Problem with chars case in naming under WIN98
Description: I started replication from UNIX_server(Distrib 3.23.33) to windows_server(3.23.35a for win95/98). When I creating a table JJJ on a master host, i see table jjj on slave instead of JJJ. And more - any created locally on slave side in upper case table appearing as lower case ... Under UNIX there is no such problem... tables JJJ and jjj are different and can exist at the same time. So, It's impossible to replicate such tables. I can't test slave on other platforms... How-To-Repeat: build replication then do CREATE TABLE JJJ(a char(1));CREATE TABLE jjj(b char(7)); on master side and do SHOW TABLES; on slave(windows platform) side. U'll see an error on slave side and slave side will stop replication process.

Complex mysql query
Hi everybody. I got a complexe question well according to me.

Converting Decimal value to Binary
Hi, WHAT DO I WANT TO DO: I want to have the binary value of a part of a decimal value. 1)I have a decimal value in column called intag : 262204 2)From this value I'am only interested in the last two bits of the HEX value of this decimal HEX value = 4003C My interest 3C part of used SQL query: substring(HEX(intag), (length(HEX(intag))-1), 2) 3)For the last two bits(3C) I like to have the binary value HEX value = 3C Binary = 00 Final SQL query: BIN(substring(HEX(intag), (length(HEX(intag))-1), 2)) PROBLEM When running the last query, the returned value is 11 instead of 00. Probably it has something to do with the fact that I requested a substring of length 2. What do I need to do to get the complete binary value? If one you SQL geniuses knows this, please let me know.

Re: ADO problem with MYSQL datetime column

If these columns are null or 0 - "-00-00 00:00:00", I have problems reading from the ADO recordset. What kind of problems are you having specifically? If you already have your data in an ADO recordset, then it is fairly simple to "massage" the data in any way you want. Have you checked the field with IsEmpty or IsNull? Using a conditional statement to check for null or empty values should prevent these dates from passing through to your script. I was wondering if this is an ADO issue with the MYSQL column type of datetime, or perhaps an issue with the MyODBC driver and ADO ? If the data is already in the recordset, and the values for the other fields are correct, then I don't think that it would be an ODBC error. It might just be a matter of using some further code to verify the data before you use it in the rest of your scripts.

How do i put in an integrity constraint? ie. say i have 2 tables Person (PersonID[pk], PersonName) School (SchoolID[pk], SchoolName, PersonID[fk]) as you can see PersonID is the foreign key in School. So how do keep update and delete restricted constraints etc,? could anyone tell me the SQL code for bot the tables? duke. Sir, look up REFERENCES in the documentation.

Re:pulling audio out of a blob and playing it. = just a questionabout performance
(I think) most people figure that the disadvantages of having images and most other binary files stored within the DBMS far outweigh any advantages. From the top of my head... Advantages -- - tidiness - ease of backup - all data is in one respository. Disadvantages - - DB is bigger, therefore repairs/checks/etc take longer (?) - for website apps, you can have your binary files (eg images/wavs) stored under the web heirarchy, meaning that a mysql application is not required to retrieve the file from disk.

Subject: help on mysql tables

Yes, but notice that you put a constraint of NOT NULL on the field. This
means that there has to be a value in this field, in every record.
I HAVE TRIED THE FOLLOWING QUERY :
insert into test values("");
MYSQL COMMAND IS ACCEPTING THE ABOVE QUERY WHICH VIOLATES NOT NULL
CONSTRAINTS.
First problem is that you should specify a table field after the table name
and you should specify a corresponding piece of data in the VALUES portion
of your statement. Next, you need to make sure that the data you enter is
NOT blank since the field has a NOT NULL constraint. Finally, you should
encase your data in single quotation marks, not double quotation marks.
Therefore, change your statement to:
INSERT INTO test(name) VALUES('something');
If your table has only one field, you can also use the statement below:
INSERT INTO test VALUES('something');
Good luck,
Dennis

I don't use NT, so if there really is some reason MySQL on NT won't work through a TCP port, I would love to know (and add it to the list of reasons I run my dbs on linux or BSD) ;) On 3/27/01 8:57 AM, "Chad Nielsen" [EMAIL PROTECTED] wrote: Hi, I'm trying to install mySQL on NT Server 4.0 I guess I need to install a Telnet Server so I can manage mySQL from a workstation.

