask of set data?
For example: A user table has interests as set ('ABX','BX','CXX'...)
I want to select users where interests include ('CXX','NNX'...)
Method 1: select them one at a time
SELECT * from users where interests LIKE "%CXX%";
SELECT * from users where interests LIKE "%NNX%";
etc.
Method 2: the same thing using OR
Select * from users where interests LIKE "%CXX%"
OR interests LIKE "%NNX%"...
I would prefer to do this:
-Make a bitmask of ('CXX','NNX'...)
-Select WHERE interests bitwise-or bitmask
As far as I can tell from the documentation of Find_In_Set(), I am on my
own to make the bitmask... first selecting the column definition, and then
using find_in_set iteratively on that column definition for each member I
want to match. This seems a pain, since MYSQL creates the number I want
by itself every time I write a record to the table!
(Yeah, I know that another possibility is to create a joined
table rather than use the set type, but this is a lightweight
application... a few thousand users, about 30 interests, and
only a handful of these matches a week. I'm just trying to
clean up the code.)

I have code that does this by reading the SET column definition from
SHOW COLUMNS output, then uses it to allow a set of corresponding
checkboxes from a form to be converted into a bitmask. That allows
you to perform numeric testing against SET column values. The code
is in Perl, lemme know if you want it.

If the bug only affected parts of the release that are still alpha, beta or gamma, as some of the new table types are, then the change notice should really reflect that, so that a new user is sure of what is affected, aiding the 'To upgrade or not upgrade' decision.

Re: There must be an easier way to search!
Hello, this is how I'm searching a database now...is there an easier way (PHP)? Anything that's short would be nice. This is just really long. You can do something like this: $searchgenre = "'punk','hardcore', 'classical', 'acoustic'"; $sql_text = "SELECT * FROM artists WHERE genre in ($searchgenre) ORDER BY artist ASC"; Alternatively, look at the SET and ENUM datatypes if your genres are pretty static. - 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: Tuple length Question
Leo, There's another alternative that I found intriguing with MySQL that I haven't tried - but it might be a really good solution for you. Mind you I haven't tried this, but I found the idea somewhat fascinating. Have you looked into the temporary table functionality of MySQL? Suppose you have n tables with languages like this: language_english language_french language_spanish language_german Now when you establish your connection to the database, do this: create temporary table language select * from lang_english // pick your lanuage in code Now the rest of you code can refer to "language" as a table -- and you can add as many languages as are needed modifying only the stub of code that initially selects the language. - Original Message - From: "Leo Cambilargiu" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, March 18, 2001 8:30 AM Subject: Tuple length Question Hello All: I am looking into mysql as a web solution. I am implementing a multilanguage scheme. I am considering separating the different languages by the following three methods. 1. Use different tables to hold different languages. 2. Use the same table with another key (lang). 3. Add extra attributes to a table and pick the ones containing the language I want. I am exploring possibility number 3 at the moment. My question is, how long can a Mysql myisam table tuple be? Currently I like the idea of increasing the number of attributes except for this possible constraint. I might have 6 to 10 languages supported max. I'll start with 2. I will have no more than 15 attributes total and possibly 5 will be shared between languages. This means i'll have to add another 10 attributes per language implemented. Thanks in advance.

CREATE TABLE authorsofdoc ( docid INTEGER UNSIGNED NOT NULL, authorid INTEGER UNSIGNED NOT NULL, constraint pk_authorsofdocPRIMARY KEY(docid, authorid) ) Now what the heck does the 4th line do? i have never seen a syntax like that in the CREATE TABLE syntax...wats all that 'constraint pk_authorsofdoc' and after that 'PRIMARY KEY()' option infact acording to CREATE TABLE syntax it should be...

Technical Clarification
hi,
This is kathir from Uniware Systems, We are developing project on ASP with Backend
as MySQL, We having a problem using "IN" and "NOT IN" operators in sub query
here i am listing my query as follows:
"select c.pickupdate,c.contno, r.relrefno, r.custname, r.contsize, r.conttype,
r.qtybooked from contpickup c,releaseauthor r where c.relrefno=r.relrefno and
c.relrefno in(select relrefno from contpickup where contno='" ccode "') and
c.contno not in (select contno from billlading where relrefno in(select relrefno from
contpickup where contno='" ccode "'))"
iam selecting the values from 3 different tables using in and not in operators. When
iam executing the above query it displaying the error as follows:
[TCX][MyODBC]You have an error in your SQL syntax near 'CRXU9021208'')' at line 1
for ur clarification the simple query is also not executing using IN operator.
select relrefno from releaseauthor where relrefno in
(select relrefno from contpickup)
But this statement is executing
select relrefno from releaseauthor where relrefno in
("123","456")
pls.. let me know solutions as earliest for the above query and using IN and NOT IN
operators.
note:
The above query is executing in MSSQL Server 7.0 and Oracle 8.
regards,
kathir (Programmer Analyst)

