Re: Borland C++ Builder 2006 DLL Woes
I had to buy dbExpress libraries for MySQL from third party. Dusan [EMAIL PROTECTED] napsal(a): We just purchased The Borland Developer Studio 2006 IDE and are having significant problems using dbExpress objects to communicate with MySQL servers (both 4 and 5). Curiously, we can perform inserts but not selects, even though identical code in C++ Builder 6 worked just fine. The DLL in C++ Builder 2006 is dbxmys30.dll. Anybody having similar issues?

mysql problem
I have a database online and have a strange mysql problem. When I connect remotely from my desktop (same browse_database.php page) I get over 1000 results with the query below but when I run the same page on the remoted server this value is almost halved to 520. any ideas what is hapening? $total_rows = mysql_num_rows(mysql_query(SELECT * FROM $table_name)); It just seems to ignore them on the remote one as I am in under ross and ross2 and only one when I search for me.

RE: MySQL Daylight Savings Time Patch
I think that's only true if the server is using the default system time zone. In addition, you can set a per-connection time zone and use time zone sensitive functions such as CONVERT_TZ(). All of these mean that MySQL needs to be aware of time zone definitions. There could also be trouble if you are using replication across time zones, I suspect. There are explicit instructions for building time zone tables in section 5.9.8 of the manual.

Arbitrary Docs Machinery
The MySQL documentation team has created a way that enables us to extract arbitrary pieces of MySQL documentation and recombine them into a new document. With that machinery for creating arbitrary docs, we could, for example, do this: * Bond the Cluster docs with the rest of the Storage Engines. * Create a Cluster and Partitioning standalone guide. * Collate all the Windows sections into a single document. * Create a Connectors/APIs document where each of the current connector sections is a chapter in the new book. * Put a section anywhere, and remap any section to any block (i.e. section to chapter or appendix, chapter to appendix, you name it). Basically, we can combine excerpts from any documentation that can be found on http://dev.mysql.com/doc. The arbitrary docs machinery doesn't work in a copy-and-paste manner, but rather by including blocks (chapters, appendices, or sections) of the original documentation. This means that whenever the underlying documentation changes the arbitrary docs will also change. (You may have noticed that this concept is similar to views in a database.) This is what our users can do with that machinery: 1. Look at our sample PDF file that demonstrates what can be done; it combines all Windows-related installation instructions from various docs files: http://svn.mysql.com/svnpublic/mysqldoc/arbitrary/windows-sample.pdf 2. Tell us ([EMAIL PROTECTED]) which new excerpts or combinations of documents you'd like us to create and make available on http://dev.mysql.com/doc. 3. Create arbitrary docs yourself. For this, you can find everything you need in the public copy of our mysqldoc repository (viewable with any web browser) on http://svn.mysql.com/svnpublic/documentation. To see how creating your own arbitrary documents works, try our sample files: 1. Use Subversion (SVN) to pull a working copy of http://svn.mysql.com/svnpublic/mysqldoc. 2. You need an environment that has make and xsltproc installed (any Unix-like system, or Cygwin on Windows). To create PDF files, you also need fop. 3. A sample arbitrary specification file (windows.aspec) and the necessary DocBook wrapper (windows.xml) are located in the arbitrary directory. A sample of the file generated from that specification is provided as windows-sample.pdf. 4. To generate HTML or PDF output for yourself: * Change to the upmost directory and run make realclean - this will clean out any old and temporary files. * Change to the arbitrary directory and run make idmap.refs - this will rebuild all the ID map reference files which are required for the arbitrary functionality. * Within arbitrary, run make windows-arbitrary.pdf to make the PDF version, or make windows-arbitrary.html to create the HTML version.