I can see in the mysql documentation that mysql works OK in a 2-way machine but that in a 4-way system has to be tested. Is this true? Or the documentation is not updated? Anybody out there with a 4-way machine that runs mysql without problems? (kernel 2.4.x glibc 2.2.12) Our DB has around 120.000.000 "questions" per week and our 2-way/1Gb system works OK, but the trafic is growing very fast and I would like to have a backup plan incase I need it. Thanks for your help. Rafael Martinez I've had MySQL running on a 12 CPU 16 GB machine running Tru64. Runs OK. I normally run it on a 4 CPU 4 GB machine and another one with 3 CPUs and only 512 MB. Both Tru64 Alpha. In recent (3.23) versions there are some my.cnf parameters related to SMP machines. You might want to take a look at them : set-variable= thread_cache=8 set-variable= thread_concurrency=8 # Try number of CPU's*2 The only problem I have is that there appears to be a problem with memory allocation when running MySQL on Tru64. I haven't found out exactly what the problem is, but the result is a crashed MySQL with a "Out of memory" error. Which is rather misleading since there is plenty of free memory and no ulimit or any other limiting kernel parameters. l8r/Jspr - 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: How to index this properly (to make it go faster) ?
-Original Message- From: Benjamin Pflugmann [mailto:[EMAIL PROTECTED]] Sent: martes, 27 de marzo de 2001 10:00 To: Nemholt, Jesper Frank Cc: '[EMAIL PROTECTED]' Subject: Re: How to index this properly (to make it go faster) ? [clip] Why that, usertime systemtime are data values, they are never used in any where clause. As far as I can see it's complete waste to put index on those. If all columns of the SELECT clause are part of the index, MySQL will solve the query only with reading from the index file and never touch the data file itself. Since the index is quite big already and usertime+systemtime only add 8 bytes per row, this may pay off regarding the speed win / size increase. Aha. I'll think about that, but I'll have to look in the logfiles to see if there's a pattern regarding what the users select. I don't think it's just usertime systemtime every time. [clip] Depending on the Cardinality of the different columns you may want to change the order to (username,processname,system_id,timecode) or alike. Aha, I'll have to test more with the individual order of combined indexes to see what I can get from it. Well, normally that is not really important, but in your case, processname has a low cardinality and therefore one value has a lot of matches in the index and it is worth a try to put it to the right. So the lower the cardinality the more to the right in a combined index ? [clip] May I bother you to add the following indexes and post the EXPLAIN after adding them:. (system_id, processname, timecode) (system_id, processname, timecode, username) (system_id, processname, timecode, username, usertime, systemtime) I'll try. Tonight I'm going for system_id, processname, timecode I will probably make the next tests on the disk table, since recreating indexes and analyzing/optimizing on the process table takes too many hours. The disk table only takes 20 minutes. Every explain ends up saying "where used" and the showing the full number of rows. This is in 3.22.32. My test setup is the latest, it might be different there. Well, using two different systems isn't a good idea, except if you plan to upgrade your 3.22.32 system, because if we find a solution on your test setup (3.23.?), it won't behave the same on the older MySQL. In most cases, 3.23 is faster than 3.22 (which is to be expected). I plan to upgrade asap, but had a few problems building the latest stable under 4.0f ev56. On a side note, with 3.22.32 I have some weird memory allocation problems. The database runs on a 4 CPU machine with 4 GB memory, and most of these 4 GB are free (or rather used for filesystem cache by the OS). The memory is free if any process want it. With the default settings (ie. no custom my.cnf) everything runs fine, but MySQL use allmost no memory which is not optimal given the size of the database indexes. If I instead use the my-huge.cnf that comes with MySQL which makes a key buffer of 384 MB, a big select makes MySQL crash with a "Out of memory" error. I have ulimit set to unlimited, and no memory allocation errors are logged to /var/adm/messages (Tru64 allways logs to that file if some user hit the limit of some sysconfigtab/kernel parameter). This means that the "Out of memory" error from MySQL was not caused but the OS disallowing mysqld to allocate more memory. I have tried this several times to be sure it's reproduceable. I get a crash every time. Is there a memory allocation bug in MySQL on Tru64 ? Anothing thing: If you cannot get it work with combined indexes, can you post some testcase (i.e. the SQL commands to build a sample database), so that we can play around and see if we have more luck? Sure. Everything will in fact be put on a web page soon, since it's a OpenSource solution. The database is used to store performance info for Tru64, Solaris Linux (and others soon).

RE: help on MySQL tables
Hi Rick,
You absolutely right, you are not required to specify field names in an
Insert. But it's a good idea to do so. 1) It makes you code more readable
for those following you. 2) If your table ever changes structure, your
Insert will still work. (Assuming you didn't remove one or more of the
fields you are inserting into.)

