BUG: MySQL 5.1.19 with UNCOMPRESS on *VALID* data fails when generated by 3rd party zlib.
OK I think I've found a bug with MySQL's compression support. :-/ I'm using two Java zlib implementations. One is jzlib 1.0.7 and the other is java.io.DeflateOutputStream . Both of these are referenced by the zlib implementation as being compatible. I can compress/uncompress locally WITHOUT a problem. When I store the data in the DB the value is stored correctly in a blob and I can compare the MD5 hashcode with my local array of and the hashcode values are identical which for all practical purposes means they're the same. The only problem is that UNCOMPRESS won't work... It returns null and I get: mysql> SHOW WARNINGS; +---+--+-+ | Level | Code | Message | +---+--+-+ | Error | 1256 | Uncompressed data size too large; the maximum size is 1047552 (probably, length of uncompressed data was corrupted) | +---+--+-+ 1 row in set (0.00 sec) Sure enough: mysql> SELECT UNCOMPRESSED_LENGTH(BODY) FROM FOO; +---+ | UNCOMPRESSED_LENGTH(BODY) | +---+ | 147577464 | +---+ 1 row in set (0.00 sec) .. I've tested this on 5.1.19 and 4.1.21 with the same symptoms. Anyone have any advice here? Did you guys make any changes with the zlib implementation you're using? I'm willing to file this as a bug if necessary. Kevin -- Founder/CEO Tailrank.com Location: San Francisco, CA AIM/YIM: sfburtonator Skype: burtonator Blog: feedblog.org Cell: 415-637-8078

It's a requirement of the ODBC/JDBC/OLEDB/.NET specifications. I suppose we could scan the table twice to figure out how large a column might be, but that would make the PostgreSQL driver run at 1/2 speed. Not a very appetizing solution.

If you key the database properly, search times should be very modest. I can't speak for insert times, though, especially when keys are involved. This kind of thing is easy enough to do in your favorite scripting language. I would just create a table with a few keys and just for($i=0; $i<9900; $i++) it with random numbers. If you have PHP on your system, here is some PHP code (runnable from the command line) that you should be able to hack down.

You can even do test queries using the barebones MySQL client ... you should see interactively how long a query takes.

I imagine the reason for this "never-ending fascination ..." is along the lines of education. To the uninitiated, the idea of binding variables seems weird and unintuitive. "What?! I don't want them to be bound! They're variables! They're supposed to change." Okay, so it's a slight exaggeration, but I think the point is still good. A lot of folks pick up MySQL by fiddling around in their spare time. Unless someone (among my friends, it's usually me) enlightens them to better ways of doing things, and reasons for doing something in a more abstract, not-always-immediately-intuitive way, folks just don't know any better. In that sense, this very discussion is /exactly/ what the magazine article should be creating. For those who don't know, binding is a process that does two things: 1. Lets the database pre-parse a query This can give enormous boosts in speed because a large amount of the time involved in getting information from the database is spent in parsing and planning a query. If you're planning to do the same query many times over with only one or two different parameters, why not only parse and plan it once, and then aggregate the cost over / all/ the executions? 2. as well as let the database do any escaping necessary. The database designers ostensibly know best what characters need to be escaped, so let them do it. Besides, no sense in having multiple definitions around, or reinventing a wheel, or wasting your time doing something mundane.

Re: Building RPMs with ICC
Having just tried building MySQL 6.0 SRPM on CentOS/RHEL 5, it would appear that it doesn't even build cleanly with the default settings with GCC! Has anyone got any information as to why this might be? It seems to build OK, but then all the tests (mysql-test-run) seem to fail.

Re: MySQL Magazine - Issue 1 available NOW!!!!
Oh dear... Without getting into any religious arguments, if you have to
use it, PHP already provides a perfectly good interface for preventing
any SQL injections - ever. Use MySQLi and bound parameters. And if
somebody manages to invent some quasi-valid reason for not using MySQLi
(e.g. version of PHP used), then there is always mysql_escape_string() /
mysql_real_escape_string().
I don't understand this never-ending fascination with re-inventing a
square wheel for an application for which the standard round type has
already been kindly provided since year dot.