Running 4.1.22, on windows 98, I'm having trouble getting
the time zone
tables to actually work. I've loaded the tables as per:
http://dev.mysql.com/downloads/timezones.html, and followed the
diagnostics
as per: http://lists.mysql.com/mysql/205115
.
It appears that my results from said diagnostic indeed prove that my
tables
are correct. However, I don't see those tables being used.
The following

machines (I run about
ten servers).
SELECT DATE_FORMAT(from_unixtime(unix_timestamp('2007-4-1

The linux machine -- with empty timezone tables is correct.
2007-3-11 and
2006-4-2 result in midnight plus 2 hours being 3am --
correct in the past
and correct in the future. On my modern XP machines, the future is

and the past is incorrect. On my older XP/98 machines, the past is
correct
and the future is incorrect. It is on my 98 server that I
am now playing,
having loaded timezone tables, and going crazy. I have

Result of select is broken by running another select
Hi all, I have an extremely strange problem here. A particular part of a project I work on has two SQL queries -- both selects, both join similar tables, and neither modifies anything. Running the first one works until I run the second. After that, running the first returns no results (it previously returned 1 row). The only way to make the first run again is to comment out a particular part of it (which is also in the other query) and run it. Uncommenting that part then makes it run as usual until the second query is run again. I can provide more information on the actual data and tables involved if required but am leaving it out for now as I have a feeling this may be some sort of caching issue (because of the repeated part of query being key to making it work again). If anyone feels this information may assist in diagnosing the problem please let me know. The first query (the one which breaks) is this: SELECT * FROM privilege Paccess JOIN privilege Phome ON Phome.user_id = '26' AND Phome.type = 'network-member' -- AND (Phome.network_id = Paccess.network_id OR Paccess.network_id IS NULL) WHERE Paccess.user_id = '4' AND Paccess.type = 'user-manage'; The commented out line is the one which must be commented to make it run again. The second query (the one which makes the first one break) is this: SELECT U.id, U.name FROM user U -- find each user's home network JOIN privilege Phome ON Phome.user_id = U.id AND Phome.type = 'network-member' -- current user's user-management access rights LEFT JOIN privilege Paccess ON Paccess.user_id = '4' AND (Paccess.network_id = Phome.network_id OR Paccess.network_id IS NULL) AND Paccess.type = 'user-manage'; You can clearly see the second to last line is repeated from the first. This is running on MySQL Ver14.12 Distrib 5.0.22 for Win32 on a Windows 2000 box. I have set up a Windows XP box with same version and duplicated the database content onto it but cannot replicate the problem there.

Re: row count inconsistency
The table was created and then loaded and not modified in any way I'm aware
of afterwards. It's on a local, only accessible by me server.
Really weird thing about it is that I wrote/ran a program specifically to
find any gaps in the id sequence - because of the size of the table it took
days to run but the result was
1-100537311
IOW it confirms the max id that Mysql gave, but also indicates that there
are no gaps in the row id's all the way through. This doesn't make sense to
me in light of Mysql reporting the count as posted previously i.e.
mysql select count(*) from fidcid;
+---+
| count(*) |
+---+
| 100480507 |
+---+
1 row in set (0.09 sec)
I did do some testing before letting the program run, but here's the main
code:
my($cur,$prv,$rating,$line) = (1);
$line = $cur-;
for $cur(1..100537311)
{
$rating = getDat $DB
({table='fidcid',cols='id,cId,fId,ring',cond=id=$cur});
if($prv != $cur-1) { $line .= $prv\n; print $line; $line = $cur-
}
$prv = $cur;
print $cur at ,`time /T\n` if not $cur % 10
}
print $line,100537311\n

3 rows in set (0.00 sec)
mysql delete from test;
Query OK, 3 rows affected (0.00 sec)
mysql insert into test values (null),(null),(null);
Query OK, 3 rows affected (0.01 sec)
Records: 3 Duplicates: 0 Warnings: 0
mysql select * from test;
++
| id |

You can either drop/recreate the auto_increment field or explicitly
reset it using an
alter table tablename auto_increment=1
statement. See