INSERT INTO Table problems
Okay, another question from the stumbling idiot: what's wrong with this code:
$insert_query = "INSERT INTO news (NewsID, Title, Date, Author, Source, Link,
Information, Status) VALUES ('', 'asdf', '2001-03-19 00:33:47', '1', 'asdf', 'asdf',
'asdf', '2') LIMIT 0, 30";
$insert_result = mysql_query($insert_query);
Anything?
$insert_result is 0, which means it failed, and it DID fail because the entry is not
in the database. What is weird, is that I copied and pasted that line from
phpMyAdmin, which DID work!! I pulling my hair out!
My eventual question will also be: is this a legal statement? :
$insert_query = "INSERT INTO news (NewsID, Title, Date, Author, Source, Link,
Information, Status) VALUES ($NewsID, $Title, $Date, $Author, $Source, $Link,
$Information, $Status) LIMIT 0, 30";
$insert_result = mysql_query($insert_query);
I guess I was just wondering if I need the ' ' around the variables like '$Title', etc.
But, most importantly is that first question: why would it execute correctly in
phpMyAdmin, and then when I copy and paste the SQL-query from the "Modifications have
been saved" line of phpMyAdmin into a PHP file, run it, and it fail?
Thank you for your assistance.

reusing unique id's when deleting/inserting?
Hi all, Here are two tables I'm working with. I apologize if you are not using a monospaced font and they are messed up. This is used by a gradebook program. When a professor adds an assignment to a class he teaches, it inserts the information about the assignment into the assignments table, and inserts the grade each student receives in the student_assignment table. This happens at the same time so the unique ID is generated the same. When he deletes an assignment from the class, it deletes it from both tables. However, after this, if he adds an assignment again, the unique ID generated by insertion into the assignment table is one greater than it should be - i.e., it auto increments the id based on the id of the row that just got deleted, not on the last row that is actually in the table. When the assignment is inserted into the student_assignment table, the unique ID is auto incremented based on the last ID that is actually in the table, not on the row that just got deleted. The workaround I have found is to use last_insert_id() to find the ID that got inserted in to the assignment table, and use this to manually specify the ID for the student_assignment table. This has the effect of putting the ID's in sync, which is what I want, but it seems like there should be a better solution. Any suggestions?

Re: INSERT INTO Table problems
What's the "LIMIT 0,30" for ?
Also, you should probably do this:
$insert_result = mysql_query($insert_query) or die(mysql_error());
Then you wouldn't need to wait for an answer ;-)

Subject: INSERT INTO Table problems
Okay, another question from the stumbling idiot: what's wrong with this
code:
$insert_query = "INSERT INTO news (NewsID, Title, Date, Author, Source,
Link, Information, Status) VALUES ('', 'asdf', '2001-03-19 00:33:47', '1',
'asdf', 'asdf', 'asdf', '2') LIMIT 0, 30";
$insert_result = mysql_query($insert_query);
Anything?
$insert_result is 0, which means it failed, and it DID fail because the
entry is not in the database. What is weird, is that I copied and pasted
that line from phpMyAdmin, which DID work!! I pulling my hair out!
My eventual question will also be: is this a legal statement? :
$insert_query = "INSERT INTO news (NewsID, Title, Date, Author, Source,
Link, Information, Status) VALUES ($NewsID, $Title, $Date, $Author, $Source,
$Link, $Information, $Status) LIMIT 0, 30";
$insert_result = mysql_query($insert_query);
I guess I was just wondering if I need the ' ' around the variables like
'$Title', etc.
But, most importantly is that first question: why would it execute correctly
in phpMyAdmin, and then when I copy and paste the SQL-query from the
"Modifications have been saved" line of phpMyAdmin into a PHP file, run it,
and it fail?
Thank you for your assistance.

Re: INSERT INTO Table problems
The LIMIT is irrelevant. It doesn't work with or without that there.
I put the die(mysql_error) in and the result wasn't very helpful...
I had another suggestion from a person saying to remove the first set of
column names to make the query like this:
$insert_query = "INSERT INTO news VALUES ('', 'asdf', '2001-03-19 00:33:47',
'1',
'asdf', 'asdf', 'asdf', '2') LIMIT 0, 30";
$insert_result = mysql_query($insert_query);
It works, but aren't those column names there for safety, to make sure the
values are placed in the correct columns?

strange ws_concat,concat result
How come the query
SELECT
CONCAT('"',CONCAT_WS('";"',title,prio,category,program,bugdesc,created,modif
ied,bugstatus,submitter), '"') FROM tbl_bug;
returns something like
"4","4","4"
"10","10","10"
while only
SELECT
CONCAT_WS(';',title,prio,category,program,bugdesc,created,modified,bugstatus
,submitter) FROM tbl_bug;
returns the intended result except that the values are not confined withing
'"'.
that is
Tough Bug,1,3,4,A very long description
I do understand why the second query returns what it returns, but the first
one should not return what it returns, right?
Am I clear enough?
I'm using 2.23.33 on Windows 2000 Server.