Insert into multiple tables using auto_increment reference
Hi,
Is it possible to insert values into two tables simultaneously and
have the value of one of the columns in the second table be the
auto_increment value from inserting into the first?
E.g. if table1 has an auto_increment column c1, the logic I'm looking
for would be something like:
INSERT INTO table1(c2, c3, c4), table2(c5, c6, c7) VALUES ('v1', 'v2',
'v3', table1.c1, 'v4', 'v5');
where table2.c5 is a reference to table1.c1.
Thanks,
Hamish

determining if tables are being used
I have inherited database servers from a group whose main job was not working on mysql. I am not certain if all the tables on the databases are being used. Is there some efficient way of determining if a table is being accessed or when the last time it was accessed?

How to set table-specific privileges
Hello, I am trying to revoke all privileges from a user on a certain table in a database. I want the user to continue to have all his/her privileges intact for the other tables though. I used the statement "REVOKE ALL PRIVILEGES on dbName.tableName from thisUser"; But that doesn't seem to change anything. The message always gives "Query 0K, 0 rows affected..." What could I be missing. Thank you. -- http://www.spreadfirefox.com/

Have you looked at mysql_info()? The format of the return value might not be the most useful, but it should give you what you need.

If your load is so high that the whole system is grinding to a halt, that indicates one or more of the following: 1) Your database isn't configured properly. 1.1) This may mean you have to allocate more memory to it in my.conf, but more likely, 1.2) you either have a poorly designed query somewhere in the calling code, or most likely 1.3) a missing index on a frequently used table 2) Your server isn't up to the job Have you enabled logging of slow queries in my.conf to see what queries are taking a lot of time to execute? What table type are you using? Is your data access mainly reads, mainly writes, or a combination of both? If it's both, you may benefit from using InnoDB tables instead of MyISAM, assuming this isn't what you are doing already. The first thing to find is what queries are taking up a lot of resources and making sure they are running fully indexed, and/or possibly changing the data structure to better suit the query requirements.

Building RPMs with ICC
Hi, I'm trying to build the RPMs with ICC, but I'm not having a lot of luck. I saw the documentation for what paremeters are used to combile the tar balled binaries, but can anyone give me some guidance on how to get the RPMs to build? The distributions I want to build for are CentOS 5.0 / x86_64 and RedHat 9 / pentium3. At the moment I have tried the following: export CC=icc export CXX=icpc export MYSQL_BUILD_PATH=$PATH export CPATH=/path/to/my/icc/includes export LIBRARY_PATH=/path/to/my/icc/lib Added ICC libs to ld.so.conf Changed parameters on icc in ~/.rpmrc: optflags: x86_64 -O3 -march=pentium4 -mtune=pentium4 -mcpu=pentium4 -msse3 -xP -no-gcc -restrict -ip -mp -funroll-loops which is pretty close to the documented example. I had to add the -march/-mtune/-mcpu parameters because it looks like the default Makefile somewhere was trying to substitute x86_64 in there, and this is not a valid value for ICC v9.1 (thus causing it to abort). Instead it now just issues a warning and says that it is overriding pentium4 with -msse3, but proceeds with building. Then I tried: rpmbuild --define "__cc icc" --rebuild MySQL-6.0.0-0.glibc23.src.rpm Then things fail at various points. Then I doctored the rpm file to exclude building of NDB, InnoDB and most other optional DB engines (I only really require MyISAM, but I'm tryign to be a bit future facing so I'm usiong 6.0 instead of 5.x). Eventually I get a segfault from the linker and static mysqld library fails to build, at which point the process dies. Is there any more detailed guidance available for building RPMs with ICC?