You DO NOT need to specify table field names when INSERTing records. For
instance, if the table were defined thus:
CREATE TABLE mytable (
valueA varchar(10) NOT NULL,
valueB varchar(25),
valueC varchar(30) );
This statement will insert one record:
INSERT INTO mytable VALUES("some text", "more text", "last text");
To insert multiple records, go with:
INSERT INTO mytable VALUES("some text", "more text", "last text"),("record
2","text for 2","last text in 2");

Subject: help on mysql tables
I have created the following table:
create table test(name varchar(10) NOT NULL);
query is ok
Yes, but notice that you put a constraint of NOT NULL on the field. This
means that there has to be a value in this field, in every record.
I HAVE TRIED THE FOLLOWING QUERY :
insert into test values("");
MYSQL COMMAND IS ACCEPTING THE ABOVE QUERY WHICH VIOLATES NOT NULL
CONSTRAINTS.
First problem is that you should specify a table field after the table name
and you should specify a corresponding piece of data in the VALUES portion
of your statement. Next, you need to make sure that the data you enter is
NOT blank since the field has a NOT NULL constraint. Finally, you should
encase your data in single quotation marks, not double quotation marks.
Therefore, change your statement to:
INSERT INTO test(name) VALUES('something');
If your table has only one field, you can also use the statement below:
INSERT INTO test VALUES('something');
Good luck,
Dennis

MySQL vs MS-SQL performance
Hey guys, Most of the accounts I have read about MySQL was that it was one of the fastest databases around. Now, for development purposes I created a FreeBSD system with JUST MySQL (no other major processes). Then I created a separate Windows 2000 ASP server to server as our development server for our new site. The two servers communicated via ODBC. Anyways, a period of time elapsed and we decided to move to MS-SQL server for feature reasons, and when we had the MS-SQL ODBC driver point to the newly created MS-SQL server (roughly same specs), it was like 50% faster! What gives? Is MySQL *really* that slow, MS-SQL *really* that fast, or maybe there was some weird setting in the ODBC driver or the MySQL server that I didn't switch right which made it go slow. I am not sure. Or maybe Microsoft, in their monopolistic ways, created special hooks between ASP and MS-SQL server to make the communication go somehow faster. Anyone had similar experiences to mine? - Steve

On the other hand, I only happened to come across this twice (I mean, that changing the order of combined index resulted in an speed increase), and I don't know too much about the internals of the trees used in the MySQL indexes, so take this with a grain of salt. I think, it is of interest, what the Cardinality of the sub key is, i.e. if you only have 20 different usernames, but system_id splits them up (i.e. only 20 entries for each system_id), of course, you don't need to think about. But you it probably works with 20 different usernames, which each 'contain' 1 system_id's. Then it's better to start with the system_id, I think. Someone may want to correct me, if I am mistaken. Just try if it helps, and if not, ignore my suggestion. [...] I'll try. Tonight I'm going for system_id, processname, timecode I will probably make the next tests on the disk table, since recreating indexes and analyzing/optimizing on the process table takes too many hours. The disk table only takes 20 minutes. Good idea. [...] On a side note, with 3.22.32 I have some weird memory allocation problems.

Any suggestions?
Thanks for the time!
Have you tried putting the returned value into a variable, opening up a file
for writing(as binary)
In php (which it looks like you are using)
$fh=fopen('newfile.wav','wb');
fputs($fh,$fielddata);
fclose($fh);
I think that selecting into an outfile does some textencoding and newline
conversion type stuff (just guessing).
The above is the way I would do it, if I had to put my files into a db.
I would rather store my files, as files, in a directory, and store the meta
information (file location, name,size,description,copyright whatever) in the
database.
It is so much easier to have the file path/name inserted into the html, than
to pull all the data out, create the file, insert the filename, server up
the html.

Re: New ODBC
Yes, your grant tables are not set up correctly. For full information, see the manual. For now try this: Choose a userid and password just for your db connection. It can be different from every other userid password you have. With the mysql client issue the following to SQL statements GRANT ALL ON *.* TO userid@%.uni-karlsruhe.de IDENTIFIED BY 'password'; FLUSH PRIVILEGES; Then try to connect with ODBC using the above userid and password. The effect of the GRANT statement allows userid to connect from any machine in the un-karlsruhe.de domain. The *.* means all databases and all their tables. The % is the wildcard that MySQL needs to allow the domain match. If your connection is always going to come from the same host, you can put that exact hostname or ip address after the @ in that section. MySQL maintains a totally separate user list from the system it is on, which is why you are getting the error. On 3/27/01 6:34 PM, "Wawan Setiawan" [EMAIL PROTECTED] wrote: Hello, I'm new here ...

RE: Progress DB to MySQL DB
Has anyone seen any tool that would connect to a Progress DB and dump out a .sql (DB structure data) so I can then load it into MySQL. I know very little about Progress, but... I have managed to get PHP http://www.php.net talking to both MySQL and Progress 8.3 using the openlink drivers http://www.openlinksw.com Using the functions from within php you can extract information about tables and then build create statements and then transfer the data. It works very well. You could also write some kind of script that would convert a progress .df file into true SQL TABLE statements. Also, another thing I want to achive is to be able to run Progress 4GL code against MySQL DB. Has anyone heard anything about this before? Pass. Although Progress do have a product that talks to ODBC data source (which would include MySQL). Hope this helps.