Here's an example of what I mean: So first of all here's the SQL that gets me the data I want: SELECT DISTINCT(applicanthistory.contact_id) as cid, ( SELECT statustype.statustypelabel FROM statustype, applicanthistory WHERE statustype.statustype_id = applicanthistory.statustype_id AND applicanthistory.contact_id = cid ORDER BY applicanthistory.statusdate DESC, applicanthistory.statustype_id LIMIT 1 ) as currentstatus FROM applicanthistory It returns this: +-+---+ | cid | currentstatus | +-+---+ | 1 | N | | 2 | N | | 3 | N | | 4 | N | | 5 | N | | 6 | P | | 7 | N | | 8 | N | | 9 | N | | 10 | N | +-+---+ Here's the SQL used to create the view: CREATE VIEW contactextension_view AS SELECT DISTINCT(applicanthistory.contact_id) as cid, ( SELECT statustype.statustypelabel FROM statustype, applicanthistory WHERE statustype.statustype_id = applicanthistory.statustype_id AND applicanthistory.contact_id = cid ORDER BY applicanthistory.statusdate DESC, applicanthistory.statustype_id LIMIT 1 ) as currentstatus FROM applicanthistory When I do this: SELECT * FROM contactextension_view; I see: +-+---+ | cid | currentstatus | +-+---+ | 1 | N | | 2 | N | | 3 | N | | 4 | N | | 5 | N | | 6 | N | | 7 | N | | 8 | N | | 9 | N | | 10 | N | +-+---+ Notice cid = 6. The results from the first query (not the view) are correct. Why oh why would the view show something different from the sql that is used to create it? I thought a view was more or less just an alias for a query.

Running 4.1.22, on windows 98, I'm having trouble getting
the time zone
tables to actually work. I've loaded the tables as per:
http://dev.mysql.com/downloads/timezones.html, and followed the
diagnostics
as per: http://lists.mysql.com/mysql/205115
.
It appears that my results from said diagnostic indeed prove that my
tables
are correct. However, I don't see those tables being used.
The following
statements yield varying results on my linux/windows
machines (I run about
ten servers).
SELECT DATE_FORMAT(from_unixtime(unix_timestamp('2007-4-1
00:00:00') +
2*60*60),'%H');
SELECT DATE_FORMAT(from_unixtime(unix_timestamp('2007-3-11

SELECT DATE_FORMAT(from_unixtime(unix_timestamp('2006-4-2

SELECT DATE_FORMAT(from_unixtime(unix_timestamp('2006-3-12
00:00:00') +
2*60*60),'%H');
The linux machine -- with empty timezone tables is correct.
2007-3-11 and
2006-4-2 result in midnight plus 2 hours being 3am --
correct in the past
and correct in the future. On my modern XP machines, the future is
correct
and the past is incorrect. On my older XP/98 machines, the past is
correct
and the future is incorrect. It is on my 98 server that I
am now playing,
having loaded timezone tables, and going crazy. I have
upgraded my win98
timezones via a registry update.

Thanks Try InnoDB or PBXT (http://www.primebase.com/xt) :) for the time being, I'm going to stick with MyISAM.

Here we go - it's weird, but it might work. I use a default value, which is itself a foreign key that point to a meta-table example status int(6) default 1, 1 is the ID for a table with columns `ID` 'descriptor`, where the desciptor field holds something like this provider_status.ID.title the script executes the show cols query, then queries the metadata table where provider_status.ID.title tells the script to pull `ID' and `title' from provider_status and load the values into a select/option list form entity. I'm sure that this will not be optimal performance-wise, but where speed is not an issue, will save much coding time. Since it will be the weekend before I try this out, I welcome observations and any references to meta-data approaches using MySQL /MyISAM.

I¹m running MAMP (www.mamp.info) on my Mac OSX box as a local way of developing. I¹m running into a slight problem that the mamp site doesn¹t talk about. The 1.5 beta1 seems to have the option skip-innodb enabled and I can¹t seem to find out where this is located to disable it and enable the use of innodb tables. There is no my.cnf or my.ini file and the command to start MySQL is: /Applications/MAMP/Library/bin/mysqld_safe --port=8889 --socket=/Applications/MAMP/tmp/mysql/mysql.sock --lower_case_table_names=0 --pid-file=/Applications/MAMP/tmp/mysql/mysql.pid --log-error=/Applications/MAMP/logs/mysql_error_log I was wondering what I can do to enable innodb? The only thing I can think of is that the people who make MAMP have disabled innodb when they compiled MySQL in which case am I out of luck? Thanks.
